White Gold Net Zero Renovation

A 'Net Zero Ready' Renovation

RDC Fine Homes' President Bob Deeks provides updates for a home renovation project in the Whistler White Gold neighbourhood. This renovation is a "Net Zero ready" project.

Update 1 (January 13, 2021)

RDC Fine Homes' president Bob Deeks provides an update on our a new home renovation project in Whistler's White Gold neighbourhood. Bob discusses some of the decisions made to renovate or rebuild for this project. Bob also outlines the overall plans for this Net Zero Ready home reno.

Transcript Update 1

Bob Deeks:

"Hey there, Bob Deeks with RDC Fine Homes up here in beautiful Whistler, British Columbia. I am standing out in front of our newest project, which is going to be a Net Zero Ready renovation. Demolition just underway. We've got our great hazardous waste removal partner here, Urban Environmental. They're on the top two floors doing our asbestos abatement, asbestos in the drywall, and some asbestos tiles on the floor. They're well underway and should be done towards the end of next week.

This is an exciting project for us, a lot of debate around whether to rebuild or renovate. And in the end, the decision was made to renovate this, which is awesome for us because it keeps a lot of material out of the landfill. Although we'll remove the top two floors, we save all the bottom floor framing and all the concrete and likely saves us at least two to three months in our construction timelines. We are going to panelize the new structure in our panel shop here in Whistler, and we have an aggressive goal to get our client back inside his new house for Christmas of 2021.

So, stay tuned. If you want to get updates, make sure to subscribe to the YouTube channel to follow along on this exciting Net Zero renovation."

Update 2 (February 19, 2021)

RDC Fine Homes' president Bob Deeks provides the second update on our new home renovation project in Whistler's White Gold neighbourhood. Bob reviews the project's recycling station, our COVID safety plan, and updates in progress for the bottom floor of this home.

Transcript Update 2

Bob Deeks: (00:00)
Hey there, Bob Deeks from RDC Fine Homes here at our latest net zero renovation project up here in beautiful Whistler, British Columbia. The boys are getting ready for their first concrete pour coming up today, pouring some footings to support some of the new roof loads for the new structure. As you can see, we've got our great partners Sea to Sky Welding on site, doing a little bit of fabrication for us. So let's go on inside and see what kind of progress we have made to date.

Bob Deeks: (00:32)
Go on inside. As you can see, we've got our recycling center all set up, all the bins protected with a little bit of scaffolding to keep the snow out. Don't want to be throwing away snow. COVID rules posted on the fence here, site safety rules, and of course our own site signage up there looking great. Walking on inside, we've got our Nudura ICF forms all ready to go for the extension of the garage and a bedroom up above, and a little bit of ICF work here also for the expanded front entry. So let's go on inside and see what's going on in there.

Bob Deeks: (01:17)
Right inside on the bottom floor, this is the level that we are keeping. So we've actually done quite a lot of cutting and coring here on the original slab to get ready for all the new structural bearing points, and as of course you can see, we've got all our plumbing rough-ins now complete as well. So little bit of a footing pour today, and then beginning of next week we will repour the slab and make everything good. All the demolition is now complete with regard to removal of drywall, any of the hazardous waste materials. Of course, just about everything on this floor will remain.

Bob Deeks: (01:57)
And one of the latest developments for us will be using NRCan's (Natural Resources Canada) new embodied carbon calculator, so very excited to run this project through that calculator to see what sort of carbon emissions we have saved by using the bottom floor framing, and most importantly here would be all the concrete works, because on the project we just ran, one of the largest amounts of carbon in a new house was of course the foundation. So stay tuned for some further updates, and of course, if you want to follow along with this, make sure to subscribe to our YouTube channel. Thanks.

Update 3 (February 25, 2021)

RDC Fine Homes' president Bob Deeks provides the second update on our new home renovation project in Whistler's White Gold neighbourhood. Bob reviews the project's goals as well as the latest ICF and plumbing updates.

Transcript Update 3

Bob Deeks (00:00):
Hi there. Bob Deeks with RDC Fine Homes, I am out in front of our latest Net Zero renovation project here in beautiful Whistler, British Columbia. And if you are just joining us on this video series on this exciting project, we've been here about six weeks. Boys have completed the majority of demolition inside, hazardous waste materials have been removed by Urban Environmental, and we are working on the framing on the lower floor. The RMOW (Resort Municipality of Whistler) just showed up for the plumbing inspection for all the lower floor rough-ins.

Bob Deeks (00:34):
(The) strategy here is we're going to get all the concrete works done. We are going to address all our structural framing requirements on the bottom floor. And then, we are going to panelize all the new walls and roof components in our panel shop. And once that's done, the top two floors of the house will be removed, and we will assemble the new structure sitting on top.

Bob Deeks (00:56):
One of the exciting things about this project as a renovation, because there was debate around whether or not this house would be constructed new, or whether we would work off the existing foundation and lower floor walls and design around it as a renovation, is that we will save significantly on the embodied carbon during the construction process. And we have just recently been able to get hold of NRCs (National Resource Canada's) latest embodied carbon calculator. And so the task for next week is we're actually going to run some numbers to see just how much carbon we will have saved by using the existing foundation and lower floor walls, which is going to be an exciting development for us as we really dig into the embodied carbon on all our projects.

Bob Deeks (01:42):
So let's go on inside. We'll see where the boys are at. The plumbing inspection, as I noted, is today, and the slab is ready to be repoured tomorrow. So we'll go in and look and see what they've done. So part of the scope of this project is we're going to do a bit of an addition on the front face here of the garage. That'll make the garage a little bit bigger and create a little more living space up above. What you can see there are the Nudura insulated concrete forms, and all ready to be poured tomorrow.

Bob Deeks (02:10):
And then we've got a little bump out on what is going to be the new front entryway here. Again, using Nudura's insulated concrete forms. One makes for a really easy forming process, even for these little jobs, and just adds a little bit of extra thermal performance to the new components of the house. And, of course, every little bit helps to help get us to that Net Zero Label standard.

Bob Deeks (02:34):
One of the things that we've had to do here is do some significant work for the new bathrooms, kitchens, and what have you on the revised plan for the house and design. So what you can see here is new plumbing rough-ins for the sanitary and drains. And, of course, some new bump-outs here for some of the new components. We're just doing the plumbing inspection right now.

Bob Deeks (03:03):
What you can see right here, to repair the vapour and air membrane under the slab, rather than trying to fit in the 6-mil poly and tie it nicely together with the poly that was underneath the existing slab, we've just brought in a pack of two-pound spray foam. So what would have taken one of the guys probably two days to try and detail that air and vapour barrier under the slab took one of the guys about an hour. So great time-savings and this will create a much more airtight assembly, and of course, adds a little bit of extra insulation under the slab.

Bob Deeks (03:44):
If you were paying attention to our Instagram account earlier last week, you would have seen a picture of this steel beam all clad in wood, and here is a great shot of the beam in place. And we needed this to carry the new structural roof load from above and to ensure that we kept the nice flush ceiling on the floor below. So that's some new construction that's been added into the existing structure that will enable the future construction that's to come when the new panels and the new roof show up, sometime in April.

Bob Deeks (04:21):
Look at progress to date, plumbing inspection underway over there, you can see all the new plumbing rough-ins. Once this has passed, of course, we'll use the two-pound spray foam, and we will fill in all these cavities to seal up our air and vapor barrier under our slab and getting ready for our pour tomorrow. A little bit dark in here. And of course, if you want to continue on with the story, please subscribe to our YouTube channel and follow along on our Instagram account. That's all for today.

Update 4 (March 5, 2021)

RDC Fine Homes' president Bob Deeks provides the fourth update on our new home renovation project in Whistler's White Gold neighbourhood. Bob reviews the panelization process for this home renovation. This includes building wall panels offsite, then moving them to the construction site when ready.

Transcript Update 4

Bob Deeks (00:00)
I'm Bob Deeks with RDC Fine Homes. I am here in front of our mini panel shop. The boys just started this week fabricating all the walls for our Net Zero renovation. They'll be in here for the next couple of weeks fabricating away. Pretty epic day today and last night we had a very traditional pineapple express come through. Over 40 centimeters of snow on the mountain, another 20 to 30 today, and overnight tomorrow. So Saturday should be a truly epic Whistler ski day, but for now let's zoom around. We'll have a look at some of the progress the boys are making in the panel shop here.

Bob Deeks (00:36)
Got the trailer all set up, you can see underneath that white tarp, or maybe you can't see. First couple of interior walls have been loaded onto the trailer. We are going to fabricate all the walls in the opposite order in which they have to be installed. I think we're planning for two trailer loads. So as they fabricate, they will load the walls on the trailer here. This trailer is full. It'll go into storage. Next trailer will come in, and two to three weeks as I noted, we should be ready to assemble onsite.

Bob Deeks (01:08)
Here just one little wall sitting on the zoom boom here with the Graphite Impregnated BASF Neopor EPS insulation. That gives us just under an R5 value per inch for our exterior insulation. Just having a quick look here, boys at work assembling a wall. You can see in the very background there they've got a wall assembled with the Neopor on it, just coming to the close of, I think of our first formal day of a full-on production. So stay tuned. And if you would like to follow along, please make sure to subscribe to the (RDC Fine Homes) YouTube channel or follow us on Instagram. Thanks for watching and stay tuned for more updates.

Update 5 (March 11, 2021)

RDC Fine Homes' president Bob Deeks provides the fifth update on our new home renovation project in Whistler's White Gold neighbourhood. Bob reviews the importance of choosing to do this project as a renovation compared to a full 'takedown rebuild'.

Transcript Update 5

Bob Deeks: (00:00)
Here from RDC Fine Homes. I am back at our Net Zero renovation. We are in the second week of March and I thought we'd do a quick tour through to see how the boys are doing.

Bob Deeks: (00:13)
It is absolutely a beautiful day here in Whistler, almost light spring. You can see the sun is out. And of course, given it's still the early part of March, the ski hill in full operation. We have fantastic conditions right now. A lot of snow over the weekend and looking for an additional dump of snow I think coming towards the end of next week.

Bob Deeks: (00:37)
So, if you're in Whistler and you're skiing, you're lucky. If you're not in Whistler and you're not skiing, well, too bad for you. Anyway, let's go on inside and we'll see how the boys are making out. Work underway. Demolition, of course, most of it has been completed on the inside.

Bob Deeks: (00:53)
All the interior finishes have been removed. And the boys are getting ready for I think Tuesday next week. And the roof sheeting is already off and the crane will be coming in. And we will be removing the top two floors here in sections and craning them off.

Bob Deeks: (01:12)
Of course, we are trying to divert as much of the waste from this demolition, divert as much of the waste from landfill as we can. So, recycling where possible and then making sure the wood waste goes to the composter in Squamish here.

Bob Deeks: (01:29)
One of the key goals of this project is to reduce the carbon footprint of the build. And one of the great advantages of keeping the bottom floor concrete and the bottom floor framing here is that we will really significantly reduce the embodied carbon in constructing this house, which in the end will really look like a brand new house.

Bob Deeks: (01:49)
And of course, if you've been following along, you'll know that this is targeting as a Net Zero renovation. It would also meet Step 4 of the BC Energy Step Code. And sometime towards next year, we will be putting solar panels on the roof to satisfy that Net Zero renovation qualification.

Bob Deeks: (02:11)
Inside, just a quick look, all the new interior walls are framed. The floor has all been filled in. We, of course, had to redo all our plumbing rough-ins here. And the boys are working away on building the new set of stairs. The new floor in over the garage is in place.

Bob Deeks: (02:28)
There have been some great update photos on our various sundry platforms here, so you can follow along a little more day-to-day as we move along. And if you would like to get notification on updated videos on this exciting project, then make sure to subscribe to the YouTube channel and follow us along on Instagram and Facebook. Thanks very much for watching and stay tuned for the next update.

Update 6 (March 31, 2021)

RDC Fine Homes' president Bob Deeks provides the sixth update on our new home renovation project in Whistler's White Gold neighbourhood. The top two floors of this home are removed. We keep the bottom floor and this helps with construction timelines as well as keeping a lot of fill out of the dump. Explore the next step in this home renovation with us!

Transcript Update 5

Bob Deeks (00:00):
Hey, Bob Deeks here with RDC Fine Homes. We are at our Net Zero Reno here in beautiful Whistler, British Columbia. And we are just in the process now of doing the demo, the formal demo, on the top two floors of the house. Of course, if you've been following along you know that we've been rebuilding the bottom floor and doing some foundation works because we're keeping the existing foundation and the bottom floor. We are in the process of finally removing the framing components here for the top two floors. Getting ready to install our panelized wall and roof components, which are right now being built off site. So crane just lifting a roof section off. We needed to carefully remove the top two floors so that we didn't demolish or damage the underlying structure that we want to keep. So the guys have spent the last week preparing the structure so that we can take this off in sections in a way that is safe and sustainable.

Bob Deeks (01:04):
Back at our Net Zero Renovation. Day two of formal demolition of the existing structure. As I noted yesterday, we are removing the top two floors of this early 1970s Whistler residence. Getting ready to assemble our pre-panelized walls, floors and roof components in a couple of weeks. We have successfully removed one half of the roof and as you can see here, they are just in the process of removing the second last panel from the main roof. Just walking around you can see that the roof over the garage is now off. All done. And with a couple more panels on the main roof here today, they will remove the walls on the second floor tomorrow. And we are about 10 days out from assembling the new structure on top of it.

Bob Deeks (01:59):
So pretty exciting project for us, particularly with regards to the prefab panelization component. All removed framing is complete and ready for our paneled walls, our prefabricated timber frame from FraserWood down in Squamish. And the boys are just tidying up. They're actually ahead of schedule by a day. So they're going to take an extra day on the Easter long weekend. So the last day here. Monday we see wall panels showing up and then later in the week we'll see all the prefabricated timber frame components and roof components coming in. Hopefully end of next week, we'll have some great shots of a house. So if you're curious to see what it looks like to see a house go up in a week. I'm recognizing we got the first floor done here. And absolutely look for the next video series that comes out for that assembly.

Bob Deeks (03:11):
You can see here all the interior wall framing on the bottom floor of this renovation has been completed. For those of you who are just tuning in, we have salvaged the bottom floor framing of this old 1970s house and the entire foundation and reworked it for what will be a transformation. Completely new structure going on top. Of course, you can see plumbing rough-ins down there. All the floors have been patched in and replaced. New stairs right here, framed and ready to go. And of course all the framing floors, everything in place up top. Waiting to receive walls, timber frame and roof components. The guys are also pre-framing some of the roof components. As you can see underneath that big orange tarp there, that's the roof. I think that goes over the master bedroom. Frame to get ready and lifted into place. So stay tuned. Looking forward to next week when we see the house come together.

Update 7 (April 6, 2021)

RDC Fine Homes' president Bob Deeks provides the seventh update on our new home renovation project in Whistler's White Gold neighbourhood. The top two floors of this renovation have been removed. We're ready to start installing wall panels created in-house to replace the top floors removed. Explore the next step of this home renovation with us!

Transcript Update 7

Bob Deeks 00:01:
Bob Deeks from RDC Fine Homes here. I am here at our Whistler Net Zero renovation. This is day one of assembling our panelized walls that we fabricated in our shop over the last five weeks. You can see we've got Black Tusk Crane set up and they've done a great job on the first day in getting the wall panels in.

Bob Deeks 00:23:
The schedule from here is they'll get the remaining walls on this main floor that you can see here. They'll get those remaining walls in. You can see the walls that are remaining sitting on the trailer here. They got about three quarters of them done today. And of course we are assembling our BASF HP plus+ wall system. As you can see from this wall right here, that grey material you can see on the outside of the wall, that is our EPS graphite-impregnated Neopor insulation. And that gives us an extra R-10 on the outside of our walls, so we can meet the performance values that we need to hit for our Net Zero label, with CHBA's Net Zero Labeling Program.

Bob Deeks 01:11:
The tape that you see that says 3M on it, I'll zoom in a little bit here. You can see that 3M tape. That taped onto our Neopor is what creates our weather-resistant barrier. So we can avoid all that messy Tyvek flapping in the breeze when it comes time to finish up our building envelope.

Bob Deeks 01:33:
So stay tuned over the next three or four days. And by Thursday afternoon, late in the day, I suspect, we'll have a roof on my left hand side here, and then over what you can see on this side, which is the kitchen, living room, dining room.  We've got a timber package coming from FraserWood Industries in Squamish. That timber package is still about 10 days to two weeks out. But when that gets installed, we will have completed the framing on this fantastic renovation.

Bob Deeks 02:07:
So stay tuned. Updates to follow. And of course, if you want to follow along on this exciting project. Be sure to subscribe to the YouTube channel or follow us along on Facebook and Instagram. Thanks.

Update 8 (April 13, 2021)

RDC Fine Homes' president Bob Deeks provides the seventh update on our new home renovation project in Whistler's White Gold neighbourhood. Bob takes us on a tour of the ground floor plus the two nearly built top floors. These floors were constructed using prebuilt wall and floor panels which we craned into place. Explore the next step of this Whistler home renovation with us!

Transcript Update 8

Bob Deeks (00:00):
Hey, Bob Deeks here with RDC Fine Homes up in beautiful Whistler, British Columbia. Just watching block toss cranes pull out after completing the assembly of our prefabbed Net Zero Ready home here. They just put on the third-floor walls, you can see sitting up there and these two prefabricated roof assemblies. So the boys have been working away for the better part of a week to put this structure together. A week today, we will see our timber frame package come in for that last remaining section of roof that you can see missing in the middle and some canopy roofs over the garage and the front entry. Let's go inside quickly, and we'll do a quick run-through inside so you can see the progress to date. So lower floor framing is all complete. This was done while the prefabbed walls were being done. You can see everything in place, including some plumbing rough-ins hiding in the background there. All the plumbing rough-ins are also done down on this lower floor, getting ready for when we get the roof on, and we can complete our electrical and plumbing and mechanical rough-ins.

Bob Deeks (01:24):
You can see that's the floor pack above for the master bedroom wing. A few interior walls left to go in. Beautiful view out the back, and we can see with the glare of the sun under the creek down below there. And then we've got some temporary stairs in here. These stairs will eventually get replaced with a steel and wood tread assembly, and we'll go up and have a look at what the master bedroom level looks like. The roof is on. Pretty cool. The master bedroom with an awesome view up to where the black home up in the background there down over the creek. A little balcony that'll go over the top of the room that you see down below here. So looking forward to our timber frame package over the kitchen, living room, dining room here, which, as I said, comes in next week, and we will have a home with a roof. So stay tuned and make sure to subscribe to the YouTube channel here if you want to follow along or follow us on Facebook and Instagram. Thanks for watching.

Transcript Update 9

Bob Deeks (00:00):
Hey there. Bob Deeks with RDC Fine Homes back here at our Net Zero Renovation in beautiful Whistler, British Columbia. As you can see, the crane is getting set up. Thanks and a big shout-out to Black Tusk Cranes for all the work they've done to assemble this prefabricated renovation here. We are just waiting the delivery of our prefabricated glulam timberframe from FraserWood Industries down at Squamish. So just a brief shot here this morning to see how things are getting set up, and then I will come back this afternoon, and we will have a look at the progress that the boys have made in prefabricating this fabulous timberframe structure. So stay tuned, and we'll be back this afternoon.

Bob Deeks (01:24):
Bob Deeks here. I am back at our Whistler Net Zero Renovation. We were here this morning. Crane was getting set up to install our prefabricated glulam timberframe package. So it is about 4:30 PM. FraserWood has been here for the day, and as you can see, we have a transformational impact on the look of the house. That glulam timberframe is nearing completion. You can see the main large purlins and the small rafters that are spaced in between. Eventually, there will be a similar detail over the front door, which is that gap underneath the RDC banner, and we'll have a similar timberframe canopy roof over the front of the garage there. So we are getting very, very close to getting the whole building closed in.

UPDATE 10 (MAY 26, 2021)

RDC Fine Homes' president Bob Deeks provides the tenth update on our new home renovation project in Whistler's White Gold neighbourhood. Bob walks through the home construction tactics used to create this Net Zero Ready luxury home renovation! 

Transcript Update 10

Bob Deeks (00:00):
Bob Deeks from RDC Fine Homes. And I am standing out in front of our net zero renovation here in beautiful Whistler, British Columbia. If you don't know what a net zero renovation is, it is a house that is being renovated so that it can produce as much energy as it uses through the solar panels that are going to go on its roof, when the project is nearly complete. For those of you who don't know RDC Fine Homes, we are a leader in energy efficient, sustainable residential luxury construction here in Whistler, British Columbia, working Pemberton, Whistler, Squamish, and all the way down to the north shore through west Vancouver, North Vancouver. And we are very excited to be working on our second net zero renovation here in Whistler. So let's go on inside and I'll show you the progress to date. And we'll talk a little bit about what's to come.

Bob Deeks (00:55):
We're going in from the garage, into the new mudroom on the lower floor. As you can see, framing is generally complete down here. Plumbers have been working on the rough-ins last week. We are about three weeks away from getting our windows and moving on to insulation. Great shot of the backyard out there, creek and beyond the gate. Really lovely private spot here. Very, very close to the ski hill, actually in the village. It's about a 15 minute walk from this location into the Whistler Village.

Bob Deeks (01:31):
Let's go on upstairs, and we'll have a look at the main kitchen, living room, dining room floor. Some exciting developments over the last week or so. This area is going to be bedrooms and bathrooms. But in here, the boys are just finishing the structural tongue and groove ceiling that you can see, on this fabulous prefabricated glulam timber frame structure that makes up the ceiling of the kitchen, living room, dining room. big shutout to FraserWood Industries for doing all the prefab work on the timber frame there. So as you can see, a nice, big, open space. And what you see up top, is all new. The shot that we saw down below, that is all the original structure. So we kept the foundation, we kept all the bottom floor framing. And we have framed everything above as new, which is not only really transforming the house, but it has an enormous savings on the embodied carbon of construction here as well. And we'll talk a little bit more about that later on in a few future posts. Let's quickly go on upstairs and have a look at the view from the master bedroom.

Bob Deeks (02:45):
Really awesome view here of the creek that runs in behind the house. And as you can see, as I pan over, that's Whistler Mountain in behind the trees there. And as we come over this way over the roof of the house, just in behind the trees, that's Blackcomb Mountain.

Bob Deeks (03:00):
As you can see down here, another new house being built. Somewhat of a similar strategy. They're using insulation on the outside of the building to improve their wall performance, much in the same way that we're using here. We're using a similar material, but this material here has got graphite impregnated in it. So we actually get about a 25% bump on the installation value per inch with the black EPS, as opposed to the white EPS they're using next door. So similar strategies, just a little bit better performance in our wall here. And in a later post, we will talk a little bit about what those installation strategies are, both in the walls and the ceiling that help get us to a place where we could produce as much energy as we use when we go to put our solar panels on the roof. Then that's what makes us a Net Zero home.

Bob Deeks (03:54):
Alright, well stay tuned for future updates. And if you want to get posts on those, then make sure you subscribe to our YouTube channel or follow us along on Facebook and Twitter. Thanks.

UPDATE 11 (JULY 5, 2021)

RDC Fine Homes' president Bob Deeks provides an update on our new home renovation project in Whistler's White Gold neighbourhood. Bob review the Aerobarrier testing by Airtight Solutions to help determine gaps and leaks for this home renovation. By filling in gaps and leaks this work helps us achieve a Net Zero Ready home construction rating.

Transcript Update 11

Bob Deeks: (00:00)
Hey there, Bob Deeks with RDC Fine Homes. I am back at our Net Zero renovation here in beautiful Whistler, British Columbia. A pretty exciting day for us here today at this groundbreaking project where we're going to take an older Whistler home, renovate it, and convert it to a Net Zero, meaning that it can produce as much energy as it uses once we're finished. We are two or three days away from drywall and today we've got Airtight Solutions here that is going to install the AeroBarrier Air Tightness System.

Bob Deeks: (00:37)
We'll go on inside and have a look at the prep work that's underway. This is an atomized sealant that gets installed under pressure within the house. It'll find all the gaps in our exterior building envelope and make sure that we get down to our 1.5 air changes to meet the air tightness requirements for our Net Aero label with the CHBA Net Zero Labeling Program. Let's go on inside and see how the guys are making out with their prep work.

Bob Deeks: (01:08)
The guys are finishing up here prepping the window. You can see that blue film on the bottom of the window track, that's just to make sure that none of the AeroBarrier sealant collects on the bottom of the window track. All the green tape there is to seal the opening doors to make sure we don't get sealant where we don't need it. You can see they've taped the track up on top there as well just to protect the door, to make sure we don't get sealant where we don't want it.

Bob Deeks: (01:37)
Then you can see up in the corner here. What's really important is any large gaps that we see in framing. We want to make sure those are sealed so they've done a little spray foam. There was a big gap there. Then you can see they've just caulked this long, vertical seam in the framing. The one place that we know is a little bit susceptible to air leakage or these long linear gaps. We're just going to go around and pre-seal those before we start our spray.

Bob Deeks: (02:03)
You can note the backer rod and then the caulking. The white caulking that you can see here. That gives us a really nice airtight seal between our doors and our windows. We only seal our doors and windows to the inside, we leave the cavity to the outside open just to make sure that if there's any moisture that gets in it can always get out.

Bob Deeks: (02:25)
There we go. Prep well underway here. You can see they're starting to spread out the hoses and set up the spray guns inside. They're a couple hours still away from starting their spray, and we'll be back this afternoon to watch the spray in progress. Of course, our target here is to get down under 1.5 air changes. That may not mean much to everyone but that's just an indication of how tight the building is. You can see the guys in the background just laying down some plastic to protect the floor so it's not a sticky mess after we finish spraying here.
