There is a stretch in a renovation when sealing the whole house is simplest, and it is before the flooring and cabinets go in. After that it still works, with more masking. One day on site, and before we leave you watch the leakage drop on a blower door.
You'll talk to the owner, usually same day. Not a call centre.
Where is your renovation right now?
One tap. I will tell you whether we can still get in, and on most stages work out the last day you can call.
Your renovation runs in a fixed order. Find where you are on it below, and you will know how simple the seal will be.
Best here. Nothing is covering the gaps yet, so the sealant gets straight to them.
Tap a step above, or a stage in the hero, and I will tell you where you stand.
Demo or framing
The whole window is still ahead of you, which is the best place to be. Before we can seal we need the windows and exterior doors in so the house can be closed up and put under pressure, and the rough-ins finished and inspected so nobody drills back through the seal. You are not booking today. What is worth knowing today is the last day you can call me, because that date arrives sooner than people expect.
When are the flooring or the cabinets booked?
Rough-ins going in
Once the rough-ins are inspected and the insulation goes in, you are at the best point in the whole job. Nothing is covering the gaps yet, so the sealant gets straight to them and the day goes quicker. Work out your call-by date below so it does not get away from you, then call me and we will price it on your house.

Insulation in
Cavities filled, nothing covering the gaps. If your windows and exterior doors are in and the rough-ins are signed off, we can seal this house. One day on site, and before we leave you watch the leakage come down on a blower door and you keep the report with the final number on it. This is the call to make today.
When are the flooring or the cabinets booked?
Drywall up
Drywall up is not too late. It is harder for the sealant to reach the gaps with the board on, so the day takes a little longer, but the leakage still comes down. The photo further down is a real seal running in a house with the drywall already hung. The finished materials, flooring and cabinets and trim, do not end it either. They just mean more masking. Call me before they go in if you can.
When are the flooring or the cabinets booked?
Taped or primed
We can seal after the taping and after the prime coat. It works. Once the finished materials go in it still works, but it needs a full masking plan and costs more, so if your flooring or your cabinets are booked, that date is the one that matters now. Work it out below, then call me, because at this stage it is usually a question of which week rather than whether.

Finishes in
Finished floors and cabinets do not rule it out. They get masked before the seal, so the day runs longer and the masking is quoted on top of the seal. We still work a whole house or a whole floor, so tell me which rooms are finished and you will have a straight answer and a number on the phone.
If the house is finished, the envelope seal still works with masking, and duct sealing is a separate job that also works. Duct sealing →
Once the finishes are in, the seal still works. It just takes more masking and a longer day.
Not sure where you land on this? Call me and I will tell you in two minutes.
Here are the five things we check. If your job clears them, call me. If it does not, I will tell you on the phone instead of booking a visit you do not need.
Less smoky valley air sneaking in through the gaps, so more of the air in the house arrives through your furnace filter.
A tighter shell holds the temperature you set instead of fighting the leaks.
Sound leaks through the same gaps air does. Closing them is one of the things that makes a house quieter.
The same small cracks let in all three. Closing them now costs less than at any later stage.
CleanBC · not for sealing alone There is no BC rebate for air sealing on its own. But if your renovation also includes three or more bonus-eligible upgrades like insulation, heating or windows, sealing improves your EnerGuide rating and can help you qualify for CleanBC’s Home Energy Improvement Bonus. Ask me on the call.
Seb sealed our house really well. We live in a heritage house and needed to decommission the heaters, our only source of heat is a gas fireplace. After he made the seal, blocking all the leaky parts of the place, it’s made a huge difference.
Seems to work really well. It’s remarkable how much it helps, it’s so much less drafty in our old house now.
I was the first home in the Kelowna area to benefit from the new AeroBarrier sealing technology. My 6,000 sqft residence has been remarkably efficient to heat and cool. My home currently exceeds the future code.
Fantastic communication, professional workmanship, and great results. Planning to work with Sebastian and crew more and more as we move toward more energy efficient homes.
Send us the address and what stage the job is at, and we will come back with a price and a straight answer on whether it is worth doing. If the timing is wrong I will say so. You talk to the owner who runs every seal, usually same day.
No. We can still seal after the drywall goes on, and even after the prime coat. We would rather be there before the taping, because with the seams still open the sealant gets to the leakage points more easily and the day goes quicker. Even after the flooring and cabinets go in it can still be done, with more masking and a longer day. So the earlier you call, the simpler it is.
Most renovations start at $4,200. The number moves with square footage, how much existing finish has to be protected, and access, so we quote it on your house rather than off a table. You get the price before we book anything, and I would rather tell you on the phone that your job is not worth doing than sell you a compromise.
By one day, and not even a full one for your trades. The house has to be empty while the seal is running, so nothing else happens on site while we are working. Once the house has been ventilated you are back in the same day, or the next morning at the latest, so your next trade can pick up the same afternoon or the next morning, whichever suits the schedule you already have.
Not for air sealing on its own. BC does not pay for it as a line item. But a tighter house improves your EnerGuide rating, which can qualify you for CleanBC’s Home Energy Improvement Bonus once you pair it with three or more bonus-eligible upgrades like insulation, heating or windows. Sealing makes the rest of your rebates go further.
No. Build tight, ventilate right. Seal the leaks you cannot control, then bring fresh air in on purpose through a ventilation unit you control, an HRV or an ERV. A tight house with good ventilation is healthier than a leaky one, not stuffier.
It is a water-based acrylic. It dries in place, it is inert, and once the house has been ventilated you are back in the same day, or the next morning at the latest. The crew wears respirators while spraying, which is why nobody else is in the house while it runs.
