01
Set up and prep
I bring in the sealing rig and protect the finishes and openings. AeroBarrier works best pre-drywall, at framing, but finish-grade masking lets me seal late-stage rescues too.

FortisBC’s New Home Program ends February 28, 2027.
Book a seal before your final → FortisBC says the program is close to its budget cap and pays only on completed homes with an occupancy permit. If a Step 4 or Step 5 build is counting on it, a failed final test now puts the rebate at risk along with the schedule.

The problem
Why hand-sealing misses the number.
Hand-sealing is blind. You caulk, you tape, and you do not find out the real airtightness number until the final blower-door, when the drywall is up and your options are mostly gone.
A measured seal flips that around. I bring the leakage down on purpose and you watch the ACH50 fall in real time, so you know the build passed before I leave the site.
- A re-testBook the blower-door a second time and wait on the result all over again.
- CallbacksChase drafts and cold-spot complaints after handover, on your own dime.
- A late occupancyThe final airtightness test sits right before occupancy. Every week it slips, the buyer, the lender and your next job wait.
How it works
One day. Four steps. A number you can prove.
02
Pressurize
A blower door brings the home to a controlled pressure, exposing every leakage path in the envelope at once.
03
Seal from the inside
A computer-controlled aerosol fills the space. The mist finds the leaks and seals them. Joints, penetrations, the gaps you can’t reach by hand.
04
Measure and verify
You watch the ACH50 fall in real time and I seal to your target. You leave with an Airtightness Verification Report documenting the result.

Pass the first time
Manual sealing is blind: you caulk, you tape, and you find out the number at the final blower-door. I measure leakage live and bring it to the target on purpose.
Hit Step 4 on demand
Step 4 means 1.5 air changes per hour, down from 2.5 at Step 3. That is roughly 40% less leakage, where hand-sealing tends to come up short.
One day, one report
Typically one controlled day on site, one measured number, one verification report for your file. A tighter envelope means fewer draft and cold-spot callbacks after handover.
Keeps occupancy on schedule
The final airtightness test sits right before occupancy. With a measured seal you already know the answer when your energy advisor arrives, instead of booking a retest.
Rescue a failing test
Borderline on your blower-door? A measured seal can often bring a marginal result to the target it needs, reaching the diffuse leaks that are hard to chase by hand. I test first and tell you straight.
New build or retrofit
Best value pre-drywall. Late-stage and occupied-home retrofits are routine too, they just need a more detailed masking plan.
BC Energy Step Code
Where your build needs to land, and how I get it there.
…months out
BC’s net-zero-energy-ready target for new buildingsThe Province’s 2032 goal. Interim minimum steps and dates can move; check with your municipality when you price a job.
The BC Energy Step Code measures airtightness in air changes per hour at 50 pascals (ACH50). The blower door is not optional on any step that applies. The question is whether you find out the number while we can still act on it, or after the drywall is up. Step 3 has been the province-wide minimum for Part 9 homes since May 1, 2023, and the Province has set a path to net-zero-energy-ready new construction by 2032.
FortisBC says its New Home Program is close to its budget cap and ends February 28, 2027, paying only on completed homes with an occupancy permit (fortisbc.com, read October 8, 2026). The airtightness test does not end with it.

How AeroBarrier helps you hit the number
- We start with a baseline. A blower door test on the sealed-up building shows how leaky it is right now, before any sealant goes on.
- We seal from the inside. AeroBarrier is a water-based sealant. The building is closed up and pressurized, and the sealant is fogged in as an aerosol. It is carried to the leaks by the air moving through them and sticks around the edges until the gap is closed. That reaches small gaps that are hard to find and caulk by hand.
- You watch the leakage fall. The blower door stays running during the seal, so the airtightness reading drops live and we stop when it reaches your Step 3, 4 or 5 target.
- We verify with a blower door test. A closing blower door reading shows where the building finished, and you get an Airtightness Verification Report for your file. The compliance test for your Step Code file is run by your energy advisor, so you know the answer before they arrive.

We have had the pleasure of working with Sebastian and the team on multiple projects, and they have consistently exceeded our expectations. Professional, courteous, and always respectful of other trades.
Google
Excellent results, brought our blower-door test down from 2.8 all the way to 1.09. Sebastian is excellent to work with, nothing but good things to say about the process and the company.

They helped improve the air tightness in one of our renovations on a 2004 timberframe from 5.5 ACH to 2.2 at mid stage. Great service and results.
Google
Sebastian and crew were outstanding. Mid-construction blower door producing 2.2 ACH. Applied AeroBarrier and dropped to 0.5 ACH. That’s better than net zero. Couldn’t be happier.
Google
Highly recommend. We have used them to achieve phenomenal results sealing up our houses. In the end it saved us countless man hours and money to achieve the best air barrier possible.

Their process and system is like no other. They supported our projects in meeting our goals and exceeding our airtightness targets. These guys have the technology that is accelerating our industry.
Who you’re hiring
“I run Okanagan AeroBarrier myself, and I’m on site for the seals. I’ve sealed homes across the valley since 2019 and I measure every one, because a number you can’t verify isn’t worth much. If a seal isn’t the right call for your build, I’ll tell you straight. I’d rather lose the job than sell you something you don’t need.”

Duct sealing → Leaky ductwork too? I now seal ducts from the inside.
Aeroseal is the duct side of the same measured aerosol process. I test the duct leakage, seal it from the inside, and test again, so you see the drop on a real number. Even room temperatures, lower run-time, less dust. New builds and existing homes.
Honest pricing
Air sealing from $4,200 for a typical home.
Final price depends on the home size and your target ACH50. It is one measured day on site. No mystery quotes, no national-franchise markup. Tell me the project and I’ll give you a real number.
Compare that to a failed blower-door, a re-test, callbacks and a late occupancy. A measured seal is the cheap insurance, not the premium add-on.

Common questions
What does it cost?
Air sealing starts at $4,200 for a typical single-family home and scales with home size and your target ACH50. It is one measured day on site. Tell me the project and I’ll give you a real number.
Will it pass my Step Code blower-door?
That is the whole point. I measure the leakage live during the seal and bring it down to your target on purpose, then hand you a report documenting the result. Your energy advisor runs the compliance test. Typical results land between 0.5 and 1.2 ACH50; the best on record is 0.24.
When in the build should it happen?
Best value is pre-drywall, at framing, when the envelope is accessible. Late-stage and occupied-home retrofits are routine too, they just need a more detailed masking plan.
Can you rescue a failed blower-door?
Often, yes. A measured seal reaches the diffuse leaks that are hard to chase by hand, frequently without tearing back finished work. I test first and tell you straight whether a seal will get you there.
Is the FortisBC rebate still available?
FortisBC says its New Home Program is close to its budget cap and ends February 28, 2027, paying only on completed homes with an occupancy permit (fortisbc.com, read October 8, 2026). If your build can reach occupancy before then, sealing at mid-construction protects the rebate and the schedule. Either way, the airtightness test still applies.
Is the sealant safe once cured?
It is a water-based acrylic. Once cured it is inert and the home is occupied normally. Crews use respiratory protection during application as standard practice.
Where do you work?
I serve the Okanagan Valley: Kelowna, West Kelowna, Lake Country, Vernon, Penticton, Summerland, Peachland, Coldstream, Salmon Arm and the surrounding communities.
Who shows up?
Me. Sebastian, the owner. You deal with the person who runs the seal, not a call center or an account manager three provinces away.
