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

Computer-controlled air sealing for Okanagan builders. We measure the leakage live and stop at your ACH50 target, so you know the number before your energy advisor tests. One day on site, run by the owner, not a call centre.
You'll talk to the owner who runs every seal, not a call centre. Usually same day.
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.

A few of the Okanagan builders and developers we’ve sealed for.





















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. We bring the leakage down on purpose and you watch the ACH50 fall in real time, so you know the build passed before we leave the site.

We bring in the sealing rig and protect the finishes and openings. AeroBarrier works best pre-drywall, at framing, but finish-grade masking lets us seal late-stage rescues too.

A blower door brings the home to a controlled pressure, exposing every leakage path in the envelope at once.

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.

You watch the ACH50 fall in real time and we seal to your target. You leave with an Airtightness Verification Report documenting the result.
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.
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. We test first and tell you straight.
Best value pre-drywall. Late-stage and occupied-home retrofits are routine too, they just need a more detailed masking plan.
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.

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.
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.
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.
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.

“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.”
Final price depends on the home size and your target ACH50. It is one measured day on site. No mystery quotes. Tell us the project and we’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.
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 us the project and we’ll give you a real number.
That is the whole point. We 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.
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.
Often, yes. A measured seal reaches the diffuse leaks that are hard to chase by hand, frequently without tearing back finished work. We test first and tell you straight whether a seal will get you there.
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.
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.
We serve the Okanagan Valley: Kelowna, West Kelowna, Lake Country, Vernon, Penticton, Summerland, Peachland, Coldstream, Salmon Arm and the surrounding communities.
Our crew, with Sebastian, the owner, running the seal. You deal with the person who runs the seal, not a call centre or an account manager three provinces away.
