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.

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 missed rebateUp to $20,000 a unit from FortisBC left on the table when the target slips.
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 certify
You watch the ACH50 fall in real time and I seal to your target. You leave with a blower-door certificate 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 certificate
Typically one controlled day on site, one measured number, one certificate for your file. A tighter envelope means fewer draft and cold-spot callbacks after handover.
Unlocks the rebate
Hitting the Step 4 and 5 targets depends on a tight envelope, so a measured seal helps unlock FortisBC’s higher-step rebates rather than adding cost. Confirm amounts with FortisBC.
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
Step 4 expected as BC’s new-home minimumExpected around 2027. The exact date can still move; the direction has been signalled by the Province.
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 4 is widely expected to become BC’s minimum for new homes around 2027.
FortisBC’s New Home Program offers builders up to $15,000 a unit at Step 4 and up to $20,000 at Step 5, through an electrification pathway (air-source heat pump plus electric hot water). A Design Offer adds up to $7,000 per home toward early envelope and mechanical consulting. Confirm current amounts and eligibility with FortisBC.

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.
Google
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 $3,700 for a typical home.
Final price depends on the home size and your target ACH50. It is one measured day on site, and on a qualifying build the FortisBC rebate can cover most of it. 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 missed rebate. A measured seal is the cheap insurance, not the premium add-on.

Common questions
What does it cost?
Air sealing starts at $3,700 for a typical single-family home and scales with home size and your target ACH50. It is one measured day on site, and on a qualifying build the FortisBC rebate can cover most of it. 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 the blower-door certificate. 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.
How do the FortisBC rebates work?
FortisBC’s New Home Program pays up to $15,000 a unit at Step 4 and up to $20,000 at Step 5 through an electrification pathway, plus up to $7,000 per home for design and envelope consulting. Hitting those steps depends on a tight envelope, so a seal helps unlock them. Confirm current amounts with FortisBC.
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 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.
