Closed-cell spray foam in Kelowna and the Central Okanagan

EcoSeal Building Performance Systems is based in Kelowna and works across the Central Okanagan and the wider BC Interior. We do closed-cell spray polyurethane foam on attics, walls, crawlspaces, and full new builds. We do not do residential renovations where one room of a batt-and-poly house gets foam. That does not deliver the airtightness benefit and we will tell you so.

What you get

Two-pound closed-cell spray foam at around 6.2 R per inch (LTTR), CAN/ULC certified, applied to manufacturer-spec density and pressure. A continuous air barrier that doubles as the vapour retarder where the assembly calls for it. Density and moisture checks before the gun runs. A written declaration of what was actually installed, useful for your Step Code energy advisor and useful at resale.

When spray foam is the right call in Kelowna

New construction, where we can spray before drywall and reach every cavity. Crawlspace walls and rim joists, where stopping air movement also stops cold floors. Attic floors and roof decks on existing homes, where a thermal break across the joists can finally make the bedrooms upstairs comfortable.

When it is not

A single room added to a batt-and-poly house. A renovation where the substrate is wet. A condo or strata building (we don't work those). Any project where the homeowner wants the cheapest option. We are not that.

3

We show up on schedule.

We do the job right and we never hold up another trade.

Straight talk

When not to hire us.

We will tell you straight when spray foam is not the right call. A single room of foam in a batt and poly house will not give you the airtightness benefit. The air just finds the next gap. When a smaller job makes more sense we will say so. That is the whole point of the free building assessment.

Frequently asked questions

How much does spray foam insulation cost in Kelowna?
We price by board foot. Closed-cell spray foam in Kelowna runs around $1.80 per board foot for residential and small commercial work, with the range moving with project size and access. We give a written quote after we see the building. We do not quote sight unseen.
Is spray foam safe? Does it off-gas?
Closed-cell SPF is CAN/ULC certified. The chemical reaction completes in seconds. Once cured the foam is inert. The off-gassing rumour has been around longer than the foam has been on the market. We have heard it enough times that we have stopped being surprised.
Will spray foam pay for itself in a Kelowna home?
Energy savings on a single home are real but modest. The bigger argument is comfort, airtightness, and not having to redo the work later. If you are weighing batt versus foam on a renovation where the rest of the house stays batt and poly, foam in one area will not give you the airtightness benefit. We will tell you when the math does not work.
Do you spray over wet substrates?
No. Spray foam over moisture fails. It does not adhere properly and the problem stays hidden until it is expensive. We test for moisture before every application. We have walked away from jobs where the substrate was wet.
Can spray foam help with a Step Code home in Kelowna?
Yes. SPF acts as a continuous air barrier and gives about 6.2 R per inch (closed-cell). For Part 9 homes targeting Step 3 or higher, the airtightness contribution alone moves the model meaningfully.
