Air Sealing
Done Right
We don't just seal gaps and hope for the best. Every job starts and ends with a blower door test, so you get sealing that's measured, not guessed at.
Air Sealing Done Right
Air sealing closes the cracks, gaps, and penetrations in your home's envelope — the spots where conditioned air actually escapes and outside air gets in. We don't just seal and hope for the best: every job is measured with a blower door test before and after, so the results are verified, not guessed at.
Find The Leaks
We start with a blower door test, which pinpoints exactly where and how much air your home is losing before any work begins.
Seal Them Up
With the leaks identified, we seal them so the air you pay to heat and cool stays where it belongs — inside your home.
Retest To Confirm
We run the blower door test a second time to verify the sealing actually worked, not just assume that it did.
How to identify your home needs air sealing.
-
Noticeable draftsYou can feel air movement near outlets, baseboards, windows, or doors.
-
Inconsistent room temperaturesSome rooms are hard to keep comfortable no matter how the thermostat is set.
-
Higher than expected billsYour heating and cooling costs feel out of line with your home's size.
-
Dust or outside odorsYou notice dust, smells, or noise that seem to come through walls or floors.
-
Pests finding their way inBugs or rodents are getting inside through gaps you can't see.
-
Visible daylightYou can see daylight around an exterior door or window frame from inside.
The real benefits of a properly sealed home.
-
Insulation that finally works as intendedAir sealing is what lets your insulation actually do its job — without it, conditioned air slips through the gaps no matter how much insulation is up there.
-
Lower bills, longer-lasting equipmentYour furnace and AC don't have to run as hard to keep up, which means lower monthly bills and equipment that lasts longer before it needs replacing.
-
Less dust, less cleaningFewer gaps means less outside dust and debris getting pulled into your home, so there's less settling on your floors, furniture, and vents.
-
More consistent temperaturesNo more hot upstairs bedrooms or cold spots by the front door — every room stays closer to the temperature you actually set.
-
A true separation between living and non-living spaceYour attic, crawlspace, and garage stop sharing air with the rooms you actually live in.
An unsealed attic can affect the air you breathe.
Your attic isn't as separate from your living space as it looks. Gaps around recessed lights, plumbing stacks, chimneys, and attic hatches create a direct pathway for attic air — carrying dust, insulation particles, and other contaminants — to be pulled down into the rooms you live in as your home heats and cools. Air sealing closes that pathway.
-
Keeps attic air out of your living spaceCloses the gaps that let attic dust, insulation fibers, and allergens drift down into the rooms you spend time in.
-
Cuts off a pathway for pestsThe same gaps that let air through are often how pests — and what they leave behind — get inside.
-
Stops uncontrolled air movementReduces the unwanted odors and pollutants that uncontrolled airflow can pull into your home.
Air sealing isn't just about comfort and cost — it's about what's actually in the air your family breathes every day.
How Much Air Are We Talking About?
The average person breathes in roughly 11,000 liters of air a day — about 2,000 gallons, or enough to fill a backyard swimming pool. What's actually in your home's air adds up fast.
