Air Sealing in Penticton

Air sealing is the process of identifying and closing gaps, cracks, and openings in your home's building envelope that allow conditioned air to escape and outside air to enter. Even a well-insulated home will underperform if air is leaking around it. Air sealing is the foundation that makes your insulation work as intended.

The biggest air leaks are typically found at the attic hatch or pull-down stairs, around plumbing and electrical penetrations through the ceiling, at recessed light fixtures, where interior walls meet the attic floor (top plates), around ductwork penetrations, and at rim joists in the basement or crawlspace. Many of these leaks are hidden and only detectable through a blower door test.

Always before. Air sealing must be done before insulation is installed (or after old insulation is removed) because most air leakage points are hidden beneath or behind insulation. Insulating over unsealed gaps is like putting on a sweater with holes in it — you'll still feel the draft. That's why we always include air sealing as part of our attic insulation upgrades.
