About air sealing
Air sealing addresses the gaps and penetrations that let conditioned air escape. It is often paired with insulation upgrades for the biggest comfort gains.
Who air sealing is for
Any homeowner whose drafts, HVAC costs, or comfort issues weren't fully solved by insulation alone.

A dedicated whole-home air-sealing project typically runs 1 day; bundled with insulation, it adds a few hours.
