HOMEOWNER ADVICE

Air sealing and insulation work together

Two different parts of a home comfort plan.

Insulation slows heat transfer through the building enclosure. Air sealing addresses gaps and openings that allow air to move between spaces. A drafty room can involve more than one part of the house, so the location of the symptom alone may not identify the full scope. Share when the discomfort happens and whether wind or outdoor temperature changes it.

An assessment can help connect visible gaps, existing insulation, and the way the home is ventilated. Ask which leakage paths are included and how the work relates to nearby insulation. A clear proposal identifies the work areas and preparation. It should also explain any follow-up checks included in the project.
