Frequently Asked Questions

What areas do you typically seal?

We focus on "penetrations" in the building envelope. This includes gaps around outdoor faucets, dryer vents, cable TV lines entering the house, and electrical outlets on exterior walls.

Do you insulate electrical outlets?

Yes. Outlets on exterior walls are a major source of cold drafts. We install specialized foam gaskets behind the faceplate and use child-safe plugs to stop air from whistling through.

Can this prevent pipes from freezing?

Indirectly, yes. By sealing the gaps where cold air hits your pipes (especially in basements or under sinks), we reduce the risk of localized freezing during extreme cold snaps.

Requires inspection: Yes
Estimated Time: 1 to 4 hours

Service Complexity Basic

Why is a Technical Visit necessary?

Small leaks add up. The cumulative effect of tiny gaps around electrical outlets, baseboards, and pipe penetrations can be equivalent to leaving a window open all winter. However, using the wrong sealant (like high-expansion foam around windows) can warp frames. Our Minor Weatherproofing assessment identifies these hidden air leaks and selects the appropriate material—whether it's caulk, foam gaskets, or spray foam—to seal them safely without damaging your finishes.
