Seal Larger Gaps Around Windows & Doors Fast

If you feel strong drafts or find larger gaps around window and door frames those openings need more than caulk. Expanding foam fills and seals wider gaps, stopping air leaks at the source while improving insulation and energy efficiency.

This is the best solution for gaps too large for caulk or sealant.

Sealing these areas can make a noticeable difference in comfort right away.

Common Signs

• Strong drafts around window or door frames
• Visible gaps between framing and the wall
• Cold air coming through trim or casing
• Previous sealing attempts that did not stop airflow

Quick Fix Options

• Window & Door Foam: Low-expansion foam designed to seal gaps without warping frames
• General Purpose Foam: Fills larger gaps in rough openings and framing areas
• Foam with Applicator: Allows more controlled and precise application

Not sure which product to use? Small gaps are best sealed with caulk, while larger gaps may require foam or backer rod depending on the size and location.

Difficulty: Easy to Moderate
Time: 15–45 minutes
