By resealing every 5–8 years (or whenever caulk becomes brittle or pulls away), you’ll extend your windows’ life and keep your home comfortable year-round.

If you see fog or droplets inside the glass, the vacuum seal on the Insulated Glass Unit (IGU) has failed. The argon or krypton gas has escaped.

Resealing a window is a high-ROI maintenance task. It lowers energy bills, stops drafts, and prevents costly water damage. You’ll need about 1–3 hours per window, plus drying time.
