How to Seal Attic Gaps
Unsealed insulation contractor let warm summer air into the living areas below, forcing your AC to work overtime and driving up energy costs. In addition, leaky ductwork allows cooled air to escape before it can reach the living spaces, and framing gaps let water in during rain storms. This article walks you through how to seal attic cracks, wide gaps, and hatch leaks with GE’s advanced silicone sealants, making your home cooler, more comfortable, and more efficient all year round.

Most attic leaks are buried under insulation, but you can detect them by looking for patches of dark insulation. The dirt comes from dusty air leaking into the attic, filtering into the insulation and causing it to darken. You can also check for leaks by pulling back the insulation and looking for a gap at the joist. You can fill these gaps with a mixture of spray foam and caulk, depending on the type of insulation in your attic (balloon, batts, or rolls).

How to Seal Attic Gaps and Stop Energy Leaks for Good

Leaks around chimneys, vent stacks, and other roof penetrations are more common than you might think. Other problem spots include holes drilled in the roof for cable, wires, and pipes, and skylights that don’t have enough weatherproofing around them. Other common causes of leaks are clogged gutters, which can cause the roof to sag and allow water to enter through the attic; corroded flashing, which can let rain seep into attics and walls below; and sagging or missing shingles, which allow water to flow under the shingle and into the attic.
