Frequently Asked Questions

What causes window leaks?

Window leaks are commonly caused by deteriorated sealants, damaged flashing, improper installation, aging building materials, or failures in the building envelope.

Can leaking windows be repaired without replacing the window?

Yes. In many cases, the issue can be resolved by repairing flashing, replacing sealants, or correcting deficiencies around the window rather than replacing the entire window.

How quickly should I repair a leaking window?

As soon as possible. Even small leaks can cause hidden moisture damage, mold growth, and deterioration of structural materials over time.
