Leaking Basement Windows

Ignoring a leaking window in your basement is never a good idea. Mold, high humidity, and musty smells are just some of the problems you’ll experience if water enters the basement. Over time, accumulated water puts pressure on your foundation, weakening your home’s structural elements.

For true peace of mind, identify the cause of leaking windows, seal water entry points, and install waterproofing solutions with the help of a professional. Matvey Foundation Repair permanently removes and prevents basement moisture for homeowners across Seattle and Western Washington.

Leaking Basement Windows FAQs

When basement windows leak, you’ll experience mold, musty smells, efflorescence, high humidity, or damp walls. Waterproofing your basement or crawl space resolves these problems.

Costs depend on the extent of damage and the type of waterproofing solutions you need. Matvey Foundation Repair offers free estimates and flexible financing options.
