Seattle Window Repair Contractor

If there’s one thing that homeowners in Seattle have in common, it’s that they all have to deal with the effect of the notoriously-damp Pacific Northwest climate on their homes. Wet weather can lead to all sorts of problems, including those pesky window leaks. Leaking windows are sometimes difficult to spot early on, as the signs aren’t always as obvious as a drip or a puddle. Sometimes they’re more subtle, like a water stain on sills, jambs, and the drywall surrounding the window. Other signs include mold, musty odors, rotten or swollen trim, or dark streaking behind the window.

Long-Lasting Window Repair

Repairing window leaks promptly is important because an minor leak can lead to more serious problems if ignored. Once moisture penetrates the protective barrier, the underlying wood and structure is susceptible to developing rot. And once rot takes hold, it tends to spread, potentially leading to major damage as well as a major expense!
