Noticing Signs of Water Intrusion?

Small leaks become big problems—and most go unnoticed until damage is done

Water Stains After Rain

Discoloration on walls or ceilings near windows means water is getting in. Every storm makes it worse, and mold may already be growing behind the drywall.

Rotting Wood & Bubbling Paint

Soft spots around window frames, peeling paint, or swollen trim are signs of ongoing water damage. The longer you wait, the more expensive the repair.

Bugs & Critters Getting In

Those gaps around windows and doors aren't just letting in air—they're an open invitation for insects, spiders, and critters to make themselves at home inside yours.

Drafts & Energy Loss

Failed seals don't just let water in—they let conditioned air out. You're paying to heat and cool the neighborhood while your home stays uncomfortable.
