What Causes Wet Basements for Portland, OR Buildings

Most water problems begin small and grow slowly over several wet seasons. A hairline crack in the floor slab can be the first sign that groundwater is finding a way in. Across Portland, OR property managers, ignoring these signals only allows mold and rot to spread.

You should also watch for horizontal or stair-step cracks, seepage where the wall meets the floor, and soft or swollen drywall. When these signs appear, it is time to call a professional, since a correct diagnosis is the foundation of every lasting repair.
