When you notice a stain or a musty corner, the first question is often about mold. The next question matters just as much: where is the moisture coming from?
Look for the pattern
A plumbing leak, water entering around the building, and condensation can leave similar clues. Notice whether the problem follows rain, shower use, or a recurring damp period. Share that history with your inspector.
Keep moisture in check
EPA recommends repairing leaks promptly, venting moisture-producing appliances outdoors, and keeping indoor relative humidity below 60%, ideally 30-50% when possible. A humidity reading can help you spot a pattern, but it does not diagnose the whole building.
If moisture keeps returning, arrange an investigation. At North Sound, the aim is to understand the conditions before recommending the next step.
A useful first conversation
Tell us where the issue appears, how long it has been there, and what changes it. Photos and a brief history of previous leaks give that conversation a useful starting point.
