Frequently Asked Questions
Does drying the area solve the problem?
Not necessarily. The source and damaged materials must be evaluated.
Can a seller say the leak was repaired and disclose nothing else?
Material repair history may still matter. The seller should obtain professional guidance.
Does an inspector always find old water damage?
No. Repairs, finishes and inaccessible areas can hide evidence.
Water damage is not one single issue. Buyers should understand what happened, what was repaired and whether the cause may recur.
