Why it matters

The stains suggest previous moisture exposure. While dry now, the areas should be monitored for any recurrence.

How common is it?

Found in 6% of the homes HomeCloud evaluated, Sep 2025 to Oct 2026.

Counted by the finding's name on HomeCloud reports, so the true number can be a little higher.

How soon to fix it

HomeCloud reports list this as something to plan for rather than an emergency.
