Why it matters

Water gets in through the cracks and can damage the chimney, cause leaks and break down the masonry.

How common is it?

Found in 10% 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.
