Why it matters

Efflorescence is left behind when moisture is present. Moisture intrusion may promote biological growth and compromise the ability to support the home's structure.

How common is it?

Didn't come up in the homes HomeCloud evaluated Sep 2025 to Oct 2026, but it's on our list of foundation and structure findings.

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.
