Mold Remediation · What To Do Now
There’s Mold on My Walls — What Do I Do?
Mold on a wall usually means moisture is getting into it — from a leak, condensation, or humidity. Surface mold on drywall can also mean more growth inside the cavity.

Work through these in order — the first few minutes decide how much damage spreads.
- 1
Find the moisture source: a plumbing leak, roof/window leak, condensation, or high humidity.
- 2
Isolate the room and turn off HVAC to limit spread.
- 3
Don’t disturb the mold or cut into the wall yourself.
- 4
Lower humidity and fix the water source.
- 5
Photograph the affected walls and note the size of the area.
Careful
What to Avoid
-
Don't paint over it (even ‘mold-killing’ paint) — it grows through.
-
Don't scrub drywall mold with bleach — porous drywall usually can’t be saved and scrubbing spreads spores.
-
Don't open the wall without containment — you release spores into the home.
When to Call a Pro
Because drywall is porous, wall mold usually means removing the affected material under containment, drying the cavity, and treating the framing. Binnacle does this to S520 standards and verifies it’s clear.
Common Questions
There’s Mold on My Walls
Can mold on drywall be cleaned, or does it have to be removed?
Because drywall is porous, moldy drywall typically has to be cut out and replaced rather than cleaned — surface cleaning leaves growth inside the material.
Is there mold inside my wall if it’s on the surface?
Often yes — the visible mold is fed by moisture in the cavity, so there’s frequently growth on the back of the drywall and the framing too.
