Spots low on a wall
Mold at the bottom of drywall often means water got in behind the baseboard.

A musty smell, spots on a wall, mold that keeps coming back. Mold grows where moisture stays, often where you can't see it. Call the Rex mold line and get connected with an independent local pro.
Find the moisture and stop it if you can: a leak, a wet crawl space, damp air. Don't scrub, sand or dry-brush the mold, which can spread spores. Take photos, keep the room closed off, and call a local mold pro. The mold you can see is often a small part of what's behind the wall. One call connects you with an independent local pro.

Mold at the bottom of drywall often means water got in behind the baseboard.

Damp crawl spaces feed mold on joists and subfloors, and the smell rises into the house.

A slow roof or plumbing leak can grow mold above the ceiling before you see it.

Condensation around vents and air handlers can grow mold where cool air meets damp air.
Mold feeds on damp drywall, wood and dust. It spreads along the back of walls and under flooring, wherever moisture stays.


Every pro works their own way. This is what the work usually looks like.
Mold here has a few patterns. Knowing them helps you describe what you see when you call.

Damp air keeps basements and crawl spaces from drying out.
Many homes sit over a crawl space, where moisture goes unseen for weeks.
Clay holds water against the foundation after a storm.
Older ventilation and plumbing leave more places for moisture to collect.
Scrubbing can spread spores, and mold on drywall or wood usually goes deeper than it looks. If it keeps coming back, the moisture behind it is still there.
It depends on your policy and the cause. Mold from a sudden leak is often treated differently from mold that built up over time. Call your insurer, and take photos first.
Your call goes to an independent local business that handles mold in the Atlanta area. You may answer a quick question or two first so it reaches the right one. Service Pro Nation doesn't perform the work.
Ask about the license and insurance the work requires, how they'll find the moisture source, and how they price the job.
