Mold on a wall may be a patch on the paint or growth that has spread through the drywall and the cavity behind it. Mold Removal Cleveland removes mold from walls in homes in Cleveland, Ohio. This page covers how wall mold is judged, why painting over it does not work and how a wall is opened, cleaned and dried.

Wall Mold Removal: what’s included in the job

Moisture readings along the wall and on the other side of it.
Opening of the wall where growth or damp is suspected.
Removal and bagging of drywall and insulation that cannot be saved.
Cleaning of studs and other framing.
Drying of the cavity.
A note on the leak, condensation or pipe that caused it.

For background, see drywall, the material most interior walls are made of.

What is behind the paint

Drywall is paper-faced, and paper is food for mold. Once water gets into a wall from a pipe, a window or a roof leak, growth can spread behind the surface before any stain appears. The CDC page on mold lists drywall among the materials mold grows on.

The EPA guide to mold cleanup in your home says not to paint or caulk over moldy surfaces. Paint seals the mold in, and the stain often bleeds through again.

Clues that a wall is wet inside

Bubbling or peeling paint, a stain that grows or comes back, a musty smell near a wall and a wall that feels cool or damp to the touch are the usual signs. A stain below a bathroom, a laundry or a window is worth checking first, because that is where leaks and condensation tend to be.

Opening and drying a mold-affected wall

Mapping the damp

A moisture meter is run across the wall and the ones beside it. This shows how far the problem reaches before any cutting starts.

A controlled opening

The wall is cut open inside containment. The crew looks at the back of the drywall, the insulation and the studs.

Taking out the affected sections

Moldy drywall and insulation are removed in pieces and bagged. Studs are cleaned and left open to dry.

Handing back a dry wall

The cavity stays open until readings are low. Closing it up and repainting are done afterward, by the business or by another trade. The crew follows ANSI/IICRC S520, the standard that guides professional mold remediation.

A stain or a soft spot on a wall? Call (216) 405-2515. The line is open around the clock.

Living with mold in a wall

The CDC says people with asthma or mold allergies may have severe reactions and that people with weak immune systems or chronic lung disease can get lung infections. Others may notice nothing. Where someone in the home is in a sensitive group, wall mold deserves early attention.

A wall opened for mold is not finished when the mold is gone. Drywall, insulation and paint still have to go back, and the cavity should be dry first. Ask who handles the rebuild so it is not left half done.

Wall Mold Removal Cleveland: questions and answers

How much does it cost to remove mold from walls?

The cost depends on how much wall is affected, whether it is open or hidden and what caused it. No honest figure can be given without seeing the wall, so the price is set after a visit and explained before work begins.

What kills mold permanently in walls?

Nothing kills it permanently if the damp remains. The growth is removed, the materials that cannot be saved are replaced and the moisture source is fixed. Dry material does not support mold growth.

Can you live in a house with mold in the walls?

Some people notice nothing and others react strongly. The CDC says people with asthma, allergies, weak immune systems or chronic lung disease are more at risk, so it is best not to leave it.
