Does mold remediation include replacing drywall?
Mold remediation usually includes removing mold-damaged drywall, because the paper face and gypsum core are porous and cannot be cleaned reliably once colonized. Replacing it is a separate rebuild step after the area is dry and verified clean. Scope should state both clearly in writing.

Why drywall is removed, not cleaned
Drywall is a gypsum core wrapped in paper, and the paper is food for mold. Once growth has taken hold in the paper or the gypsum, surface cleaning cannot reach the roots. Contaminated sections are cut out, bagged in the work area and removed so spores are not spread.
Drywall that was wet for a short time and is not colonized may sometimes be dried in place. That depends on how long it stayed wet, the kind of water and what moisture readings show. We do not decide by looking alone.
Remediation and rebuild are two stages
Remediation ends when the contaminated material is removed, the area cleaned and the cavity dry. Putting up new drywall, taping, priming and painting is the rebuild. Some companies only do the first stage. Others, including ours, can carry on to the second so the room is not left open for weeks.
If you are in a condo, bring this up early, because shared walls and the building's rules affect the access you have. See our condo mold remediation page for what to expect.
What a written scope should say
- Which walls and how much drywall will be removed
- How the area will be sealed and filtered during the work
- What will be done about insulation and other materials in the cavity
- How and when moisture readings are taken
- Whether the rebuild is included and what finish is planned
What you can do before the crew arrives
Do not scrub or sand moldy drywall, because that releases spores. Keep children and pets out of the room, close the door and, if you can, shut the vents in that room. Photograph the damage and note when and how the water got in. Our FAQ page answers other common questions about the process.
Questions to ask any contractor
Ask whether replacement is part of the price or a separate job, who does the taping and painting, and how long the area will be left open. Ask how the opening will be protected between steps, and what happens if more mold is found once the wall is opened. A clear written scope and a firm answer to those questions prevent most disputes. We provide a written scope and price after a free assessment.

Can I paint over mold on drywall?
No. Paint hides the stain but the growth continues beneath it.
Do you rebuild afterward?
Yes, we can carry on with the rebuild after the area has dried and been checked.
Will you work with my insurance company?
Yes. We work with all insurance companies and bill your insurer directly.
