Mold remediation and removal

The mold is removed under containment, the area is treated and cleaned and passes clearance, and if you want, the walls are put back together. The problem is gone, not painted over.

Remediation means removing mold-damaged materials and treating and cleaning the area, inside a sealed work area so spores don’t spread through the home. It only lasts if the moisture source is fixed, so we check that first and tell you if a plumber or roofer needs to come in before we start.

What’s included

  • Containment, negative air and HEPA filtration
  • Removal of affected drywall, plaster, insulation and wood
  • Treatment and cleaning of framing and surfaces
  • HEPA vacuuming and detailed cleaning
  • Independent clearance testing
  • Optional repairs: sheetrock, plaster and painting
  • Moving and protecting furniture and belongings

Done right, and by the rules

In New York, remediation over 10 square feet is done by a licensed remediator to an independent assessor’s plan. In NYC buildings with 10 or more apartments, Local Law 61 adds filing requirements. We handle both, and the HPD paperwork for violations.

What it costs

Price depends on the size of the affected area, the materials that need to come out, access, and whether you want repairs included. Larger jobs get a free in-person estimate.

Frequently asked questions

Do I need an assessment before remediation?

In New York, jobs over 10 square feet need a licensed assessor’s plan, and we arrange it. Elsewhere, an assessment is still the best way to define the scope and confirm the result.

Will insurance cover it?

Sometimes, especially after a sudden leak. We provide detailed scopes and reports for claims.

Can you fix the walls afterwards?

Yes. Repairs can be included so you’re not juggling another contractor.

Can I stay home?

Often, for contained areas. We’ll tell you what to expect for your job.

Will the mold come back?

Not if the moisture source is fixed. That’s why we look at the cause first.
