Mold Remediation Cost in Maryland: What Homeowners Actually Pay (2026 Guide)
By Ohio Mold Testing Inspections · Updated 2026-09-13
The first question every homeowner asks is how much does mold remediation cost. The honest answer is that it depends on square footage, what the mold is growing on, whether the area is still wet, and how much material has to come out. Here is how the numbers typically break down across Maryland, from Baltimore to Salisbury.
Typical mold remediation price ranges
- Small contained area (under 10 sq ft) such as a bathroom corner or window sill: often a few hundred dollars, sometimes handled during a mold inspection visit.
- Single room or wall cavity (bathroom, laundry, closet): low to mid thousands, including containment, removal of drywall and HEPA cleaning.
- Basement or crawl space: mid thousands and up depending on size, framing exposure and whether encapsulation or drying is needed. See basement mold removal.
- Attic mold remediation: priced by roof deck area; usually includes correcting ventilation.
- Whole-house after flooding: the largest jobs, often combined with water damage restoration and rebuild.
What makes the cost go up
Hidden mold behind finished walls, mold inside HVAC systems, ongoing leaks, contaminated insulation, and the need for rebuild after removal are the big multipliers. Black mold (Stachybotrys) does not cost more per square foot to remove, but it is usually found in areas that have been wet for a long time, so those jobs tend to be bigger.
