Why Mold Repair Matters
Mold growth is one of the most common yet dangerous issues in U.S. homes. It thrives in humid, damp, or poorly ventilated spaces such as basements, attics, bathrooms, and crawl spaces. Mold is not just unpleasant — it releases spores that can cause serious health problems like respiratory infections, allergies, headaches, and asthma attacks.
From a construction standpoint, mold damages drywall, insulation, wood, and flooring. Over time, it weakens the structure of your home, leading to costly repairs. Professional mold repair ensures removal of existing mold, prevents recurrence, and restores the affected areas safely.
Mold Remediation Cost in USA
The cost of mold removal and repair varies depending on the location, severity, and size of infestation. The national average ranges between $1,500 and $6,000, but extensive contamination can exceed $15,000.
| Type of Work | Average Cost (USD) | Details |
|---|---|---|
| Small surface area (bathroom, drywall) | $500 – $1,500 | Light cleaning, disinfection, and repainting; no structural damage. |
| Medium infestation (1–3 rooms, basement) | $1,500 – $6,000 | Includes removal of moldy drywall, insulation, and carpet. |
| Large infestation (multiple rooms, attic + HVAC) | $6,000 – $15,000 | Deep cleaning, air duct sanitization, and post-remediation testing. |
| Whole-house mold removal (post-flood) | $10,000 – $30,000+ | Includes structural repairs, dehumidifiers, and air quality testing. |
Homeowners typically pay between $10–$25 per square foot for remediation. Factors like local labor rates, accessibility, and moisture source repairs can influence total costs. Coastal and humid regions such as Florida, Louisiana, and Texas generally see higher prices.
