If the contamination is under 10 square feet, the mold remediation can take as little as one day. If over 10 square feet, we use the following guidelines:
- Preparation (which includes containment) and installation of engineering controls can start immediately.
- Demolition and sanitizing can be completed in one to two days in many cases.
- After remediation work is completed, the air scrubber must run 24 to 48 hours.
So, in all, 1-2 days if the mold is under 10 square feet; 3-7 days if the mold is over 10 square feet.
