Can You Handle It Yourself
DIY with care
Federal guidance treats about 10 square feet, roughly a 3 by 3 foot patch, as the line for a careful homeowner with gloves, goggles and an N95. Past that, or when mold is inside walls, in the HVAC system, or someone in the home has asthma or a weak immune system, hire a specialist.
