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.
Questions to Ask Before You Hire
- Where do you think the moisture is coming from, and who fixes it?
- Will you set up containment and negative air, and how will you protect the rest of the home?
- Who does the clearance testing after the work, and is that person independent from you?
- What exactly will you remove, and what will you clean and keep?
- Is your company licensed for mold work where this job is?
