1. Ask Where the Water Is Coming From

Mold needs moisture. The patch is only the part you can see. If the water problem stays, the mold can come back.1

A clear answer names the source. It also says who will fix it.

Visible mold on a bedroom wall in a maintained home.

2. Ask About Jobs Like Yours

Ask how often they handle work like yours. Then ask for references. The EPA recommends a contractor with mold cleanup experience.2

Relevant proof beats a broad sales claim.

Start With Question 1

Enter your ZIP to request a call from a local mold removal pro. Then ask where the water is coming from.

Ask these on the call

  1. Where is the moisture coming from, and who fixes it?
  2. What is in the written scope, and what is not?
  3. Who approves extra work before it starts?
A plain work scope with room photos and a mold stained drywall sample.

3. Get the Scope in Writing

Rooms. Materials. Removal, cleaning, disposal, drying and repair. Get each one on paper.

Then ask what is not included. That one line can stop a small gap from becoming a large bill.

A clean tile beside mold affected ceiling tile and carpet.

4. Ask What Stays and What Goes

Some porous materials can be hard to clean. Ceiling tiles and carpet are common examples. They may need removal.2

Ask how that choice is made before work starts. Then nothing comes as a surprise.

Furniture moved away from a wall with visible mold.

5. Ask How Your Home Is Protected

Ask how they control dust and debris. Ask what you need to move.

A clear answer helps you prepare. It also shows how carefully they plan.

A homeowner checks a credential beside a mold stained drywall sample.

6. Check Every Credential Yourself

Ask who issued it. Ask if it is current. Ask how you can check it.

A badge on a website is a starting point. The check takes two minutes and it is yours to make.
