Mold inspection: a guide for pros
What customers ask, how to win the job, and what to put on your profile.
Offering mold inspection
You inspect homes for visible mold and moisture sources, and take samples when the findings call for them. Clients rely on you for a clear, documented report that separates the moisture problem from the growth and explains what the lab results show.
What customers ask
- Where is the moisture coming from, and is it still active?
- Do you take samples, and what will the lab test for?
- What do the results mean, and what do they not show?
- Will you tell me what needs cleaning and what needs a moisture repair?
- Are you licensed or certified for this work?
- Can you test again after the repair?
How to win the job
- On the first call, ask for the history of leaks or floods, the locations of the odor or growth, and any health concerns the client wants addressed, then say what you will test
- Take moisture readings in the walls, floors and ceilings before you open anything, and record the readings by room
- Explain why each sample is taken and where it is taken, so the client sees the reasoning behind the cost
- Put the moisture sources in the report first, with the photos, since fixing the source comes before any cleaning
- Write what the lab results do and do not show, so the client does not read them as a full clearance
- Offer a post-repair test with the same method, so the client can compare the readings
What to put on your profile
- Post photos of moisture findings with the readings labeled, with client details removed
- List the moisture meters and the sampling methods you use
- Show a sample report with the lab results and the moisture source list
- State your license, certification and the states where you work
Follow-up that helps the customer
- Offer a post-repair re-test to confirm the moisture has dropped to the level the report expected
- Suggest a yearly check of the bath exhaust, the crawl space vapor barrier and the gutters, since these are common moisture sources
- Offer to keep the sample results and moisture readings on file for the client's records
Licenses and permits
Mold inspectors are often required to hold a state license or certification, and the rules differ by state. Check with your state licensing agency for your credential, the continuing education rules and any rules about separating inspection from remediation work.
Questions
What do I do if a client wants a clearance letter after the cleaning?
Explain what a clearance covers, based on the samples and the readings taken. Do not issue a clearance for areas you did not test, and put the limits in writing.
How do I report a moisture source I cannot access?
State in the report what was not accessible and why, and recommend that the area be opened and checked by a licensed contractor. Do not state a cause you have not confirmed.
