See Service Area →Is it a job for a pro?
The EPA says you can usually clean up a small area of mold yourself, roughly under 10 square feet, about a 3 ft by 3 ft patch. Call a professional when:
- The mold covers more than about 10 square feet
- It came from sewage, a flood or a long-running leak
- Water soaked drywall, carpet or flooring and hasn’t dried within a day or two
- It’s inside walls, under floors or in the HVAC system
- It keeps coming back after you clean it
- Someone in the home has asthma, allergies or a weakened immune system
Why water damage turns into mold in San Pedro
Homes near the harbor and the Point Fermin bluffs sit in marine air most of the year. Morning fog and the May and June marine layer keep humidity up, so wet materials dry slowly here, and older homes from the early 1900s often have little insulation or ventilation. Bathrooms, closets on outside walls and the space under raised floors are where it usually starts.
What to ask before you hire
- Are you licensed with the California Contractors State License Board? (Check the number at cslb.ca.gov.)
- Have you handled this kind of job before, and can I talk to a past customer?
- How will you find and fix the moisture source, not just the damage?
- How will you keep spores and dust out of the rest of the house during the work?
- What does the estimate include, in writing?
- Will the work follow the IICRC standards: S500 for water damage, S520 for mold?
- Do your technicians hold IICRC certifications such as WRT (water damage) or AMRT (mold)?
Licenses and standards in California
California doesn’t issue a separate state license just for mold work, but since 2025 any job of $1,000 or more in labor and materials needs a contractor licensed by the CSLB. You can look up any license number in a minute.
Many restoration companies follow the IICRC standards (S500 for water damage, S520 for mold) and train their crews in IICRC courses such as WRT, AMRT and MRS. These are voluntary, so ask which ones a company uses.
Common questions
Is this service free?
Yes. The call costs you nothing. The company you talk to pays for the referral.
Are you a restoration or mold company?
No. We connect San Pedro homeowners and renters with independent local professionals. Here’s how it works.
What should I do right after a leak?
Stop the water if it’s safe, stay clear of anything electrical, and start drying. See the first-hour checklist.
Do I need mold testing?
Often not. The EPA says that when you can see mold growing, testing usually isn’t needed. Testing can help when you smell mold but can’t find it. More on testing.
I rent. Who pays?
Tell your landlord or property manager in writing first. In California, landlords are generally responsible for fixing the water problems that cause mold.
