Featured companies are clients of the marketing agency that runs Healthy Home Directories. Featured placement is not for sale. How featuring works
We start with every water damage and mold business on public business records in California.
We keep companies that are open and have at least one customer review, and merge duplicates.
We read each company's own website and record which mold services it says it offers.
Companies whose websites show they do not do mold work are left out. Confirmed mold remediators are listed first.
Owners can claim a listing to correct details or add photos. A person checks every claim. Published by Healthy Home Directories.
Start with the license question. California has no state mold license, so no license search will show who does mold work. Rebuilding is different: if the job means replacing walls, floors or framing, the company doing that part may need a contractor license from the Contractors State License Board, and the questions at the end of this page explain when.
Mold grows where water stays. The EPA puts it simply: "The key to mold control is moisture control." Before you compare treatments, find out where the water came from. A roof leak, a wet crawl space, a plumbing drip, sprinkler spray against a wall or flood water each need a different fix, and a company that treats the mold without dealing with the moisture leaves you with the same problem. The EPA also advises drying water-damaged areas within 24 to 48 hours to prevent mold growth.
Use the services grid on each listing to narrow the field. It shows what each company offers: mold remediation, mold inspection or testing, testing again after the work, crawl space and attic work, HVAC and ductwork, emergency service around the clock, help with insurance claims and free estimates. A check means the company offers it. "Not enough info" means we could not tell either way, so ask.
Testing is a fair question to raise. The California Department of Public Health does not recommend testing to find the type or amount of mold, because those results say little about health risk, and the EPA says no federal limits have been set for mold or mold spores. Testing after the work is different: it checks the result of the job you paid for. Some companies test before and after the work, and some send samples to an outside lab. Ask which they do and who reads the results.
Get the answers in writing before work starts, and talk to at least two companies.
We start from public business records for California and keep companies that are open and have customer reviews. Then we read each company's own website to see which services it offers. Companies whose websites show they do not do mold work are left out, and companies that confirm mold remediation are listed ahead of those that offer related work, such as water damage restoration.
No. The California Department of Public Health says there is no legal requirement in California for training, licensing or certification of mold assessors or mold remediators. A contractor license is a separate matter: the Contractors State License Board requires one for construction work of $1,000 or more, and for smaller jobs that need a building permit or use hired workers. You can look up any contractor on the board's Check a License page. Certifications such as IICRC or NORMI are private, not state licenses.
No. Every listing is free. Featured listings sit at the top of a city page and are labeled Featured wherever they appear.
It means the company's own website says it does mold remediation. Listings without that mark offer related work, such as water damage restoration, and may also handle mold; call and ask.
Use the contact page. A person checks every request, and the directory is rebuilt with the change.
