"Dave was extremely helpful in giving grounded, low cost solutions for my ongoing mold issue. Proving sound and reliable advice in a sea of so much overwhelming information was invaluable. He took the time to look over a previous report that provided misguided information and recommendations and took the time to walk me through the correct steps saving me so much time and headache. Thank you so so much. I highly recommend this company for their mold services and consult."

"This was not the first time using an Air Quality inspection company. They were help full, accessible, timely, accurate, and provided an analysis report that included a representative to review and answer questions. They also provided a referral to a remediation company that approached the issue in an efficient and cost effective manner."

"For anyone looking for a reliable and honest company- I highly recommend Pacific Pure Maintenance. After having exposure to TOXIC mold in my home, I had Pacific Pure Maintenance quote the project for mold remediation. My insurance company however, had me go with another company that cut and removed the mold without doing any kind of treating to the air. Months later I was still ill and contacted Pacific Pure Maintenance and they were very knowledgeable and helpful. They removed the toxins /air spores that were continuing to make me sick. (Something that other companies did not do NOR recommend). At the time, I knew NOTHING about mold exposure and I was looking to the experts for advise and none of the other mold removal companies were as helpful as Pacific Pure Maintenance. I am forever grateful to this company for doing what other companies didnt and going above and beyond."

"We hired California Healthy Home Inspections during the middle of a mold remediation job. We suspected we were getting the run around, so we hired them to do mold sampling/testing and help clarify and understand our situation. California Healthy Home Inspections helped save us over $3000 dollars that a shady contractor was attempting to charge, and educated us to handle the remainder of our job. I would definitely recommend California Healthy Home Inspections."

FAQs for mold testing and remediation projects in Berkeley, CA

Some states require mold removal specialists to be licensed, while others require licensed mold testing companies to create remediation protocols that any contractor can carry out. You can use our state licensing tool to find requirements in your area. In either case, it’s imperative that you hire an experienced professional for mold removal to ensure the safety of your home and your family.

It’s possible to scrub mold off of visible surfaces yourself, but it’s not usually a good idea. Mold is not only a potential health risk, but it’s also difficult to treat in its entirety, especially because it can grow behind walls and in other hidden areas a DIYer might miss. Since mold is a serious and often pervasive issue, you should hire a professional that will remove all of the mold—including any that might be hidden—run industrial air scrubbers to remove airborne particles, and complete mold testing to ensure the underlying problem is solved.

The most effective way to remove mold includes testing affected surfaces and the air for spores, creating a protocol for removal, carrying out the steps within the protocol, running air scrubbers for the recommended amount of time, and then completing a post-remediation round of testing to confirm the issue is solved. Since this work is very involved and there are health risks if done incorrectly, you should always hire an experienced professional to handle mold removal.

The average cost for mold remediation is around $2,200, and most projects fall somewhere between $1,100 and $3,300. Your total will depend on many factors, including the surface area that is affected by mold, the extent of the issue, how much building material your professional needs to replace, whether or not testing is necessary for safety reasons, and existing indoor air quality.

Mold removal will take between one and five days in most cases, but severe mold issues can take several weeks to correct. Your timeline will depend on how much mold there is in your home, where the mold is located, and how much testing and aftercare is required. If you have mold behind your walls or you have an excessive amount of mold that requires removal and running air scrubbers for several days, you could be looking at over a week for the process to be completed.
