"Did mold remediation in 2020 before house was purchased. Mold found in attic. Resolved it with a 4 year warranty expiring 3-23-24. In January 2024, found mold in same spot. They inspected and sent an estimate to remove. Asked about the warranty still in place. Never responded. Did a good job of remediation work. Doesn’t support their warranty."

Lead paint can be found in almost 75% of all housing built before 1978 and a dangerous mold infestation could exist in any home no matter how old the home is. A professional inspection from ASAP Environmental is the best way to protect yourself before you buy.

"We had a pipe break in our kitchen ceiling and an issue with condo owners that felt “the mold was everywhere”. Christopher was amazingly knowledgeable and explained all of the issues without being an alarmist putting us all at ease and did a thorough inspection. As an architect for 40 years he was the best mold expert that I have met and would highly recommend them."

"Matt did an excellent job. He came to my house, assessed the basement, offered to arrange for a dumpster, and removed the damaged items left by the previous occupants. He provided two quotes, one including the dumpster fee and one without. A week later, he returned and worked quickly and efficiently. He was polite, professional, and hardworking throughout the process. Thanks to his efforts, my basement no longer has a moldy smell, and there’s no sign of mold, which was our biggest concern with winter approaching. I highly recommend his services."

Mold testing and remediation services FAQs

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.
