"The team from Stay Dry was very professional. They were informative and transparent when describing what the work would entail and sent me pictures and updates throughout the day. They went out of their way to provide a thorough service. It is hard to know who to trust when having mold remediated because the levels of training and expertise are very different across companies. They are skilled and they care about the quality of their work and customer service. I will hire them again for the next project."

"We had a leak in our camper that left us with a tremendous amount of water in the ceiling and slide. Patriot was incredibly helpful by providing multiple fans and a dehumidifier to remove the water, coming to our site for a follow up, and testing moisture levels to ensure the camper had been dried out completely. They ensured we took the proper steps to avoid having any mold issues and allowed us to get the camper back in working condition ASAP. I would highly recommend Patriot Restoration to anyone that need this service in their homes!"
PHG was able to shut off the water source, removed damaged ceiling, walls, and cabinets; and begin the cleaning, disinfection, and drying process quickly.
Water had penetrated the drywall and saturated the insulation. Mold had started growing on the surface and behind the drywall.

Mold Testing and Remediation 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.
