"Guy and his team at Affordable Mold have simply been amazing to work with, very professional, responded right away, great pricing and trusted them in our home. We moved into a new home and after few weeks we discovered water damage and mold in 4 rooms after some heavy rainfall. Our Insurance company sent out a restoration crew that were not very responsive so I called Guy at Affordable Mold to take a second look. He came out the same day I called and took over the job for us. His crew showed up the next morning and took care of the affected areas. They handled everything from demo, clean up and the rebuild of the rooms. Their rebuild work was exceptional and very quick. They spread plastic on the floors, covered vents and cleaned up after their work every day. We had our rooms back in full use in no time. I highly recommend their services and definitely will use them again in the future if needed, not just for mold removal. His team of guys can do it all! Thank you Guy!"

"My technician Tanner was extremely knowledgeable and friendly. After looking at my home and surveying for mold, I decided to have the air tested which he did right then and there. I am still waiting for the results but it was nice to know we had no mold issues."

"For those of you looking for an honest, kind, caring person in the world of “hazardous vapors” look no further than this company. Kevin at All Clean Environmental Services took my panicked call on a Saturday and listened in detail about health concerns regarding “moth ball odors” in my family’s rental property. With that he volunteered to come and “check out” the offensive odors. Kevin was very discreet as well as thorough in his handling of visit to “our” home. Having never dealt with this problem he was quickly in contact with his suppliers of treatment options."

Mold Testing and Remediation FAQs, answered by experts

If you own a stereo microscope, you should be able to see the fibers. The stereo microscope often can perform magnification up to 50x. But unless you have experience viewing asbestos fibers, you may not know exactly what you are seeing. Some fibers are curly, while others are long and straight. Blue, brown, white, and gray colored fibers are all possible.

Yes, brown spots on a ceiling are usually caused by water leaks and can lead to mold growth, especially if you don’t correct the underlying problem. Ongoing water leaks and moisture issues will almost always result in mold growth, especially if you live in a warm climate. Mold is a health hazard, so get the root problem fixed quickly, clean it, and encapsulate the area to avoid mold formation.

Drywall can be toxic to the environment and to humans in some cases. As drywall breaks down in a landfill and comes in contact with other organic chemicals, it can create hydrogen sulfide gas or leach into the groundwater. Additionally, the CDC recommends methods for controlling the inhalation of drywall dust when handled. While the common ingredients of drywall—gypsum, silica, and mica—are naturally occurring, they can cause irritation in some humans.

A mold inspection costs an average of $660, with a typical range between $300 and $1,025. However, costs can be as low as $150 or as high as $2,800 depending on several factors. These include the size of your home, the type of mold, the extent and accessibility of the affected area, your location, and the number and type of samples required. Hard-to-reach areas like air ducts, crawl spaces, and wall cavities can increase the cost. Specific tests have different prices; for example, swab testing typically costs $200 to $300 per area, while more extensive air testing can range from $250 to $700. A thorough inspection is crucial for determining the scope of the problem and identifying the best remediation method.

Mold doesn’t take long to form, especially in dark, isolated areas like under the floorboards, where you’re less likely to know it’s wet in the first place. Mold can take root and proliferate in just 24 to 48 hours, but it can be up to a week before you start to notice funky smells.
