"We were very pleased with the services that our mold remediator, Greg, provided. When mold was found in the ceiling of the closet where our sump pump was located. Greg blocked off the area and professionally completed the work. Upon inspection of his work, the mold was completely gone. Our ceiling where the mold was previously located was clean, fresh smelling and in perfect repair. We strongly recommend Greg!"

"SEECC did VOC testing, mold and bacteria testing in my apartment. They did remediation to resolve the issues. The owner David was very knowledgeable and professional .He came out before my scheduled appointment to do the testing. The remediation was done immediately after the test results. He and his son went above and beyond my expectations. I would highly recommend this company. Linda S"

"I have a beautiful cedar pavilion that was being overcome with mold. Five other companies came out and gave empty promises and never followed through. Brandon from Buckeye showed up, said we can do this. Within a day a quote was emailed and five days later my pavilion looked like the day it was built. This was a great experience. I highly recommend them!"

Mold Testing and Remediation FAQs, answered by experts

Beyond looking for visible signs of mold in a home, you can tell if your house has mold by undertaking testing. You can hire a local mold testing company to run the test for you, giving you a sure answer. Professional testing is often the best way to determine whether you have mold, as some types of mold may grow in places where you can’t easily see them, such as behind walls.

Nearly all homes have at least some airborne mold spores. If you want to determine the concentration of spores in the air, you have a few options. The most effective option is to hire a professional tester who can take air samples of the home. The tester would send the samples to a laboratory to determine the concentration of mold spores. 

You can do a basic home water test, but we recommend having a pro conduct a more in-depth test. This method is accurate, and you’ll have a pro who knows your house helping you determine a plan of attack for anything out of the ordinary.

Seeing black dots around the air vents is alarming, but don’t worry. It’s probably just a build-up of soot and darkened dust. Soot is just a byproduct of burning organic materials, so it tends to form in the winter months.

Mold can grow on garage ceiling insulation, which is why it’s important to install a vapor barrier behind the insulation and keep the space cooled and heated as you would your living area. Doing so will more or less eliminate the risk of mold growing on your garage ceiling insulation. You can also install a self-draining dehumidifier to help remove moisture, or opt for a foam board insulation or spray foam insulation that won’t harbor moisture and mold.
