"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"

Mold Testing and Remediation FAQs, answered by experts

Turn off the water main immediately. Hire a professional plumber to check on your pipes and make any replacements so you avoid water damage. You don’t want to take any risks with flooding, so it’s best to consult a professional plumber as quickly as possible.

Many peel-and-stick wallpapers aren’t moisture-resistant, so if you install them in high-humidity rooms, mold can grow behind the wallpaper. It’s best to reserve peel-and-stick wallpaper for bedrooms, living rooms, and other rooms with lower humidity levels. Not only does this minimize the risk of mold growth, but it also keeps the wallpaper from bubbling or peeling.

No—there are key things that help you determine if it’s mold versus mildew. Mildew is a specific type of mold. Both can trigger allergies, asthma, and respiratory symptoms, though mold is typically more severe than mildew.

If a professional mold inspector finds mold in your home, they’ll conduct mold testing to determine the type of mold species and the number of spores in your home. This plan will help develop a remediation plan, where a mold remediation specialist will remove the spores from your home. Since mold remediation costs the average homeowner $2,225, it’s best to treat mold at the first sign rather than waiting.

Sewer gas in any location can cause eye and respiratory irritation if you’re exposed at low levels, or more severe symptoms if you’re exposed at high levels—but fortunately, the fresh air outside means it’s less likely to affect your physical health. However, sewer smells outside can still indicate significant plumbing problems that will need to be dealt with, such as a potentially damaged sewer line or roof vent pipe.
