"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

Dehumidifiers do not directly remove mold or spores from the air. However, by lowering the room’s humidity, spores are less likely to flourish when landing on surfaces.

Mold on window sills is common, especially in damp or poorly ventilated areas. Windows are prone to condensation, which creates the moisture mold needs to grow. Dust, dirt, and other debris on the sills can further feed mold spores. While it’s not unusual, it should be addressed quickly to prevent further growth and potential health risks.

The duration of mildew smell in carpets depends on several factors, including the extent of moisture, cleanliness, and ventilation. If promptly addressed, the smell can diminish within a few days to a couple of weeks after thoroughly drying and cleaning the carpet. However, in severe cases or if not properly treated, the smell might persist. Persistent odors could indicate deeper mildew growth, requiring professional cleaning or, in extreme cases, carpet replacement to completely eliminate the smell.

Painting over mold is not an effective solution and can actually make the problem worse. Instead, it traps moisture, which allows mold to grow and spread beneath the surface. Mold must be completely removed before painting to ensure the problem doesn’t recur. If mold is painted over, it may eventually seep through the new layer of paint, causing discoloration and peeling.

Yes, you can use bleach to remove mold from your aluminum siding, but it’s a powerful cleaning agent, so make sure it’s diluted with water first. A solution of one part bleach and four or five parts water works well. But it’s still a good idea to start by cleaning a small, inconspicuous area of the siding to make sure that the solution doesn’t cause damage or discoloration.
