"Once contacted, Gregory Paxson provided timely and very professional mold and remediation services. Besides finding mold in several areas of the home, he also discovered the cause of the mold. All of the damaged materials were removed which allowed the plumbers to repair the water leaks that were causing the mold. Mr Paxson then was able to remove and replace the damaged insulation in the crawl space. During that work, he also discovered an additional structural problem that had to be addressed. In summary, Mr Paxson successfully completed removing the mold, conducting microbial remediation steps, replacing the damaged insulation, and installing a new crawl space vapor barrier ."

"I can't say enough about Joe and Frank. They know their business. The mold problem was remediated quickly and efficiently at a reasonable cost. I highly recommend Failsafe, they were neat, clean, and safe. The containment area was impressive with negative air pressure maintained to avoid spreading spores. This is a big job, with multiple aspects to repair the crack in the outside wall to prevent further issues. Failsafe accomplished its portion flawlessly. The mold and musty smell is gone."

"Since this work is technical and specialized, I cannot judge work quality and value for money, but the overall experience was very positive. They came on time, were pleasant and efficient, and inspired confidence in their ability to do a proper job. They were totally professional. They called to give me the results as soon as they were available, with an emailed written report a few days later. I chose this firm to test for asbestos in a ceiling because they do only testing, not the remediation work should the result be positive."

"CSI was flexible and was able to schedule a home inspector the day after I got a bid accepted on a house. The inspector, Patrick, showed up on time and the inspection took about 4 hours. Patrick was responsive to any questions I had by email or live during the inspection. My one recommendation is that I requested a pest, mold, radon, and home inspection. It would be a better heads up if they explained that they sometimes outsource the radon inspection depending on availability of radon inspectors. Also, they can explain a bit more for new home buyers what is involved with a mold inspection. Patrick ended up just eyeing whether he spotted any mold. Because he did not see any mold, we did not have to pay extra for mold samples."

"Remedia-Pro arrived on time as scheduled, talked with me about what I wanted them to do, and gave me a price upfront. They did a fabulous job--our 8-year-old, pet-stained berber and plush carpets looked like new when they were done. They also offered tips on how to treat stains immediately to keep them from setting in. Great experience, will hire them again!"

Mold Testing and Remediation FAQs, answered by experts

Fiber cement siding is resistant to mold and mildew, so it won’t be as affected by these problems as something like wood siding. However, damage to your siding or improper installation can still lead to water getting behind your siding, in which case, mold can grow behind it and damage other building materials. Contact a siding repair professional if you suspect you have a leak.

Eliminating mold from wood permanently poses a challenge as the mold spores have the ability to deeply penetrate the porous wood surface. While surface mold can be effectively eradicated with proper cleaning and preventative measures, it's difficult to guarantee its non-recurrence under favorable conditions. To prevent mold from reappearing, it is important to identify and resolve the root cause of the moisture that triggered mold growth initially.

Ensuring appropriate ventilation and a dry environment, or consider applying protective finishes such as sealant, varnish, or paint to prevent future moisture penetration and mold growth. Consistently inspect and maintain the area to keep the wood free from mold in the long term.

Mold can begin growing in as little as one to two days after your ceiling has been exposed to water. Mold grows and spreads quickly and can cause serious health problems. Always ensure areas with leaks are fully dried out, and any damaged material is replaced to discourage mold growth.

You normally won’t see any dust or mold actively floating out of your vent, but you might notice your vent looks dirty. Mold will cling to the sides and collect almost like black soot. Dust will look, well, dusty, but there will usually be a heavy buildup so expect thick gray layers on the bottom and sometimes the sides of the vent. If you suspect you have mold in your vents, call a professional immediately.

Unfortunately, mold can grow pretty much anywhere, on any kind of surface. However, you’re most likely to see it in damp areas like basements or bathrooms, as well as anywhere there has been a water leak. Consult a local mold specialist to determine if certain areas of your home are prone to mold based on climate and other factors.
