"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!"

"We attended a dinner to be introduced to the products of Quality Eco Technology (QET) last week. The lively and dynamic presenter (Dale Wood) provided us with impressive information about household problems and solutions. We agreed to invite QET's regional representative (Jason Gamse) to inspect and evaluate any problems in our home. With clarity, experience, and effectiveness, he explained all the necessary steps and costs to us. The inspection revealed some problems, like mold, lack of insulation, and unwanted chemicals in the water. Jason took pictures of all problem sites. We agreed to a very decent discount. The next day, the friendly and efficient crew, Darrick and Travis, arrived on time, and began the jobs promptly. In the attic we had some multi-layer insulation added to some trouble spots, mold treatment, and a solar fan installed. A mold block was put in the crawl space. We also had a whole house water filtration system and the pro-biotic system installed. Each installation was clearly explained as to purpose, warranty, and maintenance requirements. Upon completion, each area was removed of debris and cleaned. All in all, the experience from dinner to inspection and recommendations to the final installations was a pleasurable experience and made our home (and us) more healthy. Five stars!"

Mold Testing and Remediation FAQs, answered by experts

Yes, drywall mud can get moldy—though the presence of moisture is required for this to happen. That’s why the best way to keep your powdered drywall mud fresh for as long as possible is to keep it in dry storage conditions. If you live in a humid area, it might not make sense to stockpile a lot of powdered drywall mud before you’re ready to use it. As for premixed drywall mud, avoid opening the container until you’re ready to use it—and don’t expect it to last longer than six months.

The high humidity of steam showers creates the ideal environment for mold growth, so it’s important to stay proactive against it. Along with regular cleaning, run your bathroom fan during and after your steam shower. Keep your shower door open and any doors and windows in the bathroom to allow the space to air out properly. If you come across ugly mold spores, spray them with undiluted vinegar, let it sit for at least an hour, and then scrub away the mold.

Yes, a one-time water leak can cause mold. Depending on the conditions, mold can begin to grow within 12 to 48 hours. The risk increases with the severity of the leak, high humidity, and when water soaks into absorbent materials like drywall. To prevent mold growth, stop the leak immediately and ensure the area is dried completely; running a blower fan for 24 hours is recommended. If you do notice mold, it's best to call a mold removal specialist to address the situation.

Yes, if there is mold in your drywall mud and you then use it to build walls in your house—or if mold develops in your set drywall, like it can in hot and humid areas—it can lead to illness. Mold in your drywall (or other parts of your home) can make existing respiratory conditions or allergies worse, and the effect can be more intense for those who have existing health issues or compromised immune systems.

You might be wondering, “Is laminate flooring toxic?” The product does contain formaldehyde, which is found in the resins used to bind the wood fibers together. But the chance of overexposure and adverse reactions, such as allergy- or asthma-like symptoms, is low unless you are exposed to formaldehyde in other places, i.e., if you work with formaldehyde regularly outside the home. Keep in mind, too, that many household products have the potential to pose a health hazard, such as cleaning products.
