"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

When used in the correct quantity and with the right procedures, boric acid will produce fumes with limited to no toxicity. You’re more likely to experience adverse side effects from boric acid toxicity by accidentally ingesting it or touching it with bare skin. All the same, wearing an air-filtering mask is a good way to keep even minorly toxic fumes out of your system. Don’t forget gloves, too!

Iron sediments from rusty pipes are not likely to cause health problems. While a glass of yellow-hued water is off-putting, it is generally safe to drink yellow water in the short term. But you certainly want to address this problem. In the meantime, switching to bottled water until the yellow water issue is resolved is a good idea. 

You probably have mold on your shower curtains because mold and mildew thrive and spread in warm, dark, wet, and unventilated spaces. Your shower is the perfect environment, especially the shower curtains, because they trap water in the folds and creases, plus they’re exposed to the most water spray. The best way to ensure mold stays off your shower curtains is to keep it dry so it doesn’t have a place to grow. Doing this can also help keep mold off your bathroom ceiling.

Humidity, moisture, and a lack of ventilation can all cause mold to grow on surfaces in and around your home.

Homes should be checked for mold annually, especially if you live in an area with high humidity or frequent rainfall. Inspections are crucial following flooding, roof leaks, or plumbing issues. More frequent checks are necessary if your home has a history of mold problems or water damage. Regular inspections help detect mold early, preventing costly remediation and minimizing health risks, especially in moisture-prone areas such as basements and bathrooms.
