"Did mold remediation in 2020 before house was purchased. Mold found in attic. Resolved it with a 4 year warranty expiring 3-23-24. In January 2024, found mold in same spot. They inspected and sent an estimate to remove. Asked about the warranty still in place. Never responded. Did a good job of remediation work. Doesn’t support their warranty."

"Jon came by for a consult to look at some ugly looking black staining that was growing in my basement. He was very professional and punctual and thoroughly explained why it was not mold, but harmless mildew and how to rectify it. I was so appreciative for his integrity and honesty and I will absolutely use Indoor Environmental if I ever do get mold in my house."

"I had a positive experience with Rey and Giovanni at My Pure Environmental. Both were responsive and professional throughout, and they scheduled and performed the mold remediation on my house quickly and on a schedule. Rey was easy to work with in terms of scheduling, and Giovanni was nice and professional in person and kept me updated."

"We hired Green Home Solutions for mold remediation. We quoted another vendor and Green Homes price was fair so we selected them.

"I am very happy that I had All Clean Environmental Services to fulfill my project. They are extremely reliable in all aspects, price is reasonable. The terrific asbestos removal job was done, my place is left been very clean. The most important for me was a direct and clear communication with Kevin from the first phone conversation, during the project and after it was finished. He is a very knowledgeable specialist and the nicest person. Kevin went above and beyond making me been comfortable and absolutely worry free. Would like also mention that I appreciate how detailed were Kevin and Sorany with all documentation I was getting from them via emails. Thank you so much, Kevin and Sorany! Highly reccommend this company!"

Mold Testing and Remediation FAQs, answered by experts

Many caulk alternatives are safe for use in kitchens and food preparation areas, provided you apply them correctly and let them cure for the right amount of time. If you’re unsure about this step, call in a pro to do it for you. Silicone putty and caulk strips are often used around sinks and countertops due to their waterproof and flexible nature. Always choose products labeled as safe for kitchen use and follow the manufacturer's instructions for proper application and curing.

It is generally not safe to live in a house with smoke damage, as even minor damage can pose long-term health hazards and structural risks. While it might seem safe temporarily depending on the severity, you should relocate if there is major damage or visible soot. Smoke smells and residue contain dangerous particulates and chemical compounds, including carcinogens, that are hazardous to breathe and can cause respiratory issues. These signs of damage are not always visible but can have dangerous short-term and long-term effects on your health, belongings, and your home's structural materials. You should not stay in the house until a trained professional from a smoke remediation or restoration company has assessed the damage and determined it is safe to return. Your insurance company may cover the cost of alternative housing while the professional work is completed.

No, not all black mold is toxic. Although people often refer to stachybotrys chartarum as toxic black mold, there is little evidence that any one type of black mold has more toxicity than another. People who have an allergy to black mold would be more likely to have a dangerous reaction after inhaling it. Long-term exposure to black mold spores can lead to severe infection and disease. Some people only have minor health problems after black mold exposure. Ultimately, toxicity is rare with any kind of mold, but it is possible, so always take the appropriate precautions.

A stain from a water leak will usually be brown and concentrated in a single area where the water is originating from. You may find it under a damaged section of roof, under an upstairs bathroom, or beneath your HVAC system. Stains from condensation are more likely to be widespread since they don’t come from a single point of water intrusion. Condensation stains also look blotchy and may smell musty, and they won’t be concentrated in a single area on your ceiling.

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.
