We can offer Mold Testing and Remediation. Water Damage. Smoke Damage. Fire Damage. Our owner is on site for all jobs! Call today we work flawlessly with your insurance company.

"I had a poor experience. I hired this company to do a mold assessment in my apartment. I dealt with the owner. First, he requested cash or check payment only. He made an appointment and did not show up or contact me. I had to call him. In one of the rooms, the pipes above and whatever else the cause of the leak was, had been leaking repeatedly for 40 years, and the plaster constantly replaced. I was worried about mold ABOVE the ceiling on the beams and studs and not just the visible mold on the ceiling plaster and I worried it could be black mold. He did not seem to listen to what I told him and he did not use a water meter to check for saturation or a borescope or any other tools except taking a surface sample and air sample (the borescope and water meter I did not know about until after I had paid him for this inadequate job). He did not mention anything I said in the report. He was also rude and unkind and never provided me with a receipt."

"I paid this company $600 to test the air in my detached garage. The results showed Cladosporium, which many professionals told me is extremely common. What happened next was one of the most uncomfortable experiences I’ve ever had with a home-service company. They sent me a remediation proposal for over $45,000, and in my personal opinion the scope, tone, and sheer intensity of the warnings felt completely disproportionate to the situation. The estimate was filled with pages of dramatic health claims that, to me, came across as fear tactics rather than professional guidance. When I asked questions, the owner was extremely rude and dismissive on the phone. The whole thing felt pushy and uncomfortable. After leaving an honest review, things escalated in a way that shocked me. The owner contacted me and offered a refund only if I signed a notarized disclaimer that he drafted. I personally found that very unusual, and I chose not to sign anything. What concerned me even more was what happened next: after I declined to sign the document, a negative review suddenly appeared online about my wife’s business — at our home address — claiming she had done work for him and stolen $600 from him. In my experience, this was completely untrue. My wife has never worked for him in any capacity. In my personal opinion, it felt retaliatory and deeply unprofessional. I ended up getting several second opinions from other mold professionals, all of whom felt the quote I received was excessive for what was found. Based on my experience with the customer service, the tone of the estimate, and the way things unfolded afterward, I would strongly recommend that other homeowners get multiple quotes before agreeing to anything. In my personal view, the way this situation was handled was alarming, unprofessional, and not in the best interest of the customer."

FAQs for toxicity and mold removal projects in Katonah, NY

Remediation should keep mold from returning as long as the moisture source is eliminated. Fix leaks, control humidity, and replace water-damaged materials, then schedule periodic inspections to stay ahead of new growth. With those safeguards, your home can stay mold-free for the long haul while protecting both health and property value.

Most pros recommend leaving the home while they work on mold remediation. Removing mold stirs up airborne spores that can aggravate respiratory issues, and contractors can work more efficiently in an empty space. A short, temporary relocation keeps everyone in your family safe and lets the crew finish the job without interruption.

Mold shouldn’t return once the moisture problem is fixed. Stay vigilant: repair leaks right away, keep humidity below 50 percent with a dehumidifier placed in damp areas, and improve ventilation where needed. Routine checks for leaks and mold and quick repairs go a long way toward keeping your home mold-free.

Mold spores can trigger nasal congestion, throat irritation, coughing, wheezing, eye irritation, or skin rashes. People with asthma, allergies, or weakened immune systems often feel the effects sooner and more intensely. Some molds also release mycotoxins linked to serious respiratory or neurological issues. Swift remediation and better ventilation are the best defenses.
