"I can’t say enough good things about Procyon. When a sudden flood in my basement occurred, their team responded with urgency and professionalism, arriving promptly and fully prepared. They quickly assessed the situation and got to work immediately. They ensured that every bit of moisture was taken care of, preventing any future mold or structural issues. I was especially impressed by their attention to detail. They didn’t just focus on removing the water, they also followed through with thorough drying, disinfecting, and post-remediation inspections to ensure my basement was safe and sound. They communicated with me every step of the way, which gave me peace of mind throughout the entire process. Thanks to their efforts, what could have been a disaster turned into a manageable situation. I highly recommend Procyon for anyone in need of reliable and effective remediation services. Their dedication, expertise, and customer care were second to none."

"As a realtor, I found Rich from Expedient Environmental Solutions while searching for a client who needed mold remediation. He and his crew did an excellent job at a fair price. They finished on time and left the home clean. So, when I was looking personally to have basement waterproofing (interior french drains and sump pump) along with radon mitigation, I received 3 quotes, of which theirs was the most comprehensive plan, and again not the highest quote overall. They finished the work ahead of schedule by bringing four workers the second day, were respectful throughout and left the area reasonably clean. I'm confident that my days (and nights!) with the shopvac and flooded basement are finally over, and grateful they stand behind their work for a full year. Good contractors are hard to find. Glad I found them. Thanks and I highly recommend!"

Biohazard Remediation FAQs, answered by experts

Mold remediation costs between $1,200 and $3,750 in most cases, but the exact price will depend on the extent of the mold issue and how accessible your attic space is. Keep in mind that this price range only includes the removal of damaged materials. Your total might be significantly higher if you need professionals to provide build-back services, too, like replacing damaged insulation or roof decking.

While you can attempt to remove mold from ductwork using a mixture of water, baking soda, and laundry detergent, flexible ducts are fragile and may tear when you scrub at the mold to remove it. If you suspect mold is growing in your flexible ductwork, it’s best to contact a professional for help.

In some cases, yes, it’s safe to spray hydrogen peroxide on your mattress, but the solution can damage memory foam mattresses, so you should only use it on non-memory foam mattresses. If you have a standard spring mattress, you can mix hydrogen peroxide with cold water in a 1:1 ratio and spray that on your urine-soaked mattress. If you’re cleaning pee out of a memory foam mattress, swap out the hydrogen peroxide for white distilled vinegar, or call in a professional mattress cleaner to avoid doing damage to your mattress.

Yes, mold can grow under your shower tiles if they aren’t thoroughly waterproofed. Even if you have a durable, non-porous tile material, water can make its way through grout or gaps around the edges of the shower. This will slowly erode the grout, which can cause tiles to come loose. It can also trap moisture behind tiles, and within a day or two, mold and mildew can rapidly grow.

No, if you have paper towels or rags that are soaked in mineral spirits, you can’t throw them out like you normally would with household trash. When contaminated in this way, such objects are deemed hazardous waste and can only legally be disposed of with a hazardous waste collection program.
