Customers say: True professional

"I am so grateful to Johnnie and Chris from Mid Hudson Home Restoration! My husband and I hired them on two separate occasions. First hire - there was water damage in the basement and possible mold. I consulted with Johnnie over the phone and he quickly arranged for a visit. He quoted us that the work will be done in 3-5 days. Johnnie and Chris carefully took apart the dry wall, remediated the mold, and sealed everything up again in the timeframe they promised. They also repainted our entire basement and did a great phenomenal job. Second hire - we had a ceiling leak from an unknown source. Johnnie cleared his schedule for us and came immediately once he saw the video we sent. He found the source of the leak within minutes and over the next couple days, replacing the ceiling and sealed everything up. Johnnie and Chris are detail oriented and thorough with their work. Above all, they are warm, honest people who truly care and take pride in what they do."

"Thomas Candella did a great job identifying the source of the mold issue, managing and remediating the mold - this was my first experience with mold and Tom was very patient with all my questions. He was professional at all times - from the first call to Robert Kye, the owner to the last visit, putting up the drywall, painting and providing pictures for submission to the insurance - I highly recommend Certified Mold Removal, Inc for all your mold issues. Mold in the home is not healthy."

"Project: Remove damaged kitchen cabinets and sheet rock caused by water damage. They came in with a crew of workers and removed the cabinets and drywall and insulation. Performed Mold Remediation where needed. Set up blowers to dry everything out. Very professional and reliable. They cleaned every thing up and left the area spotless. Would highly recommend."

"When I initially discovered I might have had asbestos in my cracked flooring, I was very anxious and scared. I got connected with Christian the same night the discovery happened. He answered a lot of my panicked questions with calm and patience. As frantic as I was he was very understanding and helpful. My experience with Christian was great and I definitely would recommend him. I contacted another asbestos tester before reaching Christian, and they treated me with disrespect and could not care less. If you want someone who is understanding and attentive to your situation, dont look anywhere else! Thanks again Christian!"

"I just got done speaking to Spencer on the phone who was very generous with his time running through all the potential contaminant issues, breakdown of Oasis services, and was very candid on whether i should even proceed with any testing. If i do proceed I will certainly pick this company."

"Extremely professional operation. These are the best people to use to diagnose any indoor air quality or mold, radon, etc. To me, it’s important to separate the person evaluating the condition from a company that also happens to offer remediation services. That’s my personal opinion and not any type of blanket statement. They were readily available, the Lead Contact was a. man named Mark Stern, who is a total Environmental professional. Fortunately, we had no issues, but wanted peace of mind, which we got in a very detailed Inspection and Report within a day or so. Happy to recommend them to Inspect, Test and Report on possible Indoor air safety issues."

Mold Testing and Remediation FAQs, answered by experts

Excessive humidity in a room often manifests through visible signs like condensation on windows or walls, a musty or damp odor lingering in the air, peeling wallpaper or paint, and the presence of mold or mildew. Experiencing discomfort due to a consistently clammy or sticky feeling can also indicate high humidity levels.

Turn off the water main immediately. Hire a professional plumber to check on your pipes and make any replacements so you avoid water damage. You don’t want to take any risks with flooding, so it’s best to consult a professional plumber as quickly as possible.

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.

Mushrooms do not harm your yard. In fact, they can actually help improve your lawn health by decomposing woody organic matter in your soil, and breaking it down into nutrients that feed your grass and plants.

Mold grows in areas with humidity levels above 60%, but ideal conditions for mold growth occur when humidity is between 70% and 90%, especially in poorly ventilated areas. To prevent mold growth, aim to maintain indoor humidity levels between 30% and 50% using dehumidifiers, proper ventilation, and temperature control. Regularly check your home's humidity with a hygrometer to help you monitor and avoid conditions conducive to mold.
