  We woke up to a wet, partially collapsed hallway ceiling on July 3. We made two calls--one to the AC company to assess our attic AC unit, and one to Keystone Mitigation. The kind receptionist assured me that we had called the correct company and that Bob would be out before the day's end, despite the holiday weekend. Four hours later, he was up in our sweltering attic, found the problem, did a temporary repair. He assured me the insulation would dry quickly, so no need to worry about mold, and that I should be able to find a contractor to repair the drywall and repaint at a reasonable cost, otherwise his company could handle it. He provided a video of the issue, ran into the AC technician as he was leaving, and briefed him on the problem. Bob even texted me several hours later to be sure the AC had been fixed and was working in the 100 degree heat. All this, and he didn't charge me for the visit. I hope not to have this problem again, but I wouldn't hesitate to call this company if I do.

  Vanessa I can not be more appreciative of the whole crew that I have interacted with throughout a major fail in my building management dealing with an hvac pipe breaking which led to a major pool of water under it caused black, green and white mold to grow everywhere near it. My building finally addressed it, told me i should just move as a solution. They never communicated with me after Bobby came right away, to assess. Days later, as my 19 year old cat and I were staying at my family's house for an entire week, Bobby was and still is, the only one communicating with me about the project. Im assuming the building chose to have an hvac company take the hvac out, with zero training or any care about the air vents having mold. Or did they even mention it. They spent 4 hours in my apt in which time they decided to use compressed air in the system without any acknowledgement of the mold issue or containment in any way which spewed w massive amount of brown thick toxic residue, spores, dirt, and who knows, filling the air in my apt. My mouth was numb from breathing whatever they caused, visibly, to fill my entire apt. My cat was puking for 24 hrs. They left for an hour and told me it was not a big deal BUT apologized for it as they left. They clearly made the spread of the mold worse than it could ever have been. Keystone however, showed up with the proper and pretty cool containment procedures, left my apartment cleaner than it was when they got there and did the work with zero AC in a heat wave, in a plastic bubble oven for hours. My apt looks like a Dexter kill room for now with zippered plastic from floor to ceiling but it shows exactly the serious level of this kind of situation and I can not even believe how insane the random guys hired a few days earlier who obviously have no idea how much more toxic they made my home or care. These guys took it seriously, looked out for each other on the job and super professional but easy to talk to while setting up an outbreak containment area and working in it with a great attitude in 100 degrees..i can't be more impressed and grateful. 7/1/2026

  My house flooded causing water and mold damage. Bob and Jamie were beyond amazing! Bob came out a few hours after I called, adding me at the end of his work day. He was in constant contact throughout the entire process. Jamie brought his crew a few days later to do the job. Jamie dotted every I and crossed every t. He definitely knows what he’s doing:.They did an awesome job and left no stone unturned. They have also been VERY helpful in my dealings with my insurance. They truly take care of you like you are their own family. I am so glad I found them!

  We thought we had a problem. My wife called Bobby and he came out and looked through every area of our house. He really listened to our concerns and investigated. Attic, basement and everywhere in between. Checked our HVAC air filter, checked our sump, looked outside, so much more. Really put in time. When he finally came back and told us his recommendation was a service he doesn't even provide (HVAC clean/sanitization) i was surprised. To spend his time and put in that much effort and not even try to sell us a single thing... that's a rare level of honesty. Would definitely use him again, no questions.

  I highly recommend Keystone to anyone who has experienced water damage. Their expertise, professionalism, and customer service exceeded my expectations. We had a great experience with Keystone while dealing with water damage from leaky pipes in my home. From the initial assessment their team was professional, knowledgeable, and responsive. They took the time to explain each step, answered all of my questions, and made a stressful situation much easier to manage. The crew arrived on time, worked efficiently, and treated my home with care and respect. They covered the floors, all furniture and doorways so dust from their work didn't spread throughout the house. There was a decent number of boxes in the basement with water damage, they moved everything with care so they could complete the entire job properly. This was above and beyond service that was greatly appreciated. The communication throughout the project was excellent, and they kept me informed every step of the way. Their attention to detail and commitment to doing the job right gave me confidence that the mold issue was properly addressed.
