We used Keystone Mitigation to clean up after an unfortunate roof leak in our bedroom. We were referred to them by our roofer, and we're so glad he recommended them! They came by to assess the space on a Tuesday, and were back on Thursday to cut out the damage and dry out the room. It was more involved than we thought, and included our ceiling, wall, and part of our wood floor. We had to wait a bit to get moving on the fix due to insurance, but as soon as we got the insurance go-ahead they jumped right back in to start the work. We unfortunately had a high deductable, but Keystone worked with us to stay within our remaining budget. The wood floor was patched, and we were concerned about how it would look, but it ended up looking incredible! If you didn't know it was patched, I don't think you'd even notice. Over the course of a couple of days, they sent people out to do drywall, build an inset shelf which was an "extra" that we wanted just to make the room a bit nicer, and spackle and paint. I couldn't believe how quickly they responded and everything came together. They're incredibly communicative, I never felt like I didn't know what next steps were or when they would happen, and they were really responsive to questions. I sincerely hope we don't need remediation again, but if we do I will absolutely be reaching out to Keystone Mitigation!

Got air quality test prior to mold quote and got around 13k in both attic and basement
Super friendly and responsive guys. Worked around my busy schedule. At end of process they did an air quality check (has to be requested). It drastically decreased the count (around 1.4k in basement and less than 200 in attic). Since the count was slightly high in basement, they came in again to do another round and redid the duct cleaning for free. Did another quality test afterwards. Got less than 500 in basement.
If you need to go through insurance (I did not), they have done it before, so they know the process.

Keystone Mitigation Services went above and beyond for our family during one of the most difficult and overwhelming times of our lives.
My mother passed away in her home, which triggered a massive insurance event that required the entire house to be cleaned out and mitigated. The situation was emotional, complex, and something we had never navigated before. From the very beginning, Bobby communicated clearly, consistently, and with compassion. He sent detailed videos, explained each step, and wasn’t afraid to ask the hard but necessary questions — which gave us confidence that nothing was being overlooked.
What truly set Keystone apart was the human aspect. This wasn’t treated like “just another job.” Bobby and the team genuinely understood what our family was going through. We live out of state, yet they handled the entire situation seamlessly, professionally, and with care — which lifted an enormous weight off our shoulders during a time when we were already emotionally exhausted.
In moments like these, trust matters more than anything, and Keystone earned ours completely. Their integrity, transparency, responsiveness, and compassion are unmatched. I cannot recommend them highly enough. If you are dealing with a loss, an insurance claim, or a situation that feels overwhelming, this is the team you want in your corner.
They are truly the best.

Keystone Mitigation Services did an outstanding job supporting a large scale pharmacy move. The level of organization, efficiency, and care their team provided was exceptional. Bobby and Jamie are hands on owners who clearly prioritize quality, communication and customer satisfaction.
The crew was punctual, professional and handled sensitive pharmacy equipment and materials with precision and respect. Everything was executed smoothly, safely, and on schedule- no small feat for a move of this size.
If you are looking for a reliable company capable of managing complex, large volume moves, Keystone Mitigation Services is absolutely the right choice. Highly recommended!
