Testimonials

Customers, Realtors, Builders.

A contractor advised that they were not able to put in a window bar countertop in my kitchen without an architect and drawings. I knew that was not the case. Quin company came in and in a few short weeks, Ralph made my vision come to life with limited direction and under budget. Highly recommend for any home improvement. Honesty & Integrity still alive in the Upstate!

The home inspection of my future home revealed a high level of radon present. I contacted Ralph Quin, a certified mitigation contractor who had performed the same service for my neighbors. Mr. Quin provided a free estimate of the work, performed the work without delay and will be following up with yearly testing. My realtor was so impressed with his service and work that she will be referring her future clients to him.

Mary Beth S.

My realtor recommended Ralph Quin after I bought my house and found out that the radon mitigation the previous owner had installed wasn't actually doing the job. Ralph quickly identified the real source of the problem — something the original installer had missed entirely — and designed a custom solution that properly addressed it.
He was incredibly knowledgeable, patient in explaining exactly what he was doing and why, and a genuine pleasure to work with. As a bonus, the basement looks noticeably better than it did before. I'd recommend the Quin Company without hesitation to anyone dealing with a radon issue.
