What We Do Best:

Our radon services cover every step, from identifying elevated levels to installing systems that reduce radon long term.

Radon Mitigation

Design and installation of radon mitigation systems tailored to slab, crawl space, and basement foundations.

Radon Testing

Short-term and long-term radon testing using calibrated devices with clear, defensible reporting.

Radon Consulting

We provide expert radon consulting services to help homeowners, real estate professionals, and contractors understand and address radon concerns with confidence.

Proven Work. Measurable Reduction.

Every radon project follows a clear process. We begin with certified testing, review the results with you, and explain your options. If mitigation is needed, we design a system specific to the structure and install it to meet current EPA and ANSI/AARST guidance. Post-mitigation testing verifies performance, and all results are documented for your records, real estate needs, or permitting.

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.

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.
