Best experience with any contractor, ever! Ric is prompt, professional, polite, and really knows what he's doing. His prices also are outstanding.

Ricardo Rodriguez of Radon Installation Contractors LLC did a great job with the mitigation at our house, and I highly recommend him. Were I to have it to do over again, I would definitely call him first and last if he was available to help us with a radon issue.    He answered the phone call for my initial inquiry during what I retrospectively figured out must have been a family gathering for Memorial Day, he patiently answered my questions about his services and pricing, and asked pertinent questions about my home’s structure and radon history, etc. The next day, he followed up with some email info, as he had said he would. We soon came to an agreement over the phone, and I was lucky enough to reserve an appointment for early the next week.    He showed up slightly early, inspected the relevant areas, and we discussed and confirmed the planned installation configuration. He got to work right away, was very careful about choosing an effective and safe place to drill the side of my house for the exhaust, and began installation of the PVC piping and electrical components. He drilled the intake hole through the concrete basement slab, leaving literally no dust emissions in the area. He installed the interior and the exterior PVC as unobtrusively as one might reasonably hope, and showed me how to take it down and re-install it should we need access to the adjacent chimney for masonry work, etc. He completed the installation of the mitigation system components, and familiarized me with the meaning and use of the vacuum pressure sensing device which was reading a healthy .65” Water Column.    That pressure measurement was quite reassuring, because in the course of drilling the basement slab intake hole, Ricardo had penetrated into the vicinity of the plastic drain tile pipe which, in our house, had been installed inside of the foundation perimeter. I had forgotten all about this and the fact that the drain for the stairwell we installed several years back flows into that drain tile. Were we just sucking air from the stairwell drain, or was there a meaningful negative pressure under the foundation that would expel radon gas out the pipe over our roofline? Read on.    Ricardo also quite thoughtfully ascertained the low likelihood of a proper re-sealing of our basement slab after installation of plumbing work there during a remodel a few years ago. We breached the drywall in the affected area, and I was so grateful he thought of this: the floor slab was still open at the tub. He re-sealed it for me to get a good, tight negative pressure under our slab (except for the stairwell drain which wasn’t practical to try to correct at this point).    As Ricardo was preparing the final documentation for concluding our business, he charged me about 15 bucks more than I thought this was going to cost. That’s obviously not a lot of money, but it annoyed me a bit, until I considered the extra work he had put in for which he had not explicitly contracted. Besides, I figured if we needed more work in the event that the radon measurement results didn’t come in under the EPA Action Level, it would all come out in the wash.    Our Fairfax, VA area house was built in the 70’s. The EPA Action Level for radon in homes is 4 pCi/L (picocuries per liter) of air. When we bought the house in 1990, the charcoal canister radon measurement was 6.5 pCi/L, so we weren’t all that worried about it. However, when we retested in 2006, the charcoal canister results measured, on average, 12.3 pCi/L in the basement. Now, after Ricardo’s mitigation system installation, our Liquid Scintillation radon measurement was .4 pCi/L and .5 pCi/L, so our radon levels are now about 1/10 of the EPA action level! This was a much better result than I thought we had reason to hope for. We’ll test again periodically, but now we can confidently make full use of the recreational and office space available in our basement. Thanks Ricardo!
