"Radon Systems LLC did a great job. I had a radon level of around 6.5 in my basement for years, and finally decided I needed to address it. After receiving 3 quotes, I had Dave from Radon Systems come over to do the job. I initially was resigned to having the PVC pipe go up the side of my house, but Dave found a way to run the piping inside the basement and go thru the garage, with only 18" of PVC sticking up past the garage roof. Excellent! And now my radon level is around 1.0 to 1.5 all the time. The entire job took half a day, and Dave was clean, respectful and easy to work with. I absolutely recommend them."

"He was on time, arrived at 9am as quoted and began to install the system. The system required two suction points and a sump pit cover. The sump pit originally had a pedestal pump in place and none of the other radon companies would change the pedestal pump to a submersible pump as required for the mitigation system to function properly. Rhino Radon not only changed the pump but installed a back flow check valve to ensure proper functioning of the system. All of the other companies said we would have to employ a plumber or a handy man to get this done. Had we gone that route the closing would not have happened. Rhino Radon gladly did all the work required and didn't even break for lunch!!! He was more concerned with getting us out of the vacant house seeing we are already down the cape. The system that involved a crawl space and being vented through the garage roof was completed immaculately and the test results came back at 0.5 pCil/L. This pleased the lender and buyer and exceeded our expectations. We highly recommend Rhino Radon Services.

"They arrived on time on 3/29 and explained exactly what was going to happen and proceeded to get set up. They worked all day and when ready to leave cleaned up & advised what would be done on day 2. Everything went as expected on day 2. They were courteous and professional and I would definitely call them again.

"What a surprisingly wonderful experience we had with BioClean. I was able to schedule a same day appointment, and Brian and Dennis showed up exactly on time. Both men are absolute professionals, and are extremely honest! Within minutes of entering the home, they measured the air for particulates, and said that it wasn't a high reading at all. They proceeded to test around our home, and also up in the attic where the air handler is. The thought to look in places we never would have thought to look, but they said everything was actually in good condition. We did figure out that there is moisture in the basement coming from what may be a leaky toilet on the main floor - which we never would have known. The took their time, were very thorough, and made no money from us (with the free estimate coupon they posted here on Angie's List). They could have told us anything, and we would have believed it (and probably paid through the nose). But - these guys truly are wonderful, honest, and professional. If we have more work to do after the plumber comes to fix the leak, we will DEFINITELY call them to do the work. On a scale of 1 to 10, they are a 43."

"Roland was professional and timely. He came to repair a garage door that lacked a counterbalance and a fence that needed new hinges. I was told he was going to be a few weeks on an estimate due to demand and he came when we agreed he would and managed to get me on the schedule sooner than anticipated. The repairs took about 5 hours, 1 more than he anticipated, but he stuck to the quote he gave me and remained professional and courteous throughout all our interactions. I would definitely recommend him, and certainly plan to call him for future projects."

Radon Detection and Reduction questions, answered by experts

Keeping radon from getting into your home is much better than having to get rid of it once it's already indoors. While there may not be a way to fully prevent radon from getting into your home, there are things you can do to reduce the gas's ability to enter. 

Sealing foundation cracks and openings can help keep the gas from seeping inside. Improving air flow, such as by opening windows, can also be helpful. If you're building your home from scratch, talk to your contractor about using radon-resistant construction to keep the gas out.

The cost for a radon mitigation system typically ranges from $800 to $1,500, with an average around $1,000. The final price depends on several factors, including the size of your home, the severity of the radon issue, and the type of system required. Your home's foundation type also significantly impacts the cost. For example, sealing and ventilating an unfinished basement might cost around $4,600, while encapsulating a crawl space without a foundation slab can range from $1,500 to $15,000.

Use a radon test kit or hire professionals to conduct a detailed assessment of radon levels in your home.

Mitigation can take several days depending on home setup, equipment accessibility, and achieving effective diffusion system sealed efficiency.

You can vent radon out of your house sometimes by simply opening a window, but it won’t remove the source, and will likely rise above recommended levels quickly. A professional will be needed to assess your home, and determine the best strategy for radon removal. Active radon sump pumps and soil depressurization systems are often used to forcefully vent the radon from your home.
