Dover Radon Inspectors from people just like you.

installed a radon mitigation system that started in an unfinished room in the basement, went through a false" wall into another unfinished room in the basement, up through a wall into the garage, up the wall and into the crawl space above in order to place the fan and vent the PVC out the roof of the garage. They ran into 2 unexpected structural issues but resolved them easily. They were prompt and courteous. Radon test run after installation showed 1.6 pCi/L, a great result. after an earlier reading higher than US EPA action level of 4.0 pCI/L. I would highly recommend Cavalier!

-Donna S.

"The installation went well, both installers arrived within the provided time frame and finished the job within a few hours as expected. They installed the system" where I had desired it to go (
as much as possible) in the utility room in the corner and they routed the piping/ductwork outside by the chimney stack to further conceal the looks of the system. My reading while low at 5.1 was still higher than the recommended 4.0 level so I wanted a system in place for peace of mind. After I sent them back the retest kit they left I received my results back within 3 days or so and my reading was down to a 0.4 well below the recommended level. Both installers were friendly and did answer my questions and concerns and explained to me the process of the system. Overall I would recommend
again for anyone who needs a Radon System installed.

Radon is a colorless, odorless gas that occurs as a decay byproduct of uranium and thorium. Radon forms naturally in the environment, and low levels can be detected in soil, rock and ground water. Homeowners that inhale radon are at risk of lung cancer and even death.

Radon Testing reviews in Dover


They arrived on time and explained everything they were going to do. They worked quickly and installed a pvc pipe from the basement up through the garage and out the roof. They had the job done within an hour and a half. Would highly recommend!
- Kate E.

They arrived a day early and completed the bulk of the work in less than a day, ready for the inspector the next morning. While they struggled a bit to find the street end of the pipe due to poor city maps and multiple

on the

, once found the work went very quickly and efficiently. We were out of service for about 2 hours. They were able to slide the new pipe in place without bursting the old and managed very little damage to complex landscaping. They did a thorough job of cleaning up after themselves. A very solid job and pleasant experience on time and on budget. I would certainly recommend them to anyone needed a sewer line replacement.

was very knowledgeable, friendly, and professional, and thoroughly answered all of my questions when he came out to quote the repair. He was also available very quickly and provided a detailed quote, which were critical since we were in the inspection period for purchasing a house. The sellers chose to go with another company for the repair based on price.

did a great job - he reduced the average level of Radon in the house from 6.6 pCi/l to 0.4 pCi/l. He was also very polite and responsive. He was happy to answer all of my questions and was a pleasure to work with.

Vent. They thought they had sealed
everything, but I had to get them back to seal a sump pit cover. Had
a second leak, which they came out and fixed. But they acted like
they were doing me a favor.
Two subsequent leaks
I just fixed myself, as calling them was a hassle. They only would
come by if one of their techs was in the neighborhood.
About a year after
installation, the fan failed. They came back (again, when they were
in the neighborhood), and replaced the fan. But they charged a $90

I selected
Dover Radon Inspectors Provider Name Locked
mostly because of the good reviews on Angies list and also because I had the option to pay in advance through Angies list. JP contacted me on the Monday immediately following the Saturday I had paid for it, and we agreed on an install date.
JP showed up at the right time and we quickly zeroed in on the most appropriate place to install the system. I went along with all of his recommendations which were well thought out.
Two and a half hours later the job was done. That includes drilling 3 inch holes through the slab and the wall, installing the fan and a vent pipe going up 3 floors, wiring in the fan to the electrical, caulking, and sealing with hydraulic cement. I was pretty impressed that all of that got done in just over two hours.
As of this moment I haven't sent the test kit in yet - you have to wait 48 hours before taking the sample. JP gave me a written guarantee that the system will keep levels below 2pC and I can see the thing pulling air from below the slab, so I'm pretty confident.
Overall experience for me was great - I have no complaints at all and I would recommend them to anyone looking for a radon system.
- June B.

Making an appointment was quick and easy.
Dover Radon Inspectors Provider Name Locked
showed up to the house even before I got there and was already long at work. He involved me in the inspection process and provided his insight and recommendations on many areas that I would have missed myself. He was very professional and personable as well. He checked everything, even things that I would not have even thought were worth looking at, but truly were. He did a very thorough and complete inspection. Also, the inspection report was e-mailed to me within 24 hours of the inspection! Very quick! He uses separate people that specialize in termite and radon inspection, which showed up at the same time as the home inspection. This was particularly nice as I had no additional phone calls to make to setup appointments, and they provided discounts for their services off their regular price as I had gone through

Great experience from start to finish. I set up an appointment in early September to get an estimate,
Dover Radon Inspectors Provider Name Locked
showed up at the scheduled time and explained clearly the most likely issue causing high radon levels and what they would do to fix it. We set up another appointment for them to come back for the repairs. The employee showed up as scheduled and got right to work. He cut out a section of the mitigation pipe, dug out the blockage that was between the pipe and the water proofing trench, and replaced the pipe. He then sealed the sump pit cover as well as several feet of wall where the water proofing system was not correctly finished. Our radon level prior to repair was 5.9pCi/L. The EPA guideline is for the level to be no more than 4.0pCi/L. After repairs, our level was 0.8pCi/L, well below the EPA guideline. We are extremely pleased with the service
