Our fan went bad after 3 years. We had Certified Radon (original installers) come out to replace our fan. Something was not properly sealed and moisture trips the circuit. Now that fan trips the circuit breaker, my sump pump is on the same circuit. They will not come and fix their install problem for over a month. The only advice was to TURN OFF MY FAN for the 5 week wait, so that my sump pump will work. Disappointed.

Tech came out on time, explained what he would do and then answered questions I had. Estimated two hours to complete the job and he was exactly right. Installation was perfect. Follow up three days later and tech arrived a few minutes early. Radon level now at 0.8. Overall excellent service and would highly recommend this company.

Other than a couple of rescheduling of appointments, one due to the tech having the flu, everything was completed in a professional and timely manner. The price paid was the price quoted. The rescheduling of appointments was done in advance and was not a problem for me. The work completed was neat and professional and the tech ensured a clean area before he left. Note that the price reflects a $100.00 discount.

Very unprofessional. Instead of showing up during the approved appt time to set up the radon test, they used the IBOX set up by my realtor to enter my house about an hour earlier. I was in the shower (yikes) and walked out in a towel while the technician was in the house (double yikes), and my young daughter (who was home at the time) was totally freaked out that a stranger was in the house. When I called them to complain, they said the technician had randomly moved up the appt time without telling anyone at the central office or confirming with my realtor that this was OK. I called them to explain how the IBOX is not a free-for-all to enter people's houses whenever they would like. They didn't really take responsibility, instead it was, "I'm sorry you're upset," kind of thing. Overall, they seem like they have good reviews, so maybe this was a one-off incident.
Description of Work: They were hired by realtors to do a radon inspection in advance of selling my house.

Went great. Both the estimator and installer tried to come up with a solution that would work as an interior option for our house, which unfortunately didn't work due to the layout of it. I was really surprised the installer tried finding an exterior option since at the point where he came out we had already agreed on the interior option. He could've just done the agreed upon job and called it a day, so I really appreciated him taking the extra time to look everything over once again. I would hope this wasn't just his way of doing things and that the company trains all their people in good customer service like this.

The tech had a tough time finding a good location to put the pipe in so the person who had come out for the estimate and the tech weren't on the same page. The tech was able to get it handled though, and his work was good. I was not pleased so much with the guy who came out to pick up the tests. My house had a security system, and I was not told of the time of his arrival. I asked him how he was getting into the house, was an agent meeting him, etc. because I wasn't notified. He proceeded to read my alarm instructions and code out loud in my driveway. That was probably the worst part of my experience. The rest of the disorganization was probably normal. I changed my alarm code after that because I had already experienced one theft since the for sale sign was put in my yard. My central air unit had been stolen, and I wasn't taking any chances since the alarm code had been announced.
Description of Work: I needed a kit installed to lower the radon in my home. It was not a high level, close to borderline, so I didn't need an extensive system. The price and workmanship were fine for the most part.

The woman I spoke with at Certified Radon answered all of my questions and scheduled my appointment with ease. They arrived on time and picked up the test equipment on time. I received the radon gas results the same day! The whole process was quick and easy. The staff and technician were professional and courteous. If I decide to test radon in my home again in a couple of years, I am calling them back. I would definitely recommend Certified Radon!

My experience with Certfied Radon couldn't have been better. When I first called, they were able to pull up pictures of our house and we discussed the layout of the basement. They confirmed that they could locate the fan and vent pipe in the back corner of our house where we wanted it and gave me a firm quote at that time. The technician arrived right on time and was very professional. The installation took around three hours and the quality of work was outstanding. In talking with the technician it was obvious how much pride he took in his work. He left a radon monitor which was picked up a few days later. Our radon level was reduced from 5.6 to 1.2.

Excellent from initial contact through completion of installation. I liked that they did not recommend using sump hole and explained why. They also cared more about external cosmetics than ease of installation. Would highly recommend to others.

Very professional radon service provider. Great communication (phone calls and emails) from start to finish. Technicians were courteous and arrived timely to complete work. The technicians discussed the work that was to performed at my home then reviewed the work with me when they completed the job. Provided a cost guarantee when initial quote was provided. Extremely pleased with their service.

Came out to give me an estimate. He was very honest and said that it would not be professional of them to do the work until I took care of the water problem in the crawl space first. After all of the rain we've received this summer, I've come to the conclusion I need to install a sump pump. We visited for awhile as he listened to my concerns and he gave me a reference to call. I was grateful for his honesty and insight. He estimated cost as a minimum of $2,000, it's a rather large crawl space covering the entire foundation. Please note, it wasn't cost as the reason work was not done, I need to take care of other issues first.

This was a $50 big deal purchase and it was fine; that was some time ago. They did what they said they were going to do, I have no way of judging if they did it average or exceptional. I spent a few hundred dollars more than the price of the deal for the system. I was in a crisis selling my house and I had to get it done.

Travis, Madison, and everyone I have encountered with Certified Radon has been extremely professional. This company has grown quickly in the time I've worked with them but have always been able to keep up with the growth and demands. They have always been pleasant, courteous and punctual. Having radon mitigated from your house isn't exactly glamorous, but I've never had a complaint from a client about their service or product. I highly recommend Certified Radon!

They did an awesome job from the start to the finish. The initial radon test showed a radon level of 5.5. Note - the builder installed a passive system when the house was built two years ago and had the vent pipe sitting on top the footing. So nothing was venting out. So Certified Radon drilled a new hole, patched the old hole, added new piping and added the vacuum pump to activate the system. After activating the system, the radon level dropped to 3.5. At no additional charge, they came back out and vented the garage (large three car attached garage) to the active system. After the garage was connected, the radon level drop to 0.6. All of the interactions with the company (from the office people, to the field people, and to the installers) was outstanding. They are good people!
