Get matched with top radon gas testers in Lake Harmony, PA

"Excellent, very satisfactory. Radon Brothers' rep came, saw the problem, and replaced the leaking radon exhaust PVC pipe in my basement floor. All in record time. Am very satisfied and will continue using Angi contractors."

"Incredibly well! The people from Anvil were kind, courtesy, and professional from the moment I called until they left my home. Highly recommend using them if you are having any concerns at all around Radon. Tom was especially helpful and knowledgeable."

"The whole process was easy. ETR were quickly responsive to questions. Professionally discussed in related terms test results over the phone. Highly recommend!"

"The home we are purchasing is in another state, we were not able to be there for the inspection. Our inspector was Vincent, we were sent a VERY detailed report with pictures the next day. The inspection included Radon testing and wood destroying insect inspection since we'll be moving to PA. We are very pleased on the timeliness and the recommendations given in the report. We would definitely recommend this company!!!!"

"I can't say enough about how professional they are.  I met the regional manager at the property and he explained what we were looking for and how he would test for radon. He also explained how their system worked and how it might be implemented if there was a problem. The test results are evaluated by a 3rd party testing company so I knew the results would be accurate and wouldn't be influenced by SWAT Environmental.. <br /> The tests came back positive with fairly high levels of radon (over 80 PiC/L).  James came out a second time and explained how they would install the system and retest, guaranteeing that they would get the radon down below 4 PiC/L  They scheduled the installation within a week.  The installation technician, Sean, was unbelievable.  He was neat, courteous and did a fantastic job with the installation. All holes were clean and neat, the exterior work was excellent and they even took the pipe up through the overhang to the roof - minimizing the visual impact of the system on the home.  The pipe and fan system were painted to match the gutters and really fit in with the rest of the house. <br /> The system brought radon levels down to 30 PiC/L but not enough to resolve the issue.  The house is unusual construction - it's on a two level slab and the floors and ceilings are beam and plank construction - no joist cavities.  The house was originally built and owned by an architect so the construction is unique and unlike any other house we've seen. I'm not surprised we had problems getting the radon levels down on the first try.  The amazing thing is they came back and installed a second system AT NO ADDITIONAL COST.  Their guarantee is more than just giving your money back - they continued to work on the two systems until radon level met EPA standards.  <br /> That's how amazing this company is.  There was never a suggestion of them pulling out or making excuses.  I can't say enough about how professional this company is.  I work in the construction industry and never have I run into a company that is as committed to resolving problems and great customer service as this one. If I could hire these guys to do my construction work my life would be so much easier and I'd hire them tomorrow if Sean or James wanted to jump ship. <br />"

"Overall it went well, however, he missed testing the smoke alarms otherwise I would have given an <br /> A rating. Seemed to be a little in a rush but was prompt for the appointment, courteous and professional. Report was available the next day (with pictures). Would have liked to have had the report on site. <br />"

"We were given the contract and he explained to us the treatment methods and the removal of debris. We hired them because of their price and they were less invasive to the structure of the house. It was clean and we didn't have to cut any of the drywall. The only thing I am not happy about is that they lost the contract, they did not have the signed contract. The guy that came in and did the inspection and gave us the estimate lost the contract. Then when the guys came in to do the work they claimed that the removal of debris was extra, about $900 and that's a lot of money. I specifically called him to make sure that the debris was going to be removed by them and that was included in the price. They came in and did the job. The pricing was good but you have to be very clear about every item on there, and we were but when they lose the contract, that was a major setback. They didn't do any post treatment testing. He said that the testing was expensive and they already knew that we had mold so they just did the treatment."

"Did an excellent job. He was punctual and efficient in his job compared to other contractors either came and never gave me an estimate or never came at all. Will be using him again to put in 2nd vent for other bathroom which is going to be more complicated."
