"I highly recommend Apex Radon Solutions. From getting the estimate to getting the work done, everything was just outstanding. Marco and his crew of 3 men showed up early and were all knowledgeable and extremely skilled. I had to install a radon fan and put in piping and electrical. They measured the piping with care and accuracy and did an excellent job with the installation. Iâ m truly impressed with the professionalism and quality of the work. They were also very reasonable with their prices. Thank you Apex for such great work."

"This review is from a seller where an inspection was performed. The heat was not shut off after the inspection and my family and I walked into 90 degree temperatures because the heat was never turned off when the inspection was complete and it was on for 7 hours until we got home. In addition the mud room has a thermostat and electric heater and that was also left on high which we did not realize until the next day. In addition, to prove a point to a potential buyer he forced a hole through the wood in our detached garage reporting that there are signs of water damage. The garage is from 1930, there has been water in the garage especially when we had the hurricane last year but they could have just written that in the report not damage our property to prove a point. Coincidentally, the same inspector came back with another interested buyer and yet another piece of wood was pulled off from the garage. If that is not bad enough, the same inspector gave confidential information from a previous inspection to a new potential buyer which led to another buyer terminating the deal. I know this as our lawyer communicated with the potential buyers attorney and said that the inspector passed on information about a previous inspection he did at our house a week earlier.. in addition, our neighbor and friends were outside during the outside portion of the inspection and they heard the inspector give the potential buyers and their real estate broker information about the last inspection and what the other potential buyers said. So much for confidentiality."

"Do NOT hire Fernando of Northeast Mitigation System to do any work for you. He installed a radon mitigation system at our house a year ago and it took him three attempts to get it under the recommended 4.0 pCi/L. He kept making excuses about why he couldn't get it right, including saying we needed a sump pump. Now, a year later our levels are extremely high again (11.0!) and he is refusing to honor his warranty on the system. We did end up installing a sump pump within that year to avoid flooding issues and he now says that having a sump pump could be causing problems for his system and conveniently doesn't remember telling us that we should get one installed. He is extremely unprofessional and has been nothing but a headache to deal with. I've never had a more frustrating experience with a "professional". Save yourself the trouble and hire CT Basement Systems instead."
