"The inspector contacted me prior to my appointment to get some preliminary information in preparation for our meeting. He arrived on time. We spent some time discussing my concerns about possible settling of my home's foundation and then walked through the basement and exterior. He performed a detailed inspection of the home externally and internally, taking numerous measurements. He showed me the measurements and explained his findings. It turned out, there was no serious settling or shifting of the foundation. Ultimately, his recommendation was to take no action. I appreciate his thoroughness and honesty."

"They are overpriced, did not take proper precautions to protect our carpet, promised us professional carpet cleaning, then sent out two of their guys with rags and a shop vac to “clean” the carpets. Then we were told it’s not policy to send out carpet cleaners, and that we’re on our own. We were promised 4 different things involving quality of the project, none were done. This place is a total scam, and has SERIOUS communication and misinformation issues internally. Would never use them again. All they did was open up walls, spray some stuff, made a mess, and left us to handle any problems stemming from their lack of attention to detail, and crappy policies."

"Hired FSRG to install a sump pump in basement and a driveway trench drain in front of garage door. They installed the trench drain directly underneath the garage door and we had to insist that it be relocated. After the next heavy rain the sump pump vapor locked and water overflowed from sump well into the basement. FSRG would not address the vapor lock issue stating that they install these pumps all the time and they work fine. My biggest complaint is not that the job was plagued with problems but that I was made to feel like a problem customer when I informed FSRG of the issues with their installation."
