"SWAT did a great job installing the radon mitigation system in my house. They were very responsive, coming out quickly to provide a quote and offered a discount if the neighbors in the connecting townhouse would sign on as well. Installation was quick and the system was installed with no problem whatsoever. The radon levels in my house dropped from a reading of 12 to “undetectable” in just a couple of weeks."

"Did a great job wit the inspection and I feel a lot more confident about the move. The only downside was he showed up a half hour late. I'm sure it happens from time to time, but it is something to be noted if you are in a time crunch."

"I bought my home over six years ago, and James did my home inspection. I have never had such a through and complete report. My realtor was very impressed, also. James is very trustworthy and has great customer service. I would not hesitate to recommend Over and Underwood Home Inspection to anyone needing an inspection."
