"Patrick was pivotal in credibly identifying safety, code, workmanship, quality, and structural issues on our home addition and garage project done by a Mason, Michigan builder who, despite being verified as licensed and insured with a 5 star review rating, proved to be a failure on all levels of home building. Until the inspection with Patrick of The Buyer’s Inspector, we had no idea how grossly misplaced our trust was in this builder. When COVID-19 shutdown our project we began noticing quality problems. This led us to hire Patrick from The Buyer’s Inspector. He was thorough, detailed, and spot on for the major problems as well as minor issues he identified during his inspection, including the multiple structural deficiencies. He recommended we hire a structural engineer to investigate these deficiencies in detail and the engineer verified all of Patrick's findings. It has been a very trying time legally fighting for our project to be done right but we thank Patrick for identifying all the problems using his extensive knowledge, experience, and understanding of Michigan's Building Construction Codes and industry standard building practices. Without his help we would have likely been stuck with this horrible build project that is riddled with safety, structural, workmanship, quality, and code issues. We highly recommend Patrick to anyone needing a thorough and detailed home inspection."

"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."
