"April helped us line up a last minute inspection for a new build for us. They were extremely thorough and found a few significant problems that we were able to take to the builder. They included lots of photos of the issues which was helpful. They used thermal imaging too which was new to us but helps detect problems that may not have been seen otherwise. We got our report along with a summary the next day and had excellent communication and follow through. We will definitely use them in the future and highly recommend."

"Needed fencing installed to keep groundhogs from taking up residence under our deck. Brady came up with a creative and complete solution that made sure the varmints were out and would not return. Would use again."

"I had done some self testing so was aware that work was needed. SWAT got back to me within minutes of making my selection. The appointment was within days. The technician was very clear about options of placement. I had already upgraded the fan and outside pipe. He went to work and did a neat job. The best part is that my tester indicates that radon has almost disappeared."
