"Installed a radon mitigation system. Explained everything to me before he started and also when the job was completed."

"the rep was knowledgeable and very conscientious. he answered my questions thoroughly and showed genuine concern about my situation and finances. And I got a callback to find out how things were going and lab reports were called to me and hard copies mailed to me in a timely manner. i felt i could trust him and would recommend him to anyone needing this service."

"Very professional and gave a good deal on price. Was able to do a radon inspection and inspect our house, shed, and pole barn all for 500 dollars. I caught a lot of things we could have missed. Great job!"

"Service was quick and efficient. We don't need to mitigate radon at the moment, but I was happy to get a quick turnaround on our results. I've already added SM Radon to my contacts for future testing needs."

"I hired Double Check to do an inspection for a personal decision of "Repair or Replace". Justin came out, performed the inspection, took photographs and answered all my questions. He found some issues like a few shingles missing, popped nailheads and the like. We discussed the Repair or Replace decision. Very knowledgeable and easy to deal with. Highly recommended."

"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."

"Brad was thorough, on time, and explained everything clearly. I felt confident in the inspection, and didn’t feel like he left any stone unturned. Would definitely recommend to anyone needing an inspection."

"Kase Dyksma was here on time as planned. He was very pleasant to talk to. He brought all the tools necessary including a ladder. He left no mess even when looking into the attic. When he finished Kase gave me a copy of the report and explained it. He gave me a pleasant good bye and was gone. Oh, he even loves dogs! He's the very best!"

"Mike and his daughter performed the inspections. He was responsive to my questions and doubts and was able to set up the appointment for the next day. I would have expected that the smoke detectors along with the doorbell to be tested - I didn't think of this until after the inspection. I did ask him to check some of the lights (porch, closet) that maybe would have been missed. Price was higher than most but he was able to accommodate my timing."
