"Bob and his crew did a great job. From dealing with the office staff from the first call all the way until job completion I was impressed with the service. Not only that he had the best quoted price as well and while this may not seem like a big deal there were a few factors that made this impressive. First he was coming from further away than any other company, a lot further, over an hour away. Next he quoted the job site unseen and found that a portion of the work he quoted was already done when he arrived onsite so after the lab test came back showing everything within acceptable ranges he surprised me with a refund for that portion of the job that he didn't have to perform."

"If you’re looking to get any type of inspection or home services then look no further. I recently became a customer of Justin Ake after trying to get my soon to be home inspected. Rick was dispatched to the property and went above and beyond, both explaining the inspection process and showing me key points in the houses plumping and drainage systems. As well as providing information on other tests and services the company performs. I don’t normally write reviews, but I have to say this is one business that takes pride in their trade."
