"This is the second time I have hired A-1 to perform a foundation check using a coupon I get from Angie's List. They take measurements in all rooms to see how much the foundation has shifted. A couple of days after the inspection I received an e-mail with a hand sketch of my floor plan and what the measurements were in each room. If I ever do have foundation problems I will be using this company."

"This company was by far the best company I have dealt with when it comes to foundation. I had seven estimates and I asked all of the companies to come and look at the opening to our crawl space before tunneling in to the side of my house and all refused. Kevin came out and assure me they could use the crawl space opening saving me $2000.00. Mariana was wonderful to deal with & always keeping me updated. I know they are busy because they are the best at what they do, FOUNDATION. I believe the job took longer than expected because of the tight crawl space but the foreman was great and I was not changed anything extra."

"Started to notice some signs of foundation settling (hard to close doors and subtle cracks along some interior and exterior walls) so I called A-1 to have someone come out and take a look. Kevin came out and was very cordial and friendly, even with a house full of people for the holidays. After completing his assessment, he told me what his findings were and reassured that there were no major issues. He even gave some advice on how to prevent issues and ensure a solid foundation in the future. Overall, I was very impressed with his knowledge and willingness to provide information on how to prevent a foundation failure."
