I brought them out in 2016 because I was continuing to have foundation issues after another company had worked twice on my home. Kevin came out and said I didn't need foundation work. He recommended I add foundation watering and pointed to a tree in the back yard as drawing water from under the foundation. First I had automating watering installed around the foundation. After waiting a year to see if that corrected my issue, it stopped getting worse, but didn't get better. At that point I broke down and had the tree removed. Within a year almost all the cracks had closed, and doors were working smoothly. I just recently had them out again to see if anything needed doing as I prepare to do some improvements to the home. Keven showed me exactly how my home had improved, comparing old readings to current. We could see how the opposite side of the house had significantly improved from the foundation irrigation and the foundation near the tree had totally recovered. He stated the minor issues I had left did not indicate a need for foundation work. It's a pleasure to work with someone who will give you good advice that doesn't always lead to spending money.
