They arrived on time, were very professional and left the house as clean as when they first started.

The tech drove out to inspect my property on a Saturday morning. He was very courteous and professional, and quickly assessed the cause of my foundation problem, and described possible solutions in a very clear manner.

We have no complaints at all. As far as we can tell, they did a good job, were punctual and professional. (One of our checks sent to them was lost and we had to put a "stop payment" on it. They reimbursed for the stop payment charge. So far, the check has not been found. It did get to their office as they had made a copy of it. We had to issue another check. I am uneasy about this lost check being "out there" somewhere. Otherwise, no complaints at all!)

When the contractor gave me the quote he also explained how they were going to do the job. They were scheduled to be out the following week, but they called me after 2 days and said that their crew had finished their current job early and asked if they could get started right away. They were at my house that same afternoon. The guys in the crew were personable and explained to me what they were doing whenever I asked.

They were quite thorough, did a great job and the foundation is now FLAT! I particularly enjoyed working with their sales and support staff. And the fact that they use their own work crews was the deciding factor.
