After putting a bid down on a house I wanted, I had a local inspector thoroughly check through the house for any defects. He was unable to get a precise judgment on the foundation. I called the guys at D square to see if they could inspect the foundation for me. They came out the same day, for free. It was determined the the foundation was structurally fine. I was impressed with D-Square's customer service. Although things were fine and we didn't need their services, if we ever need a foundation company I would call them first.
