"We thought we had foundation problems and contacted CNT for an estimate on repairs. ED VanOsdol came out at the specified
time to give us a quote. Ed generated a computerized lay out of the structure of the house and then crawed under the house and made pictures of the structure. He indentified one problem area which was minor and a potential problem area. He explained
what was happening to the foundation and because it was so minor, he told me how I could fix it myself. I told him that I would
pay for the inspection, but he said it was not necessary. If I ever do have problems with my foundation, I will certainly use them
for the repairs. I would recomend CNT to everyone. They are very professional and honest.

"I was really under the gun due to a prior Architectural firm not performing their duties per building plan codes. Not only were the plans incomplete but the City Plan Reviewer states(The Worst plans he’s ever seen) they will not make adjustments unless there is an additional charge for Thousands. Evaluation’s saved my clients and drew our project per code, along with Engineering in less time then they quoted. I highly recommended them, Especially Kirsten. You went above and beyond trying to coordinate this project. The staff was very professional and I will use them on all my projects. Sincerely, Frank B BCM Builders"
