My driveway had sunk almost 2 inches, making it difficult (and dangerous in the winter) to get the car into the garage. I called OCR and set up an appointment on July 10th (which was about a three weeks after my call). The guys showed up on time, set up quickly and finished the work efficiently. There is no drop between my garage floor and my driveway and everything is nice and even with a slight slope away from the house. I would recommend this company without any hesitation.
