I used Perma-Pier to level one of my apartment buildings. Despite the building needing to be raised three inches, their crew started on Monday and was done by Friday. The job was completed in an efficient and organized manner. The crew was polite and respectful. They were as clean as they could be, considering the job they were doing. I had them leave the excess dirt and the crew spread it out in an eye-appealing way. I would recommend Perma-Pier to anyone.
