Best Preventative Maintenance Repair in Phoenix AZ

At first, it seemed like I was getting a good job, for a steep price, which I did not mind. The job was completed. Jim's workers were pleasant but they did not do the job properly. They also did not do what they had promised to complete. There were portions of the floor that were just awful and you could see the sanding circles. Also, they were suppose to leave me a pint of the concocted color ( which was a blend of other colors) they did not. I have called twice and Jim has not returned my calls. I would suggest to go elsewhere. Thank you
