I would like to thank you for the outstanding service I received from your company. Your technician, James, was friendly, courteous, and extremely knowledgable about what needed to be done to return my garage door to a safe operating condition. In addition, the service was completed within 24 hours of my request, at no additional cost. I enthusiastically recommended Precision and will definitely contact you in the future should I require garage door service!
I'm not a professional, but I watched as my garage doors were serviced last year. The tech used a spray lubricant (I had bought a different brand in the garage door section of a home improvement store). He sprayed the inside of the entire track, top and bottom, the rollers that ride along the track, and all hinges on the door. He sprayed each hinge twice -- once on each side. The techs were more generous with the lubricant than I was when I'd done it before, so don't be afraid to give it a good squirt.
