One of my overhead springs broke Monday morning on our large double door. I called to make an appointment for repair and was given a Friday appointment which concerned me as we could not open our door. I was advised that they would notifiy the team that if they had any slack in their schedules that came up I would be interested in getting the repair done. A couple hours later on Monday I was contacted and told that Leo has become availble and would I like him to repair the door. I said yes and Leo arrived about 30 minutes later. He assessed the situation and listened to all I had to say about the door and the components. He discussed the different components and their current shape and then constructed 3 repair options for me. I went with the one to replace the springs, cables, cable drums, and all the door rollers. Leo got to work and finished about 2 hours later and I now have a fully functioning and much quieter door. Leo brought terrific knowledge and a great attitude to the job. I'm very happy!

Another 5 Star service experience from Precision Garage Door!! Our technician Leo called ahead of schedule to let us know when he would arrive. He did a fantastic job replacing our old opener. He explained what was wrong with the old unit and reviewed options for a replacement unit. The installation went smoothly and after the installation he went over the new system with us. The new unit works perfectly. We are very happy with our new garage door opener.

The spring mechanism on my garage door broke, I called Precision Door Service, who responded almost immediately. Leroy came out, was extremely courteous and helpful discussing my options. I opted to have a torsion spring mechanism installed. It's much quieter than my previous mechanism and works perfectly. While he was installing it, Leroy cleaned out my somewhat dirty tracks and ensured everything worked smoothly. All done within the 90 minutes he estimated.

The entire process was as easy as it gets. From making an appointment, to the communication from the Technician Leo about when he would arrive. As I was not home, Leo reached out after evaluating my problem and thoroughly explained a few options for the repairs I needed. I ended up needing to replace a few components as it was pretty old (1996). During the repair/replacement he kept me updated and again reached out when he was all done. Sent me over the invoice for me to look which was easy to read and understand and everything was broken down so I could see what I was spending my money on. When I arrived at home that section of the garage was cleaner then I left it and everything was installed very nicely. My garage door finally does not wake the whole neighborhood or shake my house anymore. I could not be happier with the job. I highly recommend this company and even more so Leo.

Precision garage company sent one of their best technician to fix my garage door. His name is Leo Mr. Leo was professional timely and so very nice. He took his time to make sure he assessed everything and then fix the door. Also gave me a nice quote for a new door. If I decided to get one, I would recommend this company to anyone they would be pleased.

Precision personnel came out on time and were extremely knowledgeable regarding the issues we were having. I was told the new garage door would take 6 weeks to order; however, they would be able to repair the existing door so that we can utilize it over the six week period waiting for the new one to be installed. That was the best news as we utilize the garage door probably more than other people. Thanks to Leo and his helper for doing such a fantastic job fixing the current door. I would highly recommend Precision Garage Door for any garage door repair/replacement!

Very easy to make an appointment on line. Leo was great. He called to let me know he was on his way and was on time. He was friendly, knowledgeable, and professional. He had even looked up our record with the company. He quickly repaired our garage door so it was easier to open and gave us options to consider for the future. I can definitely recommend Precision Garage Door Service.

Leo was the best. He installed our garage door several years ago and came back to install a new one. Very thorough with explanation of charges and also with set up of remotes and keypad. We are three time return customers and highly recommend to anyone.

We were very happy with the service we received today. Our garage door was opening and closing unevenly. The problem was immediately diagnosed. Our options were explained clearly and we decided, on the spot, (which is very rare for us) and an hour later the door rolls quietly and smoothly. We were not pressed into doing more with the door than needed and we appreciated that. I would definitely recommend this company.
