Review:

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.

Review:

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.

Review:

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!

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.

As a repeat customer with Precision Door, I have had nothing but the best experiences with this company. Both Tina and Leo have presented themselves with nothing but the top professionalism and politeness when they have come to my home. Each time, the work that was done, was thorough and top notch. There will never be any other company that I use besides this one.

Review:

Terrible communication. Just another private equity backed company (KKR) that over charges. They show up with their iPads and oversell you on products you probably don’t need. Reiterating terrible communication skills. They slap a sticker on your garage wall immediately upon arrival, without asking. Find a local business do not use a neighborly company like precision garage door.

We called Precision Door after seeing an ad. They had a local office so we booked an appointment. The technicians arrived in the scheduled time window, and corrected issues on both our garage doors. We are happy with the results and would recommend them to all our neighbors (already have!).
