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.

Always professional, knowledgeable, and clear. Good quality, done quickly. Prices seem amazingly high, but that’s the world we live in today.

Leo did a great job!! I got a new remotes, new opener, spring replaced, rollers replaced, keypad, Leo did a great job explained to me how a garage door worked. He explained to me exactly what he was gonna do before he started. He went over a great detail how to use the new opener and the remote and the keypad. Also, all the aspects of the new stuff that he put in place. it is so wonderful to have somebody come in. Do a great job. Explain everything and have a smile the whole time I wish I could run into more repair people like Leo.

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.

Leo was a polite and courteous technician. There was no clean up necessary after his work was completed and he was transparent about the work necessary on the garage door.

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!).

We had service call today and the technician's name was Leo. He was very professional and explained the condition of our garage door and what improvements could be made. We only replace the rollers which improve the noise issue greatly. We will wait until later to do more repairs or replacement. We were very pleased with the service. Thank you

My experience with Precision was a very positive one. It began with Beth, who answered the phone. Ever so pleasant and efficient, she was able to schedule me for same day service for my problem. She explained the visit fee and gave me the name of the service technician. She also answered any questions I had. Leo, the service technician, was scheduled to come between 1 and 3. He called earlier and asked if he could come at 12:15. He was prompt, courteous and eager to answer my questions so that I could understand what happened to the opener. He showed me a problem he noticed with my springs and cables (23 years old) which were headed for breakage (even I could see that) and gave me several options to defer the breakage. I am totally satisfied with the service Precision performed and would recommend them.

Hi Keith - Today, Thursday, 12/11/2025, I brought my trash cans in and went to close my garage and heard some squeaks and it wouldn't close. I called your business and spoke with Beth who was able to fit me in on your busy schedule which my family and I are very grateful for. Leo called said he'd be out in 20 minutes which he was. Leo was extremely professional. He said he has been doing this job for over a decade. He showed and explained to me fully my options. I called my wife Sharon at work and also my neighbor who is handy Federico came over and Leo explained the options again in full taking the time for us to make the right decision. Leo got the job done in a timely manner and showed me the work performed. I couldn't ask for more. I will recommend Precision to all my neighbors and friends. Thanks again and Happy Holidays.

I have been using Precision Door Service for over 8 years in our Chester County and Bucks County properties. They are always friendly, on-time and professional. We just had an older motor replaced in our Coatesville house. They arrived on time and explained everything to me and even setup the connection on my phone for me. If anyone needs any type of service to their garage doors, I highly recommend them.
