Wonderful service so far! Timely - earlier than I expected! I was clearly informed about the situation and my options which helped me making my final decision. I hope everything will be fine and will get my new garage door properly installed soon, as we agreed!

The appointment window was 8 to 11 AM. Leo was here at 8 AM sharp. He had the problem identified quickly and had it repaired in 20 minutes. This was my first time using Precision Door. However, I will definitely be using them in the future and recommend them to my neighbors.

They installer did not have model 8355 I ordered to replace my older but working unit . He talked me into accepting model 8550 with WizFi. He did not activate the WiFi and simply left me a printed manual.

I have used precision door now for several years. Most recently to install 2 new doors tracks and motors. They have arrived promptly every time and the technicians are courteous, personalable and exceptionally well trained. Leo Cornelius is the technician for my area and is a true professional. He is very knowledgeable and does a great job troubleshooting door issues. I rarely write reviews but Precision Door deserves to be recognized because they are just that much better than the rest.

Keith and his guys are tremendous. I found them when my old door became inoperable and they sold me a new door, and everything associated with it, at a very reasonable price and they came when they said they would and communicated with me all along the way and generally exceeded my expectations. Very competent and honest! I recently had a keypad stop working and they were out the next day and fixed it in no time at all. I highly recommend them!

Although I would rather not have had to call Precision because my old door opener short circuited due to lightning ,I was glad that I did. The tech that came out to see me was very courteous and preformed his job quickly. I had to replace the old opener and Precision helped me to do that very quickly and painlessly. I am happy with the liftmaster WiFi door opener that was installed. Precision is a top notch company and I would recommend them to anyone with garage door opener problems. This was a very unwanted and unexpected expense, Precision explained all of my options and the tech was very transparent with the costs involved. Well Done guys!!
