The entire experience was excellent. I needed a spring repaired, but other components were also old, compromised, and in need of replacement. Leo was very communicative and patient with all my questions. He presented my options clearly and did the work in an efficient and professional manner.

Following a power outage my door opener stopped working. The technician came and condemned the "board" due to a suspected power surge. Subsequently the door started functioning again following another outage (way to go PECO). My concern is that the board was condemned (for $300+) without testing for power cycling. I'm left with the worry that this will happen again. Understand that I am not faulting the technician, but he as well as I should have tried to power cycle the unit.

Your technician Leo was absolutely amazing. He was able to provide 2 new remotes and pair my car’s opener. Leo was prompt, courteous, thorough and very knowledgeable. Leo also provided an estimate for a new motor as my opener is getting quite old. Old fashioned 5 star service! Leo is certainly an asset to your company!

We are pleased with the service we received. The call center rep was courteous and explained the costs. The technician arrived early within the given time window. (We were fortunate to receive same day service). He clearly explained our options and costs. He was extremely courteous and provided excellent service. We chose Precision based on a hunch after previewing several ads. Precision’s just stood out. I recommend their service for any garage door needs.

Precision Door is a top notch company. They installed garage doors in two homes and the work was perfect. When I did have an issue of our own making (kid backing up and damaging the door), they were out the next day, repaired the door and offered options for replacing damaged section if we did not like the cosmetic damage. Very professional and easy to deal with!

The technician was super communicative and very friendly. He was incredibly knowledgeable and timely. I believe he did a quality job in a very timely manner and helped us out where he could. I was a little shocked that it was over 400 dollars to replace a spring, I understand there was a minimum for the work he could do and I understand that's just what it costs. But that did hurt. Everything is expensive these days I suppose. Thankyou for the excellent job done.
