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!
