Client Reviews

Dave,

Within hours of my initial call I was contacted by the coordinator. He listened to what was going on and dispatched a team that same day to save my door. I want to say the technicians names were Jeremy and Justin (please correct me if I'm wrong). Anyway, these guys truly represented your company well. They both had a zeal and passion for doing things the right way....Quality is not an act, it's an attitude and they both had it. In the end after ordering some parts and coming back out they had our door performing like it never had before. It's good to know that there are companies out there that stand behind their name even after their obligation was up.

Sincerely appreciate everything!

Hi Dave,

From my first contact with Jon to come out to look at the design and choices of your doors was a relaxed and productive experience. He is a pro and good person as well as being well informed with a sense of humor, that you can't find these days. Everyone is too uptight! The doors came in just as we thought, as scheduled, and the installation went very well, right after they arrived and taken off the truck. Their service is impeccable. Justin's crew are terrific. They are installation machines. They come in, remove the old doors, rebuilt the whole new configuration in a timely basis and were very informative about the new equipment. Excellent job of cleaning up as well. Very organized. Would highly recommend this company to those that want to spend their money wisely. Remember, you get what you pay for, and these doors are a high quality product. Harmon is the manufacturer. I can already feel the difference with insulated doors. It'll make a big difference in the winter Couldn't be happier!!!!!

Thanks,

-Steve S.
