The integral horizontal reinforcing trusses and dual seals between the sections are just two of the standard features that set them apart from other doors available on the market today.

Custom finishes are also available.

“I am a happy customer”

We had a broken spring that was repaired by another company. Within 2 weeks, they had to come back, and when it broke again, we called Durham Garage Doors. The problem is fixed, Jason was awesome and the price was right. I'm a happy customer :o))
