Don't bother, sales guy is super rude. "We only work with contractors" Another way he could have went about that is, here are some contractors we work with. I will NOT recommend to anyone!

At times, no live person is available to take calls AND the voice mail boxes are full. A contractor ordered a door through them and the order numbers were mixed up so now were back to the bottom of the production schedule. Placed order with the contractor in April and will not see a door until late July or August? Ouch! Don't care how many years they have been in service, the owners need to redirect their organizational focus as it's been lost. Ensure that you review other companies.

These guys were great to work with and I love our new door! They had a lot of patience while I kept going back and forth with what I wanted and were also very good about making sure I knew all of the factors that needed to be considered when ordering the right dimensions. I mostly worked with Sonny, who was very responsive and helpful. The door I ordered had some special features that you can't just get anywhere.vented sidelights! Worth the extra $$. Thanks, Colonial!
