Quality Construction: The Key to French Doors

How To Choose a French Door

THRESHOLD

Look for a well-designed threshold that will keep water away from the door and outside the house, where it belongs. You’ll also want to make sure that the doors close snugly, keeping out drafts and outside noise.

HINGE

True French doors are hinged, allowing homeowners to choose between outswing or inswing styles. The hinges should also be adjustable to account for the doors settling over time. The beauty of French doors depends heavily on their symmetry, which means there would be nothing worse than off-kilter French doors

SPACE

If you don’t really have the wall space for doors that swing out or swing in, you can still have quality French wood patio doors. Gliding French doors are the perfect solution for homeowners looking install them but don’t have much space or resources to follow through.

"Loved working with Custom Exteriors. Very responsive to inquiries. Precise in their measurements, estimate and timeframe for completion. Highly recommend them."

Brian I.

Tampa, FL

"Custom Exteriors provided a great product and good service in replacing 2 sliding glass doors and 2 other windows in my townhouse. One was a custom window that required extra work in refitting the plantation shutters to the new window. Although there were some bumps along the way, Jeff and his foreman Ryan excelled at follow up. I would recommend Custom Exteriors."

"Custom Exteriors did a wonderful job. The installation crew were neat and thorough. My salesman Mark kept me informed about delivery and the windows are beautiful, quiet and warm house. I’m very pleased."

"Kevin one of the owners of Custom Exteriors contacted me the following day and immediately tried to make things right. The first thing, I was impressed about was he took my call without hesitation. Many medium sized business will bounce me around to different people before finally being able to talk to the owner. He was an attentive listener and took to the time understand my needs and wants in an exterior entry door.His communication was top notch, sending me estimates the same day or the following day. He gave me choices in fiberglass doors: ProVia and Therma-Tru, hardware: Trilennium vs Emtek, and single point vs multiple point locks. I just ordered a ProVia doors through Kevin. This surprised both to my husband and me. Before contacting Custom Exteriors, we thought we were going to get a Therma-Tru door, but that totally changed once we the information we needed from Kevin. I get the sense that he truly wants to give customers options and information, but respects the customer's final decision. There is not high pressure sale pitch. Kevin wants customers to be informed and happy with the end product."
