Bring your measurements and we'll help you find a door that fits. If your opening is an odd size, the mill shop can modify and customize one.

Fiberglass or wood

Fiberglass doesn't warp or rot the way wood can. Therma-Tru Classic-Craft adds composite rails and hardwood edges against moisture.

Simpson makes contemporary doors in nearly any wood species and glass type. For wood, see how to select a wood exterior door.

We cut doors down, re-rail them and mortise hinges.

Note the width and height in inches.

Add 2 inches to the width and 2 1/2 to the height.

Bring that rough opening to the showroom.

How do I figure out the rough opening?

Add 2 inches to the door's width and 2 1/2 to its height. A 30 by 80 inch door needs a 32 by 82 1/2 inch opening.

What are french doors used for?

They come as a pair and open an extra-wide doorway, mostly onto a patio. Contact us to talk sizes.

Where can I see the full catalogs?
