Read Customer StoriesPick the door by how you use the opening.
A front entry, a back patio and a garden room each ask something different of a door. We compare entry, French, patio and storm options with you and match each one to the traffic, light and security that opening needs.
Entry doors for the street
Woodgrain front doors set the tone for the house, in a wood, glass and panel mix you pick.
French doors for daylight
Hinged French doors open wide to the yard and can swing in or out to suit the room layout.
Sliders for tight patios
A slider saves floor space because it opens along its own track instead of swinging into the room.
Storm doors as a shield
A storm door adds triple weatherstrip and a three-point lock in front of the door you already have.

(210) 796-9574The cost to replace an exterior door depends on the door type, material, glass, hardware and whether the frame is replaced too. A slab-only swap costs less than a prehung door with a new frame, and fiberglass, steel and decorative glass options vary widely in price. A measured, itemized quote shows exactly what is included.
Yes, you can replace just the door slab if the existing frame is square, solid and free of rot. When the frame is damaged, out of square or leaking, a prehung door that includes a new frame is the better choice because it seals properly. Inspecting the frame and threshold determines which option fits your doorway.
Fiberglass is the most versatile exterior door material for most homes because it resists dents, rot and humidity and can mimic wood grain. Steel is strong and secure but can dent and rust if the finish is damaged. Wood looks classic but needs regular refinishing, especially on doors that face strong sun and heat.
Exterior door installation time depends on whether you replace the slab or the full frame, the door type and how much trim, threshold and hardware work is needed. Custom sizes or decorative glass also add ordering time before install day. Your schedule is confirmed before work begins, so you know what to expect from start to finish.
Yes, a new exterior door can improve energy efficiency when it has an insulated core, tight weatherstripping and a properly sealed threshold. Older doors often leak air around worn seals or warped frames. Doors with glass should use insulated Low-E glass to limit heat gain in Texas sun, and ENERGY STAR labels make options easier to compare.
The main types of replacement doors are entry doors, French doors, sliding patio doors and storm doors. Entry doors focus on security and curb appeal, French doors swing open in pairs, patio doors slide to save floor space, and storm doors add a protective outer layer. Our San Antonio team can help you compare them for each doorway.
