New entry and patio doors in New Braunfels, TX: handling afternoon sun on back doors, door styles, rentals near the river and simple draft fixes.
Spend a July afternoon on a west-facing patio in New Braunfels and you'll understand why the back door matters as much as the front one. A lot of homes here are built around the backyard, with a big slider or a pair of French doors opening onto the patio. That's great for cookouts. It's also a big sheet of glass catching the hottest sun of the day.
An older sliding door with clear double-pane glass can let in a surprising amount of heat. You feel it on the floor in front of the door and in an AC that runs longer every afternoon. Newer patio doors use low-E glass with a lower solar heat gain coefficient, and the difference is easy to notice when you stand next to one.
Check the frame, too. Old aluminum frames conduct heat right through to the inside, and you may see them sweat on humid mornings. Vinyl, fiberglass and thermally broken aluminum frames all do better.
Whatever style you pick, the opening has to be flashed correctly. Water that gets past the sill can quietly rot the subfloor for years before anyone notices.
New Braunfels has plenty of homes where the front door is part of the style: arched tops, stained wood, decorative glass. You don't have to give that up to get a door that seals well. Fiberglass doors come with realistic wood grain that takes stain, and they won't warp or crack in the sun the way solid wood can.
If you want glass in or beside the front door, look at privacy glass options and low-E coatings. A sidelight on a west-facing entry can heat up a foyer fast.
If you own a vacation rental near the Comal or the Guadalupe, your doors take a different kind of beating. Guests come and go all day, let doors slam and prop them open with coolers during tubing season. A few things help:
Before you replace a door that's leaking air, check the weatherstripping, the sweep and the threshold. On a bright day, turn off the lights and look for daylight around the edges. If you can see it, air is getting through. New weatherstripping and a sweep cost little and take an hour or so.
If the door still leaks after that, or the frame is soft or water-stained at the bottom, replacement is the better fix.
Prices move with size, material, glass and how much work the opening needs. As a rough guide, a standard fiberglass front door, prehung in a new frame and installed, often lands somewhere between $1,500 and $4,000, with decorative glass and sidelights pushing it higher. A quality vinyl sliding patio door is often in a similar range. Hinged French doors and multi-slide systems climb from there, sometimes by a lot, because the opening may need a new header or reframing.
