Window Company in Kirby, TX
Window and door work in Kirby, TX centers on one reality: this city of roughly 9,000 people, tucked just northeast of San Antonio, was built largely between the 1950s and 1970s, and many of those original windows and doors are still in place. That means single-pane aluminum frames, hollow-core doors, and seals that gave up years ago under South Texas heat. We’re Juniper Windows & Doors, and we handle replacement and installation work across Kirby with written pricing before anything starts. Call (903) 488-7019 to schedule a free estimate.
Why Kirby Homes Are Different
Kirby’s housing stock skews compact: single-story ranch and traditional homes on modest lots, often with brick veneer or hardboard siding. The original windows in these houses were built for a different era. Single-pane aluminum, narrow openings, shallow wall depths. None of that holds up well when July temperatures sit in the upper 90s and humidity never lets up. We routinely see failed seals, warped frames, and rusted hardware from years of condensation and UV exposure. Homeowners here tend to know exactly what they’re dealing with because the heat makes it impossible to ignore. Energy bills climb, rooms never quite cool, and windows sweat or stick. Kirby jobs are usually retrofits, not new builds, which means matching existing trim, working around stucco, and fitting modern glass into openings that were never designed for it. The local soil and weather also mean expansion and contraction cycles that test every installation. We’re used to it.
One more thing worth knowing: many Kirby homes still have jalousie louver windows on porches or utility rooms. They’re period pieces, and they leak air like a screen door. Replacing them with insulated vinyl units while preserving the shallow wall depth is a job we handle regularly. It’s not the kind of work a generalist gets right on the first try.
Our Main Kirby Services
Window replacement and door replacement are the two calls we get most from Kirby homeowners, but window installation work on additions and remodels keeps us busy here too. Each service has its own Kirby page with pricing and details.
Window Replacement in Kirby
Replacing windows in Kirby usually means pulling original aluminum or wood frames out of a 1960s ranch and fitting something that actually blocks heat transfer. We measure carefully because older Kirby homes often have non-standard openings, and we match the stucco trim so the finished job looks like it belongs. Low-E glass and tight weatherstripping make an immediate difference in rooms that bake in the afternoon sun. Learn more about Window Replacement in Kirby.

Window Installation in Kirby
For additions, sunrooms, or new construction in Kirby, window installation is about getting the rough opening right the first time and flashing it so South Texas thunderstorms never become an indoor problem. The jalousie-to-insulated swap on porches and utility rooms falls under this work as well. We coordinate with the framing and trim stages so the job moves without delays. Learn more about Window Installation in Kirby.

Door Replacement in Kirby
Hollow-core doors from the Nixon era don’t seal, don’t insulate, and don’t do much for security either. Kirby door replacement jobs typically focus on exterior doors: front entry, back door, and garage-to-house transitions. We address rusted thresholds, warped jambs, and weatherstripping that’s turned to powder. Learn more about Door Replacement in Kirby.
