We’re Lightwell Windows and Doors, and we handle window replacement, window installation, and door installation for Kirby homeowners. Kirby’s housing stock – mostly 1950s to 1970s ranch homes on tight lots – means window work here rarely follows a standard playbook. Side setbacks are narrow, foundations are slab-on-grade, and many homes still have original single-pane aluminum frames that were never designed for the humidity and hail cycles we get in this part of Texas. If you’re weighing new windows or an exterior door in Kirby, call us at (325) 420-4173 for a free estimate and a written price before anything starts.
Why Kirby Homes Are Different
Kirby sits in a pocket of Bexar County where post-war builders prioritized speed and simplicity. The result is a grid of single-story ranch and minimal traditional homes on 0.2 to 0.4 acre lots, with brick veneer or wood siding, shallow slab foundations, and windows that sit close to property lines. That last detail drives a lot of what we do here. On many Kirby streets, a side-facing window is only a few feet from the neighbor’s exterior wall. Exterior installation – where the crew works from outside and replaces the whole frame – is often physically impossible. We use interior-set and pocket replacement techniques instead, removing the old sash and trim from inside the home and setting the new window into the existing frame. This protects the exterior brick, avoids disturbing the shallow foundation, and keeps the whole job contained within the lot line.
Kirby’s climate adds another layer. Hot, humid summers and occasional severe thunderstorms with hail put real stress on window seals and door weatherstripping. Homes without deep roof overhangs – and many Kirby ranch homes were built with minimal eave protection – see caulking and glazing degrade faster than shaded homes in older San Antonio neighborhoods. What works for a two-story home on a wide lot doesn’t always apply here, and we plan every Kirby estimate around the actual house in front of us, not a generic checklist.
Styles & brands we work with
Our Main Kirby Services
The two calls we get most from Kirby are for replacing aging windows that have lost their seal or struggle to open, and for exterior doors that no longer sit square in their frames after years of heat and settling. Below are the three Kirby pages with the full details.
Window Replacement in Kirby
Most Kirby homes still have their original single-pane aluminum windows, and by now the frames are pitted, the tracks are worn, and the glass does almost nothing to block heat or sound. Replacement here usually means measuring each opening individually because framing on these 1960s and 1970s homes was rarely square to modern tolerances. We remove the old sash from inside, set the new unit, insulate around the frame, and trim out the interior cleanly. See the full breakdown on our Window Replacement in Kirby page.
Window Installation in Kirby
New construction and addition work in Kirby has a different profile than replacement – you’re often working with fresh framing, but the same tight setbacks and slab foundations apply. We coordinate with your builder or handle the full install ourselves, including flashing, sealing, and interior trim. Custom sizing is common because Kirby lots don’t leave room for stock window sizes in every wall. Learn more about the process on the Window Installation in Kirby page.
Door Installation in Kirby
Kirby’s clay-heavy soil expands and contracts with moisture, and over decades that movement pushes door frames out of square. A new door here often means more than swapping the slab – we check the rough opening, repair or replace the jamb, and set the new door with proper shimming so it closes without dragging. Exterior doors also take the brunt of Kirby’s sun exposure on west-facing walls. See specifics and pricing on the Door Installation in Kirby page.

What pushes a Kirby job higher is usually custom sizing – original rough openings on these older ranch homes rarely match today’s stock dimensions. Interior-set work on a tight side lot adds some cost per opening but avoids the bigger expense of exterior masonry repair. Every estimate comes as a written line-item price before any work begins, and that number doesn’t change at the end of the job.
