Most window and door work in Castle Hills comes down to one thing: homes built in the 1950s and 60s are still carrying their original single-pane aluminum windows, and the Texas sun has not been gentle with them. We’re Lightwell Windows & Doors, part of the Cedarwell network since 2010, and we focus on replacement and installation work that fits Castle Hills’s mid-century ranch and traditional homes. Seals fail, frames fade, doors warp, and homeowners are left with rooms that never quite hold a comfortable temperature. If you’re weighing your options, call us at (325) 420-4173 and we’ll walk through what your home actually needs.
Why Castle Hills Homes Are Different
Castle Hills is a compact, established community, and the housing stock reflects it. The predominant homes are single-family ranches and traditional builds from the mid-20th century, which means window openings, door frames, and trim profiles were sized for materials that are no longer standard. That matters when a replacement has to match the original look while meeting today’s insulation and weatherproofing expectations. Hot, humid summers and relentless UV exposure accelerate seal failure, fade painted frames, and warp wooden doors, and the occasional hailstorm adds glass and screen damage to the list. Homes here face real conditions that generic products do not always handle well.
Drive along Cantwell Drive or Castle Hills Drive and you’ll spot original jalousie windows, the angled glass slats that were popular decades ago. They leak air constantly and cannot be insulated the way a modern double-pane unit can. Replacing them changes both the comfort and the energy profile of the home, but the work has to be measured and ordered carefully because those openings were never built for standard replacement sizes. Castle Hills jobs reward a crew that takes the time to get the measurements right the first time.
Styles & brands we work with
Our Main Castle Hills Services
The two calls we hear most from Castle Hills homeowners are about replacing windows that have failed and installing doors that no longer seal or swing true. Each service has its own detailed page, linked below, so you can read exactly what applies to your situation.
Window Replacement in Castle Hills
Most replacement work in Castle Hills starts with Windows from PGT, Mr-Glass, and ViewLux, chosen because they hold up to South Texas sun and humidity. The typical job involves removing an original aluminum or jalousie unit, correcting any rot or settling around the opening, and setting a properly flashed, insulated replacement. For older ranches, we often find the original frame was never sealed against driving rain, which is why interior drywall stains show up years later. See the full scope, including what gets protected inside the home, on the Window Replacement in Castle Hills page.
Window Installation in Castle Hills
New window installation in Castle Hills usually happens when a homeowner is adding a room, converting a porch, or finally replacing a jalousie unit with a solid, energy-rated window. The work has to match the home’s mid-century lines while meeting current code for egress, flashing, and insulation. Castle Hills’s older framing sometimes means the rough opening needs correction before the new window goes in. We cover the full installation process, including cleanup and the final inspection, on the Window Installation in Castle Hills page.
Door Installation in Castle Hills
Entry doors, storm doors, and patio doors in Castle Hills take a beating from sun on the west-facing sides of homes. Warped slabs, failed weatherstripping, and loose thresholds are common, and a door that does not close cleanly is also a security concern. We install Therma-Tru and other brands that hold their shape in heat and humidity, and we take care to preserve the trim and flooring around the opening. Read the specifics on the Door Installation in Castle Hills page.

Prices in Castle Hills push higher when a home still has original jalousie openings, because the rough opening usually needs reframing to accept a standard unit. Rotted trim and out-of-square frames on 1960s builds add labor too. Whatever the job, you get a written price before any work starts, so the number on the invoice matches the number you approved.
