Window Company in Duncanville, TX
Duncanville’s brick ranch homes from the 1960s through 1980s were built for a different Texas. Single-pane aluminum windows that sweat in winter and bake in August, hollow-core doors that warp by July, and hail season every spring. Our window and door work here starts with that reality. We’re Westlight Windows & Doors, an independently owned and operated Kingswell location, and every Duncanville job gets a written price before any work begins. Call (361) 441-0865 and a real person picks up, day or night.
Why Duncanville Homes Are Different
Most Duncanville houses in neighborhoods like Greenbriar, Fairmeadows, and the original streets off Center Street carry their original window frames. That means aluminum sashes that conduct triple-digit heat straight into the living room, condensation dripping onto sills during cold snaps, and frames so out of square they rattle when the wind picks up. The North Texas climate punishes that hardware: triple-digit summer days, humidity that never quits, and spring hailstorms that test every pane and panel.
Duncanville’s severe hail and summer heat drive most of our calls here. Homeowners replace failed windows with low-e glass (a thin coating that reflects heat back into the room in winter and out in summer) and double-pane assemblies that cut the solar load. Front doors are another story: original wood doors in Duncanville swell and stick in the humid months, then shrink and leave gaps in winter. We match the right product to the house, not the other way around.
Our Main Duncanville Services
Three jobs account for most calls from Duncanville homeowners. Each has its own page with pricing, timelines, and the local conditions that shape the work.
Window Replacement in Duncanville
Older Duncanville homes often have windows sized to 1960s and 1970s rough openings, which means replacement is rarely a simple swap. We measure every opening, check for rot or shifted framing, and order the exact size rather than forcing a stock unit into place. Hail damage and failed seals show up most often on west-facing walls, where the late-afternoon sun beats hardest. The full breakdown, including what a typical project runs in Duncanville, is on Window Replacement in Duncanville.

Window Installation in Duncanville
New construction, additions, or swapping a small window for something larger all fall under installation. In Duncanville that often means cutting into brick, which takes a careful hand and the right flashing to keep water out of the wall cavity. We pull permits where the city requires them and bring every opening to code. Room-by-room expectations and prices are covered in detail on Window Installation in Duncanville.

Door Installation in Duncanville
Entry doors in Duncanville take a beating: direct sun, hail, humidity swings, and brick settling that shifts the frame over decades. A door that sticks in August or shows daylight at the threshold in January isn’t just uncomfortable, it costs money on every utility bill. We install exterior and interior doors measured to the rough opening, shimmed square, and sealed against air and water. See the specifics on Door Installation in Duncanville.

What Duncanville Customers Say
"Front door was swollen and wouldn't latch half the year. New door and frame, done in a day. Looks great and actually seals. Written price didn't budge."
- Renee Saldana"Replaced eight drafty old windows that were basically single pane. The house is warmer already and the street noise is way down. Crew was on time both days and the price was exactly the quote."
- Harold Bemis"Our energy bill in summer was brutal. New windows made a real dent in it. Salesman wasn't pushy and didn't do the fake "today only" discount thing the others tried."
