Window Company in Dallas, TX
Window and door work in Dallas comes down to one reality: our housing stock was built for a different climate than the one we’re living in now. Tens of thousands of brick veneer homes from the 1950s through the 1990s still have their original aluminum single-pane windows, and Dallas summers expose every weakness those frames have. Seals fail, glass fogs, frames warp, and the afternoon heat finds its way inside. We’re Westlight Windows & Doors, an independently owned and operated Kingswell location, and we handle window replacement, window installation, and door installation across Dallas with written pricing before any work starts. Call (361) 441-0865 and you’ll get a real person, not a voicemail box.
Why Dallas Homes Are Different
Dallas’s retrofit market is shaped by two forces: the age of the housing stock and the severity of the weather. The brick veneer tract homes that fill neighborhoods like Lake Highlands, Casa View, and Red Bird were built fast between the 1950s and 1990s, mostly with aluminum windows that were never meant to last forty or fifty years. Today those frames are corroding, the single panes are doing nothing against the July sun, and the weep holes that should drain rainwater are clogged with years of sprinkler spray and hard-water scale. In Lake Highlands and Richardson especially, we regularly find original aluminum frames so corroded at the weep holes that a full frame replacement is the only honest fix, not a pocket insert. Add in the hail cycles that sweep through Dallas every few years, and a lot of homeowners are discovering real damage during re-roofing projects that was hiding behind old window screens. The good news: the right replacement glass changes how the house handles summer. High-SHGC low-e coatings reflect heat back out while still letting in the west light that gives us our name.
Our Main Dallas Services
These are the three jobs Dallas homeowners call us about most. Each has its own detailed page with pricing, timelines, and what to expect.
Window Replacement in Dallas
Most Dallas replacement jobs involve pulling aluminum or wood originals out of brick openings and setting in new units that actually seal. In older brick veneer homes, we check the condition of the rough opening and the brick mold before we quote anything, because thirty years of Texas sun and sprinkler spray can rot the wood buck behind a frame that still looks fine from the street. We carry eight manufacturer lines, so the conversation starts with what your house needs rather than what one brand happens to sell. Read the full breakdown on our Window Replacement in Dallas page.
Window Installation in Dallas
New-construction installs and additions have their own set of Dallas-specific concerns. Flashing details matter here, because spring storms and the occasional hurricane remnant push more water at a rough opening than you’d think. We install everything from standard double-hungs to large fixed picture windows for custom builds in the northern suburbs, where high window-to-wall ratios make glass selection a real performance decision. See how we handle the details on the Window Installation in Dallas page.
Door Installation in Dallas
Entry doors in Dallas work hard. They get direct afternoon sun, they get slammed by the same storms that kill roofs, and they’re often the first thing a buyer notices in a resale. We install fiberglass and steel entries from brands like Therma-Tru, plus patio and sliding doors that need to hold a seal against hundred-degree heat. A door that’s hung slightly out of plumb in Dallas will bind worse every summer. Get the details on our Door Installation in Dallas page.

Prices in Dallas push higher when the existing frame has hidden rot, when the opening is out of square (very common in 1970s brick work), or when the home needs impact-rated glass to handle hail exposure. Whatever the number turns out to be, you’ll have it in writing before we order a single part. We don’t revise quotes at the door.

Our crews work across the whole of Dallas, from the older brick subdivisions east of White Rock Lake out to the newer builds in Far North Dallas and south to Oak Cliff and Red Bird.

FAQs About Window Company in Dallas
Most estimates happen within a week of your call, and we try to schedule a committed arrival window rather than a vague “sometime Tuesday.” Actual installation dates depend on product lead times, especially for impact-rated glass, but we keep a running stock of common sizes in the Dallas-Fort Worth office to shorten waits. Call (361) 441-0865 and we can give you a realistic timeline.
Many Dallas HOAs, especially in places like Lake Highlands and Far North Dallas, have architectural review processes that require window style and material approval before work starts. We’ll help you identify what your HOA needs and make sure the products we quote meet their standards. It’s one less thing to fight after the fact.
Every job comes with the Kingswell Guarantee in writing and our 365-Day Done Right Promise. If something isn’t right during the guarantee period, we come back and fix it at no charge. If a repair fails, you automatically get a free second visit. We don’t make you negotiate for it. Call (361) 441-0865 to set up your free estimate.”

What Dallas 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."
