Single & Double Hung Windows in Dallas, TX
Single and double hung windows are the most common window style in Dallas homes, and for good reason. Both types have an upper and lower sash, but the difference is simple: single hung windows have a fixed top sash and only the bottom sash moves, while double hung windows let both sashes slide up and down. Westlight Windows Dallas offers Window Installation Near Me in Dallas, TX for both styles across the metro, from Lakewood to Plano to Frisco, and we start every job the same way: a written price before any work begins.
If you’re replacing windows in an older Dallas home, chances are you already have single hung windows, since they were the builder standard for decades. But many homeowners upgrade to double hung when they learn the price difference is often smaller than expected. Call us at (361) 441-0865 and we’ll walk you through both options. You can also learn more about our full range of services on our Window Installation page.
The name Westlight comes from the late-afternoon sun that pours through a good window: bright, warm, and worth doing right. That’s the standard Owen Satterfield holds every installation to, whether it’s a single bedroom window in Oak Cliff or a full-house replacement in Carrollton.
How Much Do Single & Double Hung Windows Cost in Dallas?
Most single and double hung window replacements in Dallas run $450 to $900 per window installed, depending on size, frame material, glass package, and whether the opening needs any repair work. A typical three-bedroom Dallas home with 10 to 12 windows usually falls in the $5,500 to $10,800 range for a complete replacement.
Here’s a closer look at what drives the price:
- Vinyl frames: $450 to $700 per window installed. The most popular choice in Dallas; good insulation, low maintenance, and the best value.
- Fiberglass frames: $700 to $1,100 per window installed. Stronger and more dimensionally stable than vinyl, which matters in Dallas where summer heat can make cheaper frames warp.
- Wood or wood-clad frames: $800 to $1,500 per window installed. Common in older homes in Highland Park and University Park where the look matters more than the price.
- Low-e glass upgrade: Adds $40 to $90 per window. Low-e is a thin coating that reflects heat back into the room in winter and out in summer. In Dallas, where July and August push triple digits, this is the single best upgrade you can make.
- Impact-rated glass: Adds $150 to $400 per window. We carry PGT and CGI impact lines for homeowners who want storm protection without shutters. North Texas hail makes this worth serious consideration.
Those ranges are real numbers from Dallas jobs, not national averages pulled from a pricing website. Labor in the Dallas-Fort Worth metro runs higher than smaller Texas markets, but nowhere near what you’d pay in coastal cities. The important thing to know: you’ll get your exact written price before we order a single thing, because that’s how we operate. No door-step surprises, no revised invoice after the fact.
Single Hung vs. Double Hung: Which One Should You Choose?
The short answer: if you’re replacing windows in a one-story home and you never open the top sash, single hung saves you about $40 to $80 per window. If you want the option to ventilate from both sashes, double hung is the better call, and the price gap has narrowed to the point where most Dallas customers choose double hung.
Here’s the breakdown:
- Single hung: Bottom sash moves, top sash is fixed. Slightly cheaper, slightly fewer moving parts, slightly easier to maintain. Still a solid, honest window.
- Double hung: Both sashes move and both tilt in for cleaning. More ventilation control, which matters in a Dallas spring when you want airflow without running the AC. Also easier to clean from inside, which matters on a second story.
- Energy efficiency: Essentially identical when both have the same glass package. The frame and installation matter more than the hung style.
- Resale: Dallas buyers lean toward double hung, but the difference is marginal in an appraisal. Buyers care more about whether the windows are new and sealed than whether both sashes move.
When You Need Single & Double Hung Windows
Here are the signs Dallas homeowners notice first:
- Your windows are painted shut. This is common in pre-1990 homes across East Dallas and Richardson. Layers of paint seal the sash to the frame, which kills ventilation and makes the window useless in an emergency escape.
- The sashes won’t stay up. Worn-out balances in old single hung windows mean the bottom sash slowly slides down. You prop it open with a stick or a book. That’s not a quirky old-house thing; that’s a failed mechanism.
- You feel a draft or see sunlight around the edges of the sash. The weatherstripping and glazing in Dallas windows break down faster because of the heat. If you can feel air moving on a windy day, your window is leaking conditioned air year-round.
- Condensation forms between the panes. That means the seal has failed and the insulating gas has escaped. The window is now just two pieces of glass with humid air between them, and no cleaning will fix it.
- You can hear everything from the street. Single-pane windows, common in Dallas homes built before the 1980s, do almost nothing to block traffic noise from Central Expressway or Mockingbird Lane. New double pane windows with the right glass package make a measurable difference.
- You’re planning to sell. Dallas buyers notice windows. If yours are foggy, drafty, or painted shut, they’ll ask for a credit. Replacing them before listing lets you list at full ask instead of negotiating down.
Dallas Climate and What It Means for Your Windows
Dallas summers are brutal on windows. June, July, and August regularly push past 100°F, and the sun beats on the west side of your house for hours every afternoon. That heat is exactly what the name Westlight refers to: the late-afternoon sun that pours through a good window. But a bad window, with failed seals or no low-e coating, turns that afternoon light into a heat pump pointed at your living room.
Your Awning & Hopper Windows and other window choices in Dallas should be driven by two things: solar heat gain and durability in heat. Low-e glass, which we install standard on most Dallas jobs, reflects heat back outside in summer and keeps it inside in winter. We also stock energy-efficient ECO Window Systems glass packages that are tuned for hot climates like North Texas, not just generic double-pane glass.
Hail is the other Dallas factor. Spring storms roll through with marble-sized and sometimes golf-ball-sized hail, and windows with old, brittle glazing are the first to crack. If you’re replacing windows anyway, consider impact-rated glass from PGT or CGI. It adds cost up front, but it beats the alternative: a broken window in the middle of a spring storm and a tarp over the opening until we can get there. We answer the phone 24/7 for exactly that scenario.
Our Single & Double Hung Windows Process
We call it The Kingswell Way, and it applies to every window job, from a two-window bedroom replacement in Garland to a 30-window whole-house project in Allen. Five promises, every single job:
- We say the price before the work. When we come to your Dallas home, we measure every opening, check for rot or damage, and put the total price in writing before we order anything. Not an estimate that might change; a written price.
- We show up in the window we gave. You’ll know when we’re coming. Not “sometime Tuesday.” A real arrival window, and we hit it. If something changes, a real person calls you.
- We leave the place cleaner than we found it. Window replacement generates dust, old caulk, broken glass, and debris. Our uniformed, background-checked technicians clean as they work and do a final walkthrough before we leave. You shouldn’t find a stray shim in your flower bed three days later.
- We put the guarantee in writing. Every customer gets a written guarantee at job completion. It spells out exactly what is covered and for how long. No verbal promises, which is what a lot of window contractors in Dallas lean on.
- We come back if it fails. If something goes wrong within the guarantee period, we come back and correct it at no charge. That’s the 365-Day Done Right Promise and the Free Second Visit promise, and they’re both automatic. You don’t need to negotiate, escalate, or threaten a bad review. You call, we fix it.
On the product side, we install windows from eight manufacturer lines, including 3-Panel Sliding (3-Lite Roller) Windows, ES Windows, ECO Window Systems, and Mr-Glass. That means we match the product to your house and your budget, instead of forcing your house to fit whatever single brand we happen to stock. A 1960s ranch in Richardson needs something different from a 2000s build in McKinney, and carrying multiple lines lets us be honest about what works.

FAQs – Single & Double Hung Windows
How much does it cost to replace a single hung window in Dallas?
Replacing a single hung window in Dallas typically costs $450 to $700 for a standard vinyl unit installed, and $800 to $1,500 for wood-clad or specialty sizes. The price depends on the opening dimensions, frame material, glass package, and whether there’s any rot or framing damage behind the old window. We measure, assess, and give you a written price before ordering anything, so there are no surprises on install day. Call (361) 441-0865 for an exact quote; estimates are free.
Is it cheaper to repair a window or replace it?
It depends on the failure. If the issue is a broken balance, a worn sash cord, or caulking, a repair often costs $150 to $350 and makes sense. If the glass seal has failed, the frame is rotting, or the window is 20-plus years old and drafty, replacement usually makes more financial sense. In Dallas, where heat accelerates seal failure, most window issues in homes built before the 1990s point toward replacement rather than repeated repairs. We’ll give you an honest assessment either way.
Can you install double hung windows in an older Dallas home?
Yes, and it’s one of the most common upgrades we do in East Dallas, Oak Cliff, and Richardson, where older homes were built with single hung windows. The rough opening usually works for a double hung unit, often with minimal trim work. The main consideration is the frame material and glass package, since older Dallas homes benefit from modern insulation and low-e glass. We’ll walk you through exactly what changes and what stays the same before you decide.
Can you come today?
For a free estimate, we can often schedule you quickly; for a full window replacement, we order the windows to your exact measurements, which usually takes one to three weeks depending on the product line. If you have a broken window or a security problem, call us and a live person will answer 24/7, and we’ll get someone to your Dallas home as fast as we can. Call (361) 441-0865 and we’ll tell you exactly what to expect.
What’s the difference between single hung and double hung windows?
The difference is that single hung windows have a fixed upper sash and only the bottom sash opens, while double hung windows let both the upper and lower sashes slide independently. Double hung windows also tilt in for easy cleaning from inside your Dallas home, which matters on second stories. The price difference is small, and most Dallas homeowners choose double hung when they compare both options side by side.
Why Dallas Homeowners Choose Westlight Windows Dallas
We know what it’s like to be burned by a contractor. The no-show. The price that jumped at the door. The window that fogged up six months after the installer disappeared. Owen Satterfield started Westlight Windows Dallas in 2009 as part of the Kingswell network of independently owned and operated locations because the window business had a habit of making promises it didn’t keep.
So we built the company around writing everything down. The price, the arrival window, the guarantee. If we say we’ll be there Tuesday between 8 and 10, we’re there. If the seal fails within the guarantee period, we come back and fix it at no charge. That’s not a sales pitch; it’s the 365-Day Done Right Promise, and it’s printed on the guarantee we hand you when the job is done.
We also answer the phone. A live person, 24 hours a day, 7 days a week. Not a voicemail that goes to an inbox nobody checks. If you have a broken window at 9:00 PM on a Saturday in Plano, you call and a real human picks up. That’s rare in this business, and we know it’s why our customers stick around.
If you’re ready to talk about replacing your single or double hung windows in Dallas, call us at (361) 441-0865. We’ll schedule a free estimate, measure your openings, and give you a written price before you spend a dime. Whether you’re replacing one window or a whole house full, you’ll know exactly what it costs and exactly what you’re getting. That’s how it should work.
