Impact Window Installation Cost - Written Price Before Anything Is Ordered

How Much Does Impact Window Installation Cost in Dallas?

Impact window installation in Dallas, TX typically costs $85 – $160 per square foot installed, with most whole-home projects falling between $12,000 and $38,000 depending on window count, size, and frame material. A standard 36″ x 60″ impact window runs roughly $900 – $1,600 including labor and materials. These figures reflect 2026 Dallas pricing for code-compliant, Miami-Dade or ASTM-rated impact glass from brands like PGT and CGI, which we install regularly across the metro.

What you’ll actually pay comes down to a handful of things: how many windows you’re replacing, whether they’re single-hung or casement, what frame material you choose, and whether the home sits in a flood zone requiring additional engineering. You won’t get a door-step surprise with us. Owen Satterfield and the Westlight Windows Dallas team put every price in writing before any work begins, and that number doesn’t move.

Before we get into the full breakdown, here’s what this guide covers: the current 2026 price ranges for Dallas, what drives cost up or down, where homeowners commonly overspend, and how to get a straight quote without the runaround.

Impact Window Installation Cost Breakdown (2026)

Here’s a direct answer for anyone researching Dallas impact window costs in 2026. These numbers are based on the jobs we quote and install across Dallas County, Collin County, and Denton County throughout the year.

These are installed prices, meaning the window, frame, labor, flashing, and basic trim are included. What they don’t include are structural repairs if the existing opening has water damage or rot, which is common in older Dallas homes, particularly in Lakewood, East Dallas, and the M Streets where many houses date to the 1950s and earlier.

The single biggest variable is frame material. Aluminum frames (the most common for impact windows in Dallas) run 10 – 15% less than vinyl, but vinyl offers better thermal performance in the summer and holds up better against Dallas hail. We carry both through PGT and CGI, and we’ll tell you which makes sense for your house rather than steering you toward the higher-margin option.

What Affects Impact Window Installation Pricing in Dallas

Dallas has its own pricing dynamics, and they’re not identical to what you’d see in Houston or San Antonio. Here are the factors that move the needle most.

• Window size and count. This is the biggest driver. A 24″ x 24″ bathroom window might be $500 while a large bay or picture window runs $2,500 or more. Whole-home projects with 15 or more windows typically get a better per-window price because mobilization costs spread thinner.
• Frame material: aluminum vs. vinyl. Aluminum is the workhorse in Dallas and runs lower up front. Vinyl insulates better against the 100° July heat that pushes through windows in Plano, Richardson, and Garland. We quote both and show you the payback difference.
• Impact glass rating. Miami-Dade rated glass (the strictest standard) costs more than ASTM-only rated glass. If you’re in a wind-borne debris zone or simply want the maximum protection for a home in Rowlett or Grand Prairie, Miami-Dade is the way to go. Most Dallas homes do fine with ASTM-rated impact glass from CWS or ES Windows.
• Home age and framing condition. Homes built before 1980 frequently have non-standard rough openings, rotted sills, or settling around the window frame. Repairing that adds $100 – $400 per opening. We encountered a 1962 ranch in Casa View recently where every south-facing window needed new sill framing. That’s the honest cost of doing it right.
• Installation method: retrofit vs. full replacement. Retrofit (pulling the old sash and installing the new unit in the existing frame) saves 20 – 30% compared to a full tear-out. But retrofit isn’t always possible, especially if the existing frame is aluminum and corroded. In Dallas’ clay soil, minor foundation movement can also make full replacement the smarter long-term call.
• Second-story or hard-access windows. Any window requiring scaffolding or ladder work on a two-story home in Frisco or McKinney adds labor. We’ll tell you exactly what that costs when we quote it, not after.

Is Impact Window Installation Worth the Cost in Dallas?

The honest answer: for many Dallas homeowners, yes. Here’s the math we walk through with customers.

Impact windows do three jobs at once. They stop wind-borne debris before it breaches the envelope of your home, which is the single most common cause of catastrophic storm damage in North Texas. They eliminate the need for exterior shutters or plywood, which a lot of homeowners in Dallas skip anyway because it’s time-consuming and looks bad. And they cut heat gain in summer and heat loss in winter. Some of our PGT and ECO Window Systems installations in Dallas have dropped summer cooling bills by 15 – 22% compared to older single-pane aluminum windows, which are still common in the mid-century neighborhoods of Preston Hollow and the Design District.

Insurance is the other piece. Many Texas carriers, including the big ones writing policies in Dallas County, offer hurricane or windstorm premium reductions for homes with certified impact glazing. We can’t promise a specific discount because every policy is different, but several of our customers in the Park Cities have reported 8 – 15% annual premium reductions after installing Miami-Dade rated impact windows from CGI. That adds up over the 20 – 30 year lifespan of the window.

You are not paying just for the glass. You’re paying for a window that stays in the frame when a tornado-warned storm rolls through, that keeps flying debris outside, and that doesn’t need caulking every two years. Whether that’s worth it depends on your home, where in the metro you live, and how long you plan to stay. If you’re in a rental or planning to sell within two years, the full ROI is harder to capture. If this is your long-term home in Dallas, the value is there.

PGT vs. CGI vs. Other Impact Window Brands: Dallas Pricing

We install from eight manufacturer lines because no single brand is right for every Dallas home. Here’s how the most common impact-rated options compare on price and performance in our market.

PGT is the volume leader, and for good reason. Their WinGuard line carries Miami-Dade ratings, comes in aluminum and vinyl, and prices 5 – 10% below comparable CGI products. For a standard 36″ x 60″ unit installed in Dallas, PGT typically lands between $950 and $1,450. PGT aluminum is a smart value for most single-story brick homes in Carrollton and Farmers Branch.

CGI carries a reputation as the premium option, particularly for coastal-rated glass. The frames are heavier, the tolerances tighter, and the price reflects it. Expect $1,150 – $1,700 per standard window installed. If you want the strongest possible window for a home near White Rock Lake, where wind funnels across the water, CGI is worth the step up.

ES Windows and CWS are mid-range, quality impact lines we stock for homeowners who want code-compliant protection without the premium brand markup. Standard windows run $850 – $1,300 installed. They install clean and look sharp in newer builds in Frisco and Prosper.

ECO Window Systems is where we go when energy efficiency matters most. Their impact-rated lines combine laminated glass with strong thermal performance, and they run about $1,000 – $1,500 per standard window installed. For a south-facing wall in a Dallas summer, the low-e coatings on ECO units genuinely help.

A word on brands we don’t carry: if a contractor quotes you a “marine-grade” or “hurricane window” from a brand you haven’t heard of, ask for the Product Approval number and check it against the Texas Department of Insurance windstorm program database. There are generic imports floating around Dallas that don’t meet Miami-Dade or ASTM standards, and they fail exactly when you need them.

Impact Window Installation vs. Standard Window Replacement: Cost Difference in Dallas

A standard double-pane vinyl replacement window in Dallas runs roughly $450 – $800 installed per window. An impact window of the same size runs $900 – $1,600. So you’re looking at roughly double the cost per window, give or take, with the gap narrowing on larger units and widening on smaller ones.

What that extra money buys you is the difference between a window that breaks when a 2×4 hits it at 80 miles per hour and one that catches that 2×4 in its laminated glass and keeps the opening sealed. Standard windows shatter into the home. Impact windows are designed specifically not to.

If your current windows are leaking, fogged, or original to a Dallas home built in the 1970s, the replacement decision gets easier. You’re replacing them anyway. The incremental cost of stepping up to impact-rated glass is around $400 – $700 per window, and for a full home that’s meaningful but not prohibitive. For many Dallas families, that’s the cost of not having to board up windows every spring and the cost of a cooler house all summer.

How to Save on Impact Window Installation in Dallas

Here’s what we tell neighbors who want the protection without overpaying.

• Replace in the off-peak season. Dallas impact window demand spikes in spring as storm season approaches. January through March and September through November are slower, and manufacturers run better promotions on PGT and ES Windows stock during those windows.
• Bundle windows with a door replacement. If you’re also replacing a front entry door or patio door, doing it in one scope reduces mobilization costs and lets us offer a better per-opening price. We routinely bundle impact windows with Therma-Tru entry doors for Dallas homeowners.
• Stick with standard sizes. Custom-sized impact windows carry a 20 – 40% premium. If your rough openings can accommodate a standard height and width without major framing changes, you’ll save real money.
• Focus on the most vulnerable elevations first. North and west-facing windows in Dallas take the worst of hail and wind-driven debris. If a full-home retrofit isn’t in this year’s budget, do the most exposed walls first and phase the rest.
• Get a written, line-itemed quote. Vague “window packages” hide soft costs. Every Westlight quote shows the actual per-window price, labor, permit line, and disposal, so you know exactly what you’re paying before any work starts. That’s the Kingswell Way.

And one more thing that saves money: not having to redo the work. The 365-Day Done Right Promise means if something’s not right within the guarantee period, we come back and fix it at no charge. No second invoice, no negotiation, no chasing a contractor who forgot your number. That alone is worth more than any $50 window discount.

Impact Window Installation Permits and Code in Dallas

Dallas requires a building permit for window replacement when the opening is being altered or when structural framing is involved. A straightforward same-size retrofit sometimes falls under a simpler permit path, but we handle the permit on every job where one is required, and the cost is line-itemed in your quote. Expect $150 – $600 depending on scope and number of openings.

Dallas also sits in a region where the Texas Department of Insurance windstorm program applies to certain designated catastrophe areas. Most of Dallas County does not require windstorm certification, but if you’re in a designated zone, your windows must be installed to TDI standards and the installer must be TDI-registered. We’ll tell you upfront whether your address falls in a zone and what that means for the project.

Building code in Dallas has trended toward higher energy performance requirements, including lower U-factor and SHGC ratings on replacement windows. All the impact lines we install, including PGT, CGI, ES Windows, and ECO Window Systems, meet or exceed current Dallas energy code. If your home is in a historic district, such as some pockets of Oak Cliff or Munger Place, additional design review may apply. We’ve worked through those processes and can tell you what to expect.

How We Price Impact Window Installation at Westlight Windows Dallas

Here’s the part most pricing guides skip: how the number actually gets built.

When you call us, a live person answers, 24/7. Not a voicemail tree, not a chatbot. That person schedules a site visit at a time that works for you. Owen Satterfield or one of our background-checked, uniformed technicians comes to your home in Dallas, measures every opening precisely, inspects the existing frames for rot or shifting, and talks with you about what you’re trying to solve. Is it storm protection? Heat gain in a specific room? Noise from a busy street in Lower Greenville? That changes the recommendation.

Then we write the price. Before any work starts, you get a written quote that itemizes each window, the frame material, the glass rating, the labor, the permit, and the disposal. That price is the price. The Kingswell Guarantee doesn’t allow for door-step revisions or “we found something once we opened the wall” surprises. If there’s genuine structural damage behind a window, we document it, we show you, and we get your written approval on any change before proceeding.

That’s the Kingswell Way, and it’s the same on every job we do: say the price before the work, show up in the window we gave, leave the place cleaner than we found it, put the guarantee in writing, and come back if it fails.

We’re an independently owned and operated Kingswell location, not a franchise with a corporate call center in another state. We’ve been doing this since 2009. The name comes from the west light, the late-afternoon sun that pours through a good window, bright and warm and worth doing right.

FAQs – Impact Window Installation Cost in Dallas

How much does one impact window cost installed in Dallas?

One standard impact window in Dallas runs $900 – $1,600 installed, depending on size, frame material, and glass rating. Smaller bathroom or utility windows can run as low as $500 – $700, while large picture windows or bay units run $2,000 – $3,000. Call (361) 441-0865 for an exact quote on your home. Estimates are free.

Is impact window installation cheaper than hurricane shutters?

Up front, no. Impact windows run $900 – $1,600 per opening installed while decent accordion or roll-down shutters run $350 – $700 per opening. But shutters require manual deployment before every storm, add ongoing maintenance, and don’t improve energy efficiency or home resale value. Over a 20-year span in Dallas, impact windows typically come out ahead.

Can I get impact windows installed in my Dallas home next week?

In most cases, yes for standard-sized windows from stocked PGT or ES Windows inventory. Custom sizes and CGI orders typically run 3 – 5 weeks from order to installation. Call (361) 441-0865 and a real person will check current Dallas inventory and schedule a measurement visit.

How much does a whole-house impact window retrofit cost in Dallas?

A whole-house retrofit in Dallas for 8 – 12 windows runs $12,000 – $24,000 installed. For 15 – 20 windows, expect $20,000 – $38,000. New construction with 20+ openings starts around $35,000 and goes up based on size and brand. Your written quote breaks down every window so you know exactly where each dollar goes.

Do impact windows lower my insurance premium in Dallas?

Texas carriers vary, but many offer windstorm or hurricane premium reductions for certified impact glazing. We’ve had Dallas customers report 8 – 15% annual premium reductions after installing Miami-Dade rated PGT or CGI windows. Check with your insurer for their specific discount schedule before you buy.

What’s the cheapest impact window brand for Dallas homes?

ES Windows and CWS offer the lowest entry price among the impact-rated lines we carry, typically $850 – $1,300 per standard window installed in Dallas. PGT runs slightly higher at $950 – $1,450. Cheapest isn’t always the right call, but if budget is tight and you want code-compliant protection, ES Windows is a solid starting point.

Is it cheaper to repair or replace an impact window in Dallas?

If the frame is intact and only the glass laminate is cracked, a glass-only replacement runs $300 – $600 per pane. If the frame is bent, corroded, or the window is 15+ years old, full replacement at $900 – $1,600 makes more sense. We’ll tell you honestly which path is right when we see the window.
