New Window Installation Cost - Written Price Before Anything Is Ordered

How Much Does New Window Installation Cost in Dallas?

New window installation in Dallas typically costs between $450 and $1,400 per window installed, with most homeowners paying $6,000 to $14,000 for a full-house replacement of 10 to 15 windows. The single biggest variable is the window material: vinyl runs $450 to $800 per window, wood runs $800 to $1,400, and impact-rated aluminum from brands like PGT or CGI starts around $900 and goes up from there. Labor in Dallas typically accounts for $150 to $300 per opening, and you should expect a 2 to 4 week lead time for product ordering before installation day.

Those numbers are real Dallas numbers, not national averages. Our installers work in neighborhoods from Lakewood to Frisco to Arlington every week, and we quote against what this market actually charges. The good news: you can get a written price before any work starts, and that price should not change at the door. That is the Kingswell way, and it is how we have operated in Dallas since 2009.

New Window Installation Cost Breakdown (2026)

Here is what you should expect to pay in the Dallas market this year, broken down by window type and material. These ranges include the window unit, installation labor, basic trim work, and haul-away of the old window.

That is the window itself. Add $100 to $250 per opening if you are also replacing interior trim or casing, and another $75 to $150 per window if lead paint testing or abatement is required. Houses in Dallas built before 1978, common in East Dallas, Oak Cliff, and parts of Richardson, may hit that lead issue.

Full-house jobs often come in lower per window than singles because setup, staging, and cleanup get spread across more openings. A 15-window replacement in a 2,200-square-foot home in Plano or Carrollton might run $9,000 to $16,000 all-in, while swapping out 5 windows in a Preston Hollow ranch could land between $3,500 and $6,500 depending on the product line you pick.

What Drives Cost Up or Down

Vinyl is the most affordable material and the most common choice in Dallas. Wood windows, which many homeowners in historic districts like Swiss Avenue and Munger Place need for aesthetic and code reasons, cost substantially more both up front and over the life of the window. Aluminum is the go-to for impact-rated products, which are mandatory in some newer builds and increasingly popular with homeowners who want real storm protection, not just code-compliant glazing. The trade-off is price: impact-rated PGT or CGI windows run $900 to $1,600 per opening installed, but they are built to withstand debris at 140 mph and can cut wind insurance premiums meaningfully in Dallas County.

What Affects New Window Installation Pricing in Dallas

• Window material. Vinyl is the budget-friendly standard. Wood costs 60% to 90% more and requires maintenance. Aluminum, especially impact-rated, sits at the top of the price range but earns back value in durability and insurance savings.
• Glass package. Low-e glass (a thin coating that reflects heat back into the room in winter and out in summer) adds $40 to $90 per window, but in Dallas it is the single best upgrade for energy bills. Double-pane argon-filled is now standard for most brands, including ECO Window Systems and ES Windows.
• Impact rating. If you want or need windows that meet Miami-Dade and Texas Department of Insurance standards for windborne debris, expect to pay 40% to 70% more per window. PGT and CGI are the two impact-rated lines we carry and install most often in Dallas.
• Window size and shape. A standard 36×60 double-hung in Carrollton is a different bid than a 6-foot picture window in a Lake Highlands living room. Odd shapes, arches, and oversized units all push labor and product cost up, sometimes steeply.
• Age and condition of the opening. If the existing frame is rotted from Dallas humidity or termite damage (common in older Oak Cliff and East Dallas homes), the carpenter must rebuild the rough opening before the new window goes in. That adds $150 to $400 per window, and you find out only when the old window comes out. Our written price covers what we can see; if hidden rot appears, we stop, show you, and agree on a change order before any additional work.
• Second-story and access. Upper-floor windows need ladders, scaffolding, or lift work, which adds labor cost. In some Dallas neighborhoods with tight setbacks or mature trees, access can get tricky. We quote the access cost up front, not as a surprise line item.

How to Save on New Window Installation

You don’t save money by finding the cheapest bid; in Dallas, the cheapest bid usually means low-grade vinyl, rushed labor, and a company that won’t answer the phone in March. You save money by avoiding rework and by making smart product decisions.

Replace now if your seals are gone. A failed double-pane seal means the argon has escaped and the insulating value has dropped. Waiting doesn’t make the window cheaper; it makes your energy bills higher. Dallas summers punish inefficient glass, and July is the worst month to discover a budget window can’t keep up.

Choose vinyl unless you have a reason not to. For most Dallas homes, vinyl from a reputable manufacturer like ECO Window Systems or Mr-Glass delivers the best balance of price, energy performance, and longevity. Wood windows are beautiful, but they are a premium product with a premium maintenance burden. Unless you are in a historic district or really want that wood interior, vinyl is the value play.

Consider full-frame replacement only when you need it. Insert or pocket installation, where the new window fits into the existing frame, costs less than full-frame replacement. But if the frame is rotted or you’re changing window styles, full-frame is the honest fix. We’ll quote what the job actually needs, not what makes a bigger invoice.

Bundle the project. Replacing 12 windows in one go costs less per window than replacing 2 windows three times over six years. You pay for setup, mobilization, and haul-away once instead of three times.

Get a written price before you commit. This is the single most important step. At Westlight Windows Dallas, you get your price in writing before any work starts. No door-step revisions, no “we found something unexpected so the price changed” phone call after demo starts. Owen Satterfield built this company on the principle that the price you agree to is the price you pay. Call (361) 441-0865 and we’ll schedule a free estimate.

Can You Install New Windows Yourself in Dallas?

You can, and some homeowners in Dallas do tackle simple vinyl replacements on ground-floor windows with standard rough openings. But here is what we see: DIY window installation mistakes show up as air leaks, water leaks, and fogged glass within the first year, and a botched install voids the manufacturer’s warranty. On second-story windows, especially with the steep roof pitches common to Dallas mid-century homes, a fall from a ladder is not worth the $150 to $300 per window you would save in labor. Window installation is not inherently dangerous like high-tension garage springs or electrical work, but incorrect flashing around the opening will let water into the wall cavity, and that repair costs far more than professional installation ever would have. If you install a window and the flashing fails, you are fixing framing, drywall, and possibly mold, not just the window.

How Westlight Windows Dallas Prices a Job

We follow what we call the Kingswell Way. It is five promises, and every one of them is in writing before a single screw turns.

• Say the price before the work. Your written quote is your price. Not a ballpark, not a maybe, not a “we’ll see when we get in there.”
• Show up in the window we gave. You get a real arrival window, and our background-checked, uniformed technicians show up in it. Calls are answered by a live person 24/7, so if something shifts, you’ll know before we’re late.
• Leave the place cleaner than we found it. Old windows out, new windows in, debris hauled away, glass vacuumed, sills wiped. Every job, every time.
• Put the guarantee in writing. You get a written guarantee on the completed work at job completion, not in an email three weeks later.
• Come back if it fails. Under our 365-Day Done Right Promise, if something is not right within the guarantee period, we come back and fix it at no charge. And if a repair fails, the second visit is free too, automatically, no negotiating.

We carry eight manufacturer lines: PGT, CGI, CWS, ES Windows, ECO Window Systems, Mr-Glass, Therma-Tru, and ViewLux. That matters because the right product gets matched to the job, instead of the job being forced to fit whatever single brand a contractor happens to stock. If you need impact-rated windows for storm protection, we’ll show you PGT and CGI. If you want a mid-range vinyl with solid energy performance, ECO Window Systems. If you’re replacing the front door at the same time, Therma-Tru is the entry-door brand we trust.

The name Westlight comes from what late-afternoon sun does through a good window: bright, warm, and worth doing right. That light is the point of the whole project. The price is the honest cost of letting it in.

How Much Does New Window Installation Cost in Dallas? (Neighborhood Pricing Notes)

The Dallas market is not one market. It is a patchwork of neighborhoods with different housing stock, different code requirements, and different price expectations.

In Preston Hollow and Bluffview, homes tend to be larger and the window packages premium. Expect $1,000 to $1,700 per window for high-end vinyl or wood on a 3,000-square-foot home. In Lake Highlands and Casa View, mid-century ranches dominate, and the standard job is 10 to 12 double-hungs with aluminum frames original to the house. Those projects often run $7,000 to $12,000. In Oak Cliff and Kessler Park, older homes, historic district rules, and mixed framing conditions push the per-window cost higher, especially when wood windows are required to match original architecture. In Frisco, McKinney, and Prosper, newer construction means fewer rotted openings but larger window counts: 15 to 20 windows in a 3,500-square-foot home is common, with full-house bids from $10,000 to $22,000 depending on product.

This is a useful starting point, but it is not a quote. The only number that matters for your home is the one we put in writing after we measure the openings and check the framing. That estimate is free, and it takes about an hour.

FAQs – New Window Installation Cost

How much does window installation cost per window in Dallas?

Window installation in Dallas costs $450 to $1,400 per window installed, with vinyl at the low end, wood in the middle, and impact-rated aluminum from PGT or CGI at the top. Labor typically runs $150 to $300 per window, and the window unit itself accounts for the rest. A written quote from Westlight Windows Dallas gives you the exact price before work starts, and it will not change at the door.

Is it cheaper to repair or replace a window in Dallas?

In Dallas, repairing a single-pane window with a cracked glass unit runs $150 to $450, while replacing the whole window runs $450 to $1,400. Repair makes sense when the frame is solid and the only problem is the glass. Replacement makes sense when the seal has failed, the frame is rotted, or the window is more than 20 years old and the energy savings of new low-e glass will eventually cover the difference. Call us at (361) 441-0865 and we’ll help you decide honestly, even if the answer is that repair is the better move this year.

How long does new window installation take in Dallas?

Product ordering takes 2 to 4 weeks for most window lines, including PGT, CGI, and ECO Window Systems. Installation day itself is fast: a crew of 2 to 3 technicians can typically install 8 to 15 windows in one day, depending on access, framing condition, and whether full-frame replacement is involved. The entire project from signed quote to finished install usually runs 3 to 5 weeks in the Dallas market.

Do I need a permit for new window installation in Dallas?

In the City of Dallas, a permit is generally required when the window opening size changes, not for like-for-like replacements that fit the existing rough opening. Many of our Dallas jobs, however, fall under city or HOA requirements that vary by neighborhood, and historic districts like Swiss Avenue have additional review layers. We handle permit paperwork for you when a permit is needed, and we tell you up front if your project is going to need one.

What is the best time of year to install new windows in Dallas?

The best time to install windows in Dallas is fall (September to November) or early spring (February to April), when weather is mild and crews are not booked out as far. Summer installation is fine but unpleasant for the crew and your air conditioning, and late spring is the busiest season for window contractors in Dallas. Winter is the slow season, which sometimes means slightly better pricing and faster scheduling, though December and January are less common install months.

How much can new windows save on energy bills in Dallas?

For a typical 2,000-square-foot Dallas home, replacing single-pane aluminum windows with double-pane low-e vinyl windows cuts cooling costs by $300 to $600 per year, depending on your current windows and how much you run the AC (which in Dallas is a lot). Impact-rated windows with insulated glass packages can push that savings higher while also reducing the stress on your HVAC system during July and August. The savings alone rarely justify the full cost of replacement, but combined with comfort, noise reduction, and resale value, the investment usually pencils out over the life of the window.
