Updated for 2026. Authorized installer of Pella, Andersen, Marvin, and ProVia, serving Austin, San Antonio, and the Hill Country.
A full-home window replacement of 15 to 20 windows in Austin or San Antonio runs $20,000 to $35,000 in 2026 for mid-tier vinyl. Premium fiberglass like Marvin Elevate or Pella Impervia runs $23,000 to $42,000. Wood premium like Marvin Ultimate, Pella Reserve, or the Andersen A-Series runs $32,000 to $70,000+. Per-window pricing for individual replacements typically runs $700 to $1,200 (vinyl), $1,200 to $1,800 (fiberglass), and $1,800 to $3,500+ (wood). All ranges include installation, trim, low-E glass package, and proper waterproofing. Financing: 6.99% APR for 180 months or 0% APR for 18 months.
Windows are where Texas heat, UV, and wind exposure meet some of the most expensive openings in your home. A well-installed modern window can drop your peak summer cooling bill by 15 to 25%, eliminate condensation damage on sills, dampen Austin and San Antonio street noise, and pay back its premium over its lifetime. A poorly installed window (or the wrong product for the climate) leaks air, fogs between panes, and fails inside 8 to 10 years.
JP Exteriors is an authorized installer for every major North American window brand: Pella, Andersen, Marvin, and ProVia, plus Texas-popular vinyl lines like Simonton, MI, and Burris. We bring product samples to every estimate so you can compare profile, glass package, hardware, and finish side by side before committing.

All prices below assume a full-home replacement of 15 to 20 windows including installation, exterior and interior trim, waterproofing flashing, low-E glass package, and proper insulation around each frame.
Window Line | 2026 Cost Range | Best For |

Which Window Material Should You Choose for Central Texas?
For roughly 75% of Austin and San Antonio homeowners replacing original-builder windows, mid-tier vinyl from Pella Encompass or Simonton is the right call. You get strong U-factor and SHGC numbers for our climate, a lifetime frame warranty, and a price point that respects the math of a 15 to 20 window full-home project. We install hundreds of these systems a year across Cedar Park, Round Rock, Pflugerville, Hutto, Buda, and San Marcos.
The next tier up is fiberglass from Marvin Elevate or Pella Impervia, which is the right choice for Hill Country custom homes and substantial remodels in Westlake, Lakeway, Spicewood, Steiner Ranch, Alamo Heights, and Stone Oak. Fiberglass expands and contracts almost identically to glass, which eliminates the seal-stress that contributes to vinyl frame failure in the Texas summer. Expect a 30 to 50% premium over premium vinyl.
Wood windows are the choice for historic Central Austin homes (Travis Heights, Hyde Park, Old West Austin) and for ground-up Hill Country custom builds where the look of authentic wood is non-negotiable. Marvin Ultimate, Pella Reserve, and the Andersen A-Series are the standard specifications. Expect a 60 to 120% premium over premium vinyl. See our window style guide for detail.
Glass Packages, Low-E Coatings & Pane Counts
The glass itself is often the most overlooked decision in a window project, and it can move the energy and comfort performance of your home more than the frame material does. Three things to understand:
Glass Spec | What It Does | Texas Recommendation |
|---|---|---|
Double-pane vs. triple-pane | Triple-pane improves U-factor and sound dampening | Double-pane is standard. Triple-pane pays off near busy roads or for sound-sensitive bedrooms. |
Low-E coating | Reflects infrared heat. Multiple coats available (low-E2, low-E3). | Low-E3 (south and west elevations) is the right call in Central Texas. |
Argon or krypton gas fill | Inert gas between panes slows heat transfer | Argon is standard in every mid-tier and above unit. Krypton is overkill for our climate. |
Tinted or laminated glass | Adds privacy, UV protection, security, hurricane resistance | Useful for west-facing rooms with sun fade or ground-floor street-facing windows. |
Energy Efficiency & Texas Climate
Window performance is graded on two numbers in our climate. U-factor measures heat transfer through the frame and glass (lower is better). SHGC (Solar Heat Gain Coefficient) measures how much of the sun's heat enters through the glass (lower is better in Texas, since we want to keep the sun's heat outside). The ENERGY STAR target for South-Central Texas is U-factor ≤ 0.30 and SHGC ≤ 0.25. Every window line we install meets or exceeds this, and many of our fiberglass and composite premiums perform significantly better.
What does this mean in dollars? On a 2,500 sq ft Austin home with original single-pane builder windows from the late 1990s, full replacement to a modern low-E double-pane vinyl typically drops the summer cooling bill by 20 to 30%. We document expected savings in our written proposal. The payback period on the energy difference alone usually lands between 8 and 12 years, with the comfort improvement (no more hot spots near west-facing windows, no more cold drafts in winter) starting on day one.
What Moves Your 2026 Window Price
1. Window Count
This is the dominant factor. Pricing scales nearly linearly with the number of openings. Most Austin and San Antonio homes have 15 to 20 windows. Hill Country customs and larger Stone Oak builds frequently have 25 to 35.
2. Material & Brand Tier
As shown above, going from builder-grade vinyl to wood premium can triple your project cost. Material is the choice that drives the budget.
3. Opening Size & Configuration
Standard double-hung and single-hung windows price predictably. Larger picture windows, custom-sized arched windows, oversized casements, and bay or bow combinations add cost per unit. Egress windows in basements or bedrooms have minimum size requirements that can drive cost up.
4. Existing Frame Condition
We perform two install types. An insert (retrofit) install replaces the sash and glass unit only when the existing frame is sound. A full-frame install replaces the entire frame when it's compromised by rot, leak history, or termite damage. Full-frame installs cost 25 to 60% more per opening and are usually required on 1970s to 1990s Central Texas homes with original wood frames.
5. Trim & Finish Scope
Standard installs reuse existing interior casing where possible. Projects involving custom interior trim, exterior brick mold replacement, or stucco and Hardie patch work add scope. We document this explicitly in every proposal.
6. Multi-Story Surcharge
Two and three-story window replacements carry a 10 to 17% surcharge for access and safety setup.
Brand Notes: Pella, Andersen, Marvin, ProVia
Pella
Pella is the most-installed window brand in our 2026 book across the Encompass (mid-tier vinyl), 250 Series (premium vinyl), Impervia (premium fiberglass), Lifestyle Series (composite), and Reserve (premium wood) product lines. See our Austin Pella window page. Pella's lead times are competitive and their replacement-specific products are engineered for the retrofit scenario.
Andersen
Andersen 100 Series Fibrex composite is one of the best-performing window materials in our climate. It's better than vinyl in heat cycling, with comparable pricing to premium vinyl. The A-Series wood is the choice for high-end remodels. See our Andersen window page.
Marvin
Marvin Essentials, Elevate, and Ultimate represent the most architecturally refined options in our lineup. Ultimate (wood) is the gold standard for new construction and full historic-style remodels in Westlake, Tarrytown, and Alamo Heights.
ProVia
ProVia is increasingly chosen for premium replacement windows. The Endure and Aspect vinyl lines and the Aeris composite line carry industry-best warranties and a level of finish detail typically reserved for higher-priced brands.
2026 Window Pricing by Service Area
Window pricing holds steady across our Central Texas footprint with the standard mobilization and complexity adjustments at the edges. Here are local context pages:
Austin Metro Notes
Central Austin neighborhoods like Hyde Park, Travis Heights, Old West Austin, Crestview, and Allandale are dominated by 1940s through 1970s homes with original single-pane wood-frame windows. These usually require full-frame replacement and frequently benefit from wood or fiberglass for architectural authenticity. Suburban Austin (Cedar Park, Round Rock, Pflugerville, Hutto) is dominated by 1990s through 2000s production homes with original builder-grade vinyl, which means straightforward insert replacements with mid-tier vinyl or fiberglass.
San Antonio Metro Notes
San Antonio's older neighborhoods (Alamo Heights, Olmos Park, Monte Vista, Terrell Hills) parallel Central Austin's mix of older homes and full-frame work. Stone Oak, Shavano Park, and the newer Loop 1604 corridors are mostly post-2000 production with builder vinyl. Pricing mirrors Austin within roughly 5%.

Why JP Exteriors for Windows
Window installation is the most error-prone trade in residential remodeling. A perfect window installed poorly leaks air, water, and sound. An average window installed perfectly performs near its rated spec for its full life. We bring three differentiators:
- Authorized installer for every major brand. We aren't single-line dealers pushing one product. We bring real options to your free estimate.
- In-house installation crews. Every window is installed by a JP Exteriors employee, not a subcontracted day-laborer crew.
- Lifetime workmanship warranty. Manufacturer warranties cover the unit. Our warranty covers the installation. Both apply.

Frequently Asked Questions
How much does a full-home window replacement cost in Austin in 2026?
A full-home window replacement of 15 to 20 windows in Austin or San Antonio runs $20,000 to $35,000 on average in 2026 for mid-tier vinyl windows from brands like Pella Encompass or Simonton. Premium vinyl (Pella 250) runs $16,000 to $30,000 on smaller window counts. Fiberglass premium lines like Marvin Elevate and Pella Impervia run $23,000 to $42,000. Wood premium (Marvin Ultimate, Pella Reserve, Andersen A-Series) runs $32,000 to $70,000+.
How much does one replacement window cost installed?
Per-window pricing in Austin and San Antonio in 2026 typically runs $700 to $1,200 for mid-tier vinyl, $1,200 to $1,800 for premium fiberglass, and $1,800 to $3,500+ for premium wood. Full-home pricing usually comes in slightly under the per-unit math because mobilization is shared across the project.
What's the difference between vinyl, fiberglass, and wood windows?
Vinyl windows are the most affordable, lowest maintenance, and dominant in Austin and San Antonio replacement projects. Fiberglass windows resist expansion and contraction better in Texas heat, hold paint, and last longer, which makes them a premium worth paying on Hill Country custom homes. Wood windows are reserved for luxury and historic-style projects in Central Austin, Westlake, and Alamo Heights.
Does JP Exteriors install Pella, Andersen, and Marvin windows?
Yes. JP Exteriors is an authorized installer for Pella (Encompass through Reserve), Andersen (A100, A-Series, 400 Series), Marvin (Essentials, Elevate, Ultimate), and ProVia. We also install Simonton, MI 1650, Burris AC, and other Texas-popular vinyl lines.
How long does window installation take?
Most full-home window replacement projects (15 to 20 windows) in Austin and San Antonio are completed in two to three days. Manufacturing lead time on premium fiberglass, composite, and wood is 6 to 10 weeks. Vinyl is typically 3 to 5 weeks.
Will new windows really lower my energy bill?
Yes, measurably. Replacing original single-pane builder windows in a typical 2,500 sq ft Austin home with modern low-E double-pane vinyl drops the summer cooling bill 20 to 30% in our experience. Going to premium fiberglass or triple-pane composite increases that savings further. Payback periods on the energy difference alone are typically 8 to 12 years.
What's the difference between insert and full-frame window installation?
An insert (retrofit) install replaces the sash and glass unit only when the existing frame is sound. A full-frame install replaces the entire frame when it's compromised by rot, leak history, or termite damage. Full-frame installs cost 25 to 60% more per opening and are usually required on 1970s to 1990s Central Texas homes with original wood frames.
