AfterHow Much Does Custom Window & Door Order Cost in San Antonio?
Custom window and door orders in San Antonio typically run between $4,500 and $25,000 per project in 2026, depending on how many openings you’re replacing, the materials you choose, and whether the job requires structural work. Most homeowners across San Antonio spend somewhere around $8,000 to $15,000 for a complete upgrade of window and door openings on an average single-story home. If you’re looking at impact-rated windows, a full-home project in areas like Alamo Heights, Stone Oak, or Helotes can push past $20,000, while a single custom front door with sidelights often lands between $3,000 and $8,000.

These ranges are current for the San Antonio market in 2026. Your specific price will land somewhere in here based on what’s driving the job, which we’ll get into below.
What Drives the Price Up or Down
Window count is the biggest lever. A 3-bedroom, 2-bath home in San Antonio typically has 10 to 14 windows. At the low end with vinyl frames and standard sizing, you’re looking at $450 to $600 per window. Step up to fiberglass or wood-clad frames and that per-window number climbs to $800 to $1,500. Custom sizing always adds cost because the manufacturer cuts each unit specifically for your openings rather than pulling from stock inventory. Homes built in the 1970s and 1980s, common in areas like Woodlawn Lake and Highland Park, often have non-standard rough openings that require custom orders simply because stock units won’t fit without significant frame work.
Material choice matters more in San Antonio than in many other markets. Our intense summer heat and UV exposure means cheap vinyl frames can warp or fade within a decade on west-facing walls. We often recommend upgrading to reinforced vinyl or fiberglass on the west elevation of a home, especially in areas like Cibolo or Schertz where afternoon sun exposure is brutal in July and August. That upgrade typically adds 15 to 30 percent to the per-window cost.
Energy-efficiency ratings also move the needle. A basic single-pane window is uncommon now and honestly a poor choice in San Antonio, where summer cooling costs dominate utility bills. Double-pane with Low-E coating and argon gas fill typically adds $100 to $250 per window over bare double-pane. Triple-pane adds another $300 to $600 per window. Most homeowners in San Antonio find double-pane with Low-E is the right balance: it handles the heat without paying triple-pane premiums that rarely pay back in our climate.
Doors follow similar logic. A basic steel entry door with no glass and minimal detailing runs $1,800 to $2,500 installed. Add glass panels, decorative iron work, sidelights, or a transom and you’re quickly at $4,000 to $8,000. Custom wood doors, especially mesquite or other dense hardwoods, can exceed $10,000 for the door alone before installation.
Labor costs in San Antonio are moderate compared to Austin or Dallas, which works in your favor. Typical installation labor for a single window runs $150 to $400 depending on accessibility. Second-story windows cost more because of ladder or scaffold work. Interior window replacement in older homes with wood siding, like many houses in Monticello Park or King William, often requires careful exterior trim work to prevent rot, which adds $100 to $300 per window.
What Affects Custom Window & Door Order Pricing in San Antonio
Here are the factors that most affect what you’ll pay for custom windows and doors in San Antonio. None of these are abstract: each one shows up as a specific line item on written estimates we prepare for homeowners in the area.
- Window count and sizing. More openings means more units and more labor. Non-standard sizes require custom manufacturing that costs $150 to $400 more per unit than standard stock dimensions. Older homes in San Antonio, especially those built before 1980 in areas like Jefferson or Beacon Hill, frequently have odd rough-opening sizes that force custom windows.
- Frame material. Vinyl is the entry point, fiberglass and wood-clad are the premium options. In San Antonio’s heat, reinforced vinyl or fiberglass for west-facing and south-facing windows prevents warping and seal failures that we see frequently in homes around the Medical Center and Shavano Park. Plan on paying $300 to $800 more per window for fiberglass over basic vinyl.
- Energy-efficiency package. Low-E coating, argon fill, and warm-edge spacers are standard recommendations for San Antonio’s climate. This is not an upsell: a west-facing wall in a Terrell Hills home can hit 140 degrees on the interior glass surface in August without proper Low-E. Expect $100 to $250 per window for full energy packages over bare double-pane.
- Impact-rating requirements. If you want hurricane-rated or impact-resistant windows, the cost jumps significantly. Impact-rated installations run $800 to $2,500 per window. These aren’t required by building code for most of San Antonio, but many homeowners in areas like Fair Oaks Ranch or Boerne choose them for insurance discounts and storm protection.
- Structural condition of existing openings. If your current window or door frames have water damage, rot, or termite damage, the repair work adds cost before the new unit goes in. We regularly find rotted sills on older homes in Olmos Park and Alamo Heights because of our heavy spring and fall rain seasons. Rot repair typically adds $400 to $1,500 per opening.
- Stucco or masonry exterior work. Many San Antonio homes built from the 1990s onward have stucco exteriors. Replacing windows in stucco requires careful cutting, flashing, and patching that adds $200 to $500 per window over wood or vinyl siding installations. Homes in areas like the Vineyard or Alamo Ranch frequently hit this upcharge.
- Permit requirements. The City of San Antonio requires permits for window and door replacements when the opening size changes or structural modifications are involved. Permit fees are typically $100 to $400 depending on scope, and that cost is included in any written estimate Mason Remodeling provides. We handle the permit paperwork so you don’t have to deal with the Development Services Department.
How to Save on Custom Window & Door Order in San Antonio
There are smart ways to reduce your custom window and door costs without compromising quality or ending up with units that fail in San Antonio’s heat. Here’s what we tell homeowners who want to get the best value.
Replace windows in phases. You don’t have to do every window at once. Start with the west-facing and south-facing elevations: those are the windows that take the worst heat in San Antonio and typically fail first. Once those are done, budget for the remaining elevations in a later phase. You’ll pay slightly more per window on smaller orders due to setup costs, but it spreads the project across months or years.
Choose reinforced vinyl over wood or fiberglass. Modern reinforced vinyl windows from manufacturers like Milgard and Simonton handle San Antonio’s climate well without the premium cost of wood-clad or fiberglass. You lose some aesthetic flexibility, but if budget is the priority, this is where you save. A north-facing window doesn’t need the same thermal rating as a west-facing one either, so you can mix and match within the same home.
Keep the existing frame when it’s still solid. If the window opening is square, level, and free of rot, we can sometimes install a replacement unit into the existing frame. This cuts labor and material costs for trim and flashing work. We’ll tell you honestly if your existing frames can support this: in many older San Antonio homes they can’t, but in newer construction they often can.
Bundle windows and doors in a single order. If you’re replacing an entry door and several windows, do it as one project. The manufacturer’s setup charges and our mobilization costs get spread across more openings, and you’ll see a lower per-unit price on both.
Check manufacturer rebates and utility incentives. CPS Energy in San Antonio periodically offers rebates for energy-efficient window upgrades. These programs change, but they’re worth checking before you finalize your order. Mason Remodeling will help you identify what’s available at no charge.
The most straightforward way to get an accurate number is to call (254) 269-5071. Mason Remodeling Co San Antonio provides free estimates with a written price before any work begins. You’ll know exactly what you’re paying before a single tool is unpacked.
Custom Windows and Doors vs. Stock Options: What You’re Actually Paying For
Custom means the window or door is manufactured to your specific measurements and specifications rather than pulled from warehouse inventory. It’s not just about aesthetics: custom orders allow exact frame material, glass package, color, hardware finish, and grid pattern. They also allow true sizing, which matters in many San Antonio homes where rough openings were never standardized.
The price difference between stock and custom is real but smaller than most people expect. A stock vinyl window runs $250 to $500 per unit at big-box stores. Custom vinyl windows from a manufacturer like Andersen or Pella run $450 to $1,200 per unit for the same nominal size. That premium buys you exact fit, better glass packages, stronger frames, and a manufacturer warranty that’s enforced through authorized installers like Mason Remodeling. With stock windows, an improper fit gets shimmed and caulked, and five years later you have air leaks and condensation issues.
For doors, the difference is more dramatic. Stock doors from home centers run $300 to $900. Custom entry doors from a fabricator run $1,800 to $8,000 installed. The custom door includes a proper pre-hung frame, correct weatherstripping, real wood or fiberglass construction rather than hollow-core, and hardware that holds up. In San Antonio’s humidity swings and heat, cheap entry doors warp within three to five years. We replace warped big-box doors regularly in neighborhoods across San Antonio, especially on west-facing entries.
You can explore our Custom Window & Door Order in San Antonio services to see exactly what a full project involves. And if you’re also considering broader improvements, a custom window project often pairs well with other work we handle, from a full home remodel to a single-room update.
Permits and Code Requirements for Window and Door Work in San Antonio
The City of San Antonio requires building permits for window and door replacement when the opening size changes, when structural headers are modified, or when the work involves exterior wall penetrations in certain zones. If you’re swapping a window for a window of the same size, a permit is often not required. If you’re enlarging an opening, adding a door where a window existed, or changing a wall’s structural configuration, a permit is mandatory.
Historic districts add another layer. Homes in King William, Monticello Park, and parts of Lavaca fall under Historic and Design Review Commission oversight. Window and door changes on the street-facing elevations of these properties require design approval, which can add weeks to your timeline and $200 to $500 in application fees. If you live in a historic district, plan for this before ordering custom units. Mason Remodeling handles the paperwork for you, including HDRC applications, so you’re not navigating city bureaucracy alone.
Energy code compliance matters too. San Antonio enforces the 2021 International Energy Conservation Code with local amendments. New windows must meet minimum U-factor and Solar Heat Gain Coefficient (SHGC) ratings appropriate for our climate zone. This is not a hidden catch: any competent window installer in San Antonio specs products that exceed these minimums. Our standard recommendation of double-pane with Low-E and argon meets or exceeds code in every application.
How Mason Remodeling Handles Custom Window and Door Orders
Here’s the process we follow on every custom window and door order in San Antonio, and it’s worth knowing because it protects you at each stage. We’ve been doing this since 2004 as part of the Threshold Group family of home-service companies, and the process hasn’t changed in its essentials.
First, you talk to a live person. When you call (254) 269-5071, a real human answers, 24 hours a day, 7 days a week. No call trees, no voicemail loops. We schedule a consultation at a time that works for you.
Second, we measure everything. Our technicians come to your home in San Antonio, measure every window and door opening precisely, and document the condition of existing frames, trim, and structural surrounds. We check for rot, termite damage, improper flashing, and other issues that affect installation quality. These findings go into your written estimate as line items, not as surprises later.
Third, you receive a written price. Before any work begins, you get a detailed written estimate. This is The Threshold Standard, and it’s not optional: every Mason Remodeling project includes a written price before a single tool is unpacked. If the number changes for any reason during the project, we discuss it with you and get written approval before moving forward. No surprise invoices, no verbal estimates that grow on the final bill.
Fourth, you know who is coming. Before the installation crew arrives, you receive the name and photo of every technician scheduled for your job. Each crew member is background-checked, identity-verified, arrives in a clean marked uniform, and shows a photo ID badge at your door. This matters for any homeowner, and especially for people who are often home alone, parents with young children, or older adults. You never open your door to a stranger on our jobs.
Fifth, the work is guaranteed in writing. Every completed project comes with a written guarantee stating exactly what’s covered, what’s excluded, and for how long. For remodeling work, our 365-Day Done Right Promise applies: if the work isn’t right within a year of completion, we make it right at no cost to you. For window and door installations, the manufacturer warranties on the units are passed through to you in writing, and our installation workmanship is covered under the same written guarantee terms.
Sixth, if something fails, we return free. If a repair or installation fails, you get a free second visit. No charge, no dispute process, no conditions. This is part of how we’ve operated since Isaac Pruett established our standards in 2004.
We work with specification-grade window and door manufacturers, which means you get access to vetted, professional-grade products rather than whatever is cheapest this week at a big-box store. That matters in San Antonio’s climate, where window quality determines your cooling costs for decades.

How long does a custom window and door order take in San Antonio?

Do I need a permit for window and door replacement in San Antonio?
Permits are required in San Antonio when you change opening sizes, modify structural headers, or add new openings. Like-for-like replacements typically don’t require a permit.

Historic district homes require additional design review, which we also manage for you.
Can you install custom windows and doors the same day?
