AfterHow Much Does Windows & Doors Cost in San Antonio?
Window and door replacement in San Antonio typically runs $300 to $1,200 per window and $800 to $4,500 per door, depending on size, glass type, frame material, and installation complexity. Most San Antonio homeowners replacing a full house of windows spend between $8,000 and $22,000 for a complete project.

Windows and Doors Cost Breakdown (2026)
The table below reflects what homeowners in the San Antonio market – from Alamo Heights to Helotes, Stone Oak to the South Side – are actually paying in 2026. Labor is included in these ranges. Permit fees, where required by the City of San Antonio or Bexar County, are not included and typically add $75 to $200 per project.
| Product Type | Low End | High End | Most Common Range |
|---|---|---|---|
| Standard double-hung window (vinyl) | $300 | $650 | $380 – $520 |
| Double-hung window (fiberglass or wood-clad) | $550 | $1,200 | $650 – $950 |
| Casement or awning window | $400 | $1,100 | $500 – $800 |
| Picture / fixed window | $250 | $900 | $350 – $650 |
| Bay or bow window | $1,400 | $4,500 | $2,000 – $3,200 |
| Impact-rated window (PGT, CGI, ES Windows) | $700 | $2,000 | $900 – $1,400 |
| Sliding glass / patio door | $900 | $3,200 | $1,200 – $2,200 |
| French door (pair) | $1,800 | $5,500 | $2,400 – $3,800 |
| Entry door (fiberglass, pre-hung) | $800 | $3,500 | $1,100 – $2,200 |
| Steel entry door | $700 | $2,200 | $900 – $1,600 |
| Custom or fully custom window/door unit | $1,500 | $8,000+ | Quoted per opening |
A few things drive these numbers up or down. The frame opening itself matters first – a standard rough opening costs less to prep than an older San Antonio home where the lintel has shifted over decades of heat cycling. Low-E glass coatings, argon-fill between panes, and triple-pane construction all add to the unit cost but typically pay back in lower CPS Energy bills within five to eight years. On the door side, sidelites, transoms, and multi-point locking hardware add cost quickly. And on any project where the existing frame is rotted or the sill plate has moisture damage – something we see regularly in homes near Salado Creek and in older Olmos Park bungalows – structural prep adds labor before a single new unit goes in.
That is why a written, itemized quote matters. At TruePane, we quote manufacturer lines side by side on paper so you can see exactly what you are buying before you decide. No surprises on the bill.

What Affects Windows and Doors Pricing in San Antonio
- San Antonio’s heat load and UV exposure. The city averages more than 220 sunny days a year and summer temperatures regularly exceed 100 degrees in neighborhoods like Converse and Universal City. Low-E coatings and solar heat gain coefficient (SHGC) ratings matter more here than they do in cooler markets – and the right glass specification costs more upfront but protects interior finishes and reduces cooling loads meaningfully.
- Frame material choice. Vinyl is the most common choice in San Antonio’s entry and mid-range market and holds up well to UV. Fiberglass costs roughly 20 to 40 percent more but expands and contracts less in extreme heat, which reduces seal failure over time. Wood-clad frames from lines like Andersen or Marvin add warmth and character to older historic homes in King William or Mahncke Park, but they carry a premium and require periodic maintenance.
- Glass package and performance ratings. Double-pane is standard; triple-pane adds cost but is worth considering if a room faces west and bakes all afternoon. Impact-rated laminated glass – required or strongly recommended in some flood-zone and high-wind-corridor parts of Bexar County – runs 30 to 60 percent more than standard insulated glass but eliminates the need for separate storm shutters.
- Opening condition and structural prep. Homes built before 1985 in San Antonio often have original aluminum single-pane frames set in openings that are no longer perfectly square. Resquaring, shimming, and flashing those openings adds labor. If there is wood rot in the sill or head casing, that has to be addressed before the new unit goes in – skipping it is how warranties get voided and how water intrusion problems start.
- Number of units and project scope. A full-house replacement of 15 to 20 windows is almost always quoted at a lower per-unit cost than a single-window job. The crew mobilization, permit pull, and disposal cost are spread across more units. If you are on the fence about one or two marginal windows, replacing them alongside the others usually costs less than a return trip.
- Permit requirements. The City of San Antonio Building Inspections office requires permits for full window replacements in some circumstances, particularly when structural modifications are involved or when the home is in a historic overlay district. Bexar County has its own requirements for unincorporated areas. TruePane handles the permit process as part of the job – it is not an afterthought we hand back to the homeowner.

How to Save on Windows and Doors in San Antonio
There is a version of savings that costs more in the long run: the low bid from a crew that sets a window out of true, skips the flashing, and is unreachable six months later when the seal fogs. We have been correcting that work in San Antonio homes since 2008. The advice below is about genuine savings.
Bundle the project when you can
If you have been watching three windows for a while and know two doors are coming, do it in one visit. Per-unit labor drops when the crew is already on-site. Permitting is often one fee rather than several. And you schedule the disruption once instead of three times.
Use CPS Energy rebates
CPS Energy offers rebates on qualifying energy-efficient windows in San Antonio. The amounts change year to year, but in 2025 and into 2026, qualifying ENERGY STAR windows have been eligible for rebates in the $30 to $75 per window range. Ask for documentation of the U-factor and SHGC rating when you get your quote – you will need those numbers to file the rebate.
Ask about the senior and veteran discount
TruePane offers a permanent 5% discount for seniors and veterans on every job. It is not a limited-time promotion and it does not require any special paperwork beyond confirming eligibility. If that applies to you, mention it when you call.
Take the Free Written Repair Estimates
If a full replacement is not in the budget right now but a foggy seal, broken hardware, or failed weatherstripping needs attention, TruePane’s standing a free written repair estimate applies. Sometimes the right move is a well-done repair, not a replacement – and a square deal on the repair is better than cutting corners to get to a lower replacement bid.
Schedule in the slower season
Spring and fall are the busiest seasons for window and door work in San Antonio. January and February are typically slower, and some manufacturers offer seasonal promotions on stock units during that window. Lead times on custom and special-order units are also shorter when production is not backlogged.
Get a free, written estimate before you commit to anything
It costs nothing to know what the work actually involves. Call (888) 635-0804 and we will schedule an in-home estimate at a time that works for you. You will get line-item pricing on paper, manufacturer lines quoted side by side, and no pressure to decide on the spot. That is the baseline for making a genuinely informed decision.

FAQs – Windows and Doors Cost in San Antonio
How much does a single window replacement cost in San Antonio?
A single window replacement in San Antonio typically costs $350 to $900 for a standard double-hung or casement window, installed. That range covers a mid-grade vinyl or fiberglass unit with a double-pane, Low-E glass package. Larger picture windows, bay units, or impact-rated glass will run higher. Custom sizes or historic profiles – common in King William and the Tobin Hill area – are quoted per opening. Call (888) 635-0804 for a free in-home estimate with exact numbers for your specific window.
Is it cheaper to repair or replace a window in San Antonio?
Repair is cheaper in the short term: a fogged seal replacement runs $150 to $350, hardware repairs typically $75 to $200, and weatherstripping often under $100. Replacement makes more financial sense when the frame is rotted, the glass is original single-pane, or the window repeatedly fails after repair. A good rule of thumb: if the repair cost exceeds 40 percent of the replacement cost and the unit is more than 20 years old, replacement is usually the better investment. We will tell you honestly which one applies to your situation.
How much does entry door replacement cost in San Antonio?
A standard pre-hung fiberglass entry door in San Antonio runs $1,100 to $2,200 installed. Steel doors start slightly lower, around $900 to $1,600 installed. Wood doors and custom units can reach $4,000 or more depending on the panel design, glass lite configuration, and hardware. San Antonio’s heat and UV exposure make fiberglass a strong long-term choice – it does not warp, fade, or dent the way wood and steel can after years of south-facing sun exposure. Call (888) 635-0804 for a free estimate on your specific door.
How long does window and door installation take in San Antonio?
Most single-window and single-door jobs are completed in two to four hours. A full-house window replacement of 15 to 20 units typically takes one to two days, depending on access, opening condition, and whether structural prep is needed. Most projects are done in a single visit – that is the standard, not an exception. If a return trip is needed, we schedule it promptly and do not leave you with an open opening. Custom and special-order units have lead times of three to six weeks before installation day.
Do I need a permit to replace windows or doors in San Antonio?
It depends on the scope of work and where you live. The City of San Antonio requires permits for structural modifications, changes to opening size, and work in designated historic overlay districts – including parts of Monte Vista, King William, and Beacon Hill. Straight same-size replacement in a standard residential zone often does not require a permit, but the rules have specific conditions. TruePane determines permit requirements as part of the quoting process and handles the filing when a permit is needed. You will not be handed that task at the last minute.
What window brands does TruePane install in San Antonio?
TruePane is an authorized installer for more than a dozen manufacturer lines including, PGT, CGI, and ES Windows. Being an authorized installer means both warranty layers – the manufacturer’s product warranty and the installation warranty – are registered in writing before the truck leaves the driveway. That is The Keystone Standard. A non-authorized installer often cannot register the full manufacturer warranty, which means you may have coverage on paper that does not hold up when you need it.

What Our Customers Say
"A casement crank had stripped and the sash was swollen shut. The technician, Ray, fixed the crank on the spot and only then talked about replacement for the three windows that were genuinely done. That is why the whole street uses them now."
- Eleanor G."French doors to the patio, custom size because this house was built in 1961 and nothing is standard. Measured twice, three weeks to fabricate like they warned, and the install day they laid runners over my floors without being asked."
- Marie S."Our bay window had rotted at the sill and two other outfits wanted to talk us into a flat picture window instead. TruePane rebuilt the opening and matched the original look. Neighbors have knocked on the door about it."
- Gene A.
