Single & Double Hung Windows in San Antonio, TX
Single hung and double hung windows are the most common window styles in San Antonio homes, and for good reason. Both feature a classic vertical design with two sashes stacked one above the other. The difference comes down to movement: a single hung window lets you open the bottom sash only, while a double hung lets you tilt or slide both the top and bottom sashes independently. At Juniper Windows San Antonio, we handle Window Installation for both styles across San Antonio neighborhoods from Alamo Heights to Stone Oak, and we give you a written price before a single screw turns.
We carry single and double hung options from ECO Window Systems, Mr-Glass, and ViewLux, and our crews handle the full Window Installation in San Antonio process from tear-out to trim. If you’re weighing your options, call us at (903) 488-7019 and we’ll walk you through what makes sense for your house, your budget, and how your windows face the Texas sun.
What Single & Double Hung Windows Cost in San Antonio
For a standard vinyl double hung window in San Antonio, expect to pay between $400 and $900 per window installed, including tear-out, haul-away, and new trim. Single hung windows typically run $300 to $700 installed. The spread comes down to glass package, frame material, size, and whether your home’s existing opening needs reframing. Impact-rated double hungs in San Antonio neighborhoods that fall within higher wind zones can push to $1,100 to $1,600 per window, depending on the product line you choose.
Here’s what drives the number:
| Factor | Typical Range |
|---|---|
| Standard single hung (vinyl, builder-grade) | $300 – $500 installed |
| Standard double hung (vinyl, mid-grade) | $450 – $750 installed |
| Double hung with Low-E glass upgrade | $550 – $900 installed |
| Impact-rated double hung (PGT or CWS) | $1,100 – $1,600 installed |
| Full-frame replacement (rot repair, reframing) | Add $150 – $400 per window |
| Stucco or brick exterior trim work | Add $100 – $250 per window |
Those numbers aren’t pulled from a national database. They reflect what we’ve priced on recent jobs in San Antonio, and we give every homeowner a line-item written quote before work starts. No vague estimates. No “we’ll see when we get in there.” The price you sign is the price you pay, covered in writing. Call (903) 488-7019 and we’ll send a technician to measure and quote your specific windows for free.
When You Need Single & Double Hung Windows
Most San Antonio homeowners call us when one of these situations shows up. If any sound familiar, you’re probably due for replacement:
- You can feel air moving around closed windows. In older San Antonio homes, worn weatherstripping and warped sashes let conditioned air leak out. Your AC works harder, and your July electric bill shows it.
- The bottom sash won’t stay up. Single hung windows rely on a balance system inside the frame. When it fails, the sash slams shut. In double hungs, both sashes can develop this problem independently.
- You can hear traffic or neighbors through the glass. Single-pane windows do almost nothing for sound. Modern double hungs from ViewLux or ECO Window Systems can cut exterior noise enough to make a real difference.
- Frames are rotting, sticking, or painted shut. San Antonio’s humidity plus decades of sun exposure breaks down wood frames. Once rot sets in, a replacement window alone won’t fix the problem; you need full-frame replacement.
- Your utility bills climb every summer. Heat gain through old glass is the single biggest energy leak in most San Antonio homes. Upgrading to Low-E double hungs can make a measurable dent.
- You’re prepping to sell. Windows are one of the first things a home inspector flags in San Antonio. Buyers notice fogged glass, cracked panes, and windows that don’t open.
Single Hung vs. Double Hung: How to Decide
If both styles fit your opening, the choice usually comes down to three things: air flow, maintenance, and budget. Here’s the straightforward version.
Single hung windows cost less upfront. Only the bottom sash moves, which means fewer moving parts, simpler hardware, and a lower unit cost. If you’re replacing windows on a rental property, a flip, or a guest bedroom that rarely gets opened, single hungs are often the smart money move.
Double hung windows give you ventilation control. Opening the top sash lets warm air escape while cooler air comes in through the bottom. That natural convection matters in San Antonio shoulder seasons like March and October, when you want airflow without running the AC. Both sashes also tilt inward for cleaning, which matters on second-story windows where exterior cleaning is a hassle.
We install both, and we won’t upsell you to double hungs if single hungs do the job, whether you need Awning & Hopper Windows or standard hung styles. The right answer depends on your house, not our margin. We’ll tell you which style fits each room when we measure.
Our Single & Double Hung Windows Process
Replacing windows in San Antonio shouldn’t feel like a gamble. Here’s exactly how it works with Juniper Windows San Antonio:
- Call us or book online. A real person answers at (903) 488-7019, 24/7. No voicemail maze. We schedule a measurement visit at a time that works for you, and we show up when we say we will.
- We measure every opening and inspect the frames. This is where we check for rot, check the square of each opening, and identify whether you need pocket replacement or full-frame replacement. We also look at which side of the house takes the most sun, because west-facing windows in San Antonio need different glass than north-facing ones.
- You get a written price. Before any work is scheduled, you’ll have a line-item quote covering windows, labor, trim, haul-away, and any frame repair. The number is locked. If site conditions change the scope, we tell you and we re-quote in writing before proceeding.
- Installation day. Our background-checked, uniformed technicians arrive and get to work. Your windows come out, the new ones go in, insulated, sealed, trimmed, and cleaned. You’ll get before-and-after photos of every opening.
- Walkthrough and digital invoice. We walk the job with you, make sure every window opens, locks, and seals. Then you pay from a link. Every installation is covered by our 365-Day Done Right Promise: if it’s not right, we make it right for a full year, parts and labor, in writing.
San Antonio-Specific Factors That Affect Your Windows
Windows in San Antonio do a different job than windows in Dallas or Houston. Our climate punishes glass in specific ways, and the right product choices account for that.
First, heat. San Antonio gets more than 220 sunny days a year, and our summer highs regularly top 100°F. That means Low-E coatings and the right U-factor matter more here than almost anywhere else in Texas. A double hung window with a U-factor of 0.30 or lower will dramatically reduce heat gain compared to the single-pane windows in older San Antonio homes. Mr-Glass and ViewLux both offer Low-E double hungs rated for our climate zone.
Second, humidity. San Antonio’s average relative humidity sits around 70% in the mornings, and our springs bring weeks of damp. Cheaper vinyl frames expand and contract with humidity swings, which is why we steer homeowners toward mid-grade or better vinyl lines rather than the cheapest builder units. Frames that warp in our humidity will bind within a few years.
Third, hail and wind. San Antonio sits in a region that gets hailstorms and the occasional severe thunderstorm with straight-line winds. If your home is near open areas in neighborhoods like Stone Oak or The Dominion, impact-rated glass is worth considering. Impact-rated glass is built to resist wind-borne debris without shattering, and in a double hung it means the difference between a broken pane and small business as usual after a storm.
Glass Packages and What They Actually Do
Window glass is not one-size-fits-all. Here’s what we recommend for San Antonio homes, in plain terms:
- Low-E coating. A microscopically thin metal coating on the glass that reflects heat. In San Antonio, it’s the single best upgrade you can make. It blocks a significant portion of solar heat gain while still letting light through.
- Argon or krypton gas fill. Between double panes, this inert gas acts as insulation. It’s standard in most mid-grade double hungs and it’s why double-pane windows outperform single panes by a large margin.
- Impact-rated glass. Laminated glass with an interlayer that holds shards together if the pane breaks. Consider it if you’re in a wind-exposed area or simply want the extra protection. ECO Window Systems offers impact-rated double hungs that don’t require a full frame replacement to upgrade.
- Tinted or solar-control glass. An option for west-facing rooms that bake in the afternoon. Reduces glare and heat without making the room feel like a cave.
We’ll recommend the glass package that matches each side of your house. A living room with big west-facing panes needs different glass than a north-facing spare bedroom, and we price honestly about whether an upgrade is worth it.

FAQs – Single & Double Hung Windows
How much does it cost to replace single and double hung windows in San Antonio?
Single hung window replacement in San Antonio typically runs $300 to $700 per window installed, and double hung replacement typically runs $400 to $900 per window, with impact-rated options from PGT or CWS running $1,100 to $1,600. Your exact price depends on window size, frame condition, and glass package. Call (903) 488-7019 for a free written quote on your specific windows.
Are double hung windows worth the extra cost over single hung?
For most San Antonio homeowners, yes, double hung windows are worth the upgrade if you want top-and-bottom ventilation and tilt-in cleaning, especially on second-story windows. If you’re flipping a house or replacing windows you rarely open, single hungs deliver the energy savings and fit the budget. We’ll give you our honest take room by room when we measure.
Can you replace my San Antonio windows the same week?
Yes, we can usually schedule installation within one to two weeks of your written quote, often sooner depending on product availability. Our lead times for ECO Window Systems, Mr-Glass, and ViewLux windows are typically shorter than custom manufacturers because we stock the most common San Antonio sizes, including 3-Panel Sliding (3-Lite Roller) Windows. Call (903) 488-7019 and we’ll check current availability for your specific window sizes.
Does Juniper handle the permit for window replacement in San Antonio?
Yes, we handle permitting when it’s required. San Antonio code requires permits for window replacement when the opening size changes or structural work is involved. We’ve worked with San Antonio’s Development Services Department for years and we’ll pull every required permit, schedule inspections, and make sure your installation passes the first time.
What’s the difference between a pocket replacement and a full-frame replacement?
A pocket replacement fits a new window into your existing frame, which costs less and works well if your frames are solid. A full-frame replacement removes the entire old window and frame down to the studs, which costs more but is necessary when there’s rot, water damage, or you want to change the window size. We’ll inspect each opening and tell you honestly which approach your home needs.
Ready to Replace Your San Antonio Windows?
If you’re ready for a straight answer on cost, call us at (903) 488-7019 or reach out through our home page. We’ll measure your windows, give you a written price on the spot, and schedule your installation on your timeline. No pressure, no vague numbers, no surprises.
