Fast, Reliable Window Installation Across Alamo Heights
Window installation in Alamo Heights runs $600 – $2,800 per opening for most jobs, with full-home projects on 1920s – 1960s homes typically landing between $14,000 and $38,000 depending on glass packages and structural work. If you’re in Alamo Heights, you’re dealing with a housing stock most window crews rarely see: thick masonry walls, deep sills, and original windows protected by design review rules. We schedule free estimates across Alamo Heights within a few days, and our crew knows these homes well enough to flag code triggers before they become surprise invoices. Call us at (903) 488-7019 to get a written price.
Why Juniper Windows San Antonio Is Alamo Heights’s Preferred Window Installation Company
We’re the Window Installation team that Alamo Heights homeowners call when they need a crew that understands the difference between a 1930s Spanish Eclectic and a 1960s Ranch. Every job in Alamo Heights starts with an inspection that looks at more than the sash. We check the framing behind the stucco, the condition of the jamb pockets, and whether the existing header will pass design pressure calcs once heavier glass goes in. Sean Mackey leads our crew, and he’s the person who walks the site and writes your quote. No salesperson padding numbers. Just a straight read on what the house actually needs.
What separates us is the paper trail. Every Alamo Heights project gets a written price before anything starts, and that price is backed by the 365-Day Done Right Promise: fixes covered for a full year, parts and labor, in writing. Homeowners here are busy people who book everything on their phone. They get a live arrival time, photo updates during the install, and a digital invoice they can pay from a link. Calls are answered by a live person 24/7, so if a question comes up at 9 p.m. about your garden window rough opening, you’re not leaving a voicemail.
Double Hung Windows in Alamo Heights
Double Hung Windows in Alamo Heights are one of the most common installs we do, largely because so many 1920s – 1950s homes here were originally built with wood double-hungs that have since rotted, stuck, or lost their weatherstripping. A standard double hung replacement in Alamo Heights runs $700 – $1,900 per window for a mid-grade vinyl or thermally broken aluminum unit, and $1,500 – $2,800 if you’re matching a historic muntin profile with custom millwork.
Historic Sash Matching
When design review requires the new sash to match the original sightlines, we order units with the correct muntin width and profile. That’s not something a stock window accomplishes, and it’s why our quotes here sometimes carry a millwork line item neighbors in San Antonio never see. The result is a double hung that operates like new but reads original from the street.
Framing Repairs Behind the Sash
On pre-1960 Alamo Heights homes, we regularly find the original header undersized for anything heavier than single-strength glass. Once we pull the old sash, if the header fails design pressure calcs, that triggers a permit-mandated structural upgrade. We write that allowance into the contract before we start, so the price doesn’t jump mid-job.
Vinyl Windows in Alamo Heights
Vinyl Windows in Alamo Heights are the workhorse choice for homeowners who want energy efficiency without fighting the historic review process on a non-contributing structure. A standard vinyl window install in Alamo Heights runs $600 – $1,400 per opening, with higher-end lines like ViewLux pushing toward $1,800 for larger triple-pane configurations.
Efficiency Without the Historic Premium
For 1960s Ranch homes and later builds, vinyl is often the smart money. We install ECO Window Systems and ViewLux vinyl units with low-E glass and argon fills, and we’ll walk you through U-factor numbers so you know exactly what you’re paying for. The hot, humid Alamo Heights summers make a real difference here: a well-sealed vinyl unit cuts solar gain noticeably compared to a 60-year-old single-pane original.
Deep Recess Install Detail
Alamo Heights masonry walls create deep window recesses that box-store pocket replacements don’t handle well. We install with custom jamb extensions and pan flashing rather than relying on the factory trim kit. Without that step, water finds the sill within a storm season. Our flashing detail is part of every vinyl install here, and it’s covered under the 365-Day Done Right Promise.
Trusted Brands We Service in Alamo Heights
We work with eight product lines, and for Alamo Heights we lean on ECO Window Systems, Mr-Glass, and Therma-Tru most often. ECO gives us the thermally broken aluminum frames that hold up in thick masonry openings. Mr-Glass covers the custom reglazing and historic glass work. Therma-Tru handles the entry doors many homeowners replace alongside windows on these older homes. We keep common parts and weatherstripping local, so a warranty repair or follow-up doesn’t wait on a distributor three states over.
Common Window Installation Problems We See in Alamo Heights Homes
- Failed waterproofing behind original steel casements. Stucco-over-hollow-clay-tile construction hides decades of water intrusion. When we pull the sash on a 1930s Spanish Eclectic, the jamb pockets are frequently rotted and the surrounding mortar is crumbling. Code requires fixing that before we reinstall anything.
- Warped 1940s steel casements that jam shut. In the Olmos Park Terrace area specifically, original single-strength steel casements bow in the summer heat until the sash won’t move. Owners call us because the window is stuck open or stuck shut, and the fix usually means a full replacement with a thermally broken unit that matches the original sightline.
- Undersized framing when heavier glass goes in. Original wood double-hungs in pre-1960 homes often sit in rough openings with undersized headers. The moment we spec an impact-rated or even a standard insulated glass unit, the header fails the design pressure calculation and the permit triggers a structural supplement.
- Deep masonry recesses that trap water. Thick stucco walls create recessed window pockets that standard vinyl pocket replacements don’t flash correctly. A box-store install in a hollow-clay-tile wall leaks at the sill within one storm season. Our pan flashing and jamb extension detail is specific to this construction type.
Pricing for Window Installation in Alamo Heights, TX
Here’s straight talk. A single window in Alamo Heights runs $600 – $2,800 installed, and what moves the number is the glass package, the frame material, and whether the existing opening needs structural work. Double hungs cluster around $700 – $1,900. Vinyl units land $600 – $1,400. Casements in masonry walls run $900 – $2,200 because of the custom flashing. Full-home jobs on these older homes typically run $14,000 – $38,000. The permit itself is a fixed cost we pass through, but the upgrades it triggers are where estimates diverge. We write allowances for framing and waterproofing into the contract, and anything outside allowance gets priced and approved in writing before we touch it.

FAQs About Window Installation in Alamo Heights
Because the inspection found what was hiding behind the stucco, and that work is now required. On Alamo Heights homes built before 1960, we often discover rotted jamb pockets, crumbling mortar, or an undersized header once the city inspector reviews the rough opening. We write allowances into the contract for exactly this, so the final number moves within a range you already saw. Call (903) 488-7019 and ask us to walk you through what the permit triggers on your house before you sign.
Yes, if your home falls under design review, the replacement sash or casement must match the original sightline and muntin profile. That doesn’t mean original single-pane glass. It means a new thermally broken unit with custom millwork that looks correct from the street. We handle that routinely. Call (903) 488-7019 for a quote that includes the millwork line item.
We don’t try to bend them back. A warped steel casement from the 1940s has lost its structural integrity, and reglazing won’t fix a jamb that jams shut. We replace with a thermally broken ES Windows casement that matches the original 1″ muntin profile, and we flash the deep masonry recess so it doesn’t leak. This is one of the most common jobs we do in Olmos Park Terrace.
Not automatically. A window permit triggers structural review of the rough opening, not an electrical upgrade. Impact glass is not a blanket requirement in Alamo Heights, but if you’re in a wind-borne debris zone or your insurer requires it, we’ll spec an impact-rated unit. The structural upgrade, if any, is what we calculate before quoting. Call (903) 488-7019 for the exact scope on your address.
Yes, with custom jamb extensions and proper pan flashing, the new double hung can sit in the same deep recess and keep the interior sill depth. That’s the detail work we do on Alamo Heights masonry walls. A pocket replacement from a box store won’t get that right. We’ll show you the flashing detail in your written quote. Call (903) 488-7019 to schedule the free estimate.
