Kirby’s housing stock isn’t like the newer subdivisions going up around San Antonio. These are compact single-story homes from the 1950s through the 1970s, built when single-pane aluminum was standard and energy codes didn’t exist. We’ve worked on hundreds of them. When our crews open up an original window opening in Kirby, we expect what’s behind it: undersized headers, rotted jambs, missing flashing, and the occasional permit correction the city requires once the rough opening is exposed. Our process accounts for that from the first inspection, so your quote doesn’t move on you mid-project.

Why Juniper Windows San Antonio Is Kirby’s Preferred Window Installation Company

We’re the Window Installation team Kirby homeowners call when they want a real price, not a hand-wave estimate. Sean Mackey leads our crew, and the standard he sets is simple: inspect the opening, document what we find, write the price, and get your approval on paper before a single screw turns. That matters in Kirby because the homes here were built before modern flashing and header requirements, and a sloppy installer will hide what they find because they don’t want the quote to move. We’d rather show you the rotted jamb and fix it right.

Our Kirby customers consistently tell us the same thing: the written price held, the crew showed up when they said they would, and the before-and-after photos meant no surprises. We roll a uniformed, background-checked crew to every Kirby job, and you’ll get a live arrival time you can track from your phone. That’s the Relay Visibility Guarantee, and it’s how every job runs. Founded in 2001 as part of the Relay Home Co. family, Juniper has more than two decades of installations behind the brand, and every single one is covered by the 365-Day Done Right Promise: if the work isn’t right, parts and labor are covered in writing for a full year.

Bay Window Installation in Kirby

Bay window installation in Kirby typically costs $2,800 – $6,500 for a full three-panel bay with seat and roof, and most of the older ranch homes we work on have never had one framed correctly to begin with. A bay window in Kirby isn’t a straightforward swap; it’s a structural addition that changes the wall’s load path, and on these shallow 2×4 frames from the 1960s, we often have to install a beefier header than code required when the house was built. You’ll want this done by a crew that understands Kirby’s specific combination of brick veneer, hardboard siding, and aging framing.

Framing and Header Corrections

When we pull an old double-hung or a jalousie unit from a Kirby ranch to make room for a bay, we open the wall and check exactly what’s carrying the load. Undersized headers are common in 1950s – 70s construction, and once the rough opening is exposed, Kirby’s current residential code often requires an upgrade. We write that correction into your contract as an allowance, with photo documentation, so nothing gets billed without your written approval.

Seat, Roof, and Moisture Control

A bay window juts out from the house, which means it needs its own small roof and a properly flashed seat. On Kirby homes with hardboard siding, trapped moisture behind window flanges is a frequent problem we uncover during bay retrofits. We replace rotted sheathing where needed and install the bay with continuous flashing so the new unit sheds water instead of feeding it into the wall.

Window Contractor in Kirby

A window contractor in Kirby should know exactly what a 1963 brick-veneer ranch off Ackerman Road looks like inside the wall before they quote you a number. Juniper Windows San Antonio has been running crews into Kirby long enough to know what waits behind original aluminum frames: humidity-weakened jambs, missing flashing, and shallow wall depths that complicate any upgrade to an insulated unit. A full-frame replacement in Kirby runs $850 – $1,850 per window, while an insert into a sound existing frame usually falls between $450 and $900. We’ll confirm which route applies to your home during the estimate.

Photo-Documented Change Orders

On that Ackerman Road job, our crew pulled an original aluminum double-hung and found the jamb rotted through from decades of humidity weeping through failed caulk. We reframed the rough opening with pressure-treated lumber, installed a PGT vinyl low-E double-hung with a Miami-Dade NOA rating, and wrote the repair into the contract only after the homeowner approved our photo-documented change order. That’s the only way we work in Kirby: you see what we see, and you approve every added line item before we touch it.

Permit and Code Compliance

Kirby’s current residential code applies to structural changes around window openings, and a full-frame replacement that alters the opening triggers a permit. We pull it. We also schedule the inspection and make sure the work passes before we call the job done. An insert replacement into an existing, unmodified opening typically doesn’t require a permit, but we’ll tell you up front which category your project falls into.

Trusted Brands We Service in Kirby

We stock and install ECO Window Systems, Mr-Glass, and ViewLux products for Kirby homeowners, which means you’re not waiting on a special order from a distributor two states away when you need a specific sash or hardware match. PGT and Therma-Tru round out the lines we carry, and our Kirby customers most often choose ECO for budget-conscious retrofits and ViewLux for tighter sightlines on mid-century ranch styles. If you have a specific brand in mind, call (903) 488-7019 and we’ll confirm availability for your rough opening size.

Common Window Installation Problems We See in Kirby Homes

• Original jalousie louvers on porch enclosures: These look charming until removal. The aluminum tracks are frequently corroded from decades of humidity, the glass is cracked, and what’s left behind is an open wall condition that doesn’t meet current code. We replace them with insulated vinyl units sized for the shallow wall depth.
• Rotted jambs from failed caulk: South Texas heat and Kirby’s high humidity work on caulk until it fails, then moisture weeps into the jamb for years. By the time the window is replaced, the wood often needs reframing, not just a new unit.
• Shallow 2×4 wall cavities: Kirby’s 1950s – 70s ranches were framed when windows were thin and flanges were an afterthought. A modern insulated unit is deeper, which means flashing and head heights sometimes don’t meet Kirby’s current code without a correction the homeowner never expected.
• Hardboard siding trapping moisture behind flanges: Hardboard absorbs water, and when it sits against a window flange, rot spreads behind the siding where you can’t see it. A simple insert installation can turn into a sheathing and jamb replacement once we expose the flange. We carry a written allowance for this in our Kirby contracts.
