Trusted Window Installation for Austin Homeowners
Window installation in Austin runs anywhere from $450 for a basic single vinyl unit up to $4,800 or more for a full bay window with structural work, and most homeowners pay between $800 and $1,900 per opening when you account for labor, flashing, insulation, and disposal. That range reflects what we actually see across neighborhoods like Cherrywood, Crestview, and Circle C Ranch, not a national average pulled from a lead-gen site. Westlight Windows Austin has been installing windows since 2009, and every job carries the Kingswell Guarantee: a written price before work starts, a committed arrival window, a clean job site, and a written guarantee you can hold us to. If you’re looking for a window installer in Austin who will actually answer the phone and stand behind the work, call Owen and the team at (254) 322-3468.
We know why you’re reading this. You’ve either got a window that’s failing, a room that won’t hold temperature, or you’ve already had a contractor quote you one number and then hand you a different invoice at the door. That does not happen with us. The Kingswell Way is simple: say the price before the work, show up in the window we gave, leave the place cleaner than we found it, put the guarantee in writing, and come back if it fails. No exceptions, no fine print gymnastics.
Casement Windows
Casement windows are hinged on one side and crank outward, sealing tightly against the frame when closed, which makes them one of the most energy-efficient operable window styles you can put in an Austin home. They work exceptionally well in kitchens and bathrooms where you want a full, unobstructed opening and easy one-hand operation over a counter or sink. Westlight Windows Austin installs casement windows from PGT, CGI, ES Windows, and other lines we stock, with most casement replacements in Austin running $700 to $2,200 per unit installed depending on size, frame material, and glass package. The price you get is the price you pay, in writing, before any work begins.
Crank Operation and Hardware Upgrades
The crank mechanism on a casement window is the part that fails first, especially in humid climates where the gears corrode. We inspect the full operator assembly, hinge points, and locking hardware at quote so you know upfront whether a repair or a full replacement makes sense. Our crews replace worn hardware with manufacturer-spec parts, never generic knockoffs, because a casement window that doesn’t seal is just a picture window with extra steps.
Best Rooms for Casement Windows
In Austin ranch homes and new builds across Mueller and Easton Park, casement windows show up most often in kitchens, above garden beds, and in tight bathroom spaces. They catch side breezes well, which matters in a city where May through September tests every window in the house. If you’re replacing a double-hung in a kitchen with a casement, you’ll gain seal integrity and often a few extra inches of visible glass.
Double Hung Windows
Double hung windows have two sashes that slide vertically, top and bottom, giving you ventilation from either end and easy cleaning because both sashes tilt inward. They’re the most common window style in older Austin homes, from the craftsman bungalows in Hyde Park to the 80s builds in Brushy Creek, and replacing them is usually a straightforward one-to-one swap. Most double hung window installations in Austin run $550 to $1,850 per opening installed, with the final number tied to glass package, grid pattern, and whether the opening needs any reframing. Owen Satterfield and his crew have installed thousands of double hungs across the Austin metro since 2009, and every quote is a written, fixed number.
Tilt-In Sash and Solar Heat Gain
In Austin’s climate, the glass package on a double hung matters more than most people realize. A standard clear double-pane still lets an enormous amount of solar heat into the room, which is why we default to recommending low-e glass (a thin coating that reflects heat back into the room in winter and out in summer) on every south- and west-facing window we quote. The tilt-in sashes also mean you can clean both sides from inside, which any two-story homeowner in Anderson Mill will tell you is the difference between clean windows and never clean windows.
Original Window Replacement in Historic Districts
If you own a pre-1960 home in a historic district like Old West Austin or the Bremond Block, Austin’s preservation rules can affect what you’re allowed to install. We’ve worked through those reviews before and can help you navigate what’s required, including matching sightlines and frame profiles that keep the character of the house intact. The goal is always a double hung that looks like it belongs there and performs like it was made last week.
Vinyl Windows
Vinyl windows are framed with rigid PVC, which never rots, never needs painting, and costs significantly less than wood or fiberglass cladding, making them the most popular replacement window in Austin by a wide margin. They work in nearly every room and every style of home, and modern vinyl from lines we carry like ECO Window Systems and Mr-Glass has tight welds, multi-chambered frames, and solid thermal performance. Most vinyl window installations in Austin run $450 to $1,400 per unit installed, which is why they’re the right call for most whole-home replacement projects. Westlight Windows Austin gives you a written price before anything gets ordered, so you know the number before you decide.
Frame Construction and Welded Corners
The difference between a good vinyl window and one that fails in five years usually comes down to two things: the quality of the vinyl compound and whether the corners are welded or screwed. We only carry lines that use fusion-welded corners and multi-chambered extrusion, which resists warping in direct Austin sun and stands up to the thermal expansion and contraction that comes with hundred-degree summers and thirty-degree freezes. Cheap vinyl flexes, gaps, and eventually leaks; good vinyl doesn’t move.
Color Options Beyond Builder White
Vinyl doesn’t have to be white. Several manufacturers we stock offer solid-color vinyl in earth tones, bronze, and dark finishes that hold up without needing paint, which is a serious consideration in neighborhoods like Tarrytown and Rollingwood where HOAs have appearance standards. If you want a specific exterior color, we’ll show you what’s actually available in the product line before you fall in love with a rendering that doesn’t exist in the real world.
Picture Window
A picture window is a fixed, non-operable window designed to do one thing: bring in light and a view without any moving parts, mullions, or frames breaking up the glass. They’re the centerpiece window in a living room or great room, often flanked by casements or double hungs, and they make the most sense when you have a view worth framing in the Hill Country or a room that needs all the daylight it can get. Most picture window installations in Austin run $400 to $2,400 installed depending on size, with larger fixed units requiring tempered glass and heavier frames that push the number up. We’ll walk you through exactly what your opening needs, in plain words, before you sign anything.
Tempered Glass Requirements
Building code in Austin requires tempered safety glass for any fixed window sitting close to a door, low to the floor, or within a specific distance of a stair landing or walkway. We check every picture window opening against current code at the quote stage and include any required tempered glass in your written price, so there is no mid-job call about an unplanned upgrade. This is the kind of thing that separates a real window contractor from someone who just swaps in glass and hopes no one notices.
Framing a Hill Country View
Austin’s best views run west, and that’s where the name Westlight comes from: the late-afternoon sun that pours through a good window, bright, warm, and worth doing right. A picture window facing west needs serious low-e glass and thoughtful placement to keep the room from becoming a solar oven in August, and we’ll help you spec it so you get the view without the heat. The right fixed window isn’t just glass in a hole; it’s a decision about how the room feels at 6 p.m. every single day.
Bay Window Installation
Bay window installation means cutting back the exterior wall, framing a new structural opening with a header and support system, and setting a three- to five-panel window unit that projects outward to create usable interior space and a distinct architectural feature. It’s the biggest structural window job most Austin homeowners will ever do, and it requires a crew that understands load-bearing walls, flashing, and roof integration, not just window setting. Bay window installation in Austin typically runs $3,200 to $8,500 all-in, including framing, drywall repair, exterior siding or brickmold work, and the window unit itself. Westlight Windows Austin has done bay window installations from Leander down to Buda, and every single one starts with a written, itemized price.
Structural Headers and Support
A bay window isn’t a replacement job; it’s a remodel that touches structure. The existing header usually needs to be replaced or reinforced, the cantilever needs proper support, and the roof or overhang above the unit has to be flashed correctly or the whole thing becomes a leak liability. Our crews handle the framing, the flashing, and the finish work in-house, and we include all structural costs in your quote so there’s no surprised change order when the sawzall comes out.
Bump-Out Options and Seat Boards
Most Austin homeowners want either a deeper bench seat with storage below or a shallow bump-out that adds just enough floor space for plants and cats to live happily. The depth of the projection, the roof line treatment, and the window configuration all change the final price, which is why our quotes are based on a site visit and not a square-footage formula. You’ll see the line items, you’ll understand the line items, and you’ll approve the line items before a single screw turns.
Window Contractor
A window contractor is the licensed, insured professional who handles the full installation: measuring, ordering, removing old units, setting new ones, insulating, flashing, trimming, and hauling away the debris. In Austin, where high heat, humidity, and occasional hail test every penetration in a home’s envelope, the difference between a good window contractor and a bad one shows up as drafts, leaks, and condensation within the first year. Westlight Windows Austin is an independently owned and operated Kingswell location that has handled residential window installation across the Austin metro since 2009, with background-checked, uniformed technicians on every job and a written guarantee on every completed install.
Licensed, Insured, and Accountable
We carry the insurance and the paperwork that protects your home and your wallet. The Kingswell Guarantee isn’t a marketing line; it’s a written document handed to every customer at job completion, and it says in plain language what happens if something fails: we come back and fix it at no charge. That guarantee covers workmanship and the products we install, and the 365-Day Done Right Promise means if it’s not right within the guarantee period, we make it right.
Written Price Before Work Starts
The most common window contractor horror story in Austin is the quote that doubles once the old window comes out and the rot is revealed. We handle that differently. When we find rot, framing damage, or code issues during the quote, we identify them before we quote, because we do a real site inspection, not a drive-by. The price Owen hands you is the price on the final invoice, and if the work doesn’t go right, the free second visit is automatic, no negotiating required.
Window Installers
Window installers are the people who actually do the work, and in Austin, the quality of your window installation matters exactly as much as the quality of the window itself, because a great window set badly is still a bad window. At Westlight Windows Austin, every installer is a background-checked, uniformed employee of our team, not a subcontractor we found on an app the week before your job. We’ve been installing windows in homes from Georgetown to Bastrop since 2009, and every crew member follows the same Kingswell Way on site: respect the house, protect the floors, clean up completely, and don’t leave until the window is right.
Background-Checked Crews You Can Trust
When we say background-checked, we mean every person who walks through your door has passed a screening before they ever put on a Westlight uniform. You’ll know who’s coming, when they’re coming, and what they’re doing. For homeowners who have been burned by no-shows and strangers in their homes, this is the single biggest reason they call us back for the next project or refer us to a neighbor on the same street.
Site Cleanup and Disposal Standards
Old window sashes, broken glass, trim offcuts, and packaging never stay on your property. Our crews haul everything away and leave the worksite cleaner than they found it, which is a specific promise inside the Kingswell Guarantee, not a goal we aspire to. If you’ve ever picked staples out of a rug or glass chips off a windowsill after a contractor left, you understand why this matters.
Brands We Service
We install windows from eight manufacturer lines because no single brand is right for every Austin home. PGT and CGI are our go-to impact-rated lines for homes that need storm protection and security in hail-prone or exposed areas, and we’ve installed both across the Texas Hill Country, where code requirements for wind and impact resistance can change from one neighborhood to the next. The hardware, the glazing, the mounting requirements: our crews know these products inside the frame, not from a product brochure.
Therma-Tru is our trusted entry-door line, often paired with sidelight windows or transoms that complement new window packages in a whole-home refresh. ViewLux and ECO Window Systems round out the lineup for energy-conscious Austin homeowners who want strong thermal numbers without paying for a luxury brand name. Whatever you have, whether it’s a PGT unit installed ten years ago or a builder-grade window from a brand we don’t even carry, we can assess it, repair or replace it, and stand behind the work.
If you’re unsure what brand or line makes sense for your house, that’s exactly what the free estimate is for. You can also start with our home page to see the full scope of what we do.
Signs You Need a Pro Right Now
- Condensation between the glass panes. It means the seal has failed and the inert gas between panes has escaped. The window’s thermal performance is gone, and no amount of new weatherstripping fixes it. The only real solution is replacement of the glass unit or the entire window.
- Noticeable drafts around the window frame. Run your hand along the edges on a windy day. If you feel moving air, the installation or the window itself has failed, and you’re paying to condition the outdoors. In Austin summers, that’s real money on your electric bill every month.
- Windows that stick, rattle, or refuse to stay open. This is usually a sign of frame warping, failed balance systems, or structural settling. It’s also a safety issue: a double hung that slams shut on a child’s fingers isn’t a quirk, it’s a hazard that needs professional attention.
- Soft wood, visible rot, or peeling paint around the frame. Water is getting in somewhere, and where there’s rot, there’s often hidden damage to the rough opening beneath. Letting it go means the repair gets more expensive every month, and the window itself may be past saving.
- Single-pane glass in an Austin room. Single pane windows are functionally obsolete in this climate. Replacing them is one of the fastest ways to cut energy costs and make a room feel comfortable year-round, and the math on replacement versus continued cooling losses is rarely close.
Our Process, Step by Step
- 1
You call, a person answers. Our phone lines are staffed by a live, local team member 24 hours a day, 7 days a week, so you’ll never leave a voicemail and wait for a callback that might not come. During that call we’ll ask a few questions about your home, your windows, and your goals, and schedule a site visit that fits your schedule, not ours.
- 2
We measure, inspect, and quote in writing. Owen or a senior technician walks the property, measures every opening, checks for rot and code issues, and talks through your options in plain words, with real prices. You get a written quote with line items, not a handshake and a promise. That price is the price.
- 3
You approve, we order, we schedule. Once you approve the quote, we place the order with the manufacturer and lock an installation date and arrival window. No deposit games, no “your materials are still on a truck somewhere.” You’ll know when your windows arrive and when we’re coming.
- 4
Installation day. Our uniformed, background-checked crew arrives in the window we gave. Floors get protected, the old windows come out carefully, any hidden rot gets addressed, and the new units go in with proper flashing, insulation, and leveling. We treat your house like it belongs to somebody who lives there.
- 5
Walkthrough and written guarantee. Before we leave, we walk the job with you, show you the work, and hand you the written Kingswell Guarantee. If anything isn’t right, we fix it before we leave. If something fails later, the 365-Day Done Right Promise means we come back at no charge.
How Much Does Window Installation Cost in Austin?
A typical single vinyl window installation in Austin runs $450 to $1,400 per unit, while premium material windows like wood-clad or impact-rated PGT units land between $900 and $2,400 per opening. Double hung replacements usually fall in the $550 to $1,850 range, casements between $700 and $2,200, and a full bay window installation with structural work can run $3,200 to $8,500 depending on depth, roofline, and finish work. These are the numbers we quote from every week in neighborhoods across the Austin metro.
Several factors move the price: the material and glass package you choose, the size and quantity of windows, whether the opening needs any rot repair or reframing, and whether code requires tempered or impact-rated glass. Older homes in central Austin neighborhoods like Bouldin Creek or Travis Heights are more likely to have hidden framing work than a 2015 build in Cedar Park. The best way to avoid overpaying is to get a written, itemized quote from a contractor who does a real site inspection, not a drive-by. Our free estimates include exact measurements, a full scope of work, and the real number you’ll pay. Call (254) 322-3468 to schedule yours. You can also compare what we do with our service in Window Installation in Leander to see how our pricing holds up across the metro.

Frequently Asked Questions About Window Installation in Austin
Window installation is the full process of measuring an opening, removing the existing window, preparing the rough opening, and setting and sealing a new window unit so it’s level, plumb, insulated, and weather-tight. It includes flashing, shimming, insulation, interior and exterior trim work, and proper disposal of the old window. At Westlight Windows Austin, every installation follows the Kingswell Way and ends with a written guarantee.
Most single window replacements take one to three hours per opening, so a full house of ten to fifteen windows is usually completed in one to two days. Bay window installations with structural work typically take two to three days including trim and exterior finish. We’ll give you a specific timeline in your written quote before any work is scheduled.
For most Austin homes, expect to pay $450 to $1,400 per standard vinyl window installed, $700 to $2,200 per casement, and $3,200 to $8,500 for a full bay window installation with structural work. Your exact price depends on window size, glass package, frame material, and whether any rot repair is needed.
