Window Replacement in Austin - Written Price Before Anything Is Ordered

Trusted Window Replacement for Austin Homeowners

Window replacement in Austin means swapping out old, failing, or drafty windows for new units that seal tight, open smoothly, and handle Central Texas heat without fading or warping. Homeowners across Hyde Park, Allandale, and Circle C reach out to us most often because a window has fogged between the panes, a frame has rotted from years of humidity, or a room simply will not cool down in August. Westlight Windows Austin has been doing this work since 2009, as an independently owned and operated Kingswell location, with technicians who show up in the window we gave and leave the site cleaner than they found it. Led by Owen Satterfield, our crews carry eight manufacturer lines so the right glass goes in the right house, not whatever happens to be on the truck. Every job starts with a written price before any work begins, and if the work is not right, we come back and fix it at no charge. Call (254) 322-3468 and a live person will answer, day or night.

Energy Efficient Windows

Energy Efficient Windows are units built with low-e glass (a thin metallic coating that reflects heat back out in summer and back in during winter), insulated frames, and tight seals that stop conditioned air from leaking through the sash. In Austin, where July and August routinely push past 100 degrees, this is the difference between an HVAC system that cycles normally and one that runs nonstop while the west-facing rooms still feel warm. We replace old single-pane and failed double-pane units throughout Austin with energy-efficient options from ECO Window Systems and PGT, matched to the sun exposure on each side of your home. A standard energy-efficient Austin Window Replacement typically runs $450 to $900 per window installed, depending on glass package, frame material, and whether the opening needs new construction or fits a retrofit.

Low-E Glass Packages

Low-e coatings are not all the same. For Austin’s climate, we specify a coating with a low solar heat gain coefficient, which blocks the infrared heat that turns a living room into a greenhouse by 4 p.m. The glass still lets in visible light, so rooms stay bright without the heat load.

Proper Frame Sealing

Even the best glass fails in a poorly sealed frame. Our techs pull the old unit, inspect the rough opening for gaps or rot, and use closed-cell foam and flashing tape before the new window goes in. Air infiltration testing after install confirms the seal is actually holding.

Window Repair

Window Repair is fixing a specific failure on an existing window rather than replacing the whole unit: a broken balance spring, a rotted sill, a crank that spins without moving the sash, or a latch that will not engage. Many Austin homes built in the 1980s and 1990s still have original aluminum or wood windows that have decades of service left in the frame, even if the hardware has worn out. We diagnose the exact point of failure and quote the repair in writing before any work starts, the Kingswell Way. Window repair in the Austin area typically runs $125 to $450 per window depending on the part and whether it is a single hung, double hung, casement, or sliding unit. If the repair fails within the guarantee period, we come back and correct it at no charge under the 365-Day Done Right Promise.

Hardware and Balance Systems

A window that slams shut or will not stay up usually has a failed balance system. We replace spiral balances, block-and-tackle systems, and constant-force coils with OEM-grade parts matched to the window’s weight and size, so the sash moves like it did when the house was built.

Sill and Frame Repairs

Austin’s humidity and occasional heavy storms take a toll on wood sills. Where the damage is contained, we cut out the rot, treat the remaining wood, and rebuild the sill with epoxy or new lumber before repainting. If the rot has reached the rough opening framing, we will tell you honestly that replacement is the better path.

Window Replacement Company

A Window Replacement Company is a contractor that specializes in removing old windows and installing new ones, handling everything from measuring and ordering to flashing, trimming, and cleanup. Choosing the right one in Austin matters because a bad install voids the manufacturer’s warranty long before the glass ever fails. Westlight Windows Austin has been replacing windows since 2009, and as part of the Kingswell network, every job gets a written price before work starts, a committed arrival window, a clean job site, and a written guarantee handed to the homeowner at completion. Full Window Replacement cost guide pricing in Austin typically runs $400 to $1,100 per window installed, varying by size, frame material, glass package, and whether we are doing a retrofit or a full-frame tear-out.

Eight Manufacturer Lines

We install PGT, CGI, CWS, ES Windows, ECO Window Systems, Mr-Glass, Therma-Tru, and ViewLux. That matters because a 1960s ranch in Brentwood has different needs than a new build in Mueller, and carrying multiple lines lets us match the product to the house instead of forcing the house to fit one brand.

Written Estimates, Never Revised

When Owen Satterfield or a Westlight technician walks your home, the price on the estimate is the price you pay. No door-step surprises, no revised invoices after the job is underway. That is the Kingswell Guarantee in writing, every time.

Window Glass Replacement

Window Glass Replacement is swapping out just the glass unit inside an existing frame, also called an insulated glass unit or IGU replacement. This is the right fix when the frame is still square and sound but the glass itself is cracked, fogged, or has a broken seal. In Austin, failed seals are the most common call we get: the telltale haze between the panes that will not wipe off, because it is condensation trapped inside the sealed unit. Replacing just the glass typically runs $175 to $400 per window in Austin, less than half the cost of a full unit replacement, and we match the new IGU to the existing frame dimensions and glass package. If the frame is warped or the sash is failing, we will tell you that glass-only replacement would be a short-term patch and recommend the honest option.

IGU Matching

We measure the exact thickness and dimensions of the failed unit, then order a replacement IGU with the same low-e coating and argon or krypton fill, so the new glass blends with the remaining windows and performs the same thermally. Mixing mismatched glass on one wall is a look nobody wants.

When Glass-Only Makes Sense

If your frames are aluminum or vinyl and still in good shape, glass replacement keeps the job fast and affordable. We do not push a full replacement when a glass-only fix solves the problem for the next decade, and we put that recommendation in writing before any work starts.

Window Sash Replacement

Window Sash Replacement means removing and replacing the movable part of the window, the framed panel that holds the glass, while the surrounding frame stays in place. This is the repair for sashes that have rotted at the corners, warped from years of Austin sun, or broken where the hardware attaches. We build or order replacement sashes to match the existing opening, often from the same manufacturer line if the window is still in production, and install them so the window operates smoothly and seals tight. Sash replacement in Austin typically runs $250 to $600 per sash, depending on size, material, and whether the glass is reused or replaced. It is a middle path between a glass-only fix and a full window replacement, and we will recommend it only when the frame is still solid.

Wood Sash Rebuilds

Older Austin neighborhoods like Travis Heights and Bouldin Creek have original wood windows worth preserving. We can rebuild a sash with new stiles and rails, reglaze the glass, and re-hang it with fresh hardware, keeping the historic look while fixing the function.

Vinyl and Aluminum Sashes

For vinyl and aluminum windows, a sash replacement usually comes from the manufacturer as a pre-built unit. We pull the old sash, drop in the new one, and adjust the balance system so it opens and closes with one hand.

Window Glass Repair

Window Glass Repair addresses damage to the glass surface itself: cracks, chips, scratches, and small impact breaks that do not yet require a full glass replacement. A hairline crack from a rock thrown by a mower or a chip from a storm-blown branch can be stabilized temporarily, but in most cases, the honest answer is that a cracked sealed unit will eventually fail completely as temperature swings in Austin stress the fracture. We assess the damage on site, tell you straight whether a repair will hold or whether a glass replacement is the responsible fix, and give you the written price either way. Minor glass repair in Austin typically runs $80 to $200 per window where the damage is cosmetic and contained; if the seal is compromised, we recommend IGU replacement instead.

Emergency Board-Up and Temporary Fixes

A shattered window is a security and weather exposure problem, not just an eyesore. We can board and seal the opening same day, then schedule the measured replacement so you are not waiting with plastic sheeting for a week. Live phone coverage means a real person answers at 2 a.m. when a window blows out.

Scratch and Haze Removal

Surface scratches from construction debris or pet claws can sometimes be polished out of uncoated glass. If the glass has a low-e coating, polishing risks damaging the coating further, and we will tell you that upfront rather than making it worse and billing you anyway.

Window Pane Replacement

Window Pane Replacement is the process of removing a single broken pane of glass and installing a new one, most common in older single-pane windows where each sash holds one sheet of glass. In Austin, single-pane replacement is often a stopgap for older homes until the homeowner is ready for a full energy-efficient upgrade, and we handle it with the same written-pricing guarantee as every other job. A single pane replacement in Austin typically runs $150 to $350 per pane depending on size and glass type, including glazing and cleanup. For double-pane windows, the pane is not replaceable on its own; the entire sealed unit must be swapped, which is why we always inspect the window type before quoting.

Single-Pane vs. Insulated Units

If you have single-pane windows, pane replacement is straightforward: score the broken glass, remove the old glazing, set the new pane, and reglaze. If you have double-pane or triple-pane windows, a “pane replacement” is really an IGU replacement, because the sealed unit cannot be opened and resealed in the field.

Upgrade Path from Single-Pane

Many Austin homeowners use a broken pane as the prompt to upgrade the whole window to an energy-efficient double-pane unit, following our Window Replacement Maintenance Checklist for Austin Homeowners. We will quote both the pane-only fix and the full replacement so you can decide with real numbers in front of you.

Window Seal Repair

Window Seal Repair refers to fixing the failure of the seal that keeps moisture and air out of a double-pane or triple-pane insulated glass unit. When a seal fails, the window fogs between the panes, and no amount of cleaning the exterior glass will fix it, because the condensation is on the inside of the sealed unit. In Austin’s climate, seal failures are accelerated by extreme heat cycles that expand and contract the sealant around the glass. The honest answer is that a failed seal on an IGU usually means replacing the glass unit, since the seal cannot be re-applied in the field; we quote glass replacement, not a patch, and the new unit carries a manufacturer-backed seal warranty. IGU replacement for seal failure in Austin typically runs $200 to $450 per window.

Fogged Glass Diagnosis

We confirm seal failure with a moisture meter and visual inspection, not guesswork. If the fogging is between the panes, it is a seal failure. If it is on the room-side surface, it is a humidity issue in the home, and we will tell you the difference instead of selling you a glass unit you do not need.

Preventing Future Seal Failure

New IGUs from PGT and ECO Window Systems use dual-seal construction, a primary polyisobutylene seal and a secondary structural sealant, that resists the thermal cycling Austin dishes out year after year. We also verify the frame drains are clear so water never pools against the glass edge.

Brands We Service

We install and service PGT windows, including their impact-rated lines that hold up to storm debris and their WinGuard series built for high-wind zones. Austin is far enough inland that impact ratings are optional for most homes, but the same laminated glass that meets coastal code also cuts noise from a busy street and resists forced entry, which matters in neighborhoods near I-35 or South Congress.

We also carry Therma-Tru entry doors and ViewLux window lines, giving homeowners a full exterior package from one installer. If you have a Therma-Tru door or a ViewLux window that needs service, we stock the hardware and know the installation specs. Most Austin homes have a mix of brands based on when different rooms were updated, and we service whatever mix you have, whether that is PGT, CGI, Therma-Tru, or any other make we carry.

Signs You Need a Pro Right Now

• Fog between the panes. That haze you cannot wipe off the inside means the seal on your insulated glass unit has failed. The window has lost its insulating gas fill, and the fog will never clear on its own. The fix is a glass unit replacement, not a cleaning.
• Windows that will not open or close. A sash that needs two hands, props, or a shoulder to move has a failed balance or warped frame. It is also an escape route that may not work when you need it, which is a safety issue for any Austin home.
• Drafts you can feel with the window closed. Run your hand along the edges of the frame on a breezy day. If you feel air moving, the weatherstripping or the seal has failed, and that conditioned air you paid for is leaking straight out of the house.
• Visible rot or soft wood around the frame. Austin’s humidity and storm cycles will find any unpainted or cracked frame. Soft wood, peeling paint, or visible decay around a window means water is getting in, and the damage only spreads the longer it sits.
• Rising energy bills without a change in usage. If your Austin Energy bill keeps climbing and nothing else in the house has changed, failed window seals and worn weatherstripping are often the source. The windows are working against your AC from April through October.

Our Process, Step by Step

1. 1
   You call, a person answers. Our phone lines are staffed by a live person 24 hours a day, 7 days a week. No voicemail tree, no chatbot, no “we will get back to you within one business day.” You tell us what is going on, we ask the right questions, and we schedule a visit at a time that works for you.
2. 2
   We measure and assess on site. Owen Satterfield or a trained Westlight technician walks the property, measures each opening, checks the condition of the frames and rough openings, and talks through what you are seeing from inside the house. We use a moisture meter and inspect the drainage plane, not just the visible frame.
3. 3
   You get a written price before any work starts. We write down the exact scope, the exact products, and the exact price, and we hand it to you. There is no verbal “ballpark” and no revised invoice after the truck is unloaded. The Kingswell Way is to say the price before the work, every single time.
4. 4
   We install and clean up. The crew shows up in the committed arrival window, lays down floor protection, removes the old windows, and installs the new ones to manufacturer spec, with flashing and sealing done right. When the job is done, we haul off the old units and leave the site cleaner than we found it.
5. 5
   We hand you the written guarantee. Before we leave, you receive the Kingswell Guarantee in writing, covering the workmanship and the installation. If anything is not right within the guarantee period, under the 365-Day Done Right Promise, we come back and fix it at no charge. No forms to file, no warranty department to chase.
