Window Installation in Austin - Free Measure, Exact Written Quote

Trusted Window Installation for Austin Homeowners

Window installation in Austin means dealing with heat, humidity, and the occasional hailstorm, all of which punish a poorly sealed or badly fitted frame within a season or two. We’ve been installing windows across Austin since 2001, and the single most common call we get is from a homeowner who notices condensation between panes, a sash that will not stay up, or an electric bill that climbs every July. A new window, installed correctly, fixes all three. Led by Sean Mackey, Juniper Windows Austin handles the full job: measuring, ordering, removing the old unit, and sealing the new one to the manufacturer’s spec. Call (325) 420-1750 for a free, written estimate before any work begins.

Key Takeaways:

• Window installation in Austin typically runs $450 to $1,400 per window, depending on style, material, and frame condition.
• Every Juniper job gets a written price first, and the 365-Day Done Right Promise covers parts and labor for a full year.
• We stock and install PGT, Therma-Tru, ViewLux, and other product lines, so you’re never pushed toward a single brand.
• Live phone support is answered 24/7, and you track your installer’s arrival time in real time.

Casement Windows

Casement Windows are hinged on one side and crank outward, giving you a full, unobstructed opening and a tighter seal than a sliding sash can manage. They work particularly well over kitchen sinks, in hard-to-reach spots, and anywhere Austin’s prevailing winds can push against a window and create a draft. Juniper Windows Austin installs casements with a written price before work starts, and typical replacement costs in Austin run from $500 to $1,200 per unit depending on size and glass package. The 365-Day Done Right Promise covers every casement we hang, parts and labor, in writing.

The crank and hinge set

Casements live or die by their hardware. We check every crank operator, hinge arm, and locking point during installation, because a casement that binds after six months is almost always a hinge that was never adjusted to carry the sash weight. In Austin’s clay soil, slight frame settling is normal, and we account for it on day one.

Where we recommend them

Over counters, in bathrooms, and on second-story walls where reaching a double hung is awkward. The crank mechanism makes them easy to open without leaning or lifting.

Double Hung Windows

Double Hung Windows have two sashes that slide vertically, and both the top and bottom panels tilt in for cleaning. They are the default choice for two-story Austin homes and for any room where you want ventilation without a sash swinging into a walkway or porch. Installing a double hung correctly means balancing the sash weights or springs so the window stays put wherever you leave it, which matters more than homeowners expect. In Austin, double hung window installation runs $450 to $1,100 per window, with the final number set in writing before we order anything.

Tilt-in cleaning and maintenance

Both sashes tilt inward, so second-floor windows get cleaned from inside the house. We show every homeowner how to release the tilt latches during the final walkthrough, because a window you can clean is a window you will maintain.

Draft and balance correction

A double hung that slams shut or creeps up on its own has a balance problem. During installation we set the tension to the sash weight, which stops both problems and keeps the weatherstripping from wearing unevenly.

Vinyl Windows

Vinyl Windows are built with extruded PVC frames, which means no rot, no repainting, and no corrosion, all of which matter in a climate like Austin’s where wood frames swell and shrink with humidity swings. They are the most budget-conscious option we install, and they perform well when the frame is reinforced properly and the glass package is matched to the sun exposure on each side of the house. Juniper Windows Austin installs vinyl windows starting around $400 and up to $900 per opening, with a written price that locks in before installation day.

Reinforcement and warping

Cheap vinyl frames warp in direct Texas sun if the manufacturer skimps on internal stiffeners. The vinyl lines we carry from our eight product lines use metal or composite reinforcement in the frame and sash, so south-facing windows stay square through August heat.

When vinyl is the right call

Rental properties, guest houses, and budget-driven full-home replacements are where vinyl makes the most sense. You get a factory finish that never needs paint and a frame that never rots, at the lowest installed cost we offer.

Picture Window

Picture Window refers to a fixed, non-operable unit that does not open, designed to maximize glass area and pull in light and a view. Austin homes with a good backyard, a greenbelt view, or a vaulted living room are natural fits, and the tradeoff is simple: no ventilation, but also no moving parts to fail and the best rain and air seal available. We install picture windows for $400 to $1,100 per window depending on size and whether you choose standard, low-E, or impact-rated glass. Every quote is written and itemized before any work starts.

Glass package matters most

A fixed window is all glass, so the coating and gas fill do the heavy lifting. We spec low-E coatings and argon fill as the default on west-facing Austin walls, where afternoon sun can push cooling costs up fast.

Why a picture window never leaks

No sashes, no tracks, no weep holes. The frame is sealed fully to the rough opening, and the only potential leak points are the perimeter, which is exactly where our installers apply flashing and backer rod.

Bay Window Installation

Bay Window Installation projects a window out from the exterior wall, usually with a center fixed pane and two operable flankers, creating a small shelf of floor space and a lot more light. The structural part is what separates a good bay from a sagging one: the unit needs a proper support frame beneath it and secure attachment to the wall at the top. In Austin, bay window installation runs $1,500 to $3,500 for a typical three-panel unit, with the exact figure set in writing after we measure and inspect the existing opening. Sean Mackey and the installation team handle the structural work, not just the window.

Structural support and cantilever

A bay window hangs beyond the wall line, so it needs knee braces or a cable support system to carry the load. We inspect the rim joist and add reinforcement where Austin building practice requires it, because a sagging bay will eventually pull away from the house.

Interior and exterior finish work

The window is only part of the job. We seal the underside, cap the exterior, and finish the interior sill so the new bay looks like it was always there. The written price includes this finish work, so there is no surprise line item after the fact.

Window Contractor

A Window Contractor is the person or company responsible for the full installation: demolition, flashing, setting, trimming, and sealing. Choosing the right window contractor in Austin matters more than the brand of window you buy, because a quality window installed poorly will fail faster than a mid-grade window installed correctly. Juniper Windows Austin works as a specialist inside the Relay Home Co. family, meaning we do windows and doors only, no general remodeling, and every project gets a written price before a single screw turns. We are state-licensed and insured, led by Sean Mackey, and we have been setting windows in Austin since 2001.

Our window-only focus

We do not bid kitchens. We do not pour concrete. We install and replace windows and doors, which means the crew that arrives at your house does this work every day, not once a month. That specialization shows up in faster installs and cleaner flashing details.

The written price guarantee

Every quote is a fixed, line-item price. If an unexpected condition appears when we open the wall, we stop, show you photos, and agree on any change in writing before proceeding. No change orders appear at the end.

Window Installers

Window Installers are the crew members who actually remove the old window, prepare the rough opening, set the new unit, and seal the perimeter. This is the most detail-heavy part of the trade: a window is only as good as the flashing, foam, and caulk line that surrounds it, and Austin’s thunderstorms will find every weak point within a season. Our window installers are background-checked, uniformed, and trained on every product line we carry, from Therma-Tru doors to PGT impact windows. You will know exactly who is coming to your door, and you can track their arrival through the Relay Visibility Guarantee.

Who shows up at your door

Every installer is a Juniper employee, not a subcontractor we met last week. They arrive in company uniform, introduce themselves, and walk you through the day’s plan before unloading any tools. The live arrival time you get is the actual time, not a four-hour window.

Flashing, foam, and seal

The most common installation mistake is skimping on the perimeter seal. We use flashing tape at the sill and jamb, low-expansion foam around the frame, and a tooled exterior caulk line. An Austin downpour should hit that window and find no path inside.

Brands We Service

We carry more product lines than most Austin window companies, because a single brand cannot be the right answer for every house and every budget. PGT windows are a go-to for impact-rated glass, the kind built to resist wind-borne debris without shattering, and we install their full line for homeowners who want the strongest storm protection available. Therma-Tru is our primary door line, and we pair their entry doors with sidelites and transoms when a window replacement project turns into a full entryway upgrade.

ViewLux gives us a premium vinyl and aluminum line with clean sightlines and solid thermal numbers, useful when you want a modern look without stepping up to custom pricing. Whether you have PGT, Therma-Tru, ViewLux, or any other make, we can help. We also carry CGI, CWS, ES Windows, ECO Window Systems, and Mr-Glass, so the right window for your project is never a compromise.

Signs You Need a Pro Right Now

• You feel a draft even when the window is closed and locked. Air is moving through the frame or around the glass, which means the seal has failed or the window was never flashed properly. In an Austin winter, drafts push your heater to run longer, and in summer they let conditioned air escape.
• Condensation or fog appears between the panes. Double-pane windows have a sealed air space, and moisture inside it means the seal is broken. The glass is no longer insulating, and the only real fix is replacement, not drilling holes or defogging.
• The sash falls, sticks, or will not stay open. Balance springs wear out, and a sash that slams shut can injure fingers or crack the frame. A window that will not open is also a safety issue in an emergency.
• You see daylight around the frame or water stains on the interior wall. Either the flashing has failed or the window was never sealed correctly. Water intrusion around a window frame leads to mold and rot quickly in Austin’s humid months.
• Your energy bill jumped without a change in behavior. Windows account for a large share of a home’s heat gain in July. If the glass feels warm to the touch from the inside, the low-E coating may be failing or the unit may simply be old single-pane glass.

If any of these sound familiar, call (325) 420-1750 and we will inspect the window and give you a straight answer, with a written price if replacement is needed.

Our Process, Step by Step

1. 1
   Free on-site measurement and inspection. We visit your Austin home, measure each rough opening, and inspect the existing frame, flashing, and surrounding drywall for signs of water damage. This is where we catch problems that would otherwise become surprise change orders later.
2. 2
   Written, line-item price. You get a fixed price in writing that covers the windows, materials, labor, flashing, and finish work. If anything changes later, we document it in writing and get your approval before proceeding.
3. 3
   Scheduling with live arrival tracking. You book a date and time, and on installation day you get a live arrival time you can track from your phone. No four-hour windows, no guessing.
4. 4
   Removal, setting, and sealing. Our installers remove the old unit, prep the opening, set the new window level and square, and seal the perimeter with flashing tape, foam, and exterior caulk. We take before-and-after photos so you can see the work even if you are not home.
5. 5
   Final walkthrough and digital invoice. We walk you through each window, show you how the locks, tilts, and cranks work, and answer any questions. You receive a digital invoice you can pay from a link, and the 365-Day Done Right Promise is documented on your job file.
