AfterWindows & Doors in Round Rock, TX
Window installation in Round Rock is dominated by one recurring situation: subdivisions built between roughly 1995 and 2012 are now showing their age all at once, with builder-grade vinyl windows failing seals, frames oxidizing under Central Texas UV, and doors binding in frames that shift every summer on Williamson County clay. The work here is less about replacement for aesthetics and more about correcting two decades of cumulative thermal and structural fatigue. We write the measured survey and the quote as the same document, so you see the full price before any tool is lifted. Call (509) 265-6387 to schedule a measured survey in Round Rock.
Why Round Rock Homes Are Different
Forest Creek, Teravista, Paloma Lake, and Stone Canyon were not built as custom homes. They were built fast, by DR Horton, KB Home, and Lennar, using production-grade windows and doors that were never intended to carry a house past its 25th birthday. Most of those houses are turning that corner now, and the failures are predictable from the street: fogged double panes on south-facing elevations, chalky vinyl frames, and entry doors that only latch cleanly in certain months.
The soil underneath matters more than most homeowners expect. Williamson County’s expansive black clay shrinks during July and August, dropping slab corners enough to rack door frames out of square. A door that sticks at the top corner in August and swings fine in February is a foundation-movement symptom, not a hinge problem. In Round Rock, window and door work often has to account for frame geometry that is not going to stay fixed on its own. We measure for that.
Our Main Round Rock Services
Two services account for most of the calls from Round Rock: full window replacement driven by seal failure and frame oxidation, and door installation driven by out-of-square slabs and worn builder-grade hardware. Both start with a written, measured survey.
Door Installation in Round Rock
Door jobs in Round Rock fail on alignment before they fail on materials. The expansive clay under most production subdivisions moves door rough openings every dry season, so a replacement door has to be measured and set against that movement, not just swapped into an old hole. We install energy-rated exterior doors with re-shimmed frames and documented corner-to-corner measurements. Details: Door Installation in Round Rock.
Window Replacement in Round Rock
Most Round Rock window replacements are full-frame jobs, not sash-only inserts. The builder vinyl in late-90s and 2000s tract homes is too degraded to accept an insert cleanly, and the existing rough openings often need corrective flashing before any new glazing goes in. We quote written, all-in prices for full-frame replacement. Details: Window Replacement in Round Rock.

BeforeAfterWindow Installation in Round Rock
In Round Rock, window installation typically means full-frame replacement of builder-grade units that have hit the end of a 20-to-25-year service life across entire subdivisions at once. The households that bought new in Teravista or Forest Creek in the early 2000s are now the ones watching seals fog and frames warp in the same five-to-ten year window. This is where Window Installation gets specific: we want the frame condition recorded before we order anything, because the clay underneath the slab means a square opening today may not measure square in six months.
Single & Double Hung Windows
Signs you need it
Sashes that no longer stay up, visible condensation between panes, or springs that fail on lower sashes indicate tired single- or double-hung builds.
What it costs in Round Rock
Replacing a standard double-hung unit in Round Rock generally runs $490-$1,460 per window installed, with size and glass package moving the price.
How we do it
We remove the old frame to inspect the rough opening, correct any clay-related racking, set the new unit plumb, and photograph the completed install against the measured survey.
Casement Windows
Signs you need it
Crank mechanisms that grind or skip, seals broken at the sash edge, or frames that have twisted enough to let daylight through the stile.
What it costs in Round Rock
Casement window replacement runs $650-$1,850 per unit, with the higher end covering larger Western exposures where low-SHGC glazing matters most.
How we do it
We square the opening, install the new casement with adjustable hinges, and verify the weather seal around the full perimeter with the customer present.
What Window Installation Costs in Round Rock
| Item | Typical range in Round Rock |
|---|---|
| Single or double hung replacement | $490-$1,460 per window |
| Casement replacement | $650-$1,850 per window |
| 3-panel sliding window | $1,900-$4,300 per assembly |
Will the price change once work starts?
No. The written quote is based on the measured survey, and that survey is the binding document. If we find hidden rot or framing damage once the old unit is out, we document it, show you the evidence, and price any fix before proceeding.
How long does window installation take in Round Rock?
Most production homes with 8 to 12 openings are completed in 2 to 3 days for full-frame replacement. The schedule is written into your scope before work begins. Call (509) 265-6387 for a written estimate.
Impact Windows & Doors in Round Rock
Impact-rated windows and doors matter in Round Rock not because of coastal storm surge, but because a hardened envelope holds the house together in high wind and keeps debris out when a thunderstorm downburst hits a subdivision full of fences, roofing, and construction material. PGT and CGI lines are two of the brands we specify, with laminated impact glazing that stays in the frame after a strike instead of shattering into the living room. This is where Impact Windows & Doors crosses paths with the local housing stock: a mid-2000s DR Horton build can be made substantially more resilient without replacing framing.
Impact-Resistant Windows
Signs you need it
Frames that flex visibly when struck, or the fact that standard annealed glass offers essentially no barrier to windborne debris.
What it costs in Round Rock
Impact-resistant units typically run $900-$2,300 per window in Round Rock, with the glass type and frame construction setting the final number.
How we do it
We install the laminated glass unit into a reinforced frame, mull the assembly to the rough opening, and photograph the anchoring points before the exterior trim goes back.
Horizontal Roller & Sliding Impact Windows
Signs you need it
Older roller windows with single-pane glass and thin aluminum tracks that no longer meet even moderate wind-load expectations in a downburst zone.
What it costs in Round Rock
Impact sliding or roller assemblies in Round Rock start around $1,900 for smaller widths and run up to $4,300 per assembly depending on length.
How we do it
We replace the old track assembly, bed the new impact-rated unit in a square opening, and confirm that the operating panel interlock engages fully across the meeting stile.
What Impact Windows & Doors Costs in Round Rock
| Item | Typical range in Round Rock |
|---|---|
| Impact-resistant window | $900-$2,300 per window |
| Impact sliding door | $4,500-$9,800 complete |
| Hurricane-rated garage door | $2,400-$6,000 complete |
Are impact windows worth it in Round Rock if we are not on the coast?
Yes, because Central Texas thunderstorm downbursts carry the same debris load as milder coastal wind events, and standard annealed glass offers minimal protection. Impact-rated glazing also significantly reduces forced-entry risk for homeowners who care about the security side of the product.
Will impact windows change the look of my Round Rock home?
No. Modern impact laminated glass looks identical to standard glass from the street. The difference is in the interlayer and the frame engineering, not the appearance. Call (509) 265-6387 to see specifications in writing.
Energy-Efficient Windows in Round Rock
Round Rock’s 100-degree afternoons punish west- and southwest-facing glass on every subdivision east of I-35 and along SH 130, where solar gain turns a poorly glazed room into a convection oven by 4 p.m. Low-SHGC glass is not a luxury upgrade here; it is the difference between a cooling bill that spikes every August and one that tracks predictably. The relevant lens is Energy-Efficient Windows, and in Round Rock we start by reading the existing glass: original single-pane or early double-pane that reads as clear glass under a meter is doing almost nothing for the homeowner.
Low-E & Argon Gas Glass
Signs you need it
A room that heats up noticeably on west-facing elevations, or failed double-pane seals that have already let the argon escape between the panes.
What it costs in Round Rock
Low-E with argon fill typically runs $550-$1,700 per window in Round Rock, with larger fixed units at the upper end.
How we do it
We specify the Low-E coating by orientation, verify the U-factor and SHGC on the written quote, and install with continuous perimeter insulation to stop thermal bridging through the frame.
ENERGY STAR Replacement Windows
Signs you need it
Original builder windows from the late 1990s and 2000s that no longer meet current ENERGY STAR criteria for the South-Central climate zone.
What it costs in Round Rock
ENERGY STAR-rated replacement windows in Round Rock cost $550-$1,700 per unit installed, with product line selection driving the spread.
How we do it
We pull the model-specific performance tag for each window, write those ratings into your quote, and install the unit with the same weather resistive barrier detailing used on new builds.
What Energy-Efficient Windows Costs in Round Rock
| Item | Typical range in Round Rock |
|---|---|
| Standard double-pane, Low-E | $550-$1,700 per window |
| Energy-efficient picture or fixed window | $900-$3,400 per assembly |
| Solar/tinted glass package | $450-$1,850 per window |
Do energy-efficient windows actually reduce cooling costs in Round Rock?
They reduce solar heat gain, which is the largest driver of cooling load in Central Texas. The measurable difference is lower afternoon heat gain in west-facing rooms and a more stable indoor temperature. Exact savings depend on whole-house orientation and the existing HVAC system. Call (509) 265-6387 for a written analysis.
Which glass package is right for Round Rock’s climate?
For most Round Rock homes, a Low-E coating with an SHGC of 0.25 or lower and a U-factor under 0.30 is the functional starting point. We write the specific package into your quote after measuring the orientation and thermal exposure on site.
Sliding & Patio Doors in Round Rock
Sliding patio doors in Round Rock are among the first components to fail on expansive clay, because a long horizontal door cannot hide racking the way a single-hung window can. By the time a slider starts dragging on the track in a Teravista or Stone Canyon home, the frame has usually moved enough that simply replacing the rollers is a temporary fix. The Sliding & Patio Doors work we do here starts with measuring the opening diagonally in both directions, because the numbers tell us whether the slab has settled and by how much.
Patio Doors
Signs you need it
A slider that binds at the top corner in dry months, a track that pools water after rain, or daylight visible through the weatherstrip when the door is closed.
What it costs in Round Rock
Patio door replacement in Round Rock generally runs $2,100-$6,600 complete, with swing doors at the lower end and impact-rated sliders at the top.
How we do it
We square and reshim the rough opening, set the new door with corner-to-corner diagonal measurements within tolerance, and seal the pan with a continuous sill pan flashed to drain outward.
Sliding Glass Door Replacement
Signs you need it
Track wear that creates a grinding feel, failed seals between glass lites, or a frame that has been shimmed by a previous owner to compensate for visible racking.
What it costs in Round Rock
Sliding glass door replacement ranges from $2,100 to $6,600 depending on width, glass package, and whether the opening needs corrective framing.
How we do it
We remove the old unit, true the opening with structural shims, install the new slider, and record the diagonal measurements before the final trim goes on so the documentation matches the work.
What Sliding & Patio Doors Costs in Round Rock
| Item | Typical range in Round Rock |
|---|---|
| Sliding glass door replacement | $2,100-$5,200 complete |
| French patio door replacement | $2,500-$6,600 complete |
| Impact sliding glass door | $4,500-$9,800 complete |
Will a new patio door fix the sticking problem long-term in Round Rock?
Only if the opening is squared and reshimmed to account for the existing slab settlement. A door that is simply swapped into a racked opening will bind again within a year or two. We document the correction so you can see it. Call (509) 265-6387 to schedule a measurement.
What is the best patio door material for clay-soil areas like Round Rock?
Fiberglass and well-engineered vinyl doors resist the racking forces better than solid wood, which tends to twist seasonally on expansive clay. We will write the material choice into the quote with the documented frame measurements backing it up.
Impact Garage Doors in Round Rock
Garage doors are the largest unbraced opening on most Round Rock production homes, and in a downburst they are typically the first component to fail inward. Once the garage door goes, the pressure change can lift the roof framing above it. That is the structural case for Impact Garage Doors in Round Rock, and it is one most homeowners have never had written down before. CWS produces wind-load-rated garage doors we specify against the opening size and the exposure of your particular street.
Hurricane-Rated Garage Doors
Signs you need it
An unreinforced single-skin garage door on a west-facing elevation, or any garage door that flexes visibly when you press on it mid-panel.
What it costs in Round Rock
Hurricane-rated garage door systems in Round Rock typically run $2,400-$6,000 complete, including track and reinforcement struts.
How we do it
We install the rated door with pressure-rated track brackets, confirm the jamb anchoring point spacing, and document each reinforced connection in the photo record.
Garage Door Replacement
Signs you need it
A builder-grade door with broken springs, sagged panels, or a track system installed without wind-load reinforcement on a home in a wind-exposed area.
What it costs in Round Rock
Standard garage door replacement in Round Rock falls between $1,100 and $3,500 for most production-home double doors.
How we do it
We write the panel gauge and wind-load rating into the quote, remove the old hardware, install the new door with reinforced jamb brackets, and test the balance with the opener disconnected.
What Impact Garage Doors Costs in Round Rock
| Item | Typical range in Round Rock |
|---|---|
| Standard garage door replacement | $1,100-$3,500 complete |
| Hurricane-rated garage door | $2,400-$6,000 complete |
| Energy-efficient garage door | $1,500-$4,000 complete |
Do I need a wind-load rated garage door in Round Rock?
If your garage faces an open exposure and the door is an original builder unit, a wind-load rated replacement is the single largest structural upgrade you can make to the opening without reframing. We will show you the wind-load calculation for your house in the written scope. Call (509) 265-6387.
Will an impact garage door work with my existing opener?
Most openers work with a rated door, but heavier reinforcement struts may require a spring retensioning and possibly an opener horsepower check. We include that in the written quote so there are no surprises after the install.
Custom & Geometric Windows in Round Rock
Custom window work in Round Rock has a split personality. Some jobs are fixing uniquely shaped openings in high-end homes on the western edges of the city, and others are correcting the thermal performance of fixed picture windows that never should have been installed as single-pane spans across a west wall. Custom & Geometric Windows means we work from an actual template of the opening, not a standard unit size, because the glass has to match the hole that exists. ViewLux is one of our custom lines specified for geometric units.
Geometric & Shaped Windows
Signs you need it
A trapezoid, arch, or radius opening with a builder unit that never fit properly in the first place, leaving persistent air or water leaks at the corners.
What it costs in Round Rock
Geometric and shaped windows in Round Rock generally run $900-$3,400 per unit, with complex arcs and impact glass packages pushing toward the top.
How we do it
We template the opening directly, send the exact radius or angles to the manufacturer, and install the unit with the same flashing and seal method documented on every job.
Arched & Curved Windows
Signs you need it
Arched windows in brickveneer Round Rock homes with failed seals and no off-the-shelf replacement available without modifying the opening.
What it costs in Round Rock
Arched or curved custom windows run $900-$3,400 per assembly, with the top end reflecting true radius glazing work.
How we do it
We create a physical template of the chord and rise, order the curved unit to that profile, and install with a documented airtight perimeter seal.
What Custom & Geometric Windows Costs in Round Rock
| Item | Typical range in Round Rock |
|---|---|
| Custom geometric window | $900-$3,400 per assembly |
| Arched or curved window | $900-$3,400 per assembly |
| Oversized fixed picture window | $900-$3,400 per assembly |
Can you match the existing window in my Round Rock home exactly?
Yes, when the opening shape is standard enough for a templated order. When it is not, we document the mismatch and write the correct replacement specification before ordering. The quote will show exactly what you are getting. Call (509) 265-6387 for a free second opinion on any written estimate.
How long do custom windows take to order for Round Rock homes?
Custom geometric units typically take 4 to 8 weeks from template to delivery, depending on the glass package and whether impact glazing is specified. The schedule is written into your scope when we quote the job.
