Fast, Reliable Impact Windows & Doors Across Round Rock
Impact windows and doors in Round Rock typically run $1,100-$2,800 per opening installed, depending on the product line and the condition of your existing framing. Most Round Rock homes built between 1993 and 2012 sit on slab foundations over Williamson County black clay, which means we measure every opening twice and re-square frames before we set a single unit. If you’re in 78664, 78665, or 78681 and want a written line-item quote with both warranty layers registered in writing, call us at (888) 635-0804.
We’ve worked in Round Rock long enough to know what the Dell-era tract homes throw at you. The builder-grade windows in those brick-veneer houses are at the end of their serviceable life. The doors bind in August. The seals fail early under central Texas UV. Our crews know the subdivisions, the soil behavior, and the permit triggers before they ever knock on your door.
Why TruePane Windows & Doors Is Round Rock’s Preferred Impact Windows & Doors Company
TruePane was founded in 2008 by second-generation glazier Dale Kessler. We’ve built our name on a simple rule Dale keeps on the whiteboard: if the pane is not true, the job is not done. Round Rock homeowners tend to call us after another contractor walked away from a fogged seal or a door that binds every summer. We square up the opening, register both warranty layers, and stand behind the work with our Done Right Promise, backed by the Keystone Standard. You get the manufacturer warranty durations in writing before the truck leaves your driveway.
Our Impact Windows & Doors technicians are background-checked and uniformed. They measure every opening twice and quote manufacturer lines side by side on paper so you see exactly what you’re buying. A live person answers every call, 24 hours a day, 7 days a week. No voicemail tree. No callback form. No regional call center. When you call about impact windows and doors, you talk to someone who understands Round Rock soil and framing. That matters.
We don’t claim to be the cheapest bid in town. We aim to be the last call you make, and we act like a company that plans to be in Round Rock thirty years from now. We sponsor county fairs and church roof funds. We train apprentices into journeymen. We keep our word in writing.
Our Impact Windows & Doors Services in Round Rock
Hurricane Impact Windows
Hurricane impact windows for a Round Rock home make sense even though we’re 180 miles from the Gulf. The same laminated glass that handles windborne debris also blocks a meaningful amount of UV, which is the thing that kills glazing seals early in 78681. We install impact-rated windows from manufacturers including PGT and CGI, with low-E argon-filled units where the opening calls for it. Every unit gets flashed and shimmed to the rough opening, not to the old trim.

Impact Sliding Glass Doors
Impact sliding glass doors in Round Rock share one enemy: the slab. Williamson County shrink-swell clay heaves and settles, and a 12-foot sliding door track will show it first. We re-level the track and re-square the jamb before the new impact door goes in. If your slab has moved enough to put the frame out of true, we write that work into the quote on paper instead of discovering it after the old door is out.

Impact Entry & French Doors
Impact entry and French doors are where we see the most seasonal complaints in 78665. A door that won’t latch in August is almost always slab movement, not a hinge problem. We re-square the frame, reset the threshold, and set an impact-rated unit that won’t bind with the seasons. In Old Town Round Rock’s pre-1960s wood-frame homes near Mays Street and Sheppard Street, we also address settled headers and rotted jambs before the new door goes in. Those houses were built long before impact ratings existed, and the framing shows it.

Impact Garage Doors
Impact garage doors on a brick-veneer tract house in 78681 need to handle wind loads and whatever the clay does to the header. We install wind-rated doors and reinforce the opening to current code where the existing header was undersized. If your home was built during Round Rock’s Dell boom, there’s a good chance the garage header was spec’d for a standard door, not a heavier impact unit. We check before we quote.

Common Impact Windows & Doors Problems We See in Round Rock Homes
- Fogged insulated glass units. Round Rock’s 100°F-plus summers and intense UV degrade glazing seals faster than the manufacturer’s rating. We regularly see builder-grade dual-pane units failing in 15 to 20 years when they were rated for 25 to 30.
- Out-of-square door frames from clay-soil slab heave. In 78665 and 78681, a French door that binds or refuses to latch in late summer is almost always foundation movement from shrink-swell black clay. The original installation was often fine. The soil beneath it wasn’t.
- Air and water leaks at the jamb-to-rough-opening gap. The February 2021 hard freeze tested flashing tape and gap seals on slab-on-grade homes in ways they’d never been tested before. We found widespread seal failures after that week, and many of those gaps are still open today.
- Undersized framing headers. Dell-era tract homes were built fast, and some garage and door headers were spec’d for lighter units than an impact-rated product requires. A code-compliant replacement often means reinforcing the header before the new door or window goes in.

FAQs - Impact Windows & Doors in Round Rock
Williamson County’s black clay shrinks during Round Rock’s long dry summers and expands after fall rains, so slab foundations heave and settle seasonally. The door frame gets torqued out of square, and the latch stops lining up. It’s not an installation defect, it’s soil movement. We re-square the frame and set the new door to handle the seasonal shift. Call (888) 635-0804 for an inspection quote.
Yes. Fog between the panes means the seal has failed and the insulating gas has escaped. The fix for a Round Rock home is replacement, not repair. The old builder-grade vinyl from the Dell era wasn’t rated for our UV exposure anyway. We’ll quote you an impact-rated replacement with low-E argon, register both warranty layers, and write the durations down for you before the truck leaves.
Yes, and that’s the part most companies gloss over. Round Rock permits often trigger code upgrades once walls are open, including wind-load requirements and updated flashing details. We handle the permit, pull the wind mitigation documentation, and write allowances into the contract up front. If an inspector requires something we didn’t anticipate, we price it and get your written approval before we touch it. No change orders without your signature. Call (888) 635-0804 to talk through your specific home.
Yes, for two reasons that matter in our climate. The laminated interlayer blocks UV, which is the thing that kills glazing seals early under central Texas sun. And the stronger frames survive the slab movement better than builder-grade vinyl. We don’t sell impact products as hurricane insurance for Round Rock. We sell them because they last longer in the conditions we actually have here. Call (888) 635-0804 and we’ll quote both impact and standard lines side by side so you can judge the difference in writing.
It takes removing the trim, shimming the jamb back to plumb and square, refastening to the rough opening, and resetting the threshold. On pre-1960s wood-frame homes near Mays Street, it often also means repairing rotted jambs and adding new flashing tape. We won’t set a new impact door into an out-of-square frame, because it’ll bind within a year. We re-square first and show you what we found before the new unit goes in.
We replaced a fogged dual-pane casement with an impact-rated Simonton unit in a 2004 brick-veneer tract home in the Teravista subdivision off 78681, where the original builder-grade vinyl sash seals had failed after 20 years of Round Rock UV. The jamb had been torqued 3/8 inch out of square by clay-soil slab movement, so we re-squared the rough opening with new flashing tape and fusion-welded frame before setting the low-E argon-filled unit. That’s the job done right, and it’s what we do on every opening in this town. If the pane is not true, the job is not done. Call (888) 635-0804 to schedule your free estimate.
