Fast, Reliable Window Installation Across Keller
Window installation in Keller usually means working with a house built between 1993 and 2012, where the original builder-grade units are now failing together. Our crews know the 76244 and 76248 neighborhoods, the clay soil under them, and the out-of-square openings that come with it. If you’re pricing replacement windows or a door that binds in July, call (888) 635-0804. We’ll give you a written line-item quote, not a guess.
Why TruePane Windows & Doors Is Keller’s Preferred Window Installation Company
Dale Kessler founded TruePane in 2008 on a rule that still governs every install: if the pane is not true, the job is not done. In Keller, “true” means something specific – it means shimming a rough opening that clay movement has pushed half an inch out of square, and it means checking the reveal on a picture window until it is right.
Keller homeowners tend to keep their houses for decades. They remember the contractor who left them with a fogged seal and a door that catches in the summer. Our crews are background-checked, uniformed, and trained to work the way they would in their own mother’s house. We answer the phone 24 hours a day, 7 days a week – a live person, not a voicemail tree.
We are an authorized installer for more than a dozen manufacturer lines, including, and PGT. We quote side by side on paper so you see exactly what you’re buying. Both manufacturer warranty layers get registered in writing before the truck leaves your driveway. That’s the Keystone Standard, and it comes with every job.
Our Window Installation Services in Keller
Fixed & Picture Windows
Keller’s two-story great rooms were built around large picture windows. Twenty-five years later, many of those original units are losing their argon fill, and the low-E coating is breaking down under 100°F-plus summers. We replace them with fixed or picture units sized to the opening – including openings that have shifted out of square and need shimming and re-framing before the new unit goes in. In a Keller master-planned subdivision, that’s not the exception. It’s the standard.

Casement Windows
Casement windows seal tighter than double-hungs because the sash presses against the frame when closed. In Keller’s shrink-swell clay, that matters. A properly shimmed casement window installed in a racked opening will still operate smoothly years later. Our crews carry extra shim stock on nearly every Keller call because we’ve learned to expect the rough opening to measure out-of-square by as much as half an inch.
A typical casement window installation in Keller runs $650-$1,250 per unit for a mid-range vinyl line, or $1,100-$2,200 for Andersen or Marvin. The price includes working around what the clay did to the opening.

Bay & Bow Windows
Bay and bow windows project out from the house, which means the framing has to carry more load over a cantilevered span. In Keller, where foundation movement is a fact of life, the roof and floor support under a bay window need to be checked before the opening is enlarged. We frame, flash, and set the unit so the projection stays true. If the seat board isn’t level, the glass won’t sit right, and you’ll feel the draft within a season. A bay window installation in Keller typically runs $3,800-$7,500, depending on size and manufacturer.

Single & Double Hung Windows
Double-hung windows are the most common replacement in Keller’s 1990s and 2000s homes. The original builder units were mostly vinyl with fusion-welded corners. After two decades of clay movement racking the frames, those corners crack, the sashes bind, and air leaks through the jamb. We install single and double hung windows with new construction or retrofit flashing, whichever the opening requires. Expect $550-$1,100 per unit for mid-range vinyl, more for premium lines.
We also handle Window Installation work for sliding windows, awning windows, garden windows, and basement windows throughout the Keller area.

Trusted Brands We Service in Keller
We stock parts and service windows from PGT, CGI, and Ply Gem, among others. For Keller customers with homes built in the 1990s and 2000s, PGT is a common original line we see failing now. CGI’s impact-rated products are often a good fit for Keller homeowners who want storm and hail protection as part of the replacement. We’ll quote these side by side on paper so you can see the numbers honestly. And if you have a brand we don’t list, ask – we’ll tell you whether it’s worth repairing or replacing.
Common Window Installation Problems We See in Keller Homes
- Out-of-square rough openings from Blackland Prairie clay. The expansive soil under Keller shrinks in drought and swells in deluge. That movement racks window frames, and a new double-hung installed without shimming will bind at the jamb within a season or two.
- Fogged insulated glass units in homes built 1993-2012. The original builder-grade windows in Keller are reaching end-of-life together. The IGU seals fail, the argon fill escapes, and you’re left with glass that fogs between the panes and won’t insulate.
- Cracked vinyl frames at fusion-welded corners. When the frame racks, the corners – the weakest point – crack. You can caulk them, but the window is losing its structural seal. It needs replacement, not patching.
- Warped door sills and cracked sweeps from North Texas weather swings. Keller’s 100°F-plus summers degrade vinyl and wooden components. Infrequent but severe ice events – like February 2021 – warp wooden sills and crack sweeps that were never designed for sustained sub-zero wind chills.

FAQs - Window Installation in Keller
Keller sits on Blackland Prairie clay, which expands when wet and shrinks when dry. That seasonal movement racks the rough openings in homes built between 1993 and 2012, and a surprising number of them are out-of-square by half an inch or more. We shim and re-frame before installing the new unit. A window set into an out-of-square opening without correction will bind, leak air, and fail its warranty within a few years. Call (888) 635-0804 if you suspect the clay has shifted your frames.
Yes, in most cases. Fog between the panes means the insulated glass unit seal has failed, the argon fill is gone, and the window has lost its insulating value. On a 20-year-old builder-grade vinyl unit in Keller, the frame has usually also absorbed enough UV and thermal stress that replacing just the IGU is a short-term fix. We’ll look at the frame condition and give you an honest answer. Call (888) 635-0804 for an assessment.
Andersen and Marvin orders typically run 6 to 12 weeks from order date to delivery at your Keller home. PGT and Ply Gem are often shorter. The lead time is set by the manufacturer, not by our schedule, and we won’t pretend otherwise. We fix your price in writing before we order. That means the number doesn’t move while you wait. Call (888) 635-0804 and we’ll walk through current lead times for the lines you’re considering.
Keller’s 100°F-plus summers and roughly 2,300 cooling degree-days per year mean you want a low solar heat gain coefficient – something around 0.25 or lower – to keep the air conditioning from fighting the glass. A U-factor around 0.30 or below handles the winter end. We’ll quote options side by side so you can see how much each performance spec changes the price. Call (888) 635-0804 for exact ratings on the lines you’re considering.
They can be, but only if the framing under the projection is checked first. A bay or bow window cantilevers out from the wall, and Keller’s clay movement puts real stress on that cantilever. We check the load path, shore up what needs shoring, and then set the unit. Done right, a bay window in a Keller great room adds light and space that hold up for decades. Done wrong, it sags and leaks. Call (888) 635-0804 and we’ll tell you if your foundation is a candidate.
For window installation in Keller, TX, the difference comes down to whether the crew knows what the clay does. We know. Call (888) 635-0804 to schedule your free estimate. We’ll measure twice, quote on paper, and register both warranty layers before the truck leaves your driveway. If the pane is not true, the job is not done.
