Call (325) 420-4173

We’re not manufacturer-affiliated or authorized. We’re an independent ES Windows service provider, which means we don’t follow a replacement-only playbook. Our techs have worked on ES Windows Aluminum Single Hung, Horizontal Roller, Casement, and Fixed/Picture Window series across the San Antonio metro for years, and we bring that same depth of knowledge to every Schertz home we visit. From the original 1960s subdivisions near Main Street to the newer developments off FM 3009, we know what these windows do in this sun.

If your ES Windows are binding, leaking air, or fogging between the glass, call (325) 420-4173 for a free estimate. Keith Yamada and the crew at Lightwell Windows San Antonio will walk you through it.

Why Schertz Residents Choose Us for ES Windows Service

Keith Yamada grew up in Los Angeles and learned the fundamentals of the trade at Los Angeles Trade-Technical College, then spent nearly two decades working windows and doors across the Southwest. He keeps a small notebook on every job to write down which windows face west, because in San Antonio that afternoon sun is not something you want to guess about. That habit carries into every ES Windows service call we make in Schertz.

We know ES Windows products from the inside out. We’ve replaced warped aluminum sashes, rebuilt weatherstripping channels, swapped worn roller assemblies, and reglazed fogged insulated glass units on thousands of service calls across the San Antonio metro. We’re independent, so our recommendation isn’t shaped by a manufacturer’s replacement quota. If the frame is square and the glass is intact, we’ll repair it.

Our ES Windows sales & service work is built on the Cedarwell Care Promise, which has been our operating standard since 2010. That means background-checked, uniformed technicians, shoe covers and drop cloths on every visit, a photo of the clean-up before we leave, and a written price before any work starts. We answer the phone with a live person 24/7, because when a window won’t close in a Schertz thunderstorm, you don’t want to leave a voicemail. Our 365-Day Done Right Promise covers the work: if it’s not done right, we make it right.

Common ES Windows Windows & Doors Problems We Solve in Schertz

• Warped or bowed aluminum frames from prolonged sun exposure. Schertz sees long stretches of 100°F days with intense UV, and older ES Windows Aluminum Single Hung frames from the 1960s and 70s soak up that heat year after year. The aluminum bows, the sash binds, and the window won’t seal. We can often straighten and realign the frame, replace the weatherstripping, and restore a tight close without swapping the whole unit.
• Failed or compressed wool pile weatherstripping causing air leaks. The original wool pile in older ES Windows compresses flat over time, especially in the heat. You feel the draft around the sash, and your AC runs harder than it should. We replace the wool pile with OEM-grade material and adjust the sash so it seats correctly.
• Worn or broken roller assemblies in horizontal roller windows. ES Windows Horizontal Roller Series windows take a beating in Schertz, where dust and heat work their way into the roller tracks. The rollers wear down, the window gets stiff, and eventually it derails. We stock heavy-duty replacement rollers locally and can usually fix this in one visit.
• Cracked or fogged insulated glass units from hail impact or failed seals. Schertz gets periodic severe thunderstorms and hail, and the temperature swings from 100°F summers to cold winter mornings stress the seals on double-pane ES Windows units. When the seal fails, the glass fogs. We replace the insulated glass unit itself, not the whole window.
• Single hung windows that won’t stay up. The block-and-tackle balances or spiral balances in older ES Windows Single Hung Series windows wear out, and the sash drops when you try to open it. We replace the balance system, re-tension it, and the window stays put again.

If any of these problems sounds familiar in your Schertz home, call (325) 420-4173 and we’ll diagnose it over the phone or schedule a free estimate.

ES Windows Service in Schertz: What Local Conditions Mean for Your Equipment

Here’s the thing about Schertz that changes how we approach ES Windows service. The original 1960s neighborhoods near Main Street and FM 78 are full of sun-baked ES Windows aluminum frames that have warped so badly they no longer seal, and that’s a problem you won’t find in newer San Antonio suburbs like Cibolo or Universal City, where the housing stock runs heavily toward vinyl. The old Main Street core was built when windows were single-pane and aluminum was the default material. Sixty years of South Texas sun later, those frames have expanded and contracted thousands of times. The aluminum bows outward in the middle, the sash loses contact with the weatherstripping, and the air conditioning bill climbs. In the original town core, you can spot these windows from the street: the glass sits slightly crooked in the frame, and the sash doesn’t quite meet the jamb. It’s not a manufacturing defect. It’s physics. And in most cases, it’s repairable with frame realignment and new weatherstripping, which is exactly what our independent ES Windows service call covers.

ES Windows Models & Products We Service in Schertz

We service the full ES Windows lineup: the Aluminum Single Hung Series, the Horizontal Roller Series, the Casement Series, and the Fixed/Picture Window Series. That covers most of the ES Windows inventory you’ll find in Schertz, from the original aluminum units in 1960s ranch homes to the impact-rated single hungs and horizontal rollers installed in newer subdivisions. Our parts approach is straightforward: we use OEM-grade ES Windows parts when a like-for-like match matters, and high-quality aftermarket parts when they deliver equal durability for less. We stock common rollers, wool pile weatherstripping, balances, and insulated glass units locally so Schertz turnarounds stay fast. If your frame is still square and the glass is intact, we repair it. If it’s not, we’ll show you why.

FAQs – ES Windows Windows & Doors in Schertz

Why do my ES Windows aluminum frames warp in Schertz and can they be fixed?

Schertz’s long, hot summers push exterior temperatures past 100°F, and aluminum expands significantly in that heat. Over decades, that repeated expansion and contraction bows the frame, so the sash no longer seats against the weatherstripping. In most cases we can fix this by realigning the frame, replacing the weatherstripping, and adjusting the sash, without replacing the whole window. Call (325) 420-4173 for an exact assessment.

Are ES Windows horizontal roller windows worth repairing, or should I replace them?

They’re usually worth repairing. The most common failure is a worn roller assembly, which we can replace in a single visit for a fraction of the cost of a new window. If the frame is square and the glass is intact, we’ll repair it. If the frame is bowed beyond realignment or the glass is compromised, we’ll tell you straight and show you the replacement numbers.

Can you make my old ES Windows more energy efficient without replacing the whole window?

Yes. We can replace the weatherstripping, realign the sashes so they seal tightly, and install new insulated glass units in the existing frames if the glass is single-pane or the seals have failed. That combination goes a long way in a Schertz summer. Call (325) 420-4173 and we’ll walk you through the options.

Do you service ES Windows in the older neighborhoods of Schertz near Main Street and FM 78?

Yes. We work throughout the original town core, including homes near Main Street and FM 78, where the 1960s and 70s aluminum ES Windows frames are the most common calls we get. We know the exact warping and weatherstripping patterns those homes have.

What’s your process for repairing an ES Windows single hung that won’t stay up?

We inspect the balance system first, which is usually the block-and-tackle or spiral balance that has worn out. We replace it with an OEM-grade or heavy-duty aftermarket balance, re-tension it, and test the sash through its full travel. Most single hung repairs are done in under an hour. Call (325) 420-4173 for a free estimate.

Last summer our crew was called to a 1970s ranch home off Borgfeld Road in Schertz where the homeowner’s ES Windows horizontal rollers had sun-warped so badly they wouldn’t stay in their tracks. We replaced the worn roller assemblies with heavy-duty aftermarket rollers, realigned the frames, and the drafts stopped. The customer avoided a full replacement and saw the difference on the next cooling bill. Keith Yamada and the crew would be glad to do the same for your home with Window Installation in Schertz. A well-fitted window does its work quietly, you only notice it when the room finally feels right.
