ES Windows Construction in Katy, TX | Penhallow Remodeling Houston
We’re Penhallow Remodeling Houston, your Katy General Contractor, and we provide independent ES Windows construction, replacement, and repair across Katy. We’re not manufacturer-affiliated or an authorized dealer, which means we call it straight on whether a sash swap, a full-frame replacement, or a simple roller job is the right move for your home. That independence matters here, where two homes five miles apart can face completely different HOA rules and soil conditions. Call (254) 527-5340 for a written estimate on any ES Windows job.
Why Katy Residents Choose Us for ES Windows Service
We’ve worked on ES Windows in enough Katy homes to know the difference between a Cinco Ranch architectural-review replacement and an Old Katy “just make it work” retrofit. Trevor Nash, our owner, came up the hard way: construction technology at Los Angeles Trade-Technical College, then years on tract homes and gut renovations before he started serving Houston. He writes estimates the way he talks: line by line, with the number in front of you before you sign. Our crews stock OEM ES Windows balances, weatherstripping, and glazing gaskets for the 3500, 4500, 5500, and 7500 series, plus quality aftermarket parts for older units where OEM has been discontinued. That means fewer return trips and a faster fix for Katy homeowners. We also install full replacements and impact-rated windows, and we handle the roof repair work that often goes hand-in-hand with window leaks around flashing and eaves.

Common ES Windows Construction Problems We Solve in Katy
- Failed rubber glazing gaskets. South-facing ES Windows in Katy take brutal afternoon heat and UV, and after enough summers the rubber hardens, shrinks, and lets air move through the glass. You see condensation between panes, or feel a draft at the edges. We replace the gaskets with OEM parts when the window series is still in production.
- Sticking single-hung sashes. The 3500 Series single-hung is common in Katy’s master-planned communities, and this area’s expansive clay soil doesn’t stay put. As moisture levels shift season to season, the slab moves enough to torque window openings slightly. A sash that slid fine in March binds by August. We re-square the frame and rebalance the sash instead of forcing it.
- Worn slider rollers. Katy’s constant construction and pollen seasons are hard on horizontal sliders. Dust and grit work into the roller assemblies on 4500 Series units, and after a few years you’re leaning your body weight into the window to move it. We clean or replace the rollers, and realign the track.
- Aluminum frame corrosion near water features. Homes around Cinco Ranch retention ponds, or with sprinklers that overspray onto the windows, show accelerated frame pitting and corrosion at the sill. We assess whether it’s a surface issue or structural. If the frame is compromised, we recommend replacement rather than a patch.
- Water intrusion at the sill during heavy storms. Spring thunderstorms in Katy hit hard, and when weep hole covers are clogged with silt or corroded shut, water backs up and finds the drywall beneath your window. We clear the weep channels, replace the covers, and inspect the exterior seal before the next storm cycle arrives.
ES Windows Service in Katy: What Local Conditions Mean for Your Equipment
Here’s the thing about Katy that no generic window page will tell you: in Cinco Ranch, the HOA architectural review requires that any replacement windows match the original builder specifications, which in a large share of those homes means ES Windows, down to the frame color and grid pattern. Drive five miles east into Old Katy and there’s no such restriction, so a homeowner there can swap to a different brand, change the style, or go with fewer grids entirely. That split means our sourcing and installation approach changes depending on which side of the Grand Parkway you’re on, and it’s exactly why we carry OEM glazing, balances, and hardware for the four most common ES Windows residential series. We’ve done full-frame replacements in Cinco Ranch that required HOA pre-approval, and we’ve done sash-only repairs in Old Katy that took an afternoon. Knowing which set of rules applies before we show up keeps the job moving and keeps you out of HOA violation notices.
ES Windows Models & Products We Service in Katy
We service and install across the ES Windows residential lineup: the 7500 Series aluminum fixed window, the 3500 Series single-hung, the 4500 Series horizontal slider, and the 5500 Series casement. For critical components like balances and weatherstripping, we use ES Windows OEM parts when they’re available. For older models where the factory part is discontinued, we source quality aftermarket rollers, glazing, and hardware that match the original specs. If the frame has widespread corrosion or chronic seal failure, we’ll tell you a full replacement is the cheaper long-term move, not another patch job. We also install impact-rated windows for Katy homeowners who want storm protection beyond the standard builder-grade glass, and we handle the roof repair work that often accompanies window leaks in older homes near Old Katy. For full ES Windows sales & service, we’re your independent local option.

FAQs – ES Windows Construction in Katy
In most cases we can replace just the insulated glass unit (the IG) and keep your existing frame, as long as the aluminum frame itself isn’t corroded or out of square. The 7500 Series is a fixed window, so the glass replacement is straightforward unless the frame has been twisted by clay soil movement. We’ll inspect the opening before we quote either path. Call (254) 527-5340 and we’ll take a look.
Usually no. Hard-to-open 4500 Series sliders in Katy are almost always a roller or track problem, not a whole-window problem. We clean or replace the roller assemblies, realign the track, and often restore the window to working order without replacing a single pane. If the frame itself has shifted significantly from soil movement, we’ll square it before putting anything back together.
In most cases yes, because we match the original builder specs: same ES Windows series, same frame color, same grid configuration, same glass package. Cinco Ranch’s architectural review committee wants replacements that look like they came with the house, and that’s exactly how we quote them. We’ll help you prepare the submission so it moves through review without a ping-pong of rejections.
Yes, this is one of the most common calls we get between March and June. Spring thunderstorms in Katy dump water fast, and when weep hole covers are clogged or the exterior seal has failed, the water finds its way inside. We clear the weep channels, replace the covers, and reseal the exterior, then check the flashing and surrounding stucco or brick for other entry points. If roof repair at the eave or flashing is part of the problem, we handle that too. Call (254) 527-5340 for a storm-leak inspection.
Absolutely. In Old Katy you have the freedom to match your existing windows or change them up entirely, and we’ll walk you through what works in a two-story brick ranch versus a mid-century frame home. We can spec ES Windows to match the rest of the house, or help you choose a different configuration if you’re adding on and want more glass or a different operator style. We also do Bathroom Remodeling - Katy homeowners trust for quality work. Estimates are free, and the quote is written before any work starts.
