Vinyl Replacement Windows in Katy, TX
Energy-efficient, Houston-built windows for Katy's master-planned communities.
Replacement windows for Katy's growing neighborhoods
Katy has been one of the fastest-growing communities in the Houston metro for more than two decades. Master-planned neighborhoods like Cinco Ranch, Cross Creek Ranch, Seven Meadows, and Grand Lakes filled with family homes built through the 1990s, 2000s, and 2010s — and many of those homes are now reaching the age where the original builder-grade windows are starting to fail.
If your Katy home has windows with foggy or cloudy glass, drafts near the frame, sashes that stick, or summer electric bills that keep creeping up, the windows are usually a big part of the problem. Builders use the most economical windows they can to hit a price point — they were never meant to be the long-term answer. Reliable Windows manufactures the replacement: Reliable 5700 Series vinyl windows, built to order in Houston and sized to fit your exact openings.
Katy homes tend to be larger two-story family homes, which means a lot of window area — and a lot of surface for the Texas sun to heat up. Upgrading to insulated, Low-E double-pane windows makes a real, measurable difference on cooling costs, and with four color options there's a finish that keeps your HOA happy.
Why work with a local manufacturer
A true manufacturer, not a reseller
We build every window to order in our Houston facility. Buying factory-direct means no middleman markup and no long waits for out-of-state shipments.
Engineered for the Texas climate
The Reliable 5700 Series profile with insulated, Low-E double-pane glass is built for triple-digit heat, Gulf humidity, and storm season — a 0.24 U-Value and an R-PG50 rating.
Custom sizing for any opening
Standard sizes or fully custom — including arches, geometric shapes, and combination units. Your windows are cut to your home, not the other way around.
Backed by a 10-year limited warranty
Every window is covered by a 10-year limited warranty and four durable color options — White, Almond, Bronze/White, and Black/White.
Window styles for Katy homes
Katy's two-story family homes most often use single hung windows, with sliders along rear walls and picture windows in living areas to bring in light.
Reliable 5700 Single Hung
Our most popular style — a fixed top sash with an operable bottom sash. Clean, classic, and efficient.
Reliable 5700 Slider
Horizontal-opening windows ideal for wide openings and rooms where an outward swing is not practical.
Picture Windows
Fixed windows that maximize natural light and views with the slimmest possible sightlines.
Specialty & Custom Shapes
Arches, c-tops, trapezoids, and combination units built to match distinctive architecture.
