Replacement & New-Construction Windows in Houston, TX
A Houston-based window manufacturer — factory-direct pricing on energy-efficient windows built for the Gulf Coast climate.
Windows built in Houston, for Houston
Reliable Windows isn't a dealer or a re-seller — we're a window manufacturer based right here in Houston. Every window we sell is built to order at our facility on Calle Lozano Drive using the German-engineered Reliable 5700 Series profile system. For Houston homeowners, builders, and property managers, that means factory-direct pricing, faster turnaround than ordering from out of state, and windows engineered specifically for what Houston weather throws at them.
And Houston weather is demanding. Triple-digit summers, relentless Gulf humidity, sudden thunderstorms, and the occasional hurricane all put serious stress on a home's windows. Builder-grade windows — the most economical option a developer could install — simply weren't made to handle decades of it. Foggy glass, drafts you can feel, and steadily climbing energy bills are the result.
Houston's housing is as varied as the city itself — historic bungalows in The Heights and Montrose, mid-century ranch homes in Meyerland and Oak Forest, sprawling new construction on the suburban edges, and everything in between. We manufacture windows for all of it, in standard and fully custom sizes, and we serve every Houston neighborhood and ZIP code.
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 Houston homes
Houston homes use a mix of window styles depending on age and architecture. Single hung windows are the most common across the city, while sliders and picture windows are popular in mid-century and contemporary homes.
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.
