“My husband and I are obsessed with our new windows from The Window Source!! They were delivered in a very short time frame and only took a day to install. Great install crew, very clean, efficient, and paid attention to detail when sealing everything off.”
Houston Casement Window Replacement
If you want big views and bountiful breezes, a casement window is the right choice for you. With an expansive, uninterrupted glass area and top-to-bottom ventilation when cranked open, they are beautiful as well as energy efficient.
Casement windows are best suited for improving the airflow throughout your home. Unlike other windows that open from the top or bottom, casement windows feature an adjustable hinge that allows the window to open from the side at various angles for enhanced ventilation and comfort and they also provide an attractive option that maximizes viewing area.

Benefits of New Casement Windows
Casement windows offer a range of benefits that make them a desirable choice for homeowners. Their design provides excellent ventilation and airflow control. With their side-hinged mechanism, casement windows can be fully opened outward, allowing for maximum fresh air to enter the space. This feature is especially beneficial in areas where cross-ventilation is important. Casement windows also provide unobstructed views and ample natural light due to their expansive glass area. Their single-panel design offers a sleek and modern aesthetic that complements various architectural styles. Casement windows are known for their excellent energy efficiency. When closed, their sashes press tightly against the frame, creating a strong seal that helps prevent air leakage and enhances insulation. With their superior ventilation, aesthetic appeal, and energy-saving properties, casement windows are an excellent choice for homeowners seeking both functionality and style.

How we install your new windows
Each old window comes out with its frame, and the new one is built to the measurements of your opening. Before it goes in, we seal the opening with our Leak Shield system. That means a flashing membrane over the rough opening, butyl tape at every seam and flange, low-expansion foam in the gap between frame and wall, and a final exterior seal.
Leak Shield comes with every installation at no extra cost, and we back every installation we perform with our lifetime Leak Shield Guarantee.
We will never leave the job without ensuring you have the highest quality windows installed properly and your home is left spotless. We take pride in our work and respect your space, aiming to leave behind one of the cleanest job sites you’ve ever seen.

What Houston homeowners say
“I got several quotes, and Jairo was the only one who brought samples and took the time to give us a demonstration. The office stayed in communication with me every step of the way… Edwin’s installation team worked quickly and professionally.”
“Replacing my parents’ original builder-grade windows in their 25+ year old home was one of the best investments they’ve made… They’ve already noticed lower electric bills, less outside noise, and a cooler, more comfortable home that’s much easier to keep at a consistent temperature.”
