Composite Windows For Your Home
Composite windows represent a visually appealing, energy-efficient, and low-maintenance window solution that significantly enhances a home’s value. At The Window Source of Houston, we offer a diverse range of premium composite-framed windows from well-established and trusted brands. Our dedicated team will assist you in selecting the perfect replacement windows for your residence and provide expert installation, accompanied by a complimentary warranty covering all window replacement services and workmanship.

Is it Time for a Window Replacement?
When contemplating an investment in composite windows, the foremost factor to consider is their age. While updating your windows is an excellent idea if they appear outdated, we recommend replacing them before they exceed their anticipated lifespan, as this can lead to diminished performance or potential moisture intrusion. Windows may wear out prematurely, making it prudent to replace them if you’re encountering drafts that compromise home comfort, heating, and cooling efficiency. Difficulty in opening, closing, or securing windows, as well as non-superficial damage to the glass or frame, are also compelling reasons for replacement.

The Advantages of Composite Windows
Composite windows boast remarkable longevity, with most products offering a lifespan of at least 40 years, some even extending to 65 or 85 years. This means that composite windows tend to deliver a superior total cost of ownership compared to most other window materials. They provide the aesthetic appeal of real wood without the maintenance hassles, resisting fading, rot, and mold. Furthermore, they excel in energy efficiency, noise insulation, and eco-friendliness.

Exceptional Energy Efficiency of Composite Windows
Windows play a pivotal role in your home’s building envelope, and well-performing windows enhance comfort and maintain consistent temperature levels while reducing heating and cooling costs. Composite windows are meticulously engineered to minimize energy transfer and can be equipped with numerous features that further enhance energy efficiency, including multiple panes, Low-E coatings, and warm edge spacers. Many of these windows are ENERGY STAR certified, ensuring high performance.

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.”
