Do You Need to Replace Your Windows?
Even the highest-quality window materials have a limited lifespan, and we recommend that homeowners in the area proactively replace their windows based on the expected product lifespan. Old windows often become inefficient before more visible issues arise. Keep an eye out for drafts and excess moisture that can’t be resolved with new weatherstripping. It’s also a good idea to replace windows with non-superficial damage to the glass or frame, those that are difficult to open and close, or those that are no longer secure.

Enhance Your Home with Energy-Efficient Windows
The Window Source of Houston offers an extensive range of energy-efficient windows, many of which are ENERGY STAR certified. Optimal energy efficiency can be achieved through various window materials, including vinyl and composite, as well as window features like multiple glass panes and Low-E glass coatings.

The Window Source of Houston stands out as the wise choice for your window replacement for several reasons, starting with our years of experience. We’ve earned the trust of homeowners through our expertise, large vendor network, and most importantly, our customer-centric approach. We also provide our customers with peace of mind with an industry-leading lifetime warranty.

Choose the Right Windows for Your Home
Natural light and energy efficiency are popular selling points for homes, and the right windows can provide a significant return on investment. When building or remodeling, select the window types that best meet your lighting, function, and budget needs. We install replacement windows such as single-hung, double-hung, bay, bow, picture, casement, slider, awning, and garden windows. We frequently work with vinyl and composite window materials, as well as popular brands manufactured in the United States.

Vinyl Windows
Vinyl is the most popular material choice for replacement windows because it is inexpensive relative to wood and requires practically no maintenance.

Composite Windows
Composite windows provide an aesthetically pleasing, energy-saving, and low-maintenance choice that significantly elevates the overall value of a home.

Virtually Any Style Window Available
Both vinyl and composite window materials are suitable for all window styles commonly used in residential applications in this region. This includes the prevalent double– and single-hung windows, as well as custom windows and specialty shapes. Bay, bow, casement, sliding, picture, awning, garden, impact, and egress windows are also available options.

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.”
