Our Satisfied Customers

We used Texas Window Store to put in 3 new windows during a home remodel. They communicated well, installed the windows professionally and quickly and we're thrilled with how everything turned out. The windows look great and is one of the things people comment on the most when seeing our remodeled house for the first time. Added bonus, they're energy efficient!

James' crew was on time, conscientious, and customer-focused. I wish our other contractors were as professiona! They highlighted any installation issues, gave us options, and executed right away. Many friends and neighbors complimented us on the results. We have 30% more light, 20% less exterior noise, and 20-30% lower electricity bills. Would definitely recommend!

Love my windows! I chose this company out of many because they were the most personable and only company that didn’t make me feel pressured. They were great with communicating throughout the whole process! My 1954 house got new windows and they are gorgeous!

Jesse and his team were fantastic. After getting several quotes for windows, we decided to work with Texas Window Store because they are 1) independent, 2) extremely knowledgeable, 3) fairly priced. Our home looks amazing and I’m very appreciative for the easy process and excellent communication.

I had gotten a few quotes for windows and Texas Window Store had a very competitive price for my project. Not only did I have replacement windows put in, I had a custom window put where there was no window, which is bit more complicated. All the windows turned out beautiful and the installation process was clean, efficient and professional. Thanks guys!

I recently had Texas Window Store replace a few old single pane windows at my house after my dog broke one of them. Jesse was quick to send me a quote and was able to have the windows in half the time of other companies I spoke with, and for a great price too! Once my windows arrived they were quick to schedule the install crew and had everything completed the same day. Our new windows look great!

Frequently Asked Questions

Are fiberglass windows a good choice for Texas homes?

Yes! Fiberglass replacement windows are one of the best choices for Texas homeowners due to their high durability, energy efficiency, and resistance to extreme weather. Unlike wood or vinyl, fiberglass does not warp in hot Texas summers or expand/contract with sudden temperature changes, making it perfect for areas like Austin, Houston, and Dallas.

How do fiberglass windows compare to vinyl windows in Texas?

While vinyl replacement windows are cost-effective and energy-efficient, fiberglass windows offer greater strength, longevity, and insulation. Texas homeowners who experience severe heat, storms, or fluctuating temperatures benefit from fiberglass because it outlasts vinyl by 20+ years and provides better thermal performance.

What is the average cost of fiberglass windows in Texas?

The price of fiberglass windows in Texas typically ranges from $700 to $1,500 per window, depending on size, style, and energy-efficient upgrades. Though they cost more upfront than vinyl, fiberglass windows have a 50+ year lifespan, making them a long-term investment for homeowners in cities like Dallas, Austin, and San Antonio.

Are fiberglass windows energy-efficient for Texas weather?

Absolutely! Fiberglass windows provide excellent insulation, reducing heat gain in summer and heat loss in winter. With Low-E glass, argon gas fills, and airtight seals, fiberglass windows lower energy bills by up to 30% (source), making them an ideal option for Texas’ hot climate.

Do fiberglass windows require a lot of maintenance?

Not at all! Unlike wood windows, which require regular sanding and painting, fiberglass windows resist fading, warping, and cracking. They are low-maintenance, needing only occasional cleaning with soap and water to maintain their appearance.

Can fiberglass windows withstand Texas storms and hurricanes?

Yes! Fiberglass windows are highly impact-resistant, making them a smart choice for homeowners in coastal Texas areas like Galveston, Corpus Christi, and Houston. When paired with impact-resistant glass, fiberglass windows can withstand strong winds, heavy rain, and flying debris.
