Upright Windows LLC

We are a family owned Energy Efficient Window Replacement Company in Klein, Texas.

In the summer of 2023 the Upright Window brand was born out of personal protest to outrageous replacement window pricing. My first experience consisted of a 2-hour presentation that ended with the sales person quoting me 78 thousand dollars for 29 windows.

I thought he was joking and once I realized he was serious, I felt angry and frustrated. He then went outside, made a phone call to return with the “today only” price of 62 thousand dollars. At that point I was done and asked him to leave. I received several more quotes from large window companies, which yielded the same outcome.

Why We Exist

  I had issues with another company (Glass Doctor) for weeks.  No communication, several delays. I finally cancelled and called Upright Windows.  Our window was fixed within 2 days of calling them, and for $140 less than I was quoted from Glass Doctor.  I can’t recommend Upright Windows enough.  Great customer service, great price, and great product.

  I had a great experience with this window company! Communication was excellent — they kept me updated every step of the way. The turnaround time for a quote was impressively fast; I received it the same day I submitted my request. They came out to replace a window glass and balances, and everything was done efficiently and professionally. Highly recommend their service!

  Upright windows was a gem to find!!  Working with this company was a delight. From the first call I made to order the window, to get the window sized and to follow through with the
installation process, I found a company to be totally professional. Everyone of the employees that I met was kind and very respectful.   I would highly recommend this company if you need a window replaced or the whole house of windows replaced.

Improved Energy Efficiency

Single-pane windows provide minimal insulation, allowing heat to enter during summer and escape during winter. Upgrading to double-pane or triple-pane windows with Low-E glass

Increased Comfort

Upgraded windows help maintain a stable indoor temperature, eliminating drafts and cold spots common with single-pane windows. Double- or triple-pane windows reduce condensation

Noise Reduction

Double-pane or triple-pane windows offer better soundproofing than single-pane windows, reducing outside noise, which is particularly beneficial in urban areas or near highways.

Enhanced UV Protection

Modern windows often include UV-blocking coatings that protect your furnishings, flooring, and artwork from harmful UV rays

Increased Home Value

nergy-efficient windows are a desirable feature for homebuyers. Replacing old single-pane windows can increase your home's resale value

Improved Security

Double-pane or laminated glass options provide better security against break-ins compared to single-pane windows, which are easier to break.

Rebates and Incentives

There are often local, state, or federal incentives and rebates available for upgrading to energy-efficient windows

Reduced Environmental Impact

By reducing the energy needed for heating and cooling, energy-efficient windows contribute to lower greenhouse gas emissions

Better Air Quality

Improved insulation reduces moisture buildup, leading to better indoor air quality and less risk of mold and mildew growth.
