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

Born out of personal protest, Upright Windows LLC was founded on the principles of honesty and integrity. We believe homeowners deserve a reasonably priced option for windows without compromising on quality.

  Upright windows came to check out windows after they leaked during a recent hurricane and found that the vault around many of them had deteriorated.   They cleaned and recaulked all windows in a timely manner for a good price.   They checked our son’s home and our office as well and found them not to need anything.    They are honest, dependable and reasonably priced.

Improved Energy Efficiency

Single-pane windows provide minimal insulation, allowing heat to enter during summer and escape during winter. Upgrade to our double-pane windows with Cardinal 366 LoE coating is a must.

Increased Comfort

Upgraded windows help maintain a stable indoor temperature, eliminating drafts that contribute to hot and cold zones common with single-pane windows. Additionally, double pane windows reduce condensation

Noise Reduction

Double-pane windows provide exceptional soundproofing. Customers often see a significant reduction in outside noise, including common disturbances such as barking dogs, noisy neighbors, and loud children playing outside. Double-pane windows are an ideal solution for enhancing peace and quiet.

Enhanced UV Protection

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

Increased Home Value

Energy-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.
