COLORADO'S EXTREME CLIMATE DAMAGES WINDOWS

SELECTING THE RIGHT PRODUCT IS KEY

WARM IN THE WINTER, COOL IN THE SUMMER

Colorado’s abundance of sunshine, extreme weather patterns, and sudden changes in temperature are tough on windows.

Our elevation doesn’t help. Sustained sun exposure at higher elevations exacerbates the conditions that cause windows to deteriorate.

Replacement windows are not the standard windows your builder installed when the house was built.

We discuss your options and guide you through the selection process to ensure you understand the importance of investing in the right replacement product for your situation.

Today’s high-performing, energy-efficient replacement windows create a more comfortable home, with even temperatures and no drafty corners.

Energy-efficient windows are third-party certified to ensure their performance, and they typically result in lower utility bills.

DID YOU KNOW...?

According to HomeAdvisor, 25% of the costs for heating and cooling your home comes from the energy lost through your windows.

Carefully considering which type of window is right for your home could save you thousands of dollars in energy costs, while increasing the resale value of your home.

Also, independent market studies have noted that 65% of service-related issues involving prematurely failed windows are related to improper installation. This is due to:

  • Shortcuts during the installation of new or replacement windows
  • Low-cost faulty sealants
  • Improper flashing methods

The vinyl windows in our townhouse were 20 years old and showing signs of their age. We contacted several companies for bids. Some of the presentations were really long. We really appreciated Ted’s selling style of letting the product speak for itself. He didn’t waste our time. His pitch was informative and very low pressure. I’m so happy we chose to go with Brent and his team.

I dreaded the installation process and the cleanup afterwards. My husband was home when the windows were installed. I couldn’t believe it when I got home from work and the windows were in and there was no mess! I would not have known the installers had come if it weren’t for our beautiful new windows. The company is very responsive and workmanship was outstanding. I highly recommend Nex-Gen Home Exteriors for window replacements!
