No St. Louis home is alike and every homeowner has their own unique style and design preference. During your free in-home consultation, our replacement window consultant will walk you through your window style options and colors. They’ll also review our current promotions, calculate your estimated monthly payment and energy bill savings, and determine the best financing options for your project so you can get the best solution for your needs.
St. Louis’s climate can be challenging and your home’s windows are an important barrier. Our Energy Star® certified windows are built using our specialized Comfort 365 Window® Glass, which incorporates low emissivity (Low-E) glass technology and superior insulation for better temperature control saving you money each and every month. According to the U.S. Department of Energy, heat gain and heat loss through windows are responsible for 25%–30% of residential heating and cooling energy use.
Our Comfort 365 low-E glass technology and argon gas insulation keeps your home warm in the winter and cool in the summer.
Gaps, weak seals, and other installation issues can affect the energy-efficiency of your windows. This is why Champion Windows takes the time to get exact measurements and follows a thorough step-by-step installation process, ensuring a weatherproof fit every time. And don’t worry, our installation technicians clean up completely before leaving for a stress free experience.
