Window installers, dealers and manufacturers serving Houston, TX appear on this page as company profiles. GlassBase is an independent platform: it lists companies and calculates window performance, and it does not sell or install windows itself.
Choosing a company: profile, certifications, quotes
Every profile includes an about section, stats, certifications and contact details. A practical sequence for a window replacement project in Houston looks like this:
- Filter the list by replacement or by a brand you are considering
- Open several profiles and compare what each company describes about its work and certifications
- Run the energy calculator for your ZIP code and save the PDF report
- Send quote requests through the profiles of the companies you shortlisted
Other Texas cities have their own pages, including Dallas and San Antonio.
Energy savings for Houston ZIP codes
The window energy efficiency calculator uses NREL TMY3 climate data for your ZIP code to estimate whole-window U-factor, SHGC and heating and cooling savings, and it produces a PDF report. Comparing that estimate with the U-factor and SHGC of the windows each company proposes shows how the options differ before any contract is signed.
