Palo Alto, CA's Highest-Rated Window Installers on Google
We don't have license data for window and glazing businesses in Palo Alto, CA the way we do for some other cities on this site. This page leans on Google Maps instead: 8 businesses, ranked by rating weighted against how many people reviewed them. A strong Google rating still isn't the same thing as a license on file, so ask to see one before you sign anything.

What Palo Alto's climate means for your window spec
Palo Alto sits in IECC climate zone 3C, the starting point for any code-minimum window performance here.
ENERGY STAR places Santa Clara County in its South-Central zone for window certification.
Normal temperatures run 48°F in January and 68°F in July, so the glass package worth paying for in Palo Alto isn't the same one that pencils out two zones over.
