California Thermal Windows

California Thermal Windows is a Window installation service in San Francisco focused on energy-efficient replacements and custom-fit solutions for local homes and condos. Book an in-home assessment to compare double-pane Low-E glass, frame materials (vinyl, aluminum, fiberglass), and whether retrofit or full-frame installation makes the most sense for your project. Ask for an itemized quote that spells out measurements, permitting, disposal/cleanup, and separate warranties for products and labor. If you need better comfort or quiet, request STC-rated and solar-control glass options, and confirm timelines, financing, and any available utility rebates before you commit.
