Orange County Window Replacement
Window Replacement in Anaheim, CA
Anaheim's residential neighborhoods were largely built between 1950 and 1975. Homes of that era typically have original single-pane aluminum or steel windows — the least efficient glass type available, with U-Factors around 1.10. Many Anaheim homeowners are replacing entire homes' worth of windows in one project.
Tesla Windows serves Anaheim homeowners with triple-pane, ENERGY STAR® certified vinyl windows — installed in a single day, with a 25-year transferable warranty.

Frequently Asked Questions — Anaheim Window Replacement
Do I need a permit to replace windows in Anaheim?
Replacing windows in the same opening size typically does not require a permit in Anaheim. If structural changes are involved, a permit is needed. Tesla Windows handles permit applications in-house when required.

Most Anaheim single-family homes have 10–18 windows. Our crew typically completes installation in one day, arriving in the morning and finishing by late afternoon.
Can you replace windows in older Anaheim homes with plaster walls?
Yes. Our crews are experienced with the 1950s–1970s construction common in Anaheim, including lath-and-plaster interiors and older window openings that may need minor framing adjustments.
