Orange County Window Replacement
Window Replacement in Santa Ana, CA
Santa Ana has some of Orange County's oldest residential housing stock, with many homes built between 1940 and 1965. This era's original steel or aluminum single-pane windows are now 60–80 years old — well past any reasonable service life. Homeowners in Santa Ana often find that their windows no longer seal, lock, or operate as designed.
Tesla Windows serves Santa Ana homeowners with triple-pane, ENERGY STAR® certified vinyl windows — installed in a single day, with a limited double-lifetime transferable warranty.
