Antioch's housing stock spans 8% pre-1960, 22% 1960-1979, 25% 1980-1999. Architectural styles range from 1970s-80s ranch-style tract homes in older neighborhoods to 2000s-2020s two-story stucco production homes in Lone Tree. Each era and style presents different windows requirements — from material compatibility to structural considerations. Our crews know what to expect before they arrive on site.
Antioch experiences extreme Central Valley-influenced summers with temperatures regularly exceeding 100 degrees, creating significant thermal stress on building materials. Energy-efficient windows with Low-E coatings and proper SHGC ratings are essential for maintaining comfortable indoor temperatures and managing cooling costs in Antioch.
The housing stock in Antioch spans from 1970s-era subdivisions near downtown to newer master-planned communities in the eastern hills, with median home prices around $620,000. Many of these homes retain original single-pane aluminum windows that are inefficient and drafty. Modern dual-pane replacements typically reduce energy costs by 15-25%.

I scheduled to have someone come give me an estimate for all new windows in our 1950s home with not so great Remodeling work by previous owners. Alex Li promptly met with us & his crew throughout the entire process. They were always on time to work, left our home clean of debris & spectacular new JeldWin windows. Helped me with getting Financing as well...Just all around a great experience & highly recommend!

I recently hired Hamilton Exteriors to replace my siding and windows, and they did a fantastic job. Their team was punctual, polite, and paid close attention to detail. The siding looks seamless, and the new windows have made a noticeable difference in both appearance and energy efficiency. Communication was always clear, and they finished on time and within budget. I’m very happy with their work and would definitely recommend them.
