A great way to add to the beauty of your San Francisco Bay Area home while reducing heating and cooling costs is to replace your old windows. 21st Century Home Improvement offers all styles of wood, wood clad, aluminum, and vinyl windows from a variety of manufacturers including Milgard, Marvin, Anderson, CertainTeed, Anlin and others. Our representatives can help you sort through the nearly endless choices based on type of window, manufacturer, and window options.

Our window department reviews all window replacement options with the customer, measures for an accurate custom fit, and orders the windows from the manufacturer. Once your new windows arrive, we carefully remove the old windows and install your new windows with the same craftsmanship we bring to all of our home improvement services.

Many of our window projects involve replacing old aluminum windows with new vinyl windows. This is due in large part to the benefits of vinyl windows. Vinyl windows never need to be painted, are easy to clean, do not swell and jam due to moisture, and provide outstanding insulation. Another benefit of vinyl windows is that they are ‘retrofit’ windows, meaning that they can be installed without removing your old window frames and without disturbing the exterior stucco or siding of your home.
