Patio doors in San Marcos, CA.
Patio doors for San Marcos homes, done by insured San Diego County window crews. Almost every San Diego home has at least one patio door, and the original sliding glass doors from the 1970s and 1980s are among the most common window-adjacent projects we see. We connect homeowners with insured local crews that replace failing patio sliders and add new patio door openings, with insulated dual-pane glass, corrosion-resistant frames, and hardware that holds up to daily use..
Why is patio doors different in North County Inland San Diego?
In Escondido, Vista, and San Marcos, patio sliders are a standard feature on 1970s and 1980s ranch-style homes, and many of those original aluminum sliders are at or past the end of their useful life. Replacing an aging aluminum slider with a vinyl dual-pane unit reduces solar heat gain in summer, a real benefit in inland San Diego where afternoon temperatures on a rear patio can push past 95 degrees and radiate back into the house through an uncoated single-pane door. The vetted crews we refer install low-profile tracks that don't create a tripping hazard at the threshold, which is a practical consideration for families with children or older adults. ADU builders in this region increasingly specify patio sliders for the rear access of a detached ADU, and the crews we refer can size and install those units to the ADU's specific rough opening.

What is the difference between a sliding patio door and a French door?
A sliding patio door has panels that roll horizontally on a track. A French door (or hinged patio door) has panels that swing in or out on hinges. Sliding doors take up no floor space when opened and work well on patios with limited clearance. French doors have better air sealing because they compress against a continuous weatherstrip when closed. The choice often comes down to clearance space and personal preference.
