Why National City homeowners choose 5 IN 1 for windows & doors
Windows & Doors in 5 National City neighborhoods
National City is one of the oldest cities in San Diego County (incorporated 1887) with a housing stock that goes back to the early 1900s. Many craftsman bungalows, mid-century post-and-beam homes, and 1950s ranchers. Remodels here often involve older plumbing (galvanized supply lines, cast-iron drains) that should be addressed when walls are open. Permits go through the City of National City Engineering and Building Department.
We have remodeled National City homes since 1987. The Carrasco family runs every job site, the same in-house crew handles your project from rough-in to final walk, and we pull every permit in your name.

Windows & Doors in National City: frequently asked questions
How much does window replacement cost in National City?+
In National City, replacement windows run $600 to $1,200 each installed, and a whole-home replacement of 10 to 15 windows runs $8,000 to $20,000. Entry doors run $1,200 to $3,500 and patio doors $2,000 to $5,000. We quote per opening in writing.
How long does window replacement take?+
Most window jobs finish in 1 to 3 days. A single door is a same-day install. Full-frame replacements that involve stucco or siding repair add a day or two for the exterior patch to cure.
Do I need a permit to replace windows in National City?+
A like-for-like retrofit usually does not need a permit in National City. If you are changing the opening size, adding egress for a bedroom, or doing a full-frame replacement, a permit is required. We handle it either way.
Are new windows worth it in San Diego's climate?+
Yes, mostly for comfort and noise. Dual-pane low-E windows cut afternoon heat gain, block UV that fades floors and furniture, and quiet street noise. The energy savings are real but modest in our mild climate, so we set honest expectations.
What windows hold up best in National City?+
In coastal National City areas, we recommend vinyl or fiberglass frames and corrosion-resistant hardware because salt air is hard on aluminum. Inland, aluminum-clad and vinyl both hold up well. We match the frame to your exposure and budget.
