Window Company in San Clemente, CA
Most San Clemente window and door projects run between $850 and $3,200 per opening, with final cost driven by the custom arched or non-standard openings common in the city’s 1920s Spanish Colonial stock and the marine-grade materials needed for coastal salt exposure. We’re Lightwell Windows & Doors, the local Cedarwell company serving San Clemente from our Los Angeles office, and we carry eight manufacturer brands so we can fabricate units that actually fit your home’s original openings rather than forcing standard rectangles into historic curves.

Why San Clemente Homes Are Different
San Clemente was master-planned in 1925 as a “Spanish Village by the Sea,” which means a disproportionate share of the housing stock features arched window openings, custom casement windows, and thick stucco surrounds that require non-standard, custom-fabricated units. The original steel casement frames in homes near the historic downtown and Avenida del Mar corridor are typically corroded past repair, and their openings don’t match any standard window catalog.
The westward-facing Pacific bluff exposure delivers constant salt-laden wind directly at window frames and door hardware. San Clemente sits on coastal bluffs where the persistent marine layer subjects glazing seals and hardware to near-continuous salt-moisture stress without the UV drying cycles inland cities get. This accelerates seal failure and frame oxidation on west- and south-facing elevations, making marine-grade fiberglass or aluminum-clad wood a genuinely functional decision, not a cosmetic upgrade, for any property within a half-mile of the shoreline. Contractors who arrive with standard rectangular window orders for historic neighborhoods near the pier routinely face costly re-orders or field modifications; San Clemente-experienced installers price the custom fabrication in from the start.
Our Main San Clemente Services
San Clemente homeowners call us most often for window replacement in aging Spanish Colonial and mid-century homes, and for door installation that stands up to coastal salt exposure. Each service has its own dedicated San Clemente page with full pricing and details.
Window Replacement in San Clemente
We replace corroded steel casement windows, failed aluminum units, and fogged dual-pane glass throughout San Clemente’s varied housing stock, from 1920s Spanish Colonial Revival originals to hillside developments. The marine layer here means we specify marine-grade fiberglass or aluminum-clad wood for west-facing elevations rather than standard aluminum that will oxidize within seasons. Every replacement includes custom measurement for arched or non-rectangular openings common near downtown and the pier. Window Replacement in San Clemente.

Window Installation in San Clemente
New window installation in San Clemente demands rough-opening verification before ordering, especially in historic neighborhoods where original framing followed non-standard radii. We verify every opening ourselves rather than relying on original plans, and we specify coastal-rated flashing and sealants that flex through salt-air temperature cycles. Our crews work with low-dust methods and quiet tools during family hours, and we explain the written price before touching anything. Window Installation in San Clemente.

Door Installation in San Clemente
Door installation here means selecting hardware and frame materials that survive constant salt spray, particularly for west-facing entries on coastal bluff properties. We install fiberglass and steel entry systems from Therma-Tru and coastal-rated sliding and French door configurations that maintain seal integrity through marine-layer humidity cycles. Every installation includes pet-safe sealants where alternatives exist and full cleanup with drop cloths and shoe covers. Door Installation in San Clemente.

What San Clemente Customers Say
"They replaced a big foggy picture window. Careful with the furniture, laid down protection, and left no mess at all. Calm and respectful crew, and the view is clear again."
- Teresa Okafor"Replaced six windows. The crew laid runners through the house and vacuumed each room as they finished. With a crawling baby, that no mess thing meant a lot. Windows are gorgeous."
- Rosalind Kemp"Lovely windows and a tidy install. One window came in a couple weeks late from the factory, so that opening finished after the others. They kept me posted and the rest was spotless."
- Mia Donnelly
