AfterWindow Company in Tiburon, CA
Window and door work in Tiburon demands marine-grade specifications you won’t find in inland Marin County. The salt air, wind-driven rain, and three-sided Bay exposure here corrode standard aluminum frames and seize hardware in 10 – 15 years, not the 25+ you’d expect farther from the water. At Lightwell Windows & Doors, we specify fiberglass and aluminum-clad wood frames with multi-point locking systems built for this exact environment, and we put every price in writing before touching anything. Call (562) 478-8017 to schedule your free estimate.
Why Tiburon Homes Are Different
Tiburon’s peninsula geography creates a genuinely harsh microclimate for windows and doors. Along Paradise Drive and the Bay-facing slopes below Lyford Drive, we regularly see original 1960s aluminum picture windows oxidized to chalky white, with casement hardware completely seized from salt crystallization. A technician from nearby Corte Madera might encounter this once a season; for us, it’s routine on Tiburon’s water-exposed elevations.
The housing stock here was built primarily in the 1950s through 1970s, with hillside homes engineered around Bay views. Most feature large aluminum-framed picture windows and sliding glass doors now failing after decades of salt exposure. Homeowners paying $3M and up for those views expect the largest, highest-performance glass systems available, specified correctly the first time.
There’s also a bureaucratic reality neighbors in Mill Valley or San Rafael don’t face: the Town of Tiburon’s Architectural and Site Design Review process requires approval for exterior alterations. We know the paperwork and the timeline, and we factor it into every project plan so you’re not surprised by a hold mid-job.
Our Main Tiburon Services
Most Tiburon homeowners call us for one of three projects: replacing corroded original windows, installing new openings in remodeled spaces, or upgrading to doors that actually seal against Bay winds.
Window Replacement in Tiburon
We remove fogged, corroded, or failed aluminum frames and install marine-specified replacements that hold up to salt air. In Tiburon, this almost always means aluminum-clad wood or fiberglass frames with stainless or marine-grade hardware, not standard residential-grade products. We handle the Architectural and Site Design Review documentation as part of the job. Window Replacement in Tiburon
Window Installation in Tiburon
New openings in hillside remodels or additions require structural assessment, flashing details that handle wind-driven rain, and glass specifications that preserve views without sacrificing thermal performance. We work with your contractor or architect to get the rough opening right before our crew arrives, and we protect floors and furniture with drop cloths throughout. Window Installation in Tiburon
Door Installation in Tiburon
Folding glass walls, multi-slide systems, and upgraded entry doors are common requests here, but standard hardware fails fast in this environment. We specify multi-point locking systems and marine-grade thresholds that seal against prevailing Bay winds, and we test every installation with a smoke pencil before we leave.

What Tiburon 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."
