Window, door & siding replacement in Tiburon, CA

Custom Exteriors replaces windows, entry doors, patio doors, and siding for Tiburon homeowners, with a focus on protecting bay views and standing up to wind and water exposure. We install Infinity from Marvin fiberglass windows, James Hardie fiber cement siding, and ProVia and Therma-Tru entry doors, using our own full-time AAMA Certified Master Installers, not subcontractors. We also handle the Town of Tiburon's permit process for you.

Why Tiburon homes need a different approach

In Tiburon, windows are the reason many homes were built where they are. Most of the town sits on a narrow peninsula surrounded by San Francisco Bay and Richardson Bay, and homes step up the hillsides to face the water, the city skyline, and Angel Island. Replacing those windows is about preserving the view as much as improving performance.

Tiburon has grown in layers. The railroad arrived in 1882 and made Point Tiburon a ferry terminal to San Francisco. Old Tiburon grew from one of the area's first residential developments, and the town incorporated in 1964. Today about 9,000 residents live in a mix of historic downtown cottages, midcentury hillside homes, and modern architectural houses.

With average home values above $3 million, homeowners here expect windows and siding that match the architecture and hold up for decades. Custom Exteriors has completed 30,000+ projects over 29 years with Infinity from Marvin, James Hardie, and ProVia and Therma-Tru products, exclusively. We do not install vinyl or builder-grade alternatives.

Wind, water, and fire considerations for Tiburon homeowners

Tiburon homes face the bay on nearly every side, so wind and moisture wear exteriors out faster than in inland towns. Afternoon wind off the water drives rain into worn weatherstripping and failing seals. Damp air keeps wood frames and siding wet, and strong sun on south- and east-facing view walls fades and dries finishes.

The right materials address each problem:

Fiberglass window frames do not rot, swell, or warp in damp conditions, and they hold a tight seal in wind.
Fiber cement siding resists moisture and will not rot, and its factory finish holds up to sun.
Title 24 glass packages, the glass options that meet California's state building energy code, cut heat gain from sunny view walls and heat loss on cool, windy evenings.

Parts of the Tiburon Peninsula also fall within designated Fire Hazard Severity Zones, especially near open space and wooded hillsides. The Tiburon Fire Protection District publishes a Wildland Urban Interface map, and you can check your address on the CAL FIRE Fire Hazard Severity Zone viewer.

Replacement windows and patio doors

Infinity from Marvin fiberglass windows are the window line we install in Tiburon because fiberglass keeps its seal and shape through years of wind, moisture, and sun. Fiberglass expands and contracts at nearly the same rate as glass, so the seal between frame and glass stays tighter over time than vinyl typically does. See our fiberglass versus vinyl comparison for the specifics.

Most Tiburon projects are built around the view:

Window walls and picture windows sized to keep sightlines to the bay, the city, and Angel Island as open as possible.
Casement windows that seal tightly against the frame, a good fit for wind-exposed hillside homes.
Double-hung windows with traditional profiles for Old Tiburon cottages and older homes.
Sliding, French, and bi-fold patio doors that open onto view decks and terraces.

We choose retrofit, block frame, or new construction installation based on your existing frames and any water damage we find in the openings. Our window installation methods guide explains each one. As an Infinity from Marvin Platinum Partner, Marvin's highest certification tier for Infinity dealers, we carry full-size displays in our Pleasanton showroom.

Entry door replacement

A new entry door is one of the most noticeable upgrades on a Tiburon home, and on a hillside lot it is often the first thing guests see after climbing the stairs. Original wood doors exposed to bay wind and moisture tend to swell, stick, and let in drafts. ProVia and Therma-Tru entry doors in fiberglass and steel resist warping and weathering far better.

Our design consultants help you choose a style, glass, and hardware that suit the house, from a traditional paneled door on an Old Tiburon cottage to a clean, modern entry on a contemporary hillside home.

James Hardie fiber cement siding

James Hardie fiber cement siding is the siding we recommend for Tiburon because it stands up to moisture, wind-driven rain, and sun without rotting or needing constant repainting. Wood siding on bay-facing walls often shows rot, peeling paint, and water staining long before the rest of the house.

James Hardie fiber cement is also noncombustible, a practical benefit for homes near the peninsula's open space. ColorPlus Technology, James Hardie's factory-applied finish, is baked on under controlled conditions, so it resists fading on sunny view walls better than siding painted on site. The siding is backed by a 30-year non-prorated product warranty and a 15-year ColorPlus finish warranty. We install James Hardie exclusively because after 29 years of evaluating siding, it is what we would put on our own homes.

If you are replacing siding, it is also the right time to replace windows with new construction installation, so each opening can be fully flashed and sealed.

Frequently asked questions

Q: Do I need a permit to replace windows in Tiburon?A: Yes. The Town of Tiburon requires a building permit for doors and windows that are added or replaced, and for siding. Custom Exteriors handles the permit application and inspections with the Town as part of your project.

Q: Will my window replacement need design review?A: It may. The Town of Tiburon requires separate design review approval for many exterior changes, depending on the scope of the project. We can help you understand what your project will likely need, and we recommend checking with the Town's Planning Division early so review does not delay your schedule.

Q: Can you replace large view windows without losing the view?A: Yes. Large-format window replacement means matching the original opening sizes and sightlines while upgrading the glass and seals. Our design consultants measure every opening and recommend the installation method that preserves the most glass area.

Q: How much does window replacement cost in Tiburon, CA?A: Cost depends on the number and size of your windows, the products and glass package you choose, the installation method, and site access. Large view windows and hillside homes with stair access typically cost more than standard installations. Review our window pricing factors and window cost guide before your consultation. We provide free, itemized estimates so you know what you are paying for before you decide.

Q: My Tiburon home was built before 1978. Does that change the project?A: It can. Homes built before 1978 may contain lead-based paint, and federal law requires lead-safe work practices on renovations that disturb painted surfaces in those homes. Custom Exteriors is EPA Lead-Safe Renovation, Repair, and Painting (RRP) Certified, and we confirm whether lead-safe procedures apply before installation begins.

Q: Do I have to visit the Pleasanton showroom to get an estimate?A: No. We offer free, no-pressure in-home consultations in Tiburon. The showroom is there if you want to see and handle full-size window, door, and siding displays first.
