Piedmont Siding & Windows Replacement

Piedmont's housing is some of the most carefully built in the East Bay — Tudor, Mediterranean, and period-revival homes on streets where how the exterior reads genuinely matters. Bay Area Siding Company is a Larkspur-based siding and window contractor, and when we re-side a home here we treat the whole wall as one system: strip the old cladding, look at what's underneath, rebuild the water barrier and flashing, and install new siding that suits both the architecture and the city's review expectations.

When a re-side beats another repair

Homes of Piedmont's era were framed long before drainage planes and modern flashing were routine, so cladding problems here often trace back to the wall assembly rather than the surface. It's usually time to replace rather than patch again when you notice:

• Stucco that keeps cracking back open, or siding boards that cup, split, or move under hand pressure
• A fresh paint job that blisters or peels within a season or two
• Punky, spongy wood at trim, corners, or the base of walls where a screwdriver sinks in
• Damp, musty interior walls, or staining that shows up after wind-driven rain
• Original wood siding, early stucco, or dated panel products that have simply reached the end of their life

Re-side, don't bury it

It's tempting to fur out and clad over what's there, but that hides the sheathing exactly where an older Piedmont home is most likely to have concealed rot — around windows, at wall-to-roof transitions, and along the mudsill. Covering over also stacks weight on the wall and can seal moisture in. Pulling the old material lets us verify there's a real weather-resistive barrier (many homes this age never had one) and correct flashing before a single new board goes up. It costs more at the outset and leaves you with a wall that's sound from the sheathing out.

Picking the right material

We install a range of systems and would rather walk your home with you than push one product. The starting points:

• James Hardie fiber cement — noncombustible and dimensionally stable; the detail-friendly choice for period homes and for parcels in Piedmont's fire zone (the Piedmont James Hardie page goes deeper)
• Fiber cement — the wider category if you want to compare manufacturers
• LP SmartSide — engineered wood with a warm, real-wood look
• Vinyl siding — a lower-maintenance option where the home and setting suit it

We also work in wood, CertainTeed, and aluminum. On Piedmont's southeastern parcels, material choice carries an added fire consideration covered below.

What to expect: our process

1. Consultation — we walk the exterior, talk through what's failing and what you want the home to look like when it's done.
2. Measure and spec — accurate measurements and a written scope, including how we'll match or refine the existing profiles.
3. Permit and design review — we prepare the building permit and, where a material or appearance change calls for it, the design-review submittal Piedmont expects.
4. Tear-off and substrate inspection — old cladding comes off and we assess sheathing, framing, and any hidden moisture damage before rebuilding.
5. Weather barrier and flashing — a proper water-resistive barrier and flashing at every opening, penetration, and transition.
6. Install to spec — new siding set to the manufacturer's clearance, fastening, and joint requirements.
7. Finish and walkthrough — trim, caulk, paint or finish as specified, full cleanup, and a final review together.

Piedmont-specific things to know

Design review is part of the culture here. Piedmont reviews exterior work closely. Normal repairs and maintenance with no change in materials, design, or size are generally exempt, but changing the cladding material or a home's exterior appearance can put a project into design review before the building permit issues. Because it shapes both timeline and what profiles and colors get approved, we sort out the review path with the Planning & Building Department (120 Vista Avenue) early rather than after the fact.

About a fifth of the city is a Very High Fire Hazard Severity Zone. In 2020 Piedmont adopted Ordinance 755 N.S., designating its southeastern section — roughly the area around Park Boulevard, St. James Drive, and Tyson Lake, about 20% of the city — as a Very High Fire Hazard Severity Zone, along with citywide defensible-space and vegetation-management standards (including a 30-foot defensible perimeter around structures in the zone). For a re-side, that's relevant because California Building Code Chapter 7A governs exterior wall coverings in these areas and generally points toward noncombustible or ignition-resistant assemblies. Whether and how 7A applies comes down to your specific parcel, the product, and the scope of work, so it's something we confirm with the City rather than assume. If your home sits in or near that southeastern zone, tell us up front — it changes the material conversation.

High-value period stock rewards careful detailing. The Tudors, Mediterranean-style homes, and revival houses that define Piedmont's streets have distinctive trim, reveals, and massing. A re-side that respects those details — rather than flattening them — protects both the character and the value of the home, which is where matching profiles and finish selection earn their keep.

Doing more than the walls? We also handle window replacement in Piedmont, and you can see finished work in our project gallery or across the wider East Bay.

What affects the cost

Every home is different, so we don't post prices. The real drivers are the size and number of stories, how much concealed repair turns up at tear-off, the material and finish you choose, the complexity of trim and detailing on a period home, whether design review is triggered by an appearance change, and any fire-zone assembly requirements on southeastern parcels. A walkthrough is the only way to price it honestly.

Frequently asked questions

Do I need a permit to replace siding in Piedmont? Plan on it. A full re-side is more than routine maintenance, and changing the exterior material or appearance can also require design review through the Planning & Building Department before the building permit is issued. We prepare both.

My home is in the southeastern fire zone. Does that limit my options? It can. Homes in Piedmont's Very High Fire Hazard Severity Zone are subject to Chapter 7A provisions that favor noncombustible or ignition-resistant wall assemblies. We confirm what applies to your parcel before speccing the material.

Can you keep the look of a Tudor or Mediterranean home? Yes. Profile, reveal, and finish can be chosen to hold a period home's character; fiber cement in particular can mimic wood detailing convincingly while lasting far longer.

Should I re-side over the old material instead of tearing off? On homes of Piedmont's age we recommend tear-off. It's the only way to inspect and correct the sheathing, framing, weather barrier, and flashing — covering over just conceals the parts most likely to be failing.
