Bay Area Siding Company re-sides homes across Fremont — the wooded lots climbing toward Mission Peak, the older cores of Niles and Mission San Jose, and the flat mid-century tracts that fill most of the valley. We're a Larkspur-based siding and window contractor working throughout the East Bay, and a replacement with us means the full job: stripping the old cladding, checking what's behind it, rebuilding the weather barrier and flashing, and installing new siding to the manufacturer's spec.

When a re-side beats another repair

Fremont's housing runs the gamut — postwar ranches and Eichler-era tracts on the flat, plus turn-of-the-century and craftsman stock in the historic districts. Different eras, same tell-tale signs that patching has run its course:

• Boards that cup, split, or give a little when you lean on them
• A repaint that blistered or peeled inside a season or two
• Punky, spongy material — or trim a screwdriver sinks into
• Interior wall stains, mildew, or a damp smell along an exterior wall
• Tired T1-11, hardboard, or chalky aluminum that's simply aged out

Re-side, don't wrap over

It's tempting to hang new siding over the old to save a step, but that buries the part of the wall that decides everything: the sheathing and whether a weather-resistive barrier is doing its job. On Fremont's older Niles and Mission San Jose homes especially, the flashing around windows and at the base of walls was often minimal or improvised, and you only find that out with the cladding off. Wrapping over also stacks weight on the wall and can seal moisture in. A true tear-off asks more of the budget up front and hands you a wall that's right from the sheathing out.

Picking a material

We install a range of systems and would rather talk you through them at your house than sell you one over the phone. The short version:

• James Hardie fiber cement — noncombustible and dimensionally stable; see the Fremont James Hardie page for how it plays in the foothill fire area
• Fiber cement — the wider category if you want other makers in the mix
• LP SmartSide — engineered wood with a warmer, deeper grain
• Vinyl — the lower-upkeep pick where the home and setting suit it

We also hang CertainTeed and wood siding, plus aluminum. If your lot is up in the hills east of Mission Boulevard, material isn't purely a style call — more on that below.

What to expect: our process

1. Consultation — we read the existing walls, hear your goals, and set a rough budget.
2. Measure and spec — accurate field measurements and a written scope of work.
3. Permit and any planning review — the City of Fremont Building Division permits a full re-side; we confirm scope and any historic-district or hillside considerations before we start.
4. Tear-off and substrate inspection — old siding down, and a look at sheathing and framing before anything new goes up.
5. Weather barrier and flashing — water-resistive barrier and flashing detailed to shed water at every opening and transition.
6. Install to spec — new siding fastened and gapped per the manufacturer's instructions.
7. Finish and walkthrough — trim, caulk, cleanup, and a final look together.

Fremont-specific things to know

The foothills are a different conversation than the flat. Fremont's eastern edge — the slopes below Mission Peak and around Mission San Jose — sits in the city's designated fire hazard severity zones, while most of the valley floor carries lower risk. In 2025 the City Council adopted a local map (Ordinance 10-2025, with the Fire Hazard Severity Zone map dated June 26, 2025) that follows Cal Fire's recommendations and adds some very-high areas of its own, and it adopted the 2025 California Wildland-Urban Interface Code by reference (Ordinance 12-2025). That code carries ignition-resistant and noncombustible requirements for exterior wall coverings in the interface — which is exactly why the siding material matters on a foothill lot and much less so down on the plain. Whether those provisions reach your project depends on your parcel's designation and the scope of work, so it's something we confirm with the City rather than assume. If you're up the hill, tell us early; it steers the material list.

Character districts. Niles and Mission San Jose have a strong sense of period identity, and a re-side there benefits from matching profiles, reveals, and trim to the era rather than defaulting to a generic board. We plan for that when we spec.

The valley-floor tracts. Across the flat, Fremont is full of mid-century and Eichler-era homes with long, clean wall runs — a re-side is a chance to correct decades-old flashing and end the paint-every-few-years cycle on aging wood or hardboard.

What affects the cost

We don't post prices because no two walls are alike. The real drivers are the size and number of stories, the material and finish you choose, how much concealed repair turns up once the old siding is off, window and trim integration, hillside access and staging on foothill lots, and any fire-area assembly detailing where the interface code applies. A walkthrough is the only honest way to price it.

We're based in Larkspur and work across the region — see finished jobs in our project gallery and the broader East Bay service area. Tackling the whole envelope? We also do window replacement and James Hardie siding in Fremont.

Frequently asked questions

Do I need a permit to replace siding in Fremont? A full re-side is permitted work through the City of Fremont Building Division. The exact submittal depends on scope, and homes in a historic district or a foothill fire area can carry added review — we confirm what applies to your address and handle the paperwork.

My house is up toward Mission Peak. Does that change my siding choices? It can. Fremont's foothill parcels fall in designated fire hazard zones, and the city's adopted wildland-urban interface code favors noncombustible or ignition-resistant wall assemblies. We verify your parcel's designation before speccing rather than assume a blanket rule.

Should I re-side over the old material or tear it off? For Fremont's older and mid-century homes we almost always recommend tear-off, so the sheathing, framing, weather barrier, and flashing can actually be seen and corrected. Wrapping over hides the problems that matter most.

How long will a re-side take? It depends on the home's size, the material, how much substrate repair we find at tear-off, and permitting. We give you a realistic window after measuring — not before.
