Bay Area Siding Company re-sides homes throughout Hidden Valley Lake, the gated lake community in southern Lake County near Middletown. We're a Marin-based siding and window contractor, and on a wooded, fire-exposed lot the material you put back on the wall is not a small decision. We take the whole job from the wall out: removing the old cladding, checking what's behind it, correcting the water and flashing details, and installing a new exterior that's built for where this community actually sits.

Why the material matters more here than in most towns

Hidden Valley Lake sits in fire country, and everyone here knows it. The 2015 Valley Fire ignited near Cobb on September 12 and burned more than 76,000 acres, destroying close to 2,000 structures across Cobb, Middletown, Whispering Pines, and the southern end of Hidden Valley Lake. A decade on, the neighborhood is a mix of rebuilds and homes that came through — and for both, a re-side is a chance to put a more fire-resilient skin on the house.

That's why, around the lake, choosing cladding isn't only about curb appeal. On a hillside or wooded parcel in a high fire-hazard area, noncombustible and ignition-resistant materials are worth taking seriously. Where a parcel carries a Fire Hazard Severity Zone or Wildland-Urban Interface designation, California Building Code Chapter 7A can govern the exterior wall covering — favoring noncombustible or tested ignition-resistant assemblies. Whether it applies to your specific project depends on the parcel's designation, the product, and the scope of work, so we confirm that with the county before speccing rather than assuming a blanket rule.

What comes off, and what we find underneath

A re-side is the one moment the wall is open, so it's worth doing right. When the old cladding comes off, we're not exposing the framing — a standard tear-off removes the siding down to the sheathing/substrate, which is what lets us actually inspect the water-resistive barrier (WRB) and flashing and see whether they were ever installed correctly.

That inspection is the argument against covering old siding with new. Layering hides exactly what you'd want to check on an older home: soft or rotted sheathing, missing or torn WRB, and flashing gaps around windows and at wall bases where water gets in. It also adds weight and can trap moisture against the wall. Taking the old material off costs more up front and leaves you with a wall that's sound from the sheathing out — and, on a fire-exposed lot, one built from a material you chose deliberately.

Signs a Hidden Valley Lake home is past patching:

• Cracked, split, or warped boards, or sections that give when you press them
• Fresh paint that fails again within a season or two
• Trim or siding soft enough to take a screwdriver
• Musty smells or staining on interior walls near the exterior
• Aging T1-11, hardboard, or other cladding at the end of its life

Picking the cladding

We install several systems and will walk the trade-offs with you on site. On a high fire-hazard parcel the shortlist usually starts with the noncombustible options:

• James Hardie fiber cement — noncombustible fiber cement; see our Hidden Valley Lake James Hardie page for the fire-zone details
• Fiber cement generally — the broader category across manufacturers
• LP SmartSide — engineered wood, where it's an appropriate fit
• Vinyl siding — a lower-maintenance choice on parcels where it suits the exposure and the rules

We also work in wood, CertainTeed, and aluminum. Which of these is right depends heavily on your parcel's fire designation and on the community's own standards, covered next.

Two approvals, not one

This is the part that surprises homeowners who've built elsewhere. A Hidden Valley Lake re-side generally clears two gates:

1. Lake County permit. Hidden Valley Lake is unincorporated, so building permits run through the Lake County Community Development Department, Building Division — not a city hall. Their building technicians can confirm whether your scope needs a permit and how fire-zone provisions apply to your address.
2. HOA architectural review. Because the community is a gated, master-planned development, the Hidden Valley Lake Association reviews exterior changes through its Environmental Control Committee before work starts — that can include siding material, profile, and paint color. It's a genuine second step, and planning for it early keeps a project from stalling.

We factor both into the schedule so the timeline you get is realistic, not optimistic.

What drives the cost

We don't post prices, because the honest drivers are all job-specific: the size and number of stories of the home; hillside or wooded access and staging; how much concealed substrate or WRB repair turns up at tear-off; the cladding system and finish you choose; whether fire-zone assembly detailing applies to the parcel; and any conditions attached during Environmental Control Committee review. A walkthrough is the only way to price it honestly.

How the job runs

After we measure and write a scope, we handle the county permit and HOA submittal, then schedule tear-off. Old cladding comes off, the sheathing and WRB get inspected and repaired as needed, flashing and a fresh weather barrier go on, and the new siding is installed to the manufacturer's specs — followed by trim, finish, cleanup, and a walkthrough with you.

FAQ

Do I need a permit to re-side a house in Hidden Valley Lake? Because Hidden Valley Lake is unincorporated, permits go through the Lake County Community Development Department's Building Division rather than a city. On top of that, the Hidden Valley Lake Association's Environmental Control Committee reviews exterior changes. We handle both submittals.

Does the fire zone limit my siding choices? It can. On parcels with a Fire Hazard Severity Zone or WUI designation, Chapter 7A can require noncombustible or ignition-resistant wall coverings. Whether it applies to your project depends on your parcel and scope, which we confirm with the county before speccing.

Should I re-side over the old material to save money? On most homes here we recommend a full tear-off. Covering over hides the sheathing, water barrier, and flashing — the parts most worth inspecting on an older or fire-exposed home — and adds weight that can trap moisture.

How long does a re-side take? It depends on the home's size, access, what we find at tear-off, and the two-track approval. We give you a realistic window once we've measured and know the parcel.
