Siding for the Caldor Fire Rebuild in Grizzly Flats, CA

Exterior work in Grizzly Flats

Grizzly Flats is a small unincorporated community of about 1,200 people before the fire, reached by Grizzly Flat Road south of Pollock Pines and Sly Park, sitting near 4,000 feet in El Dorado County's mixed-conifer belt. On August 14, 2021, the Caldor Fire started in the Middle Fork Cosumnes drainage a few miles away, and within its first days it overran the town — roughly two-thirds of the homes were destroyed, along with the elementary school, the post office, and the community church, before the fire ran east across the Sierra crest toward the Tahoe Basin. Nearly five years on, siding work in Grizzly Flats means one of two things: cladding a new house rising on a burned lot, or retrofitting one of the structures the fire spared. We do both, and we hold each to the standard this community paid so much to learn.

A rebuild moving at its own pace

Grizzly Flats' recovery has been slower than the better-known rebuilds elsewhere in the state, and honesty about that belongs in any conversation about working here. The community is small, many owners were underinsured for mountain construction costs, and local infrastructure — including the community's small water system — took heavy damage that had to be repaired before houses could follow. Some streets have new homes finished and occupied; others still hold cleared pads where families are weighing whether and when to return. None of that changes what the work itself requires. Every new wall going up in Grizzly Flats falls under California's current WUI construction code, and every surviving cabin deserves an exterior that closes the gaps the old one had.

Grizzly Flats housing after the fire

The housing stock here now divides cleanly by a single date. Homes finished since 2021 were permitted under the state's wildland-urban interface requirements and generally carry ignition-resistant exteriors from day one — for these, our role is cladding installation coordinated with the builder's envelope, or later repair and additions matched to the rated assembly already in place. The survivors are the older story: forest cabins, manufactured homes, and mountain houses from earlier decades, many still wearing the sawn-wood or plywood-panel exteriors typical of when they were built. A surviving Grizzly Flats home with its original combustible skin is carrying a known vulnerability in a landscape that has already demonstrated the consequence, and re-cladding it is the most meaningful exterior investment its owner can make.

Materials for the Grizzly Flats rebuild

Our recommendation in Grizzly Flats does not hedge: the field of the wall should be Class A fiber cement, full stop. James Hardie systems are our usual specification, in lap or panel profiles depending on the house, with trim and fascia chosen to match the cladding's fire behavior rather than reintroduce wood at the edges. Fiber cement earns its place on the winter side of the ledger too — it is dimensionally stable through freeze cycles that swell and split sawn wood, and factory finishes hold up under high-elevation sun. We put product names, ratings, and assembly details into the written scope on every job, because in a post-fire community that paperwork carries real weight with building departments and insurance reviewers alike.

Pricing exterior work in Grizzly Flats

Costs here reflect mountain rebuild conditions. Grizzly Flat Road is a long approach for material deliveries, crews travel farther than they would to a valley job, and the working season is compressed by winter at this elevation. On new construction, cladding cost is largely set by the plans and the code — the WUI detailing is not an add-on but the baseline. On surviving homes, the main variable is what decades-old siding has been hiding: weathered sheathing, past leaks, and framing repairs are common discoveries once the old skin comes off, and we would rather flag that possibility up front than surprise an owner mid-project. Every Grizzly Flats quote follows a site visit, itemizes the scope in writing, and stands as written.

New builds and survivors are different projects

We scope these two situations differently because they are different. A new build is a coordination job — working with the owner or builder so the cladding, flashing, and penetrations land correctly within an envelope that is already designed to current code, with nothing lost between trades. A survivor retrofit is a discovery job — opening up an older wall, correcting what time and the fire's heat may have done beneath it, and bringing the exterior up to a standard the house never had. Both end in the same place, a rated and documented wall, but the path and the budget conversation differ, and we set expectations accordingly at the first walk-through.

Working in a community still recovering

Job-site conduct matters more in Grizzly Flats than in most places we work. Crews here operate on streets where neighbors have lived through total loss, where burned trees are still coming down, and where construction traffic shares a narrow road with residents rebuilding their lives. We stage tightly, keep sites clean, protect the defensible clearance owners have worked to establish, and schedule around the realities of a mountain community rather than treating it as a remote address on a route sheet. Small-town rebuild work is relationship work, and we treat it that way.

Snow country detailing on a fire-country wall

The details that matter most here sit where the two hazards overlap. The base of the wall needs noncombustible clearance for embers and simultaneously needs to stand clear of snow that piles against the foundation through winter storms. Flashing at rooflines and penetrations must block wind-driven ember entry in September and shed meltwater in March. We build those junctions once, for both problems, using cold-climate flashing practice inside an ignition-resistant assembly — because a Grizzly Flats wall that solves only one season's hazard has only done half its job.
