How much does dry rot repair cost in Granite Bay?

Where do the Granite Bay dry rot repair cost ranges come from?

Dry rot is priced by the location and by the foot, not by the house, and the published figures reflect that. homeyou's 2026 Granite Bay page prices a single wood rot repair at about $357 to $409 per damaged area: about 7.8 hours of labor at $266 to $293, $63 to $68 in materials and supplies, and $29 to $48 in equipment. That is one sill, one trim piece, or one section of fascia. homeyou's separate Granite Bay siding repair page puts a section of about 108 square feet at roughly $527 to $724, or $5 to $7 per square foot, which is the figure for rot that has reached the bottom courses of cedar or T1-11.

What adds to dry rot repair cost in Granite Bay neighborhoods?

Dry rot follows the water, and in Granite Bay the water follows the trees and the trim details of each era. About 39% of homes predate 1980 and another 24% are from the 1990s (U.S. Census Bureau, ACS 2020–2024 5-year); the two groups rot in different places.

• Auburn-Folsom Road, Barton Road, and Cavitt Stallman Road acreage. Open eaves with exposed rafter tails and wide cedar fascia rot behind gutters that have overflowed with oak leaves and pine needles; bottom courses of cedar and T1-11 go soft above planter beds with drip irrigation; post bases rot where they meet a slab or deck; and the original aluminum sliders sit in openings that may lack effective flashing. Adders: many locations per house, rafter-tail and ledger work that is permitted structural repair, long fascia runs at Handoff's per-foot rate, and lead-safe containment on painted wood where covered painted surfaces are disturbed on a home built before 1978.
• Treelake Village and Douglas Ranch. 1990s two-story stucco with finger-joint pine trim: belly bands, pot shelves, and garage surrounds rot from the back where the existing top-edge flashing should be inspected. Adders: per-foot trim replacement, cap flashing over every horizontal trim piece, stucco patching and color match at each cut, and second-story reach. The HOA reviews a change in visible material or color; matching the profile does not by itself establish an exemption from architectural review.
• Los Lagos. Heavy cedar trim and board-and-batten gables on stucco bodies, so the rot is in the trim rather than the wall, with association review of anything that changes the street elevation.
• Wexford and the newer customs. Foam trim does not rot, but the wood framing behind a failed foam corner or a pot shelf can, and manufactured stone that may lack effective flashing at its top edge sends water into the wall. Repairs here are fewer and more surgical.
• Folsom Lake and Beals Point edge. On parcels CAL FIRE maps in a fire hazard severity zone, Placer County may require that repaired eaves and low trim go back as non-combustible or ignition-resistant materials with ember-resistant vents, which cost more than primed pine and standard louvers.
• Granite Bay Hills. Two-story eaves over sloped decomposed-granite lots, where the downhill side is lift work and the downspouts that caused the rot need rerouting below the house.

Local cost factors in Granite Bay

Placer County Building Services is the permit authority for unincorporated Granite Bay. Confirm the requirements for the complete trim, siding and structural repair scope before removal. Rafter tails, sheathing, ledgers and framing deserve separate review; a decorative-board description does not establish that all associated work is exempt. The estimate should distinguish confirmed repairs from allowances, identify any required plans and inspections and name the applicant. Confirm actual fees with the county rather than treating a publisher's estimate as the schedule.

A 1970s construction date alone does not establish whether a home predates 1978. Confirm the year and have the contractor determine the EPA RRP requirements for the painted surfaces being disturbed. The firm must be EPA-certified, contain the work area, and clean up with lead-safe practices, which adds setup and cleanup to each location. Ask how work areas can be safely grouped and what containment the actual repair sequence requires.

Granite Bay is Title 24 climate zone 11 with summers over 100°F and winter rain from November to March, and the canopy is what makes its rot pattern different from the valley floor. North and east walls under blue oak, interior live oak, gray pine, and planted redwoods stay damp into May, gutters fill with needles year-round, and eaves rot from the top, behind the gutter, where no one sees it until the fascia sags. Native oaks in the Granite Bay Community Plan area are protected under Placer County's tree preservation ordinance, so clearance for a lift at the eave is a county question before it is a pruning question.

Soils are decomposed granite over bedrock, often sloped, so the water-path correction on many Granite Bay jobs is the downspout: rerouting it below the house is what stops the post base or the bottom course from rotting again.

Most of the community is PG&E territory, and dry rot repair carries no utility rebate. Disposal is modest for trim and larger when a bottom course of siding or a run of fascia comes off a big custom.

Add-ons Granite Bay homeowners pair with dry rot repair

• Gutters and downspout rerouting. The overflowing gutter and the downspout at the foundation are usually the cause; new runs and discharge lines stop the recurrence. The gutter installation cost guide covers the per-foot figures.
• Painting. New trim and fascia need primer and two coats, and a whole-house repaint often follows a whole-house rot scope; the exterior painting cost guide has the Granite Bay ranges.
• Window replacement at rotted sills. When the sill under an original aluminum slider is gone, a full-frame window with a sill pan is the durable fix; the window replacement cost guide covers the per-opening numbers.
• Siding on the worst wall. When rot has reached the sheathing on a north wall, replacing that wall is the honest scope; the siding cost guide has the per-square-foot rates.
• Ember-resistant vents and eave hardening. On lake-edge parcels, rebuilt eaves go back with listed vents and non-combustible materials under the same mobilization.

Reading two dry rot repair bids side by side

Compare the location list before the total. A complete dry rot bid names each location, states what is removed and what replaces it, gives a per-foot rate for fascia and trim and a per-item price for structural repairs, separates permitted structural work from trim, names the water-path correction at each location, and says whether paint is included. The lines most often missing from the lower bid are the flashing and rerouting that keep the rot from coming back, the lead-safe practices on a pre-1978 house, and the structural items that need a Placer County permit. A bid that patches the symptom is cheaper because it is a different job.

The estimate comparison guide walks through the method, and the signs of dry rot guide shows what to probe before anyone arrives. For a written scope on your own house, request an estimate and note which pieces are soft, whether the house is a 1970s cedar custom or a 1990s stucco home, the trees over each side, and whether it is in Los Lagos, Treelake Village, or Wexford. The dry rot and trim service page lists a complete scope, and the Granite Bay service area page describes the community's housing.
