Mill Valley's redwood canyons and steep hillsides create a unique carpentry landscape: homes built on shifting foundations, wrapped in original millwork, and constantly challenged by moisture, shade, and wood decay.

San Francisco Carpentry has spent eight years repairing the structural and finish carpentry problems that define canyon living here in 94941. When your floor bounces, your deck frame softens, or your Victorian trim needs honest repair instead of replacement, we're the crew your neighbors call.

Residential Carpentry in Mill Valley (94941)

Mill Valley homes live under permanent shade and drip. The redwoods, Douglas firs, and canyon microclimate mean moisture works on wood year-round. Your sill plates and rim joists see constant dampness. Deck frames and fascia boards rot from the inside out. Older Victorians and Edwardians settle unevenly, twisting door jambs and floor joists out of square. Mid-century tract homes have original framing that's held up well but needs careful repair when rot or termite damage shows up. Lead-safe practices matter here too, since much of the housing stock predates 1978.

We've been doing this work in Mill Valley and the San Francisco area since 2016. We know how to read a hundred-year-old building, explain what's actually broken versus what's just settled, and propose repair before replacement whenever the wood justifies it.

How a Job Works in Mill Valley

Step 1: You call us at (628) 285-5429 or describe the problem. We schedule a free on-site assessment. We show up on time, look at the damage carefully, explain what we're seeing in plain language, and give you a realistic price range. No pressure, no sales pitch.

Step 2: Once you approve the work, our crew handles it. We're the same carpenters from start to finish, not a rotation of subcontractors. We work around your schedule, manage tight canyon lot access, coordinate with your HOA if needed, and handle lead-safe protocols on any pre-1978 work. We take photos of the damage and the repair so you can document it for insurance if that's relevant.

Step 3: We clean up thoroughly, haul away debris, and walk through the finished work with you. Your property gets left clean.

Wood rot repair in Mill Valley typically runs from $650 for small sill or trim work up to several thousand dollars for structural joists or beams. Termite damage repair starts at $1,200. Floor joist and subfloor repair begins at $1,800. Deck frame rebuilds, fascia and soffit repair, and exterior trim work range from $700 to $2,500 depending on damage extent and linear footage. Finish carpentry, crown molding, baseboard, and door installation are priced by the scope: $350 to $1,900 for most jobs. The main cost drivers are how much wood needs replacement versus repair, whether permits are required (structural work usually is), and site access. Call us at (628) 285-5429 for a free estimate on your specific job.

My deck frame is soft in one spot and the boards are pulling away from the rim joist. Is this dry rot or wet rot, and how urgent is it?

Soft wood in a Mill Valley deck almost always means moisture has been sitting there for months or years. The distinction between dry rot and wet rot matters to a scientist but not to you: the wood is compromised and needs replacement. It's not an emergency to panic about, but it should be looked at within a few weeks. Moisture will keep advancing. We can assess it, tell you exactly which boards and framing need replacement, and give you a price. Call (628) 285-5429 to schedule.

My pest inspector found termite damage in the sill plate and floor joist. What happens next?

The pest inspector found the damage; now we repair it. We don't treat or eliminate the termites, that's a separate licensed pest control trade. What we do is remove the damaged wood and replace it with sound framing. We work from your pest report, sistering new joists alongside damaged ones or replacing sill plates as needed. Depending on the extent, you may need a permit from the Mill Valley building department. We can help you navigate that. Call (628) 285-5429 to discuss.

How much does it cost to replace a rotted fascia and soffit on a Mill Valley canyon home?

Fascia and soffit repair in Mill Valley typically runs $700 to $1,500 depending on how many linear feet are involved and whether the underlying framing is sound or also needs work. If the rot has eaten into the rafter tails or blocking, the cost goes up. We assess it on site, measure the run, and give you a firm price. Many jobs here are a mix of repair and replacement. Call (628) 285-5429 for a free estimate.

Do I need a permit to replace a rotted floor joist or repair my deck frame in Mill Valley?

Yes, structural work usually requires a permit from the Mill Valley building department. Replacing floor joists, sistering rim joists, and deck frame repairs that involve load-bearing members typically need plan review and inspection. Some finish work doesn't, but when in doubt, we check. Permit requirements and thresholds vary, so we always defer to the local building department. We can help you prepare the paperwork and coordinate inspections.

My HOA says I need approval before I can rebuild my deck. How does that work?

Many Mill Valley neighborhoods have HOA design review. You'll typically submit plans or photos showing the scope of work, materials, and finish. We can help you prepare that documentation. Once you have HOA approval in writing, we schedule the work. If your deck is structural (load-bearing or attached to the house), the building department may also require a permit. We handle both processes and keep things moving.

Are you fully insured for carpentry work at my Mill Valley home?

Yes, we are fully insured with general liability and workers compensation. We're also an EPA Lead-Safe Certified Firm, which matters for any pre-1978 work in Mill Valley where lead paint is common. You can work with confidence that we follow the rules and protect your home and our crew.

My Victorian has sloping floors and doors that stick. Is this a structural problem or just settlement?

Mill Valley's hundred-year-old homes settle gradually and permanently. Sloping floors, out-of-square door openings, and sticking doors are the normal condition in older buildings here, not a sign of imminent failure. That said, if the slope has gotten noticeably worse in the last few years, or if you see new cracks or fresh rot, those are worth investigating. We can assess whether it's stable old settlement or active movement, and whether repair makes sense. Call (628) 285-5429 to schedule a look.
