San Jose's Craftsman bungalows, Queen Anne Victorians, and mid-century ranch homes sit on the flat Santa Clara Valley floor, where expansive clay soil and year-round termite pressure are part of every property owner's reality. When wood rot, soft floors, or termite damage shows up in your home, you need a carpenter who knows this valley and has been doing this work since 2016.

San Jose Carpentry handles wood rot repair, structural framing, termite damage, and finish carpentry for homeowners and property managers across San Jose and the surrounding area. We're fully insured, and we explain what we find before we quote the work. Our team does the job from start to finish, not a franchise crew rotating through your property.

Carpentry in San Jose (95112)

The Santa Clara Valley's clay and adobe soils shift with moisture, and that movement stresses sill plates, rim joists, and floor framing in ways that drier climates don't see. Add year-round termite pressure, both drywood and subterranean, and the wood in your walls and under your floors gets tested constantly. Homes built between the 1880s and 1940s in Naglee Park, Rose Garden, Willow Glen, and Japantown have the most elaborate trim, casing, and built-in details, and they're also the most vulnerable to rot in their older Douglas fir and redwood framing. Postwar ranch homes in Cambrian, Blossom Valley, and Evergreen sit on the same soil and face the same termite risk, but with simpler framing that's often easier to repair than replace. Tight lot access in many San Jose neighborhoods means we plan our approach carefully and keep our footprint small.

We've been serving San Jose homeowners and property managers since 2016, working through the specific conditions that come with this valley and this housing stock.

How a Job Works in San Jose

We start with a free on-site assessment. You show us the damage, the soft spot, the pest inspector's report, or the area you're worried about. We look at the wood, probe for rot, check the framing underneath, and explain what we see in plain language. We take photos and measurements, and we give you a straightforward estimate with a timeline and a price range.

Once you're ready, our team shows up with the tools and materials for the job. If it's structural work like beam replacement or floor joist repair, we'll talk through permit requirements with you and defer to your local building department for the final call on what needs approval. For finish work like crown molding, baseboard, or custom shelving, we'll scribe and fit everything to match your home's existing trim. We work methodically, protect your floors and furnishings, and clean up every day.

When the work is done, we walk through with you, answer questions, and leave your property clean. If you need to document the repair for an insurance claim, we can help you with photos and a written description of what we found and fixed.

Wood rot repair in a localized area of siding or trim starts around $650. If the rot has spread into a sill plate or the rim joist under your deck or porch, you're looking at $900 to $1,200 or more, depending on how much wood has to come out and what's underneath. Termite damage repair follows the same logic: a small section of damaged stud framing might be $1,200, but a full floor joist and subfloor replacement across several joists can run $1,800 to $3,500 or higher. Finish work is usually less, with interior door installation starting around $350, crown molding and baseboard at $450 to $550 per room, and custom built-ins from $1,900 on up. The big variables are size, access, how much of the wood is salvageable, and whether permits add time. Call us at (669) 202-8707 for a free estimate on your specific job.

I found soft wood in my deck frame in Willow Glen. Is this an emergency?

Not a panic, but don't wait. Soft wood under a deck or porch usually means rot is advancing into the joists and rim joist. The sooner you get it looked at and repaired, the less wood you'll lose and the less the repair will cost. Call us at (669) 202-8707 and we'll get someone out to assess it. A deck frame repair typically runs $900 to $1,500 depending on how much framing is affected.

My pest inspector found termite damage in my floor joists. What happens next?

Your pest inspector's report tells you where the damage is. We use that report to plan the repair. We'll remove the damaged sections of joist or subfloor, sister in new pressure-treated lumber or Douglas fir alongside the good wood, and restore the floor to solid footing. We don't treat termites or guarantee they won't come back, that's pest control. We repair and replace the wood they've damaged. Expect $1,800 to $3,500 for floor joist and subfloor work, depending on how many joists are involved and how much of the subfloor has to come up.

How much does it cost to replace a load-bearing beam or remove a wall in San Jose?

Beam replacement or load-bearing wall removal starts around $3,500 and goes up from there based on the span, the load it's carrying, and how much framing is in the way. These jobs almost always need a structural engineer to size the new beam and a permit from the city. We'll work with your engineer's drawings and handle the carpentry, but the engineer and the building department set the rules. Call (669) 202-8707 and we can walk you through the process.

Do I need a permit for wood rot repair or termite damage repair in San Jose?

Most wood rot and termite damage repair does not require a permit if you're replacing wood in kind, meaning you're putting back the same size and type of wood in the same location. Structural work like sistering joists, replacing beams, or altering a load-bearing wall usually does need a permit. The rules vary, so check with the San Jose Building Department to be sure. We can help you understand what the job involves, but the city has the final say on whether a permit applies.

We have an HOA in our Rose Garden neighborhood. Do they need to approve our carpentry work?

Many San Jose HOAs require approval for exterior work, structural changes, or visible alterations. Interior finish work like door installation or custom shelving usually doesn't need HOA sign-off, but exterior or structural work might. Check your CC&Rs and contact your HOA before you call us, or ask us and we can help you figure out what questions to ask. We work with HOA timelines and can coordinate with them if needed.

Are you fully insured for this work at my San Jose home?

Yes. We carry general liability and workers' compensation insurance. You can ask for a certificate of insurance before we start work. That protects you and your property while our team is on site.

What maintenance can I do to prevent wood rot and termite damage in my San Jose home?

Keep water away from your foundation and sill plate. Fix leaks in gutters, downspouts, and exterior trim quickly. Make sure soil and mulch don't pile against your siding or fascia. Have your pest inspector check your home every year or two, especially if you're in an older neighborhood like Naglee Park or Japantown where soil and moisture patterns favor termite activity. Trim tree branches away from your roof and siding so air can circulate. These habits cost nothing and save a lot of money over time.
