Our services

Our Carpentry Services in San Jose

All your work handled by qualified professionals in San Jose

Wood Rot & Dry Rot Repair

We cut back to sound wood, find the water that caused it, and rebuild to last.

Included in your service

  • Probing to map how far the decay actually runs
  • Decayed framing, siding and trim cut out, not filled over
  • Rebuilt in redwood, Douglas fir or primed rot-resistant stock
  • The moisture source traced and closed, or the rot returns
Learn more→

Termite Damage Repair

The exterminator handles the insects. We rebuild the wood they left behind.

Included in your service

  • We work from your pest inspection report, section by section
  • Eaten studs, sill plates, rim joists and subfloor replaced
  • Structural integrity restored before finishes go back on
  • No treatment, no fumigation: pest control is a separate trade
Learn more→

Floor Joist & Subfloor Repair

Soft, bouncy or sloping floors almost always start under the finish surface.

Included in your service

  • Joists, subfloor and bearing points inspected from below
  • Sistering where a joist is sound enough to keep
  • Full joist or subfloor replacement where it is not
  • Straight answer on what is old settling and what is real damage
Learn more→

Beam Replacement & Load-Bearing Wall Removal

Real structural carpentry: engineered beams, headers, and openings done to spec.

Included in your service

  • Temporary shoring set before anything load-bearing comes out
  • Engineered beams and headers installed to the drawings
  • We say plainly when your job needs a structural engineer first
  • Built to the permit set, ready for city inspection
Learn more→

Framing & Structural Carpentry

Straight, plumb and square: the bones every finish detail depends on.

Included in your service

  • New interior walls, openings, garage and basement build-outs
  • Stud framing, headers and blocking sized for the span
  • Fire and water damaged framing cut back and rebuilt
  • Laid out so drywall, trim and cabinets land where they should
Learn more→

Finish & Trim Carpentry

Tight miters, scribed fits, consistent reveals. This is where a carpenter shows.

Included in your service

  • Casing, paneling and wainscoting fitted to the room as built
  • Scribing to walls that are neither flat nor plumb
  • Coped joints on inside corners instead of caulked gaps
  • Profiles matched to existing Victorian and Edwardian millwork
Learn more→

Crown Molding & Baseboard Installation

Crown, base and casing cut for the ceiling you actually have, not a perfect one.

Included in your service

  • Coped inside corners, mitered and glued outside corners
  • Baseboard, chair rail and window trim run to a clean line
  • Period profiles matched or kept crisp and modern, your call
  • Filled, sanded and caulked ready for paint
Learn more→

Custom Built-Ins & Shelving

Built for the alcove you have: bay windows, sloped ceilings, awkward corners.

Included in your service

  • Bookshelves, window seats, media walls and Murphy beds
  • Designed around compact floor plans, not around stock sizes
  • Scribed and shimmed so nothing reads as an add-on
  • Face frames, doors and drawers aligned before we leave
Learn more→

Interior Door Installation & Repair

Doors that stick or swing open on their own are usually the frame, not the door.

Included in your service

  • Jamb, hinges and reveal checked before anything is replaced
  • Doors hung, planed and adjusted to a settled opening
  • Damaged jambs and door frames repaired rather than swapped
  • Pocket and barn door hardware installed and tuned
Learn more→

Exterior & Entry Door Installation

Entry, back and French doors set weather-tight against fog and wind-driven rain.

Included in your service

  • Opening flashed and sill pan set before the unit goes in
  • Rotted frames and thresholds repaired or fully replaced
  • Shimmed plumb so the door seals along its whole edge
  • Weatherstripping, hardware and strike plates fitted properly
Learn more→

Cabinet & Vanity Installation

Level cabinets in a house where almost nothing is level. That is the whole job.

Included in your service

  • Floors and walls checked and a true level line struck first
  • Boxes shimmed, scribed to out-of-square walls and fastened
  • Kitchen, bath vanity and laundry storage set as one run
  • Doors, drawers and hardware aligned and adjusted at the end
Learn more→

Stair & Railing Repair

Squeaky treads and loose banisters, repaired without rebuilding the whole stair.

Included in your service

  • Stringers, treads and risers checked for wear and movement
  • Loose newel posts and balusters re-anchored, not just glued
  • Period railings restored where the original stock is sound
  • Handrails and attic ladders installed to code height and grip
Learn more→

Deck & Porch Repair

Repair first. We only recommend replacing when the framing no longer justifies it.

Included in your service

  • Boards, posts, stairs and framing probed for hidden decay
  • Rotted members replaced, sound structure kept and reused
  • Ledger connection and flashing checked where the deck meets the house
  • An honest repair-versus-replace number before work starts
Learn more→

Fascia, Soffit & Exterior Trim Repair

Soft fascia and peeling paint at the roofline are the first sign of rot moving in.

Included in your service

  • Fascia, soffit and exterior trim replaced back to sound wood
  • Primed rot-resistant material on all six faces before install
  • Gaps closed so moisture and pests stop getting into the roofline
  • Ready for paint, with the water path corrected first
