THE SHORT ANSWER

Kaminskiy Care and Repair rebuilds rotted and termite-damaged wood on Sunnyvale homes from an office on Murphy Avenue, downtown: the exposed beam ends and fascia on the Eichlers in Fairbrae and the mid-century tracts in Cherry Chase and Birdland, the sills and door jambs the lawn sprinklers hit in Ponderosa Park and Raynor, the porch posts and trim on the Heritage District houses, and the balcony boards and railings on the condos and townhomes on the north side. Each is cut back to sound wood, rebuilt with the same profile, primed on every face, painted to match and sealed, with the sprinkler head or the drip line that caused it fixed. A licensed pest company treats the termites; we rebuild after them. The price is in writing before anything starts.

THE RIGHT WAY TO FIX ROT

Cut Out & Rebuilt in Sunnyvale

Sunnyvale sits in the dry, sunny end of the Bay, so its rot is a beam-end, bottom-board and sprinkler problem: the sun opens the paint on an exposed Eichler beam, the winter rain follows it in, and the lawn keeps the lowest boards wet all year. We cut back to sound wood, rebuild, prime, paint and move the water.

Why Sunnyvale wood rots

Sun and sprinklers. Sunnyvale is in the South Bay's rain shadow, drier and sunnier than the Peninsula, so the paint checks on the exposed beam ends, fascia and south walls first and the winter rain follows it into the end grain. At the ground, the lawn sprinklers keep the sills, the jamb bottoms and the post bases wet year round, which is where the subterranean termites come up. On an Eichler the roof beams run right through the wall to the outside, so a beam end is the first place we look.

Termites in the South Bay

The western subterranean termite is Sunnyvale's termite: it nests in the soil, needs the moisture there, builds mud tubes up a slab edge, a post or a planter wall to reach the wood, and swarms on a clear afternoon after a soaking rain. Drywood termites, the pellet-leaving kind, are far less common here than in Southern California. A licensed pest company treats the colony; we cut out and rebuild what it ate, scheduled after them so the wall opens once.

Rebuilding an Eichler beam end

An exposed beam end that has rotted is not a filler job. We cut it back to sound wood, scarf in new material with the same dimension and grain direction, back-prime it, set a drip kerf or a cap so water sheds instead of soaking, and paint or stain to match, so the beam reads as original from the street. If the rot has reached the part of the beam that carries the roof, we say so first and tell you who needs to look at it.

Keep it dry in Sunnyvale

Aim the sprinkler heads at the lawn, not the house, and keep soil and bark below the bottom board and the slab edge. Cap or flash the exposed beam ends and repaint the south and west faces before the paint fails. Clear the gutters before the first storm, and on a flat Eichler roof check that the scuppers and drains run clear.

SUNNYVALE, SOUTH TO NORTH

Where the house sits decides
where the rot starts

Kaminskiy has rebuilt rotted and termite-damaged wood on Sunnyvale homes since 2005, from an office downtown. The Eichler tracts, the middle of town and the north side rot in different places.
THE EICHLERS AND THE MID-CENTURY TRACTS

Fairbrae, Cherry Chase, Birdland, Las Palmas, Sunnyvale West

Post-and-beam houses with exposed beam ends, wide fascia, floor-to-ceiling glass and courtyard gates, and the ranch tracts around them with wood fascia and wood-framed windows, all from the 1950s and 1960s. The beam ends and the fascia check in the sun and soak in the rain, and sills and jambs rot at the lawn edge. We rebuild to the original profile and work to the city's Eichler design guidelines.

THE MIDDLE OF TOWN

the Heritage District around Murphy Avenue, Washington Park, Ponderosa Park, Raynor

Older houses with wood siding, porches, wood trim and mature trees, and 1960s and 1970s tracts with stucco and wood pop-out sills. Porch post bases, the bottom courses of siding and the sills on the shaded side go first. We splice new wood into the old, match the profile and keep the repair to what was there on the Heritage District streets.

THE NORTH SIDE

Lakewood, San Miguel, Fair Oaks, the condos and townhomes toward the Bay

Smaller lots, 1970s and 1980s condos and townhomes with wood balconies, stairs, trim and railings, now under California's balcony inspection law. When the association's report flags soft boards, a rotted post base or trim, we rebuild it and put the scope in writing for the board; a rotted ledger goes to the engineer first.

Sunnyvale is the South Bay office of a crew that covers the whole region; the Bay Area dry rot and wood rot repair page puts the East Bay, the Peninsula and the South Bay side by side, with every city's permit desk and the termite report explained.

WHAT A VISIT LOOKS LIKE

One call, a written price,
then the rebuild

01Call, or text a photo

A fascia board, a sill or a trim piece is priced on the call, in writing. A bigger rebuild gets a look first and a written price before anything starts.

02Open it up, find the edge

We cut back to sound wood and probe how far the rot really goes. If it runs further than the photo showed, you hear it before we go further, with the price.

03Rebuild, prime, paint, seal

New wood primed on all sides, caulked, painted to match, and the water path that caused it fixed: the drip edge, the flashing, the gutter end, the sprinkler.

04Clean up, warranty in writing

The work area is cleaned before we leave, and every rot repair carries our one-year workmanship warranty.

Not our lane, and we say so on the call: termite treatment, fumigation and inspection reports (a licensed pest company does those, and we rebuild after them), roof replacement, foundation work and structural engineering. If the rot has reached a beam or a ledger, we tell you what it needs before anyone opens a wall.
RULES WORTH KNOWING

Permits, termite reports and HOAs,
in plain words

Permits

Sunnyvale publishes its own sheet of work that does not require a building permit, with painting and similar cosmetic work on it and a note that the list is not all-inclusive and that each code carries more exemptions, which is where the state residential code's ordinary-repairs clause comes in: no application for an ordinary repair to a structure, never the cutting of a structural beam or a load-bearing support. A sill, a fascia board or a trim repair is that; a deck, a balcony rebuild or an Eichler beam cut back into the roof structure is a permit, and we tell you which on the call. Exterior paint on an Eichler or a Heritage District house can also need Planning's nod, and we check.

The termite report

A Sunnyvale sale carries a termite report from a licensed structural pest control company. Section 1 is the visible evidence: active infestation, or the damage termites and fungus left in a sill plate or a beam end. Section 2 is the conditions that invite them, such as a slab edge buried in planter soil or a sprinkler on the wall. The pest company treats and certifies; we rebuild the beam ends, sills, trim and deck boards on the list, and they reinspect. Send the report with the address and the repairs come back priced from it.

Condos and the balcony law

Most of Sunnyvale's single-family streets have no association; the Eichler tracts follow the city's design guidelines instead. The condos and townhomes, many on the north side, fall under California's law on exterior elevated elements: buildings of three or more attached units get an engineer's or an architect's inspection of their balconies, decks, walkways and railings on a nine-year cycle. Rot the report flags in a railing, a board, a post base or trim is our lane, and we write the scope for the board; a structural member goes back to the engineer first.

Call 408-916-4022

Our office is on Murphy Avenue, so a sill, a trim board or a fascia run is priced on the call and usually scheduled within days. An Eichler beam end gets a look first, and so does a balcony or a deck, with the scope in writing before anything starts.

Yes, once a licensed pest company has treated the colony. We cut out the eaten sill plates, trim, beam ends and the framing we can reach, and rebuild it. Treatment and the report are theirs; the carpentry is ours, scheduled after them.

Yes, when the rot is in the exposed end: we cut back to sound wood, scarf in new material with the same dimension and grain, cap it and finish it to match. Kaminskiy is licensed, bonded and insured. If the rot has reached the part of the beam that carries the roof, we tell you what it needs before anyone touches it.

The size of the rebuild once the wood is opened, the height and the access, and the match: a beam end scarfed to the original dimension takes longer than a sill. Text a photo and the price is in writing before anything is scheduled; if it runs further than the photo showed, you hear that before we go further.

Not for an ordinary repair: Sunnyvale's own sheet exempts painting and cosmetic work and points to the codes for the rest, and the state code asks no application for a repaired sill, fascia board or trim piece. A deck, a balcony rebuild, or rot into a beam that carries the roof is a permit, and we tell you on the call.

If the report flagged soft boards, a rotted railing post or damaged trim, yes, and we put the scope in writing for the board. A rotted ledger or a structural member goes back to the engineer first, and we say so on the call.

All of Sunnyvale from Murphy Avenue, including Cherry Chase, Fairbrae, Birdland, Las Palmas, the Heritage District, Ponderosa Park, Raynor, Lakewood and San Miguel, plus Mountain View, Cupertino, Santa Clara, Los Altos and San Jose. Call 408-916-4022 to confirm your address.
