THE FIX MOST DECKS NEED

Sunnyvale Deck and Balcony Repair

A Sunnyvale deck is a low redwood deck off the glass wall of a Cherry Chase or Fairbrae Eichler, built close to the ground where the sprinklers keep it wet and the subterranean termites come up, a porch and steps on a Heritage District house from the 1910s, or a wood balcony and stair on a 1970s condo building in Lakewood or San Miguel that the association's engineer has just inspected. We replace the soft boards, reset the posts on standoffs, rebuild the steps, correct the flashing where the deck meets the house, sand, stain and seal, and keep the Eichler lines where the city's guidelines care about them.

The low deck off the Eichler is soft at the edge nearest the lawn sprinkler.
Mud tubes run up a post base, the sign of subterranean termites in a wet deck.
The top boards have checked and gone gray on the south side by August.
The rail post at the porch steps moves and the lag screws spin in soft wood.
The bottom step sits on bare dirt and the stringer has gone dark.
The condo board's engineer flagged the balcony decking and a loose rail on your building.

Our office is a few minutes from every one of these. A Kaminskiy-certified technician prices the small ones from a photo; a frame or a balcony gets a look first and a written scope.

THE DECK & BALCONY GUIDE

Why Sunnyvale decks go soft

Sun, sprinklers and sixty years. Sunnyvale sits in the dry, sunny end of the Bay, so the finish checks on the south boards and the beam ends first and the winter rain follows it into the end grain. Underneath, the lawn sprinklers keep the post bases and the low joists wet all year, which is where the subterranean termites come up, and valley clay that moves with the seasons loosens the post and railing connections. A low Eichler deck fails from the frame up under boards that look fine, which is why we probe before we quote.

The railing test

Lean into each post, at the porch steps and at the deck corner. If it moves, the post has lost its connection: a base rotted or eaten at the ground, a lag screw spinning in soft wood, or a rim joist gone behind it. We cut back to sound wood, through-bolt the post to the framing with a tension tie, and set the rail to hold an adult leaning on it. A railing we cannot make solid is replaced, and on a Heritage District porch we match the one that was there.

Balconies, SB 721 and SB 326 in Sunnyvale

The condo and townhome buildings toward the Bay are where Sunnyvale meets SB 326, the condominium version of the balcony inspection law, and the apartment buildings with three or more units meet SB 721; both send an engineer or a licensed inspector to the wood-framed balconies, stairs and walkways and a report to the board or the owner. The decking, joists, railings, flashing and waterproofing that report flags are our work, scoped in writing and done to the re-inspection standard with photos for the file. A failed ledger or a balcony that has moved is the engineer's to stamp first. The inspection itself, the report and the deadlines are on our Sunnyvale SB 721 page, linked from this one.

Keeping a Sunnyvale deck solid

Turn the sprinkler heads away from the deck and the post bases, keep the gaps clear so the boards drain, cap or flash the beam ends and recoat the sun side before the finish fails, and look under a low deck each spring for mud tubes and soft joists. Press a screwdriver into every post base, the step stringers and the ledger line once a year. A soft board found in spring is a visit; a frame the termites found is a rebuild on standoffs and a call to the licensed pest company first.

SUNNYVALE, SOUTH TO NORTH

The Sunnyvale deck,
house by house

Kaminskiy has repaired Sunnyvale homes since 2005 from an office downtown on Murphy Avenue. A low Eichler deck, a Heritage District porch and a north-side condo balcony fail in different places.
THE EICHLERS AND THE MID-CENTURY TRACTS

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

Post-and-beam houses with glass walls opening onto low redwood decks and patios, and the 1950s and 1960s ranch tracts around them with porches, steps and open-beam patio covers. The decks sit inches off the ground, so the sprinklers keep the frame wet, the subterranean termites come up through the post bases and the joists go before the boards do, while the sun checks the top boards and the beam ends. We rebuild the frame on standoffs, replace the boards to the same width and reveal, cap the beam ends, and keep the flush lines the city's Eichler guidelines expect.

THE MIDDLE OF TOWN

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

The oldest houses in the city, some from the 1900s to the 1930s, with wood porches, steps and railings worth keeping, beside 1960s and 1970s stucco tracts with rear decks and patio covers. Porch posts rot at the base where the walk meets them, the step stringers sit on dirt, the railings loosen in old framing, and on the tracts the deck boards split and the ledger flashing was never there. We rebuild the posts and steps to the profile that was there, through-bolt the railings, correct the flashing and match the paint or stain.

THE NORTH SIDE

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

Compact 1950s homes with small rear decks, and 1970s and 1980s condo and townhome buildings with wood balconies, exterior stairs and railings now under California's balcony inspection law. The report lists soft decking, a rotted post base, a railing that moves or a membrane that holds water; that carpentry and membrane work is ours, scoped in writing for the board with photos for the re-inspection, and a structural member goes back to the engineer first.

WHAT A VISIT LOOKS LIKE

One call, priced
before we come

01Call or text photos

Call 408-916-4022 or text a photo of the soft board, the post base and the railing. Our office is a few minutes away, so most Sunnyvale deck repairs get a range on the call and a look within days.

02The look and the written scope

A technician probes the posts, the joists under a low deck, the step stringers and the ledger, leans on every railing, looks for mud tubes, and writes the scope: what comes out, what gets refinished, whether the pest company, the engineer or the city has to see anything, and the price.

03The repair

Boards and treads replaced, the frame rebuilt on standoffs where the termites or the sprinklers got it, posts reset, railings through-bolted, beam ends capped, flashing corrected, usually in a day or two on a residential deck.

04Sand, stain, seal, warranty in writing

The surface is sanded and stained or sealed once the new wood is dry, the cut-offs leave with us, and the one-year workmanship warranty is on the invoice at the price you approved.

Not our lane in California: a new deck on a new footprint or a balcony that has moved, which an engineer must design or stamp first; a failed ledger or a beam that carries the Eichler roof, which goes to the engineer before we touch it; deck lighting, which a licensed electrician wires; and the termite treatment, which the licensed pest company does before we rebuild.
RULES WORTH KNOWING

Licenses, Sunnyvale permits and
the Eichler guidelines, in plain words

Who can do the work

Under California law a job below a small set amount may be done without a contractor license, but only when no permit is needed and no one is employed to do it; a deck frame on standoffs, a railing run or a balcony report item reaches past that line. Kaminskiy Care and Repair is a licensed California contractor (License #1106209), bonded and insured, with Kaminskiy-certified, background checked technicians, and puts every job over the state's written-contract threshold on paper first.

The deck permit line

Sunnyvale publishes its own sheet of work that needs no building permit, with painting and similar cosmetic work on it, a note that the list is not all-inclusive, and a reminder that exterior paint can need the Planning Division's approval on an Eichler or a Heritage District house. The state residential code fills in the rest: no application for an ordinary repair to a structure, never the cutting of a structural beam or a load-bearing support. Replacing boards, treads and a railing post, correcting flashing and refinishing are that; a deck or a balcony rebuilt from the frame, a new footprint or a replaced ledger is a permit, and we ask the Building Safety Division before a job like that and tell you what it said.

The Eichler guidelines, the Heritage District and the condos

Most of Sunnyvale's single-family streets have no association. The Eichler tracts follow the city's Eichler design guidelines, which care about the look of the house, so a deck or a railing visible from the street keeps the flush lines and the low profile, and a Heritage District porch is rebuilt to what was there. The condos and townhomes toward the Bay carry SB 326 and the apartment buildings SB 721; the decking, railing, flashing and membrane items the report flags are ours to scope for the board, and a structural member goes back to the engineer first.

Call 408-916-4022

Faster than anywhere else we serve: the office is downtown on Murphy Avenue, a few minutes from any Sunnyvale street. We answer in under three rings, give most deck repairs a range on the call from a photo, and the look is usually within days. Boards, a railing or a set of steps are often one visit; a frame the termites found waits for the pest company first.

Repair first. On an Eichler the low frame can be rebuilt on standoffs under the boards you have, and on a porch the posts and steps can be replaced one at a time; a sound frame under a tired surface is the usual Sunnyvale case. When the joists are eaten through, the ledger has let go or the deck has moved, we show you the wood and price both paths in writing; a new deck is a permit and often an engineer, and we say so before you choose.

Yes. We do the repairs an SB 721 report calls out on apartment buildings with three or more units, and the repairs the condominium and townhome associations toward the Bay need under SB 326: decking, joists, railings, flashing and waterproofing, scoped in writing for the owner or the board with photos for the re-inspection. If the report calls an element structural, it goes back to the engineer first. Our Sunnyvale SB 721 balcony inspection and repair page covers the inspection itself.

Not to replace boards, treads or a railing post, correct flashing or refinish; the city's own sheet exempts cosmetic work and the state code asks no application for an ordinary repair. A deck or a balcony rebuilt from the frame, a new footprint or a replaced ledger is a permit, exterior paint on an Eichler or a Heritage District house can need Planning's nod, and we ask the Building Safety Division before a job like that.

It depends on how much of the frame under a low deck is soft, how many boards the sun split and what the finish has to match. Text a photo of the worst board, the post base and the rail and you get a range on the call; after the look, a written scope with the frame, the boards, the hardware and the finish priced before anything is ordered. What you approve is what you pay.

Yes. Every Sunnyvale deck and balcony repair carries our one-year workmanship warranty in writing, done by Kaminskiy-certified, background checked technicians under California contractor License #1106209, bonded and insured.

Yes, when the crew knows the house. We rebuild the low frame on standoffs so it stops drinking from the sprinklers, replace the boards to the same width and reveal, cap the exposed beam ends so they read as original, keep the railing low and flush to the city's Eichler guidelines, and never drill the radiant slab blind. If rot has reached a beam that carries the roof, we tell you who needs to look at it first.

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.
