Door Repair in Sunnyvale

Sunnyvale is a city of 1950s and 1960s ranch houses and Eichlers, with original doors, walls of sliding glass and frames that the sprinklers have soaked for decades. Our office is on Murphy Avenue; we rehang, rebuild and install, usually the same week.

THE SUNNYVALE DOOR GUIDE

Know your door before
you call anyone

Why Sunnyvale doors fail

Age, water and clay. Most Sunnyvale homes went up in the 1950s and 1960s, so their doors, frames and sliders are well past sixty. Sprinklers and winter rain soak the frames at the threshold and rot them. And the valley clay swells and shrinks with the seasons, so doors bind in one season and rattle in the next.

Repair or replace?

In Sunnyvale a door that sticks or drags usually needs its frame trued, its wheels or hinges replaced and its seals renewed, not a new door. When the slab is split or rotted through, we install the one you choose, and we tell you which on the call.

Do I need a permit?

Not for a repair: a rehang, a rebuilt frame or new hardware are ordinary repairs. For a new exterior door we check Sunnyvale's rule for your address before you buy it; a larger opening always takes a permit, and an Eichler front follows the city's Eichler guidelines.

Eichler doors

Eichlers have glass walls, sliders to the yard and plain, flush front doors. Their sliders fail at the wheels and the track, which are fixable, and a new front door should keep the flush Eichler look to fit the city's guidelines.

SUNNYVALE, SOUTH TO NORTH

Where the house sits decides
what the door does

Our office is on Murphy Avenue in Sunnyvale. Kaminskiy has repaired and hung doors here since 2005.
THE SOUTH AND WEST

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

Ranch homes and Eichlers with original sliders and entry doors. We get sliders rolling on new wheels, rehang entry doors and rebuild frames rotted at the threshold.

THE MIDDLE OF TOWN

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

The oldest houses in town, some from the 1900s to the 1930s, beside 1950s tracts. We save original doors, rebuild frames and fit new hardware to old doors.

THE NORTH SIDE

Lakewood, San Miguel, Fair Oaks

Compact 1950s homes with builder doors. We swap hollow-core doors for solid ones, rehang entry doors and fix garage-to-house doors so they close on their own.

WHAT A VISIT LOOKS LIKE

One call, priced
before we come

01Call, or text a photo

A photo of the dragging slider or the soft threshold is enough. We work out the Sunnyvale price on that call and put it in writing before a visit is booked.

02One visit, truck stocked

Shims, hinge sets, strikes, slider wheels, weatherstrip, jamb stock and the common locksets leave Murphy Avenue with the technician, so most Sunnyvale repairs are done on the first trip.

03Your door, hung right

Measuring comes first, so the door you order fits the opening and swings the right way. Then the frame is trued and the door you bought is hung in it, plumb and sealed.

04Clean up, warranty in writing

The old slab, the cut casing and the packaging go in the truck, not your bin, and the paperwork you keep carries the one-year workmanship warranty in writing.

We install doors, we do not sell them: you buy the door, we measure for it and hang it. Not our lane: glass replacement, garage doors and commercial automatic doors. If that is what you need, we tell you on the call.
RULES WORTH KNOWING

Permits, the garage-to-house door
and HOAs, in plain words

Permits

Rehanging a door, rebuilding a frame, a new slab or new hardware are ordinary repairs that need no permit. Sunnyvale does not publish a door-swap rule we could read, so we check with the city for your address before you buy a new exterior door, and an enlarged opening takes a permit.

The garage-to-house door

California's residential code wants the door between the garage and the house to be solid wood or steel at least 1-3/8 inches thick, or rated for 20 minutes, and to close and latch on its own. Many older homes have a hollow-core door there or a closer that quit; we install the right door and the closer.

HOAs and historic homes

Most of Sunnyvale has no association. The Eichler tracts follow the city's Eichler design guidelines, which care about the look of the front, so a new entry door there should keep the Eichler lines. A repair that matches needs nothing.

GOOD QUESTIONS

Sunnyvale door questions,
answered

Can't find your answer? Call 408-916-4022 and ask us anything.

Call 408-916-4022

Text a photo or call and the repair is priced then and there, and most Sunnyvale doors get a slot within days. One trip covers a rehang, a frame rebuild, new weatherstrip or a lock swap, since the technician already carries the parts.

Usually, yes. Original Eichler sliders drag because their wheels and tracks wear out. We fit new rollers, true and clean the track and reset the latch, so a sixty-year-old slider rolls with one finger.

Small jobs and big jobs. Resetting a strike or rehanging a sagging ranch door is quick. Rebuilding a threshold the sprinklers rotted, or hanging the new prehung door you bought, takes the better part of a visit. Describe the door, or send a photo, and the Sunnyvale price is yours on the call, in writing, before it goes on the schedule.

Yes. A hollow-core door passes almost every sound. We swap it for a solid-core door, add a sweep and seal the stop, which cuts most of the noise from the hall.

We install, and you buy. Pick the door at a home center or a door shop, after we have measured the opening and told you the size and swing to ask for. The frame gets fixed, the door gets hung, sealed and trimmed, and the hardware goes on. Prehung or slab, interior or front, Eichler flush or paneled.

Yes. Prehung or slab, it goes in. Send a photo of the label, or tell us the width, height and whether it is left or right handed, and the install is priced on that call. If the Sunnyvale frame needs rot cut out before the door arrives, we tell you then, not on the day.

Not to repair one. For a new exterior door we check the city rule for your address before you buy it; a larger opening always takes a permit. In an Eichler tract, a new front door should also follow the Eichler guidelines.

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