Kaminskiy Care and Repair patches stucco cracks and chips and matches the existing texture so the repair blends in. Hairline cracks are cosmetic; widening or bulging ones deserve a call, and the quote is free either way. We serve Concord and the surrounding California communities.
Fifteen minutes from Walnut Creek. Sun-baked walls and buried weep screeds lead the Concord stucco list.
Concord stucco bakes. The 1960s and 1970s family homes of Ygnacio Valley and Walnut Country carry three-coat stucco over wood frame, with pop-out window sills and the weep screed buried under fifty years of lawn, and the hundred-degree afternoons open hairline cracks at every window corner while the sprinklers soften the bottom foot. We cut the cracks and fill them, re-lath the hollow sections, rebuild the sill caps, match the texture and the color, and get the grade back down where the wall can drain.
AFTERBEFOREEach of these is a patch, not a new wall, for a Kaminskiy-certified technician from our Walnut Creek office, fifteen minutes down Treat Boulevard. One look, one written scope, then the coats, each one cured.
Priced and on the calendar during the first call.
A written quote you approve before anyone drives out.
Three coats, each one cured, warranty in writing.
A one-year workmanship warranty, in writing, on every Concord stucco repair.
Heat and water, in that order. Concord sits on the warm side of the county, and hundred-degree afternoons shrink the wood framing and the stucco on it until the hairlines open at the window corners and the finish coat chalks to powder on the west wall. Then the November rain runs into those cracks, the sprinklers keep the bottom foot wet all summer, and the bond between the stucco and the lath lets go, which is the hollow sound under your hand. The clay under much of the Diablo Valley moves with the seasons too, and a wide crack that opens and closes by the month is the clay talking.
A fine crack you cannot fit a fingernail in is the wall breathing, and it is sealed and recoated so the rain stays out. A crack as wide as a pencil lead, a diagonal that starts at a window corner and keeps going, a crack that is wider at the top than the bottom, or a wall that is hollow across a stretch you can span with both arms is a repair. Call sooner about a crack that reopened after a patch, a stain on the drywall inside below it, or a sill that moves when you press it; a crack that follows the foundation line goes to an engineer before we touch it.
The loose stucco comes off down to the lath, and any lath that has rusted through is replaced over new paper. Then three coats: a scratch coat pressed into the lath and scored, a brown coat that brings the patch flush, and a finish coat floated to the texture around it. Each coat cures before the next, and in Concord's heat we keep a fresh coat damp so it cures instead of drying too fast and cracking. That is why the patch is a day of work spread across visits, and the scope says how many before we start.
Turn the sprinkler heads away from the house and swap the ones along the wall for drip. Pull the lawn and the planter soil down until you can see the metal weep screed at the bottom of the wall, because that is where water inside the stucco is meant to run out. Keep a coat of elastomeric or good exterior paint on the stucco so the hairlines are bridged before the rain, caulk where the stucco meets the window frames, and look at the west wall every fall. A cracked sill caught in October is a sill; the same sill in March is a wall.
Ranch houses with wide eaves and, on most of them, plywood or board siding, so a stucco call here is usually the garage front, a planter wall, a chimney chase or a later addition. The sun has chalked the finish on the west face, the bottom edge sits in sprinkler spray, and someone has filled the cracks with caulk that is now a shiny line down the wall. We cut out the caulk, patch properly in three coats and match a sixty-year-old texture; the wood walls belong on our Concord dry rot page.
1970s to 1990s homes on the open space, in full sun and the north wind, many with an association color scheme and some inside the 2025 fire zone. The stucco is three-coat on the older streets and runs over foam trim bands on the newest, and both crack at the window corners and chalk on the sunny faces; the foam trim chips at the corners and lets water in behind it. We patch the field, rebuild the chipped trim, match the scheme color from the association's book and photograph the wall before and after.
The stucco heart of Concord: 1960s and 1970s family homes with pop-out sills, garage jambs on the slab, pool yards and a sprinkler head aimed at every wall. The sills crack at their corners and go hollow, the bottom foot of the wall loses its bond where the spray hits, and the weep screed has been under the lawn since the first owner. We cut the soft sections back to sound lath, rebuild in three coats, recast the sill caps and dig the grade down so the wall drains again.
Call 925-302-5955 or text pictures of the crack, the sill and the bottom of the wall, with a tape or a coin in the shot for scale. Most Concord stucco repairs get a range on the call and a date for the look.
A technician taps out the hollow areas, measures the cracks, checks the sills, the corner beads and the weep screed, and photographs the texture and color. The scope lists each patch, the coats and visits it takes, the price, and whether the Building Division wants a permit for it.
Cracks cut and filled, soft sections taken back to sound lath and re-papered, then the scratch coat, the brown coat and the finish coat, each one cured before the next and kept damp through the Concord heat. Rushing a coat is how a patch cracks by spring, so we do not.
The finish is color matched or the patch is primed and painted to the wall or to the association's scheme, the rubble leaves with us, and the one-year workmanship warranty is on the invoice at the price you approved.
A small repair under a set amount can be done in California without a license when no permit is needed and nobody is employed to do it; a stucco patch cut back to the lath and built in three coats is past that line on most Concord walls. Kaminskiy Care and Repair carries License #1120648 with bond and insurance behind it, and the technicians on the wall are Kaminskiy-certified and background checked. Jobs over the state's written-contract threshold are on paper before the first coat.
Concord publishes a bulletin on the residential work that needs a permit, and it names decks, stairways, patio covers, re-roofs and windows, says the list is not complete, and has no line for stucco, siding or sills. The state residential code the city builds to asks no application for ordinary repairs to a structure, and exempts painting and similar finish work, so filling cracks, patching a section, recasting a sill cap and recoating are maintenance. Tearing off and re-lathing a large area, or re-stuccoing a wall, is a question for the Building Division, and we ask it before we price that job rather than guess.
Parts of Concord near the hills are in the very high fire hazard zone on the 2025 state map, where new construction has to meet the wildfire standard; a like-for-like stucco patch is a repair, not new construction, and stucco itself is a wall finish the standard accepts. Most of Concord has no association; Crystyl Ranch, Turtle Creek and some Clayton Valley streets do, and a patch painted to the scheme rarely needs a form, while a new color does. On the clay lots a crack that opens and closes with the seasons is movement, and we say so rather than sell a patch that will reopen.

Call 925-302-5955More than a single morning. The hollow stucco comes off to the lath and the patch goes back in three coats, scratch, brown and finish, with a cure between each, so the work lands on several visits a few days apart. In the summer heat we also keep a fresh coat damp so it cures instead of baking. The written scope tells you how many visits your wall takes before we start.
Yes, to the point that you have to look for it, and a repaint of that face hides it entirely. We float the finish coat to match the texture around it, from the heavy dash on a 1960s Walnut Country house to the smoother finish on a Crystyl Ranch home, and match the color in daylight. A fresh patch reads a shade different for a few weeks while it cures, and we say so up front.
Not about the fine ones at the window corners, which are the heat working on the framing; they get sealed and recoated so the rain stays out. Worry about a crack that widens, one that runs diagonally off a corner and keeps going, one that reopened after a patch, or a stretch of wall that sounds hollow. Those get a look, and a crack that follows the foundation goes to an engineer before we patch it.
No. EIFS is a foam-and-mesh wall system, and a patch that ignores its drainage details traps water in the wall. If your wall is EIFS we tell you on the call and point you to the system's certified installer. Conventional three-coat stucco over lath is ours, and so is the foam trim on a stucco wall, which is a different thing from EIFS.
It depends on how many patches, how big, whether the lath comes out, how high the wall is and what the finish takes to match. Send photos with a coin in the frame and the call gives you a range; the look gives you a written scope with every patch, coat and visit priced before a saw touches the wall. The price on the scope is the price on the invoice.
Yes. A one-year workmanship warranty is in writing on every Concord stucco repair, and the work is done by Kaminskiy-certified, background-checked technicians under California contractor License #1120648, bonded and insured.
Because it has been wet for years. The weep screed at the bottom of a Concord wall is meant to sit above the dirt and let water out of the stucco, and on most 1960s and 1970s houses the lawn and the planters have grown up over it while a sprinkler hits the same spot twice a day. The bond to the lath fails and the wall goes hollow. We cut that section back to sound lath, rebuild it in three coats and dig the grade down below the screed so it stays dry.
