CDM Concord Masonry is a licensed masonry contractor serving Concord, CA homeowners with chimney repair, masonry restoration, and foundation work - operating out of our Concord location at 1300 Galaxy Way since 2023, with every inquiry answered within 1 business day.
A large portion of Concord homes were built between the 1940s and 1970s, and much of the original brick and block masonry on those properties has been absorbing and releasing moisture through dozens of wet-dry cycles. When mortar crumbles and white salt staining appears after the rains, our masonry restoration service repoints deteriorated joints, removes efflorescence, and seals the structure before another winter drives moisture deeper into the wall.
Concord sits near the Concord-Green Valley Fault, so older brick chimneys here face earthquake stress on top of the standard wear from hot summers and wet winters. Crumbling mortar joints, white staining on the exterior face, and smoke backing into the room when the fireplace is lit are the warning signs that a Concord chimney needs attention before the rainy season returns.
The clay soil common throughout Concord swells with winter rain and contracts in summer heat - and that annual movement is why so many homes here develop sticking doors, diagonal wall cracks, and floors that no longer sit level. Foundation repair in Concord accounts for this soil cycle, stabilizing the structure against the shifts that will keep coming every year.
On sloped Concord lots - particularly in neighborhoods toward the hillsides on the east side of the city - retaining walls manage the soil movement that heavy winter rains accelerate. A wall built without accounting for the local clay-heavy ground and seasonal wet-dry cycle will crack in a few years. We build walls designed for the conditions here.
Many Concord brick chimneys and garden walls from the 1950s and 1960s have never had their mortar touched since original construction. After 50 or more years of Concord summers and winters, that mortar is often well past its useful life. Tuckpointing removes the failing material and replaces it with fresh mortar matched to the existing joints before water finds its way behind the brick face.
Spalling bricks - where the face peels away in thin layers - are common on older Concord chimneys that have absorbed winter moisture and then baked through summer heat above 90 degrees, year after year. We replace damaged bricks with matched materials so the repair holds through the same seasonal cycle that caused the original problem.
Concord is the largest city in Contra Costa County, with a housing stock built heavily during the 1950s through 1970s. Those homes are now 50 to 70 years old, and many carry original chimneys, concrete flatwork, and masonry walls that have never been restored. The Mediterranean climate here works against masonry in two directions - hot, dry summers that regularly exceed 90 degrees bake and crack exterior surfaces, while the concentrated winter rains from November through March drive moisture into every opening. Add in the expansive clay soils underneath most Concord properties, which swell in the wet season and shrink as the ground dries out, and you have a property environment that applies stress to masonry from multiple angles.
The Concord-Green Valley Fault runs directly through the city. That means small earthquakes that most residents barely register can quietly widen cracks in chimneys and foundations over many years. A contractor without consistent Concord experience may overlook how much of the visible damage on a local home is the cumulative result of seismic stress layered on top of normal weathering - and that misread produces repairs that do not last. The City of Concord requires building permits for structural masonry work, and a contractor who is not familiar with that process either adds unnecessary delays or, worse, skips permits and leaves the homeowner with undocumented structural work that creates problems at resale.
We pull permits with the City of Concord Building Division for structural masonry work on a routine basis - it is a standard part of our process here, not something we navigate around. Concord has about 130,000 residents and is one of the more diverse cities in the East Bay, with an owner-occupancy rate of roughly 55%. That means most of our Concord clients are homeowners who are invested in the long-term condition of their property, not just the immediate fix.
The majority of homes we work on in Concord are single-story ranch houses built during the postwar era, with concrete driveways, brick chimneys, and stucco exteriors that show predictable wear patterns after a few decades. We work on properties near downtown and Todos Santos Plaza, out by the Concord Pavilion on the east side, and in newer subdivisions closer to the hills. The part of the city does not change the fundamentals: Concord clay soil and Concord summers affect every property here.
We also work regularly in Pleasant Hill, directly to the south, where the postwar housing stock and soil conditions closely mirror Concord. Homeowners in Walnut Creek to the southeast will also recognize the same clay soil challenges and Mediterranean climate wear patterns that drive demand for masonry work across this part of Contra Costa County.
When you call or reach out online, we ask a few basic questions - what you are seeing, how long it has been going on, and your address in Concord. We reply within 1 business day and schedule a free on-site visit at a time that works for you, including Saturdays.
We walk the structure with you, look at everything up close, and explain in plain terms what we found. If the scope requires a City of Concord permit, we tell you upfront and factor the review time into your timeline. You receive a written estimate that breaks down what is recommended and why - no vague totals, no pressure to decide immediately.
Once you approve the estimate, we submit the permit application to the City of Concord for any structural work that requires one. Permit approval typically adds a few business days before we can start. We confirm your start date and let you know what to clear from the work area beforehand.
Most Concord masonry jobs take one to three days on site, though foundation or retaining wall projects run longer. If a city inspector visit is required, we coordinate that directly. When the work is done, we walk you through the completed project and leave the site clean. You do not need to be home the whole time - we work independently and check in when needed.
We serve homeowners throughout Concord, CA and respond to every inquiry within 1 business day. Free estimates, licensed work, and permits handled when required by the City of Concord.
(925) 536-0971Concord is the largest city in Contra Costa County, home to about 130,000 residents with an owner-occupancy rate of roughly 55%. The city grew rapidly during the postwar suburban boom, and most of its established neighborhoods date from the 1950s through 1970s. Ranch-style single-family homes on modest lots - typically 6,000 to 8,000 square feet - are the dominant housing type, most with stucco exteriors, concrete driveways, and brick chimneys now several decades old. Older areas near downtown Todos Santos Plaza include housing from the 1940s and 1950s, while newer subdivisions closer to the hills were built in the 1990s and 2000s. Masonry repair needs vary significantly across these neighborhoods - older downtown blocks often require structural work, while newer areas on the outskirts tend to need cosmetic maintenance.
Concord is connected to San Francisco and Oakland via two BART stations, and the Concord Pavilion amphitheater is a landmark that most longtime residents know well. The view of Mount Diablo is visible from most of Concord and serves as a daily reference point for the whole region. The city is diverse and has a stable, long-term feel - families who have owned their homes for decades make up a meaningful share of our clients here. Nearby communities we also serve include Pleasant Hill to the south and Walnut Creek to the southeast, both sharing Concord's building era and climate conditions.
