CDM Concord Masonry is a licensed masonry contractor serving San Ramon, CA with outdoor kitchen construction, retaining wall installation, and driveway paver work - built for the hillside lots, HOA-governed communities, and clay soil conditions that define this part of Contra Costa County. Every inquiry is answered within 1 business day.

San Ramon sits in a valley where outdoor entertaining season runs from April through October - making a built-in outdoor kitchen a genuinely useful addition, not just a luxury. Our outdoor kitchen masonry builds permanent structures from brick, stone, or block that are properly footed for San Ramon's expansive clay soil, so the countertop stays level and the mortar joints stay tight through years of wet-dry soil cycles.
San Ramon has more hillside and graded lots than most East Bay cities - a direct result of its location between the Mount Diablo foothills and the Diablo Range. Those sloped lots need retaining walls that are engineered for drainage, not just stacked up and hoped for. We build walls with proper footings and drainage systems behind them so winter runoff does not build pressure that pushes the wall forward over time.
The majority of San Ramon homes were built between 1980 and 2005, which means original concrete driveways are reaching the 20-to-40-year mark where clay-soil movement and surface wear become visible problems. Pavers installed on a properly compacted gravel base handle the seasonal ground movement here better than poured concrete slabs, which is why replacement paver projects are one of the most requested jobs across San Ramon neighborhoods.
Tiered yards and sloped entries are common on San Ramon properties built into graded hillside lots, and original concrete walkways on these grades are prone to settling unevenly as the soil below shifts through wet and dry seasons. We build replacement walkways designed for these conditions - with subbase work and joint spacing that accounts for how San Ramon soil behaves on a slope year after year.
Stucco-clad homes from the 1980s and 1990s are the dominant building type in San Ramon, and stone veneer is one of the most requested upgrades when homeowners want to update the look of a foundation wall, outdoor kitchen surround, or front entrance without a full rebuild. We select veneer materials that hold up to San Ramon's combination of intense summer heat and occasional winter frost at the foothills.
HOA-governed planned communities throughout San Ramon - from Crow Canyon to Twin Creeks - often have older block walls along property lines and shared borders that are showing mortar joint failure after 30-plus years of clay-soil movement. We build and repair block walls to the material and finish standards that HOA architectural reviews in these neighborhoods typically require.
San Ramon grew from a small community to a city of over 84,000 people in just a few decades, and most of its housing stock reflects that rapid suburban build-out from the 1980s through the early 2000s. That timeline means the bulk of original concrete flatwork, retaining walls, and exterior masonry throughout the city is now 20 to 40 years old - exactly the age when clay-soil movement, UV degradation, and seasonal stress accumulate into visible failures. The valley location traps summer heat, with temperatures regularly reaching the mid-to-upper 90s Fahrenheit and occasionally topping 100 degrees. That heat accelerates the breakdown of mortar joints, caulk, and concrete surfaces in ways that coastal homeowners simply do not deal with.
The terrain adds another layer. San Ramon sits between two hill ranges, and many residential lots were graded or cut into slopes during development. Retaining walls, tiered yards, and sloped driveways are common features that put ongoing stress on concrete and masonry foundations as the expansive clay soil beneath them swells with winter rain and contracts through the dry summer. A contractor who has not worked on San Ramon hillside lots may not account for the drainage requirements that determine whether a retaining wall stands firm for 20 years or starts leaning after two rainy seasons. Getting the drainage right behind the wall is as important as the wall itself.
We pull permits for structural masonry work through the City of San Ramon and are familiar with the HOA architectural review process that governs exterior work in planned communities like Gale Ranch, Crow Canyon, and Twin Creeks. Many of the outdoor kitchen and retaining wall projects we do in San Ramon require HOA sign-off before a city permit can even be submitted, so we build that timeline into the project schedule from the first conversation.
We work on homes throughout San Ramon - from the hillside properties off Bollinger Canyon Road and the foothills communities with views toward Bishop Ranch, to the flatter subdivisions near the City Center. The graded lots in the eastern and northern parts of the city come with different drainage requirements than the flatter lots near Dublin Canyon Road, and that difference shapes how we design the base and drainage for every retaining wall and flatwork project.
Our service area covers the full Tri-Valley region. We also serve homeowners in Walnut Creek to the north, and we regularly work in Danville just to the south, where similar hillside lot conditions and affluent planned communities create the same type of masonry work we do here.
Reach out by phone or through the contact form and we will respond within 1 business day. Be ready to describe what you want to build, your general location in San Ramon, and whether your neighborhood has an HOA - that last detail affects how we plan the project timeline from the start.
We visit your property to assess the slope, soil conditions, and any existing structures before giving you a written estimate - because outdoor kitchen and retaining wall pricing in San Ramon depends heavily on what is already on the lot. No phone quotes for work of this scope.
We submit the city permit application and, where required, the HOA architectural review request before scheduling construction. Permit processing typically takes one to three weeks; HOA review can add another two to four weeks in communities like Gale Ranch and Crow Canyon. You do not need to manage this paperwork.
The crew completes the work in stages - foundation and footing first, then the masonry structure, then finishing surfaces. At completion, we walk through the finished project with you and confirm the city inspection has been signed off before we consider the job done.
We serve San Ramon homeowners from Crow Canyon to Gale Ranch. Call us or submit the form and we will get back to you within 1 business day with a clear next step.
(925) 536-0971San Ramon is a city of over 84,000 people in Contra Costa County, positioned in the Tri-Valley between the Mount Diablo foothills to the north and the Diablo Range to the east. The city grew rapidly during the suburban build-out of the 1980s and 1990s, and today most of its residential neighborhoods date from that era - planned communities like Gale Ranch, Crow Canyon, and Twin Creeks that are recognizable by their stucco-clad homes, tiered lots, and active HOAs. The economic center of the city is Bishop Ranch, one of the largest office parks in the western United States and home to major employers including Chevron's U.S. headquarters. The combination of high homeownership rates, high incomes, and well-established neighborhoods means most San Ramon homeowners invest seriously in their properties.
The valley setting gives San Ramon one of the more demanding climates in the East Bay for exterior masonry - intense summer heat from June through September, concentrated winter rainfall from November through March, and the expansive clay soils that underlie most of the city. Homeowners on hillside lots near the foothills deal with runoff and drainage challenges that flat-lot neighborhoods do not face at the same level. We also serve homeowners in Walnut Creek to the north, where the Tri-Valley transitions into the more established neighborhoods of central Contra Costa County with their own mix of mid-century homes and newer construction.
