Martinez Concrete & Masonry is a masonry contractor serving Martinez, CA, with expertise in foundation repair, chimney repair, and masonry restoration. We have served homeowners throughout Martinez since 2016, and we know how older homes here - from craftsman bungalows near downtown to postwar ranch homes in the hillsides - respond to this area's clay soils and wet winters.
Martinez has some of the oldest homes in Contra Costa County, and their brick chimneys, retaining walls, and exterior masonry surfaces have been through decades of wet winters and dry summers. When mortar crumbles or surfaces spall, the damage spreads fast - especially on pre-war homes built with softer lime mortar. Learn more about our masonry restoration services and how we match repair materials to your home's original construction.
Most of Martinez sits on expansive clay soil that swells in the winter rains and shrinks again in the dry summer - and that seasonal movement is the leading reason foundations crack and settle here. Homes built before 1960, which make up a large share of Martinez's housing stock, are especially prone to accumulated foundation movement. We assess, stabilize, and repair foundations with the local soil cycle in mind.
A lot of Martinez homes still have their original brick chimneys, some dating back to the early 1900s. The mortar on those older chimneys has been through many wet seasons, and seismic activity near the Concord Fault adds stress that doesn't show up from the ground. We inspect and repair chimneys so you know your fireplace is safe before the first cold night of the year.
The hillside streets above downtown Martinez are common territory for us. Sloped lots accumulate drainage problems over time, and the clay soils here push against retaining walls with every wet season. We build retaining walls designed for local soil conditions - with footings deep enough to stay stable through the seasonal wet-dry cycle that defines this area.
Homes near the Carquinez Strait face constant marine air exposure, which shortens mortar life compared to properties further inland. When mortar joints open up, the wet seasons work water into the wall quickly. We grind out the failing joints and pack them with mortar matched to your home's original mix - important on pre-war homes where mismatched mortar can crack the surrounding brick.
Martinez's clay soils and seismic risk both factor into how a block wall needs to be built here. We dig footings deep enough to sit below the zone where soil moves seasonally, and we reinforce wall cores with steel - as the City of Martinez Building Division requires for walls above certain heights. The result is a wall that holds up to what this area actually throws at it.
Martinez was incorporated in 1876, and a large share of its homes were built before 1980. Victorian-era houses, craftsman bungalows from the early 1900s, and postwar ranch homes from the 1950s and 1960s all sit on the same expansive clay soil - soil that swells when it absorbs winter rain and shrinks again in the dry summer. That push-and-pull is the leading cause of foundation cracking, retaining wall movement, and mortar failure in this city. A contractor who does not account for local soil behavior will give you a repair that fails in the same way for the same reasons.
On top of the soil conditions, Martinez sits near active fault systems including the Concord-Green Valley Fault. Seismic forces crack foundations, shift chimney liners, and loosen mortar joints in ways that are not always visible from the street. And the city's Mediterranean climate - wet from November through March, then hot and dry through the summer - creates a seasonal stress cycle that older masonry in particular was not always built to handle. Knowing these conditions is not background information. It is the difference between a repair that lasts and one that starts failing before the next wet season.
Our crew has been pulling permits through the City of Martinez Building Division regularly, and we know what that process looks like - how long approvals typically take, what inspectors check at each stage, and how to get structural masonry work through review without delays. That familiarity with the local permit office saves our customers real time on every job.
We work on homes throughout Martinez - from the Victorian-era streets near downtown to the hillside lots above the city and the ranch homes on the east side. We know that a pre-war craftsman bungalow near Alhambra Avenue needs different mortar than a 1960s tract home, and that a sloped lot in the hills above the John Muir National Historic Site drains differently than a flat lot near the Marina. That on-the-ground familiarity shows up in the work.
We also serve homeowners in neighboring areas close to Martinez. If you're in Concord or Benicia, we work in those communities regularly and can serve you just as well as we do here at home.
We respond to all estimate requests within 1 business day. On the call, we ask a few basic questions about what you're seeing - how long it's been going on and whether there's been any prior work on the area. That helps us show up to your property prepared rather than starting from zero.
We walk the property with you, look at the damage, and explain what we're seeing in plain terms. We'll also tell you upfront whether a City of Martinez permit is required for the work - no surprises mid-project. Estimates are free and written, so you know exactly what the job covers.
Once you approve the estimate, we pull any required permits and get on the calendar. Most masonry jobs in Martinez take one to three days. You don't need to be home for every hour, but we'll let you know if there's a specific point where we need you on-site.
When the work is complete, we walk the finished job with you, answer questions, and go over any curing or maintenance steps. If a city inspector needs to sign off on permitted work, we coordinate that - you don't have to manage the building department yourself.

The city carries visible history in its architecture - the streets near downtown include Victorian-era houses and craftsman bungalows built between the 1880s and 1920s, while the hillsides and eastern parts of the city shift to postwar ranch homes from the 1950s and 1960s. That mix of building ages means the masonry needs across Martinez vary quite a bit from one block to the next. The city sits along the Carquinez Strait and Interstate 680, making it a practical home base for Bay Area commuters who put down real roots here. The city of Martinez has a homeownership profile that reflects a community where people invest in their properties for the long term.
