Lafayette Concrete & Masonry is a masonry contractor serving Martinez, CA with foundation repair, retaining wall construction, and chimney repair - and we have extensive experience on the Victorian, craftsman, and postwar ranch homes common throughout this city. We respond within 1 business day.

Martinez homes built in the 1950s and 1960s sit on foundations that were never designed for the expansive clay soil movement that happens here every wet season. Our foundation repair work addresses the root cause - drainage and soil pressure - not just the visible crack in the concrete.
The hillside streets north and east of downtown Martinez put serious lateral pressure on retaining walls every time the soil gets saturated. We build and replace walls with drainage gravel and perforated pipe behind them - which is the detail that separates a wall that lasts from one that leans and fails within a decade.
Many of Martinez's older homes have brick chimneys that have never had the mortar joints repointed. After decades of wet winters and dry summers, those joints have opened up enough to let water into the chimney chase and into the wall framing below. We inspect, repoint, and crown-repair before small leaks become framing damage.
Martinez's Victorian and craftsman homes were built with softer, lime-based mortars that need to be matched carefully during repairs. Using modern Portland cement on these older walls damages the surrounding brick rather than holding it. We match mortar type to the original construction so restored sections hold up long-term.
Postwar ranch homes throughout Martinez commonly have concrete block property walls and raised planters that are now 60 to 70 years old. When clay soil movement causes these walls to crack or shift, we rebuild them with reinforcement and drainage that matches current Contra Costa County standards.
Spalling bricks on garden walls, front steps, and exterior features are a regular sight in Martinez's older neighborhoods. We source brick that matches the original size and color as closely as possible so repairs do not stand out - which matters on the historic homes near downtown that draw buyers specifically for their original character.
Martinez was incorporated in 1876, and a large share of its homes were built before 1980. That age alone creates a steady demand for masonry work - but the specific challenge here is the combination of old construction and difficult soil. Most of the city sits on expansive clay that swells in the wet season and contracts in the dry heat of summer. That movement is slow and invisible, but it adds up over decades, and homes built in the 1950s and 1960s that were never properly drained are showing the consequences now in the form of foundation cracks, leaning retaining walls, and failing chimney mortar.
The climate adds seasonal pressure on top of that. Martinez winters bring heavy rain from November through March, and the city's proximity to the Carquinez Strait means moisture stays in the air longer than it does further inland. That sustained moisture penetrates open mortar joints and cracks, and when overnight temperatures dip below freezing - which does happen several times each winter, especially on hillside properties - water that has worked its way into masonry expands as it freezes and widens those openings. A masonry contractor who does not account for both the soil conditions and the seasonal moisture cycle here will produce repairs that fail faster than the original work did.
Our crew works throughout Martinez regularly and pulls permits through the City of Martinez Building Division for structural masonry jobs that require one. We are familiar with what the city requires for retaining walls, foundation repairs, and chimney work - and we handle the paperwork and inspection scheduling so the project stays on track.
Martinez is a city of varied terrain. The streets near the Martinez Marina and along the Carquinez Strait sit at low elevation where drainage from the surrounding hills collects. The hillside neighborhoods above Alhambra Avenue climb steeply and deal with erosion, runoff, and retaining wall stress that flatland properties do not face. The historic homes near downtown, many of which back up to the area around the John Muir National Historic Site, are often the oldest structures we work on, and they require more careful material matching than newer construction.
We also serve homeowners in nearby El Cerrito and Concord, both of which share Martinez's mix of older housing stock and clay soil challenges.
Call or use the form on this page and we will get back to you within 1 business day to set up a free on-site visit. We do not quote masonry jobs from photos - too much depends on what we find when we look at the soil, drainage, and existing structure in person.
One of our crew leads walks the job with you - no charge, no commitment. We look at the scope, check for drainage or soil issues that affect the repair, and give you a written estimate the same day or within 24 hours. This is also where we tell you whether a permit is needed.
We pull permits if needed and begin work on the agreed start date. Most repair jobs in Martinez are completed in one to three days. Larger projects like full retaining wall replacements on hillside lots take five to seven days of on-site work, with permit review periods handled beforehand.
When the work is done, we clean up the site completely and walk through the finished job with you. If the work required a city inspection, we schedule it and confirm the permit is closed out before we consider the project finished.
We serve all of Martinez - from the hillside streets above downtown to the neighborhoods near the Marina. No travel fees, no commitment required.
(925) 298-0709Martinez is the county seat of Contra Costa County, incorporated in 1876 and home to about 38,000 residents. The city sits along the Carquinez Strait at the northern edge of the county and is known for a mix of Victorian-era homes near its historic downtown, craftsman bungalows built in the early 1900s, and large postwar neighborhoods of ranch-style homes that went up through the 1960s. This range of building ages - from 100-year-old wood-framed Victorians to 60-year-old stucco ranches - means the city's housing stock regularly needs both specialized historic repair work and more routine concrete and masonry maintenance. Homeownership rates in Martinez are relatively high at around 60 percent, and median home values in the $600,000 to $650,000 range reflect the investment most residents have in their properties.
The city has distinct character depending on which part you are in. Downtown Martinez, along Alhambra Avenue, has a dense concentration of historic buildings and one of the most recognized collections of Victorian architecture in Contra Costa County. The hillside neighborhoods to the north and east climb steeply and offer views of the Carquinez Strait, but they also come with sloped lots, retaining walls, and drainage challenges that are part of daily life for homeowners there. Nearby Pleasant Hill and Walnut Creek share similar soil conditions and housing ages, and we serve both communities regularly.
