Learn MoreReach out by phone or through our contact form. We ask a few basic questions - what you are seeing, where the damage is, and how old your home is. We respond within 1 business day and schedule a free on-site visit at a time that works for you.
A contractor comes to your property, looks at the damage up close, and explains exactly what is going on. You get a written estimate that breaks down the work, the materials, and the cost - along with a clear answer on whether a city permit is needed. No pressure, no vague numbers.
Once you approve the estimate, we pull any required permits, schedule the crew, and get the job done. When the work is finished, we walk you through everything, hand over your warranty documents, and coordinate any required city inspection before we close the job out.
We hold a valid California Contractors State License Board license for masonry and concrete work. Every crew member on your property is covered by general liability insurance and workers compensation - so you are never exposed if something unexpected happens.
We come to your property, look at the actual damage, and give you a written estimate before you commit to anything. You will know exactly what the work involves and what it costs. No phone guesses, no hidden line items after the job starts.
We have been working on Martinez homes since 2016 and know the local soil conditions, permit requirements, and building stock well. When you call us, you are talking to people who work in your city every week - not a call center routing jobs to whoever is available.
We walk you through the warranty document before you sign anything. You will know what is covered, for how long, and what to do if you ever need to call us back. For permitted jobs, the city inspection creates an independent record that protects you if you sell your home.

"We had diagonal cracks in two door frames and were worried about foundation movement. The crew came out, explained exactly what was happening with the clay soil under our house, and completed the repair in two days. Everything is level and the cracks have not come back."
David R., Martinez - Foundation repair
"Our chimney had not been touched since we bought the house in 2001. After an earthquake I noticed some loose bricks near the crown. The tuckpointing work was clean, fast, and matched our original mortar color better than I expected. Used the fireplace that same fall."
Sandra M., Concord - Tuckpointing
"The retaining wall on our hillside lot had been leaning for years. The new block wall they built is solid, properly drained, and looks much better than what we had. They pulled the permit and handled the city inspection without us having to do anything."

Water is the primary cause of masonry failure. It enters through mortar joints, expands when it freezes, and slowly breaks apart brick and stone from the inside. In Martinez, wet winters followed by dry summers create repeated moisture cycles that accelerate this process on any unprotected masonry surface.
Yes. The Concord Fault runs through Contra Costa County, and even moderate shaking can crack chimney liners and loosen mortar joints in ways that are not visible from the ground. The Chimney Safety Institute of America recommends an inspection after any noticeable seismic event.
Using high-strength modern cement mortar on older, softer brick forces stress into the bricks instead of the mortar. The bricks crack and spall while the mortar stays intact. Homes built before the 1950s - and there are many in Martinez - need a softer lime-compatible mortar to protect the original brickwork.
Late spring through early fall is the best window in Martinez - typically April through October. Fresh mortar needs dry conditions to cure, and the rainy season runs November through March. Scheduling repairs before the wet season arrives protects the new mortar and prevents small damage from worsening over winter.
Permits exist for your benefit, not just the contractor's. A permitted repair means a city inspector independently verifies the work at key stages. If you sell your home, permitted structural work is documented and defensible. Unpermitted repairs can complicate a sale or void insurance claims. The City of Martinez Building Division handles local permits.
Expansive clay soil swells when it rains and shrinks during dry summers. That seasonal movement pushes against foundations, cracks concrete slabs, and destabilizes retaining walls year after year. Most of Martinez sits on clay-heavy soil, which is why foundation and masonry problems are common here even in well-maintained homes.

Since 2016, we have completed masonry and concrete projects across 16 service categories for homeowners and property owners throughout the East Bay.

Learn more about our company and our approach to masonry work in Martinez.Cracks that are growing, bricks that are shifting or bulging outward, and any sign of water intrusion after rain warrant a prompt call. Worn mortar joints that are not yet letting water in can usually be scheduled a few weeks out without the problem worsening significantly.
Water entering open joints or cracks will freeze and expand during cold snaps, making the damage significantly worse by spring. A small repointing job in October can turn into a full chimney section rebuild by March if the wet season gets inside first.
Ask directly what mortar type they plan to use and whether they have assessed your original mortar strength. For homes built before the 1950s, the answer should reference lime-compatible mortar. If they cannot answer this question, that is a signal to keep looking.
The Brick Industry Association publishes technical resources on masonry maintenance that are worth reviewing if you want to understand your options before getting estimates. When you are ready to talk through your specific situation, call (925) 316-0136 or send us a message.
Martinez is the county seat of Contra Costa County, with roughly 38,000 residents and a homeownership rate around 60%. The city was incorporated in 1876, and a large share of its housing stock was built before 1980 - including Victorian-era homes near downtown, craftsman bungalows from the early 1900s, and the postwar ranch homes that fill the neighborhoods east of Alhambra Avenue. Homes this age are overdue for masonry attention in many cases.
The city has distinct landmarks that most locals know well. The John Muir National Historic Site in the Alhambra Valley draws visitors to one of the city's most recognized addresses. The Martinez Marina sits on the Carquinez Strait at the northern edge of town, and the streets closest to the water see higher moisture exposure that accelerates mortar breakdown. Hillside lots above downtown - particularly on the streets north and east of downtown - come with sloped yards, terraced gardens, and retaining walls that need regular attention to manage drainage and soil movement.
Martinez sits on expansive clay soil that swells in the wet season and shrinks during dry summers, putting steady stress on foundations, concrete flatwork, and masonry walls throughout the city. Our crew works on homes in every Martinez neighborhood, from the Victorian blocks near the city hall district to the ranch homes on the hillside streets - and we know the difference between what a 1910 craftsman bungalow needs and what a 1960s ranch home requires, because the work is genuinely different.
