Learn MoreTell us what you have been seeing - sticking doors, crumbling mortar, a cracked driveway. We ask a few quick questions, then schedule a free on-site assessment at a time that works for you. No commitment, no pressure. We respond within 1 business day, often the same day.
We come to you, inspect the problem from every angle, and walk you through what we found in plain language. You get a written estimate that lists exactly what work will be done, the materials we'll use, and the full cost. No verbal-only quotes, no surprise add-ons after you sign.
For structural jobs, we handle the permit application with the City of San Leandro so you do not have to navigate City Hall. Once the work is done, we walk you through the finished repair, hand over any warranty documentation, and make sure the site is clean. You will know what to watch for and how to reach us if anything comes up.
We hold an active California contractor license (C-29 Masonry) and carry full general liability and workers compensation coverage. You can verify our license on the CSLB website before signing anything.
We come to your property, inspect the actual problem, and give you a written estimate at no charge. You make the decision with full information - not under pressure from a call center rep working off photos.
We live and work in the East Bay. We know the soil conditions near the Hayward Fault, the age of local housing stock, and the permit process at City Hall. That local knowledge shows up in the quality of every repair.
Every job comes with written warranty documentation before we leave. Well-executed structural repairs using quality materials should hold for decades - we stand behind them and make it easy to reach us if anything comes up.

"We had a foundation crack that had been there for years - we kept putting it off. They came out, explained exactly what was causing it, and had the repair done in two days. The door that would not close properly finally closes again. Worth every dollar."
Marcus T., Oakland - Foundation repair
"The chimney mortar on our 1958 house was completely shot. They tuckpointed the whole stack and matched the mortar color better than I expected. Did not have to reschedule once - they worked around the rain and finished the week they promised."
Diane R., Alameda - Tuckpointing
"We needed a retaining wall on a sloped section of our backyard that kept washing out every winter. The crew built a solid block wall, handled the drainage behind it, and cleaned up the whole area when they were done. Two rainy seasons in and it is holding perfectly."
Carlos M., Hayward - Retaining wall construction
We respond within 1 business day - usually the same day. There is no obligation to move forward, and no charge for the estimate. After you submit, someone from our office will call to schedule a free on-site visit so we can see the problem in person before giving you a number.
(510) 738-1722San Leandro Masonry & Concrete is based in San Leandro and serves 12 communities across Alameda County and the surrounding East Bay. Our service area includes Oakland, Hayward, Berkeley, Fremont, and more. Most jobs can be scheduled within the same week of your estimate.
Bay Area winter rain soaks into aging mortar repeatedly over months, and even without a hard freeze, the wet-dry cycle gradually breaks it apart. Scheduling tuckpointing before the rainy season - not after - prevents a small maintenance job from becoming a water damage repair. The Brick Industry Association recommends inspecting mortar joints every five to ten years in coastal climates.
Concrete is strong and long-lasting but cracks over time when tree roots or clay soil shifts beneath it. Pavers flex with ground movement and are easier to repair section by section - a clear advantage in San Leandro where expansive clay soil is common. Individual pavers can be replaced without breaking up the whole surface.
After any noticeable earthquake and at the start of each rainy season. Walls that are leaning, have visible gaps in the block courses, or show rust staining (from rebar corrosion) need professional evaluation before the next heavy rain. A failing retaining wall becomes a slope failure problem very quickly in wet conditions.
Late spring through early fall - roughly May through October - gives mortar the dry, moderate conditions it needs to cure properly. Scheduling in September or October before the rainy season is especially smart. Mortar cured in wet conditions or extreme heat can crack prematurely, shortening the life of even a quality repair.
Tree roots grow toward moisture and find their way under concrete slabs, lifting sections from below. The result is uneven, cracked concrete that is both an eyesore and a trip hazard. In San Leandro's older neighborhoods, large street trees are one of the most common reasons homeowners need driveway and walkway repairs.
Tuckpointing done with the correct mortar mix should last 20 to 30 years. Foundation piering systems often carry 25-year warranties. Concrete block walls and stone masonry, properly built and sealed, hold up for decades with minimal maintenance. Longevity depends more on correct materials and installation than on price - and proper masonry restoration technique is what separates a 30-year repair from one that fails in five.
San Leandro Masonry & Concrete is a licensed and insured masonry contractor based in San Leandro, CA, serving 12 East Bay communities since 2017. We hold a California C-29 Masonry contractor license issued by the Contractors State License Board, which you can verify at any time on the CSLB website. Our crew has completed masonry projects across all 16 service categories - from foundation stabilization and chimney repair to stone veneer, outdoor kitchens, and retaining walls - on both postwar bungalows and larger hillside homes throughout Alameda County.
Learn more about our teamBulging walls, a leaning chimney, or a foundation that has shifted noticeably are not cosmetic problems - they are safety concerns. Do not wait for the next inspection cycle if you see active movement. Call a licensed contractor for an assessment before the next rain or seismic event.
Targeted repair is almost always cheaper than full replacement - but only if you catch the problem early. A chimney with 20 percent failed mortar is a repair job. A chimney with 70 percent failed mortar and shifted sections is a rebuild. Annual visual checks after winter and after any notable earthquake help you stay in the less-expensive category.
Look for a California C-29 license you can verify online, proof of insurance, and written estimates before work begins. The CSLB license check tool takes about 60 seconds and shows license status, type, and any filed complaints.

San Leandro is a fully built-out East Bay city of about 90,000 residents packed into roughly 15 square miles, bordered by Oakland to the north. Most of the city's homes were built between the 1940s and 1970s, which means aging concrete, original brick chimneys, and foundations that have spent decades absorbing the movement of Bay mud and expansive clay soil. From the flat postwar ranch homes of Washington Manor to the hillside split-levels of the Broadmoor district, we have worked on properties throughout the city.
Several San Leandro landmarks give the city its character - the San Leandro Marina along the bay, the Estudillo Estates neighborhood near downtown, and the San Leandro BART station that connects thousands of residents to Oakland and San Francisco each day. About half of the city's housing units are owner-occupied, according to the U.S. Census Bureau, and many of those homeowners have significant equity tied up in properties they plan to stay in - which is exactly the type of homeowner who takes masonry maintenance seriously.
San Leandro's clay soil expands and contracts with every wet season, tree roots from large street trees crack concrete driveways and walkways regularly, and winter storms drive water into aging mortar joints on chimneys and brick walls throughout the city. Whether your home is near the bay or up in the hills, San Leandro Masonry & Concrete has the local experience to diagnose and repair the specific masonry problems that East Bay homes face.
