A cracked, uneven, or missing sidewalk is a safety hazard and a curb-appeal problem. We build concrete sidewalks that pass town inspection, handle Marin winters, and stay safe for foot traffic for decades.

Concrete sidewalk building in San Anselmo means removing whatever is currently in place, preparing a stable compacted base underneath, and pouring fresh concrete that hardens into a safe, durable walking surface - most residential sidewalk projects take one to three days on-site, followed by about a week of curing before normal use.
A lot of the sidewalks in San Anselmo are original concrete from the 1940s, 1950s, and 1960s. At that age, cracking, heaving, and surface spalling are not cosmetic issues - they are structural problems and trip hazards. Replacing a badly deteriorated sidewalk is almost always a better value than repeated patching.
If the path you are replacing connects to your driveway or front approach, our concrete driveway building service covers those adjacent surfaces so you end up with a unified, consistent finish rather than two separate projects done years apart.
If one slab has risen higher than the one next to it, creating a step or lip that was not there before, the ground underneath has shifted. In San Anselmo, this is often caused by clay soil expanding after the rainy season, or by tree roots pushing up from below. It is a trip hazard that tends to get worse, not better.
Hairline cracks are normal in older concrete. Cracks you can fit a finger into - especially ones running all the way across a slab - mean the structural integrity is compromised. At that point, patching rarely holds for long, and full replacement is usually the more cost-effective path.
A sidewalk that holds standing water after a storm has either settled unevenly or was never graded correctly. In a town that gets heavy winter rain, pooling water speeds up surface deterioration and creates a slipping hazard during the wet months.
When the top layer of concrete starts to flake off in patches - called spalling - the surface becomes uneven and harder to walk on safely. This kind of wear is common on sidewalks that are 40 or more years old, which describes a large share of the concrete in San Anselmo's older neighborhoods.
We handle the full scope of residential sidewalk work: demolition of the existing surface, root assessment, base preparation, the concrete pour, and the finish. We assess root proximity before every pour in San Anselmo - it is one of the most common reasons sidewalks fail prematurely in this area - and we talk through options honestly when roots pose a real risk. We do not just pour over the problem.
For finish, we typically recommend a broom finish for residential sidewalks in Marin County. A smooth trowel finish looks clean but can become slippery in wet conditions, and San Anselmo gets foggy mornings and heavy winter rain. A textured broom finish gives better footing year-round. We discuss the options at the estimate stage so you make that decision before pour day.
If your project connects to a front entry or requires steps down from the sidewalk to your yard, our concrete steps construction service can be scoped alongside the sidewalk for a single, coordinated project. And if the replacement surfaces extend to your front approach, concrete driveway building covers those areas in the same job scope.
Suits homeowners with dirt, gravel, or no formal path between the street and the front door who want a permanent, low-maintenance surface.
Suits homeowners with an existing sidewalk that is cracked, heaved, or deteriorated beyond the point where patching makes financial sense.
Suits homeowners with isolated problem slabs - one or two lifted sections - where replacing just the damaged portion is practical and cost-effective.
Suits homeowners whose front path involves grade changes requiring steps to connect the sidewalk level to the front door or yard level.
San Anselmo's residential streets are lined with mature oaks, redwoods, and ornamental trees whose roots can run under sidewalks and cause heaving within a few years of installation if the issue is not assessed first. San Anselmo also sits on clay-heavy soils in the Ross Valley that expand when wet and shrink when dry, putting stress on concrete from below every single season. A sidewalk built without accounting for both of those conditions will not hold up the way it should.
The rainy season here runs November through March, with about 40 inches of annual rainfall, which means the installation window is narrower than most homeowners expect. Getting on a contractor's schedule by April or May gives you the best conditions for curing and the most flexibility in scheduling. The Town of San Anselmo also requires permits for new sidewalk work and inspects completed jobs - we pull the permit and manage the inspection process so you do not have to.
We work on properties across the Ross Valley and beyond, including older residential streets in Fairfax, hillside neighborhoods in Larkspur, and homes throughout San Rafael. The same soil and drainage challenges show up across Marin County, and we bring the same site-specific approach to every job.
We visit the property to assess the existing conditions - root proximity, slope, access, and scope of demolition needed. You receive a written estimate that covers every step from demo to cleanup. We reply to all new inquiries within one business day.
For most sidewalk projects in San Anselmo, we apply for a permit through the Town's Community Development Department before any work begins. This step adds a few days to the timeline but is required, and we handle it for you. Once the permit is in hand, we lock in your start date.
We remove the old concrete or existing material, haul it away, grade and compact the subgrade, and lay the gravel base. This preparation step determines how well the finished sidewalk holds up - we do not rush it to get to the pour faster.
We pour the concrete, cut control joints, apply the surface finish, and ask you to stay off the surface for at least 24 to 48 hours. Full cure takes about a week. For permitted work, we schedule the town inspection and you receive the sign-off before the project is fully closed.
We reply within one business day. All estimates are free, written, and completed in person after a site visit.
(415) 604-1678San Anselmo's mature tree canopy is one of the most common reasons sidewalks fail prematurely here. We walk every site before quoting and assess root proximity honestly. If there is a risk, we present options rather than pour over the problem and leave you with a sidewalk that heaves again in three years.
We pull permits before work begins and schedule the town inspection at completion. Sidewalk work in San Anselmo requires it, and unpermitted concrete can become a problem when you sell. The inspection sign-off means an independent set of eyes confirmed the work meets local standards.
Town of San Anselmo Community DevelopmentThe clay-heavy soils throughout the Ross Valley move with every wet-dry cycle. We compact the gravel base to the depth the site conditions require, not to a generic standard. That is the step most at risk of being rushed on competitive bids, and it is the one that most directly determines how long the sidewalk holds.
We have worked on sidewalk projects from San Anselmo to Tiburon to Richmond. That range gives us direct experience with the soil types, drainage patterns, and permit processes that vary across the region - and we apply that local knowledge to every project in San Anselmo.
American Concrete Institute - concrete standardsSan Anselmo Concrete is a local contractor - not a large company dispatching crews from outside the county. We know the soil, the permit process, and the tree-root challenges that come with working in the Ross Valley. Before you hire anyone, verify their license on the California Contractors State License Board - including ours. A licensed, insured contractor is non-negotiable for any concrete work in San Anselmo.
