San Anselmo Concrete serves homeowners in Larkspur with concrete sidewalk replacement, driveway building, retaining walls, and patio construction. We are licensed, locally operated, and respond to new requests within one business day.

Lifted and cracked sidewalk panels are a regular problem along Larkspur streets where mature trees line the public right-of-way. When the city notifies you that a panel adjacent to your property is your responsibility, you need the work done correctly the first time. Our concrete sidewalk building service includes root assessment and barrier installation to reduce repeat damage.
Canyon lots in Madrone Canyon and Baltimore Canyon sit on sloped terrain where soil movement is a constant concern. A properly built concrete retaining wall controls where soil goes when it gets wet, keeps your yard from creeping toward the driveway, and protects the foundation from lateral pressure after heavy rain.
Driveways on Larkspur hillside lots require careful attention to grade and drainage. Water that runs off a driveway toward the house or garage can cause long-term moisture problems, so slope and channel placement are built into every job we do here. We also address tree root intrusion before pouring to avoid the same cracking that damaged the original slab.
Many Larkspur homes sit above street level with a significant grade change between the sidewalk and the front door. Old wooden or brick entry steps that have settled, cracked, or become unsafe are a common replacement project here. Poured concrete steps with a proper footing outlast wood and pavers significantly in wet-winter conditions.
Larkspur summers are warm and mostly fog-free, which makes outdoor living space well worth investing in. A concrete patio handles the load from outdoor furniture, fire pits, and regular foot traffic without shifting or sinking the way decomposed granite or loose-set pavers do over time on hillside lots.
Larkspur sits at the foot of the Marin hills, and the geography divides the city into two distinct building environments. The flatter streets near Magnolia Avenue and the downtown corridor have more conventional flatwork challenges - root intrusion, aging concrete, sidewalk compliance notices from the city. The canyon neighborhoods above town are a different job site entirely: steep grades, narrow driveways, concentrated runoff, and soil that moves every wet season.
The city's housing stock is a mix of Victorian-era homes in the old town core and mid-century construction in the canyon subdivisions, many built between the 1940s and 1960s. Concrete poured at that time is now well past its useful life in many cases. When you replace it, the subgrade condition often turns out to be worse than the surface suggests - base material has washed out, roots have run under the slab, and grade has shifted. Accounting for all of that before the pour is the difference between a slab that lasts and one that fails again in a few years.
Winter rainfall in the Larkspur area is significant, and clay soil responds to it by expanding and then cracking as it dries in summer. Concrete work that does not account for this annual cycle - through proper control joints, base aggregate depth, and drainage design - will show the effects within a few seasons. Properties near Larkspur Creek may also fall within a mapped flood zone, which affects permit requirements and drainage design for any flatwork near the creek corridor.
We pull permits through the Larkspur Building Division for projects that require them, and we are familiar with the city's requirements for retaining walls, driveway alterations, and any work in the creek setback area. Permit timelines in Larkspur are generally reasonable, and we keep you updated on where your project stands in the queue.
Magnolia Avenue runs through the heart of old Larkspur and is one of the main streets we work off for access. The canyon roads - particularly in Madrone Canyon and Baltimore Canyon - are narrow and have limited turnaround space, so concrete truck routing and staging need to be planned in advance. We site- visit every canyon job before scheduling to confirm access before pour day.
We also work regularly in Corte Madera, Larkspur's neighbor to the south, where the terrain shifts to flatter bayfront lots and the work typically involves driveways and patios rather than the retaining and hillside work common in Larkspur. If your property spans the two cities or you have jobs at both, we handle them together.
Reach us by phone or through the contact form and describe the project. We reply to all new inquiries within one business day and will ask a few questions about your site before scheduling a visit.
We come to the property, walk the area, and assess base condition, grade, drainage, and root or access issues. You get a written estimate before any work is scheduled, with no cost or obligation for the visit.
If a permit is required, we submit it through the Larkspur Building Division and track it for you. We schedule around weather and your availability, with at least a week's notice before the crew arrives.
The crew handles demo, base prep, forming, pouring, and finishing. We walk the finished work with you before leaving and explain the cure timeline so you know when the surface is safe for traffic.
We serve Larkspur, CA for driveways, sidewalks, retaining walls, patios, and foundations. No obligation, no pressure - just an accurate written estimate.
(415) 604-1678Larkspur is a small city of about 12,000 residents in southern Marin County, incorporated in 1908. It is perhaps best known for the Golden Gate Ferry terminal at the southern end of town, which carries commuters to San Francisco across the bay. Magnolia Avenue forms the main commercial spine of old Larkspur, lined with restaurants and local shops in buildings that date to the Victorian era.
The residential neighborhoods spread from the flat streets near Magnolia into the canyon areas to the north and east. Madrone Canyon and Baltimore Canyon are the most distinct of these - narrow canyon roads, creekside lots, and homes that feel a world away from the commuter corridors below. Most of the housing in these areas was built between the 1940s and 1960s, with a significant stock of Victorian-era homes closer to downtown. Property lots vary considerably in size and slope depending on which part of the city you are in.
To the south, Larkspur borders Corte Madera, where the land flattens toward the bay and the housing stock shifts to post-war tract development. To the north, Larkspur shares the Ross Valley with San Rafael, Marin County's largest city and the county seat.
