Napa Concrete is a licensed concrete contractor serving San Rafael, CA. We build concrete sidewalks, driveways, patios, retaining walls, and steps for homes throughout the city - from the postwar ranch homes of Terra Linda to the older hillside streets above Fourth Street. We handle every permit and reply within 1 business day.

San Rafael has some of the most varied sidewalk conditions in the North Bay. Older neighborhoods near Fourth Street and Mission Avenue have mature trees whose roots have been lifting concrete for decades. Terra Linda and Sun Valley ranch neighborhoods have 1950s and 1960s sidewalks that are due for replacement. We remove damaged sections, address root issues where possible, and pour to current ADA slope and finish standards. See our concrete sidewalk building service for full details.
The wide range of property types in San Rafael means driveway work here is rarely one-size-fits-all. A postwar ranch home in Terra Linda with a standard flat lot is a different project from a hillside home above downtown with a steep approach and limited street access. We scope each driveway project to the specific site conditions and give you a written estimate that reflects the real cost of your property, not a generic square-foot number.
San Rafael gets around 37 inches of rain per year - more than most Bay Area cities - and that concentrated wet season means patios here need to be built with drainage slopes that actually move water away from the house. A properly poured concrete patio handles San Rafael winters without heaving, settling, or creating pooling water near the foundation.
San Rafael's hillside neighborhoods - the streets above downtown, the areas near Dominican University, and the slopes off Mission Avenue - routinely have grade changes that require retaining walls to hold soil and prevent erosion. Concrete retaining walls are the most durable option for Marin County's wet winters, where timber and block alternatives tend to shift or deteriorate faster.
Many of San Rafael's older homes - including mid-century Craftsman and Spanish-style houses near downtown - have front steps that have cracked, settled, or heaved from clay soil movement and decades of wet winters. Replacing failing steps with properly formed concrete improves safety and fits the character of older San Rafael neighborhoods.
San Rafael is Marin County's oldest and largest city, incorporated in 1874, and a large share of its housing stock reflects that age. Many homes in the city were built before 1980, with significant numbers dating to the 1940s and 1950s. That means a lot of the concrete flatwork across San Rafael - driveways, walkways, patios, steps - is now 50 to 70 years old and has been through a very long cycle of wet winters and dry summers. The combination of age, clay soil movement, and root intrusion from large mature trees puts most of this older concrete well past its service life. On top of that, homes in San Rafael's hillside neighborhoods face steeper terrain and heavier drainage loads than most California cities, which adds complexity to any concrete project above the flatlands.
The clay soils common across Marin County swell when winter rain arrives and shrink as the dry season sets in. That slow seasonal movement is the reason you see raised and cracked sidewalk panels throughout San Rafael's older neighborhoods - it is not age alone, but age combined with soil movement underneath. San Rafael also receives significantly more annual rainfall than inland cities, which means water management has to be designed into every concrete project, not added as an afterthought. The City of San Rafael Community Development Department enforces permit and inspection requirements for most concrete work in the city.
We pull permits through the City of San Rafael Community Development Department and are familiar with the plan-check and inspection process for residential concrete work in this city. San Rafael is the seat of Marin County government, which means the building department handles a high volume of permits and has established review timelines we plan around. Properties range from the flat, accessible ranch homes of Terra Linda and Sun Valley to steep, tree-covered hillside lots above downtown where equipment access requires planning.
Fourth Street is San Rafael's main downtown corridor and a landmark most residents use as a reference point. The Marin County Civic Center - the Frank Lloyd Wright-designed building just north of downtown - is one of the most recognizable structures in the Bay Area and sits in a neighborhood of mostly postwar homes. The Canal area in the southeast has older multi-family housing closer to the water. We have worked on properties across all of these neighborhoods.
We also serve homeowners in nearby Napa and Novato and other Marin and Napa County communities. If your project is in San Rafael or nearby, call us and we will walk you through the process.
We respond within 1 business day. We will ask about the type of work, the approximate size of the area, and the property address. No measurements or drawings needed before you call - just a description of what you are trying to fix or build.
We walk the property, assess soil conditions, drainage, access, and any existing concrete we are removing. For hillside properties we specifically note terrain and access constraints. The written estimate breaks out each cost component so you know what you are paying for - no bundled totals.
We handle the City of San Rafael permit application for all work requiring one. The City of San Rafael typically processes residential permits in one to two weeks. We confirm your start date once the permit is approved and schedule around your availability.
Most residential concrete projects in San Rafael take two to five on-site working days. A city inspector verifies permitted work. Before we leave, we go over cure time requirements - new flatwork needs at least seven days before vehicle traffic and 28 days for full strength.
We serve all of San Rafael, CA - from Terra Linda to the hillside streets above Fourth Street. Free on-site estimates, written quotes, and full permit handling. We reply within 1 business day.
(707) 254-6177San Rafael is Marin County's largest city and its county seat, with a population of roughly 61,000. Incorporated in 1874, it is one of the oldest cities in the Bay Area, and that history shows in the variety of its housing stock. The Terra Linda neighborhood, developed in the 1950s and 1960s, is filled with single-story ranch homes on modest flat lots - the kind of property that is now reaching the age where driveways, walkways, and patios need attention. The neighborhoods on the hills above downtown have older, more architecturally varied homes - Craftsman bungalows, Spanish-style stucco houses, and mid-century custom builds - often on steep, wooded lots near Dominican University of California and along Mission Avenue. The Canal neighborhood in the southeast is denser and closer to the water, with a mix of older apartments and smaller single-family homes.
Downtown San Rafael centers on Fourth Street, a walkable main street with local shops and restaurants that most residents consider the heart of the city. The Marin County Civic Center - the Frank Lloyd Wright-designed building that opened in 1962 - sits just north of downtown and is a landmark that defines the area's identity. San Rafael sits at the intersection of US-101 and Sir Francis Drake Boulevard, making it the transit and commercial hub of central Marin County. Nearby communities we also serve include Novato to the north and Napa across the county line.
