San Rafael Asphalt Paving serves Larkspur homeowners and commercial property owners with asphalt resurfacing, driveway replacement, crack sealing, and drainage work. We have worked throughout this city since 2018 and know how the combination of clay soils, mature tree roots, and wet winters affects paved surfaces here differently than in other parts of Marin County.

Larkspur has a high share of homes built between the 1920s and 1970s, and many original driveways are now failing from decades of wet winters and root pressure from below. When the base is still sound but the surface has cracked and oxidized beyond patching, our asphalt resurfacing service removes the deteriorated top layer and installs a fresh hot-mix surface without the cost of full base replacement.
Hillside lots in Larkspur have driveways that often follow the slope and are long enough that proper grading for drainage is essential - water running back toward the garage is a common problem on older installations. We design and pave replacement driveways on both the flat streets near downtown and the steeper hillside addresses west of Magnolia Avenue, matching the base depth and drainage solution to what each lot actually requires.
Larkspur gets most of its rain between November and March, and any open crack in an asphalt surface lets water into the base, where it weakens the foundation from below. Sealing cracks in fall - before the first storms arrive - is the lowest-cost way to extend the life of an otherwise functional driveway and avoid a full replacement in the near term.
Near Corte Madera Creek and the low-lying eastern parts of Larkspur, softer soils can settle unevenly under paved surfaces, which eventually punches through as a pothole. We assess whether settlement is active before selecting a repair method - filling a pothole in a settling area with cold patch is a temporary fix that fails quickly, so we match the repair type to what the ground is actually doing.
Marine fog from San Francisco Bay keeps asphalt surfaces in Larkspur damp even during the dry season, which accelerates oxidation and makes surfaces brittle faster than in drier climates. Sealcoating every two to three years restores a protective layer over oxidized asphalt and closes micro-cracks before they open wide enough to let water through.
Properties near Corte Madera Creek sit in areas where the ground stays saturated long after storms pass, and paved surfaces on these lots can hold water that has nowhere to go. We install surface drains, channel drains, and grading corrections that direct runoff away from foundations and off paved areas before the standing water undermines the base.
Larkspur is a small, largely built-out city where most homes were constructed between the 1920s and 1970s. That means many driveways, parking areas, and private paved surfaces are now 40 to 80 years old and approaching or past the end of their useful life. On the hillside lots west of the downtown area, those older surfaces sit on clay soils that have been expanding in winter and contracting in summer for decades, working the pavement from below every single year. Add mature redwoods, oaks, and ornamental trees whose roots actively grow under paved surfaces, and you have a combination that makes routine patching increasingly ineffective - the underlying forces just keep pushing through. A contractor who treats these driveways as simple flat-lot resurfacing jobs will miss the drainage grading and root barriers that actually determine whether the new surface holds up.
The eastern edge of Larkspur, near Corte Madera Creek and the bay flats, presents a different problem. Low-lying properties in this area sit on soils that stay wet for extended periods after heavy rain, and the creek itself can overtop during major storm events. Paved surfaces on these lots that drain poorly will saturate the base material, causing premature failures that look like ordinary cracking but are actually base collapse from below. The FEMA flood zone maps show parts of east Larkspur in or adjacent to mapped flood zones, which affects how drainage work needs to be designed for those specific addresses.
Our crew works throughout Larkspur regularly, and we pull permits through the City of Larkspur for any right-of-way or grading work as a standard part of our process here. Larkspur has its own permit desk separate from Marin County, and knowing which jobs require city review - versus what can proceed without a permit - saves our customers time and avoids stop-work situations. From our base in San Rafael, we can reach most Larkspur addresses in under 15 minutes, which matters when a homeowner needs a fast response before the rainy season arrives.
On the ground, Larkspur means knowing the difference between a flat address near Magnolia Avenue and a hillside address above the historic downtown where streets narrow and trees hang over the roadway. The Baltimore Canyon neighborhood sits closest to the redwood-filled open space preserve in the hills above town, and driveways there face the heaviest root pressure and moisture from the surrounding canopy. We also regularly serve the neighboring communities of San Rafael and Corte Madera, which border Larkspur and share the same clay-soil and coastal-moisture challenges.
We respond within one business day. Share your address and a brief description - resurfacing, new driveway, crack repair, drainage work - so we can review the location and any permit requirements before we visit. Larkspur hillside addresses sometimes need extra planning for equipment access.
A member of our crew visits your property, checks the surface condition, evaluates the base, looks at root pressure and drainage, and measures the area. You receive a written estimate before we ask for any commitment. We also confirm at this stage whether a city permit is needed for your specific project.
We schedule your project during the dry season whenever possible, and we pull any required permits from the City of Larkspur in advance. For hillside driveways, we plan equipment staging to minimize impact on the street and neighboring properties.
When the work is done, we walk the surface with you, confirm drainage is running the right direction, and give you a curing timeline - typically 24 to 72 hours before vehicle traffic depending on weather. We leave the site clean and clear.
We serve all of Larkspur - from the flat streets near Magnolia Avenue to the hillside neighborhoods above the city. Get a written estimate with no commitment required.
(628) 277-0007Larkspur is a small city in southern Marin County, tucked between the hills of the Marin headlands to the west and the tidal flats of Corte Madera Creek to the south and east. The city is largely built out, with most of its residential neighborhoods dating to the early and mid-20th century. Historic Magnolia Avenue runs through the heart of downtown, lined with older storefronts, restaurants, and street trees that have defined the city character for generations. The waterfront Larkspur Landing area on the eastern edge of town, near the Larkspur Ferry Terminal, provides a direct ferry connection to San Francisco and anchors a shopping and mixed-use district at the bay edge.
Residential properties here range from Craftsman bungalows and ranch-style homes on flat lots near the downtown core to larger hillside homes climbing west toward the Baltimore Canyon Open Space Preserve. The hillside neighborhoods sit amid dense redwood canopy and mature oak trees - a setting that is beautiful but hard on paved surfaces. The combination of clay hillside soils and persistent root systems makes driveway and flatwork maintenance a routine part of owning a home in these neighborhoods. Neighboring Corte Madera to the north and Mill Valley to the south share many of the same property characteristics, and we serve homeowners across all three communities.
