Serving Larkspur, CA and surrounding areas. (415) 390-3464
Larkspur Masonry is a licensed masonry contractor serving San Anselmo, CA with brick repair, foundation repair, and chimney and drainage work. We have worked on San Anselmo properties since 2019 and understand the pre-war Craftsman homes, hillside lots, and flood-zone drainage challenges that define masonry work here. We reply to every inquiry within one business day.
A large share of San Anselmo's homes were built before World War II, and the brick on those properties has had 80 or more years of wet winters, tree root pressure, and freeze-thaw cycles working on it. Spalled brick faces, crumbling mortar joints, and sections of wall that have started to bow need attention before moisture gets behind the face and causes structural damage. Our brick repair work on older San Anselmo homes uses lime-compatible materials that match the original construction and do not crack the surrounding brick.
Homes built in San Anselmo in the 1920s and 1930s often have unreinforced concrete or rubble-stone foundations that were not designed to today's seismic or drainage standards. Hillside lots that slope toward the house concentrate water at the foundation during heavy rain, and homes near San Anselmo Creek have periodic flood exposure that saturates foundation walls from the outside. Cracks and moisture intrusion in these older foundations are best addressed early, before the damage reaches the framing above.
Craftsman bungalows and older homes throughout San Anselmo typically have original brick chimneys built with lime mortar that has softened over the decades. San Anselmo's valley location traps fog and moisture, which keeps chimney brick damp and accelerates joint deterioration faster than in drier areas of Marin. Repointing the mortar joints and capping the crown are the two most effective repairs for stopping water intrusion on older San Anselmo chimneys.
Tuckpointing removes softened or damaged mortar from between brick or stone courses and replaces it with fresh, properly matched mortar before water gets in and does serious damage. On pre-war San Anselmo homes, this work requires matching the original joint profile and selecting a mortar that is softer than the surrounding brick - harder modern mortars push stress into the brick face rather than the joint. This distinction matters on historic masonry in San Anselmo, where the brick itself is not replaceable with modern stock.
Many hillside properties in San Anselmo have terraced yards held by retaining walls that were built decades ago without modern drainage behind them. When saturated soil pushes against those walls in winter, cracks and leaning are common. Replacing or reinforcing a retaining wall on a sloped San Anselmo lot requires drainage planning specific to the hillside - weep holes and a gravel drainage layer behind the wall are not optional in this climate.
Walkways on San Anselmo properties get lifted and cracked by the mature oaks and redwoods that root beneath them - a common problem throughout the wooded residential streets. Replacing a cracked walkway without addressing the root system beneath it results in the same damage within a few years. New walkways on these lots need root barriers or tree-friendly paving options, along with a compacted base layer that accounts for the organic soil movement common under older trees.
San Anselmo is a small Marin County town with a housing stock that skews old. Most of the residential neighborhoods were developed in the early 1900s through the 1940s, which means a large share of the homes here have foundations, chimneys, brick planters, and walkways that are 70 to 100 years old. The masonry on those properties was built with lime-based mortars and softer brick that behave very differently from modern materials. Using today's standard Portland cement mix on a 1920s Craftsman chimney is a common mistake - and it accelerates the cracking of the original brick rather than stopping it. A contractor who regularly works on historic masonry in Marin County towns knows how to select the right mortar and match the original joint profile.
The town's location in a valley also creates specific drainage conditions. San Anselmo Creek runs through the center of town, and the Marin County Flood Control District manages the creek flood zone that affects properties near the downtown core. Homes in that zone have had foundation and drainage masonry exposed to periodic flooding - a condition that requires inspection and, often, sealing or rebuilding of below-grade masonry to prevent water intrusion from returning. The hillside streets that climb away from the valley floor face the opposite problem: winter runoff concentrates at the base of slopes and against any foundation or retaining wall in its path.
Our crew works throughout San Anselmo regularly, and we understand the local conditions that affect masonry work here. Building permits for structural masonry go through the Town of San Anselmo Building Division, and we are familiar with the permit process and review timeline for residential projects in town.
The homes we see most often here are the Craftsman bungalows and older wood-frame houses near The Hub - San Anselmo's downtown shopping and dining area along Sir Francis Drake Boulevard - along with the hillside properties that climb above the valley on both sides. The older in-town homes tend to have original brick chimneys and stone or concrete foundations that need lime-compatible repair work. The hillside properties deal with slope drainage, retaining wall stress, and sometimes limited truck access on narrow roads above town.
We also work regularly in the neighboring communities. Fairfax is directly adjacent to San Anselmo and has a very similar housing profile - older homes, wooded lots, and hillside drainage challenges that call for the same masonry approach. To the east, San Rafael is a short drive along Sir Francis Drake Boulevard and a regular part of our service area.

(415) 390-3464San Anselmo is a small Marin County town of about 12,000 residents, known for its walkable downtown, mature tree canopy, and neighborhood character that feels more like a village than a suburb. The town sits in a valley between wooded hills, with Sir Francis Drake Boulevard running through the center and connecting it to San Rafael to the east and Fairfax to the west. The commercial heart of town - known locally as The Hub - is a stretch of shops, restaurants, and antique stores that most residents visit regularly. Residential neighborhoods spread out from The Hub in both directions along the valley floor and climb up the hillsides on both sides of town. For a fuller overview of the town's history and geography, the San Anselmo Wikipedia article is a reliable starting point.
The housing stock in San Anselmo leans older and almost entirely single-family. Pre-war Craftsman bungalows are common throughout the streets nearest the downtown core, and many homes on the hillside streets above town date to the same era. The majority of residents are long-term homeowners who have invested in their properties over the years. San Anselmo Creek, which runs through the middle of town, has flooded significantly more than once - and those events have shaped how homeowners here think about drainage, foundation condition, and water management. Adjacent Fairfax shares similar housing ages and drainage challenges, and we serve both towns as part of our regular Marin County work.
