"We had a foundation issue in one corner of the house - doors were sticking badly after last winter. The team came out quickly, explained exactly what was causing it, and had it repaired in two days. Six months later, everything is still solid."
Michael T., San Rafael - Foundation repair
"Our chimney mortar was in rough shape - crumbling in places and clearly letting moisture in. They matched the original mortar well and finished the tuckpointing in one day. No mess, no smell, and the chimney is ready for this season."
Karen S., Mill Valley - Tuckpointing
"We wanted a stone veneer on the front of our house and were not sure if it was even possible on our older stucco. They walked us through the options, pulled the permit, and finished in four days. The house looks completely different now."
David L., Corte Madera - Stone veneer installation

We aim to respond to all inquiries within 1 business day and can typically schedule same-week visits for non-emergency assessments.
Yes - the marine layer that settles over the Ross Valley most mornings carries moisture that works into mortar joints every single day, not just during storms. Chimneys and north-facing walls in Larkspur can show significant mortar deterioration in 15 to 20 years rather than the 30-plus years typical of drier climates.
Absolutely. Even moderate tremors - the kind that rattle dishes without making the news - can loosen mortar joints or crack a clay tile liner inside the flue. The Bay Area experiences minor seismic activity regularly, and the damage is often invisible from the ground until someone looks inside with proper equipment.
Homes built before 1950 typically used softer lime-based mortar. If you replace it with modern hard cement mortar, the mismatch means the bricks - not the joints - absorb stress and crack. The Brick Industry Association recommends always matching mortar hardness to existing materials.
If you notice doors or windows sticking for the first time, or cracks wider than a pencil line near doorframes, do not wait. Larkspur's expansive clay soils mean foundation problems almost always worsen with each wet-dry cycle. Early repairs cost a fraction of what a full stabilization job runs after a problem has had years to develop.
Often yes. Walls over a certain height on sloped lots typically require a permit and may need an engineer's stamp in Marin County. Drainage behind the wall is also critical - a retaining wall without proper drain aggregate will fail faster than one built on flat ground, especially after heavy winter rains.
It can. Properties near the historic Magnolia Avenue corridor may be subject to design review before exterior masonry work begins. The City of Larkspur's Community Development Department can confirm whether your address requires prior approval. A local contractor familiar with Marin will flag this before, not after, the work starts.

Since 2019 we have completed masonry projects across Marin County, working on homes ranging from 1920s-era bungalows with original brick foundations to newer hillside construction with stone veneer and custom outdoor living spaces. Our team offers 16 services, and every job starts with a free on-site estimate and a written scope of work.
Learn more about our team and approachLate spring through early fall is ideal for most outdoor masonry in Marin County. Fresh mortar needs mild, dry conditions to cure properly. If you notice active water intrusion heading into winter, address it promptly rather than waiting for better weather.
Hairline cracks under a quarter-inch wide are usually cosmetic. Cracks wider than a pencil line, cracks that run diagonally from corners, or cracks that have grown since you first noticed them warrant a professional look. When in doubt, a free estimate costs nothing.
Small cracks in mortar let water in. Wet winters in Larkspur push that moisture deeper with every storm. What costs a few hundred dollars to fix now can become a multi-thousand-dollar rebuild if left for two or three wet seasons.
Not sure what you are looking at or how urgent it is? Give us a call at (415) 390-3464 - a five-minute conversation usually gives you a clear direction.
Larkspur is a small, established city in California with a population of about 12,000 and a housing stock that dates back well over a century. Many homes here were built between the 1920s and 1960s, which means original brick chimneys, older concrete foundations, and masonry that has been absorbing Marin County winters for decades. You can read more about Larkspur's history and neighborhoods on Wikipedia.
The city sits at the base of and on the slopes of Mount Tamalpais, with many residential streets winding up into wooded hillside neighborhoods filled with redwood and bay laurel trees. Neighborhoods like Baltimore Canyon have steep lots where retaining walls, drainage, and foundation conditions all require extra care. The historic downtown along Magnolia Avenue anchors the city center, and the Larkspur Ferry Terminal connects residents to San Francisco - meaning many households have limited time and want a contractor they can trust to manage a project without constant oversight.
The marine fog that rolls through Larkspur year-round is hard on masonry. Combined with heavy seasonal rainfall - around 40 inches a year - and the expansive clay soils that shift with each wet-dry cycle, Marin County homes face real structural stress that shows up in cracked foundations, deteriorating chimney mortar, and shifting retaining walls. Larkspur Masonry has been working on these kinds of problems in Larkspur and the surrounding communities since 2019, and we understand what local homes actually need.
