Crumbling mortar between your bricks is how water finds its way in. We remove the old material, pack in fresh mortar matched to your home, and seal the wall before the next storm hits.
Brick pointing in San Anselmo is the process of removing old, deteriorated mortar from between the bricks and replacing it with fresh material - most chimney and small wall jobs take one to two days, with larger projects running three to five days depending on how much material needs to come out.
Mortar is softer than brick by design - it absorbs stress and moisture so the bricks themselves do not crack. When that mortar fails, water gets in, freezes on cool nights, and starts breaking the bricks apart from the inside. Catching deteriorating joints early is almost always far cheaper than replacing damaged bricks or rebuilding a section of wall. San Anselmo homes built before 1950 are especially important to watch because the original lime-based mortar in those walls has typically reached the end of its useful life. If your brick masonry also has broader structural issues, our foundation repair service can address those at the same time.
The mortar mix matters as much as the labor. Using too-hard modern mortar on an older San Anselmo home traps moisture inside the bricks and causes spalling - the brick face starts flaking off in layers. A mason who understands older construction will assess what is already there and match the new material to what the bricks were built to work with.
Walk up close to your chimney, garden wall, or any brick surface and look at the lines between the bricks. If the mortar looks sandy, crumbly, or has gaps where it has pulled away from the brick edges, that material has failed. A simple test: press a key gently into a joint - if material comes out easily, the mortar has lost its strength.
Chalky white streaks or patches on brick after San Anselmo's rainy season are a sign water is moving through the wall and carrying dissolved salts to the surface. This staining - called efflorescence - tells you moisture is getting into the joints and working its way through the brick. It is one of the earliest visible warnings that mortar is no longer doing its job.
If you see water stains on the ceiling near your fireplace after a rainstorm, or dampness on an interior wall that backs up to an exterior brick surface, failing mortar joints are a likely cause. San Anselmo's concentrated winter rainfall means even small gaps in chimney or wall mortar can let in significant water during a heavy storm.
Many San Anselmo homes from the early and mid-twentieth century still have their original mortar, designed to last 50 to 75 years under ideal conditions. Given the town's wet winters and seismic activity, original mortar on a pre-1960 home has likely reached or passed the end of its useful life - even if it does not look obviously damaged yet.
We perform brick pointing and mortar repointing on chimneys, exterior walls, garden walls, and decorative brick features throughout San Anselmo and the surrounding Marin County towns. Every job starts with a free on-site visit where we look closely at the condition of your mortar, the type of brick you have, and how accessible the work area is. You get a written price before any work begins - if we find something unexpected once we are into the job, we stop and talk to you before anything changes. For homeowners whose brickwork has broader maintenance needs, we also handle tuckpointing work on older masonry where the joints need both structural repair and a cleaner finished appearance.
The mortar selection is the most important decision on any repointing job. We assess your existing mortar and your brick type before choosing a mix - older homes need a softer, more flexible material than what you would find at a hardware store. Forcing a hard modern mortar into a pre-war San Anselmo home causes brick damage that costs far more to fix than the original pointing. The National Park Service Preservation Briefs on repointing historic masonry are the industry standard reference for this work, and they guide our mortar selection on every older home.
For homeowners dealing with water stains near the fireplace or a chimney that has not been touched since the home was built - the most common brick pointing job on older San Anselmo properties.
For homeowners with brick exterior walls showing efflorescence, crumbling joints, or visible gaps - addressed before Marin's rainy season drives water deeper into the structure.
For homeowners with original brick garden walls, entry pillars, or decorative features whose mortar has deteriorated - repaired to blend with the existing character of the masonry.
For pre-1950 San Anselmo homes where the original lime-based mortar must be matched to avoid brick damage - the right mix selected after assessing what is already there, not just defaulting to modern materials.
San Anselmo gets most of its rain between November and April, and some years bring intense storms that dump several inches in a short period. That concentrated moisture is hard on mortar joints - water soaks in during the rainy season, and the long dry summer causes the mortar to shrink and crack over time. The seismic activity common throughout the Bay Area adds another layer: even minor ground movement puts stress on masonry joints in ways that are not always visible from the ground. Homeowners in Fairfax deal with the same climate and seismic exposure, and we bring that Marin-specific understanding to every pointing job in the area.
The housing stock here matters just as much as the climate. A large share of San Anselmo homes were built between the 1900s and 1950s, and those properties often still have original mortar that was never meant to survive a century of Marin winters. Using modern hard-set mortar on those walls is one of the most common mistakes a non-local mason makes - it looks fine for a year or two and then causes the brick face to flake off. Parts of Ross share the same early-twentieth-century construction profile, and matching mortar to the original material on older homes is standard practice for us across the entire Ross Valley.
Reach out by phone or through our contact form and describe what you are seeing - crumbling joints, water stains, or a wall that has not been touched in years. We respond within 1 business day to schedule a free on-site visit.
We look closely at the mortar joints, check the condition of the bricks, and assess access - whether we need a ladder or scaffolding to reach a chimney or upper wall. You receive a written estimate explaining scope, timeline, and cost before you decide anything.
Once you approve the estimate, we set a start date. Your only task is clearing the work area - move patio furniture, potted plants, or vehicles away from the wall. You do not need to be home during the job, but it helps to have a number we can reach if a question comes up.
The crew grinds out old mortar, cleans the joints, and packs in fresh material tooled to match the original profile. At completion we walk you through the finished work and explain the curing period - fresh mortar needs 24 to 48 hours before it gets wet and about a month to reach full strength.

(415) 723-8059We assess your existing mortar and brick type before selecting a mix - not after. Older San Anselmo homes need a softer, lime-rich mortar that allows moisture to escape through the joints rather than trapping it in the brick. Using the wrong mortar is the single most common cause of repointing work that fails early.
Quality repointing requires removing old mortar to at least three-quarters of an inch before packing in new material. Skimming new mortar over old, failing joints is a shortcut that looks fine for a season and then fails. Every joint we work on is properly raked out before new material goes in. The Brick Industry Association sets the standard, and we follow it on every job.
San Anselmo sits in a seismically active part of Marin County, and minor ground movement loosens mortar joints in ways that are not always visible from the ground - especially in tall, freestanding chimney stacks. If your home has experienced noticeable shaking, we inspect chimney and freestanding wall joints even when the surface looks intact.
You get a clear, itemized price before any work begins. If we find something unexpected - a brick that needs replacing before the new mortar will hold - we stop and show you before doing anything that changes the cost. You stay in control of your budget from start to finish.
We have repointed chimneys, garden walls, and exterior facades on homes throughout San Anselmo and the surrounding Marin towns - from the pre-war Craftsman neighborhoods near The Hub to the hillside properties above Sir Francis Drake Boulevard. That local track record means we know what the work looks like on homes like yours, and we know what holds up here.
