Crumbling mortar, missing caps, failed flashing - each one lets water in. Marin winters are hard on chimneys, and small problems caught now cost far less than water damage discovered in January.
Chimney repair in San Anselmo addresses the full masonry system - mortar joints, the flue liner, the cap, the crown, and the flashing where the chimney meets the roof - and most jobs are completed in a single day, with homes remaining livable throughout.
A chimney does more than carry smoke out of your house. It protects your home from heat, fire, and carbon monoxide. When any part of that system breaks down, your home is at risk even if the fireplace still appears to work fine. San Anselmo's roughly 40 inches of annual rain fall mostly between November and March, which is hard on mortar joints and flashing. Most of the town's homes were built before 1970, and chimneys of that era are overdue for a professional look.
Chimney issues and masonry deterioration often go together. If your chimney needs mortar work, it is worth asking about tuckpointing, which is the proper method for restoring mortar joints throughout a brick structure - not just a surface patch. And if you are thinking about fireplace installation, we handle that too.
Chalky white streaks or patches on the brick exterior mean water is moving through the masonry and carrying mineral deposits to the surface. In San Anselmo's wet winters, this kind of moisture intrusion tends to get worse each season if it is not addressed. It is one of the earliest visible warnings that your chimney needs attention.
Stand back and look at your chimney from the yard. If the mortar lines between bricks look sunken, cracked, or are falling out in places, that repair should not wait. Mortar is what holds the structure together, and once it starts to go, water gets in faster during the heavy rains Marin County sees each winter.
Brown or yellowish ceiling stains around the fireplace mean water is getting in somewhere - often through failed flashing or a cracked chimney crown. This kind of damage typically shows up after the first big rainstorms of the season, which in San Anselmo arrive in November or December.
After any notable seismic event in the Bay Area, have your chimney inspected even if it appears fine. Earthquakes can loosen mortar and crack the liner inside the flue without leaving obvious external signs. Using a fireplace with hidden earthquake damage is a real fire risk.
Every chimney job starts with a real inspection - from the ground, from the roof if needed, and from inside the firebox. For a thorough evaluation, we use a small camera to look inside the flue, which is the only reliable way to check for liner damage after seismic events. What we find determines what we recommend. If mortar joints are deteriorated but the structure is sound, targeted tuckpointing is usually the right fix. If the flue liner is cracked or the system is too far gone to repair efficiently, we will tell you that honestly and walk you through the options for fireplace and chimney installation.
We handle the full scope of common chimney repairs: mortar repointing, chimney cap replacement, crown repair and rebuilding, flashing repair or replacement, flue liner repair, and structural brick replacement. Permit applications with the Town of San Anselmo's Community Development Department are included for any job that requires them - we manage that process so you do not have to.
For chimneys where the joints between bricks have worn down, cracked, or are crumbling away and allowing water to enter the masonry.
Suited for chimneys with a missing, rusted, or cracked cap that is allowing rain, debris, and animals to enter the flue directly.
For homes where water is entering through the metal seal where the chimney meets the roof, causing staining on ceilings or walls near the fireplace.
When the concrete cap at the top of the chimney is cracked or crumbling, allowing water to penetrate the entire chimney structure from the top down.
Recommended after a notable seismic event or for older chimneys where the interior liner shows cracks that could allow heat or sparks to reach combustible framing.
A starting point for homeowners who want an honest evaluation before fire season, or who have not had the chimney professionally checked since buying the home.
San Anselmo's combination of wet winters, an older housing stock, and seismic activity creates chimney repair demands that differ from most of California. The town is known for its mature oak, bay laurel, and redwood trees - which are beautiful but drop leaves and debris that collect on chimney caps and hold moisture against the masonry. Homeowners with heavy tree cover should check their cap more frequently, and make sure the screen is intact to keep debris and animals out of the flue. A cracked crown or missing cap that might cause minor staining in a drier climate can allow real structural water damage here between November and March.
We serve homeowners throughout this part of Marin County - from San Anselmo's hillside neighborhoods to Mill Valley and Fairfax. The National Fire Protection Association recommends annual chimney inspections regardless of use frequency - a guideline that is especially relevant in the Bay Area, where seismic events can cause hidden liner damage between scheduled check-ups.
We respond within 1 business day. You do not need to know exactly what is wrong - just describe what you have noticed. We ask a few questions and schedule a time to come look in person.
We examine the chimney from the ground, the roof, and inside the firebox. For a complete evaluation, we use a camera to inspect the flue liner. This step is what makes an honest repair quote possible and typically takes 30 to 60 minutes.
After the inspection, we walk you through exactly what we found in plain terms. A written estimate follows, breaking down each item proposed and what it will cost. If a permit is required, we handle the application with the town.
Most repairs are completed in a single day. We protect your floors and clean up before leaving. If mortar work was done, we give you the curing time before the fireplace can be used. Before we leave, we walk you through what was repaired.

(415) 723-8059No honest contractor can give you a fair price without seeing what they are actually dealing with. We inspect the flue liner with a camera before recommending anything. That inspection is included - not an upsell - because it is the only way to catch liner damage from seismic events or years of use that is invisible from the outside.
Many San Anselmo homes are 60, 80, or over 100 years old. Some contractors use that as a reason to recommend a full rebuild when targeted repairs are all that is needed. We assess what is actually failing, repair what needs to be repaired, and tell you honestly what can wait - so you pay for the work your chimney actually needs.
Every chimney repair we do is backed by a California masonry contractor license and full general liability insurance. You can verify our credentials on the California Contractors State License Board website. That matters for your safety and for the documented record of work that buyers and their inspectors will ask about if you sell.
Fall is the busiest season for chimney work in Marin - everyone wants repairs done before the rains. We know this and we schedule accordingly.

We work on homes throughout San Anselmo and surrounding Marin County - from older craftsman bungalows near The Hub to hillside properties above Sir Francis Drake Boulevard. If you want to discuss your specific situation before booking anything, just call.
Tuckpointing removes deteriorated mortar and replaces it with fresh material - the right long-term fix for chimneys and brick walls where mortar has worn down over decades.
