Chimney sweep logs do not sweep chimneys. They loosen some creosote - which then falls where a brush and vacuum still have to collect it.
Chimney Company in San Marino, CA
Chimney repair in San Marino is rarely a simple patch job. The homes here, built largely between the 1910s and 1940s, carry original masonry fireplaces with clay-tile flues that have been absorbing decades of heat, moisture, and the occasional earthquake. When a crown cracks or a flue tile separates, the fix has to respect the original construction, not bury it under modern materials that don’t belong. Mantel Chimney Sweep has served San Marino since 2018, and we approach every repair as a restoration: diagnose the actual failure, show you the evidence, then use materials like DuraFlex and HeatShield that are built for the long term. Call (844) 821-5749 for a repair assessment.
Why San Marino Homes Are Different
San Marino’s housing stock is dominated by large Tudor, Spanish Colonial, and Mediterranean estates from the 1910s through the 1940s. Many of these homes still have their original multiple masonry fireplaces, often with clay-tile flues running through substantial two-story structures. Tall chimneys require careful ladder access, staging on steep slate roofs, and interior protection that keeps soot off Persian rugs and original hardwood. The ZIP codes we serve here, 91108 and 91118, include some of the oldest and most architecturally significant chimney systems in the San Gabriel Valley.
Climate shapes the work, too. Warm, dry summers and mild winters mean fireplaces get used sparingly, mostly for ambiance on cool evenings. Creosote buildup tends to be light, but that doesn’t mean flues are clean. Wildfire season and Santa Ana winds pull ash and debris down open flues, and we regularly find nests, leaves, and broken terra-cotta fragments lodged above the smoke shelf. The real issue in San Marino is rarely creosote volume. It’s age, deterioration, and the consequences of decades of deferred maintenance on chimneys that were built before modern liner standards existed.
There’s also the historic-preservation reality. San Marino enforces a careful, preservation-minded review of exterior and structural changes. That means technicians need to understand original chimney construction and know when a liner can be restored in place versus when a full replacement is the only responsible call. We work with that context every week.
Styles & brands we work with
Our Main San Marino Services
Most San Marino homeowners reach out to us for one of two reasons: they haven’t had their fireplace swept in years and want it done properly, or their dryer vent is clogged and they’ve heard the fire statistics. Both are core services for us.
Chimney Sweep in San Marino
A sweep in San Marino means working around original fireboxes, ornate mantels, and tall flues that haven’t been touched in decades. Our technicians use drop cloths, HEPA-filtered vacuums, and careful brush work that removes soot and light creosote without scouring original firebrick. We also inspect the flue as we go, because in homes from the 1920s, a clean surface often reveals cracks that were hidden under buildup. If you need a full cleaning on an older estate fireplace, Chimney Sweep in San Marino covers what to expect, how long it takes, and how to prepare.
Dryer Vent Cleaning in San Marino
Dryer vents don’t care how old your house is. A clogged vent in a 1935 Mediterranean estate is just as dangerous as one in a newer build, and many San Marino laundry rooms route vents through long interior wall cavities or out through tile roofs, which makes access harder than a straight exterior wall. We clean the full duct run, remove lint accumulation at the termination point, and verify that airflow is moving freely before we pack up. Dryer Vent Cleaning in San Marino explains the process and the specific risks of neglected vents in older homes.

Chimney Repair in San Marino
Chimney repair in San Marino usually starts with a visual clue: water staining on the ceiling near the fireplace, a chunk of terra-cotta on the roof, or a damp smell after rain. The homes here were built with clay-tile flues and lime-based mortar, both of which deteriorate over time. When a flue tile cracks or the mortar joints erode, heat and gases can reach combustible framing. That’s the failure point, and it’s why repair work here is a structural matter, not a cosmetic one. Mantel Chimney Sweep handles full-scope chimney repair in San Marino, from crown restoration to complete liner replacement, using materials from the professional chimney supply chain. Our Chimney Repair service covers the full range of what a deteriorating chimney needs before it becomes a fire or carbon monoxide risk.
Chimney Cap Replacement
Signs you need it
You have a missing, rusted, or storm-damaged cap, or you’ve found debris, nests, or water inside the flue.
What it costs in San Marino
A standard chimney cap replacement in San Marino typically runs between $300 and $900 depending on flue size, roof access, and whether a custom bracket is required.
How we do it
We measure the flue opening, remove the old cap and any damaged mounting hardware, install a stainless or copper cap sized to the flue, and seal the mounting points against water intrusion.
Chimney Crown Repair
Signs you need it
You see cracks in the concrete crown, spalling along the edges, or water staining on the chimney breast below the roofline.
What it costs in San Marino
Crown repair in San Marino typically ranges from $450 to $1,200, with full custom crown replacement on oversized estate chimneys running $1,000 to $2,500.
How we do it
We clean the existing crown, repair or remove damaged concrete, apply a proper expansion joint between the flue tile and crown, and seal the finished surface with a waterproofing compound rated for chimney exposure.
Chimney Liner Installation
Signs you need it
An inspection reveals cracked flue tiles, gaps between tile sections, or spalled clay pieces at the cleanout, meaning combustion gases are no longer fully contained.
What it costs in San Marino
Chimney liner installation in San Marino starts around $2,500 and can exceed $5,000 depending on flue length, access, and whether a full flexible stainless system like DuraFlex is required.
How we do it
We remove or bypass the damaged clay tiles, install a properly sized flexible stainless liner from a brand like DuraFlex, insulate it where required by code, and connect it to the appliance or fireplace with a sealed top plate and cap.
Chimney Flashing Repair
Signs you need it
You see water stains on the ceiling around the chimney chase, rust trails on the roof flashing, or lifted flashing edges after a storm.
What it costs in San Marino
Chimney flashing repair in San Marino typically ranges from $450 to $1,400, with full replacement on large custom chimneys running higher.
How we do it
We remove the damaged flashing, install new step and counter flashing sized to the chimney and roof pitch, and seal all transitions with a high-temperature, weather-rated sealant.
What Chimney Repair Costs in San Marino
| Item | Typical range in San Marino |
|---|---|
| Chimney cap installation | $300 – $900 |
| Chimney crown repair | $450 – $1,200 |
| Chimney liner installation | $2,500 – $5,000+ |
Do I need a full liner replacement or can HeatShield work?
HeatShield is a cerfractory sealant we apply when flue tiles are cracked but the liner structure is still intact. If tiles are collapsed, separated, or missing in large sections, a full DuraFlex stainless liner is the only safe repair. We’ll show you camera footage before recommending either option.
Will chimney repair require a permit in San Marino?
Many exterior chimney repairs in San Marino fall under the city’s preservation review, especially on older estates. Liner replacement done from inside the flue may not require structural review, but crown and masonry work often does. We’ll help you determine what applies before any work begins.

We work with a curated set of professional chimney-industry brands, including DuraFlex flexible stainless liner systems, HeatShield cerfractory sealant, and components from Olympia Chimney and Copperfield.
