Fast, Reliable Chimney Repair Across Mission District
Chimney repair in Mission District typically runs $350-$2,800 depending on whether you need mortar repointing, a full rebuild, or liner installation, and our Chimney Repair team completes most jobs in a single visit. If you live in one of the Mission’s century-old Victorian or Edwardian flats, your chimney was likely built between 1890 and 1915 with original unlined brick masonry, often serving multiple fireplaces across stacked units. That construction is why we keep our trucks stocked with DuraFlex liners, HeatShield refractory mortar, and matching antique brick for rebuilds. Call (855) 408-5567 any hour - a live person answers, and we can usually inspect within 24 hours anywhere in 94110.
Why Hearthstone Chimney Co. of San Francisco Is Mission District’s Preferred Chimney Repair Company
We’ve worked Mission District chimneys for over 42 years. Warren Eckhart started this company in 1984, and our technicians know the difference between a flat on Valencia Street built in 1903 and one on Mission Street built in 1912 - not for nostalgia, but because the mortar mixes, brick dimensions, and flue configurations changed, and matching them matters for a repair that holds.
Our reputation here is built on documentation. Every inspection ends with photos you can see and a plain-English verdict. No jargon, no scare tactics. If your chimney needs work, we show you exactly where the mortar has failed or where the flue is compromised. If it doesn’t, we say so.
Response time to the Mission is same-day or next-day for urgent issues - a cracked crown during rainy season, a blocked flue, or a rental inspection deadline. We know the parking situation on narrow streets like Capp and Shotwell, and we schedule accordingly so we’re not double-parked with a ladder truck during rush hour.
Most importantly, we’re still going to be here in thirty years. That changes how we work. We don’t chase the cheapest fix. We do the one that lasts.
Our Chimney Repair Services in Mission District
Mortar Repointing
Mortar repointing in Mission District runs $450-$1,200 for a typical two-story flat chimney, with costs climbing if seismic damage has loosened multiple courses. The 1906 earthquake and subsequent tremors shook these buildings hard. We regularly find original lime mortar that has turned to powder between bricks on chimneys along Guerrero and South Van Ness. Our technicians grind out the failed mortar to proper depth - never the quick surface skim some crews do - and repoint with HeatShield or matching lime-based mortar that flexes with the building. Done right, and we stand behind it.
Spalling Brick Repair
Spalling - bricks flaking and crumbling from freeze-thaw cycling and moisture intrusion - is common on Mission chimneys where failed crowns let water sit. A typical spalling repair on a Mission flat runs $600-$1,800 depending on how many courses need replacement. We source matching antique brick when possible, or cut new brick to blend. The key is finding and fixing the water source first. Otherwise you’re repairing the same wall in three years.
Chimney Waterproofing
Mission District’s position east of Twin Peaks shelters it from the marine fog that blankets the Sunset, but the salt-laden air still reaches these chimneys, especially on roofs with bay exposure. Waterproofing a Mission chimney with professional-grade sealant runs $300-$650. We use breathable silane-siloxane formulas that let moisture escape while blocking new water and salt intrusion. Critical for extending the life of repointing work on century-old brick.
Flashing Repair
Flashing repair in Mission District costs $350-$850, with steeper roofs and multiple penetrations at the higher end. The combination of original wood-frame construction, decades of roof layers, and seismic movement means flashing pulls away from chimney saddles routinely. We use copper or coated steel flashing, never the thin aluminum that corrodes in salt air. Every flashing job gets integrated with the existing roofing to prevent the leaks that destroy ceiling plaster in these old flats.
Chimney Rebuilding
When mortar deterioration, spalling, and structural compromise converge, partial or full chimney rebuilding becomes necessary. In Mission District, a partial rebuild of a Victorian flat chimney typically runs $1,800-$3,500, while a full rebuild can reach $4,500-$7,500 depending on height, access, and whether we need to install a liner system. We dismantle only what’s unsound, salvage usable brick, and rebuild to current San Francisco code - including proper flue separation for multi-unit buildings. Our 90-Day Done Right Promise covers every rebuild in writing, no arguing.
Tuckpointing
Tuckpointing in the Mission serves a different purpose than standard repointing - it’s the cosmetic matching of mortar color and profile to preserve the historic appearance of these Victorian facades. For Mission District properties in historic review areas or simply where appearance matters, tuckpointing runs $550-$1,400. We color-match existing mortar precisely, maintaining the architectural character that makes these buildings distinctive.

Common Chimney Repair Problems We See in Mission District Homes
- Shared, unlined flues in pre-1920 Mission flats accumulate sticky Stage-2 creosote quickly due to infrequent, low-intensity fires. The Mission’s warm, fog-sheltered climate means residents burn far less than west-side neighbors, but those short, occasional fires never get hot enough to burn off residue. The result is dangerous, glazed creosote that standard brushing won’t remove.
- Salt-laden coastal air from the nearby bay accelerates corrosion of cast-iron dampers and metal components. Even though Mission residents burn rarely, the hardware still deteriorates. We replace failed dampers with stainless or coated units that resist corrosion.
- Seismic stress from the 1906 earthquake and subsequent tremors causes mortar deterioration and spalling in original brick chimneys. The cumulative effect of 120 years of small tremors on unreinforced masonry shows up as stair-step cracks, loose courses, and bricks that sound hollow when tapped.
- Original chimney crowns cracked from thermal cycling and water infiltration. Most Mission flats still have the original poured concrete crown, now thin and cracked, funneling water directly into the masonry below. Crown repair or replacement is often the first domino in preventing larger rebuilds.

The Mission District’s Unique Chimney Challenge: Shared Flues in Century-Old Buildings
In the Mission District, chimney repair often involves century-old unlined brick flues shared by multiple units in Victorian flats, a configuration that predates modern safety codes and is increasingly flagged by SF rental inspectors. The majority of these buildings went up between 1890 and 1915, largely spared by the 1906 earthquake, and their chimneys were never designed for modern heating appliances or separate tenant use. Two or three fireplaces may feed into a single unlined brick chase with no separation between flues. That’s both a fire-code liability under San Francisco’s multi-unit building rules and a structural concern given cumulative seismic stress.
We recently repaired a shared flue on a 1908 Edwardian flat on 24th Street, where three fireplaces fed into one unlined brick chase. We installed a DuraFlex stainless steel liner to separate the flues and bring the unit into compliance with San Francisco’s multi-unit building rules, preventing a tenant complaint from shutting it down. The owner had forty-eight hours to respond to a habitability citation. We completed the liner installation and provided documentation for the inspector in one day.
This shared-flue situation is why Chimney Repair in Mission District cannot be separated from inspection. You cannot clean what you cannot see, and you cannot certify what you have not documented. Our Level-2 camera inspections photograph every inch of the flue interior and end with a plain-English verdict you can show your insurance, your tenant, or the city.

FAQs - Chimney Repair in Mission District
Mission District chimneys need more frequent repair because the neighborhood’s dense concentration of pre-1920 Victorian and Edwardian flats means most chimneys are original unlined brick masonry now exceeding 100 years of service, compounded by shared-flue configurations and cumulative seismic stress no other SF neighborhood matches in concentration. The 1906 earthquake and subsequent tremors loosened mortar in ways that continue to propagate. Call (855) 408-5567 for a free inspection - we’ll show you exactly what your chimney needs.
Salt-laden air from the bay accelerates corrosion of cast-iron dampers, metal flashing, and hardware even though Mission residents burn less frequently than west-side neighbors, meaning components deteriorate while owners assume light use equals slow wear. We replace failed dampers with stainless or coated units and use corrosion-resistant fasteners. A square deal: no surprises on the bill.
Yes, shared flues are common in Mission Victorian flats and they are a significant problem - multiple fireplaces or heating appliances exhausting into one unlined brick chase creates cross-contamination risk, draft interference, and fire-code violations under San Francisco’s multi-unit building rules. SF rental inspectors are increasingly flagging this configuration during habitability reviews. Separation with individual liners is the standard repair. Call (855) 408-5567 - estimates are free.
The most common repair is mortar repointing combined with crown sealing or replacement, because century-old lime mortar has degraded and original concrete crowns have cracked, allowing water to accelerate both spalling and structural loosening. Most Mission repointing jobs run $450-$1,200. We’ll be there when we say.
An unlined brick flue in a Mission District multi-unit building should be inspected annually at minimum, and immediately if you receive any rental inspection notice, tenant complaint, or notice of violation from the city. Shared flues accumulate creosote faster than single-use lined flues, and the consequences of a fire or blockage citation in a rental unit are severe. Our Level-2 camera inspection with photos and written verdict runs as part of our standard service. Call (855) 408-5567 to schedule - a live person answers 24/7.
