San Fernando sits in a tough spot for masonry. The 1971 Sylmar earthquake was centered just north of the city limits, and the 1994 Northridge quake struck nearby. Decades of seismic stress have left many of the city’s older masonry chimneys with cracked or offset flue tiles and failed mortar joints that are invisible from the exterior but create serious fire and CO hazards. We’ve been working on chimneys in this corridor since 1984, and we’ve learned that San Fernando homes need camera inspections, not just Chimney Cleaning & Sweep - San Fernando.
Why Hearthstone Chimney Co. Is San Fernando’s Preferred Chimney Repair Company
We’ve been driving to San Fernando since before the 210 freeway was finished. Over 42 years, we’ve repointed mortar on Spanish Colonial Revival bungalows near Maclay Avenue, rebuilt earthquake-shifted stacks in the neighborhoods off Truman Street, and replaced rusted flashing on post-war homes around the 91340 zip code. Our technicians know the difference between a chimney that looks sound and one that actually is.
San Fernando homeowners call us back because we document what we find. Every Level-2 inspection ends with photos you can see and a plain-English verdict. No jargon, no scare tactics. If the flue tiles are cracked after fifty years of thermal cycling, we’ll show you. If the mortar is sound for another decade, we’ll say that too.
A live person answers our phones 24 hours a day, 7 days a week. Not a voicemail, not a callback queue. When water is dripping through your ceiling during a Santa Ana windstorm, you reach someone who can dispatch a crew.
Our 90-Day Done Right Promise applies to every job in San Fernando. If it’s not right, we come back. In writing, no arguing.
Our Chimney Repair Services in San Fernando
Mortar Repointing
The hard water in San Fernando accelerates mortar decay, and the pre-1960 housing stock near San Fernando Mission Boulevard was built with lime-based mortars that don’t hold up to decades of thermal expansion. We grind out failed joints to proper depth and repoint with color-matched, professional-grade mortar from Copperfield. A typical repointing job on a San Fernando bungalow runs $450-$1,200 depending on access and how many courses need work.
Spalling Brick Repair
Spalling - when brick faces flake off from freeze-thaw cycling or moisture intrusion - is common on San Fernando chimneys that were “repaired” after the 1971 or 1994 earthquakes with exterior tuck-pointing only. The visible mortar looks fine, but water got in through cracks that were never addressed. We remove spalled units, install matching replacement brick, and seal with breathable water repellent. Most spalling repairs in the 91341 area cost $800-$2,200.
Chimney Waterproofing
Santa Ana winds drive rain sideways into masonry that standard house paint can’t protect. We apply vapor-permeable sealers from HeatShield that let the chimney breathe while blocking water entry. For San Fernando’s inland valley chimneys, which sit unused through hot summers then face cold winter nights in the mid-30s, this breathing room matters. Waterproofing a typical San Fernando chimney runs $650-$1,400.
Flashing Repair
The junction where your chimney meets the roof is the leak point we see most often in San Fernando’s older neighborhoods. Original flashing on 1940s homes was often galvanized steel that rusted through decades ago. We fabricate and install custom step and counter flashing using DuraFlex components, sealed with high-temperature solder. Flashing repair in San Fernando typically costs $400-$950, with steep roofs or tile requiring additional access time.

Trusted Brands We Service in San Fernando
We stock professional-grade materials from DuraFlex, HeatShield, and Copperfield - no builder-grade substitutes. For San Fernando homeowners, this means we don’t order parts and make you wait. Our trucks carry the liners, sealants, and flashing components that match your existing system, so most repairs finish in one visit. We’ve used these brands long enough to know which product belongs on a 1920s Spanish chimney versus a 1950s tract home, and we choose accordingly.
Common Chimney Repair Problems We See in San Fernando Homes
- Hidden earthquake damage behind fresh tuck-pointing. After the 1971 and 1994 quakes, many San Fernando chimneys got cosmetic exterior repairs while the flue tiles inside remained cracked. Our camera inspections find what the eye cannot.
- Single-wyhe brick stacks with no liner. Most pre-1960 San Fernando homes were built with one layer of brick and a bare flue. These aging structures can’t handle modern appliance temperatures and are especially vulnerable to seismic cracking.
- Failed flashing on original roofs. Decades of Santa Ana wind and summer heat cycling have separated the flashing from roof decks across the city, particularly on homes near the 118 corridor.
- Creosote-compromised masonry from seasonal use patterns. San Fernando’s cold winter nights drive concentrated fireplace use, while chimneys sit dormant through hot summers. This start-stop cycle stresses mortar and collects acidic deposits.
