Chimney Repair in Granada Hills, CA
Granada Hills sits just a few miles from the epicenter of the 1994 Northridge earthquake — one of the costliest natural disasters in US history. Chimney damage was among the most widespread structural effects throughout the San Fernando Valley, and many of those repairs were done hastily or not at all. Three decades later, Granada Hills chimneys are still showing the effects: mortar joints that were compromised in 1994 and never repointed, liner cracks that have been widening slowly ever since, and chimney-to-framing separations that a visual inspection from the ground won’t reveal.
Add to that the valley’s genuine temperature swings — cold enough in winter that Granada Hills residents actually use their fireplaces, hot enough in summer to accelerate thermal degradation — and a housing stock that’s predominantly original masonry from the 1950s through 1970s, and you have a neighborhood with more deferred chimney maintenance than most of Los Angeles.

Chimney Repairs We Handle in Granada Hills
Seismic Damage Repair
Given Granada Hills’ proximity to the Northridge epicenter and ongoing seismic activity from the San Andreas and associated fault systems, seismic damage assessment is one of the most important chimney services we provide in this area. Ground movement causes chimney structures to separate from home framing, develop internal liner cracks, and shift in ways that aren’t visible from the exterior. A Level 2 camera inspection is the only way to assess the flue interior for seismic damage. We stabilize separating structures, reline compromised flues, and rebuild chimney sections where movement has gone beyond repair. Written documentation is provided for insurance purposes.
Chimney Crown Repair & Replacement
Granada Hills’ combination of hot summers, cool winters, and periodic seismic activity is hard on chimney crowns. Thermal cycling expands and contracts the crown through each season while ground movement introduces stress fractures. Crowns on the area’s older homes were frequently built without proper slope or with insufficient overhang, accelerating water entry. We repair damaged crowns, rebuild improperly formed crowns from scratch, and seal with flexible elastomeric coating that accommodates the ground movement common in the San Fernando Valley.
Mortar Repointing & Masonry Repair
Granada Hills was developed heavily in the 1950s and 1960s, and the original masonry chimneys on these homes have had decades of thermal cycling and seismic stress to open their mortar joints. Once mortar fails, water enters with every rain and the deterioration accelerates. We repoint deteriorated joints using materials matched to the original, repair or replace displaced and spalling brick, and rebuild sections where structural integrity has been lost.
Chimney Liner Repair & Relining
Clay tile flue liners on older Granada Hills chimneys are frequently cracked — from seismic activity, from decades of thermal cycling, or both. A damaged liner allows combustion gases to escape into the chimney structure, creating both a fire hazard and a carbon monoxide risk. We repair damaged tile liners where targeted repair is viable and install stainless steel liner systems for chimneys requiring full relining. Relining is also required when converting a wood-burning fireplace to a gas insert.
Chimney Flashing Repair
Flashing failure is a common source of water intrusion throughout the San Fernando Valley, particularly after the thermal expansion cycles of a hot Granada Hills summer followed by the cooler, wetter winter months. We replace corroded or failed flashing, reseal existing flashing where the metal is still sound, and waterproof the surrounding masonry on all residential roofing types.
Prefabricated Chimney Repair & Replacement
Homes built in Granada Hills through the 1970s and 1980s often have prefabricated factory-built chimney systems alongside or instead of masonry construction. These systems have a finite service life, and components installed 40 or 50 years ago — refractory panels, housing, chase covers, and liner systems — are frequently at or past end of life. We repair and replace prefabricated chimney components and handle full system replacements when individual repair is no longer practical.
Chimney Cap Installation & Replacement
The Santa Ana winds that sweep through the San Fernando Valley make a properly secured chimney cap more important in Granada Hills than in most LA neighborhoods. A missing or loose cap during a high-wind event allows embers, debris, and wind-driven rain directly into the flue. We install stainless steel and copper caps properly sized for each flue and anchored to withstand valley wind conditions.
Chimney Leak Repair & Waterproofing
Water staining on interior walls near the fireplace, moisture in the firebox after rain, or a musty smell from an unused chimney all point to active water intrusion. We locate the entry point and repair it at the source. We also apply professional-grade masonry waterproofing to exterior chimney surfaces to prevent future moisture penetration.
Common Signs Your Granada Hills Chimney Needs Repair
- White efflorescence staining on exterior chimney brick
- Visible cracks in the chimney crown
- A gap between the chimney exterior and the house wall — a seismic separation sign
- Water or moisture in the firebox after rain
- Spalling, crumbling, or displaced brick
- Smoke entering the room when the fireplace is in use
- A musty or smoke odor when the fireplace isn’t running
- Rust staining around the chimney cap
Any of these is worth a call before using the fireplace again.

Frequently Asked Questions
My home is from the 1950s or 60s. What chimney issues should I expect?
Original masonry chimneys from this era in Granada Hills most commonly have deteriorated mortar joints, cracked clay tile liners, failed or undersized crowns, and seismic damage from the 1994 Northridge earthquake that may never have been properly repaired. A Level 2 inspection with camera documentation is the right starting point.
Do I need a post-earthquake inspection even if the chimney looks fine?
Yes. Seismic damage to flue liners and chimney-to-framing connections is frequently invisible from the exterior. The 1994 Northridge earthquake caused widespread internal chimney damage throughout the San Fernando Valley — including in homes where the exterior masonry appeared intact. A Level 2 camera inspection is the only way to assess the flue interior.
My home has a prefabricated chimney. Can you repair it?
Yes. We repair and replace components on all prefabricated factory-built chimney systems. If the system is beyond the point where individual component repair makes sense, we handle full system replacements as well.
Do you need to do an inspection before making repairs?
In most cases, yes. An inspection identifies what’s actually damaged so we address the root cause rather than a symptom. For straightforward repairs like a missing cap, inspection and repair can often happen in the same visit.
Do I need an inspection after an earthquake?
Yes — especially for prefabricated systems. Seismic activity causes shifting and separation that isn’t visible externally. A post-earthquake inspection is standard practice before resuming use of any fireplace system.
How long does chimney repair take?
Most targeted repairs — crown work, cap replacement, flashing, repointing — are completed in a single visit of two to four hours. More extensive work like full relining or structural rebuilding may require a follow-up visit. We’ll give you a clear timeline with the written estimate.
