Why Hearthstone Chimney Co. of Los Angeles Is North Hills’s Preferred Chimney Repair Company
We’ve worked on chimneys in the 91343 and 91393 ZIP codes for over 42 years. That longevity matters in a neighborhood where the housing stock is aging and the repair history is complicated. North Hills sits immediately adjacent to the 1994 Northridge earthquake epicenter, and the neighborhood’s large stock of post-WWII masonry chimneys absorbed severe seismic stress. Many were hastily repointed or partially rebuilt in 1994-1995, and those now-30-year-old repairs are cracking, spalling, and separating. Our Level-2 camera inspections routinely uncover concealed earthquake-era structural failures that neighboring Valley cities farther from the epicenter simply don’t see at the same rate.
Gil Mercer started this company in 1984, and we’ve built our reputation on showing homeowners exactly what we find. Every inspection ends with photos you can see and a plain-English verdict. Our technicians are background-checked, uniformed, and carry professional-grade materials from DuraFlex, HeatShield, and Copperfield on every truck. Most jobs are completed in a single visit. The number on your estimate is the number on your invoice. And everything we do is backed by our 90-Day Done Right Promise, in writing, with no arguing.
Our Chimney Repair Services in North Hills
Mortar Repointing
The 1950s-through-1970s ranch homes that dominate North Hills were built with mortar joints that have now endured 50 to 70 years of San Fernando Valley heat cycles and multiple earthquakes. We grind out deteriorated mortar to a proper depth and repoint with Type N mortar formulated for seismic zones, not the quick-setting bag mixes a handyman might grab at the hardware store. In North Hills, we regularly find original mortar that has turned to sand, or worse, 1994-era repairs that used the wrong mortar type and are now failing again.
Spalling Brick Repair
Spalling, where the face of a brick flakes or pops off, is common on North Hills chimneys that were saturated during winter rains then baked by summer sun. The freeze-thaw cycle is mild here, but the thermal shock is real. We remove spalled bricks and replace with matching units, or when the damage is extensive, we rebuild the affected courses. Our techs carry common brick sizes and profiles to avoid a second trip down those long North Hills driveways.
Chimney Waterproofing
The semi-arid climate in North Hills tricks homeowners into thinking their chimneys don’t need waterproofing. They do. Long dry summers allow tiny cracks to open in crowns and mortar joints. When the winter rains arrive, water enters those cracks, and the next heat cycle widens them. We apply vapor-permeable sealers from professional-grade lines that let the chimney breathe while blocking water intrusion. This is especially important on homes near the hills where wind-driven rain hits harder.
Flashing Repair
Flashing at the roof-chimney intersection is a common leak point on North Hills’s low-slope ranch roofs. We see original flashing that was never properly stepped or counter-flashed, or that was damaged during reroofing jobs where the contractor reused old material. We fabricate custom flashing on site using proper materials and techniques, and we document the repair with photos for your records.
Chimney Rebuilding
When a North Hills chimney has sustained structural damage from the ’94 quake, decades of deferred maintenance, or a combination of both, partial or full rebuilding is the only sound option. We dismantle only what is necessary, salvage usable brick where possible, and rebuild to current standards with proper reinforcement and flue sizing. Most rebuilds in North Hills are completed in three to five days, and we protect the work area throughout.
Tuckpointing
Tuckpointing is the fine-art cousin of standard repointing, used where aesthetic matching matters on visible chimney faces. On North Hills homes with prominent street-facing fireplaces, we color-match mortar and tool joints to blend with original construction. The result is a repair that does not advertise itself.

Trusted Brands We Service in North Hills
We stock parts and materials from DuraFlex, HeatShield, and Copperfield on every service truck, which means North Hills homeowners don’t wait for special orders. HeatShield’s cerfractory flue liner system is particularly valuable here, where we encounter fireboxes compromised by the ’94 quake and patched with materials that were never meant to withstand combustion temperatures. Having the right product on the truck allows us to complete the repair in one visit, even on properties with long service drives where a callback is a genuine inconvenience.
Common Chimney Repair Problems We See in North Hills Homes
- Handyman caulk patches from the 1990s crack open again, venting combustion gases into wall cavities. We recently repaired a 1955 ranch off Parthenia Street where a homeowner had ignored a rattling firebox door for years. Our tech pulled the panel and found the classic ’94 stepped crack patched with ordinary caulk, now open and leaking carbon monoxide into the living room. We installed a HeatShield ceramic liner, repointed the entire stack with Type N mortar, and capped the flue to keep out Santa Ana downdrafts, all in one trip, no callbacks.
- Settling on acreage lots misaligns flue tiles, causing smokey downdrafts during Santa Ana wind events. North Hills’s larger lots with detached workshops and outbuildings often have chimneys built on fill or cut slopes that have continued to settle. The resulting flue misalignment is invisible from the ground but obvious when smoke backs up into the room on a windy day.
- Long service drives on rural properties lead to incomplete repairs when techs run out of materials. Our one-trip policy prevents this. We stock for the worst case, not the best.
- SCAQMD Rule 445 wood-burning curtailment days compress actual burning into short permitted windows, which accelerates creosote layering during those brief active periods. This concentrated use pattern stresses already-compromised flue systems.

FAQs - Chimney Repair in North Hills
The 1994 Northridge earthquake epicenter was adjacent to North Hills, and the seismic waves created a distinctive stepped diagonal crack pattern in masonry fireboxes that is rare in cities farther from the fault rupture. Many were patched with non-refractory caulk by handymen in 1994-1995, and that material has now hardened, shrunk, and failed, reopening the crack and allowing combustion gases to vent into wall cavities. If your home was built before 1995 and the firebox has never been professionally inspected, we recommend a Level-2 camera inspection. Call (844) 418-0954 to schedule, estimates are free.
Yes, almost certainly if the repair was done in 1994-1995 and has not been inspected since. The post-quake repair boom in North Hills was marked by speed over quality, and we regularly find caulk patches, wrong mortar types, and partial rebuilds that were never properly flashed or lined. A 30-year-old repair on a 60-year-old chimney is not a permanent solution. We document what we find with photos and give you a plain-English verdict on what needs attention now versus what can be monitored. Call (844) 418-0954 for a free second opinion on any written estimate.
A full rebuild means dismantling the chimney to the roofline or below, inspecting the structure beneath, and reconstructing with proper materials, reinforcement, and flue sizing for your appliance. In North Hills, this typically takes three to five days and costs $5,500 to $8,500 depending on height, brick matching requirements, and accessibility. We salvage original brick when possible for aesthetic continuity, and we install a proper crown, cap, and flue liner as part of the job. The result is a chimney built to current standards, not pre-1970s practice. Call (844) 418-0954 for an exact quote, estimates are free.
A leaning or separated chimney indicates foundation or structural failure and requires immediate professional evaluation. In North Hills, this is often earthquake-related or caused by long-term settling on acreage lots with fill soils. We stabilize the chimney, address the underlying cause, and rebuild as needed. This is not a DIY project, the weight of masonry and the risk of collapse or gas leakage require trained technicians. Call (844) 418-0954 and we will prioritize the inspection.
Santa Ana winds create positive pressure on the leeward side of a house, forcing air down the flue and causing downdrafts that push smoke and combustion gases into living spaces. In North Hills, this effect is amplified on hillside properties and homes with damaged or missing chimney caps. A properly sized cap, intact flue liner, and correct chimney height relative to the roof ridge are the standard defenses. We inspect for all three during every Level-2 evaluation. Call (844) 418-0954 to schedule, estimates are free.
