Why Hearthstone Chimney Co. of Los Angeles Is Van Nuys’s Preferred Chimney Repair Company
We’ve worked on chimneys along Vanowen Street, Victory Boulevard, and the neighborhoods near Woodman Avenue long enough to know which 1950s tract homes have the original clay flue tiles, which ones got zero-clearance inserts retrofitted in the 1980s, and how the Valley’s thermal inversion zone changes what “annual maintenance” actually means here.
Our reputation in Van Nuys is built on documentation. Every Level-2 camera inspection ends with photos you can see and a plain-English verdict. No jargon, no scare tactics. If your flue is cracked, we show you the crack. If your mortar is sound, we say so.

Our Chimney Repair Services in Van Nuys
Mortar Repointing
The bulk of Van Nuys was tract-developed in the 1950s and 1960s, leaving a dense inventory of 60-70-year-old masonry fireplaces with mortar joints that have endured thousands of thermal cycles. Sub-40°F winter nights followed by 100°F+ summer days expand and contract those joints until the mortar turns to powder. We grind out the deteriorated material to proper depth and repoint with color-matched, professional-grade mortar formulated for seismic and thermal stress. Done right - and we stand behind it.
Spalling Brick Repair
Spalling - the flaking and crumbling of brick faces - accelerates in Van Nuys because moisture trapped during winter inversions freezes in the pore structure, then expands under summer sun. We see this pattern repeatedly in the 91470 and 91496 ZIP codes, where older masonry sat damp and unused for weeks before a rare permitted burn night. Our Chimney Repair team removes spalled units, treats the substrate, and installs matching brick with proper weep and drainage detail so the repair lasts.
Chimney Waterproofing
Van Nuys receives minimal rainfall, but what little comes arrives in concentrated winter storms that saturate already-moist masonry. The South Coast AQMD’s No-Burn days leave flues cold and damp for extended periods, and that moisture migrates through porous brick into the living space or attic. We apply vapor-permeable waterproofing agents that let the chimney breathe while repelling liquid water - critical for a climate where drying opportunities are sporadic.
Flashing Repair
Valley wind patterns and thermal expansion separate chimney flashings from roof decks faster than in more temperate zones. We fabricate and install custom flashing using professional-grade materials, sealed with compounds rated for the temperature extremes this inland Valley produces. Every flashing repair includes inspection of the adjacent roof deck and sheathing - we don’t seal over rot.

Common Chimney Repair Problems We See in Van Nuys Homes
- Third-degree creosote glazing from compressed burn schedules. Van Nuys averages 20-plus winter No-Burn days per season. Homeowners who burn only on permitted nights often use cold, unprimed flues with unseasoned wood. Five such burns can deposit more stage-3 creosote than 30 moderate burns on a properly warmed system. We regularly need rotary chain whip cleaning before we can even inspect the flue.
- Thermal cycling damage to clay flue tiles. The inland Valley’s temperature extremes - sub-40°F winter nights followed by 100°F+ summer days - stress mortar joints and flue tiles harder than coastal Los Angeles neighborhoods just 15 miles south. Spalling and cracking accelerate accordingly.
- Moisture-driven flue deterioration during winter inversions. Cold, damp air trapped in unused flues for weeks promotes moss growth inside the stack and accelerates mortar decay before the season’s first fire is ever lit. We’ve removed moss colonies from flues that hadn’t burned in months.
- Mixed masonry-and-metal system complications. A secondary wave of mid-century owners retrofitted prefabricated zero-clearance inserts into original fireboxes. Our technicians must assess two completely different standards - masonry clearances and metal manufacturer specs - during the same service call. Missing this distinction is how house fires start.

FAQs - Chimney Repair in Van Nuys
Because five cold-start, high-moisture burns on an unprimed flue deposit more stage-3 creosote than 30 moderate burns on a properly warmed system. Van Nuys homeowners often burn only on rare permitted No-Burn exemption nights, using cold flues and sometimes unseasoned wood. The compressed schedule prevents the gradual, clean burning that would otherwise limit buildup. We recently repointed a 1950s masonry chimney on Vanowen Street near Woodman Avenue where exactly this pattern had glazed the flue so thick we needed a Chimney Cleaning & Sweep - Van Nuys with a rotary chain whip before inspection. Call (844) 418-0954 for a Level-2 camera inspection - estimates are free.
The inland Valley’s 60-degree-plus daily and seasonal thermal swings expand and contract clay flue tiles and mortar joints far more aggressively than in coastal LA, accelerating spalling, cracking, and joint failure. Sub-40°F winter nights followed by 100°F+ summer days constitute thousands of stress cycles over a chimney’s lifetime. We inspect for hairline cracks that haven’t yet opened fully but will after the next temperature swing. Catching them early is the difference between repointing and rebuilding.
Yes. Mixed masonry-and-metal systems require assessment against two completely different standards during the same service call - NFPA 211 for the masonry shell and the insert manufacturer’s clearance specifications for the metal unit. Many Van Nuys homes from the 1950s and 1960s received these retrofits, and improper clearances are a documented fire cause. Our Level-2 camera inspection documents both systems with photos you can see and a plain-English verdict. We do not guess when two code regimes apply.
We remove moss and treat the underlying moisture condition, then repair or Chimney Liner & Rebuild - Van Nuys depending on liner condition. Moss in a flue indicates prolonged dampness, typically from winter inversion trapping cold, moist air in an unused stack. The moss itself is a symptom; the cause is moisture management and possibly crown or flashing failure. We apply HeatShield refractory mortar for cracked liners or install DuraFlex stainless-steel relining systems when damage is extensive. Either way, we stop the water intrusion that enabled the growth.
We work exclusively with professional-grade materials from DuraFlex, HeatShield, Gelco, Olympia Chimney, Famco, and Copperfield - no builder-grade substitutes. For Van Nuys’s thermal cycling and moisture conditions, we typically specify HeatShield refractory mortar for liner restoration, DuraFlex stainless-steel components for chase covers and caps, and Olympia Chimney or Famco for ventilation and termination hardware. Every material is documented in your written report. If you have a preference or existing system from one of these manufacturers, we match and integrate accordingly. Call (844) 418-0954 to discuss your specific repair.
