At Hearthstone Chimney Co., we’ve been fixing chimneys across Los Angeles since 1984, and our background-checked, uniformed technicians carry the professional-grade materials to handle most repairs same-day without a return trip. Call (844) 418-0954 and you’ll reach a live person, 24 hours a day, 7 days a week - no voicemail, no callback queue.
Los Angeles chimneys take a beating that homeowners in milder climates don’t face. The Santa Ana winds drive rain sideways into mortar joints. Thermal shock from 100-degree days followed by 50-degree nights stresses brick and stone year after year. And the 1994 Northridge earthquake left thousands of chimneys across the San Fernando Valley, Pasadena, and Mid-City with hairline cracks that have widened over three decades. We’ve seen it all twice. In Silver Lake, we regularly find spalling brick caused by decades of sun-baked mortar that’s turned to powder, which is why homeowners there rely on our Best Chimney Repair in Los Angeles, CA. In the Hollywood Hills, chimney crowns have eroded to nothing after forty years without maintenance. Our Level-2 camera inspections end with photos you can see and a plain-English verdict - documented like an engineer, explained like a craftsman. Gil Mercer, who leads Hearthstone Chimney Co., started this company on the principle that a square deal means no surprises on the bill. That hasn’t changed in 42 years.
What Our Chimney Repair Service Includes
Mortar Repointing
Mortar repointing is the process of grinding out deteriorated mortar between bricks and packing fresh, matched mortar into the joints. In Los Angeles, we see this need most often in homes built before 1980 where the original lime mortar has simply turned to dust after decades of heat cycling and occasional seismic stress. Our technicians use professional-grade mortar mixes color-matched to your existing brick, and we complete most repointing jobs in a single visit because we stock the full range of masonry tints and aggregates.
Spalling Brick Repair
Spalling occurs when water penetrates brick, freezes in any micro-crack, and flakes off the face of the brick - a problem that accelerates in Los Angeles when morning marine layer moisture gets trapped behind failing chimney crowns. We see severe spalling regularly in beach-adjacent neighborhoods like Venice and Playa del Rey, but also in inland areas where sprinkler systems hit chimney bases daily. Hearthstone removes damaged bricks, sources matching replacements from local suppliers who stock vintage California common brick, and rebuilds the affected courses with the same care we’d use on our own homes.
Chimney Waterproofing
Chimney waterproofing applies a vapor-permeable sealant that blocks liquid water while allowing trapped moisture to escape - critical in Los Angeles where El Niño seasons can deliver 30+ inches of rain in concentrated bursts. We use professional-grade waterproofing compounds from Olympia Chimney and Famco, applied after thorough cleaning and any necessary mortar repair. In hillside neighborhoods from Los Feliz to Mount Washington, where chimneys catch full afternoon sun followed by evening fog, proper waterproofing can add fifteen years to a chimney’s service life.
Flashing Repair
Flashing is the metal barrier where your chimney penetrates the roof, and it’s the single most common leak point we find in Los Angeles homes. The combination of intense UV exposure and thermal expansion eventually cracks solder joints and pulls step-flashing away from the brick. We repair flashing using professional-grade materials from Gelco and Copperfield, and where replacement is needed, we fabricate custom pieces on-site rather than forcing stock sizes that won’t seal properly. In our experience, improper flashing installation by general roofers - not chimney specialists - causes more leaks than age itself.
Chimney Rebuilding
Partial or full chimney rebuilding becomes necessary when structural integrity is compromised - after major seismic events, when multiple courses have spalled through, or when the chimney has separated from the house wall. We’ve rebuilt chimneys from the roofline up in historic neighborhoods like Hancock Park and West Adams, matching original architectural details while bringing the structure to current Los Angeles building code. Every rebuild includes a new crown, proper flashing integration, and your choice of cap from our professional-grade inventory. The 90-Day Done Right Promise covers the full rebuild - in writing, no arguing.
Tuckpointing
Tuckpointing is the refined cousin of standard repointing, used when aesthetic precision matters - typically in historic Los Angeles homes where the original fine-line mortar joints are part of the architectural character. Our technicians grind to precise depths and apply two contrasting mortar colors to recreate the “ribbon” effect common in Craftsman and Spanish Colonial Revival chimneys. We’ve tuckpointed chimneys in Pasadena’s Bungalow Heaven and the historic core of Angelino Heights, where preservation standards demand workmanship that disappears into the original fabric.

Brands We Service for Chimney Repair
We’ve installed and repaired thousands of systems using HeatShield ceramic refractory coating, a product we trust for resurfacing deteriorated clay flue liners without full replacement. In Los Angeles, where many 1920s-1950s homes have original terra cotta liners that have cracked from thermal cycling or minor seismic movement, HeatShield allows us to restore a smooth, safe flue passage at a fraction of rebuild cost. We stock the full application system and our technicians are trained in the specific curing requirements that Los Angeles humidity demands.
Gelco chimney caps and Famco venting components round out our most frequently specified brands. Gelco’s stainless steel caps withstand the salt air that reaches deep into Los Angeles from the Pacific, and we’ve found their mesh designs particularly effective at keeping out the aggressive roof rats common to hillside neighborhoods. Famco’s galvanized and stainless product lines give us reliable options for every budget without dropping to builder-grade substitutes. Whether you have HeatShield, Gelco, Famco, or any other make, we can help. Our trucks carry the fittings and expertise to repair what exists or upgrade to something that lasts.
Signs You Need Chimney Repair Right Now
- White staining (efflorescence) on exterior brick means water is moving through your masonry and depositing salts as it evaporates. In Los Angeles, this often first appears on the north-facing side of the chimney where morning fog lingers longest. Left alone, the same water migration that carries those salts is silently destroying mortar from within.
- Chunks of brick or mortar in your fireplace or on the roof below the chimney indicate active material failure, usually from spalling or deteriorated crown allowing water into the structure. We find this most often after the first serious rain of winter in homes from Eagle Rock to Crenshaw, when homeowners finally look up and notice what’s been crumbling since summer.
- Rust stains on the chimney face or fireplace surround signal that metal components - the damper, firebox, or liner - are corroding from moisture intrusion. Los Angeles may be dry overall, but a leaking chimney creates its own microclimate of sustained dampness that destroys steel in two to three years.
- A chimney that leans or has visible separation from the house wall is a structural emergency requiring immediate professional assessment. The expansive soil common to Los Angeles basin neighborhoods, combined with any seismic history, can undermine foundations or break chimney ties. We’ve stabilized leaning chimneys in Koreatown and Mid-Wilshire before they became collapses.
- Damp or musty odors from the fireplace even in dry weather mean water is entering somewhere and not evaporating properly, often because a failed crown or deteriorated flashing is funneling moisture directly into the structure. In Los Angeles homes with air conditioning, that trapped moisture creates conditions for mold growth that spreads beyond the chimney itself.
Our Chimney Repair Process - Step by Step

Schedule by phone with a live person. Call (844) 418-0954 any hour, any day. We’ll ask about your chimney’s age, symptoms you’ve noticed, and your neighborhood in Los Angeles - this lets us dispatch the technician with the right materials already loaded. No automated scheduling, no app to download.

How Much Does Chimney Repair Cost in Los Angeles?
A typical mortar repointing job on a standard Los Angeles chimney runs $800-$1,800 depending on how many courses need attention and whether scaffolding is required for two-story homes common in Los Feliz or the Hollywood Hills, making our Affordable Chimney Repair in Los Angeles, CA a smart choice for these neighborhoods. Spalling brick repair starts around $1,200 for localized replacement but can reach $3,500 when multiple faces are involved and vintage matching is needed. Chimney waterproofing generally falls between $450-$950 for application after any necessary prep, with larger commercial-style chimneys in neighborhoods like Hancock Park running toward the higher end. Flashing repair ranges from $350 for straightforward sealant and fastener replacement to $1,800 when custom fabrication and roof shingle integration is required. Partial chimney rebuilding - from the roofline up - typically costs $2,800-$4,500 in Los Angeles, while full rebuilds of exterior chimneys on older homes can exceed $8,000.
Several factors move these numbers. Access difficulty matters: chimneys on steep Los Angeles hillsides or behind dense landscaping require more labor hours. Material matching for historic homes adds cost but protects property value. And the extent of hidden damage - what we find once deteriorated facing is removed - can expand scope. You avoid overpaying by getting a detailed, itemized estimate before work begins, which is exactly what our free estimates provide. Every estimate includes the full scope, material specifications by brand, labor breakdown, and final price. No “plus materials” vagueness, no open-ended hourly rates. Call (844) 418-0954 for your exact quote - estimates are free, and our senior and veteran discount saves an additional 5% on every repair.
