We’ve been driving to Covina since 1984, long enough to know the difference between a home off Citrus Avenue and one up against the foothills near Azusa. Our technicians carry Level-2 camera rigs, stainless steel liners from DuraFlex and Olympia Chimney, and the masonry supplies for partial or full rebuilds. We stage our trucks for one-trip completion because Covina homeowners have told us plainly: they don’t want to take two days off work for a chimney job.
Why Hearthstone Chimney Co. of Los Angeles Is Covina’s Preferred Chimney Liner & Rebuild Company
Our reputation in Covina was built on the eastside blocks near Barranca Avenue, where we’ve documented dozens of earthquake-damaged clay liners that homeowners never knew were cracked. We show you the photos. We give you a plain-English verdict. And we put our 90-Day Done Right Promise in writing with no arguing - if it’s not right, we come back. Gil Mercer has run Hearthstone with that standard since 1984.
When you call (844) 418-0954, a live person answers. Not a voicemail, not a callback queue. Our background-checked, uniformed technicians arrive when we say we will, and most Covina liner and rebuild jobs finish in one visit. No-hassle upfront pricing means the number on your estimate matches the number on your invoice.
We know Covina’s permit process at City Hall, the typical footing depths in the 91722 and 91724 ZIP codes, and the way South Coast AQMD Rule 445 shapes how often residents actually use their fireplaces. That local knowledge saves you time and prevents surprises.
Our Chimney Liner & Rebuild Services in Covina
Stainless Steel Liner Installation
Stainless steel liners are our most common solution for Covina’s original clay flue tiles. A 6-inch DuraFlex or Olympia Chimney stainless liner slides into the existing chimney structure, creating a sealed combustion path that contains gases even when the surrounding clay is cracked. For Covina homes shaken by the 1987 Whittier Narrows quake, this is often the difference between a safe fireplace and one leaking carbon monoxide into wall cavities. We size, cut, and install on-site in one trip.
Flexible Liner Systems
Some Covina chimneys - especially the older ranch homes with offset flue sections near Vincent or Charter Oak - need a flexible liner that can navigate bends without breaking the draft. We use professional-grade flexible stainless from DuraFlex, rated for the temperature swings these chimneys see when AQMD no-burn days interrupt regular use. Flexible liners cost roughly the same as rigid in materials but save labor on complex flue geometries.
Liner Replacement
When a clay liner is shattered, spalled, or missing sections entirely, partial or full replacement is the only safe option. In Covina’s 91723 ZIP code, we’ve replaced liners in homes where the original 1960s clay had simply disintegrated from decades of thermal cycling - heavy use on cold nights, then weeks of dormancy. We remove the damaged sections, inspect the surrounding masonry with our camera, and install new liner matched to your appliance’s BTU output.
Partial and Full Chimney Rebuild
When the chimney structure itself is compromised - leaning, separating from the house, or showing mortar failure through multiple courses - a liner alone won’t solve it. Our Chimney Liner & Rebuild crew handles partial rebuilds of the firebox and smoke chamber, or full teardowns and reconstructions when the stack is unsound. In Covina, we see this most often on homes where the 1994 Northridge quake finished what 1987 started. Full rebuilds in Covina typically run $3,500-$8,500 depending on height, access, and whether the footing needs reinforcement.

Trusted Brands We Service in Covina

We keep common diameters and fittings on our trucks so we’re not ordering parts and making you wait. When a Covina homeowner calls, we intend to finish the job before we leave.
Common Chimney Liner & Rebuild Problems We See in Covina Homes
- Hidden earthquake cracks: Hairline fractures from the 1987 Whittier Narrows or 1994 Northridge quakes run through clay liners invisible from the firebox. Our Level-2 camera inspection finds them. We replaced the shattered clay liner in a 1963 ranch home on Barranca Avenue with a 6-inch DuraFlex stainless steel liner after a camera inspection revealed three offset sections - a classic signature of the Whittier Narrows quake. The homeowner had no idea combustion gases were leaking into his attic, and we completed the entire liner and rebuild in one trip thanks to our pre-staged truck setup.
- Animal blockages: Dormant flues on AQMD no-burn days become nesting sites for roof rats and birds. We’ve pulled nests from Covina chimneys that completely blocked the flue, creating smoke backup hazards and fire risks on the first cold night.
- Mortar spalling from thermal cycling: Heavy single-day fireplace use followed by weeks of dormancy - the Covina pattern, thanks to burn restrictions - accelerates mortar joint deterioration. Spalled mortar leads to structural instability and liner failure.
- Offset clay sections: Technicians working Covina’s older eastside blocks near Barranca Avenue commonly find brick chimneys that look intact from the roofline but hide offset or shattered clay liner sections - earthquake damage most homeowners have never been told about.

FAQs - Chimney Liner & Rebuild in Covina
More common than most homeowners realize, especially in homes built before 1980. The 1987 Whittier Narrows earthquake epicentered roughly 12 miles southwest of Covina, and its fault movement ran directly under the eastern San Gabriel Valley. We’ve found offset or shattered clay liner sections in dozens of Covina homes where the brick looked fine from the outside. A Level-2 camera inspection is the only way to know for certain. Call (844) 418-0954 to schedule - estimates are free.
Yes, if the surrounding masonry structure is still sound. A stainless steel liner creates a new, sealed combustion path inside the existing chimney, containing gases even when the original clay is cracked or offset. We use DuraFlex and Olympia Chimney liners rated for this exact application. If the chimney structure itself is leaning or separating, a full or partial rebuild is required first. We’ll tell you which situation applies after our camera inspection.
No. South Coast AQMD Rule 445 restricts wood-burning on no-burn days, but it does not restrict chimney repair or liner installation work. In fact, the off-season is often the best time to schedule liner work in Covina - our calendar opens up, and you’ll have a safe, inspected system ready when the first cold night arrives. We work year-round.
Yes. The City of Covina requires a building permit for any structural chimney work beyond liner installation. We handle the permit application as part of our project scope, including the drawings and inspections required by Covina Building & Safety. Most permits for residential chimney rebuilds in Covina are issued within 5-10 business days. We’ll give you the exact timeline when we quote.
We install DuraFlex and Olympia Chimney stainless steel liners, and we use HeatShield cerfractory sealant for resurfacing applications where the clay is sound but porous. These are professional-grade products with published alloy specifications and manufacturer warranties - not builder-grade substitutes. We stock the common diameters for Covina’s original ranch-home fireplaces so most jobs finish in one visit.
