Fast, Reliable Chimney Liner & Rebuild Across Monrovia
Chimney liner installation and rebuild work in Monrovia typically runs $2,800-$7,500 depending on whether we’re dropping a stainless steel liner into a sound flue or rebuilding from the roofline up after structural failure. Most of our Monrovia customers get their job scoped, priced, and scheduled in a single visit, with our Chimney Liner & Rebuild crew completing the majority of liner replacements in one day.
We’ve been driving out to Monrovia since 1984, and we know the difference between a 1920s Craftsman chimney on Canyon Boulevard and a 1970s tract flue off Huntington Drive. The foothill neighborhoods north of Foothill Boulevard sit in LA County’s Very High Fire Hazard Severity Zone, where an unlined or deteriorated chimney isn’t just a draft problem - it’s a code issue that can complicate your homeowner’s insurance after any incident. That’s why Monrovia residents call us at (844) 803-1545. We answer live, 24 hours a day, and we’ll give you a free estimate with numbers that don’t change on the invoice.

Our Chimney Liner & Rebuild Services in Monrovia
Stainless Steel Liner Installation
Monrovia’s original unlined brick chimneys - especially the 1910s-1940s stock in the Old Town radius - were never built for modern heating appliances. We install rigid and flexible stainless steel liners from Olympia Chimney and Famco, sized precisely to your appliance’s BTU output and your flue’s interior dimensions. In the Very High Fire Hazard Severity Zone above Foothill Boulevard, a properly listed stainless liner isn’t just good practice; it’s often the difference between passing inspection and getting flagged by your insurance adjuster. A typical stainless steel liner installation in Monrovia runs $2,800-$4,200.
Flexible Liner Installation
Older Monrovia chimneys with offset flues or tight cleanout passages - common in the steep-roofed bungalows near Colorado Boulevard - often can’t accept a rigid liner without extensive demolition. We use professional-grade flexible liners from DuraFlex that navigate offsets while maintaining the interior diameter your appliance needs. Cold air draining down Monrovia Canyon makes these homes burn wood more nights per year than flatland SGV neighbors, so the liner has to handle real creosote load, not just occasional holiday fires. Flexible liner installation in Monrovia typically costs $3,200-$4,800.
Liner Replacement
We’ve replaced more failed liners in Monrovia than we can count, and the pattern is consistent: a gas insert retrofit into an oversized, unlined masonry fireplace that never drafted right to begin with. The original clay tiles crack from thermal shock, or the corrugated “liner” installed by a handyman in the 1990s has rusted through at the water table. We pull the failed material, inspect the surrounding masonry with a camera, and install a new listed liner sized to the appliance - not the other way around. Liner replacement in Monrovia generally falls between $2,800-$5,500 depending on accessibility and whether the smoke chamber needs parging.
Partial Chimney Rebuild
Monrovia’s Santa Ana wind exposure, channeled through the canyon, scours mortar joints and drives water into freeze-thaw cycles that spall brick and dissolve lime mortar. A partial rebuild addresses the damage without tearing down sound structure below the roofline. We most commonly perform these on north-facing chimney breasts above Foothill Boulevard, where wind load and temperature swing are most severe. We match existing brick where possible and rebuild with proper crown slope and drip edge to shed water. Partial rebuilds in Monrovia start around $4,500 and can reach $7,500 if the smoke chamber or firebox requires reconstruction.

Trusted Brands We Service in Monrovia
We don’t use builder-grade substitutes, and we don’t special-order from a catalog you’ve never heard of. Our Monrovia trucks carry HeatShield refractory mortar for smoke chamber parging, Gelco stainless components for liner terminations, and Olympia Chimney and Famco liner systems in the diameters most common to local heating appliances. This means faster turnaround for you - most liner jobs don’t wait on parts. When a Monrovia customer calls with a failed liner or a spalling crown, we diagnose, specify, and execute with materials that carry proper UL listings and manufacturer backing. Done right, and we stand behind it.
Common Chimney Liner & Rebuild Problems We See in Monrovia Homes
- Original unlined flues in pre-war Craftsman homes. The historic residential core around Old Town is dense with 1910s-1940s bungalows still running their original brick flues. Without a liner, these chimneys leak combustion gases through eroded mortar joints and can’t safely handle modern gas insert BTU outputs.
- Gas insert retrofits into oversized fireplaces. A common Monrovia scenario: a homeowner installs a gas log set or insert into a massive, unlined masonry firebox. The flue is too large for the appliance, so it drafts poorly, condenses moisture, and collects debris - while the original clay liner continues to deteriorate unseen.
- Santa Ana wind debris and nesting material in open flues. Wind events channeled through Monrovia Canyon blow leaves, twigs, and nesting material directly into uncapped flue tops. Between burning seasons, this material blocks airflow and creates a fire hazard when the first cold night arrives.
- Spalled brick and failed mortar in foothill exposures. Chimneys north of Foothill Boulevard face sustained wind load and sharper temperature swings than flatland counterparts. Freeze-thaw cycling pops brick faces off and turns mortar to sand, especially on north and west exposures that stay wet longest.

We typically schedule Monrovia appointments within 24-48 hours, and same-day service is often available for active leaks or suspected liner collapse. Our technicians are already working throughout the San Gabriel Valley, so the drive to Monrovia - whether you’re near Old Town or up toward the canyon - is routine.

Yes, we work the full 91016 and 91017 area, from the flatland neighborhoods near Huntington Drive and Colorado Boulevard up to the canyon-adjacent streets north of Foothill. The foothill properties have specific code considerations - LA County’s Very High Fire Hazard Severity Zone designation - and we’re familiar with the inspection and documentation requirements those jobs involve.
A collapsed liner is an emergency if you’re using the appliance, because combustion gases including carbon monoxide can leak into living space through compromised mortar joints. We answer live 24 hours a day, 7 days a week, and we’ll prioritize Monrovia calls involving active safety hazards. If you smell smoke where you shouldn’t or your CO detector has triggered, exit the home and call us from outside.
Our pricing is consistent across the San Gabriel Valley - we don’t zone-rate. What can make a Monrovia job more involved is the age and condition of the housing stock: the concentration of unlined pre-war chimneys near Old Town often requires more masonry preparation before liner installation than a 1980s tract home in Arcadia. We price for the actual work, not the ZIP code, and our free estimate gives you the exact number before any work begins.
Every liner installation and rebuild is backed by our 90-Day Done Right Promise - in writing, no arguing. If it’s not right, we come back and make it right. Manufacturer warranties on HeatShield, Gelco, Olympia Chimney, and Famco materials apply additionally where applicable. We’ve been in business since 1984 and we plan to be here in thirty more years, so our guarantee means something. Call (844) 803-1545 with questions about coverage on your specific job.
We also handle Chimney Cleaning & Sweep in Monrovia and Chimney Repair in Monrovia - many of our liner customers first call us for an annual sweep and camera inspection that reveals the underlying issue. A clean flue with a documented condition report is the best foundation for deciding whether repair, relining, or rebuild is the right path.
