Chimney sweep logs do not sweep chimneys. They loosen some creosote - which then falls where a brush and vacuum still have to collect it.
Chimney Company in Walnut, CA
Chimney repair in Walnut usually means one of two things: wildlife has gotten into a rarely-used prefab flue, or a decade-old chase cover has quietly rusted through. Lantern Chimney Sweep handles both, along with full chimney sweeping and dryer vent cleaning, for homes across the 91788, 91789, and 91795 ZIP codes. If you’ve spotted rust streaks on a stucco chase, heard scratching inside the firebox, or just bought a Walnut home and want a straight answer on what the flue actually needs, call (855) 341-8132 and we’ll take a look.
Why Walnut Homes Are Different
Walnut is a San Gabriel Valley hillside suburb where most single-family homes were built between the 1980s and 2000s as master-planned tracts. The Timberline, Snow Creek, and Walnut Valley developments set the pattern: Mediterranean and Spanish-style two-story homes with stucco walls, tile roofs, and factory-built prefab fireplaces with metal flues rather than masonary chimneys. That last detail drives almost everything we see on the job.
Prefab fireplaces mean lightweight metal flues, chase covers, and caps that age faster than brick. The local climate makes it worse. Walnut’s dry, warm inland weather means most fireplaces burn only a few times a year during short winter cold snaps. A rarely-used flue is an invitation. Scrub-jays, sparrows, and roof rats from the adjacent foothills and open brush routinely colonize uncapped chimneys, build nests against the flue liner, and sometimes die inside. The dry heat and Santa Ana wind events turn that nesting material into a fire hazard no one notices until it’s pointed out.
HOA rules in many Walnut tracts also push chimney work in a specific direction. Cosmetic concerns, rusted caps, visible staining on the chase, come up in resale inspections and HOA reviews. Homeowners here often call us for what’s essentially an inspection-and-compliance visit for a fireplace no one uses. The job is less about heavy creosote and more about making sure an unused flue is capped, intact, and safe.
Styles & brands we work with
Our Main Walnut Services
Two services dominate the calls we get from Walnut homeowners. Each has its own dedicated page with full detail, but here’s the quick version.
Chimney Sweep in Walnut
Most Walnut chimney sweeps are really wildlife removal plus flue clearing, not the heavy creosote work you’d see in mountain towns. We brush out the flue, document what we found, and tell you plainly whether the fireplace is safe to use. A Chimney Sweep in Walnut visit usually includes a chase-cover inspection and a cap check, because nesting pressure here runs year-round and an uncapped flue will be recolonized every spring. If you haven’t had the chimney looked at since buying the house, start here.
Dryer Vent Cleaning in Walnut
Walnut’s dry climate and two-story floorplans create a specific dryer vent problem: longer vertical runs through warm attics, where lint dries fast and sticks. A clogged dryer vent is a leading residential fire hazard, and pairing it with a chimney visit means one appointment settles two combustion-safety concerns. Details on Dryer Vent Cleaning in Walnut cover what we check, typical build-up in Walnut homes, and when to schedule.

Chimney Repair in Walnut
Chimney repair in Walnut tends to focus on the metal parts that fail in a dry climate: chase covers rusting through, caps missing, flashing pulling away from tile-roof transitions, and prefab liners that have corroded after years of disuse. Because most Walnut fireplaces see sparse use, damage usually accumulates silently. The homeowner finds out during a resale inspection, after a rain stain appears on the ceiling, or when a bird ends up in the firebox. We diagnose with a camera, show you what we found, and handle the fix ourselves. Our full Chimney Repair capability covers the range of issues we see from the Snow Creek tracts to the hillside streets backing onto open brush.
Chimney Cap Installation
Signs you need it
Birds, rats, or nesting material inside the firebox, or an existing cap that’s missing, rusted through, or blown off by Santa Ana winds.
What it costs in Walnut
Chimney cap installation in Walnut typically falls between $250 and $650 depending on flue size and whether a custom chase cover is required.
How we do it
We measure the flue opening, install a manufacturer-rated cap sized for the flue, secure it to the chase or crown, and verify the mesh spacing excludes Walnut’s common nesters.
Chimney Cap Replacement
Signs you need it
Visible rust, missing mesh, a cap that sits loose, or an older cap that no longer fits after wind or animal damage.
What it costs in Walnut
Replacement caps in Walnut run from $300 to $700 with the standard trade-grade components we use rather than hardware-store substitutes.
How we do it
We remove the failed cap, inspect the top of the flue for hidden damage, then install a new Gelco or Copperfield cap sized correctly for Walnut’s predominant prefab flues.
Chimney Liner Installation
Signs you need it
A liner that has separated at the seams, failed during an inspection, or shown corrosion on camera after years of sitting unused in a dry attic.
What it costs in Walnut
Full liner installation in Walnut runs between $2,500 and $5,000, while HeatShield resurfacing can restore eligible flues for $1,800 to $3,500.
How we do it
We size the flue, run a camera to confirm the damage, then either pull a DuraFlex liner system or apply HeatShield ceramic resurfacing when the existing liner can be saved.
Chimney Flashing Repair
Signs you need it
Water stains on the ceiling near the chimney chase, damp drywall, or visible gaps where the chase meets the tile roof during summer dry seasons.
What it costs in Walnut
Flashing repair in Walnut typically costs between $250 and $600 for a standard prefab chase and roof transition.
How we do it
We remove the failing flashing, inspect the underlayment, install new flashing sealed against Walnut’s tile roofs, and water-test the repair before we leave.
What Chimney Repair Costs in Walnut
| Item | Typical range in Walnut |
|---|---|
| Chimney cap installation | $250 – $650 |
| Chimney cap replacement | $300 – $700 |
| Chimney liner installation | $2,500 – $5,000 |
Walnut prices run higher than average when the home sits on a hillside lot with limited access, or when HOA requirements push the work toward specific cap styles and finishes. We give a flat price after the camera inspection, and we don’t recommend a liner, cap, or any repair unless the footage supports it.
How do I know if my Walnut chimney actually needs a new liner?
The camera footage tells you. We show you the separation, corrosion, or cracking as we record it. If the liner is intact but dirty, we say so, and a sweep is all you need. No liner gets recommended without visual evidence you’ve seen yourself.
Can you fix a chimney that animals have been nesting in?
Yes. We remove the nesting material, brush and sanitize the flue, inspect for damage, and install a cap sized to keep Walnut’s scrub-jays, sparrows, and roof rats out for good. Call (855) 341-8132 to schedule.
Brands We Service in Walnut
We work with professional-supply components from Famco, Copperfield, DuraFlex, and HeatShield. That means the cap, liner, or resurfacing material going into your Walnut home is the same spec a restoration contractor would order, not a box-store alternative. See our brands for the full list and what we stock locally for fast turnaround.

What pushes a Walnut quote upward: hillside access that makes setup slower, HOA-mandated cap styles, and the extra labor when a flue has been colonized multiple times. We quote a flat price before work starts, based on what the camera shows, so the number we agree on is the number you pay.

What Walnut Customers Say
"Thorough sweep and a clear report. He was running late from the job before and arrived near the end of the window, though he did call to warn me."
— Marisol Morales"Creosote buildup was worse than I realized. He measured it, showed me the glazing on the flue with the camera, and was honest that we were closer to a chimney fire than I wanted to hear."
— Oscar Torres"Swept it, capped it, and installed a proper damper. The downdraft smell in the summer that we'd lived with for years is gone."
— Roger Barrett
