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: a stucco-clad chimney chase that’s cracked after decades of inland sun, or a flue that’s been sitting unused long enough for pests and debris to take over. Most Walnut chimneys belong to Mediterranean and Spanish-tile homes built between the 1970s and 1990s, and plenty of them still have the original damper, cap, and flue liner from construction day. We carry the materials to fix what we find on the first visit, not just hand you a report and a recommendation. Call (855) 341-5439 to talk through what’s going on.
Why Walnut Homes Are Different
Walnut sits in the hills at the southern edge of the San Gabriel Valley, and that geography shapes every chimney we open. The summers are hot and dry, with Santa Ana wind events that push leaf litter, dust, and pollen straight into uncapped or poorly capped flues. Winters are mild enough that a lot of homeowners light maybe five to ten fires a season, sometimes fewer. That means the chimney spends most of the year closed up, which sounds fine until you realize what’s been moving in while nobody was looking.
The recurring find in Walnut is the long-idle flue. A chimney that never sees a fire still collects debris, and in hillside neighborhoods that back onto the south hills brush, it collects more than dust. We regularly pull dried leaves, pine needles, and bird or squirrel nesting material from flues homeowners assumed were sealed. Add stucco exteriors that crack slowly through decades of heat expansion, and a lot of Walnut chimneys show their first real problems when someone finally lights a fire and the house fills with smoke or the damper won’t budge. The work here is less about heavy soot accumulation and more about correcting deferred wear.
Styles & brands we work with
Our Main Walnut Services
Most Walnut homeowners call us for one of two things: the routine chimney cleaning that hasn’t happened in years, or the dryer vent concern an inspector or appliance tech flagged. Both are fire-safety visits at their core.
Chimney Sweep in Walnut
In Walnut, a chimney sweep appointment usually starts with us removing what’s collected during months of disuse rather than scrubbing off creosote from heavy burning. That changes the job: we’re checking for pest intrusion, blockages, cracked flue tiles, and a damper that’s seized from sitting. You can read more about how sweeping works in Walnut specifically, including what we check on the rare low-use fireplace, on our dedicated Chimney Sweep in Walnut page.
Dryer Vent Cleaning in Walnut
Dryer vents in Walnut’s larger 1970s-to-1990s homes often run long horizontal distances from the laundry room to an exterior wall, sometimes through attic space or along exterior stucco walls. Lint builds up in those long runs faster than homeowners expect, and a constricted vent forces the dryer to work harder while pushing flammable material toward the exhaust point. If an inspector or appliance tech has flagged it, the fix is straightforward. See our Dryer Vent Cleaning in Walnut page for what’s involved.

Chimney Repair in Walnut
Chimney repair in Walnut is rarely a single-item job. The typical call starts with a visible crack in the stucco chase or a leak around the flashing, and by the time we open it up, the crown has hairline fractures and the damper has rusted from years of trapped moisture. Because so many Walnut chimneys date to original construction and have never been serviced, the repair is usually about restoring several connected components at once. Limestone Chimney Sweep has served Walnut since 2014, and our Chimney Repair work is built around carrying professional-grade parts so we can fix what the inspection turns up on the spot.
Chimney Cap Installation
Signs you need it
You hear animals in the flue, find nesting material in the firebox, or notice water staining on the ceiling near the chase after rain.
What it costs in Walnut
A typical chimney cap installation in Walnut runs $300 – $600 depending on flue size and cap style.
How we do it
We measure the flue opening, mount a stainless or copper cap sized to the existing chase, and secure it with a mechanical fastening system so Santa Ana winds don’t work it loose.
Chimney Liner Installation
Signs you need it
You see cracked or spalling flue tiles during an inspection, notice white staining on the exterior brick, or a sweep flags gaps in the existing liner.
What it costs in Walnut
Liner installation in Walnut generally runs between $1,500 and $4,000 depending on flue length, diameter, and accessibility through the chase.
How we do it
We spec the correct diameter for your appliance, lower a DuraFlex or HeatShield liner down the existing flue, secure it at the top plate, and reconnect the appliance with a properly sized connector.
Chimney Flashing Repair
Signs you need it
Water runs down the chimney chase into the attic after rain, or you see rusted, lifted, or missing flashing at the roofline.
What it costs in Walnut
Flashing repair around a Walnut chimney typically lands between $350 and $800 depending on how many planes the chimney intersects.
How we do it
We remove the old flashing, cut and fit new step and counter flashing into the existing roofline, and seal the transition with a durable exterior sealant rated for inland sun exposure.
Chimney Crown Repair
Signs you need it
The concrete crown has visible cracks or is crumbling at the edges, or water is wicking into the top courses of the chase.
What it costs in Walnut
Crown repair or replacement in Walnut usually runs $400 – $1,000 depending on crown size and whether we’re resurfacing or rebuilding.
How we do it
We grind out failed sections, build a proper overhang with a scored expansion joint where needed, and finish with a weather-sealed surface that sheds water instead of absorbing it.
What Chimney Repair Costs in Walnut
| Item | Typical range in Walnut |
|---|---|
| Chimney cap installation | $300 – $600 |
| Chimney flashing repair | $350 – $800 |
| Chimney crown repair | $400 – $1,000 |
| Chimney liner installation | $1,500 – $4,000 |
Do I really need a new liner, or can the old one be cleaned?
If the existing flue tiles are cracked or missing, cleaning will not restore the liner’s ability to contain heat and gas. We only recommend replacement when we can show you the damage on camera. Call (855) 341-5439 for an exact quote and we’ll review the photos with you.
Can a cracked chimney crown stay as-is for a season?
A cracked crown keeps letting water into the chase, and one heavy winter rain can push moisture behind the stucco. If it’s a hairline crack, a resurfacing coat may hold for a while. Call (855) 341-5439 for an assessment.
Brands We Service in Walnut
We stock and install parts from DuraFlex, HeatShield, and Olympia Chimney, which means a repair in Walnut doesn’t wait on a hardware-store special order. When we find a failed liner section or a corroded cap, we typically have the replacement on the truck. See our brands for the full range.

In Walnut, the two things that push price up are access and age. A chase that’s partly enclosed in stucco or a flue with a sharp offset near the smoke shelf takes longer to work through, and original 1970s dampers often fight you on the way out. Every quote is a flat price agreed before we start, so the number we give you is the number you pay.

"Drop cloths everywhere, HEPA vac, and not a speck of soot on the carpet. I'd been dreading the mess for nothing."
— Bethany Pruitt"Fireplace had never drawn properly since we moved in. He found the damper was only opening halfway due to a bent linkage and fixed it in ten minutes."
— Neil Hayes"Swept it, capped it, and installed a proper damper. The downdraft smell in the summer that we'd lived with for years is gone."
