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: water getting into a 1970s-to-1990s masonry flue, or a spark arrestor and cap that were never built for the work they do on a two-story foothill home. We work on both, plus the tall multi-flue systems you see in the gated communities and hillside estates where standard ladders simply don’t reach. Walnut’s dry climate slows creosote buildup, but it doesn’t stop crown cracks, rusted caps, or flashing failures. If you’re seeing water stains near the fireplace or hearing birds inside your flue, call Santa Ana Chimney Sweep at (855) 341-9658. We’ve served Walnut since 2016.
Why Walnut Homes Are Different
Most of Walnut’s housing stock was built between the 1970s and the 1990s, and much of it sits on sloping lots that push chimneys well above roofline. That’s a different animal from the single-story flues common in Pomona or West Covina. A two-story masonry chimney on a hillside in the 91789 ZIP might stand 35 feet tall, with a decorative shroud and spark arrestor that were installed when the home was built. Those components are exposed to more wind, more direct sun, and more rain than shorter systems. The Santa Ana wind events that sweep through the foothills can carry ash and fine soot into open flues, and when a chimney sits unused for six or eight months, those deposits settle into the mortar joints and behind the damper. HOA communities around the Three Oaks, Snow Creek, and Ridgeline areas sometimes require a written inspection report before any cleaning or repair work happens. We’re used to producing that paper, and we photograph everything so the HOA board sees exactly what we saw.
Styles & brands we work with
Our Main Walnut Services
Most Walnut homeowners call us first about one of two things: a fireplace that hasn’t been cleaned in years, or a dryer vent that’s been pushed to the back of the to-do list. Both are fire-safety work, and both are handled by the same crew.
Chimney Sweep in Walnut
Chimney sweeping in Walnut is more than running a brush up a flue. The tall masonry systems in this city need staged ladders or a roof-access plan, and many have glazed creosote that’s hardened into a tar-like layer from years of low-use, high-moisture cycles. We sweep the full system, from firebox to crown, remove the debris, and inspect the liner while we’re in there. For the full scope on sweeping, see our Chimney Sweep in Walnut page.
Dryer Vent Cleaning in Walnut
Dryer vents are one of the leading causes of house fires in the US, and in a city with as many two-story homes as Walnut, long vertical vent runs are the norm. Lint builds up inside the duct, the airflow drops, and the dryer has to work harder. We clean the entire run, reattach loose joints, and tell you if the vent needs a mesh guard. Learn more on our Dryer Vent Cleaning in Walnut page.

Chimney Repair in Walnut
Chimney repair in Walnut is most often about water and rust. Homes built in the 1970s through the 1990s have masonry crowns that crack under decades of sun exposure, and the thin metal caps installed during original construction corrode and let rain straight down the flue. When a fireplace then sits unused through Walnut’s long dry season, soaked mortar joints dry and spall, and the damage compounds. Our team handles the full repair scope, from cap replacement to flue relining, and we specify materials by name. For a broader look at how we approach this work, see our Chimney Repair service hub.
Chimney Cap Installation
Signs you need it
You have an open or uncapped flue, birds nesting inside, or rain water pooling in the firebox after storms.
What it costs in Walnut
Chimney cap installation in Walnut typically runs $280 – $520, depending on flue size and roof access.
How we do it
We measure the flue opening, install a stainless steel or copper cap with the correct screen size for Walnut’s bird pressure, and secure it to the crown with mechanical fasteners.
Chimney Cap Replacement
Signs you need it
The existing cap is rusted through, has detached from the crown, or the spark arrestor mesh has holes large enough for embers to escape.
What it costs in Walnut
Replacement typically runs $320 – $580 in Walnut, including removal of the old cap and haul-away.
How we do it
We pull the old cap, inspect the crown beneath it, and install a new cap rated for the wind exposure common on Walnut’s foothill roofs.
Chimney Liner Installation
Signs you need it
Your existing clay tile liner is cracked, spalling, or missing sections, or you see flue gases staining the chimney exterior.
What it costs in Walnut
Chimney liner installation in Walnut runs $2,400 – $4,800, depending on flue height and whether it’s a standard or irregular masonry passage.
How we do it
We size a DuraFlex flexible stainless liner to the exact flue dimensions, drop it from the top, insulate if the local code requires it, and reconnect the appliance at the base.
What Chimney Repair Costs in Walnut
| Item | Typical range in Walnut |
|---|---|
| Chimney cap installation | $280 – $520 |
| Chimney cap replacement | $320 – $580 |
| Chimney liner installation | $2,400 – $4,800 |
Do I need a new liner or can it be repaired?
Most cracked clay liners can’t be patched reliably. If the damage is limited to the top few feet, a section replacement or HeatShield resurfacing may work. We’ll show you the camera footage and give you both options if they exist.
Why does my chimney leak in Walnut even though it barely rains?
The damage usually happened months earlier. A cracked crown or failed flashing lets water in slowly, and Walnut’s long dry spells hide the problem until the next rain. Repoint and recrown before the winter cycle.
Brands We Service in Walnut
We install and service materials from Olympia Chimney, Famco, Copperfield, and DuraFlex. That means caps, liners, and chase covers are ordered in the right size instead of adapted from whatever’s on the truck. Parts stocked locally in Walnut keep most cap and crown jobs to a single visit. See our brands for the full roster.

Whatever the price, it’s agreed before the work starts, and you’ll see the problem on camera before we spend a dime on materials.
