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 comes down to two things: cracked crowns from decades of sun exposure, and flashing failures where clay-tile roofs meet the flue. The hillside estates and 1980s – 2000s Mediterranean-style homes here were built with substantial masonry fireplaces, many of which are now 20 to 40 years old. That’s exactly the age where mortar joints start spalling and spark arrestors rust through. Sherwood Chimney Sweep has served Walnut since 2017, and we approach every job as a full-system inspection, not just a patch. Call (833) 589-8498 for an honest assessment.
Why Walnut Homes Are Different
Walnut’s housing stock is distinctive: large Spanish and Mediterranean-style single-family homes with stucco exteriors, clay-tile roofs, and fireplaces built as architectural centerpieces. Many sit on hillside lots in neighborhoods like Snow Creek and Three Oaks, where the elevation exposes chimneys to more direct sun and stronger Santa Ana winds than you’d see in the flat parts of the San Gabriel Valley.
The hot, dry summers and intermittent winter cold snaps create a specific maintenance pattern. Fireplaces here often get used only a handful of times each season, so creosote accumulates slowly. But the dry canyon winds push debris, leaves, and bird nesting material into uncapped flues year-round. Spark arrestor screens are not optional in Walnut; they’re the difference between a contained firebox and an ember landing on a tile roof during a red-flag wind event.
We also see a lot of decorative outdoor fireplaces and built-in BBQ chimneys that have never been cleaned since the home was built. Homeowners assume outdoor chimneys need less care. They don’t. The same wind, debris, and seismic settling apply, and we’ve found cracked firebox brick and deteriorated mortar in outdoor structures that look pristine from the patio.
Styles & brands we work with
Our Main Walnut Services
Two calls we take most often from Walnut homeowners are chimney sweeping and dryer vent cleaning. Both are fire-prevention work, and both are services we handle as one contractor rather than sending you to find a second specialist.
Chimney Sweep in Walnut
A Chimney Sweep in Walnut means more than removing soot. On hillside homes with tall flues and clay-tile roofs, it means checking the spark arrestor, the crown, the flashing, and the firebox in one visit. We sweep, then inspect, then document what we found. For homes that only burn a few fires each winter, an annual sweep before the first cold snap is the right cadence. Walnut’s wind-driven debris makes it a safety inspection as much as a cleaning.
Dryer Vent Cleaning in Walnut
Dryer Vent Cleaning in Walnut addresses the leading cause of household dryer fires: lint accumulation in the vent run. In two-story Walnut homes, dryer vents often run long distances through walls or up through the roof, which means more surface area for lint to collect. We clean the full run, inspect the termination point, and confirm the vent is moving air at the right velocity. It’s fire prevention, not just cleaning.

Chimney Repair in Walnut
Chimney repair in Walnut is a masonry and flashing problem more often than a liner problem. The stucco and clay-tile construction that defines this city’s homes means chimneys sit exposed to intense sun, dry wind, and the occasional seismic shift. Crowns crack, mortar joints erode, and flashing pulls away from the roofline. Left alone, water gets into the chase, and that’s when repair turns into rebuild. Chimney Repair is the core of what we do, and we diagnose every issue with camera evidence before recommending anything.
Chimney Cap Installation
Signs you need it
You have no cap, or you hear birds and see nesting material falling into the firebox.
What it costs in Walnut
Chimney cap installation in Walnut typically runs $250 – $550 depending on flue size and roof access.
How we do it
We measure the flue, install a stainless cap with a built-in spark arrestor, and secure it with mechanical fasteners rated for Santa Ana winds.
Chimney Crown Repair
Signs you need it
You see hairline cracks across the top of the chimney, or water staining on the ceiling near the flue.
What it costs in Walnut
Chimney crown repair in Walnut runs $400 – $950, less if caught before the crack widens and water reaches the flue liner.
How we do it
We grind out the damaged surface, re-form the crown with a slight slope for runoff, and seal it with a weatherproof compound.
Chimney Flashing Repair
Signs you need it
Water stains on the ceiling near the fireplace, or visible gaps where the chimney meets the tile roof.
What it costs in Walnut
Flashing repair in Walnut ranges $350 – $850, with clay-tile roof access adding time on hillside lots.
How we do it
We remove the old flashing, install new step and counter flashing, and seal the transition so water sheds away from the flue.

Do I need a chimney liner if my fireplace drafts fine?
Not necessarily. A camera inspection is the only way to know. We never recommend a liner unless the footage shows cracks, gaps, or deterioration. Call (833) 589-8498 for a straight answer, not a sales pitch.
Can you repair my chimney from the roof without damaging my clay tiles?
Yes. We use roof-access methods specifically for clay-tile roofs common in Walnut’s hillside homes. We protect the tile line and install flashing that matches the existing roofline. Free estimates at (833) 589-8498.
