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, CA is the service we get called for most often, and for good reason – the city’s 1980s and 1990s tract homes are full of direct-vent gas fireplaces and factory-built wood-burning inserts that were installed cheaply and are now hitting the age where chase covers rust, flashings separate from Spanish-tile roofs, and flue liners crack from years of hot, dry summers followed by winter firing cycles. Walnut Chimney has served Walnut since 2017, and we bring the right professional-grade materials – DuraFlex, HeatShield, Copperfield, and Gelco – to every job, from a simple cap replacement to a full liner repair. Call (855) 341-3461 for a free estimate.
Why Walnut Homes Are Different
Walnut sits in the eastern San Gabriel Valley, where hot, dry summers and mild winters mean most fireplaces only get used between Thanksgiving and Valentine’s Day. That pattern creates a specific problem: creosote buildup is slow, but dust, ash, spider webs, and rodent or bird debris accumulate year-round in flues that sit idle for nine months at a time. When you light that first fire in November, that debris burns off as smoke, and any blockage in the flue means it comes back into the living room.
The housing stock makes the repair side more complicated, too. Most Walnut homes are Mediterranean or Spanish-style stucco tract houses with tile roofs and exterior chase enclosures – the framed, stuccoed boxes that hide the flue pipe on the outside wall. Those chases collect eucalyptus leaves and debris along the hillside edges near the 60 Freeway corridor, and the dry-wood-termite pressure in this part of the Valley means wood-framed chases need regular inspection. The Spanish-tile roofs common on 1990s homes also make chimney cap access trickier than on the flat-tile homes you see in neighboring cities, so we plan our roof access around that from the start. Add in the city’s ongoing infill and room-addition work, and we regularly find post-construction dust and stucco residue inside flues that were never sealed off during remodeling.
Styles & brands we work with
Our Main Walnut Services
Walnut homeowners call us for two core services – chimney sweeping and dryer vent cleaning – and we handle both on the same visit more often than not.
Chimney Sweep in Walnut
A proper sweep in Walnut means more than brushing the flue from the firebox up. We remove accumulated ash and debris, inspect the liner from top to bottom, and check the cap, crown, and chase cover for damage at the same time. In a Walnut tract home built in the 1990s, that inspection matters because factory-built fireplace components wear on a 20-to-30-year schedule, and many are due. Post-construction dust and stucco residue from room additions also end up in flues, which means a visual check before the first burn of the season is the cheapest insurance you can buy. See Chimney Sweep in Walnut for details.
Dryer Vent Cleaning in Walnut
Dryer vent cleaning is a fire-safety service, not an add-on. The NFPA lists dryers as a leading cause of home fires, and in a warm, dry climate like Walnut’s, lint dries out fast and becomes kindling. We run brushes and an inspection camera through the full vent run from the dryer to the exterior termination, removing compacted lint, bird nests, and anything else that restricts airflow. Homes with side-wall vent terminations along hillside lots get extra attention in fall, when Santa Ana winds drive leaves and ash directly into those openings.

Chimney Repair in Walnut
Chimney repair in Walnut is the service that separates full-stack specialists from sweep-only companies. We repair what we find, using the right brand for the job – this is where our material selection actually matters. A chimney cap that rusted through in a 1990s chase enclosure gets replaced with a Copperfield or Gelco cap sized for the flue, a cracked flue liner gets handled with a DuraFlex stainless liner, and damaged flue interiors get resurfaced with HeatShield ceramic. When a Santa Ana event blows eucalyptus leaves and ash into side-wall vent terminations along the hillside edges near the 60 Freeway corridor, the damage is usually to caps, flashings, and chases – all repair work we handle directly. For a full breakdown of repair services, see Chimney Repair.
Chimney Cap Installation
Signs you need it
You can hear or see birds entering the flue, or you find rust flakes and water staining on the chase exterior.
What it costs in Walnut
Chimney cap installation in Walnut typically runs $350 to $650, depending on flue size and cap type.
How we do it
We measure the flue opening, select a Copperfield or Gelco cap sized correctly for the flue, mount and secure it, and confirm it seats flush before checking the chimney’s general condition.
Chimney Cap Replacement
Signs you need it
Your existing cap is rusted through, dented, or missing sections, or the screen mesh has torn and birds have already tried nesting.
What it costs in Walnut
Chimney cap replacement in Walnut typically costs $250 to $450, including removal of the old cap and disposal.
How we do it
We remove the damaged cap, inspect the flue opening and crown, install the new cap with corrosion-resistant hardware, and test that it sits level and sealed.
Chimney Liner Installation
Signs you need it
You see flaking tile pieces in the firebox, smell smoke when a fire is not lit, or a previous inspection showed cracked or missing liner sections.
What it costs in Walnut
Chimney liner installation in Walnut typically runs $2,500 to $5,000, depending on flue length and whether we need scaffolding for the tile roof.
How we do it
We measure the full flue run, pull the old liner if present, install a DuraFlex stainless liner sized for the appliance, insulate and seal it, and test the draft before we leave.
Chimney Flashing Repair
Signs you need it
You see water staining on the ceiling near the chimney, damp drywall in the chase, or rusted metal where the chimney meets the roof.
What it costs in Walnut
Chimney flashing repair in Walnut typically costs $450 to $900, more if we need custom bending or tile roof access equipment.
How we do it
We inspect the existing flashing, remove the failed section, cut and bend replacement flashing to the chimney’s profile, then seal and test it with water before cleaning up.
Chimney Crown Repair
Signs you need it
You see cracks or spalling concrete on the chimney crown, or water is leaking down the flue after rain.
What it costs in Walnut
Chimney crown repair in Walnut typically runs $550 to $1,050, depending on crown size and whether resurfacing or full replacement is needed.
How we do it
We assess the crown’s condition, remove loose material, rebuild or resurface it with the right mix for the climate, and re-seal the top so water sheds off correctly.

| Chimney cap installation | $350 – $650 |

How often should a chimney be repaired in Walnut?
Have your chimney inspected every year, and plan for cap, flashing, or crown repairs as soon as visible rust, cracking, or leaks show. Walnut’s dry climate slows rust but does not stop it, and neglected water entry becomes expensive quickly.
Do I need a repair before the next burn season?
If water has been entering the flue, settle the repair before you light another fire. Moisture inside a flue liner weakens it, and the heat of the next fire can accelerate cracking. Call (855) 341-3461 for a free estimate.
