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 dealing with a flue that has been in place since the house was built in the 1970s, 1980s, or 1990s. The mix of concrete tile roofs, stucco fireboxes, and decorative mesquite-burning hearths creates creosote patterns and wildlife intrusion problems that a newer home rarely sees. We inspect first, show you the camera footage, and quote only what the flue actually needs. Call (833) 362-8107. We answer 24/7. Fast dispatch from 7am to 7pm, Sunday through Friday.
Why Walnut Homes Are Different
Walnut’s housing stock is dominated by planned subdivisions built from the late 1960s through the 1990s. Most of these are Mediterranean and Spanish Revival two-story homes with stucco exteriors, concrete tile roofs, and original masonry or metal fireplaces and flues. A chimney built in 1978 on a hillside-adjacent tract near the 60 Freeway has very different wear patterns than one built in 1992 on a flat interior lot. We see cracked mortar crowns, missing spark arrestors, and flue tiles that shifted during the original settling of the foundation.
The climate plays a role too. Walnut’s hot, dry summers bake creosote into a hard, glassy glaze that a brush alone will not remove. Fireplaces sit idle for months, then get used heavily during Santa Ana wind events and the holiday season. Birds and squirrels move into uncapped flues during the long off-season, and the first fire of the year pushes smoke back into the living room when the nest blocks the draft. That is the moment most Walnut homeowners call us.
Another local reality: many of these chimneys have never been professionally swept. They were built with the house, used casually for decades, and passed to a second or third owner who assumes everything is fine. Inspection-first service is the norm here because most Walnut homeowners do not know what is actually inside their flue until a camera shows them.

Our Main Walnut Services
Walnut homeowners call us most about two things: cleaning the chimney before burning season and clearing the dryer vent that has not been touched since move-in. Both are fire-risk items, and both are services we handle with the same diagnostic approach.
Chimney Sweep in Walnut
A Chimney Sweep in Walnut involves removing creosote from the flue, smoke chamber, and firebox. In Walnut’s Spanish-style two-story homes, that often means working around tile roof details and reaching a chimney cap that has rusted in place. We sweep before the Santa Ana winds arrive because that is when most families light the first fire. We also check for bird nests, cracked flue tiles, and draft problems while we are up there, so you get an inspection with every sweep, not just a brush through the flue.
Dryer Vent Cleaning in Walnut
Dryer Vent Cleaning in Walnut clears the lint that builds up inside a dryer exhaust run. In Walnut’s two-story homes, dryer vents often route through a wall and up to the roof, which means longer runs, more elbows, and more places for lint to collect. A clogged vent makes the dryer run hotter and longer, and lint is the same kind of fire hazard as creosote. We clean the full run from the dryer to the exterior termination and show you the before and after with a camera.
Chimney Repair in Walnut
Chimney repair in Walnut usually starts with a cracked flue tile or a failed mortar crown on a home built between the late 1960s and the 1990s. The combination of hot, dry summers and the sudden heat of a Santa Ana-season fire puts stress on original clay flue liners, and many have cracked without the homeowner ever knowing. We diagnose before we quote, using a camera inspection so you see exactly what we see. Our Chimney Repair work uses contractor-grade materials like HeatShield and DuraFlex, which means we can often restore a damaged liner rather than demolish the chimney to replace it.
Chimney Cap Installation
Signs you need it
Birds nesting in the flue, water staining near the firebox, or a rusty, missing cap at the roof line are the usual signs in Walnut.
What it costs in Walnut
Chimney cap installation in Walnut typically runs $180 to $340 for a standard galvanized or stainless cap on a masonry flue.
How we do it
We measure the flue opening, set a properly sized cap, and secure it to the crown so squirrels and rain cannot work their way in.
Chimney Liner Installation
Signs you need it
Cracked flue tiles seen on a camera inspection, smoke backing into the house, or a chimney that will not draft properly are signs a liner has failed.
What it costs in Walnut
Chimney liner installation in Walnut typically runs $900 to $2,200 depending on the flue height and whether the existing liner must be removed first.
How we do it
We size the liner to the appliance, run the new DuraFlex liner down the existing flue, and insulate around it so the chimney drafts correctly.
What Chimney Repair Costs in Walnut
| Item | Typical range in Walnut |
|---|---|
| Chimney cap installation | $180 – $340 |
| Chimney liner installation | $900 – $2,200 |
| Chimney crown repair | $350 – $800 |
Can you repair a cracked flue without tearing out the chimney?
Often, yes. HeatShield resurfacing restores a cracked clay liner from the inside without demolition, and it comes with documented performance data. We use it whenever the damage allows, because restore before you replace usually saves thousands.
What does a chimney flashing repair involve in Walnut?
Flashing repair means sealing the joint where the chimney meets the concrete tile roof. In Walnut’s Mediterranean-style homes, this joint shifts over time and leaks into the attic, so we remove old sealant, reset the flashing, and re-seal it with contractor-grade materials. Call (833) 362-8107 for an exact quote.
Brands We Service in Walnut
We work with Copperfield, DuraFlex, and HeatShield products on Walnut chimneys. We keep common cap and liner components on the truck, which means many repairs are done in one visit. See our brands for the full list of what we install.

What pushes a Walnut price toward the higher end is usually access: a steep tile roof near the 60 Freeway, a two-story flue, or a liner that has collapsed and must be removed before the new one goes in. The written estimate sets the final price before any work starts, and the estimate itself is free.

FAQs About Chimney Company in Walnut
Some Walnut subdivisions have HOAs that review exterior work, especially anything visible from the street like a chimney cap. Check your HOA documents first. We can match existing roof details and use standard materials that most associations accept without issue.
Once a year if you burn wood regularly, and ideally before the Santa Ana wind season starts. Walnut’s dry summers bake creosote hard, so an annual sweep keeps the flue from glazing over. If you burn mesquite or manufactured logs, you may need it twice a year.

What Walnut Customers Say
"Swept it, capped it, and installed a proper damper. The downdraft smell in the summer that we'd lived with for years is gone."
- Rafael Torres"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."
- Sofia Garcia"Level two inspection before we bought the house. The report was detailed enough to use as a negotiating point and he explained every photo in it."
