Chimney sweep logs do not sweep chimneys. They loosen some creosote - which then falls where a brush and vacuum still have to collect it.

Why Pilgrim Chimney Is Walnut’s Preferred Chimney Sweep Company
Len Pacheco built Pilgrim Chimney around a simple idea: homeowners deserve a chimney contractor who can actually fix what the inspection finds, not just hand over a report and a referral. In Walnut, that matters because so many of the chimneys we open up are original to homes built in the 1970s and 1980s, and they carry the wear you would expect from four decades of dry summers and nesting birds.
Our customers in Walnut tend to be diligent about annual maintenance. The fireplaces here are used lightly, which means creosote stays in the first-degree range almost always. What owners actually need is someone they trust enough to say, “Your flue is fine, here is the photo,” instead of inventing a third-degree emergency. We show every customer their camera footage after a sweep. If there is nothing wrong, we tell you, and the report says so. That steadiness is why the bulk of our Walnut work comes from repeat customers and direct referrals between neighbors.
Response time to Walnut from our Victorville base is dependable. Most sweeps are booked within a week, and the seasonal crunch before the holidays fills faster. We service Walnut, Rowland Heights, West Covina, and Pomona on regular routes.

Chimney Sweep Services in Walnut
Chimney Sweep Services in Walnut center on inspection, light creosote removal, and firebox cleaning for fireplaces that see a handful of burns each winter. The local trade is not mostly heavy soot work. It is verifying that a factory-built unit from the Carter administration still vents safely, that the spark arrestor cap is intact, and that no bird or rodent made a home in the flue during the nine months the fireplace sat idle.
Level 1 and Level 2 Inspections
Most Walnut homeowners only need a Level 1 inspection with their annual sweep. If you have changed appliances since the last inspection, added a gas log set, or are buying a home, that is when a Level 2 makes sense. The camera goes into the flue either way, and you see the footage with us in real time.
Creosote and Soot Removal
In Walnut’s low-use fireplaces, first-degree creosote is the norm. It brushes out quickly with rotary loops. The honest answer we give most customers: your creosote is light, your flue is sound, and you are good for another year. Soot is similarly straightforward unless a gas log set has been running with an improper air-to-fuel mix, which leaves a fine black powder that needs a different cleaning approach.

Chimney Cleaning in Walnut
Chimney Cleaning in Walnut is a dust-controlled job from start to finish. We lay protective sheeting from the entry door to the hearth, run a HEPA-filtered vacuum throughout the sweep, and clean the firebox with brushes and a drop cloth. You will not find ash footprints on the carpet when we leave.
Annual Sweep and Fireplace Cleaning
An annual sweep in Walnut takes about an hour for a standard masonry or factory-built fireplace. The technician brushes the flue, vacuums the smoke shelf and damper assembly, removes debris from the firebox, and checks the cap. For gas-log fireplaces, we also clean the log set and verify the pilot and burner flame look right.
Bird and Debris Removal
The hillside lots in the 91789 tract and older streets near Lemon Creek Park see real bird pressure. Starlings and sparrows get under missing spark arrestor caps and build nests in the flue. We remove the nest, inspect for moisture damage, and recommend a Copperfield or Olympia cap replacement if the original is rusted through.
Trusted Brands We Service in Walnut
We work with professional-trade materials, not hardware-store patch kits. That means when a Walnut homeowner needs a new cap, damper, or liner repair, we have Gelco, Famco, and Copperfield components on the truck or sourced quickly from our distributor network. HeatShield resurfacing is a big part of our Walnut work too. A cracked clay-tile flue does not automatically mean a full liner replacement. We can often restore the flue in place, which keeps the firebox intact and preserves the look of the original fireplace. DuraFlex in Walnut liner systems go in when a full reline is actually warranted. We show the camera footage either way.

AfterCommon Chimney Sweep Problems We See in Walnut Homes
- Rusted or missing spark arrestor caps on 1970s – 1980s factory-built chimneys. Decades of dry heat and nesting birds take these out. A missing cap is an open invitation and the single most common problem we fix in Walnut.
- Gas inserts vented into flues never designed for them. A homeowner adds a gas log set for convenience, but the original clay-tile flue was sized for a wood fire. The camera shows the gap in draft and the risk.
- First-degree creosote presented as a scary third-degree problem. This is the classic upsell. Walnut fireplaces burn so infrequently that light creosote is normal. We show the footage instead of selling a chemical treatment nobody needs.
- Bird nests and debris blocking the flue after a long idle season. When the fireplace goes unused from March to November, starlings can build a nest in days. A blocked flue is a carbon monoxide hazard, and it is easy to catch with an annual sweep.

FAQs About Chimney Sweep in Walnut
Yes, you need the inspection even in a low-use fireplace, because the risks in Walnut are not about creosote accumulation. They come from bird nests, missing spark arrestor caps, and flue damage you cannot see from the hearth. A yearly sweep catches those before they become a draft problem or a carbon monoxide risk. Call (866) 253-5031 and we can schedule your sweep during our next Walnut route.
Sometimes, and only after a camera inspection shows the flue is properly sized and lined for the insert you want. In Walnut’s 1970s and 1980s tract homes, the original flue was often sized for an open wood fire, not a sealed gas insert. Installing the insert without verifying the flue can create a draft mismatch and carbon monoxide risk. We show you the camera footage before recommending anything.
First-degree creosote is a light, flaky soot that brushes off easily. It is normal in Walnut where fireplaces burn only a few times a season. Third-degree creosote is a hard, glazed, tarry coating that requires chemical or mechanical removal, and it signals the chimney has been burning green wood or at low temperatures for a long time. In Walnut, you rarely see third-degree anywhere. If someone tells you the chimney needs a $500 chemical treatment after one camera pass, ask to see the footage yourself. Call us at (866) 253-5031 for a straight answer.
Every Pilgrim Chimney sweep in Walnut runs dust-controlled. We lay drop cloths from the door to the hearth, use a HEPA vacuum through the entire job, and brush the flue with the damper sealed so the dust goes up, not out. Our techs take their shoes off or wear boot covers inside. The hearth and the living room floor look the same when we leave as when we arrived.
Yes. Birds hanging around the chimney cap usually mean the spark arrestor is missing, rusted, or damaged, and they are either nesting or thinking about it. In Walnut’s hillside-adjacent tracts, we routinely pull starling and sparrow nests out of flues and find eggs in them. A cap replacement with a Copperfield or Olympia unit solves it. We can inspect yours on the next Walnut route. Call (866) 253-5031 and mention the birds.
On a recent job in the 91789 tract near the Puente Hills, our tech found a 1980s Heatilator with a rusted-out spark arrestor cap and a cracked clay-tile flue liner. The homeowner had just installed a new gas log set, but the flue was never rated for it. Our camera showed the gap, and we recommended a HeatShield liner repair rather than a full rebuild. The repair kept the original firebox and saved the homeowner from an unnecessary tear-out.
If your Walnut chimney has not been looked at this year, or if you are wondering whether that gas insert is venting correctly, call (866) 253-5031. We schedule sweeps and inspections throughout Walnut’s 91788, 91789, and 91795 zip codes, and every estimate is free.
