Chimney sweep logs do not sweep chimneys. They loosen some creosote - which then falls where a brush and vacuum still have to collect it.
Fast, Reliable Chimney Sweep Across Walnut Creek
Chimney sweeping in Walnut Creek typically runs $189 to $329 for a standard fireplace cleaning, and most visits take 45 to 90 minutes. If you live in the 94595, 94596, 94597, or 94598 zip codes, our technicians know your streets, your housing stock, and the particular problems your chimney faces. Call (877) 752-4931 for a free estimate. Lenny Kendrick leads our team, and he has built our service around one principle: show up prepared to fix problems, not just document them.
Why Ambassador Chimney Sweep Is Walnut Creek’s Preferred Chimney Sweep Company
Walnut Creek homeowners call us because sweeps here aren’t just about creosote. We work across the mid-century ranches in the 94595 and 94596 flats, the newer stucco homes climbing the 94598 foothills, and the Rossmoor 55+ community where chimneys often sat untouched for decades. That range of housing stock means we see every firebox design, every liner material, and every failure mode Contra Costa County can produce.
Our Chimney Sweep team carries professional-grade inventory from HeatShield, Gelco, Olympia Chimney, and Famco. When a Walnut Creek inspection turns up a cracked flue tile or a rusted damper, we can usually fix it on the same visit instead of handing you a referral card. Lenny built the company this way deliberately: a homeowner should hear what’s wrong and what we can do about it in the same conversation. Reviews from Walnut Creek customers consistently point to the same thing: we tell you exactly what we find, with camera footage, and we don’t recommend work you don’t need.

Fireplace Cleaning in Walnut Creek
Fireplace Cleaning in Walnut Creek means more than running a brush up a flue. The mature oaks shading neighborhoods near the Iron Horse Trail and downtown mean acorn woodpeckers treat uncapped chimneys as granaries. Every fall, these birds drill hundreds of holes into caps and flue liners, and that damage sits hidden until the first cold snap. A proper cleaning here includes checking for that wildlife damage, removing hardened creosote, and telling you plainly whether the fireplace is safe to burn.
Creosote and Soot Removal
Walnut Creek’s hot, dry summers bake creosote into a hard glaze that a standard sweep won’t remove. Third-degree creosote requires mechanical removal or chemical treatment. We assess the degree of buildup during every visit and tell you which you’re dealing with.
Annual Maintenance for Occasional Burners
Plenty of Walnut Creek homeowners burn only a few fires per year. That creates a false sense of security. Even occasional burning deposits creosote, and idle months invite animals. We recommend an annual inspection regardless of how often you use the fireplace.
Chimney Services in Walnut Creek
Chimney Services in Walnut Creek extend well beyond cleaning. Our technicians perform Level 1 and Level 2 inspections, identify spalling fireboxes, replace rusted dampers, and install or repair caps. We also stock DuraFlex and Famco liner systems locally, so when a Rossmoor homeowner needs a reline before winter, we aren’t waiting on a supply house across the Bay.
Level 1 and Level 2 Inspections
A Level 1 inspection covers the readily accessible parts of the chimney. A Level 2 goes further, with camera equipment, and is what we recommend before any home purchase or after any weather event, animal intrusion, or chimney fire. In Walnut Creek’s older housing stock, Level 2 inspections routinely surface issues a visual check never would.

Chimney Cap Repair and Replacement
Woodpecker damage makes cap work a year-round necessity here. A missing or perforated cap lets rain, rats, and birds into the flue. We replace damaged caps with stainless steel models sized to your flue, not the adjustable hardware-store version that blows off in the first Delta wind.

Trusted Brands We Service in Walnut Creek
We stock parts from HeatShield, Gelco, Olympia Chimney, Famco, and DuraFlex. These are the lines commercial contractors spec, not what a big-box store keeps on a pegboard. For Walnut Creek customers, that means faster turnaround on liner work, cap replacement, and masonry repair. When a HeatShield kit can restore a flue instead of replacing it, we’ll tell you. When a DuraFlex liner is the better long-term answer, we’ll say that too. An honest recommendation, backed by parts we can install the same week, is the whole point.

AfterCommon Chimney Sweep Problems We See in Walnut Creek Homes
- Acorn woodpecker cap damage. The oak canopy along the Iron Horse Trail and near downtown gives these birds exactly what they need. They drill holes through caps and into flue liners every fall, and the damage often goes unnoticed until rain or smoke reveals it.
- Glazed creosote in rarely used fireplaces. Walnut Creek’s dry heat bakes creosote into a hard, shiny deposit that ordinary sweeping brushes won’t remove. We see this most often in Rossmoor homes where the fireplace has been decorative for years.
- Rusted dampers in mid-century ranches. Homes in the 94595 and 94596 flats built in the 1950s and 60s often still have their original dampers. Decades of Bay Area humidity and sporadic use leave them rusted open or seized shut.
- Animal nesting after idle summers. Roof rats and squirrels move into uncapped flues during the months when fireplaces sit unused. The first fire of winter either smokes the living room out or sends a rodent into the house.

FAQs About Chimney Sweep in Walnut Creek
Once a year, even if you never light a fire. Birds, rats, and rain don’t care how often you burn. An annual inspection catches woodpecker damage, cap failures, and water intrusion before they become structural problems. Call (877) 752-4931 to book one, and we’ll work around your schedule.
First-degree creosote is a dusty soot that brushes off easily. Third-degree is a hard, shiny glaze that forms when creosote bakes in high heat and low airflow. Walnut Creek’s dry summers accelerate the glazing process in flues that sit idle for months. Third-degree creosote is a serious fire hazard and requires mechanical removal. If you haven’t had your flue checked in a few years, call (877) 752-4931 and we’ll tell you exactly what’s in there.
Walnut Creek’s tree-protection rules keep mature oaks and dead snags standing, which gives acorn woodpeckers year-round habitat. Those birds store acorns by drilling holes into wood surfaces, and a chimney cap or flue liner is just another surface to them. Concord and Pleasanton don’t have the same density of protected oaks, so the damage pattern is far less common there. A stainless cap stops them. Call (877) 752-4931 if you hear tapping from your chimney in the fall.
Book a pre-departure inspection. We check the crown, flashing, cap, and damper, and we clear any animal nesting or debris. That way winter rain doesn’t enter through a crack nobody noticed while the house sat empty. Our Rossmoor scheduling is low-disruption: we can work while you pack, and you’ll get a camera report before you go. Call (877) 752-4931 to set it up.
For gas fireplaces, a sweep means cleaning the logs and burner, checking the venting, and verifying carbon monoxide isn’t leaking into the living space. We also inspect the flue for nesting or debris. In 55+ communities like Rossmoor, where residents are home all day, we pay extra attention to vent integrity and CO detection. Call (877) 752-4931 for a gas fireplace check.
