Level 1 sweep and inspection to the NFPA 211 annual standard - flue, crown, cap, and flashing checked and photographed
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 Redwood City
A chimney sweep in Redwood City typically costs $189 – $329 for a standard fireplace with a single flue, and most homes here are done in about an hour. If you live in Stambaugh Hurst, Redwood Village, or over in Emerald Hills, we already know the housing stock and the specific flue problems that come with it. Call (336) 863-3889 and you’ll get a live person, a written price before we start, and a technician whose name and photo you’ll see before they arrive.
Flatland tract homes and hillside custom builds fail in completely different ways here. Our Chimney Sweep team works both sides of Redwood City every week, and the difference matters when you’re deciding whether you need a basic sweep or a Level 2 inspection with a camera. We schedule directly with homeowners, not through a call center, and we’re usually in Redwood City neighborhoods within a few days of your call.
Why Alcott Chimney Sweep Is Redwood City’s Preferred Chimney Sweep Company
Alcott Chimney Sweep has been doing this since 2002, and in that time we’ve learned Redwood City’s split personality: the sunny flatlands where fireplaces sit idle for years, and the foggy western hills where masonry takes a beating from moisture. That local knowledge changes what we look for when we inspect your flue. A downtown ranch with an uncapped clay tile liner is a wildlife risk. An Emerald Hills brick chimney with spalling mortar is a water intrusion problem. Same service call, two very different checklists.
Every technician who comes to your Redwood City home has passed a background check and identity verification under the Threshold Standard. That’s not an add-on. You get the name and photo of the person coming to your door before the visit, and that person carries a photo ID badge you can check. For homeowners in Redwood City who are often alone during the day, have young children, or just want to know exactly who’s opening the gate, that protocol is the reason they call us back.
Our reputation in the Redwood City area is built on the 365-Day Done Right Promise. It means every repair we make carries a written guarantee, and if that repair fails within a year, the second visit is free. No fine print, no pro-rating, no arguing about what was covered. When you book a chimney sweep in Redwood City with us, you’ll know the exact price before work starts and you’ll have a year of accountability after it’s done.
Chimney Sweep Certified in Redwood City
Chimney Sweep Certified means our technicians in Redwood City are trained to remove creosote, soot, and animal debris from your flue, then verify the job with a visual check of the firebox, damper, and accessible liner. A standard sweep for a Redwood City single-family home with one fireplace runs $189 – $329, depending on flue height and the level of buildup. If you have a gas fireplace, a cleaning typically runs $149 – $249, and we inspect the pilot assembly, thermocouple, burner, and venting while we’re in there.
Here’s what we actually do on a Redwood City chimney sweep, start to finish:
Flue Brushing and Creosote Removal
We run a correctly sized wire or poly brush through the entire flue, removing creosote, the tar-like buildup that causes chimney fires, along with soot and any loose debris. In Redwood City’s flatland ranch homes, we often find more nest material than creosote, which we’ll pull out and show you. The flue is swept top-down with the firebox sealed so nothing enters your living room.
Cap, Crown, and Damper Check
After the sweep, we inspect the chimney cap, crown, and damper for gaps that let in rain, fog, and animals. In Redwood City, an uncapped flue on a postwar tract home is an open invitation to chimney swifts and raccoons. If you need a cap like an Olympia Chimney stainless model, we’ll quote it separately, with a written price before we install anything.
Gas Fireplace Cleaning in Redwood City
Gas Fireplace Cleaning in Redwood City homes means more than wiping the glass: we remove the burner, clean the ports, inspect the thermocouple and pilot assembly, and test the venting for proper draft. A gas fireplace cleaning in Redwood City runs $149 – $249, and it’s the service we recommend for homeowners who use their gas logs through the mild Peninsula winter without ever thinking about the inside of the unit. Even a clean-burning gas fireplace accumulates dust, pet hair, and carbon film on the glass and logs, and a blocked vent is a carbon monoxide risk.
Burner and Pilot Service
We disassemble the burner tray and clean each port so the flame pattern is even and blue, not yellow and sooty. A clogged burner in a Redwood City gas insert can send carbon monoxide into the room instead of up the flue. We test the thermocouple and thermopile with a multimeter, and if either is weak, we’ll show you the reading and quote a replacement before we touch anything.
Venting and Log Placement
Gas fireplaces in Redwood City homes vent through the chimney or a direct-vent pipe, and both need to be checked for blockages and proper draft. We also verify the log set is positioned exactly as the manufacturer specifies, because a log placed wrong can create soot, smell, and incomplete combustion. If the unit was converted from wood, we’ll confirm the conversion kit is correct and the damper is properly secured open.
Trusted Brands We Service in Redwood City
We install and service the same professional trade brands that chimney professionals specify, not box-store substitutes. That means DuraFlex liner systems, HeatShield resurfacing, Gelco stainless components, Olympia Chimney caps, Famco, and Copperfield. For Redwood City customers, carrying these brands locally means we can quote and schedule a repair without a second trip for parts. When a Stambaugh Hurst rancher needs a new liner or a Farm Hill custom home needs a Gelco crown seal, we already have the right material on hand, and we know how it performs in our specific fog-and-sun climate.
Common Chimney Sweep Problems We See in Redwood City Homes
- Wildlife nesting in uncapped clay tile flues. In Redwood City’s flatland tract neighborhoods like Stambaugh Hurst, chimney swifts and raccoons routinely colonize original clay tile flues that have never been capped. The mild climate means homeowners go five or more years between fires, and that’s plenty of time for a full nest to block the flue.
- Shared-flue cross-contamination in dense postwar tracts. Redwood City has many attached and closely-spaced homes from the 1940s and 1950s where a neighbor’s gas appliance vents into a shared masonry stack. When that happens, exhaust can push into your firebox, creating odor and draft problems that a simple sweep will not fix. This requires a camera inspection to trace the venting path.
- Fog-driven masonry decay in Emerald Hills and Farm Hill. The hillside microclimate of western Redwood City stays damp from marine fog much longer than the flatlands, and that sustained moisture cycles through brick and mortar. We regularly see chimney crowns with hairline cracks and mortar joints that have softened and spalled, letting water into the flue liner.
- Cracked clay tile liner joints in 60-to-80-year-old flues. The original clay tile liners in Redwood City’s postwar ranch homes are now well past their intended service life. Thermal expansion and settling crack the joints between sections, and once a joint opens, creosote and moisture get into the void behind the liner where a brush cannot reach them.

FAQs About Chimney Sweep in Redwood City
Yes, and it’s one of the most common issues we find in Redwood City’s attached and closely-built postwar tracts. Shared masonry stacks often have separate flue channels for each appliance, but when the internal wythes crack or the flue liners fail, exhaust from your neighbor’s furnace can migrate into your firebox. You’ll smell it as a sulfur or exhaust odor even when your fireplace is not in use. A Level 2 camera inspection will trace the venting path and show you exactly where the breach is. Call (336) 863-3889 and we’ll schedule the inspection with a technician who knows Stambaugh Hurst’s housing stock.
You need an inspection precisely because you haven’t burned a fire in five years. In Redwood City’s mild flatland climate, unused chimneys are the ones most likely to be fully blocked by raccoon or chimney swift nests, and the clay tile liners in 60-to-80-year-old ranch homes continue to crack whether you burn or not. A Level 1 inspection once a year, or any time before you light the first fire of the season, catches animal entry and liner failure before they become a chimney fire or carbon monoxide problem. It’s the cheapest insurance a Redwood City homeowner can buy for a fireplace.
Emerald Hills and Farm Hill sit in a fog belt that keeps masonry damp for hours after the flatlands near downtown Redwood City have dried out. That sustained moisture cycles through the brick and mortar joints, and the repeated expansion and contraction causes the mortar to crumble and the brick faces to spall. Downtown chimneys stay drier and age more slowly. If you live in the hills, an annual visual check of your crown and flashing is more than routine, it’s the difference between repointing and a full rebuild. We’ll show you photos of the joints we’re concerned about before we recommend any work.
Third-degree creosote is a hard, glossy, tar-like glaze that forms when chimney temperatures stay low and combustion is incomplete, common in Redwood City homes with older, leaky fireplaces. A standard wire brush will not remove it, and trying can damage the flue liner. We identify it during the sweep: if the brush skates over a hard, shiny deposit, we’ll show you a photo from the camera and recommend a chemical treatment or a HeatShield resurfacing, depending on the liner condition. You’ll get a written price for the fix before any material goes in.
A certified chimney sweep checks the entire gas fireplace as a system: the burner and ports, the thermocouple and thermopile, the pilot assembly, the glass gasket, the log placement, and the venting path all the way to the outside. In Redwood City, where many homes have original masonry chimneys converted to gas, we pay particular attention to the damper position and the condition of the old clay tile liner, because a cracked liner leaks exhaust into the wall cavity. The cost is $149 – $249 and includes a full safety check with a carbon monoxide reading at the firebox.
