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.

AfterFast, Reliable Chimney Sweep Across Fresno
A standard chimney sweep in Fresno typically runs $189 – $289, and most jobs are completed in 60 – 90 minutes. That price covers the full flue, smoke shelf, damper, and firebox, plus a camera check of what’s actually going on inside your chimney before we call the job done. We’re Alcott Chimney Sweep, and we’ve been doing this work since 2002. If you live anywhere in Fresno, call (336) 863-3889 and you’ll speak to a live person, not a voicemail tree.
Why Alcott Chimney Sweep Is Fresno’s Preferred Chimney Sweep Company
Homeowners in Fresno deal with a chimney reality that most national sweep companies don’t understand: the San Joaquin Valley Air Pollution Control District issues No Burn days all winter long, so flues sit cold and damp for weeks, then get hammered during the short windows when burning is legal. That cycle creates creosote and animal-nesting problems you simply don’t see in cities with unrestricted burning. Our technicians know this because they work in Fresno neighborhoods every week, from the Tower District to the newer subdivisions north of Herndon Avenue.
We send background-checked, identity-verified technicians, and you’ll know the technician’s name and see their photo before we arrive. That’s the Threshold Standard, and it’s not an optional upgrade. Every Fresno customer gets a written price before any work starts, a written guarantee on every repair, and a free second visit if a repair fails within the coverage period. We’re led by Ruben Castellano, who built this company on the idea that certainty matters as much as clean work.
Gas Fireplace Cleaning in Fresno
Gas Fireplace Cleaning in Fresno is a service we handle constantly, especially in the 1990s and 2000s homes across north Fresno where factory-built zero-clearance units are standard. A gas fireplace doesn’t produce creosote, but it does collect dust, pet hair, soot from incomplete combustion, and often spider webs or insect nests inside the burner ports and pilot assembly. You’ll notice it when the flames burn lazy and yellow instead of crisp and blue, or when you smell a dusty odor during the first few minutes of operation. In Fresno, we recommend this cleaning annually, ideally in late fall before the first sustained cold snap.
A gas fireplace cleaning in Fresno typically runs $149 – $229. That includes removing the glass, cleaning the burner and pilot, vacuuming the firebox, and checking the venting for blockages. You get camera documentation, not a verbal “looks fine.”
Burner and Pilot Service
Fresno’s summer dust season means burners here clog faster than in coastal cities. We clean the burner ports, test thermopile and thermocouple output, and verify the pilot flame is strong. If your fireplace has been lighting slowly all season, this usually fixes it.
Glass and Log Cleaning
We remove the glass panel, clean off the mineral haze that develops from burned dust, and reposition your log set per the manufacturer’s original layout. Safety note: never attempt to remove the glass on a gas fireplace yourself. The tempered glass must seat properly, or carbon monoxide can enter the home.
Chimney Maintenance in Fresno
Chimney Maintenance in Fresno means something different than it does in Houston or anywhere with unrestricted burning. Here, your flue can sit unused for six or eight weeks during a long stretch of No Burn days, then get pushed hard for a solid week when the air clears. That idle-then-heavy pattern lets creosote harden, moisture condense on clay tile liners, and birds move into unused fireboxes. The most valuable maintenance step a Fresno homeowner can take is an annual level 1 inspection in September or October, before burning season starts and before the first real fog inversion settles over the valley.
Annual maintenance, which includes a sweep plus a Level 1 inspection, runs $189 – $289 in Fresno. If we find damage that needs repair, you’ll see it on camera before any recommendation is made, and you’ll get a written price before any work begins.
Pre-Season Inspection
We check the crown, cap, flashing, liner, damper, and firebox. In Fresno, cracked crowns are unusually common because summer temps over 105°F expand the masonry, and winter fog keeps it damp. If your crown has small cracks, we can seal them before water gets in and makes them worse.
Waterproofing and Crown Seal
Fresno’s Tule fog is persistent enough to saturate exposed masonry for days at a time. We apply professional-grade CrownCoat sealant to absorbent crowns and, where needed, water repellent to the upper chimney exterior. It’s far cheaper than rebuilding a spalled crown after another wet winter.
Trusted Brands We Service in Fresno
We install and service professional trade materials, not box-store substitutes. When a Fresno chimney needs a new liner, we quote DuraFlex stainless or HeatShield resurfacing, depending on what the camera shows. For gas fireplace repairs, we stock Famco and Copperfield replacement parts locally, which means faster turnaround for Fresno homeowners than a shop ordering from a distributor and waiting a week. If your chimney has an Olympia Chimney cap or damper, our techs are trained on those specs directly. We use the same brands chimney professionals specify, because your flue carries fire and carbon monoxide, and that’s not a place for improvised parts.
Common Chimney Sweep Problems We See in Fresno Homes
- Third-degree creosote glaze in cold, damp clay-tile flues. Fresno’s Tule fog inversions leave flues damp for months. When you finally burn, the combination of moisture and a cold tile liner bakes creosote into a hard glaze that a standard brush alone can’t fully remove.
- Starling and Screech-Owl nesting in the firebox or lower flue. Homes near the Tower District and central Fresno that skip three or more seasons of burning often become bird housing. We find European starlings and Western Screech-Owls nesting in the lower flue more often than any other Fresno failure mode.
- Cracked crowns and spalling mortar from 105°F summer heat. Thermal expansion over twenty-plus brutal Fresno summers cracks chimney crowns and loosens mortar joints before you ever light a fire. A Level 1 visual check often misses this; a camera close-up doesn’t.
- Appliances vented into original 1950s – 1980s clay-tile flues. Many Fresno homes vent water heater exhaust into the same clay liner that used to serve the fireplace. If that liner has spalled, exhaust gases can leak into wall cavities, which is exactly why we check with a camera before saying “you’re fine.”

FAQs About Chimney Sweep in Fresno
Because Fresno’s No Burn days mean your chimney sat cold and damp for months, which invites condensation, mortar deterioration, and bird nesting even in a flue you never used. We answer this with a camera: we’ll show you exactly what’s in there, whether it’s a starling nest or just surface soot. If nothing’s wrong, you’ll see that too, and you’ll know you’re safe to burn when the next legal burn window opens. Call (336) 863-3889 to book that camera inspection.
In the Tower District and central Fresno, we’re almost always working on 1950s – 1980s masonry chimneys with original clay tile liners, often showing spalling and creosote glaze from years of heat-cycling and fog moisture. In north Fresno, we’re typically servicing factory-built zero-clearance metal fireplaces from the 1990s and 2000s, which have different clearances, smaller flues, and their own set of maintenance requirements. Our techs know which procedure fits which side of town, and we stock parts for both.
Because we don’t recommend a liner, a crown rebuild, or anything else without showing you camera footage that documents the problem. If your clay tile liner is intact and the flue is clean, we’ll tell you that plainly, and you won’t get a pitch for work you don’t need. If the camera shows spalled tiles or a gap where the liner has failed, you’ll see it on the monitor with your own eyes before any price is quoted. That’s the standard Ruben Castellano set from day one, and it applies on every Fresno job.
Yes. Chimney crowns and mortar joints sit exposed to 105°F-plus heat for weeks every summer in Fresno, and that heat expansion cracks masonry over time. When the Tule fog arrives later in the year and saturates that cracked masonry, the damage accelerates. By the time you light your first fire, a crown can already be failing. That’s why we recommend an inspection in September or early October, not January.
Third-degree creosote is the hardened, glaze-like form that builds up when creosote is repeatedly heated and cooled in a damp flue, and in Fresno the fog inversions make this more common than in drier climates. It won’t come out with a standard brush-only sweep; it typically requires mechanical removal or chemical treatment followed by a recheck. Left in place, it’s a chimney fire fuel source. If we find it, you’ll see it on camera, and we’ll quote you a written price for the removal method that fits your situation. Call (336) 863-3889 to schedule an inspection and find out what’s actually in your flue.
What You Should Do Next
You live in a city where your chimney’s worst problems often develop while you’re not using it. No Burn days, Tule fog, and 105°F summers work against your flue all year, whether you’re lighting fires or not. The fix is simple: have a camera inspection done before burning season, see what’s actually there with your own eyes, and get a written price for only the work the evidence supports. Call (336) 863-3889 and you’ll speak to a live person who can schedule your Fresno chimney sweep or inspection. You’ll know your technician’s name and see their photo before we ever pull into your driveway.
