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 Fresno
A standard chimney sweep in Fresno typically runs $189 – $289 before any repairs, and a Level 1 inspection usually adds $99 – $149. We book most sweeps within 3 to 5 business days, and we’ll give you a written price before any work starts. If you’re in central Fresno, Clovis, or anywhere else in the metro, our crews know the housing stock you’re living with because we’ve swept thousands of these chimneys since 2002. Call (559) 215-1714 and you’ll get a live person, not a voicemail tree.
What makes a Fresno chimney different isn’t the fireplace itself. It’s the heat. Months of 100-degree summers bake the masonry, then short, cold snaps in December and January push smoke through flues that have been sitting unused since March. That cycle creates a very specific kind of problem, and the big national franchises don’t usually catch it. We do, because this is the only place we work.
Why Alcott Chimney Fresno Is Fresno’s Preferred Chimney Sweep Company
We’re the Chimney Sweep team homeowners call when they want to know exactly who’s showing up. Before the truck leaves our Fresno, Central Valley office, you get the technician’s name and photo. When they knock, they show a photo ID badge. That’s the Threshold Standard, and it’s not optional on any job we run in Fresno.
Fresno homeowners tend to be direct, and they don’t love surprises. Ruben Castellano built this company on that same instinct. Every customer gets a written price before work begins. Every repair carries a written guarantee. If a repair fails within the coverage period, the second visit is free. The 365-Day Done Right Promise isn’t a slogan. It’s a full year of accountability, in writing, on every completed job.
We answer the phone around the clock with a live person. When smoke backs up into the house at 11 p.m. in Woodward Park, you don’t want a callback queue. You want someone who can tell you whether to close the damper, open a window, and whether a tech should come now or in the morning.
Styles & brands we work with





Chimney Sweep Certified in Fresno
Chimney Sweep Certified in Fresno means the sweep removes creosote, soot, and the blockages that cause chimney fires, then verifies the flue is clear with a camera, not just a wire brush and a good feeling. A typical certified sweep in Fresno runs $189 – $289, depending on flue height, access, and how long it’s been since the last cleaning. Homes in the Tower District, Fresno High area, and Old Fig Garden with original brick chimneys often run toward the higher end because the flues are taller and the deposits are older. If your fireplace hasn’t been used in ten months and you fired it up the week before Thanksgiving, expect heavier creosote than a home with a gas insert that gets used all winter.
Creosote and Soot Removal
Creosote is the tar-like residue from wood smoke that hardens into a glaze inside the flue. Third-degree creosote can’t be brushed off. It has to be removed with rotary tools and sometimes chemical treatments. We always show you the camera feed before and after, so you can see what came out and what’s left.
Annual Sweep and Fireplace Cleaning
An annual sweep in Fresno makes sense before the burn season starts, usually October. That’s before the first inversion and before the air district starts calling no-burn days. We clean the smoke chamber, damper, and firebox, then run the camera so you can see the flue is actually clear.
Gas Fireplace Cleaning in Fresno
Gas Fireplace Repair - Fresno starts with cleaning, and it’s a different job than a wood-burning sweep, one a lot of companies skip or half-do. We remove the glass, clean soot off the logs or media, check the burner ports, inspect the thermocouple and pilot assembly, and verify venting is clear. A gas fireplace cleaning in Fresno runs $149 – $199. If it’s a direct-vent unit that’s been running all winter in northeast Fresno, hairline soot buildup on the glass is normal. If the flames are yellow and lazy, that’s a venting or air-shutter issue, and it needs to be addressed before carbon monoxide becomes a real concern.
Vented Gas Log Maintenance
Vented gas logs in older Fresno homes need the chimney swept, too. The gas flame doesn’t produce much creosote, but the chimney still vents combustion byproducts, and birds and debris still get in. We sweep the flue, check the damper clip, and make sure the log set is burning clean.
Direct-Vent and Insert Service
Direct-vent units don’t use the old masonry flue, but they still need the vent termination inspected and the burners cleaned. Lint, pet hair, and central valley dust collect in the burner ports. That’s the main cause of the “gas smell” people report from units that haven’t been serviced in years.
Trusted Brands We Service in Fresno
We stock and install materials from the brands chimney professionals actually specify, not whatever is on the shelf at the big box store. When a Fresno home needs a new liner, we quote DuraFlex repair in Fresno or Copperfield. When a flue has spalling but is structurally sound, we talk about HeatShield resurfacing. We also work with Gelco and Olympia Chimney caps and dampers. Because we keep these materials in stock for the Fresno market, a liner job in Sanger or a cap replacement in the Tower District doesn’t wait on a slow out-of-state shipment. That matters when the first rain is coming and your chimney is leaking.

AfterCommon Chimney Sweep Problems We See in Fresno Homes
- Spalled clay tile from disuse and heat cycling. Fresno’s summer heat expands the clay liner, then winter’s damp cold contracts it. Over 60 or 70 years, chunks of tile flake off into the flue and trap creosote. A sweep-and-go crew that never looks with a camera won’t see it. We do, and we show you the video.
- Third-degree creosote that wire brushes just polish. After a long dormant stretch, creosote hardens into a shiny tar glaze. Brushing makes it look smooth but doesn’t remove the fuel load. We use rotary equipment to break that glaze, then the camera confirms it’s gone.
- Cracked ‘Fresno cap’ on older central Fresno chimneys. The flared concrete top popular from the 1920s through the 1940s is prone to cracking right at the flare, where the material is thinnest. Water gets in, freezes on cold nights, and widens the crack. We inspect every cap visually and mention it if it’s weeping rust stains or showing a hairline crack.
- Moisture-swollen creosote in damp winter flues. When a cold, unused flue meets the valley’s damp December air, creosote absorbs moisture and turns glue-like. If a sweep vacuums too early, it smears instead of removes. We let the flue dry or use a rotary head that shears it off before vacuuming.

FAQs About Chimney Sweep in Fresno
The ‘Fresno cap’ was cast with a flare that’s thinnest at the widest point, and seventy to ninety years of summer heat followed by damp valley winter air fatigues the concrete right there. The crack is usually at the flare’s shoulder, and it lets water into the flue and the top courses of brick. We spot it during a sweep, seal it with a breathable sealant rated for Fresno’s temperature swings if it’s minor, and tell you honestly when it needs a full recast. Call (559) 215-1714 and we’ll take a look before the next winter rain.
No. The San Joaquin Valley Air Pollution Control District’s wood-burning restrictions apply on designated no-burn days regardless of how you heat your home, and burning on those days can draw a fine from local enforcement. Gas fireplaces are generally permitted, which is why a lot of Fresno homeowners keep a direct-vent gas unit as a backup for the cold snaps when wood burning is restricted. We can clean and service your gas fireplace even in peak burn season. Call (559) 215-1714 to book.
Once a year, before you light the first fire. It sounds like overkill for two months of use, but Fresno’s cycle is exactly what makes once-a-year right: the chimney sits unused for ten months, creosote from last winter hardens, masonry shifts in the heat, and small cracks open up. A yearly October sweep catches all of it before the first cold snap. We’ll book your next one on the spot and call to remind you in September. Call (559) 215-1714 to get on the schedule.
Maybe not. Sixty-year-old clay tile liners in Fresno homes commonly show spalling, cracking, and missing mortar joints between tiles, which lets heat and gases reach the surrounding masonry. A Level 2 camera inspection will tell you whether the liner is still doing its job or whether you need HeatShield resurfacing or a new stainless liner. We won’t tell you the chimney is dangerous just because it’s old, and we won’t sell you a liner based on age alone. You’ll see the camera footage and we’ll explain what it means. Call (559) 215-1714 for a Level 2 inspection with a written report.
Because you shouldn’t have to trust our word on a thousand-dollar repair. We run a camera through every flue we sweep in Fresno, and if we see spalled tiles, a cracked liner, or a failing damper, we bring you to the monitor and show you exactly what we’re seeing. Ruben Castellano set the rule: no repair is recommended without camera evidence the homeowner can see for themselves. If the flue looks fine, we tell you that, too. It protects you from being sold liners and masonry work you don’t need, and it protects our reputation in a market where word travels fast. Call (559) 215-1714 and you’ll get the same treatment on your first visit.
In Fresno’s Tower District, many chimneys have a distinctive 1920s-40s ‘Fresno cap’, a flared concrete top that cracks right at the flare. Our sweeps know to look for it because it’s a failure pattern you only learn by working these streets. We swept a 1938 bungalow in the Tower District where the clay-tile flue was shedding spalled fragments and the Fresno cap had a hairline crack at the flare. Our camera showed first-degree creosote crusting the smoke chamber and a rusting damper. We removed the glaze, recommended a HeatShield resurfacing for the flue liner, and packed the cap crack with a breathable sealant rated for Fresno’s summer heat. That’s what a real Fresno sweep looks like. It’s not a checklist. It’s knowing what these specific houses hide.
If you live in Fresno and your chimney hasn’t been swept this year, call (559) 215-1714. We’ll give you a written price, send a background-checked and identity-verified technician with a photo ID, and show you the camera footage before anything else happens. That’s the deal, every time.
