Chimney sweep logs do not sweep chimneys. They loosen some creosote - which then falls where a brush and vacuum still have to collect it.
DuraFlex Chimney Cleaning in Clovis, CA | Alcott Chimney Fresno
A Chimney Sweep in Clovis for DuraFlex systems typically runs $189 – $289 for a standard cleaning, depending on liner condition and accessibility. We’re Alcott Chimney Fresno, an independent DuraFlex service provider, and the work we do here is shaped by one fact no out-of-town outfit knows: Clovis tract homes with zero-clearance fireplaces bake creosote into a hard glaze during the idle summer months, so cleaning is rarely a quick brush-through. If you’re seeing smoke roll back into the room or smell something sharp when the fire gets going, call (559) 215-1714 and we’ll explain exactly what we’re looking at.
Why Clovis Residents Choose Us for DuraFlex Service
We service and install DuraFlex sales & service across the central Valley, and in Clovis specifically, we’re familiar with the tract-home layouts and older masonry stacks that determine how a liner wears. We carry the measurement and fastening tools needed to work on flexible stainless liners without chewing up the chase or flue tile around them. Ruben Castellano, our owner, came up through Los Angeles Trade-Technical College and has spent nearly two decades on California chimneys. His rule is simple: the written price arrives before any tool leaves the van, and every repair carries a written guarantee. If a repair fails within the 365-Day Done Right Promise, the second visit is free. Tell me what you’re seeing and I’ll tell you what it actually means.
No vague estimates, no surprise line items. Our technicians are background-checked, identity-verified, and sent to you by name and photo before arrival, with a photo ID badge required at the door. That’s the Threshold Standard, and it’s not optional.

Common DuraFlex Chimney Cleaning Problems We Solve in Clovis
- Hardened creosote glaze in 304L liners from idle summers. Clovis fireplaces sit unused from May through October. Creosote left in a DuraFlex 304L liner hardens into a tar-like glaze that a standard brush won’t touch. We see this constantly in older tract subdivisions, and it’s the number one reason first-burn nights get smoky.
- Starling nests collapsing the top section of flex liners. North of Shaw Avenue, starlings build aggressively during the long dry season. We’ve pulled nests from between the DuraFlex liner and the original clay flue that buckled the flexible wall inward. This isn’t a cleaning problem; it’s a partial blockage that requires removal before sweeping.
- Pinhole corrosion in 316TI liners on wood-burning units. Creosote acids sitting against a 316TI liner all summer eat at the stainless. Clovis’s hot, dry summers accelerate this. If you’re seeing rust-colored flakes in the firebox, the liner’s likely compromised, and we’ll show you the camera footage before recommending anything.
- Slipped Pro Connect couplings after thermal cycling. Clovis’s cool, damp winter mornings followed by hot afternoon fires cause expansion cycles that can detach a Pro Connect coupling. We find these leaks during Level 2 inspections, often in two-story homes where the liner runs through an offset flue path.
- Ovalized or kinked liners from DIY pulls through tight zero-clearance chases. A flexible liner pulled through an offset without proper guidance kinks at the bend. We’ve repaired 304L liners that were flattened by more than 20% in tight chases. At that point, honestly, a patch isn’t the right call; a replacement section is.
DuraFlex Service in Clovis: What Local Conditions Mean for Your Equipment
Clovis city ordinance requires a Chimney Inspection in Clovis at Level 2 for any home sale that includes a factory-built or masonry fireplace. That creates a predictable wave of DuraFlex liner certifications every late summer, before school-year moves. In the Harlan Ranch and Loma Vista subdivisions, we schedule a run of inspections every August that are not routine sweeps; they’re documentation jobs for escrow. The 1980s-2000s tract stock in Clovis skews heavily toward pre-fab wood-burning fireplaces with zero-clearance chases, and those units hide problems longer than masonry stacks do. A cracked refractory panel behind the liner, a shifted Pro Connect coupling, a starling nest wedged at the top of the flex: none of these announce themselves until a Level 2 inspection camera goes up. That’s why we run a camera on every Clovis inspection, not just the ones for sale. You get the footage, not a summary.
DuraFlex Models & Products We Service in Clovis
Our techs work on the full DuraFlex line: the 304L Flexible Chimney Liner, 316TI Flexible Chimney Liner, Pro Connect Liner System, and Smooth Wall Liner. When structural integrity matters (liner walls, couplings, terminations), we use genuine DuraFlex components. For minor adapters and caps, we’ll source equivalent UL-listed parts to keep replacement costs sane. We stock common Pro Connect components and termination caps locally for faster Clovis turnaround, so you’re not waiting on a parts shipment from Ohio to get a reline finished. If you’ve got a DuraFlex smooth-wall liner that’s been in service for a decade, we can inspect it, rotary-sweep it, and tell you honestly whether it has another decade in it.

AfterDuraFlex Service Pricing in Clovis
A standard DuraFlex chimney sweep in Clovis runs $189 – $289. That’s before any repairs. A Level 2 camera inspection adds $99 – $149 when bundled with a sweep, and it’s the only way to know what’s actually happening inside a liner, especially after a starling season or a long idle summer. Creosote removal with poly rods, cap replacement, and Pro Connect coupling repairs are priced separately, always with a written quote before work starts. What drives cost here: liner length, access (two-story tract homes with steep rooflines cost more than single-story ranches), and whether we’re clearing glazed creosote or just routine soot. Call (559) 215-1714 for a free estimate. We’ll walk you through what we’re checking before we ever touch the chimney.

FAQs – DuraFlex Chimney Cleaning in Clovis
Yes, if the liner walls are intact and properly connected. We’ve certified 25-year-old 316TI liners in Old Town Clovis masonry chimneys when the stainless shows minimal pitting and the couplings are tight. But a 1990s liner that’s been through two decades of Clovis’s idle summers and active winters may have creosote glaze or hidden seam corrosion. We’ll run a camera and give you an honest read. Call (559) 215-1714 to schedule an inspection.
A smooth-wall liner has a nearly flat interior surface, so creosote and soot don’t accumulate as quickly as they do in the corrugations of a standard liner. In Clovis, where chimneys sit idle for months, that matters: creosote that would bake into corrugated ridges slides more readily off a smooth wall. The tradeoff is flexibility; smooth-wall liners don’t bend as easily through tight offsets. We’ll measure your flue path before recommending one over the other.
Yes, if the kink hasn’t ovalized the liner past the point of safe repair. A minor kink can sometimes be corrected with a proper pull technique and a reinforcing coupler. If the liner shows more than 20% ovalization or cracked seams at the kink, we’ll recommend replacing that section rather than patching it. We’ve fixed installs from other companies in Clovis more times than we can count, and we won’t shame anyone for it; we’ll just fix it right and show you the before-and-after camera footage.
A cold liner during burning usually means the draft is moving so poorly that the flue gases aren’t warming the stainless. That can be a blockage (a starling nest in Clovis subdivisions, for instance), a collapsed top section, or an improperly sized liner for the firebox. A Level 2 inspection will identify the cause in one visit. Call (559) 215-1714 and we’ll schedule it before you burn again.
We use rotary poly rods and specifically sized brushes that won’t mar the smooth-wall surface, coupling them with a vacuum system rated for fine soot. Direct-vent gas inserts produce a fine, dry soot that standard chimney brushes don’t remove well. We adjust our sweep method to the liner type and the insert’s burn pattern, and we’ll show you the liner after the sweep with our camera. Call (559) 215-1714 for a quote.
