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 Claremont, CA | Chestnut Chimney Sweep
We provide independent DuraFlex chimney cleaning, inspection, and repair across our Claremont service area. The work we do here is shaped by one thing: Claremont’s older homes, with original fireplaces and tree-heavy lots, put specific stress on DuraFlex systems you won’t find in newer neighboring cities. We’re not a manufacturer-authorized service center. We’re a team of chimney specialists who’ve worked on DuraFlex prefab and relining systems in Claremont’s 1920s-1940s bungalows long enough to know exactly how they fail here. Call us at (855) 360-4975 for a free estimate on sweeping, relining, or repair.
Why Claremont Residents Choose Us for DuraFlex Service
Roland Cifuentes, the owner at Chestnut Chimney Sweep, cut his teeth on fireplaces and venting systems across the Inland Empire after studying heating fundamentals at Chaffey College in Rancho Cucamonga. He’s spent the better part of two decades elbows-deep in everything from tract-home fireplaces to untouched 1980s masonry. When a DuraFlex liner needs attention in a Claremont village home, Roland can look at the adapter, the cap, and the firebox and tell you whether it’s a clean-and-go or a replace-now situation. That’s the DuraFlex sales & service knowledge we bring to every job.
Claremont homeowners call us because we stock genuine DuraFlex OEM components for the parts that matter most: adapters, connectors, termination plates. For non-structural items like caps and dampers, we use quality aftermarket parts when they meet or exceed original specs. You get the right part for the job, not just whatever’s on the truck.

Common DuraFlex Chimney Cleaning Problems We Solve in Claremont
- Clay-tile liner cracking behind DuraFlex relines. Claremont’s hot, dry days and sharp overnight temperature drops expand and contract original clay-tile liners in 1920s-1940s brick fireplaces. That movement stresses the DuraFlex stainless liner installed inside, sometimes cracking the clay behind it. We inspect for spalling before every sweep.
- Screened caps clogged with sycamore and eucalyptus litter. After a Santa Ana wind, caps on DuraFlex direct-vent terminations collect dry leaf debris from Claremont’s mature tree canopy. A clogged screen chokes draft, pushes smoke back into the living room, and shortens the life of the cap itself.
- Corrosion at the top plate or adapter on rarely used systems. Claremont’s long dry season means some fireplaces go months without use. Limited airflow plus condensation cycles can corrode the stainless top plate or adapter where the DuraFlex liner connects. We see this often on college-adjacent homes that only burn during the holiday stretch.
- Damper and firebox wear in DuraFlex gas systems. Dust intrusion in older village homes, combined with seasonal use patterns, wears dampers and firebox components in DuraFlex direct-vent gas fireplaces faster than in newer, tighter-built construction.
- Creosote build-up in DuraFlex ProFlex wood systems. Claremont’s cool winter evenings bring regular wood burning. In a ProFlex liner with even a slight offset or dip, creosote accumulates faster. Our cleaning process addresses the flex points specifically, not just the straight runs.
DuraFlex Service in Claremont: What Local Conditions Mean for Your Equipment
Here’s what makes DuraFlex work in Claremont different from neighboring cities like DuraFlex repair in Upland or Pomona. Claremont’s college-adjacent blocks, especially near the Claremont Colleges and the village, sit under some of the strictest historic-preservation and architectural-commission review in the Inland Empire. That means a DuraFlex reline job on a 1930s bungalow often has to work within the original fireplace dimensions. You can’t always swap in a modern cap or alter the firebox opening without a design review. We plan reline and cap replacement work around those original dimensions and screened-cap styles that satisfy architectural guidelines. In neighboring cities with looser review, a homeowner might get a standard cap slapped on the same week. In Claremont, the right approach is a custom multi-flue cap that keeps the original look. That’s the difference between a sweep who’s worked here and one who hasn’t.
Last fall, a homeowner on a tree-lined street near the Claremont Colleges called about smoke backing up from a DuraFlex direct-vent fireplace in a 1930s bungalow. Our tech found the cap screen packed with sycamore leaves after a Santa Ana wind event and a cracked clay-tile liner behind the DuraFlex adapter. We cleared the cap, replaced the adapter with an OEM part, and installed a custom multi-flue cap that met the historic overlay requirements. A clean flue is a quiet house – that’s really all there is to it.

AfterDuraFlex Service Pricing in Claremont
What you’ll pay depends on what we find. A standard sweep and Level 2 inspection on a DuraFlex system in Claremont typically runs in the low hundreds. If we find a clogged cap, that’s a cap replacement added on. A cracked clay-tile liner behind a DuraFlex reline means more involved work. We don’t quote blindly over the phone. We come out, inspect, and give you a price before any work starts. The free estimate includes a camera inspection and a photo report so you can see exactly what we see. Call (855) 360-4975 to schedule yours.

FAQs – DuraFlex Chimney Cleaning in Claremont
Yes, in many cases you do. Claremont’s architectural commission reviews exterior changes to older homes, and that includes visible chimney caps and terminations in some village and college-adjacent zones. We’ve worked with these requirements long enough to plan cap replacements and relines that keep the original look while meeting current safety standards. Call (855) 360-4975 and we’ll tell you what applies to your street.
Annually, at minimum. The Santa Ana winds load your cap with leaf litter, and the hot-dry/cool-night temperature swing works on the original clay-tile liner behind your DuraFlex system. A yearly Level 2 inspection catches adapter corrosion and spalling before they become a fire or carbon monoxide issue.
You can dust the glass and vacuum the firebox, but the venting itself needs a professional. Direct-vent systems have sealed combustion paths. A partial clog from leaf litter or a deteriorating adapter isn’t something you’ll spot from the living room. We scope the entire run, from firebox to termination, and clear what’s actually blocking draft.
Smoke backing into the room, a persistent downdraft smell, visible rust at the top plate, or crumbling clay-tile debris in the firebox all point to repair, not just cleaning. If your chimney was relined years ago and the original masonry behind it is failing, the liner is only as stable as what it sits in. We’ll camera-inspect before recommending anything.
Yes. We clean and repair DuraFlex ProFlex wood systems and DuraFlex Direct-Vent gas systems. Gas fireplaces still need annual service: burners get dusty, dampers stick, and terminations clog with Claremont’s leaf litter just like wood systems. Call (855) 360-4975 to book either.
