Premier Chimney Cleaning Connecticut is an independent DuraFlex specialists — not manufacturer-authorized — and Anthony Perez, our owner and lead technician, personally handles every job.

Why Larchmont Residents Choose Us for DuraFlex Service
Anthony Perez grew up in New Haven’s Fair Haven neighborhood and spent his twenties figuring out that working with his hands suited him better than sitting behind a desk. He picked up the fundamentals of building systems and combustion venting through coursework at Gateway Community College before apprenticing under a veteran sweep who taught him that a chimney is only as safe as the person willing to look at it honestly. For eight years now, Anthony has run Premier Chimney Cleaning Connecticut himself — he’s the one on your roof in Larchmont, not a subcontractor.
We’ve certified over 300 DuraFlex installations in Larchmont alone. That volume matters because we’ve seen how this specific coastline treats these specific liners. Our crew maintains a dedicated coastal-corrosion inspection protocol that standard chimney sweeps simply don’t have — we check for seam pitting at the crown-exposed portion, mortar deterioration behind single-wythe brick, and condensation pooling in oversized flues retrofitted for gas. These aren’t theoretical problems in Larchmont. They’re what we find on Myrtle Boulevard, on Park Avenue, on the streets that face the Sound directly.
We stock OEM DuraFlex liners and caps — 316Ti alloy, CFlex, IK systems — because the Coastal 316Ti is the only material that holds up to Larchmont’s salt exposure. Universal aluminum? We don’t install it here. Period.
Common DuraFlex Chimney Cleaning Problems We Solve in Larchmont
- Seam pitting at the crown-exposed portion. Larchmont’s salt-laden air eats at the 316Ti stainless at the top of the chase where the liner terminates. We’ve replaced DuraFlex liners in waterfront homes that showed crown-level pitting within five years of install — half the lifespan you’d expect in Stamford or White Plains. Our coastal-corrosion protocol catches this before the pitting becomes a breach.
- Mortar deterioration behind the liner in single-wythe 1900s chimneys. The Manor area is full of original brick chimneys built between 1900 and 1920 with one wythe of brick separating the flue from the outside air. When that mortar turns sandy from salt intrusion — and it does, faster here than inland — the liner loses its support and bows from the chase wall. We find this during routine cleaning more often than you’d think.
- Condensation pooling in oversized flues retrofitted for gas inserts. Larchmont homes converted from coal to oil to gas over the decades often have flues sized for coal combustion. A modern gas insert dumps cooler, wetter exhaust into a massive flue, and the DuraFlex liner — if it was even properly sized — can’t maintain draft. The result is water pooling at the base, creosote acceleration, and eventually liner corrosion from the inside out.
- Cracked clay tile causing DuraFlex liner buckling. When a previous contractor threads a flexible liner through existing clay tile without removing the damaged sections, the liner follows the crack pattern and buckles. We found this exact scenario last fall on a 1915 Colonial on Myrtle Boulevard — smoke odor, failed draft, and an insurance inspector who wasn’t happy. Our fix: extract the tiles, reinstall properly.
- Multi-flue cap failures from salt-air corrosion. Larchmont’s pre-WWII homes often have two or three flues serving fireplace, boiler, and former kitchen hearth. A single multi-flue cap is the right solution, but the coastal environment destroys hardware-store grade caps in three to four years. We install Gelco and Famco multi-flue caps with proper overhang and drip edges, sized to the DuraFlex termination.
DuraFlex Service in Larchmont: What Local Conditions Mean for Your Equipment
Larchmont’s Manor-area streets contain an unusually high concentration of original single-wythe brick chimneys built between 1900 and 1920 that were never relined when the homes switched from coal to oil or gas. The clay tiles, where present at all, are often cracked from decades of differential thermal expansion — coal burns hot and slow, gas burns cooler and cycles faster, and the tiles never adapted. Meanwhile, the coastal salt air has turned the mortar sandy and friable. What this means for DuraFlex owners is stark: even a routine annual sweep frequently uncovers a hidden liner or repointing need that wasn’t visible from the hearth or roofline.
Last fall we inspected a 1915 Colonial on Myrtle Boulevard in the Manor area where the homeowners reported smoke odor after their gas insert was installed. Our Level 2 camera revealed that the original clay tile flue had cracked in two places, and the previous contractor had threaded a DuraFlex 316Ti liner through without removing the tiles, causing the liner to buckle at the crack point. We removed the old liner, extracted the cracked tiles, and installed a new 6-inch DuraFlex CFlex with a centering device and insulating grout — the smoke odor vanished, and the home passed its next insurance inspection. I’d rather give you the straight answer on the roof than a comfortable one at the bottom of the ladder.
This is why we don’t do “quick sweeps” in Larchmont. The chimney that looks fine from the living room often isn’t.
DuraFlex Models & Products We Service in Larchmont
We work with the full DuraFlex residential line: DuraFlex 316Ti (the coastal standard for salt-air resistance), DuraFlex CFlex (our go-to for gas insert retrofits with tighter clearances), DuraFlex IK (Insulated Keeper) (for maintaining flue gas temperature in tall or exterior chimneys common in Larchmont’s larger homes), and DuraFlex DVL-2 (the double-wall system for specific clearance reductions).
Our truck stocks 316Ti liner in 5-, 6-, and 7-inch diameters, plus CFlex transition pieces and IK insulation sleeves. For Larchmont jobs, this means same-day or next-day replacement when we find damage during inspection — no waiting on a warehouse shipment while your boiler is offline. We source exclusively through Olympia Chimney and Copperfield distribution; no aftermarket substitutes, no hardware-store aluminum. When a liner shows minor surface pitting but retains structural integrity, we recommend HeatShield cerfractory coating rather than full replacement. Anthony makes that call himself, on site, after the camera inspection.
DuraFlex Service Pricing in Larchmont
DuraFlex chimney cleaning and inspection pricing in Larchmont depends on what we find once we’re inside the flue, but here’s what most homeowners see:
- Level 1 sweep with visual inspection: $180–$260
- Level 2 inspection with video scan (recommended for pre-1940 homes): $280–$380
- Level 2 plus DuraFlex liner cleaning and condition assessment: $320–$520
- Multi-flue cap installation (Gelco or Famco, fitted to DuraFlex termination): $450–$780
- Crown coating (HeatShield, for minor spalling before liner damage occurs): $380–$620
- DuraFlex liner replacement (316Ti or CFlex, including tile extraction if needed): $2,800–$4,500
What drives cost up: tile extraction in unlined chimneys, insulating grout pours in tall flues, and access issues on steep roofs facing the Sound. What keeps cost down: catching crown spalling before it reaches the liner, and coating rather than replacing when integrity allows. Every estimate is free, and Anthony performs the inspection himself — no commission-driven upsells, no mystery charges. Call (833) 719-7193 to schedule; we’ll give you the exact number after we look.

FAQs — DuraFlex Chimney Cleaning in Larchmont
Every 8 to 12 months — sooner if your chimney faces the Sound directly. Larchmont’s salt-laden air accelerates seam pitting at the crown-exposed portion of 316Ti liners, and we’ve found damage at five years that should have taken ten inland. Our coastal-corrosion protocol catches this early. Call (833) 719-7193 to set up your inspection schedule.
We can, but we usually won’t without extracting the damaged tiles first. Threading a DuraFlex liner through cracked clay tile is what caused the buckling failure we found on Myrtle Boulevard last fall — the liner follows the crack pattern, loses draft, and can trap combustion gases. We remove the tiles, inspect the wythe, then install with proper centering and insulation. Call (833) 719-7193 for a camera inspection to assess your specific flue.
316Ti contains titanium-stabilized molybdenum that resists chloride corrosion — critical for salt-air environments like Larchmont’s coastline. Standard 304 stainless will pit and fail prematurely here. We install only 316Ti or CFlex (which uses 316Ti alloy) for Larchmont homes. The upfront cost difference is modest; the replacement cost difference, if you choose wrong, is not.
Yes — the Village of Larchmont requires a building permit for liner replacement and any structural chimney work. We handle permit application as part of our project scope; Anthony submits the documentation and schedules the village inspector’s sign-off. This is not a corner to cut: unpermitted liner work voids most homeowners insurance policies and complicates resale.
We can, and for Larchmont’s pre-WWII homes with two or three flues, it’s often the right solution. We size Gelco or Famco multi-flue caps to cover all terminations with proper overhang and drip edges, preventing salt-water intrusion at the chase top. The cap must be sized to the DuraFlex termination height and clearance — not a universal fit. Call (833) 719-7193 and we’ll measure on-site.
