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.

AfterDuraFlex Chimney Cleaning in New Haven, CT | Hearthstone Chimney Co.
DuraFlex chimney cleaning in New Haven typically costs $180-$340 for a standard sweep and inspection, with multi-flue rental properties running higher due to access complexity. What makes our DuraFlex work different here is the city’s pre-1940 housing stock - stacked flues in two- and three-family rentals, originally built for coal, now serving oil boilers and wood fireplaces through the same masonry chase. We’ve been our Chimney Cleaning & Sweep in New Haven, inspecting, and repairing these systems across New Haven for over 42 years. Call (475) 369-1614 for a free estimate.
Why New Haven Residents Choose Us for DuraFlex Service
We install and repair DuraFlex sales & service daily, so we know how 316L stainless, 304L, and aluminum alloys hold up when Long Island Sound salt fog meets a hundred-year-old brick chimney. Russell Haines, our owner, learned the trade through the building construction program at Los Angeles Trade-Technical College before coming east and putting in more than two decades on Connecticut chimneys. He and our crew have worked every corner of New Haven service area - from the colonials near Sleeping Giant in Hamden to the brick stacks lining Whitney Avenue.
We’re not authorized by DuraFlex. Our credibility comes from field work: pulling a camera through offset flues in Fair Haven, spotting creosote migration between units in the Hill, replacing top plates corroded by coastal weather. Our 90-Day Done Right Promise covers every job in writing - no paperwork, no arguing. A live person answers the phone 24 hours a day. Background-checked, uniformed technicians. Most jobs done in one visit. Photos you can see, a plain-English verdict.
Russell has a saying he picked up over twenty years of inspections: “If it’s there, I’ll find it. If it doesn’t need fixing, I’ll tell you that too.” That is the standard we hold to.
Common DuraFlex Chimney Cleaning Problems We Solve in New Haven
- Pitting and crevice corrosion on 304L liners - New Haven’s salt-laden coastal air, especially on the east side toward the Sound, eats at 304L stainless faster than 316L. We find rust flakes at connector joints and the top of the liner where storm collars have failed. In wood-burning flues, this corrosion accelerates where creosote holds moisture against the metal. We inspect with a camera, document the pit depth, and replace with 316L if the wall thickness is compromised.
- Compression or kinking in offset flues - Pre-1940 New Haven brick chases often have corbeled offsets or narrow throats that force an uninsulated flexible liner into a tight bend. The restriction traps creosote, reduces draft, and can reverse smoke flow into living spaces. Our crew measures the flue path before selecting liner diameter and insulation package, and we reline rather than force a fit.
- Failed top plates, storm collars, and cap fasteners - Long Island Sound nor’easters drive horizontal rain and salt fog into chimney crowns. Standard fasteners corrode in three to five years here versus seven to ten inland. We stock DuraFlex multi-flue caps and custom caps with marine-grade hardware, and we seal the top plate with high-temp silicone rated for coastal exposure.
- Insulation wrap deterioration in mixed-use chimneys - In Fair Haven and the Hill, we regularly find boiler exhaust and wood smoke sharing one masonry chase with no separation liner. The temperature differential between the two flues shifts insulation blankets, creates cold spots, and accelerates creosote condensation. We install separate DuraFlex liners with proper insulation for each appliance and cap them with a multi-flue cover.
- Creosote migration between rental units - When a single exterior chimney serves an oil boiler on the first floor and a wood fireplace on the second, cracked clay tiles let combustion gases drift between floors. Tenants smell it, landlords get calls, and nobody knows the source until we run the camera. Cleaning alone does not fix this; the liner configuration does.
DuraFlex Service in New Haven: What Local Conditions Mean for Your Equipment
New Haven’s housing stock is dominated by pre-WWII two- and three-family wood-frame rental homes - many serving the large Yale and Southern Connecticut State University rental market - where a single brick chimney typically contains stacked flues serving separate units, originally sized for coal then adapted for oil or gas. This multi-flue, multi-tenant configuration creates liner deterioration and backdrafting risks that are fundamentally more complex than suburban single-family chimney work, and landlord turnover cleaning demand peaks sharply in August before the academic rental cycle begins.
In New Haven’s coal-to-oil conversion chimneys, original clay flue tiles are frequently undersized for modern gas and oil appliances and cracked, so a DuraFlex liner is often the only way to bring a pre-1940 two- or three-family rental chimney up to a safe, correctly sized flue. This is not the same problem as a suburban single-family chimney with one appliance and one flue. In Fair Haven, we opened a two-family rental chimney where the first floor had an oil boiler and the second floor had a wood fireplace, and the shared chase let creosote odor drift between units. Our crew ran a camera, found cracked and undersized clay tiles with no separation liner, then installed an insulated DuraFlex 316L liner for the boiler and a separate DuraFlex liner for the fireplace, sealed both with a multi-flue cap, and swept the system clean for the August turnover - a typical Chimney Repair - New Haven scenario.
The coastal freeze-thaw cycle - often multiple thaws per winter - opens hairline cracks in mortar beds that inland cities like Hartford see less frequently. Water gets in, freezes, expands, and the chase deteriorates faster than the liner inside it. We address both: the liner for safe venting, the masonry for structural integrity.
DuraFlex Models & Products We Service in New Haven
We work with the full DuraFlex product line: 316L and 304L stainless steel flexible chimney liner kits, insulated flexible liner systems with wrap or poured insulation, aluminum flexible liners for gas appliances, and multi-flue caps and custom caps. Our New Haven warehouse stocks genuine DuraFlex liner components, top plates, storm collars, and cap hardware for same-day replacement when corrosion or wind damage strikes.
Our parts stance is simple: genuine DuraFlex components for exact-fit replacements, UL-listed aftermarket stainless or aluminum only when they match the original alloy, diameter, and listing. If a liner is pitted through, kinked, or unlisted for the appliance, we recommend replacement rather than patching. If only the cap, top plate, or insulation has failed, we repair it. No surprises on the bill - the number on the estimate is the number on the invoice.

FAQs - DuraFlex Chimney Cleaning in New Haven
Yes, if the two flues serve different appliance types - especially a boiler below and a wood fireplace above. Connecticut code and basic safety require separation between combustion zones. In pre-1940 New Haven chimneys with cracked clay tiles, exhaust gases and creosote vapors migrate between floors through the shared masonry. We run a camera to confirm the flue condition, then size separate DuraFlex liners for each appliance and cap them with a multi-flue cover. Call (475) 369-1614 for a free inspection.
Salt-laden coastal air from Long Island Sound accelerates corrosion on 304L stainless, which is less resistant to chlorides than 316L. Rust flakes at the top joint or storm collar usually mean the alloy is wrong for the exposure, or the cap and collar have failed and let salt moisture sit on the metal. We inspect the pitting depth with a camera; superficial staining gets cleaned and resealed, but through-pitting requires replacement with 316L and a properly sealed cap assembly.
We can clean and inspect both flues, but we will not sweep the wood fireplace without first confirming that the separation between flues is intact. In the Hill and Fair Haven, we find shared chases with no liner separation and cracked clay tiles that allow creosote and exhaust to move between units. If the camera shows cross-contamination risk, we document it and recommend lining both flues separately before any burning season begins. Safety first, sweep second.
New Haven’s salt fog, horizontal wind-driven rain from nor’easters, and frequent freeze-thaw cycles corrode fasteners and mortar joints faster than Hartford or Waterbury see. A top plate that lasts eight years inland may fail in four here. We specify marine-grade hardware and inspect crown and cap condition as part of every DuraFlex service. The liner itself is protected inside the flue; the failure point is almost always the exterior seal.
A Level 2 inspection covers the accessible portions of the chimney structure, the liner interior with a video camera, the appliance connection, the top plate and cap assembly, and the clearance to combustibles. You receive photos of every stage and a written verdict in plain English - no jargon, no scare tactics. If the liner is sound, we say so. If it needs repair or replacement, we show you exactly why.
