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.

Why Hearthstone Chimney Co. Is Hartsdale’s Preferred Chimney Liner & Rebuild Company
Hartsdale homeowners know their chimneys. Many have lived in the same 1920s Colonial or Tudor for thirty, forty, fifty years. They’ve watched prior owners patch and defer. They want someone who speaks plainly about what is actually wrong, documents it with photos they can see themselves, and fixes it without return visits.
That’s why we answer every call with a live person, 24/7. No voicemail, no callback queue, no app. Our technicians are background-checked and uniformed. Most liner replacements and partial rebuilds in Hartsdale are completed in a single visit with no-hassle upfront pricing - the estimate number matches the invoice number. Every job carries our 90-Day Done Right Promise in writing: if it’s not right, we come back. No paperwork, no arguing.
We know the local conditions cold. Westchester’s Hudson Valley winters push temperatures across the freeze-thaw line repeatedly from November through March, and Hartsdale’s dense concentration of century-old masonry takes the punishment harder than newer stock. Nor’easters track straight up the valley, dumping wet snow onto chimney crowns that were never designed for it. We’ve rebuilt crowns and replaced flashing on homes within sight of the Hartsdale Metro-North station and relined flues in the apartment buildings clustered nearby.
Our Chimney Liner & Rebuild Services in Hartsdale
Stainless Steel Liner Installation
For most Hartsdale fireplaces and wood-burning inserts, a stainless steel liner is the right fix. We use DuraFlex and Olympia Chimney products - not builder-grade substitutes - sized precisely to your appliance’s BTU output and draft requirement. In Hartsdale’s two-flue stacks, proper isolation matters. The stainless liner seals the fireplace flue from any cross-connection to an adjacent furnace flue or neighbouring vent, which is critical on attached-property blocks where stack separation can fail. A typical Hartsdale stainless installation runs $2,800-$4,500 depending on flue height, diameter, and whether the smoke chamber needs parging.
Flexible Liner Installation
Some Hartsdale chimneys have offsets or bends that rigid stainless cannot navigate, especially in the tighter construction of pre-war Tudors with angled flue passages. A flexible liner from DuraFlex conforms to these irregularities while maintaining the same UL-listed protection. We see this most often in homes near the Hartsdale train station where the original builders squeezed chimneys into narrow wall cavities. Flexible installations in Hartsdale generally fall between $3,200-$5,000 when offsets or multiple bends are involved.
Liner Replacement
When clay tile has cracked, shifted, or spalled beyond repair, replacement is the only safe path. In Hartsdale, this is common. The 1920s-1940s clay liners were never built to withstand a century of Westchester freeze-thaw cycling, and many were sized for coal furnaces with draft characteristics completely wrong for modern gas appliances or EPA-certified wood inserts. We remove the compromised tile, inspect the surrounding masonry with a Level 2 camera, and install a new liner system with proper insulation and top-sealing. Liner replacement in Hartsdale typically ranges $3,500-$5,500.
Partial Rebuild
Not every failing chimney needs to come down to the roofline. In Hartsdale, we often rebuild from the roof up - replacing a spalled crown, eroded brick courses, and deteriorated flashing while preserving sound masonry below. This is the right choice when the lower stack is solid but the crown has let water track down for decades, or when nor’easter snow loads have finally cracked the top courses beyond repointing. Partial rebuilds in Hartsdale start around $3,200 and can reach $6,500 for taller stacks with complex crown geometry.

Trusted Brands We Service in Hartsdale
We don’t substitute. Every liner, cap, and rebuild component we install in Hartsdale comes from professional-grade suppliers we’ve worked with for decades: DuraFlex for flexible and rigid stainless systems, Olympia Chimney for precision-fit liners and accessories, and Famco for caps and dampers engineered to Hudson Valley wind and weather.

Common Chimney Liner & Rebuild Problems We See in Hartsdale Homes
- Orphaned furnace flues left uncapped after fuel conversions. On attached blocks off East Hartsdale Avenue, we regularly find the second flue in a two-flue stack still open from a 1960s oil-to-gas switch. That opening can pull exhaust from a neighbour’s appliance into your stack, or let your fireplace draft backward. Westchester County and Town of Greenburgh codes require proper capping or decommissioning before a certificate of occupancy will issue.
- Clay tile cracked and offset by a century of freeze-thaw. Hartsdale’s 1920s-1940s chimneys cycle through the 32°F threshold dozens of times each winter. Water enters hairline cracks, expands, and pushes the liner apart. By year eighty or ninety, the tiles are loose, the mortar joints are powder, and a Level 2 inspection fails at home sale every time.
- Nor’easter snow loads eroding crowns and flashing. Wet, heavy snow sits on Hartsdale chimney crowns for days after a coastal storm. Poorly maintained caps let water migrate through freeze-thaw cracks, causing efflorescence on brick faces and water staining in fireboxes. We’ve rebuilt crowns on homes within blocks of the Hartsdale train station where the original concrete had simply turned to gravel.
- Cross-contamination between attached properties. This is the Hartsdale problem that doesn’t exist in detached suburbs. When two-flue stacks share a party wall or sit close on narrow lots, a failed liner in one unit can let combustion gases migrate into a neighbour’s flue. Proper stainless relining and capping isolates each vent path. We document the separation with camera evidence you can see.

FAQs - Chimney Liner & Rebuild in Hartsdale
Not necessarily both, but both need proper termination. In Hartsdale’s 1920s-1940s housing, the second flue often served a coal or oil furnace and was never capped when the system converted to gas or electric. An open furnace flue is a code violation in Westchester County and can pull a neighbour’s exhaust into your stack on attached blocks. We inspect both flues with a camera, cap or decommission the orphaned one properly, and install a liner only in the flue that needs it. Call (914) 603-1360 for a free inspection - we’ll show you exactly what yours requires.
The most common reason is a deteriorated clay tile liner with cracked or offset joints that leak combustion gases, which Westchester home inspectors flag immediately. The second most common is an uncapped or improperly decommissioned furnace flue in a two-flue stack, a code issue under Town of Greenburgh regulations. Both are fixable. We document the condition with camera photos, explain the repair in plain English, and complete most corrections before your closing timeline. Estimates are free - call (914) 603-1360.
Yes, in most cases. If the exterior masonry is structurally sound - no significant leaning, major brick spalling, or foundation failure - we install a stainless or flexible liner inside the existing flue without demolition. We’ve relined Hartsdale chimneys built in 1923, 1936, 1941. The key is a thorough Level 2 inspection to confirm the shell can support the new system. When the crown or upper courses are failed, we do a partial rebuild from the roof up and line the restored flue. Call (914) 603-1360 and we’ll assess yours.
First-degree creosote is flaky, dry, and brushes off easily - what you’d find after a season of hot, dry fires with seasoned hardwood. Third-degree creosote is glossy, tar-like, and hardened to the flue surface; it requires chemical treatment or rotary removal and is common in Hartsdale chimneys where homeowners burn unseasoned wood or smolder fires for long periods. A Level 2 camera inspection shows the difference clearly. We show you the footage and explain whether a standard sweep will handle it or if the glazed layer requires more aggressive treatment before relining. Call (914) 603-1360 to schedule.
It often does, but not always by itself. A properly sized stainless liner reduces the flue volume to match your fireplace opening, which increases draft velocity and reduces smoke spillage into the room. In Hartsdale’s tall, unlined 1920s chimneys, this correction alone solves many smoking problems. However, if the chimney is externally located on a one-story wing, or if surrounding trees or buildings create wind pressure issues, the liner may need to be paired with a proper-height termination cap or smoke chamber modification. We diagnose the full system before recommending anything. Call (914) 603-1360 for an exact assessment.
