We’ve been crossing the Connecticut border from Yonkers to work in Greenwich for years. Gary Murphy, our owner and lead technician, knows the difference between a 1990s Colonial in Riverside and a 1920s Tudor Revival off Round Hill Road — and he knows that each demands a different approach to liner sizing, insulation, and draft calculation. Our Chimney Liner & Rebuild team doesn’t dispatch unfamiliar crews; Gary leads every job himself.
Why Sterling Chimney Cleaning Yonkers Is Greenwich’s Preferred Chimney Liner & Rebuild Company
Over 1,100 homeowners have trusted us with their chimneys, and our 1,142 verified reviews averaging 4.7 stars reflect what happens when the same technician who quotes the job climbs the ladder to do it. In Greenwich, that consistency matters more than usual — you’re not handing keys to a stranger who’ll subcontract the work to someone you’ve never met.
We understand Greenwich’s housing stock because we’ve worked inside it. The estate homes north of the Merritt, the waterfront properties along Shore Road in Old Greenwich, the converted carriage houses near Putnam Avenue — each carries distinct chimney challenges that only show up after you’ve opened the cleanout door and looked up the flue. Gary’s 11 years of chimney-only work means he’s seen the patterns: which neighborhoods have unlined brick flues from the 1890s, which developments used inferior clay tile in the 1960s building boom, where the salt air hits hardest.
Our response time to Greenwich averages same-day or next-day for urgent calls — liner collapses, blocked flues, or carbon monoxide backdraft situations. For scheduled inspections and quotes, we’re typically available within 48 hours. We don’t charge travel fees for Greenwich calls; the 20-minute drive from our Yonkers base is built into our standard pricing.
Our Chimney Liner & Rebuild Services in Greenwich
Stainless Steel Liner Installation
For most Greenwich homes with deteriorated clay tile or unlined masonry chimneys, we install rigid or flexible 316Ti stainless steel liners fabricated by DuraFlex or Olympia Chimney. These carry a lifetime warranty when properly installed with insulated tops — critical in Greenwich, where the temperature differential between your heated flue gases and cold masonry can create condensation that destroys lesser materials. On a recent job near Round Hill Road in the Back Country, our crew lined seven dormant flues in a 1920s Tudor Revival using DuraFlex stainless steel. Three had been colonized by raccoons and required wildlife exclusion before we could begin; two original clay liners were collapsing, so we tore out the old tile and installed seamless flexible liners with insulated tops.
Flexible Liner Systems
Tudor Revival and Georgian chimneys in Greenwich’s older neighborhoods often have offset flues, corbelled smoke chambers, or tight cleanout bends that make rigid stainless steel impossible to feed through. Flexible liners from DuraFlex navigate these obstructions while maintaining the same 316Ti alloy specification. We see this constantly in the 06830 zip — homes built between 1910 and 1940 with multiple fireplace flues that shift direction somewhere above the smoke shelf. Flexible installation costs typically run 15–20% less than rigid where offsets are present, since we avoid the masonry demolition otherwise required to straighten the flue path.
Liner Replacement & Repair
Not every damaged liner needs full replacement. For clay tile chimneys with isolated cracks or minor spalling, we apply HeatShield cerfractory sealant — a refractory compound that restores the flue’s integrity without tearing out the original structure. This saves Greenwich homeowners $1,500–$3,000 versus full relining when the damage is localized. However, we’re direct about when HeatShield won’t work: multiple cracked tiles, shifted flue joints, or glazed creosote bonding failure all indicate replacement, not repair. Gary makes that call on-site, not from a desk in Yonkers.
Partial Chimney Rebuild
The salt-laden coastal air from Long Island Sound accelerates mortar joint deterioration on exposed chimneys in Old Greenwich and Cos Cob. Once spalling begins, freeze-thaw cycles through Connecticut winters exploit those micro-cracks, dislodging clay tiles and weakening the structural shell. Our partial rebuilds address the upper courses, crown, and flue surround without dismantling the entire chimney — typically $4,500–$8,500 for a two-story exposure in the 06870-adjacent waterfront zones. We match existing brick and mortar where possible, and we always inspect the interior flue before rebuilding the exterior; there’s no point in a beautiful new crown over a collapsed liner.
Full Chimney Rebuild
When spalling, shifting foundation, or long-neglected water intrusion has compromised the chimney’s structural integrity, we dismantle and rebuild from the roofline up — or from the ground up when the foundation has failed. Full rebuilds in Greenwich’s Back Country estates run $12,000–$25,000 depending on height, scaffolding complexity, and whether we’re restoring multiple flues. These jobs require permits from the Greenwich Building Department, and we handle that paperwork as part of our scope. From your first sweep to a full liner rebuild, you stay with one operator.

Trusted Brands We Service in Greenwich
We stock DuraFlex flexible and rigid liners, HeatShield cerfractory resurfacing compound, and Gelco stainless steel chimney caps because these are the materials that hold up in Greenwich’s conditions — not the cheapest options, but the ones that don’t fail after three coastal winters. For crown repairs and custom flashing, we source from Famco and Olympia Chimney. Keeping inventory on our Yonkers trucks means we’re not waiting on FedEx to start your job; most Greenwich liner installations begin the day after you approve the estimate. We choose materials based on what your specific chimney needs, not what we happen to have overstocked.
Common Chimney Liner & Rebuild Problems We See in Greenwich Homes
- Salt-air mortar destruction on waterfront chimneys. The chimneys facing Long Island Sound in Old Greenwich and Cos Cob absorb chloride-laden moisture that crystallizes in mortar joints, causing surface spalling and structural loosening. We inspect these annually — the damage accelerates dramatically after year three without maintenance.
- Freeze-thaw tile collapse after coastal micro-cracking. Once salt corrosion opens hairline fractures in mortar or clay tile, winter water infiltration and expansion breaks pieces loose. Those fragments tumble down the flue and create blockages that send smoke into living spaces — a pattern we diagnose every March after harsh Greenwich winters.
- Multi-flue estate complexity with dormant secondary fireplaces. Greenwich’s Back Country estates frequently have six or more fireplaces per property, many with original unlined clay tile flues from the 1920s that require custom-fabricated stainless steel liners to meet modern NFPA 211 standards — a complexity seldom seen in single-chimney homes elsewhere in Fairfield County. Quoting these jobs demands flue-by-flue inspection, not a per-chimney flat rate.
- Wildlife obstruction in unused Back Country flues. Chimney swifts and raccoons colonize unused flues on large wooded estates at a notably high rate. Estate owners who split time between Greenwich and other residences often return in fall to chimneys that have been occupied all summer, requiring wildlife exclusion and heavy debris clearing before any sweep or inspection can begin. We handle the exclusion; we don’t subcontract to wildlife services who don’t understand chimney construction.

FAQs — Chimney Liner & Rebuild in Greenwich
Yes — cracked clay tile liners violate NFPA 211 safety standards and must be repaired or replaced before regular use. In Greenwich’s Back Country estates, we often find original 1920s clay tile that has shifted, spalled, or cracked due to decades of thermal cycling and freeze-thaw stress. Gary Murphy inspects each flue with a video camera to determine whether HeatShield resurfacing can seal isolated damage, or whether full stainless steel relining is required. Call (844) 660-6590 to schedule an inspection — estimates are free, and we won’t recommend work that isn’t necessary.
Salt-laden coastal air accelerates mortar joint deterioration and spalling on exposed masonry chimneys, a problem most acute in waterfront Cos Cob and Old Greenwich neighborhoods. The chloride ions penetrate porous brick and mortar, then crystallize and expand as humidity fluctuates, causing surface flaking and structural weakening. We inspect these chimneys annually — the damage progresses from cosmetic to structural faster than inland properties. If you’re in the 06807 zone or along Shore Road, your chimney needs more frequent monitoring than Back Country equivalents. Call (844) 660-6590 for a coastal-condition inspection.
Yes — we specialize in multi-flue estate work, and we’ve lined as many as seven flues in a single Greenwich property. Back Country estates frequently have six or more fireplaces per property, many with original unlined clay tile flues from the 1920s that require custom-fabricated stainless steel liners. We stage the work to minimize disruption, typically completing 2–3 flues per day depending on access and condition. Gary Murphy manages the full scope personally — you won’t get a rotating crew of strangers. Call (844) 660-6590 for estate-specific pricing.
For unlined 1930s Tudor Revival chimneys in Greenwich, we typically specify 316Ti stainless steel in a flexible configuration, with an insulated top and proper connector to your appliance. The offset flues common in this era’s construction make rigid liners impractical, and the unlined masonry requires insulation to meet modern clearance-to-combustible standards. We use DuraFlex for these installations — the alloy specification holds up to the acidic condensates produced by modern, efficient appliances venting into large, cold masonry flues. Call (844) 660-6590 and Gary will size your specific flue on-site.
Yes — the Greenwich Building Department requires permits for all chimney liner installations and rebuilds, with inspections typically scheduled at rough-in and final completion. We pull these permits as part of our standard workflow; you don’t need to visit Town Hall. The process adds 3–5 business days to project start, but it ensures your installation meets Connecticut state code and your homeowner’s insurance requirements. For full rebuilds in historic districts, additional HDC review may apply. Call (844) 660-6590 and we’ll confirm the permit timeline for your specific property.
