We’re Sterling Chimney Cleaning Yonkers, and our Chimney Repair team makes the trip down from Westchester to Greenwich regularly.

Our Chimney Repair Services in Greenwich
Mortar Repointing
Greenwich’s waterfront homes in Old Greenwich and Cos Cob see mortar joints deteriorate faster than inland properties. The salt-laden air off Long Island Sound penetrates masonry, and inland freeze-thaw cycles widen the damage through winter. We grind out failed joints to proper depth and repoint with limestone-rich mortar matched to your existing masonry—critical for the Tudor Revival and Georgian estates built between 1890 and 1950 that dominate Greenwich’s housing stock. A typical repointing job on a standard two-flue chimney in Greenwich runs $1,200–$2,800.
Spalling Brick Repair
Spalling—where brick faces flake and crumble from moisture intrusion—is epidemic on Greenwich chimneys that lack proper crowns or caps. We see it worst on Back Country estates where deferred maintenance meets heavy coastal weather. Our process removes damaged brick, assesses the underlying structure, and rebuilds with matching materials. For severe cases on estate homes with multiple affected chimneys, we’ll coordinate full-property scheduling to minimize disruption. Spalling repair in Greenwich typically ranges $800–$2,200 per chimney depending on height and accessibility.
Chimney Waterproofing
Waterproofing is non-negotiable for Greenwich’s masonry chimneys. We apply vapor-permeable sealants that block liquid water while letting trapped moisture escape—essential for chimneys that endure Connecticut’s wet springs and freeze-thaw winters. On a recent job, we serviced a 1920s Tudor Revival off John Street in Old Greenwich where salt-spray from the Sound had spalled the crown bricks and corroded the copper flashing. Our crew repointed the stack with a limestone-rich mortar, installed a DuraFlex stainless liner to meet NFPA 211, and waterproofed the entire chimney—all in one trip, as the owner had flown in for the weekend. Full waterproofing with crown repair runs $1,500–$3,200 in Greenwich.
Flashing Repair
Chimney flashing—the metal seal where your chimney meets the roof—is a common failure point in Greenwich, especially on older homes with original copper or galvanized steel that’s corroded past service. We fabricate and install custom flashing using materials selected for your specific roof pitch and exposure. For the heavy snow loads and ice damming common in Back Country’s higher elevations, we favor stepped flashing with ice-and-water shield integration. Flashing repair or replacement in Greenwich typically costs $650–$1,800.

Trusted Brands We Service in Greenwich
We use HeatShield for cerfractory flue resurfacing when clay tile liners show minor cracking but don’t need full replacement—common on Greenwich’s 1920s–1950s chimneys with original terra cotta. For stainless steel liner installations, we spec Olympia Chimney and Famco components, both stocked for fast turnaround so we’re not waiting on parts while your flue sits open. Gelco caps and accessories round out our standard inventory. These aren’t whatever’s cheapest; they’re what Gary specifies based on 11 years, one specialty, and jobs that have to last through Greenwich’s coastal winters.
Common Chimney Repair Problems We See in Greenwich Homes
- Multi-fireplace neglect on Back Country estates. In Greenwich’s Back Country, it’s common for a single estate to have eight or more fireplaces, many in dormant servant quarters or libraries, requiring a full-estate scope that contrasts with neighboring Stamford’s single-flue calls. Large estate owners often skip annual inspections on half their fireplaces, letting raccoons nest in unused flues; when they fire them up in fall, heavy debris and creosote cause chimney fires.
- Accelerated waterfront deterioration. Mortar joints in waterfront homes near Cos Cob deteriorate twice as fast from salt-laden air, yet owners delay repointing until structural cracks widen. By then, water has penetrated the wythe and freeze-thaw damage compounds the repair scope.
- Failed fireplace screen inserts on oversized masonry. Heavy screen-inserts for oversized masonry fireplaces (common in Gilded Age ballrooms) fail without proper spring supports, leaving the flue exposed and unsealed. We fabricate proper supports or spec replacement inserts that won’t sag or gap.
- Original clay liners past code compliance. Greenwich’s housing stock skews heavily toward large Colonial Revival, Tudor Revival, and Georgian-style estates built between roughly 1890 and 1950, many with original unlined or deteriorated clay-tile-lined masonry chimneys that predate modern NFPA 211 relining requirements. Secondary fireplaces in servant quarters, libraries, and master suites on these properties are often left dormant for years, accelerating glaze creosote buildup and animal intrusion when owners begin using them again.

FAQs — Chimney Repair in Greenwich
Because the flues you can’t see from the firebox are often the worst. Dormant second-floor and servant-quarter fireplaces in Greenwich’s Back Country estates accumulate glaze creosote and moisture damage for years without any heat cycling to dry them out. Gary inspects with a camera every flue, every time—what looks intact from below can show shattered clay tile or gaps between flue sections three feet up. Call (844) 660-6590 for a full-estate inspection scope.
Every 15–25 years for standard inland exposure, but every 10–15 years if you’re within a mile of Long Island Sound in Old Greenwich or Cos Cob. The salt-laden coastal air accelerates mortar joint deterioration and spalling on exposed masonry chimneys, exploiting micro-cracks that inland freeze-thaw alone wouldn’t worsen as quickly. Annual inspection lets us catch early degradation before repointing becomes rebuild. Call (844) 660-6590 to schedule—estimates are free.
Yes. Chimney swifts and raccoons colonize unused flues on the large wooded Back Country 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 clear nests, install proper caps with animal-proof screening, and then proceed with repair. Wildlife exclusion with cap installation typically adds $400–$900 to the scope. Call (844) 660-6590 to discuss your property’s situation.
Because creosote doesn’t need active fires to form—temperature differentials and humid air draw moisture through the flue, leaching existing deposits and producing that sharp, acrid smell. In Greenwich’s dormant estate fireplaces, years of accumulated glaze plus summer humidity create concentrated odor that hits when you open the damper in October. A proper sweep removes the source, and we inspect for cracks that let household air pull down the flue. Call (844) 660-6590 to book a sweep and inspection before you need the fireplace.
Copper or lead-coated copper for longevity, with stepped installation and ice-and-water shield backing for the heavy snow loads and ice damming common in northern Greenwich and Back Country elevations. Standard aluminum flashing degrades faster under freeze-thaw cycling and salt exposure. We fabricate custom pieces on-site for your specific roof-to-chimney junction. Flashing replacement in Greenwich runs $650–$1,800 depending on roof complexity. Call (844) 660-6590 for material recommendations specific to your home’s exposure.
