Our Chimney Repair team knows Old Greenwich’s housing stock inside out. The pre-war colonials and Tudors that define this neighborhood weren’t built for salt-laden coastal air, and their chimneys show it faster than almost anywhere else in Fairfield County.
Why Premier Chimney Cleaning Connecticut Is Old Greenwich’s Preferred Chimney Repair Company
Eight years, one specialty. That’s the difference. Anthony Perez, our owner, leads every job personally — not a subcontractor, not a seasonal hire. When you call us for your Old Greenwich home, you get the person whose name is on the business and whose reputation is tied to every brick we touch.
800+ homeowners have reviewed us at a 4.7-star average. That volume matters. It means we’ve seen the specific failure patterns that Old Greenwich chimneys develop — the salt-chewed mortar, the rusted dampers, the spalled crowns — and we’ve fixed them hundreds of times.
We’re on the road daily from Bridgeport through Riverside, Cos Cob, and into Old Greenwich. Response time to the 06870 area is typically same-day or next-day for standard repairs, and we carry the materials to complete most repointing and cap jobs in a single trip. No waiting on parts, no second appointment.
From annual sweep to full rebuild, we handle the complete chimney lifecycle. Old Greenwich homeowners don’t need to hire a separate contractor when a small crack becomes a structural problem — we scale with the job.
Our Chimney Repair Services in Old Greenwich
Mortar Repointing
Old Greenwich’s pre-war brick chimneys, baked by salt-laden coastal air from nearby Long Island Sound, experience mortar joint decay at nearly double the rate of inland Connecticut chimneys, making annual inspections critical. We grind out deteriorated joints to proper depth and repoint with color-matched, high-compressive-strength mortar formulated for freeze-thaw resistance. On a home near Sound Beach Avenue last spring, we repointed a 1920s chimney where the original mortar had turned to sand — the homeowner had noticed powdery residue on the patio below, a classic efflorescence sign of salt intrusion.
Spalling Brick Repair
Spalling — when brick faces flake off from freeze-thaw pressure — is epidemic in Old Greenwich’s village core. Salt-saturated mortar absorbs more water here than inland, and every winter cycle pops another layer of brick. We remove spalled units, install matching replacements, and address the underlying moisture source. For severe cases, we rebuild chimney sections using materials rated for coastal exposure. On a Tudor revival home in the village core, we replaced a rusted-out cast-iron damper and installed a DuraFlex stainless steel liner after discovering the original clay tiles were spalling from salt intrusion. The homeowner now schedules annual inspections to catch the accelerated corrosion before it compromises the flue.
Chimney Waterproofing
Waterproofing isn’t optional in 06870 — it’s structural preservation. We apply vapor-permeable sealers that let the chimney breathe while blocking liquid water and salt spray. This is especially critical on chimneys serving oil furnaces, where shared flue configurations already stress the masonry. Our waterproofing jobs near Binney Park and the inland blocks typically follow repointing, sealing the envelope after we’ve restored the mortar joints.
Flashing Repair
Step flashing and counterflashing at the roof-to-chimney intersection fail predictably in Old Greenwich’s coastal climate. Galvanized steel rusts through; aluminum corrodes at the salt line. We fabricate custom flashing from copper or lead-coated copper, materials that outlast the coastal air. Every flashing repair includes inspection of the underlying roof deck — water that gets past flashing often rots sheathing before it shows inside.

Trusted Brands We Service in Old Greenwich
We don’t use hardware-store substitutes. For liner installations, we specify DuraFlex and Olympia Chimney stainless steel systems — the same products chimney professionals specify nationwide. For crown repair and resurfacing, we use HeatShield cerfractory sealant, formulated to withstand thermal cycling and salt exposure. Our cap inventory includes Gelco stainless models, which we keep in stock for Old Greenwich’s accelerated replacement schedule. Technicians working Old Greenwich routinely find that chimney caps and steel dampers on waterfront-adjacent homes have rusted through in as little as five to seven years — half the lifespan of the same components on comparable homes in Stamford or Norwalk inland — making stainless-steel cap upgrades a near-standard recommendation on nearly every inspection here. That local pattern means we carry more stainless inventory and can often replace a rusted cap same-day.
Common Chimney Repair Problems We See in Old Greenwich Homes
- Salt spray from Long Island Sound saturates mortar joints, causing spalling and efflorescence that requires tuckpointing or full chimney rebuilds in as little as 7 years. The homes on Shore Road and the village core blocks feel this first.
- Unlined or clay-tile-lined chimneys in pre-war homes crack during freeze-thaw cycles, creating dangerous gas leaks when shared with oil furnaces. This configuration is common in the 1930s–1950s capes and ranches on Old Greenwich’s inland streets.
- Cast-iron dampers rust through completely from coastal humidity, sometimes jamming open (wasting heat) or closed (creating smoke backup). We replace these with stainless or integrated top-sealing dampers.
- Crown cracks let water penetrate directly to the flue, accelerating liner deterioration. Crown rebuilds with proper overhang and drip edge are standard on our Old Greenwich inspections.

We Also Serve Cities Near Old Greenwich
We work throughout the Greenwich–Stamford corridor: Riverside (just across the Mianus River), Cos Cob, Stamford inland, and the broader Greenwich town limits.

Our Bridgeport base keeps us mobile across all these markets.

FAQs — Chimney Repair in Old Greenwich
Salt-laden air from Long Island Sound accelerates mortar decomposition here by nearly double the inland rate. The sodium chloride crystals expand in freeze-thaw cycles, fracturing the joint from within. We repoint with Type N or Type O mortar modified for coastal exposure, then recommend waterproofing to slow recurrence. Call (833) 719-7193 for an inspection — estimates are free.
Unfortunately, yes. Technicians working Old Greenwich routinely find that chimney caps and steel dampers on waterfront-adjacent homes have rusted through in as little as five to seven years — half the lifespan of the same components on comparable homes in Stamford or Norwalk inland — making stainless-steel cap upgrades a near-standard recommendation on nearly every inspection here. We replace failed caps with Gelco stainless models and can usually do it same-day. Call (833) 719-7193 to schedule.
At minimum, a stainless steel liner installation (we use DuraFlex or Olympia Chimney systems) and a thorough inspection of the existing masonry for salt damage. Unlined chimneys in Old Greenwich’s pre-war housing stock are especially vulnerable to the salt-moisture cycle, and many also show cracked clay tiles if they were lined later. Shared flue configurations with oil furnaces create additional draft hazards. Call (833) 719-7193 — we’ll camera the flue and give you a specific scope.
Annually, without exception. The accelerated corrosion from coastal salt means damage progresses faster here than NFPA guidelines assume for generic climates. We recommend fall inspection before heating season, with a mid-winter check if you burn heavily. Call (833) 719-7193 to get on the schedule.
Yes — flashing repair is one of our most common Old Greenwich calls. We remove corroded step and counterflashing, inspect the roof deck for hidden rot, and install custom-fabricated copper or lead-coated copper that outlasts coastal conditions. Most flashing jobs complete in one day. Call (833) 719-7193 for a free estimate.
