We’ve been driving to Greenwich since 1984. We know the difference between a quick sweep on a modern gas insert in Riverside and a six-flue inspection on a back-country estate north of the Merritt Parkway. The latter takes time, specialized camera equipment, and a technician who understands early-20th-century masonry flues that may have been partially converted, abandoned, or forgotten entirely. That’s the work our Chimney Cleaning & Sweep team trains for.

Our Chimney Cleaning & Sweep Services in Greenwich
Level 1 Inspection
A Level 1 inspection in Greenwich covers the readily accessible portions of your chimney structure and flue. For a typical colonial on Tomac Avenue or a waterfront home in Old Greenwich with a single active fireplace, this is often sufficient for annual maintenance. We examine the firebox, damper, and visible flue lining for creosote buildup, obstructions, and structural soundness. The inspection includes a basic sweep if needed, and we finish with photos and a written verdict you can file with your insurance or property manager.
Level 2 Inspection
Level 2 inspections are what we perform most often in Greenwich - and for good reason. When a property has multiple fireplaces, dormant flues, or any change to the system (a new gas insert, a relining, a weather event), NFPA 211 requires a camera inspection of the entire flue interior. We recently cleaned a six-flue stack on a 1920s Tudor estate in Cos Cob, where the homeowner had no idea the dormant wood-burning flue was packed with raccoon nesting and a decade of creosote glaze - our Level 2 inspection also revealed a collapsed clay tile section that we relined with a HeatShield cast-in-place system. The camera doesn’t lie, and the photos don’t disappear: you see what we see, and we explain what it means in plain English.
Creosote Removal
Greenwich’s back-country estates routinely have four to six fireplaces per property, many with original early-20th-century masonry flues partially converted to gas inserts, leaving dormant wood-burning flues uncleaned for years - a scenario rarely seen in neighboring Fairfield County towns. These abandoned flues accumulate glazed creosote, a hardened, tar-like deposit that standard brushing won’t remove. Glazed creosote is combustible. It reduces flue diameter. And it’s often invisible until a camera goes up. We remove it with mechanical whipping systems and, when necessary, chemical treatments that break the glaze so it can be safely extracted. This is not a quick-pass job. It takes the time it takes.
Soot Removal & Annual Sweep
An annual sweep in Greenwich is straightforward for an active, well-maintained fireplace: we remove soot and light creosote, check for obstructions, and certify the flue for another year of use. But “annual” assumes the fireplace is actually being used and inspected. On many Round Hill Road and North Street properties, household staff or property managers rotate through maintenance schedules and the dormant flues get skipped entirely. We recommend a formal rotation - every flue, every year, documented - because a flue that hasn’t drawn smoke in five years can still draw moisture, nesting animals, and structural decay.

Trusted Brands We Service in Greenwich
We work exclusively with professional-grade materials - no builder-grade substitutes that fail in five years. For relining and restoration in Greenwich’s historic homes, we specify HeatShield for cast-in-place flue resurfacing and DuraFlex for stainless steel liner installations. These are the products we trust on 100-year-old masonry that can’t tolerate another failed repair. We stock common fittings and accessories from Famco and Copperfield, which means most Greenwich jobs don’t wait on parts. When you’re managing a property with six fireplaces, you don’t have time for supply-chain delays.
Common Chimney Cleaning & Sweep Problems We See in Greenwich Homes
- Decade-old creosote glaze in dormant flues. Property managers and household staff focus on active fireplaces. The dormant wood-burning flue on the third floor hasn’t been opened since 2008. We open it and find glazed creosote an inch thick, reducing the flue to a fire hazard no one knew existed.
- Spalling mortar joints on tall, exposed stacks. Greenwich’s Long Island Sound shoreline position moderates deep freezes, but persistent nor’easter moisture combined with repeated freeze-thaw cycles through winter aggressively erodes mortar joints on exposed exterior chimneys - a particular problem on the tall, multi-story stacks common on estate properties where repairs require staging or lift equipment.
- Hidden flue tile efflorescence and moisture intrusion. The wet climate accelerates flue tile efflorescence and interior moisture intrusion in infrequently used fireplaces. White mineral deposits on the flue lining indicate water penetration that will eventually destroy the tile from the inside out.
- Active wildlife nesting in abandoned flues. Chimney swifts, raccoons, and squirrels colonize uncapped or deteriorated flues, particularly on properties where maintenance schedules skip the dormant chimneys. The obstruction is complete, and the animal damage to the flue lining often extends well below the nest.

A three-story estate chimney off Round Hill Road requires taller ladders, additional safety rigging, and more time per flue than a single-story ranch in Riverside. Dormant flues with heavy creosote or wildlife obstructions also add time. We provide upfront pricing before any work begins - the number on the estimate is the number on the invoice. Estimates are free. Call (855) 950-3861.
Standing offers: $50 off any repair over $250; free second opinion on any written estimate; $89 seasonal tune-up; permanent 5% senior and veteran discount.

FAQs - Chimney Cleaning & Sweep in Greenwich
Every flue should be inspected annually, whether active or dormant. In Greenwich’s estate properties, we recommend a formal rotation schedule that documents each flue by location, last service date, and condition - because dormant flues accumulate creosote, moisture damage, and wildlife nesting that no one discovers until there’s a problem. Call (855) 950-3861 and we’ll build a schedule that fits your property.
Yes - Level 2 camera inspections are standard for any multi-flue or multi-story stack, which describes most back-country estate chimneys in Greenwich. Our camera systems reach the full height of these tall flues, and the video documentation becomes part of your property record. You’ll see exactly what we see.
We specify HeatShield for cast-in-place flue resurfacing in historic masonry chimneys where preserving the original structure matters, and DuraFlex stainless steel liners where a full replacement is required. Both are professional-grade products we trust on century-old construction. We do not use builder-grade substitutes.
Yes, and we do so regularly in Greenwich. A flue dormant for 20 years requires a Level 2 inspection first - we camera the full length, assess for collapsed tile, mortar decay, and wildlife obstruction, then clean and repair as needed. The flue is often salvageable. Occasionally it is not. We tell you which before any work proceeds.
Yes. Chimney swifts are protected under federal law, so removal requires specific timing and methods. We handle the extraction legally and humanely, then install proper screening to prevent re-entry. If swifts have damaged the flue lining, we document it with photos and recommend repair options. Call (855) 950-3861 for scheduling - swift season has narrow windows.
