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.

AfterFast, Reliable Chimney Cleaning & Sweep Across Greenwich
A chimney sweep in Greenwich typically runs $229 to $389 for a standard cleaning with a Level 1 inspection. That’s the honest range most homes in Cos Cob, Riverside, Old Greenwich, and farther north into backcountry can expect. But Greenwich is not a one-price town, and a quick quote over the phone rarely matches the house standing in front of you. Wendell Pike and his crew at Top Hat Chimney have worked these streets since 1999, and they know the difference between a 1920s Riverside Tudor and a backcountry estate with seven fireplaces. Call (475) 242-5865 and you’ll get a live person, a straight answer, and a firm price before a single tool comes off the truck.
Your flue doesn’t care how the fire looks. It cares how it breathes. And in Greenwich, where salt air eats mortar on Old Greenwich shorelines and 100-year-old clay tile liners hide behind stone facades, it pays to have someone who’s seen it before.
Why Top Hat Chimney Is Greenwich’s Preferred Chimney Cleaning & Sweep Company
Wendell Pike founded Top Hat Chimney in 1999 and has spent over 29 years inside chimneys across Fairfield County. He puts his name and license number on every job, which is more than most national outfits will do after they’ve rotated a franchise van into town last spring. Greenwich homeowners tend to notice that. The crews are background-checked, show up in uniform, and call ahead if a job on Round Hill Road runs longer than expected.
Reviews from Greenwich customers consistently mention two things: the price quoted on the phone is the price on the invoice, and the camera footage speaks for itself. When we clean a chimney, we run a camera through it. You see what we see. If there’s a crack, an offset, or a flue that’s quietly venting into a wall cavity, you’ll have plain-English proof, not a scare tactic. That’s the way it should work. The 90-Day Done Right Promise backs every sweep and repair in writing. If it’s not right, one call brings Wendell himself back, no arguing, no extra invoice.
Our Chimney Cleaning & Sweep Services in Greenwich
Most Greenwich homes need more than a brush through the flue. Between the Gold Coast-era estates north of the Merritt Parkway and the shoreline colonials in Old Greenwich, the housing stock demands a sweep who understands masonry, multiple flues, and what 80-year-old liners actually look like from the inside. Here’s what our Chimney Cleaning & Sweep team handles most often in Greenwich.
Level 1 Inspection
A Level 1 inspection is the standard visual check that accompanies every annual sweep. For a well-maintained chimney with no changes to the appliance or venting system, it’s usually all you need. In Greenwich, where many households burn wood regularly from October through March, we recommend pairing this with your sweep every year. It covers the accessible portions of the flue, damper, firebox, and exterior stack. If you’ve recently moved into an older Greenwich home, this is the minimum starting point before your first fire.
Level 2 Inspection
A Level 2 inspection goes further: camera scanning the entire flue interior, checking the attic and crawlspace portions, and evaluating clearances. This is the inspection Greenwich homeowners need after any real estate transaction, any chimney fire, any change in fuel type, or any major weather event. Given how many Greenwich estates have converted original wood-burning fireplaces to gas inserts over the decades, a Level 2 inspection is often the only way to confirm the original clay tile liner is still sound behind that new insert. We find issues on Level 2 inspections in Greenwich that a visual-only sweep would never catch. The camera footage and a plain-English verdict come with every one.
Creosote Removal
First-degree creosote is a brush job. Third-degree is a glaze. Catch it early. In Greenwich, where unseasoned hardwood and occasional damp shoulder-season burns are common, creosote accumulates faster than homeowners expect. We use mechanical rotary removal for heavier deposits, which is safer and more thorough than scraping for glaze-stage creosote. If you smell a sharp, smoky odor from your fireplace even when it’s cold, or you notice tar-like drips inside the flue, call us before you light another fire. Creosote glaze is the fuel behind most chimney fires, and Greenwich’s older, larger flues give it plenty of surface area to build on.
Soot Removal
Soot is the softer, powdery byproduct of incomplete combustion. It’s less dangerous than creosote glaze but it still restricts draft and can coat your damper, smoke shelf, and firebox with a fine black film. In Greenwich homes with converted gas or oil appliances venting through an original flue, soot can mix with residual creosote and create a sticky compound that’s harder to remove. Our crew uses HEPA-filtered vacuums and drop cloths as standard, so your Greenwich living room doesn’t end up wearing the soot we came to remove.

Trusted Brands We Service in Greenwich
We install and service chimneys, caps, and liner systems from brands we trust: DuraFlex stainless liners, HeatShield sealants, Gelco caps, Olympia Chimney components, Famco, and Copperfield. When a Greenwich backcountry estate needs a reline on a compromised 1920s clay tile flue, we typically recommend a DuraFlex stainless liner for longevity and clean draft. When an Old Greenwich home needs a new chase cover to replace one corroded by salt air, we use Galco or Copperfield products. We keep common parts stocked locally, so we’re not waiting on a shipment from Ohio before we can finish your job.
Common Chimney Cleaning & Sweep Problems We See in Greenwich Homes
- Multi-flue stacks hiding cracked liners. North of the Merritt Parkway, a single exterior chimney stack on a Gold Coast-era estate can conceal three or four separate, uncoupled flues, one per story, that share no internal separation beyond crumbling clay tile. A crack or offset on one flue silently channels combustion gases into adjacent living spaces that homeowners assume are served by entirely different chimneys.
- Salt-eroded mortar joints. In Old Greenwich and Riverside, Long Island Sound air aggressively erodes mortar joints and corrodes metal dampers and chase covers faster than ten miles inland. Visual-only cleanings miss active water entry paths. During freeze-thaw cycles, water in the joints expands, spalls the brick faces, and opens seams for more water.
- Creosote glaze in seldom-used estate flues. Large Greenwich homes often have one or two fireplaces that burn regularly and four more that sit cold for years. Neglected flues still accumulate creosote from the occasional holiday fire, and glaze hardens without regular brushing. By the time someone notices, mechanical removal is the only option.
- Converted inserts hiding compromised liners. Greenwich homes built in the 1920s through 1960s frequently converted original wood-burning fireplaces to gas inserts. The original clay tile liner, which was already marginal, gets called into service for a different fuel type with different draft needs. Brushing alone never verifies whether that liner is still intact behind the insert.

FAQs - Chimney Cleaning & Sweep in Greenwich
Every flue that vents an active fireplace, wood stove, or heating appliance needs an annual sweep and inspection, burn or no burn. In backcountry Greenwich, a single home routinely has four to eight individual wood-burning fireplaces, each with its own flue. If you burn all of them, all of them need cleaning. If only two are used, the unused flues still need an annual inspection because chimneys break in the off-season too, and creosote glaze can harden regardless. We’ll map every flue in your home, not assume one chimney equals one job. Call (475) 242-5865 and we’ll walk your specific house.
Your Old Greenwich chimney is exposed to salt-laden air from Long Island Sound, and that salt air erodes mortar joints even when the fireplace sits cold for years. The mortar is the chimney’s weather barrier, not the brick. When it crumbles, water enters, freezes, and spalls the brick faces. This is true for Old Greenwich and Riverside homes from the 1920s through the 1960s with original soft mortar. Repointing is structural maintenance, not a fire-use issue. If you see white powdery residue on the brick or missing mortar joints, get it addressed before the next freeze-thaw cycle.
Yes, and this is one of the most dangerous misunderstandings we see in Greenwich. North of the Merritt Parkway, a single exterior stack on an estate house often contains three or four separate, uncoupled flues, one per story. They share no internal separation beyond the clay tile. A crack or offset on one flue channels combustion gases into living spaces served by another. This is why we camera-inspect every flue individually, even when the stack looks uniform from the ground. A brush-and-go without camera inspection misses cross-flue gas migration entirely.
A Level 1 inspection is a visual check of the accessible portions of the flue, damper, and firebox, and it’s sufficient for a chimney that hasn’t changed and has no history of problems. A Level 2 inspection includes a full camera scan of the flue interior, attic and crawlspace portions, and clearances to combustibles. For a 1920s Riverside Tudor with an original flue that may serve both a wood-burning fireplace and a converted gas or oil appliance, a Level 2 inspection is what we recommend. It’s the only way to see whether the liner is intact behind the firebox, and it’s required after any property transfer or chimney fire.
Third-degree creosote is a hardened glaze that a regular brush won’t remove. We use mechanical rotary removal: a spinning head with stainless steel chains or blades that breaks the glaze free from the flue walls, followed by a HEPA-filtered vacuum to capture the debris. On older Greenwich chimneys with spalling clay tile, we’re careful not to over-aggress the liner during mechanical removal, and we’ll camera-inspect afterward. If the liner is too compromised, a DuraFlex stainless liner is the standard fix. Call (475) 242-5865 and we’ll give you an honest read on what your flue actually needs.
