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.

AfterGelco Chimney Cleaning in Greenwich, CT | Top Hat Chimney
We provide independent Gelco Chimney Cleaning & Sweep - Greenwich, cap, and damper service across Greenwich, CT, and the thing that sets our work apart here is simple: we know how Gelco hardware fails on Gold Coast-era multi-flue stacks and in the salt air along Old Greenwich and Riverside. We’re not manufacturer-affiliated or authorized, just a local crew that has opened hundreds of Gelco caps and dampers across Fairfield County and knows exactly what to look for before a small problem becomes a flue full of creosote or a damper that won’t seal. If you’re in Greenwich and your Gelco equipment needs attention, call (475) 242-5865 and we’ll give you a straight answer.
Why Greenwich Residents Choose Us for Gelco Service
Gelco makes solid chimney caps and dampers, but no cap survives forever, especially not in Greenwich. Our familiarity with their product lines extends to every model family you’re likely to find on a Greenwich rooftop: 6×6 square top mounts, extended-height 8x8s, multi-flue 24x24s, and stainless top-mount dampers. Wendell Pike, our owner, has spent the better part of two decades running crews through chimneys all across Fairfield County, including plenty of afternoons on rooftops near Stamford’s Shippan Point neighborhood. He learned building systems and ventilation at Palomar College before deciding soot and flue tile suited him better than a desk. That background means we don’t guess at Gelco hardware: we measure, we inspect, and we tell you plainly what needs doing and what can wait.
We’re locally owned and owner-operated, with a published address and license number. The person who answers the phone may well be Wendell himself, and the sweep who shows up at your door will be background-checked and in uniform. We also stock the Gelco caps, dampers, and replacement hardware Greenwich homeowners ask for most often, so the turnaround on common repairs is measured in days, not weeks. And as an independent Gelco sales & service provider, we carry genuine Gelco components when dimensions and mounting anchors are still sound, and we’ll say so when an upgrade makes better sense for your situation.
Common Gelco Chimney Cleaning Problems We Solve in Greenwich
Here are the Gelco-specific failures we see most often in Greenwich, and why they happen here more than almost anywhere else in Fairfield County.
- Corroded seams and mounting brackets on galvanized caps. Gelco 24-gauge galvanized caps typically corrode at the welded seams and mounting brackets within 4 to 6 years in Old Greenwich and Riverside. The salt-laden air blowing off Long Island Sound attacks the weld points first, and we frequently find the wind brace attachment points failing before the cap body itself shows rust. When we see pitting or weld-spot failure, we replace rather than patch.
- Seized or stiff top-mount damper pivots. On older Greenwich estates, Gelco top-mount dampers accumulate creosote fines and mortar dust in the pivot assembly. After a few seasons, the damper becomes impossible to close fully during shoulder seasons, which means heated air escapes up the flue all spring and fall. We disassemble, clean, and lubricate the pivot assembly, then test the seal with the damper closed.
- Wind-driven rain bypass on multi-flue caps. Backcountry chimney stacks with three or four uncoupled flues are a Greenwich specialty. When a Gelco multi-flue cap’s drip edge doesn’t extend at least 2 inches beyond the outer flue liner, wind-driven rain gets past the cap and soaks the flue interior. We correct the mis-spec rather than just replacing the cap with the same wrong size.
- Torn stainless mesh at cap corners. Mid-country Greenwich neighborhoods with mature oak canopy over the roof see regular raccoon and squirrel attempts at chimney entry. Gelco stainless steel mesh on custom caps tears at the corners where animals pry and claw, and once the mesh is compromised, the cap stops doing its job. We replace the mesh and reinforce the corners when the cap body is still sound.
- Flue combinations that overload a single Gelco cap. In coastal Greenwich colonials and Tudors from the 1920s through 1960s, a single original flue frequently serves both a wood-burning fireplace and a converted oil or gas appliance. That combination produces heavy creosote buildup and draft problems, and it means the cap and damper have to work harder than they were ever designed to. We clean the full flue and camera-inspect the appliance connection before reinstalling or replacing Gelco hardware.
Gelco Service in Greenwich: What Local Conditions Mean for Your Equipment
North of the Merritt Parkway in Greenwich, a single exterior chimney stack often hides three or four separate but poorly separated flues sharing crumbling clay tile. These Gold Coast-era estates, most built between the 1890s and 1940s, routinely contain four to eight individual wood-burning fireplaces under one roof, each with its own aging masonry flue. A single service call here can mean cleaning and camera-inspecting more flues than a sweep would handle in an entire day elsewhere in Fairfield County. When we cap or clean one Gelco flue on those estates, we camera-inspect every adjacent flue so a crack or offset in an uncoupled neighbor doesn’t keep pushing combustion gases into living spaces homeowners assume are served by entirely different chimneys. That’s the real risk on a backcountry estate: not the flue you’re looking at, but the one next to it that hasn’t been touched since the Coolidge administration.
Gelco Models & Products We Service in Greenwich
We service the full Gelco product range you’re likely to see on Greenwich roofs, including the Gelco 6×6 Square Top Mount Chimney Cap, the Extended Height 8×8 Chimney Cap, the Multi-Flue 24×24 Chimney Cap, and the Stainless Steel Top-Mount Damper. Our parts approach is straightforward: we install genuine Gelco caps, dampers, and replacement hardware when dimensions and mounting anchors are still intact. For corrosive coastal locations in Old Greenwich and Riverside, we recommend upgrading to Gelco’s stainless steel series or a HeatShield-compatible refractory cap. We stock the most common Gelco cap sizes and damper parts locally, which keeps turnaround fast for Greenwich customers who need work done before burning season. If you’re not sure which model you have, we’ll identify it on site and show you the camera footage before any recommendation is made.
Gelco Service Pricing in Greenwich
Here’s what you can expect to pay for Gelco chimney cleaning and cap or damper work in Greenwich.

What drives the cost in Greenwich is the stack itself: steep roof pitches, multi-flue configurations, and rooflines that require staging or a second crew member. That’s why every estimate starts with the flue count and the roof access, and why we deliver upfront pricing before a single tool comes off the truck. The number you hear on the phone is the number on the invoice. Call (475) 242-5865 for a free estimate, and we’ll talk through exactly what your stack needs.

FAQs - Gelco Chimney Cleaning in Greenwich
Gelco galvanized caps typically last 4 to 6 years in the salt-laden air along Greenwich’s Long Island Sound shoreline before the welded seams and mounting brackets show significant corrosion. The wind brace attachment points usually fail first. If you live in Old Greenwich or Riverside and notice rust streaks on your chimney cap, the cap has already started to fail. We recommend upgrading to Gelco’s stainless steel series or a compatible refractory cap in those corrosive coastal zones. Call (475) 242-5865 for a cap inspection and we’ll tell you what condition yours is in.
Yes, but the sizing has to be exact. Gelco multi-flue caps need a drip edge that extends at least 2 inches beyond the outer flue liner on every side. On backcountry Greenwich stacks with three or four uncoupled flues at different heights, that often means custom fabrication rather than an off-the-shelf 24×24. We measure every flue, photograph the stack, and order the cap to the actual dimensions instead of guessing from the ground. A mis-specified cap lets wind-driven rain bypass the cap entirely, which is worse than no cap at all.
Creosote fines and mortar dust accumulate in the pivot assembly and along the damper track, especially on older Greenwich estates where the flue was never fully desooted before the damper was installed. The fix is disassembly, cleaning, and re-lubrication of the pivot, followed by a seal test with the damper closed. If the damper plate itself has warped from heat, replacement is the honest call. We’ll show you the pivot on camera before we recommend either path.
We do. Whether your Gelco cap was installed by another chimney company or came with the house, we’ll inspect it, clean it, and tell you honestly whether it needs our Chimney Repair in Greenwich or replacement. We’re an independent Gelco service provider, not a manufacturer-authorized operation, so there’s no bias toward replacing something that still has life in it. If it doesn’t need doing, we’ll be the first ones to tell you.
You need a cap sized to the actual flue dimensions and stack configuration, not a guess based on the number of fireplaces. In Greenwich’s older colonials and Tudors, a single exterior stack often contains two or more separate flues at different heights, and each flue needs its own cap or a properly oversized multi-flue cap with the correct drip edge. We measure on the roof and give you a specific recommendation before any cap is ordered. For an exact quote on your stack, call (475) 242-5865 and we’ll walk through what you have.
