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 Cap & Crown Across Pemberwick
A chimney cap and crown in Pemberwick typically runs $240-$680 installed, depending on whether you need a standard single-flue cap, a multi-flue cap for a shared stack, or a full crown rebuild with coating. We get to most Pemberwick homes within one to two business days, and the number you hear on the phone is the number on the invoice. Wendell Pike founded Top Hat Chimney in 1999, and he still answers the phone himself most nights. Call (475) 242-5865 and you’ll talk to a live person, not a call center.
Pemberwick is different from the rest of Greenwich, and your chimney knows it. These are older homes, built tight to the street and to each other, and many still carry the marks of coal heat, oil conversions, and gas retrofits that were done on a budget decades ago. We know what that does to a crown over time because we’ve seen it from the roof of nearly every style of house in this neighborhood. This page is about what actually fails up there, what it costs to fix, and when it can honestly wait.
Why Top Hat Chimney Is Pemberwick’s Preferred Chimney Cap & Crown Company
Ask anyone on your street. Wendell has been working chimneys in Fairfield County since 1999, and in Pemberwick that matters more than in most places. This is a neighborhood of two-families and converted rental units, where one chimney stack often carries two or three appliances from different units. The national chains that advertise in Greenwich don’t send a sweep who understands what a shared flue means for your gas furnace when the neighbor’s old oil burner flue is still open to the rain. Wendell and his crew do.
Every Pemberwick job we complete is backed by the 90-Day Done Right Promise, in writing, on every invoice. If the cap leaks or the crown coating fails within three months, one call brings us back at no charge. We also give you the camera footage from every inspection, along with a plain-English verdict on what needs work now and what can safely wait. Nothing gets recommended without visual evidence you can see for yourself, and we’ll tell you straight when a repair isn’t urgent. That’s how we’ve kept Pemberwick customers coming back for over two decades, and why they hand our number to the neighbor who just bought the two-family down the block.
Our crews arrive in uniform, background-checked, and they give you a real arrival window and call if it slips. Scheduling is coordinated from our Hartford office, but the sweep who shows up at your Pemberwick door knows this neighborhood. He’s parked on Byram Road, he’s navigated the tight alleys off Mill Street, and he’s carried ladders up the narrow side yards between two-families more times than he can count.
Our Chimney Cap & Crown Services in Pemberwick
Cap Installation
A properly installed cap keeps rain, leaves, squirrels, and birds out of your flue, but in Pemberwick the calculus is often more complicated. Many chimneys here carry multiple flues from separate units, and each flue may vent a different appliance at a different temperature. A single-flue cap slapped on the wrong opening can trap moisture in an unused flue or force gas exhaust back toward a neighbor’s living space. We measure each flue, identify which one vents which appliance, and install the right cap for each opening. Typical Pemberwick cap installation runs $240-$380 for a standard stainless single-flue cap.
Cap Replacement
Old caps rust out, screens tear, and the mesh that once kept critters out becomes a clogged mess of leaves and soot. In Pemberwick’s river-valley humidity, galvanized caps from the big-box stores corrode faster than they would a few miles inland. We replace them with stainless models from Copperfield or Olympia Chimney that hold up to coastal Fairfield County moisture. Expect $280-$520 for a replacement, depending on flue size and condition. If you’ve already got an estimate from another company, bring it to us for a free second opinion before you sign anything.
Crown Repair
The crown is the concrete or mortar slab that seals the top of the chimney around the flue openings. On Pemberwick’s century-old masonry chimneys, crown mortar crumbles under repeated freeze-thaw cycles near the Byram River, letting water soak into the flue tile and adjacent party walls. We chip out the failed material, rebuild the crown with a proper overhang and drip edge, and seal it with a flexible crown coating. A straightforward crown repair in Pemberwick runs $350-$680. If the crown is gone but the flue liners are still sound, the repair is straightforward and we’ll have it done in a few hours.
Crown Coating
When a crown is structurally intact but the surface is cracked, porous, or starting to spall, a crown coating buys you years of protection for a fraction of the cost of a rebuild. This is where we lean heavily on our Chimney Cap & Crown work, because Pemberwick’s damp river air makes coatings fail faster if the surface isn’t properly prepared. We use a Gelco crown coat system on brick crowns that stay damp from river-valley humidity, giving the shoulders real protection against spalling and chunk loss. A crown coating job typically runs $290-$480 in Pemberwick.
Multi-Flue Cap
If your Pemberwick chimney carries two or more flues from separate units, a multi-flue cap is the only right answer. It covers the entire crown, not just individual flue openings, so rain, snow, and debris can’t find their way into the gaps between flue tiles. In older Pemberwick two-families, those gaps are often wide open, and a single-flue cap on just one opening leaves the shared smoke chamber exposed. A custom stainless multi-flue cap for a Pemberwick two-family stack typically runs $480-$850 installed.
Custom Cap
Some Pemberwick chimneys don’t fit anything off the shelf. Offset flue tiles, odd dimensions, decommissioned openings that still need weather protection but must breathe, or a crown with unusual geometry all call for a fabricated cap. We measure, fabricate, and install custom caps in stainless or copper, depending on what the roof and the budget allow. A custom cap in Pemberwick runs $520-$1,200, and we’ll show you the fabrication specs before we cut any metal. Every custom cap carries the same 90-Day Done Right Promise.

Trusted Brands We Service in Pemberwick
We install and service products from DuraFlex, Gelco, Copperfield, HeatShield, Olympia Chimney, and Famco because these brands have held up in Fairfield County’s freeze-thaw conditions and river-valley humidity. We know which stainless liner tolerates low-temperature gas exhaust without corroding, and which crown coating bonds properly to brick that never really dries out near the Byram River. For Pemberwick’s older two-family stock, we stock the most common cap sizes and coating materials locally, which means faster turnaround when your crown fails mid-winter and you don’t want to wait two weeks for a part. If a DuraFlex liner or a Gelco crown coat is what your chimney needs, we’ll show you the product and explain why it’s the right call before any work begins.
Common Chimney Cap & Crown Problems We See in Pemberwick Homes
- Crown mortar crumbling under freeze-thaw stress. Pemberwick’s temperatures cross the freezing mark dozens of times each winter. Water seeps into hairline cracks, freezes, expands, and pops small chunks of crown away. After a few seasons, the crown looks like a crumbling cookie and water is getting straight into the brick below.
- Open flues from decommissioned oil burners inviting rain into shared chimneys. When an oil burner comes out and a gas furnace goes in, the old oil flue is often left open with a partial cap or no cap at all. In a Pemberwick two-family, that open flue dumps rain into the smoke chamber your neighbor’s gas vent shares with you. The moisture moves through the brick, and both units feel it.
- Gas conversion condensation dissolving flue liners from the inside. Low-temperature gas exhaust condenses in an oversized clay flue that was built for coal or oil heat. That acidic condensate runs down the liner and eats away at the mortar joints between tiles. The cap above can look fine while the liner below is silently disintegrating.
- Failed coatings peeling away from damp brick. If a crown coating is applied to brick that holds river-valley moisture, it doesn’t bond. It peels, water gets under the edges, and the crown shoulders start losing chunks. You can sometimes see the peeled coating from the ground on a two-story Pemberwick two-family with a shallow roof pitch.

FAQs - Chimney Cap & Crown in Pemberwick
The only reliable way is a camera inspection from the roof. In a Pemberwick two-family, we lower a camera down each flue and trace the path while you watch the footage. You’ll see exactly which opening connects to your furnace, which one serves the neighbor’s appliance, and which ones are dead or decommissioned. We flag every opening and mark it on the report so there’s no guessing. Call (475) 242-5865 to schedule the inspection, and you’ll have your answer and the footage in your hands the same day.
Fix the crown first, then address the cap. A cracked crown lets water into the brick and flue regardless of what cap sits above it. In a converted Pemberwick rental, there’s usually a second problem: the old oil flue was never properly capped, so rain has been entering the shared smoke chamber even when the crown was intact. We’d rebuild and coat the crown, then install the right cap or caps based on what the camera inspection shows in each flue. Expect $350-$680 for the crown and $240-$850 for the cap work, depending on how many flues we’re sealing. Call (475) 242-5865 for an exact quote; estimates are free.
A properly installed cap on the correct flue can stop exhaust from backdrafting into your unit, but only if we know which flue is which and what each appliance is doing. In Pemberwick’s converted two-families, the real fix is often a multi-flue cap with separate terminations for each flue, plus a verification that the gas liner is correctly sized for low-temperature exhaust. If the neighbor’s appliance is venting into an unlined flue that shares a smoke chamber with your unit, no cap alone will fully solve the transfer. We’d show you the camera footage and explain exactly what’s needed before quoting. Call (475) 242-5865 and we’ll schedule the inspection.
A Custom Cap is fabricated to the exact dimensions of your chimney crown and flue layout, rather than pulled off a shelf in a standard size. Pemberwick chimneys need them when the flue tiles are offset, the crown has unusual geometry, or there’s a decommissioned opening that still needs protection while remaining vented. Many two-families in this neighborhood have flue layouts that were never standardized, so a stock cap either leaves gaps or sits wrong. A custom cap in Pemberwick runs $520-$1,200 depending on material and size. Call (475) 242-5865 and we’ll measure and quote it precisely.
Once a year, burn or no burn. Chimneys break in the off-season too. Even when a Pemberwick home has been converted to gas and the fireplace never gets used, the crown still freezes and thaws, the cap still catches leaves and squirrel nests, and the liner still sees condensation from low-temperature exhaust. An annual cap and crown check takes about thirty minutes and costs far less than the crown rebuild or liner replacement you’re trying to avoid. If you’re in a two-family or converted rental, the inspection also covers the shared flues and verifies that the neighbor’s converted appliance isn’t actively damaging your side of the stack. Call (475) 242-5865 to book your annual check.
One More Thing About Pemberwick Chimneys
In Pemberwick, many chimneys on tightly spaced two-family homes still vent oil-to-gas converted appliances through shared masonry stacks. That means a single cap or crown failure doesn’t just affect one household. It sends moisture and exhaust into both units’ flues, and neither owner may realize it until the staining shows up on a party wall or the gas furnace starts backdrafting. This is the reality of Pemberwick’s housing stock, and it’s why we treat every shared stack as a system, not a single opening. In a Pemberwick two-family off Byram Road, we found the original clay flue liners badly spalled after a gas conversion left oversized flues condensing low-temperature exhaust. We installed a custom stainless multi-flue cap over both flues and rebuilt the cracked crown with a Gelco crown coat, restoring draft and keeping the shared stack dry through the next freeze-thaw cycle.
If you own or rent in Pemberwick and you haven’t had the chimney looked at since the last heating conversion, call (475) 242-5865. We’ll get on the roof, run the camera, and tell you exactly what’s going on up there. No upsell, no scare tactic, just the footage and a straight answer. That’s how we’ve done it since 1999, and it’s why Pemberwick keeps calling us back.
