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 Old Greenwich
A new chimney cap or a rebuilt crown in Old Greenwich usually runs $225-$1,400 depending on flue count, cap style, and whether we’re repairing or replacing the cement crown beneath it. That’s a real range, not a teaser. Most jobs take one visit, and we’ll show you camera footage before we touch anything so you know exactly what’s wrong. Call (475) 242-5865 and Wendell or one of his crew will talk you through what you’re seeing.
We’ve worked the stretch from Shore Road up through the village core long enough to know what Old Greenwich chimneys do. The salt air off the Sound is not kind to caps and crowns, especially on the water-facing side. The team at Top Hat Chimney serves the whole of Old Greenwich, from Binney Park over to Greenwich Point, and we understand what the older housing stock here asks of a chimney. The number again: (475) 242-5865.
Why Top Hat Chimney Is Old Greenwich’s Preferred Chimney Cap & Crown Company
Wendell Pike founded Top Hat Chimney in 1999, and he still answers the phone. That’s not a slogan. Calls to (475) 242-5865 get a live person, around the clock, and more often than not the voice on the other end is the same guy who shows up at your door. People in Old Greenwich tend to value that, especially after dealing with the national outfits that send a stranger, change the price at the door, and vanish when you call back.
The company carries a 90-Day Done Right Promise in writing on every job. If the cap leaks or the crown cracks inside ninety days, one call brings Wendell back at no charge. He puts his name and license number on the work, and then he runs into you at the hardware store on Saturday. You can’t hide behind a call center when you live and work in the same communities.
Local knowledge matters here in a specific way. The crews working your Chimney Cap & Crown jobs have spent years learning how Sound-facing masonry behaves differently from the rest of Fairfield County. They know which streets catch the worst nor’easter wind. They know what a 1930s Colonial on Sound Beach Avenue is hiding behind that original cap.
Our Chimney Cap & Crown Services in Old Greenwich
Cap Replacement
A standard galvanized cap skirt on a Sound-facing chimney in Old Greenwich lasts three to five seasons before the salt air eats through it. Once the mesh detaches or the skirt corrodes, the flue is open to rain, birds, and whatever the next nor’easter drives sideways into the opening. We remove the old cap, inspect what’s underneath, and size a replacement to the actual flue dimensions rather than slapping on whatever’s on the truck. For two-flue stacks, we often recommend a Copperfield or Olympia multi-flue cap with stainless construction that holds up far longer against marine air. Most cap replacements in Old Greenwich run $225-$650 installed.
Cap Installation
Adding a first cap to a chimney that has never had one changes how the whole flue behaves. Many of the 1920s-1950s Colonials and shingle-style homes around Sound Beach and Arcadia Road still run open flues. That’s fine for draft, but it means every storm drops water straight down onto the smoke shelf. Around here, wind-driven rain is the bigger problem than vertical rain. A properly fitted cap with a screened spark arrestor keeps the water and the critters out without choking the draft. Installation runs $275-$700 for a single flue, more for custom multi-flue work.
Crown Repair
The cement crown is the flat, sloped slab that seals the top of the chimney and holds the cap in place. Original crowns on Old Greenwich homes from the 1920s through the 1950s were poured without expansion joints, so they crack under thermal cycling. Then nor’easter rain gets into the cracks, and the freeze-thaw cycle in February works the cracks wider. We repair failing crowns by cutting back damaged material and applying a bonded, sloped mortar bed that sheds water instead of holding it. On Sound-facing chimneys, we pay particular attention to the south/southeast exposure, where salt-air corrosion is worst. Crown repair in Old Greenwich typically runs $350-$850, sometimes less when we catch it early during a routine cleaning.
Crown Coating
When a crown is structurally sound but porous and losing its surface, coating it with a flexible, waterproof membrane can add five to seven years of life before a full rebuild is needed. This is a good option for homeowners whose crown has hairline cracking but no deep displacement. We inspect with the camera first, show you the footage, and tell you plainly if the crown is a candidate for coating or if it needs to be rebuilt. If it can wait, we’ll say so. Coating runs $275-$500 in Old Greenwich, and it’s one of the few jobs where the cheaper fix is often the right one.

Trusted Brands We Service in Old Greenwich
We install and service caps and related components from Copperfield, Olympia Chimney, Famco, Gelco, and DuraFlex. That’s not a brand list for show; we stock the parts most commonly called for on Old Greenwich work. Sound-facing chimneys need copper or high-grade stainless, not the cheap galvanized stuff, and we keep those on hand so we’re not ordering parts from a catalog while your flue sits open. Copperfield caps in particular hold up well to the marine air, which is why you’ll hear us mention them on waterfront homes along Shore Road and near the Greenwich Point coves.
Common Chimney Cap & Crown Problems We See in Old Greenwich Homes
- Rust streaks below the cap on the water-facing side. Salt-laden air attacks the windward side first. In Old Greenwich, that means the south and southeast face of the chimney degrades a full season before the street side shows anything, which is why a homeowner will say the chimney “looks fine from the street” while the Sound-facing cap skirt is already perforated.
- The street side looks intact, but the Sound-facing crown is spalling. Our crews routinely find cap seams and crown mortar on south/southeast exposures corroded or spalled months ahead of the leeward side. The tidal marshes near Greenwich Point keep ambient humidity high year-round, and that moisture works into the crown during every nor’easter, then freezes and pops the surface off.
- The cap is fine, but the terra cotta flue tiles beneath it are gone. This is one we find on original 1920s-1950s stacks all over the village core. The cap hides the real problem: spalled flue tiles at the top two courses. We scop the stack with a camera before recommending anything, because a rusty cap on a failed flue is the wrong order of operations.
- Moss and efflorescence on the chimney exterior. The humid air and salt spray around Greenwich Point and the coves feed moss growth on brick and mortar. Efflorescence is the white, chalky deposit left when water moves through masonry and evaporates. It’s a sign the crown or cap has stopped shedding water, and the staining usually tells us exactly where the failure is.

FAQs - Chimney Cap & Crown in Old Greenwich
Why does the chimney cap on my Old Greenwich home rust out faster than my friend’s cap in Stamford?
Salt air. Old Greenwich sits directly on Long Island Sound, and the prevailing wind carries salt-laden moisture onto Sound-facing chimneys. A standard galvanized cap that lasts six or seven years inland in Stamford will often fail in three to five seasons on Shore Road or anywhere near the waterfront. The fix is to put copper or high-grade stainless up there and stop replacing galvanized every few years. Call (475) 242-5865 and we’ll show you the corrosion pattern on your existing cap.
The street side of my chimney looks fine, but the side facing the water is crumbling. Is that normal here?
Yes, and it’s one of the most consistent patterns we see on Old Greenwich chimneys. Salt-laden air attacks the windward side first, so the south/southeast face of the chimney degrades while the sheltered side still looks almost new. The same thing happens to cap seams and crown mortar. That’s why our camera inspections always include water-facing footage, not just what you can see from the driveway.
Do I need a new crown if I am just getting a new cap?
Sometimes, and the camera tells us which way it goes. The cap sits on top of the crown, so if the crown is cracked or spalling, bolting a new cap onto it just means taking everything apart again in two years. We always inspect the crown as part of a cap replacement and show you what we’re seeing. If the crown is sound, you keep it and we just replace the cap. If it’s failing, you’ll see why in the footage before you approve anything.
Can I leave my chimney uncapped over the summer in Old Greenwich?
You can, but around here you’ll pay for it. The summer humidity near the marshes and the Sound keeps moisture moving through the flue even without rain. Open flues collect birds, squirrels, and leaves, and the next nor’easter will drive water straight into the smoke chamber. The humid air also accelerates rust on dampers and lintels. Cap it once and stop thinking about it. Call (475) 242-5865 and we’ll size the right cap for your flue.
My home inspector said the chimney crown looks okay. Why would your tech disagree?
Home inspectors look from the ground or the roofline edge, and they rarely scope the top two courses of the flue with a camera. On Sound-facing Old Greenwich chimneys, the worst damage is often on the side you can’t see from the street or the driveway. Our techs put a camera on the crown and down the flue, then show you the stills. We won’t tell you a crown is fine or failing based on a glance from the gutter line, and we won’t ask you to approve work based on our say-so either. You see the footage, and we talk it through in plain English.
