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
If you live in Old Greenwich and you’re wondering whether your chimney cap or crown needs attention, here’s the straight answer: a typical cap replacement in this town runs $350 to $650, crown repair or coating usually lands between $600 and $1,400, and the sooner you catch salt-air damage, the less it costs to put right. Top Hat Chimney has worked on chimneys from Shore Road to Havemeyer Park since 1999, and Wendell Pike and his crew know exactly what Long Island Sound does to masonry and metal. Call (475) 375-2748 and we’ll come out, put eyes on it, and tell you plainly what needs doing and what can wait.
That last part matters in Old Greenwich. The salt air off the Sound corrodes galvanized caps and eats mortar joints faster than you’d think. We’d rather tell you a crown needs coating than sell you a rebuild you don’t need. That’s how we’ve worked here for over 29 years, and that’s what this page is about.

Our Chimney Cap & Crown Services in Old Greenwich
Cap Installation
A chimney without a cap is an open pipe to the sky, and in Old Greenwich it’s also an open pipe to rain, salt spray, and the occasional squirrel looking for winter housing. We install stainless steel caps sized to your flue, whether you’ve got a single clay tile liner, a multi-flue stack, or a pre-fab chase. For homes within a half-mile of Greenwich Point, we always recommend stainless over galvanized. The salt air here puts a galvanized cap on a clock.
Cap Replacement
If you’re seeing rust streaks down the stack or hearing the rattle of a loose cap in a nor’easter, it’s time. A typical cap replacement in Old Greenwich runs $350 to $650, depending on flue count and access on the roof. On Shore Road near Greenwich Point, our crew replaced a corroded galvanized multi-flue cap on a 1920s Shingle-style home with an Olympia Chimney stainless cap. The original crown showed spalling and open joints from salt-laden onshore winds. We repaired the mortar and applied a Gelco crown coating, restoring draft and stopping water entry into the flue.
Crown Repair
The crown is the concrete slab that caps the chimney and keeps water out of the masonry. Crown wash failures from wind-driven salt moisture are among the most common defects we flag in Old Greenwich, particularly on pre-WWII chimneys where mortar has had decades to soften. If the cracking is cosmetic, we can patch and re-seal. If the crown is structurally shot, we’ll form and pour a proper replacement with a drip edge and expansion joint.
Crown Coating
On homes along the Sound, we often recommend crown coating as a preventive step even when the crown looks mostly intact. A Gelco crown coating seals hairline cracks before freeze-thaw cycles force them open. This is especially worth considering on homes from Binney Park down to the waterfront, where onshore winds drive salt moisture into mortar joints all winter. Coating a crown in Old Greenwich typically runs $600 to $1,100.
We also handle multi-flue caps and custom cap fabrication when your chimney has an unusual flue size or an old stone configuration that needs a cap built to measure.

Trusted Brands We Service in Old Greenwich
We stock parts and service products from Olympia Chimney, Famco, and Gelco, which means most cap and crown work in Old Greenwich can be completed in one visit. If you’ve got an existing Olympia cap that’s still solid but loose, we can re-secure and re-caulk it. If a Gelco coating was applied years ago and has started to wear on the seaward side, we can clean, re-seal, and re-coat. We don’t sell you a new system when the one you have is fixable.
Common Chimney Cap & Crown Problems We See in Old Greenwich Homes
- Rust streaks from corroded galvanized caps. Within a decade, the salt air near the Sound eats through galvanized steel. Rust runs down the stack, and the cap eventually collapses into the flue. We replace galvanized with stainless and call it done.
- Spalling crowns from wind-driven salt moisture. Hairline cracks open wider every freeze-thaw cycle. Left alone, chunks of the crown start breaking off. A Gelco coating or a full crown replacement stops it before water reaches the firebox.
- Open mortar joints on pre-WWII chimneys. Homes built between 1900 and 1945 often have stacked-stone or brick construction that absorbs coastal moisture. Once the crown fails, water soaks the joints from above. We repoint and then seal.
- Loose or missing multi-flue caps. If your home has multiple fireplaces or a fireplace plus a furnace flue, earlier cap installations often used the wrong-sized hardware. High winds off the Sound work them loose. We re-measure, re-fit, and re-anchor.

FAQs - Chimney Cap & Crown in Old Greenwich
Within a half-mile of Greenwich Point, you should have your cap and crown inspected every year, even if you burn rarely. The salt air and freeze-thaw cycles work even on an idle chimney. For homes farther inland, every one to two years is typically fine. If it’s been more than a few seasons since anyone looked, call (475) 375-2748 and we’ll schedule an inspection.
Because Old Greenwich sits directly on Long Island Sound. The persistent salt air and onshore winds deposit chlorides on metal caps and mortar joints, accelerating corrosion and spalling at a rate meaningfully faster than inland neighborhoods like Cos Cob or Glenville. Galvanized caps that might last twenty years in Hartford will show rust streaks here in eight to ten years.
Almost always, yes. Spalling on the surface layer doesn’t mean the entire chimney is compromised. We can chip away loose material, rebuild the crown’s edges, and apply a Gelco coating to seal the rest. The stack itself usually stays put. We’ll only recommend a rebuild if the masonry below the crown has structural damage, and we’ll show you the camera footage before we ever suggest it.
Stainless steel, every time. Galvanized caps will corrode within a decade in the salt air near the Sound. Stainless from Olympia Chimney or Famco holds up to the chloride exposure and doesn’t leave rust streaks down your stack. It costs more up front, usually $100-$200 more per cap, and it’s worth it in Old Greenwich.
When a crown fails, water enters the flue and soaks into the masonry and any cracked flue tiles. Damp flues don’t draft. Fires get smoky, hard to start, and eventually gas inserts and wood stoves backdraft. Fix the crown, dry the flue, and draft usually returns. If it doesn’t, there may be liner damage too, and we’ll show you exactly what the camera sees. Call (475) 375-2748 for an exact quote; estimates are free.
