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 Larchmont
A chimney cap and crown in Larchmont typically runs $380-$1,100 for a standard replacement, and most jobs are finished in a single visit. The real cost driver here is salt air from Long Island Sound, which eats through galvanized components far faster than anyone expects. If your cap is pitted, rusted through, or missing entirely, call (914) 685-6096 and Wendell Pike will give you a straight answer on what needs doing and what can wait. We’re in Larchmont Manor, Murray Avenue, and the streets off Boston Post Road regularly, and we know exactly what the coastal exposure does to these older chimneys.
Why Top Hat Chimney Is Larchmont’s Preferred Chimney Cap & Crown Company
Wendell founded Top Hat Chimney in 1999, and since then the work has stayed owner-operated. No franchise rotation, no stranger at the door who’s never seen a salt-corroded chase cover. When someone in Larchmont calls about a failing crown or a rusted cap, Wendell or one of his background-checked crew members shows up in uniform, gives a real arrival window, and calls if that window slips. That matters in a village where half the chimneys date to the 1920s and the other half should have been inspected after the last coastal storm.
Larchmont homeowners tell us the same thing: they’ve been burned by outfits that quote one price on the phone and another at the door. That does not happen here. The number you hear before we arrive is the number on the invoice. Every job, including Chimney Cap & Crown work, carries the 90-Day Done Right Promise in writing. If it’s not right, one call brings Wendell back. Ask anyone on your street.
Our Chimney Cap & Crown Services in Larchmont
Here’s the specific work we do on chimneys across Larchmont, from Larchmont Manor down to the waterfront streets near the Sound. Each one gets the same treatment: camera inspection, plain-English verdict, and a price that does not change.
Cap Installation
New caps on Larchmont chimneys should be stainless steel or copper, full stop. Galvanized caps fail within five to seven years here because of chloride in the air off the Sound. We install stainless steel multi-flue and custom caps that hold up to the environment, and we flash them properly so the roofline doesn’t start leaking. Standard installation on a single flue runs $350-$650; a custom multi-flue cap in Larchmont is usually $700-$1,200 depending on flue count and footprint.
Cap Replacement
If your current cap is rusted through at the seams or the drip edge is separating, it’s not doing its job. Rain gets in, animals get in, and the flue liner starts deteriorating. We replace failed caps with stainless or copper units sized to your chimney, not whatever is on the truck. Replacement on most Larchmont homes runs the same range as new installation, $350-$1,100, and we haul the old cap away.
Crown Repair
Larchmont’s original mortar crowns, poured between 1890 and 1940, are failing faster than their age would predict. Salt sits in the mortar during warm months, then freeze-thaw cycles through the winter crack it open. We grind back deteriorated crown surface, rebuild the slope so water sheds away from the flue, and seal the work. Typical crown repair in Larchmont runs $500-$1,300. Once the crown fails, brick spalling follows fast.
Crown Coating
For crowns that are still structurally sound but showing surface cracking, a coating buys years of protection without a full rebuild. We use Gelco crown coat on these jobs in Larchmont because it stands up to salt-laden moisture better than standard elastomerics. Coating runs $400-$800 for a typical single-family chimney. It is not a fix for a crown already spalling at the edges, and if yours is too far gone, Wendell will tell you straight.

Trusted Brands We Service in Larchmont
On Larchmont jobs we use Famco stainless steel caps, Gelco crown coating, and Olympia Chimney components most often.

Because we’re in this area every week, we keep common cap sizes and crown repair materials on hand, which means most Larchmont calls are one trip, not two. When you call (914) 685-6096, the person who answers can tell you what we’ll likely need and whether we can get it done that week.
Common Chimney Cap & Crown Problems We See in Larchmont Homes
- Galvanized caps rusting through at the seams. Chloride in the air from Long Island Sound eats galvanized steel alarmingly fast here. We’ve pulled caps off Larchmont Manor homes that were less than five years old and already had daylight through the seams.
- Original mortar crowns cracking and spalling. The 1890s-to-1930s chimneys that dominate this village have crowns that were poured without modern expansion joints. Salt-fostered freeze-thaw cycles open them up, and water gets into multi-wythe brick. The crown goes first, then the bricks.
- Flashing corrosion at the roofline. Where the chimney meets the roof is exactly where salt water collects and copper or galvanized flashing fails. We find hidden attic and wall leaks on Larchmont homes that homeowners thought were roof problems.
- Converted-to-gas flues that were never properly reassessed. When a Larchmont heating contractor swaps an oil boiler for gas, the flue gets rerouted but the original unlined masonry often goes untouched. The cap and crown may be original too, which means the whole assembly is now handling gas exhaust it wasn’t built for.

FAQs - Chimney Cap & Crown in Larchmont
Every year, no exceptions. Salt from Long Island Sound works into crowns and cap seams constantly, and by the time you see visible rust or spalling from the ground, the damage has usually been underway for a year or more. In Larchmont specifically, we recommend an inspection every spring, after the winter storm season has driven ocean moisture inland. Call (914) 685-6096 to schedule, and Wendell will put camera footage in front of you so you’re not taking anyone’s word.
Yes. Galvanized caps corrode through within five to seven years on chimneys near the Sound, and some go faster depending on how much salt spray reaches the roofline. Stainless steel costs more up front but lasts decades here. If your current galvanized cap is still intact, replacement can wait. If it’s rusted at the seams or the drip edge is gone, it’s no longer protecting the flue. We’ll show you the condition and let you decide.
Usually the crown, because it’s the original mortar from the 1920s and it’s been absorbing salt for a century. Freeze-thaw cycles crack it, water gets into the top courses of brick, and spalling follows. The cap often fails slower but more visibly, rusting through at the seams. On Larchmont Manor Tudors specifically, we regularly find both failing at once because the home’s last service was a gas conversion that never touched the top of the chimney.
Yes, and sometimes more. Flashing sits in the water path, not just near it. Chloride-laden moisture collects at the chimney-roof junction, sits against copper or galvanized flashing, and corrodes it. We find hidden leaks into Larchmont attics and wall cavities that were misdiagnosed as roof failures. When we do a cap or crown job, we inspect flashing and tell you plainly if it needs replacement or can wait.
It’s a common problem in Larchmont, and yes, it usually matters. A gas conversion reroutes the flue but often leaves the original unlined masonry and the old crown in place. That means gas exhaust is moving through a chimney that was never properly relined or assessed, and the crown may be spalling and letting in salt water at the same time. We see this pattern constantly in Larchmont Manor. Call (914) 685-6096 for a free inspection and we’ll show you exactly what’s going on with camera footage. No obligation, just the truth.
If your chimney cap or crown needs attention in Larchmont, call Wendell at (914) 685-6096. You’ll get a live person, a straight price, and work backed by the 90-Day Done Right Promise in writing. The estimate is free, whether you book the job or not.
