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 Commack
Chimney cap and crown work in Commack usually runs $295 to $1,100 depending on whether we’re repairing a crown, coating it, or installing a new multi-flue cap. Most Commack homes are ranches, capes, and split-levels built between 1950 and 1975, and the original masonry chimneys are now 50 to 70 plus years old. That age matters because the crowns at the top of those chimneys were poured with basic concrete and have been taking freeze-thaw abuse for half a century. When you call Top Hat Chimney at (631) 502-3612, Wendell or one of his crew heads out to Commack, gives you a straight quote before any tool comes off the truck, and shows you exactly what’s going on with camera footage before you spend a dime on repairs.
Why Top Hat Chimney Is Commack’s Preferred Chimney Cap & Crown Company
Top Hat Chimney has been owner-operated since 1999, and Wendell Pike answers the phone himself more often than not. Commack homeowners don’t want a franchise crew that rotated in from somewhere else last season. They want someone who knows what a 1965 ranch off Old Commack Road looks like from the roofline down. Wendell has worked these neighborhoods for decades, and the business model hasn’t changed: live person answers the phone 24/7, background-checked crew in uniform shows up on time, and the price quoted on the phone is the price on the invoice.
Every job is backed by the 90-Day Done Right Promise in writing. If something isn’t right, one call brings the crew back at no additional cost. That matters in a town like Commack, where the housing stock has very specific failure patterns. The 1960s colonials near Jericho Turnpike, the capes north of the Northern State, the split-levels off Harned Road: these homes all were built around fuel-oil heat, and the chimneys show it. We know what we’re looking at before we even get up the ladder.
Our Chimney Cap & Crown Services in Commack
Cap Installation
A properly sized cap keeps rain out of the flue and stops squirrels, raccoons, and birds from nesting in a chimney that still vents your converted gas furnace. In Commack, the original clay tile flues are often oversized for the high-efficiency gas equipment they now serve. That doesn’t prevent cap installation. It does mean we measure carefully and size the cap to the existing flue tile, not to the appliance. We stock Copperfield and Famco caps in common Commack tile sizes, so most installations are done same visit.
Cap Replacement
Missing or rusted caps on Commack’s original clay tile flues let rain and animals into chimneys that still vent converted gas furnaces, blocking draft and risking carbon monoxide backup into the house. We see rusted-out caps all over Commack, especially on the older ranches where the cap was installed with the original oil burner in 1962 and nobody’s touched it since. Replacement is straightforward, but we won’t put a new cap on a crown that’s falling apart underneath it. We’ll show you what we’re seeing first.
Crown Repair
The concrete crown at the top of a Commack chimney is the first thing to fail in our freeze-thaw winters. Repeated freezing and thawing of water soaked into the concrete spalls the surface, opens cracks, and lets water run down into the flue and the attic. A cracked crown doesn’t just leak. It lets flue gas escape during furnace start-up and erodes the clay tile joints below. We repair crowns with Gelco CrownSeal, which handles the freeze-thaw cycling better than the original concrete ever did. Most Commack crown repairs are done in one visit and cost between $380 and $650.
Crown Coating
A crown that is still structurally sound can often be protected with a coating instead of a rebuild. But we don’t coat over a crown that’s already spalling to pieces. We camera-scope everything and show you the footage. If coating makes sense, we recommend it and explain why. If a rebuild is the honest call, we say that too, and we show you the price before you commit.
Multi-Flue Cap
Commack’s older chimneys often have separate flues for the fireplace and the oil furnace or the gas furnace that replaced it. A single-flue cap on a multi-flue chimney is a problem. It can cause cross-contamination and backdrafting into living space. We install Copperfield multi-flue caps sized to cover the entire flue array, with separate venting for each tile. That’s a job we’ve done on dozens of Commack chimneys, and it’s frequently the fix when a homeowner complains about fumes after the furnace kicks on.

Trusted Brands We Service in Commack
We work with top-tier chimney product brands because Commack chimneys are not the place for off-brand parts. Copperfield caps, Famco caps, Gelco CrownSeal, HeatShield liners, and DuraFlex liners. Most of the common cap and crown materials are on our trucks. That means we don’t quote you a job and then tell you the parts are on order. For Commack homeowners, that speed matters when your crown is open to the weather and the next freeze is a week out.
Common Chimney Cap & Crown Problems We See in Commack Homes
- Spalled concrete crowns from freeze-thaw cycling. Wet Atlantic-influenced winters with repeated crossings of the freezing point accelerate mortar erosion and spalling on the aging masonry chimneys throughout Commack. The crown is the first thing to go. Water gets in, freezes, expands, and pops the surface concrete off in chunks.
- Missing or rusted caps on original clay tile flues. In homes that still vent converted gas furnaces, an uncapped flue lets rain and animals block the draft path. The result is furnace exhaust that can’t leave the house properly. We find birds’ nests in uncapped Commack flues regularly.
- Single-flue caps on multi-flue chimneys. These 1960s and 70s Commack homes often have separate flues for the fireplace and the furnace. Someone slaps a single cap on top, and the cross-contamination creates backdrafting. The furnace exhaust can end up in the living room. This is not a cosmetic issue.
- Clay tile liner erosion below a failed crown. Water entry through a cracked crown doesn’t just damage the crown itself. It runs down the flue, attacks the mortar joints between clay tiles, and causes flue gas leakage during furnace start-up. We see this on Commack chimneys that haven’t been cleaned or inspected since the oil burner was swapped for gas.

FAQs - Chimney Cap & Crown in Commack
Because the crown and the cap are two different things. The cap is metal and sits over the flue opening. The crown is the concrete slab that covers the top of the chimney structure itself. In Commack, those crowns are 50 to 70 years old and have been through hundreds of freeze-thaw cycles. A crown can be cracked to pieces underneath while the cap still looks fine from the ground. We inspect both, and we show you camera footage before we recommend any work. Call (631) 502-3612 for an inspection.
Yes. We size the cap to the flue tile, not to the appliance. A cap that fits the tile correctly will shed rain and keep animals out regardless of what’s venting through it. We stock Copperfield and Famco caps in common Commack tile sizes, so most jobs are done the same day we inspect. If the liner itself is deteriorated or oversized beyond what a cap can address, we’ll show you the camera footage and talk through options, including a HeatShield reline.
A cracked crown shows up as hairline fractures on the flat surface, spalled patches where the surface concrete has popped off, or visible gaps along the edge where the crown meets the brick. Most Commack split-levels have crowns that can be repaired with Gelco CrownSeal rather than demolished and re-poured. That’s a one-day job in most cases, typically $380 to $650. If the crown has failed catastrophically, we’ll show you why a rebuild is the honest call.
Yes. The most dangerous call we get in Commack is from a homeowner who thinks the old chimney is dead and doesn’t need attention. But if the chimney still vents your gas furnace or water heater, it’s an active venting system. An uncapped, uninspected flue can block draft, cause CO backup, and add moisture and animal debris to the mix. We inspect everything with a camera and tell you plainly what needs attention and what can safely wait. Call (631) 502-3612 for a straight answer.
A camera inspection answers it in about 20 minutes. We run the scope up from the cleanout and from the fireplace, and we’ll show you the footage on the spot. If the fireplace and the furnace are venting into the same flue tile, we’ll document it and explain exactly what it means: draft problems, backdrafting risk, and a configuration that current code does not permit. That colonials off Jericho Turnpike and the adjacent neighborhoods are where we see this most often in Commack. The fix is usually a HeatShield or DuraFlex reline, sized correctly for each appliance, and we’ll quote it before any work begins.
