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.
Fast, Reliable Chimney Cap & Crown Across North Merrick
A chimney cap and crown replacement in North Merrick typically runs $450-$1,400, and most jobs are done in a single visit. The real variable is what we find underneath: a cracked crown on a 1950s Cape Cod often means water has already started working on the clay flue tiles. Call (516) 963-1068 and we’ll come take a look with a camera before anyone reaches for a trowel.
North Merrick’s homes were built fast and built well, but the chimneys on those post-WWII ranches and split-levels are now 60 to 80 years old. The salt-laden air off the Great South Bay doesn’t help. We know these stacks, we know how they fail, and we know when a repair can wait. That last part matters, because this is the line of work where the most upselling happens.

We also understand the specific failure patterns of Chimney Cap & Crown in North Merrick housing stock better than most. That’s not marketing. It’s the difference between a crew that has worked Jerusalem Avenue splits and Little Whaleneck area Capes for years, and a crew working off a GPS and a generic checklist.
Our Chimney Cap & Crown Services in North Merrick
The Chimney Cap & Crown work on these older North Merrick homes falls into a few clear categories. Here’s what we actually do, and how it applies to the houses around here.
Cap Installation
A new stainless or copper cap on a North Merrick chimney runs $250-$600 installed, depending on flue size and material. On the Cape Cods and split-levels built between 1945 and 1965, a proper cap does more than keep rain out. It keeps squirrels, raccoons, and starlings from turning your flue into a winter nest. We size caps to the tile, not to whatever’s on the truck.

Cap Replacement
Rusted single-flue caps are common on North Merrick homes where the furnace was converted from oil to gas and the old oil-furnace flue was abandoned. That flue still needs a cap. Replacement ranges from $200-$500, and we’ll always show you the corrosion before we swap it. If the cap is just ugly but structurally sound, we’ll tell you that too and save you the money.

Crown Repair
A failing crown on a North Merrick chimney is the leading entry point for water, and water is what kills these old stacks. Crown repair runs $600-$1,200 depending on whether we’re patching, rebuilding, or forming a new crown with a proper drip edge. The salt moisture off the South Shore bays accelerates crown cracking here, and once water gets under the crown, freeze-thaw cycles do the rest. We use a Portland-based crown mix formulated for coastal Long Island conditions, not the $12 bag from the big box store.

Crown Coating
When a crown is sound but showing hairline cracks, a flexible crown coating can buy it years for $350-$700. We use Gelco and Olympia Chimney products, which are built for exactly the expansion and contraction North Merrick’s humid springs and cold winters put these chimneys through. Coating isn’t always the right answer; sometimes the crown needs a rebuild. The camera will tell us which, and we’ll show you the footage.

Custom Cap
Odd flue sizes on 1950s masonry chimneys often won’t take an off-the-shelf cap. We fabricate custom stainless and copper caps for North Merrick homes with oversized or unusually spaced tiles, typically $500-$900 including installation. Famco and Copperfield are our go-to sources for custom work. If your flue came from a local mason in 1954, it may be exactly 8 1/2 by 8 1/2. Tiles aren’t always nominal.

Multi-Flue Cap
This is the one we emphasize on North Merrick’s dual-flue chimneys. A multi-flue cap covering both the fireplace flue and the old furnace flue runs $450-$850, and it solves the problem that kills these homes: the abandoned flue going uncapped for years. One cap, two flues, no rainwater pouring down a liner nobody uses until it collapses. We install more of these in North Merrick than nearly any other single product.

Trusted Brands We Service in North Merrick
We install and service caps and crown materials from Gelco, Olympia Chimney, Famco, and Copperfield. These are the names that hold up in coastal Nassau County conditions. We keep common sizes and parts stocked for North Merrick jobs, so a standard cap replacement doesn’t turn into a two-week parts-wait. And because we work with these manufacturers directly, we can get custom fabrications turned around faster than a crew ordering through a third-party distributor.
Common Chimney Cap & Crown Problems We See in North Merrick Homes
- Salt-accelerated crown cracking. North Merrick sits a couple miles north of the South Shore bays. The persistent salt-laden humidity off Merrick Bay weakens mortar joints and crown edges, and then winter freeze-thaw cycles split them. We see crowns cracked wide open before their 15th year, and we see far less of this inland in Garden City or Westbury.
- Abandoned furnace flues with no cap at all. Gas conversions in post-WWII Capes and ranches left thousands of old oil-furnace flues sealed off at the bottom and forgotten. The cap rusted away years ago. Rain gets in, soaks the clay tiles, and the tiles spall until the flue is unsafe. The active fireplace flue next to it usually drafts fine, so nobody notices until the camera goes in.
- Hard Portland cement repointing from the 1980s and 1990s. A well-intentioned DIY fix that did more harm than good. Hard mortar doesn’t breathe, so moisture gets trapped behind it. In North Merrick’s humid bay air, those bricks spall and the crown separates from the flue liner. We use softer, lime-based repointing when we repair crowns and upper courses. Out-of-area crews often never check.
- Rusted single-flue caps on active fireplace flues. These last 10 to 20 years in this climate before the salt and rain take them. A rusted-through cap still looks fine from the ground, but it’s letting water run down the flue every time it rains. We change more of these than we rebuild crowns.

FAQs - Chimney Cap & Crown in North Merrick
Because the old oil-furnace flue gets abandoned and forgotten. When a 1950s North Merrick home converts from oil to gas, the furnace flue is sealed at the bottom and left uncapped at the top. Rain, salt air, and animals get in, the clay tiles spall, and years later the crown is cracked and the flue is shot. The active fireplace flue may work fine, so nobody looks. Homes that never converted still vent hot oil exhaust up that flue, which keeps it drier and less inviting. Call (516) 963-1068 and we’ll camera both flues, even the one you think is dead.
Almost always, yes. If the crown is cracked but the underlying masonry is sound, we can remove the damaged crown, form a new one with a proper drip edge, and repair the upper courses in a single visit. Full chimney-top rebuilds are only needed when the bricks themselves have spalled badly or the flue liner has separated, and that’s rare. We’ll show you the camera footage before we recommend anything.
Yes, and that’s the single most common cap mistake on North Merrick’s Capes. A multi-flue chimney needs a multi-flue cap that covers both the fireplace flue and the old furnace flue. Many homes have two separate single-flue caps that don’t seal the area between the flues, so water still gets in. We fabricate custom multi-flue caps sized to the actual tile spacing, usually for $450-$850. One cap, both flues protected.
Because they don’t know what they’re looking at. North Merrick’s specific history, post-WWII dual-flue construction, gas conversions, salt humidity, and 1980s-era Portland cement repointing, produces failure patterns that don’t show up in a generic training video. Out-of-area crews look for the obvious crack, snap a photo, and leave. We look for the abandoned flue, the trapped-moisture spalling, and the salt-weakened crown edge. That’s the difference. The camera doesn’t miss, and we show you everything.
Every year, burn or no burn. Chimneys break in the off-season too. The crown and cap see the worst weather in the winter when you’re not even using the fireplace, and salt-laden humidity works on the mortar year-round. An annual inspection with a camera takes under an hour, and if everything’s sound, you’re out the inspection fee and done for the year. If we find early crown cracks, a $350-$700 coating beats a $1,200 rebuild. Call (516) 963-1068 to book one.
North Merrick’s Dual-Flue Chimney Problem
Here’s the thing about North Merrick’s housing stock: most of those Capes, split-levels, and ranches built between 1945 and 1965 were designed for oil heat. The chimneys had two flues, one for the fireplace and one for the oil furnace. The clay tile liners were sized for oil’s high exhaust temperatures. Then the gas conversions came. Over the last two decades, Nassau County homeowners have steadily switched to gas, and that old oil flue, now venting lower-temperature gas exhaust or sealed off entirely, isn’t doing what it was built to do.
When the furnace flue gets abandoned after a gas conversion, the crown and cap above it rarely get inspected. The cap rusts away. Rain gets in. The salt-laden air off Merrick Bay and the Great South Bay accelerates the decay. The clay tiles spall, the mortar joints erode, and the crown cracks wide open. All of this happens above the roofline, out of sight, while the homeowner’s fireplace flue, the one they actually use, keeps working fine. Until it doesn’t.
On a split-level off Jerusalem Avenue, our crew found exactly this. A cracked crown and a rusted single-flue cap were letting rain straight into the abandoned oil-furnace flue. The clay tiles in that flue were already spalling from years of salt-laden moisture. We installed a custom stainless cap over both flues, rebuilt the crown with a proper drip edge, and showed the homeowner the camera footage of the deteriorated liner before recommending any relining. That’s the sequence: evidence first, recommendation second. If we can’t show you the damage on camera, we don’t ask you to pay for the fix.
If your North Merrick home still has its original dual-flue chimney and you’ve converted to gas, book a cap and crown inspection before the heating season. The flue nobody uses is the flue that causes the most expensive problems.
