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 East Northport
A chimney cap or crown replacement in East Northport typically runs $350-$900 for a standard single-flue cap, and $750-$1,800 when a multi-flue custom cap and full crown rebuild are needed together. Most jobs take one visit, and we’ll show you camera footage of exactly what’s wrong before you spend a dime on repairs. If you’re on Larkfield Road, Clay Pitts Road, or anywhere between Pulaski and Elwood, call (631) 318-8656 and we’ll get you a straight answer, not a sales pitch.
East Northport’s chimneys aren’t like the ones you’ll find in newer developments to the south. They’re older, they work harder, and they almost always have two flues sharing one stack. That changes how caps are sized, how crowns fail, and how much a proper fix should cost. Wendell Pike has been inside enough of these chimneys to know what he’s looking at before he sets the ladder. Top Hat Chimney has been doing this work since 1999, and we’re local enough that you’ll probably see the truck again next week.
Why Top Hat Chimney Is East Northport’s Preferred Chimney Cap & Crown Company
We’ve worked the North Shore long enough to know that East Northport’s housing stock has a personality all its own. The split-levels off Elwood Road, the Cape Cods near the Northport line, the raised ranches along 5th Avenue: most of them went up between 1952 and 1975, and most still have the original clay-tile flues. That’s not a criticism. It’s just the reality of working here, and it’s why our Chimney Cap & Crown work in this town always starts with two questions: how many flues are in that stack, and what’s the crown actually doing up there.
When you call, a live person answers. Around the clock. It might well be Wendell himself, and he’ll ask about your house before he asks about your credit card. We give you a real arrival window, and if it slips, we call you. Our crew shows up in uniform, background-checked, and they don’t start work until you’ve heard the number and seen it in writing. That number is the number on the invoice. No surprises at the door, no “we found something else while we were up there” games.
Every completed job is backed by the 90-Day Done Right Promise, in writing. If the cap leaks, the crown cracks again, or the damper doesn’t seat, one call brings Wendell back at no cost. That’s not a slogan. That’s just how we’ve done business for over 29 years. Homeowners between 50 and 70 in these neighborhoods have told us they’ve been burned by national outfits before: a stranger shows up, the price changes, and the phone goes quiet afterward. We’re the opposite of that. Published address, published license number, and the owner puts his name on the work. Ask anyone on your street.
Our Chimney Cap & Crown Services in East Northport
Multi-Flue Cap Installation
This is the service East Northport calls about more than almost anything else, and it’s because of how these houses were built. That single chimney stack on your split-level or Cape Cod often carries two separate flues: one for the fireplace, one for the oil burner. A generic big-box cap won’t fit right, and worse, it won’t vent both flues correctly. We measure the crown, check the spacing between flue tiles, and fabricate a custom stainless multi-flue cap, usually from Olympia Chimney or Copperfield, that covers both openings and keeps out rain, leaves, and the raccoons that think your chimney is a condo.
Cap Replacement
If your cap is rusted through, missing, or was never installed properly in the first place, we’ll replace it with stainless steel that’s sized for East Northport’s actual conditions. That matters here because the oak canopy over neighborhoods like Clay Pitts and Cedar Road drops a lot of debris each fall. A loose or undersized cap means leaves and twigs down the flue, which blocks draft and becomes a fire hazard. We’ll remove the old cap, check the flue underneath, and install a replacement that’s anchored to stay put through Nor’easter winds off the Sound.
Crown Repair and Rebuild
The chimney crown is the concrete slab that caps the very top of the masonry. On East Northport homes built in the 1950s and 60s, those crowns have been through 50 to 70 winters of freeze-thaw cycles, and Long Island Sound keeps the air damp enough that the damage compounds faster than inland. Small cracks can sometimes be sealed. A crown that’s spalling, crumbling, or pulling away from the brick needs a full rebuild with a proper overhang and a flexible sealant that moves with the chimney. We’ll show you the camera footage first, then give you a plain-English verdict on which one you actually need.
Crown Coating
When the crown is still structurally sound but starting to show hairline cracking, a high-quality flexible coating can buy you years and keep water out of the flue. But we’re direct about this: coating is a maintenance measure, not a lifetime fix. If the crown has already separated from the brick or the mortar bed is failing, no coating will save it, and we’ll tell you so. We’d rather lose the upsell than send you back up there in two years. For East Northport’s older masonry, CrownSaver or similar flexible sealant applied correctly is a smart, economical step between full rebuilds.

Trusted Brands We Service in East Northport
We install and work with products from Olympia Chimney, Copperfield, DuraFlex, and Gelco. That’s not name-dropping for the brochure; those are the brands that hold up through Long Island winters without warping at the seams or rusting out after three seasons. We keep common cap sizes and crown sealant in stock for East Northport jobs, which means we’re not waiting on a shipping delay while your flue sits open to the weather. When a custom cap is needed for a dual-flue stack, we measure, order, and usually install within a week or two.
Common Chimney Cap & Crown Problems We See in East Northport Homes
- Freeze-thaw crown cracking. The damp air off Long Island Sound pushes moisture into every hairline crack, and each winter freeze widens it. By Year 50, most original crowns are fissured or spalling, and water gets behind the brick, which then cracks the flue tiles below.
- Oak-leaf loading in uncapped flues. The mature oak canopy over much of East Northport drops leaves and acorns into any open flue every fall. That debris blocks draft for the oil burner and gives sparks something to ignite. A properly fitted cap is not optional in these neighborhoods.
- Chimney swift and raccoon nests. The same canopy that drops leaves also makes uncapped chimneys prime spring habitat for chimney swifts, a federally protected migratory bird, and the occasional raccoon. April and May calls in East Northport often require clearing an active or recent nest before any other work can start. A stainless cap with proper screening ends that cycle.
- Sulfur and creosote mixing in shared stacks. When a fireplace flue and an oil-burner flue share one chimney, cracks in the crown or interior masonry let sulfur-laden exhaust mix with creosote deposits. That combination accelerates corrosive third-degree buildup. We see it regularly in this town, and it’s why we inspect both flues even when the homeowner only asked about a cap.
Pricing for Chimney Cap & Crown in East Northport, NY
Here are the numbers, plain. A standard stainless single-flue cap install in East Northport runs $350-$550. A replacement cap on a two-flue stack starts around $650 and goes to $900 depending on the crown’s condition. Full custom multi-flue cap work with a crown rebuild, the kind of job the split-levels off Laurel Road often need, generally lands between $1,100 and $1,800. Crown coating alone is $400-$700 when the crown is still intact. What drives cost is flue count, crown size, and how much of the old mortar bed needs to be cut back and replaced. We offer a free estimate, a free second opinion on any competing written estimate, $40 off any repair over $200, and 10% off always for seniors and veterans. No trip charge inside the county.
Key Takeaways
- East Northport cap and crown work usually means dealing with two flues in one stack.
- Cracked crowns are the quiet cause of most clay-tile liner failure in 1950s-1970s homes.
- Heavy oak leaf loading makes caps a functional necessity, not an accessory.
- We don’t recommend any repair without camera footage you can see for yourself.

FAQs - Chimney Cap & Crown in East Northport
Yes, and it’s not just about leaves. A standard cap on a two-flue stack often doesn’t cover both flue openings correctly, leaving one exposed to debris and nesting birds. East Northport’s dense oaks mean your cap has to handle heavy leaf load each fall, so we recommend a custom stainless multi-flue cap sized to your crown’s exact dimensions with proper screening to keep out chimney swifts and raccoons. Big-box caps just don’t fit these 1950s-era stacks. Call (631) 318-8656 and we’ll measure it right.
From the ground, look for small concrete or mortar fragments in the gutter, on the roof slope below the chimney, or in the mulch at the chimney’s base. You may also see visible cracks running across the top surface from an upstairs window or the street. Dark streaks down the brick below the crown are another tell, they suggest water is getting in and carrying soot or mineral staining down the masonry. If you see any of those, call us and we’ll put a camera on it. Estimates are free.
Yes, absolutely. That oil-burner flue vents exhaust year-round, and an uncapped opening lets rain, leaves, and animals into a flue that’s already carrying sulfur-laden fumes. Water mixing with sulfur deposits creates a mild acid that eats mortar joints from the inside. A simple stainless cap on the oil flue is one of the cheapest protections you can buy for a 1950s East Northport chimney. Call (631) 318-8656 for an exact quote.
Sometimes. If the crown has hairline cracks but is still solid and bonded to the brick, a quality flexible coating like Gelco or CrownSaver will seal it up and stop further water intrusion for years. But if the crown is spalling, crumbling, or pulling away from the masonry, no coating will hold, and a rebuild is the honest fix. We’ll show you the camera footage and tell you which one your chimney actually needs. We won’t send you up there twice.
Because the outside of the chimney rarely tells the whole story. A crown can look cracked but the flue tiles beneath may be fine, or the cap can look serviceable while the flue behind it has a chimney swift nest and three seasons of leaf debris. In East Northport, where most homes have dual-flue stacks from the 1950s and 60s, problems hide in the shared masonry between flues. We run a camera down both flues before we quote anything, and you watch the footage with us. The video and the verdict, every time, no exceptions.
