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 Dix Hills
Chimney cap and crown work in Dix Hills is not a one-size-fits-all job. The colonials and split-levels out here, most built between the mid-1960s and late 1980s, carry oversized multi-flue masonry chimneys that a standard cap simply will not cover. When you call Top Hat Chimney at (516) 968-5380, you get Wendell Pike and his crew, a locally owned team that has worked Long Island chimneys since 1999. We show up with the right materials, give you a straight price before any tool comes off the truck, and stand behind the work with our 90-Day Done Right Promise in writing. No call center, no stranger swapped in at the last minute. Just a sweep who will run into you again at the hardware store.
Why Top Hat Chimney Is Dix Hills’s Preferred Chimney Cap & Crown Company
Ask anyone on your street. Wendell has been climbing onto Dix Hills rooftops long enough to know what the salt air off Long Island Sound and the Great South Bay does to a galvanized cap over twenty winters. That local knowledge changes the job. We are not reading a spec sheet; we are looking at the same spalled crown patterns we have seen on Burrs Lane, Ryder Avenue, and the streets off Deer Park Road for decades. Our Chimney Cap & Crown crew carries custom Copperfield and Olympia multi-flue caps sized for the double-flue colonials that define this town, not whatever is stacked in a warehouse. Wendell puts his name and license number on every invoice, and if the work is not right, one call brings him back. That is the whole guarantee.
We answer the phone live, 24/7. It may well be Wendell himself picking up. When he schedules a visit to your Dix Hills home, you get a real arrival window, and if he is running behind, he calls you. No national franchise rotating a different crew through each season. The same owner, the same crew, the same promise: upfront pricing before any work begins, and the number you hear on the phone is the number on the invoice.
Our Chimney Cap & Crown Services in Dix Hills
Cap Installation
Standard single-flue caps do not fit most Dix Hills chimneys, because there is usually more than one flue up there. We install properly sized caps that keep rain, squirrels, and nor’easter-driven debris out without choking the draft. A cap that fits wrong can force smoke back into the house on a windy night. A cap that fits right keeps your flue breathing the way it should.
Cap Replacement
A rusted-through expanded metal mesh on a twenty-year-old cap is not a small problem. It is an open invitation for birds to nest, for leaves to pack the flue, and for rain to pour straight down onto decades of creosote. We have replaced corroded caps all over Dix Hills, and we always check what the salt air has done to the crown underneath while we are up there. If the cap failed, the crown usually needs attention too.
Crown Repair
The crown is the concrete slab that seals the top of the chimney. In Dix Hills, forty to sixty years of freeze-thaw cycles and salt-driven erosion leaves crowns cracked, spalled, and letting water into the flue structure. That water mixes with creosote and forms an acidic slurry that eats clay-tile liners from the inside. We rebuild crowns properly, with a flexible crown coating that moves with Long Island temperature swings instead of cracking the first February after installation.
Crown Coating
When the crown is structurally sound but showing hairline cracks, a heavy-duty flexible crown coating seals it before water gets in. This is the smart, lower-cost move that stops a minor crack from becoming a full crown tear-out three years later. Wendell will tell you plainly if your crown only needs coating or if it is too far gone and needs a rebuild. Either way, you see the condition yourself before you spend a dollar.

Trusted Brands We Service in Dix Hills
We install and service products from HeatShield, Olympia Chimney, and Copperfield because these are the brands that hold up in Dix Hills’s salt-air environment. We keep a stock of common cap sizes and crown repair materials ready for the oversized multi-flue chimneys out here, so most of the time we can complete the job in a single visit.

We diagnose the specific issue, show you exactly what went wrong, and tell you honestly what needs replacing now and what can wait.
Common Chimney Cap & Crown Problems We See in Dix Hills Homes
- Salt-air corrosion on galvanized caps. Dix Hills sits between Long Island Sound and the Great South Bay, and that persistent salt air eats standard galvanized steel caps faster than homeowners expect. A cap that looked fine five years ago may have rusted-out mesh that is now letting rain and animals into the flue.
- Cracked crowns over unused second fireplace flues. Almost every Dix Hills colonial has at least two wood-burning fireplaces, usually one in the formal living room and one in the family room. The family room flue gets used. The formal living room flue often goes years untouched, and a cracked crown above it lets rainwater mix with old creosote into a corrosive paste that destroys the clay liner.
- Undersized caps on multi-flue chimneys. A single-flue cap installed over a chimney built with two or three clay-tile flues leaves the other flues open to weather. We see this constantly when a previous contractor took a shortcut. Nor’easter-driven rain enters the uncapped flue, and first-degree creosote becomes a hardened third-degree glaze in a single wet season.
- Oil-to-gas conversion leftovers. As Dix Hills homeowners convert from oil to high-efficiency gas, the old furnace flue, sized for a big oil burner, becomes oversized for the new appliance. That oversized flue traps condensation, which drips back down onto the cap and crown, accelerating corrosion and cracking. A cap that worked fine for twenty years can fail within two years of a fuel conversion.

FAQs - Chimney Cap & Crown in Dix Hills
Most Dix Hills colonials built between the 1960s and 1980s were designed with one flue for the oil furnace and separate flues for each wood-burning fireplace, all sharing a single exterior chimney chase. Yes, both flues need their own caps. An uncapped second flue lets rain, leaves, and animals in, and that moisture mixes with creosote to create a corrosive acid that ruins the liner from the inside out. Call (516) 968-5380 and Wendell will assess both flues while he is up there.
Salt air accelerates corrosion on galvanized steel caps and speeds up mortar erosion on exposed crowns because the airborne salt deposits act as a mild abrasive and a chemical catalyst every time humidity rises. Dix Hills sits close enough to both Long Island Sound and the Great South Bay that this effect is real and measurable. A cap that would last twenty years in Melville might start rusting through in twelve to fifteen years here, and crowns spall faster. If you have not looked at your cap in five years, the salt has been working on it the whole time.
You may not need to replace the cap immediately, but you definitely need the whole crown-and-cap assembly inspected. The old oil furnace flue is now oversized for the high-efficiency gas unit, and that oversized flue traps condensation that drips back down and corrodes the cap and crown faster than before. In some cases the existing cap is still serviceable but needs resealing; in others the accelerated corrosion means replacement is the right call. Wendell will show you the camera footage and tell you the plain truth, not a sales pitch.
Yes, and it is a failure chain we see every winter. A cracked crown lets rainwater into the flue. The water mixes with creosote deposits, creating a slurry that breaks down the clay-tile liner. Over time, that deterioration lets heat and embers reach the masonry or wood framing that should be protected. The sequence is slow, but the result can be an intense chimney fire. If your crown has visible cracking, call (516) 968-5380 and get it sealed before the burning season starts.
Because the flue you never use is the one accumulating whatever the weather and the local raccoons leave in it. Neglected second flues in Dix Hills colonials routinely fill with nesting debris, leaves, and years of dry creosote that never gets swept because the fireplace never gets used. Then a nor’easter knocks out power for three days, you light that rarely-used fireplace out of necessity, and the flue you ignored becomes the one that ignites. Even an unused flue needs a proper cap and an occasional inspection. Call us for a full assessment, and remember: no trip charge for calls inside our service county.
Call Top Hat Chimney for Chimney Cap & Crown in Dix Hills
On Burrs Lane, we replaced a corroded single-flue cap with a custom Copperfield multi-flue cap after the original cap’s expanded metal mesh had rusted through from decades of salt air. The crown was spalled and had cracked mortar joints, so we rebuilt it with a flexible crown coating and straightened the damper, stopping water entry into both flues before sixth-degree creosote could harden inside the neglected family-room flue. That is the kind of problem we find when we show up, and it is the kind of problem we fix the right way the first time.
If you live in Dix Hills and your chimney cap is rusting, your crown is cracking, or you simply have not had either inspected in years, call Wendell and his crew at (516) 968-5380. You will get a live person, an honest assessment, and a firm price before any work begins. We serve Dix Hills and the surrounding towns with the same standard we have held since 1999: do the job right, show you the proof, and stand behind it in writing for 90 days.
