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.

Why Top Hat Chimney Is Greenlawn’s Preferred Chimney Cleaning & Sweep Company
Wendell Pike started Top Hat Chimney in 1999, and he still answers the phone himself half the time. That matters in a place like Greenlawn, where word travels down Broadway and across the Pulaski Road corridor faster than any ad campaign. Homeowners here have told us stories about national outfits that quoted one number on the phone, sent a stranger in a rented van, and then found “necessary” repairs that tripled the bill. We don’t work that way. You get the price up front, the name of the sweep who’ll show up, and a written 90-Day Done Right Promise on every single job: if it’s not right, one call brings Wendell and his crew back at no charge.
Our Greenlawn customers call us because we know this town’s chimneys specifically. The post-WWII Capes and split-levels off Broadway and around the side streets near the Greenlawn train station were mostly built with masonry chimneys sized for oil-fired boilers. A lot of those homes have since converted to gas, and that conversion changes how the flue behaves. We see it constantly. And because we’re local, we don’t treat your chimney like a one-off service call. We treat it like a 50-year-old masonry structure living in salt air, because that’s exactly what it is.
Our Chimney Cleaning & Sweep Services in Greenlawn
Every Greenlawn chimney gets more than a brush through the flue. We look at the whole system the way an old-timer looks at a foundation wall: where the water’s getting in, what’s already failed, and what’s going to fail next winter if it’s not addressed. Here’s what that means in practice.
Level 1 Inspection
A Level 1 inspection is the minimum standard whenever we clean a chimney. In Greenlawn, we include it on every job. We check the accessible portions of the flue, the firebox, the damper, and the exterior cap and crown from the roof. For a typical annual sweep, this runs $189 to $249. If you burn wood regularly through a Long Island winter, this is the inspection level you want once a year.
Level 2 Inspection
A Level 2 inspection involves a camera run through the entire flue, and in Greenlawn it’s the inspection we recommend most often. Here’s why: your chimney was likely built in the 1950s or 1960s for an oil-fired boiler, then converted to gas at some point. Gas appliances vent cooler exhaust than oil, which means condensation forms in a flue that’s now oversized. That condensate is acidic, and it eats clay tile liners from the inside. A Level 2 inspection runs $299 to $449 in Greenlawn, and it’s the only way to see liner spalling, cracked tiles, and the efflorescence damage before it becomes a structural problem.
Creosote Removal
Creosote builds up in stages. First-degree creosote is a brush job. Third-degree is a glaze. In Greenlawn homes near the Sound, the humid marine air can make creosote stickier and harder to remove, especially if your flue runs cold because it’s oversized for a gas appliance. We remove creosote with rotary brushes and chemical treatments when needed. A standard creosote removal as part of a sweep runs $189 to $329 in Greenlawn, depending on buildup and flue length. Catching it at the first stage is the difference between a $200 cleaning and a $2,000 liner job.
Soot Removal
Soot removal matters most for oil-fired systems, which many Greenlawn homes still have. Soot is acidic and corrosive, and it coats flue walls with the same destructive chemistry as the condensate we see in converted gas flues. We remove soot thoroughly, then inspect the flue with a camera to make sure what’s left behind is a clean, sound chimney. This service typically runs $189 to $279 in Greenlawn.

Trusted Brands We Service in Greenlawn
When a Greenlawn chimney needs components replaced, we use materials built to withstand Long Island Sound’s salt air. That means stainless steel, not galvanized, and liners from DuraFlex and Copperfield. We regularly install DuraFlex stainless steel liners in Greenlawn homes where the original clay liner has spalled beyond repair. For crown and cap work, we stock parts that fit the masonry chimneys common to this area, which means faster turnaround and no waiting on a part that was ordered from a warehouse three states away. The brands we service and install, including HeatShield and Gelco, are chosen because they hold up in coastal conditions, not because they’re the cheapest option on the shelf.
Common Chimney Cleaning & Sweep Problems We See in Greenlawn Homes
After 29 years of cleaning and inspecting chimneys in this part of Suffolk County, certain failures repeat themselves in Greenlawn homes. Here’s what we see most often, and what it means for your chimney.
- Corroded galvanized caps and flashing. Salt-laden air off Long Island Sound eats galvanized steel in five to seven years. Once a cap rusts through, water pours directly into the flue, rusts the damper, and attacks the crown. In Greenlawn, we recommend stainless steel caps as a replacement, and we check flashing whenever we’re on a roof.
- Spalling liners from gas conversion. An oil-era flue connected to a gas appliance produces acidic condensate that eats clay tile. The visible sign is white efflorescence bleeding through the brick face. By the time you see it outside, the liner is usually heavily damaged inside.
- Freeze-thaw damage to crowns. Suffolk County winters cycle above and below freezing dozens of times. Salt-weakened mortar absorbs water, that water expands when it freezes, and the crown cracks. The crack widens each year, and eventually the entire chimney crown needs rebuilding.
- Creosote buildup in cold, oversized flues. A flue that’s too large for the appliance it now vents runs cold, and cold flues collect creosote faster. In Greenlawn, that means homes converted from oil to gas often need more frequent cleaning than the oil-era schedule they were designed for.

FAQs – Chimney Cleaning & Sweep in Greenlawn
White streaking, called efflorescence, is a sign that acidic moisture is migrating through your chimney’s masonry. In Greenlawn specifically, this usually means your chimney’s oil-era flue liner has deteriorated and is now venting a gas appliance that produces acidic condensate. That condensate dissolves the lime in the mortar and wicks through the brick as white minerals. A Level 2 camera inspection will confirm the condition of the liner. If you’re seeing streaking on your Greenlawn chimney, call (631) 318-8656 for an inspection before the damage spreads.
We recommend every Greenlawn chimney be inspected annually, and that’s a higher bar than some inland Suffolk communities need. The salt air off Long Island Sound shortens the life of flashing, caps, and mortar joints measurably. An annual inspection catches corroded galvanized components before they let water into the flue. Your flue doesn’t care how the fire looks. It cares how it breathes. And in salt air, it needs checking every year, burn or no burn.
Yes, significantly. A Greenlawn home built for oil heat typically has a masonry flue that’s now oversized for its gas appliance. That oversized flue runs cooler, and the cooling exhaust produces acidic condensate that attacks the clay liner. We see spalled liners, blocked flues, and exterior efflorescence more often in converted Greenlawn homes than in any other housing type we service. The camera footage and a plain-English verdict, every time, no exceptions. Call (631) 318-8656 to schedule an inspection, and if a liner issue is caught early, a DuraFlex retrofit can save you thousands in masonry repair down the road.
The chimney cap and the flashing. Galvanized steel corrodes within five to seven years in Greenlawn’s salt-laden air, and once the cap rusts through, water gets in. That water spalls the crown and starts the freeze-thaw cycle that cracks the masonry. If your cap is more than a few years old, or if you see rust streaking down the crown, call (631) 318-8656. We’ll replace it with stainless steel and check the flashing while we’re up there.
Yes. Greenlawn’s humidity from Long Island Sound makes creosote stickier, and the oversized flues common in this town’s converted oil-to-gas homes run colder, which means creosote deposits faster and harder. The combination of marine humidity and cold flue walls is a recipe for third-degree glazed creosote, which no brush alone will remove. We use rotary tools and chemical treatments when needed, and we always follow with a camera inspection to confirm the flue is clean. Catch it early and you’re paying for a sweep. Let it go and you’re paying for a liner. Call (631) 318-8656 for an exact quote, estimates are free.
