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 Cleaning & Sweep Across Greenlawn
A chimney sweep in Greenlawn typically costs between $189 and $349, and most jobs are done in under two hours. That’s the honest range we quote on the phone before a single tool comes off the truck. If you live in Greenlawn and your fireplace smells damp, your cap is rusting through, or you can’t remember the last time anyone looked inside your flue, call Greenlawn Fireplace Services at (631) 502-3612. Wendell and his crew have worked these North Shore streets long enough to know exactly what the salt air does to a 1960s chimney. We’ll give you a straight answer, not a sales pitch, and we’ll show you the camera footage to prove it.
Why Top Hat Chimney Is Greenlawn’s Preferred Chimney Cleaning & Sweep Company
We’re a locally owned, owner-operated outfit, not a franchise that rotated in last spring. Wendell Pike founded Top Hat Chimney in 1999 and puts his name on the work. He runs into you again on Saturday at the Greenlawn hardware store, so he has every reason to do the job right the first time. Greenlawn homeowners have our published license number and our address; you know exactly who you’re dealing with before we ever knock on the door. When you call (631) 502-3612, a live person answers. Around the clock. It might be Wendell himself picking up. No voicemail box, no call center in another state.
Ask anyone on your street. Greenlawn is small enough that word travels. The reviews from Greenlawn customers tend to mention the same things: the price quoted on the phone is the price on the invoice, the sweep who shows up is background-checked and in uniform, and the work is backed by a 90-Day Done Right Promise in writing. If it’s not done right, one call brings us back at no charge. That’s not a slogan. It’s stamped on every job we complete in Greenlawn.
We also know the specific failure patterns on this side of Suffolk County. Our Chimney Cleaning & Sweep team sees the same issues over and over on the post-WWII Capes and ranches along Broadway, Pulaski Road, and the side streets off Cuba Hill Road: galvanized caps rusted through at the seam, crowns spalling from freeze-thaw, and clay flue tiles cracked decades before anyone noticed. That local knowledge means we know what to look for before we even climb the ladder.
Our Chimney Cleaning & Sweep Services in Greenlawn
Every Greenlawn home gets the same treatment: a camera inspection, a plain-English verdict, and an honest recommendation. Here’s what that looks like in practice for the services homeowners call us about most.
Level 1 Inspection
A Level 1 inspection is the standard check that happens alongside every sweep. In Greenlawn, we’re looking specifically for salt-air pitting on metal components, hairline cracks in the crown, and any sign that moisture has found its way into the firebox. Most Greenlawn homeowners get a Level 1 inspection once a year when we sweep. For a home half a mile from Long Island Sound, that interval isn’t a formality. It’s the earliest warning you’ll get before a cheap galvanized cap turns into a water problem.
Level 2 Inspection
A Level 2 inspection is a deeper look, and it’s what we recommend in Greenlawn any time a home changes hands, switches fuel sources, or shows signs of water intrusion. We run a camera through the entire flue and document every crack, gap, and spalled section on video. If you bought a 1962 ranch off Pulaski Road and have no record of the previous owner ever relining the chimney, a Level 2 inspection tells you exactly what you’re working with. The footage is yours to keep, and we go over it with you frame by frame so you can see what we see.
Creosote Removal
First-degree creosote is a brush job. Third-degree creosote is a glaze, and it’s a genuinely different problem. In Greenlawn’s older Capes, we regularly see third-degree glaze in chimneys that were used heavily with a fireplace insert or an old wood stove. Those tight, drafty flues cool the smoke too quickly, and the tar hardens into a shiny, acidic layer that a brush won’t touch. We treat it chemically and, in severe cases, recommend a more aggressive approach. Leaving it in place is how chimney fires start.
Soot Removal
Soot from oil combustion is acidic and greasy, and it clings to clay flue tiles in a way that wood soot doesn’t. Many Greenlawn homes switched from oil to gas years ago but never cleaned the old oil residue out of the chimney. That’s a problem, not just a cosmetic one. The acidic residue eats at the tile and the mortar joints, and the liner often ends up undersized for the gas appliance’s exhaust. We remove the old soot properly before assessing whether the liner is still doing its job. Our Greenlawn customers hear this from us more often than they expect, and it’s exactly the kind of thing a fast sweep-and-leave outfit misses.

Trusted Brands We Service in Greenlawn
We install and service components from Copperfield, DuraFlex, and HeatShield, and we stock common replacement parts so Greenlawn customers aren’t waiting on a distributor three weeks out. When we replace a corroded galvanized cap on a North Shore chimney, we’re putting on a stainless DuraFlex unit rated for coastal exposure. When a clay liner is cracked and leaking, Greenlawn Chimney Liner & Rebuild work using HeatShield resurfacing can often save the original masonry without a full teardown. We use what lasts in this environment, not what’s cheapest to order. Local parts availability and fast turnaround matter here because Greenlawn’s salt air doesn’t pause while you wait for a back-ordered part.
Common Chimney Cleaning & Sweep Problems We See in Greenlawn Homes
- Galvanized cap failure from coastal salt air. Original galvanized chimney caps on Greenlawn’s 1950s-1970s homes corrode at the seam within five to seven years of salt exposure. Once the seam opens, rain and salt-laden mist drip directly onto the damper and into the firebox. Replacing the cap early, before the water works its way into the smoke chamber brick, is a few hundred dollars. Waiting until the musty smell is a whole different job.
- Freeze-thaw spalling around the clay flue tile. Suffolk County winters average 30-40 frost events per season. When moisture has already found its way into the crown or mortar joints, each freeze cycle pushes the cracks wider. By the time a Greenlawn homeowner notices crumbling brick on the crown or bits of masonry in the yard, the damage is usually well underway. That’s why we push annual inspection even when you haven’t burned a fire all year. Chimneys break in the off-season too.
- Third-degree creosote glaze from tight, drafty flues. Greenlawn’s post-WWII Capes often have chimneys that were built for open fireplaces but later retrofitted with inserts or stoves. The flue is too small or too cool, smoke hangs around, and creosote condenses into a hard, glassy glaze. A routine brush won’t remove it. This isn’t a cosmetic issue; it’s the primary fuel source for a chimney fire.
- Oil-to-gas conversion residue still in the liner. This is one of the most common findings on Greenlawn jobs where the home switched from an oil-fired boiler to gas within the last two decades. The old oil soot is acidic and chemically incompatible with the new appliance’s exhaust, and Suffolk County inspectors specifically flag liners that were never cleaned before conversion. The fix starts with a proper sweep, then a camera check to see whether the liner is still sound or needs HeatShield resurfacing or a new liner.

FAQs - Chimney Cleaning & Sweep in Greenlawn
Once a year, burn or no burn. If you’re close enough to the water that your car shows salt haze in the winter, your chimney is taking the same bath. The galvanized cap on a Greenlawn chimney fails within five to seven years, and the only way to catch that failure before it becomes a bigger problem is to have eyes on it annually. A Level 1 inspection with your yearly sweep covers this. Call (631) 502-3612 and we’ll get you on the schedule before the next frost cycle.
Yes, and in Greenlawn this is one of the most important reasons to have us out. If the oil soot was never cleaned from the clay liner before the gas conversion, that acidic residue is still sitting in the flue, eating at the tile and mortar joints. The liner is also often undersized for gas exhaust. This is a Suffolk County code concern, not just a maintenance issue. We’ll sweep the old residue, run a camera through the flue, and tell you whether the liner needs resurfacing or replacement. Call (631) 502-3612 for a free estimate.
In our experience, it’s the galvanized chimney cap. Greenlawn’s coastal salt air eats through the seam within five to seven years, and once the cap fails, water gets onto the damper and into the firebox. Greenlawn Chimney Cap & Crown replacement with a stainless cap runs $225-$475 installed, and that usually solves the water intrusion if it’s caught early. If the cap has been rusted through for a season or two, you may also be looking at crown repair and possibly more. We’ll show you exactly what we found on camera before we recommend anything. Call (631) 502-3612 and we’ll take a look.
The cracking isn’t coming from heat; it’s coming from water and freeze-thaw cycling. Greenlawn’s clay flue tiles absorb moisture from salt air and rain, then freeze and expand through the winter. Each freeze cycle widens hairline cracks until they become structural. Heat was never required. If we find cracked tile sections on a Level 2 inspection, HeatShield resurfacing can often restore the liner without a full teardown. Call (631) 502-3612 and we’ll run the camera and show you what’s actually happening inside your flue.
It depends on what stage the creosote is in. First-degree creosote is a dry, sooty deposit and a standard sweep removes it. Third-degree creosote is a hard, shiny glaze, and a brush won’t move it. That requires chemical treatment and sometimes multiple visits. Greenlawn’s older Capes with inserts or wood stoves are prone to third-degree glaze because the flue runs too cool. We’ll determine what you’re dealing with during the sweep and show you before and after photos. Call (631) 502-3612 for an exact quote, and remember estimates are free.
Call (631) 502-3612 today and we’ll give you a firm price over the phone. Live person answers, day or night. If it’s Wendell, ask him about what the salt air did to that house on Maplewood Lane last fall. He’ll tell you the same thing he told the homeowner: your flue doesn’t care how the fire looks. It cares how it breathes.
