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 Cleaning & Sweep Across Clark
A chimney sweep in Clark typically costs between $189 and $289 for a standard fireplace cleaning with a Level 1 inspection, and most jobs are done in under two hours.

Why Top Hat Chimney Is Clark’s Preferred Chimney Cleaning & Sweep Company
Wendell Pike started Top Hat Chimney in 1999, and he still puts his name on every job. That means something in Clark. Homeowners here have told us stories about national outfits quoting one number on the phone, then sending a stranger who tacks on “unexpected masonry work” before the first brush goes up. We don’t do that. You get an upfront price, a background-checked sweep in uniform who actually knows cape cods from split-levels, and a 90-Day Done Right Promise in writing. If it’s not right, one call brings us back at no charge.
Ask anyone on your street. The houses along Valley Road and up toward the Cranford line have the same aging brick chimneys, the same oil-to-gas conversion headaches, and the same need for a sweep who understands how Union County weather beats on a chimney crown all winter. Our Chimney Cleaning & Sweep team has pulled more first-degree creosote out of Clark flues than we can count, and we’ve seen exactly how freeze-thaw cycles crack these 60-year-old crowns open. When you call, a live person answers. Twenty-four hours a day, seven days a week. Sometimes that person is Wendell himself.
Our Chimney Cleaning & Sweep Services in Clark
Level 1 Inspection
Every standard sweep in Clark includes a Level 1 inspection, per NJ code, and that’s exactly what it should be: a visual check of the firebox, flue, damper, and exterior chase for anything that has changed since the last cleaning. On a mid-century Clark home with a single chase serving both a fireplace and a converted gas furnace, we’re looking specifically at clearances, connector pipe condition, and whether the original clay tile liner is doing anything it shouldn’t be. It usually takes about 45 minutes on top of the sweep itself.

Level 2 Inspection
Clark homes that underwent an oil-to-gas conversion during the 1990s or 2000s are the classic case for a Level 2 inspection. This is a camera scan of the entire interior of the flue, from the firebox up to the cap, and it is the only way to see what a clay tile liner looks like after years of condensation from cool gas exhaust. When you bought your house, the home inspector likely never looked inside the flue. A Level 2 catches what an eyeball cannot. We recommend one whenever there has been a conversion, a storm that displaced the cap, or any sign of water below the chase. Every Clark homeowner gets the camera footage and a plain-English verdict. No exceptions.

Creosote Removal
Creosote in Clark breaks into two camps. First-degree creosote is dry, flaky soot that brushes out clean. That’s most of what we see in fireplaces used a handful of times each winter. But if a chimney cap got knocked loose during a nor’easter and rain sat in the flue, or if the fireplace burned unseasoned wood for a few years, that creosote has baked into a hard, gummy second-degree glaze. It does not come out with a standard brush, and forcing it just scores the liner. We use the right mechanical tools for the grade we actually see, not the grade the phone estimate assumed.

Soot Removal
Soot in a Clark flue is different from creosote. It’s the loose, black powdery stuff that clings to the smoke chamber and damper, and it comes from the cooler upper flue where exhaust slows down. It is also exactly what a gas furnace can push into a shared chase when the flue is oversized and draft-poor. Soot removal is a standard part of our annual sweep. It keeps the damper from seizing and keeps that first-fire smell from filling the living room in November.

Trusted Brands We Service in Clark
When a Clark chimney needs more than a sweep, our Clark Fireplace Services team installs and services products from DuraFlex, HeatShield, Famco, and Copperfield, among others. HeatShield and DuraFlex come up most often here because Clark’s oil-to-gas conversions almost always require relining. The typical 8-inch clay tile flue that once handled an oil-fired furnace is far too large for a modern gas appliance, and a properly sized stainless liner is the fix. We keep common copper and cap parts in the truck so a displaced or rusted-out Clark cap doesn’t mean booking a second trip. One visit, and most repairs are done.
Common Chimney Cleaning & Sweep Problems We See in Clark Homes
- Freeze-thaw spalling on original brick. Union County winters hover around 32°F for weeks at a time. Water gets into micro-cracks in the brick face, freezes, expands, and pops the brick’s surface off. In Clark’s 1950s and 60s chimneys, this is not a cosmetic issue. It opens the chase to water intrusion that shows up as a ceiling stain near the fireplace.
- Oversized clay flues pushing back against gas conversion. This is the Clark problem. The original 8-inch flue was built for an oil burner that produced hot, dry exhaust. A modern high-efficiency gas furnace produces cool, wet vapor that condenses inside that big clay tube, running acidic water down into the smoke chamber and corroding the damper.
- Cracked crowns and failed flashing after nor’easters. Clark sits in the nor’easter track. Wind-driven rain hits the top of the chimney horizontally and finds every hairline crack in the crown. Then it runs down into the gap between the flashing and the brick. We’ve seen homeowners scrub a ceiling stain for months before realizing the water was coming in through the chimney, not the roof.
- Second-degree creosote glaze after a displaced cap. A cap knocked loose during a storm lets rain run straight down the flue. Wet creosote baked over repeated fires becomes a hard, tar-like glaze that clings to the liner. It’s a fire hazard, and it cannot be brushed out with a standard sweep. It has to be broken up with mechanical tools.
Pricing for Chimney Cleaning & Sweep in Clark, NJ
A standard chimney cleaning and sweep in Clark, including a Level 1 inspection, runs $189 to $289 for a fireplace that has been maintained annually. First-time cleanings after years of neglect run higher, typically $299 to $389, because the creosote load is heavier and the job takes longer. A Level 2 camera inspection adds $150 to $250 depending on the chase height and liner condition. Crown sealing and minor flashing work typically falls between $225 and $400. Relining is more involved, and the price depends on the flue’s length and the liner’s diameter; a DuraFlex or HeatShield liner for a two-story Clark colonial commonly runs $1,800 to $3,200 installed. We offer $40 off any repair over $200, a free second opinion on any written estimate, and a 10% discount for seniors and veterans. Call (848) 331-2638 and you’ll get an exact quote before we book anything, and that number is the number on the invoice.

FAQs - Chimney Cleaning & Sweep in Clark
Because in Clark, the fireplace flue often shares a chase with a furnace and water heater, and nearly every home has had an oil-to-gas conversion that left the flue oversized. A fireplace that sits unused still gets exposed to whatever condensation, acidic vapor, or water intrusion is happening in the rest of the chase. A Level 2 camera inspection shows what is actually happening inside the liner, which is something no visual check can do. Call (848) 331-2638 to schedule one. Free estimate, camera footage included.
Look for a thin, white or gray coating on the outside of the brick below our Chimney Cap & Crown in Clark; that’s efflorescence caused by water moving through the masonry. You may also see hairline cracks in the crown itself, loose or missing mortar in the top few courses, or a damp smell near the fireplace after heavy rain. All of these point to freeze-thaw damage. If you see any of them, call us before the next hard freeze. A crown seal now is far cheaper than repointing the top half of the chimney later.
No. A chimney cleaning removes soot and creosote from the inside of the flue. A ceiling stain means water is coming in around the chimney chase, usually through failed flashing or a cracked crown. That’s a repair issue, not a cleaning issue. But a sweep is the first step because it lets us inspect the chase from the inside and pinpoint where the water is entering. We’ll tell you plainly if the repair can wait or needs doing before the next nor’easter.
First-degree creosote that has been reheated and compressed into a hard, flaky scale that stubbornly clings to the upper flue. If the cap ever sat displaced for a season, it can graduate into second-degree glaze. In a Clark fireplace that has burned four or five winters of fires without a sweep, this is common, and it’s exactly what raises chimney-fire risk. It comes out, but it takes longer and costs a bit more than an annual maintenance cleaning. Call (848) 331-2638 for an estimate. Better to get it out now than to find out about it during a fire.
Because the flue is likely oversized for the furnace. Clark’s original clay tile flues were built for oil-fired burners, and when the furnace was converted to gas, the liner was often left at 8 inches. Gas exhaust is cooler than oil exhaust and moves slower in that big flue, so it condenses and loses draft. A sweep can remove soot and obstruction, but it cannot fix the size mismatch. That usually requires our Chimney Liner & Rebuild in Clark with a properly sized stainless liner. We’ll show you the camera footage before recommending anything, and we’ll tell you if it can safely wait. Call (848) 331-2638 for a free estimate.
