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 Liner & Rebuild Across Clark
Chimney liner replacement in Clark, NJ typically runs $2,800-$5,400 for a stainless steel install, and a full rebuild starts around $6,000 depending on how much of the chase is compromised. Most Clark homes were built between 1950 and 1975 with original clay tile liners sized for oil-fired furnaces, and nearly all of them now run natural gas through flues that are too big for the job. That mismatch is the single biggest chimney problem we see in Clark, and it’s one a sweep can spot in the first ten minutes of an inspection.
Wendell Pike started Top Hat Chimney in 1999, and he’s been inside more Clark chimneys than he can count. If you’re off Westfield Avenue, over by Valley Road, or tucked into the neighborhoods around Lake Avenue, we know what your chimney looked like when it was built and what’s likely wrong with it now. Call (848) 331-2638 and a live person answers, day or night. It might be Wendell himself.
Why Top Hat Chimney Is Clark’s Preferred Chimney Liner & Rebuild Company
We’re locally owned and owner-operated. The sweep who shows up at your door is someone Wendell trained and trusts, and Wendell puts his name on the work. He has to run into you again at the ShopRite on Central Avenue, so the job has to be right the first time. Every job we finish comes with a 90-Day Done Right Promise in writing. If it’s not done right, one call brings the crew back.
Clark homeowners have told us the same story enough times that we can finish their sentences. A national outfit quoted one price over the phone, sent a stranger, and the number changed once the ladder went up. We don’t work that way.

Background-checked, uniformed, and we answer the phone around the clock. No call center.

Our Chimney Liner & Rebuild Services in Clark
Stainless Steel Liner
For a Clark home converted from oil to gas, the right fix is almost always a stainless steel liner sized to the new appliance, not the old boiler. An 8-inch clay tile flue that once handled a 140,000 BTU oil burner runs too cool and too slow with a modern 80,000 BTU gas furnace. Exhaust condenses before it exits, and that acidic condensation eats the tile from the inside. We install DuraFlex stainless liners matched to the exact flue diameter and BTU rating of your current equipment, bringing the chimney into compliance with current NJ fuel-gas code and restoring proper draft.
Flexible Liner
Flexible stainless liners make sense when your Clark chimney has a slight offset, which is common in the split-levels and Capes built during the 1960s where the flue jogs to dodge a beam. A rigid liner can’t make that bend without carving into the brick, and no one in Clark wants their chimney opened up for that. We pull the flexible liner through, insulate as needed, and anchor a proper cap on top. It’s a cleaner install, less disruption, and it drafts better than the cracked tile it replaces.
Liner Replacement
If we camera an existing liner and find cracked flue tiles, spalled clay, or gaps at the mortar joints between sections, the liner has to come out. No amount of patching fixes a broken liner. In Clark we see a lot of liners that were “fine” when the house converted to gas twenty years ago and never got sized down. The gas appliance ran on borrowed time, and now the tile is glazed, cracked, or both. We replace with a properly sized stainless liner and give you the camera footage to prove what was in there and what’s in there now. The camera footage and a plain-English verdict, every time, no exceptions.
Partial Rebuild
Not every Clark chimney needs to come down to the footings. When freeze-thaw cycles have popped a few brick faces off the crown, or when the top eight to ten courses are spalling but the rest of the stack still rings sound, a partial rebuild is the honest answer. We remove the damaged brick, rebuild the top section with matched material, pour a new crown, and install a proper cap. You get another fifteen to twenty years without paying for a full teardown. And if a partial rebuild isn’t safe, we’ll tell you that plainly instead of selling you something that won’t hold.

Trusted Brands We Service in Clark
We install and stand behind liners and components from manufacturers we’ve worked with for years, including DuraFlex, Gelco, and Olympia Chimney. Because we’re working Clark chimneys all week, we stock common liner diameters and cap sizes locally, which means we aren’t waiting on a freight truck to get your job started. If you have an existing liner from Famco or Copperfield, we service those too. When you call a national chain, the tech may have never touched the brand in your chimney. Wendell has.
Common Chimney Liner & Rebuild Problems We See in Clark Homes
- Oil-to-gas conversion without a reline. Nearly every Clark home built between 1950 and 1975 originally burned oil. The original 8-inch clay tile flue is far too large for a modern gas furnace, so exhaust cools before it exits, condenses, and the acidic byproduct eats the liner from the inside. This voids the furnace warranty and violates current NJ fuel-gas code.
- Freeze-thaw crown cracking. Union County winters cycle around 32°F from December through March. Water sits in the hairline cracks of a 1960s crown, freezes, expands, and pops the mortar joints wider every season. If the crown stays cracked and unsealed, water runs behind the liner and into the chase where your furnace and water heater flues share the same cavity.
- Wind-driven rain from nor’easters. Clark sits in the nor’easter track. Rain driven sideways into a cracked crown or a displaced cap saturates the brick and the liner cavity. Homeowners often find the first sign as a brown ceiling stain on the second floor under a flashing point, and by then the damage has been working for a season or two.
- Single chase serving three appliances. It’s common in Clark to find one chimney chase carrying a fireplace flue, a furnace flue, and a water heater flue. When the liner fails, it’s not isolated. Draft interference between those flues gets worse as the liner degrades, and any relining work has to account for the whole chase, not just one flue.
Pricing for Chimney Liner & Rebuild in Clark, NJ
A stainless steel liner replacement on a Clark home usually lands between $2,800 and $4,200 depending on flue height, access, and whether we’re insulating around the liner. For a flexible liner with a moderate offset, expect $3,000-$4,600. A partial rebuild of the top courses with a new crown and cap typically runs $1,800-$3,400. A full chimney teardown and rebuild in Clark starts at $6,000 on the low end and can reach $12,000 or more if the firebox, smoke chamber, and flue all need work, or if the chimney is tied into structural framing.
What moves the number is access: a straight two-story chimney with a walkable roof costs less than a split-level where the stack sits in a tight valley. Brick matching matters too. Clark’s 1960s brick stock is still available from local yards, but the blend costs more than new common brick. Before you commit to anything, call us for a free estimate. We give the price before work starts, and it won’t change at the door. We also offer $40 off any repair over $200 and a free second opinion on any written estimate from a competitor.

FAQs - Chimney Liner & Rebuild in Clark
You check the liner diameter, and you check it with a camera. If your home was built before the mid-1970s and converted to gas, the odds are high the original 8-inch clay tile was never swapped for a properly sized stainless liner. Pull the furnace or water heater flue cap and look, or better yet have us camera the flue. A liner that’s too big for a gas appliance leaves a visible pattern of acidic condensation at the tile joints. If you can’t tell by eye, we can. Call (848) 331-2638 and we’ll give you a straight answer and photos to back it up.
Clark’s freeze-thaw cycles are why the patch fails. As long as water sits in the crown’s deeper cracks and expands each winter, a thin patch will keep spalling off. If the crown is solid but cracked, a proper rebuild of the crown alone, with the right mix and a poured edge that sheds water, usually solves it for years. If the top courses of brick are also spalling or the mortar joints below are popping, then the top section may need a partial rebuild instead. We’ll tell you which one you actually need, and we’ll show you the damage before you pay for the fix.
A failed chimney liner can absolutely cause a second-floor ceiling stain, and in Clark it’s often mistaken for a roof leak. Water that gets behind a cracked liner is trapped in the flue cavity, and when it migrates out at a flashing point or mortar joint, it shows up as a stain under the roofline. Before you replace shingles, have the chimney inspected. The camera footage and a plain-English verdict, every time, no exceptions.
Most Clark colonials built between 1955 and 1975 need a 5-inch or 5.5-inch stainless liner for a gas furnace and a 6-inch liner if the water heater shares the flue. The old oil-era 8-inch tile was sized to move a lot of hot air fast. Gas exhaust is cooler and wetter, and it needs a smaller cross-section to keep velocity up and prevent condensation. We calculate the exact diameter from the BTU rating of the current appliance, not from what was there originally. That detail is the difference between a liner that lasts twenty years and one that rots in five.
Look at the brick, not just the flue. If the brick faces are tight, the mortar is sound, and only the liner and crown are compromised, you don’t need a rebuild. If the stack has visible spalling, if the mortar joints are eroded deep enough to pick out with your finger, or if the chimney leans even slightly, a rebuild is on the table. We won’t recommend a full rebuild unless the integrity of the masonry demands it. Walk away from anyone who tells you otherwise before they’ve even seen the chimney.
If you live in Clark and you’re staring at a cracked crown, a ceiling stain, or a furnace that never drafts quite right, call us at (848) 331-2638. We’ll come out, camera the flue, and give you the truth about what needs doing now and what can wait. Free estimates, no pressure, and the same face you’ll see in town next week.
