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 Hillside
Chimney liner replacement and partial rebuilds in Hillside typically run $1,800-$4,500 depending on flue count, access, and whether the stack is shared between two units. Most jobs we book in Hillside are completed in a single visit once materials are staged. Call (908) 923-3159 and a live person will pick up, 24 hours a day.
We’ve been working on Hillside’s brick housing stock for over 42 years. We know the semi-detached colonials off Hillside Avenue, the row houses near the Elizabeth border, and the cape cods tucked behind Liberty Avenue. These aren’t theoretical buildings to us. Our dispatch is coordinated from our New York City office, but our crews are in Union County every week, and we understand the access constraints of tight driveways, shared driveways, and party-wall roofs where two downspouts sit three feet apart.
Why Hearthstone Chimney Co. Is Hillside’s Preferred Chimney Liner & Rebuild Company
Hillside homeowners call us because we’ve seen their exact chimney before. The 1920s brick semi-detached with the original clay flue tiles. The 1940s cape cod that was converted from oil to gas in the 1990s and now vents a high-efficiency furnace into a flue built for a sooty oil burner. The three-family rental on a subdivided lot where one chimney stack serves two or three separate leases.
Our Level 2 camera inspections end with photos you can see and a plain-English verdict. No jargon, no scare tactics. If your liner has five years left, we’ll say so. If it’s cracked and leaking carbon monoxide into your neighbor’s unit, we’ll document it, explain why, and show you the image. The 90-Day Done Right Promise backs every job in writing. If it’s not right, we make it right. No paperwork to dig up, no arguing.
Calls are answered by a live person, 24/7. Not a callback queue. Not an app. Our technicians are background-checked, uniformed, and carry the materials to finish most Hillside liner and rebuild jobs in one visit. No-hassle upfront pricing means the number on the estimate is the number on the invoice.
Our Chimney Liner & Rebuild Services in Hillside
Stainless Steel Liner Installation
A stainless steel liner is the right fix for most Hillside homes with deteriorated clay flue tiles, especially in shared party-wall stacks where one flue has failed but the adjacent unit is still active. We use DuraFlex and Olympia Chimney stainless systems, sized precisely to the appliance or appliances being vented. In Hillside’s dense blocks, proper sizing matters more than in detached homes: an undersized liner on a furnace and water heater combo will backdraft; an oversized liner on a converted gas system will condense and rot the mortar from the inside. We measure, we calculate, we install. Done right, and we stand behind it.
Flexible Liner Installation
Flexible liners from DuraFlex solve the access problem that comes with Hillside’s older masonry. Many of these chimneys have offsets, corbels, or tight turns where a rigid liner simply won’t pass. A flexible system navigates those bends while still delivering the full stainless rating. We see this constantly in Hillside’s row houses, where the flue may jog around a structural member from the 1930s. Our techs run the camera first, map the path, and specify the right flexible product for the geometry and the fuel type. Most flexible liner jobs in Hillside run $2,200-$3,800 for a single-flue residential installation.
Liner Replacement
Full liner replacement becomes necessary when clay tiles are spalling, mortar joints between tiles have eroded, or a Level 2 inspection finds gaps that allow combustion gases into the chimney cavity. In Hillside’s shared stacks, we often find that one side’s liner failed years ago and the homeowner never knew because the symptoms showed up in the neighbor’s unit first: a faint exhaust smell, a CO detector chirp, a draft that never quite worked right. We replace the liner, rebuild the smoke chamber if needed, and verify draft on every appliance separately. Photos you can see, a plain-English verdict.
Partial Rebuild
Not every failing chimney needs to come down. A partial rebuild targets the damaged section: the crown, the top courses of brick, the flue opening, the wash. In Hillside, we perform partial rebuilds on party-wall stacks where the upper courses have taken decades of freeze-thaw but the lower structure is sound. We match the existing brick profile, pour a new concrete crown with proper slope and overhang, and install a cap that keeps birds and water out of both flues. A typical partial rebuild in Hillside runs $1,800-$3,200. If the damage is limited to the crown and cap, we may be able to restore rather than rebuild, and we’ll tell you straight which path saves money without cutting corners.

Trusted Brands We Service in Hillside
We work exclusively with professional-grade materials: DuraFlex and Olympia Chimney for stainless and flexible liners, HeatShield for cerfractory flue resurfacing, and Gelco for caps and screening. We stock common diameters and fittings locally, so Hillside jobs don’t wait two weeks for a part to ship. When a Hillside landlord calls on a Friday because a tenant’s CO detector went off and the inspection revealed a cracked liner, we can often have the right DuraFlex kit on the truck Monday morning. No builder-grade substitutes. The material has to last as long as the masonry it’s protecting.
Common Chimney Liner & Rebuild Problems We See in Hillside Homes
- Carbon monoxide migration through party-wall cracks. In Hillside’s attached housing, a cracked flue liner on one side of a shared stack can vent exhaust into the chimney cavity, where it finds gaps in the wythe separation and enters the neighboring unit. The failure is invisible until a Level 2 inspection is run on both sides.
- Condensation damage from oversized oil-to-gas conversions. Hillside’s 1920-1955 brick homes were built for hefty oil furnaces. When a modern gas appliance vents into that same large flue, the gases cool too quickly, condense on the liner walls, and accelerate mortar erosion and spalling on a cycle of every few years rather than every decade-plus.
- Shared backdraft from a blocked neighbor flue. In the densest Hillside blocks, a single exterior stack serves two addresses with flues stacked side by side. A bird nest or broken cap on one flue can disrupt draft on both, creating a liability that stalls repairs until two owners or leases agree on access.
- Spalling clay tiles in 70-100-year-old original liners. Hillside’s housing stock is now reaching the end of its original clay flue tile lifespan. The tiles flake, crack, and shift, opening gaps that collect creosote or allow direct gas leakage into the brick chase.

FAQs - Chimney Liner & Rebuild in Hillside
Each owner is responsible for maintaining their own flue and appliance, but the shared brick chase and any structural compromise affects both parties. We recommend coordinating a joint Level 2 inspection so both flues are documented, both owners understand the condition of the separation between flues, and any repair scope is clear before work begins. Call (908) 923-3159 and we’ll explain how we handle two-party estimates with no pressure on either side.
Original clay flue tiles in Hillside’s housing stock are now 70-100 years old, past their designed lifespan, and the mid-century conversion from oil to gas heating left many flues oversized for modern appliances. The resulting condensation accelerates mortar erosion and spalling on a shortened cycle. A newer home with a properly sized stainless liner installed from day one simply doesn’t face these stacked failure modes. We inspect, we document, we tell you honestly whether this year is the year or if you have two seasons left.
Yes. In Hillside’s dual-address stacks, a blockage on one flue can disrupt the pressure balance across the entire chase, causing backdraft or spillage from either flue. We’ve found nests, broken caps, and even collapsed liner sections on one side that were creating draft problems the neighbor had been chasing for months. Our Level 2 inspection covers the full chase, not just your flue, because the physics don’t respect property lines.
We inspect both flues with a camera, document the condition of the wythe separation between them, size the new liner to your specific appliance, drop it from the top, connect it at the appliance collar, seal the top with a proper termination, and verify draft on each appliance independently. If the neighboring flue is also compromised, we can price both or sequence the work. Most single-flue replacements in Hillside are completed in one day once materials are on site. Call (908) 923-3159 for a free estimate.
Annually, per NFPA 211, and we believe shared stacks in Hillside’s dense housing merit the Level 2 camera inspection every two to three years even if no problems are apparent. The hidden nature of party-wall gas migration means a visual check from the hearth or roof won’t catch what a camera will. The $250-$350 inspection cost is modest protection against a carbon monoxide event that could affect two households. Schedule yours at (908) 923-3159.
On a semi-detached colonial off Hillside Avenue near the Irvington line, we found a 1940s clay flue liner spalling in the left stack while the right unit’s furnace still vented into the same chase; a bird nest had capped the right flue, forcing exhaust toward the neighbor’s damper. Our tech coordinated with both owners, ran a Level 2 inspection on both sides, dropped a DuraFlex stainless liner on the affected unit, rebuilt the chimney crown and cap, and confirmed draft on each appliance separately. That’s the kind of job we do in Hillside. No shortcuts. No surprises on the bill. Photos you can see, a plain-English verdict. Done right, and we stand behind it.
If your Hillside chimney needs liner work, a partial rebuild, or just an honest inspection to know where you stand, call (908) 923-3159. A live person answers, 24 hours a day. Estimates are free. The 90-Day Done Right Promise covers every job in writing.
