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 Ewing
Chimney liner installation and chimney rebuilds in Ewing typically run $1,800 to $6,500 depending on whether we’re dropping a stainless liner into an existing flue or rebuilding a spalling masonry stack from the roofline up. Most Ewing jobs are completed in a single visit once materials are staged, and we scope every flue with a Level-2 camera before quoting anything. Call (856) 388-5580 - a live person answers, even at 11 p.m. on a Sunday.
We’ve been working on Ewing chimneys for over 42 years, and the calls we get here are different from what we see in newer Mercer County townships. Ewing’s neighborhoods - from the post-war ranches along Parkway Avenue to the Capes near the College of New Jersey campus to the older homes pressing up against the Trenton line - share a common problem: original masonry chimneys built for oil, coal, or early gas systems, now venting modern appliances they were never designed to handle. Our Chimney Liner & Rebuild team knows these stacks. We know the shared-chase configuration that dominates Ewing’s 1950s-1970s housing stock. And we know how to fix them without selling you work you don’t need.
Dispatch and scheduling for Ewing are coordinated from our New York City office, but our crews live and work in Central New Jersey. That means we’re not driving down from North Jersey at 7 a.m. and charging you for the commute. We’re local.
Why Hearthstone Chimney Co. Is Ewing’s Preferred Chimney Liner & Rebuild Company
Ewing homeowners tend to stay put. They’ve been in the same ranch or Cape for twenty, thirty, sometimes forty years. They’ve had sweeps come and go. What they haven’t had is a company that shows them the inside of their own flue on a monitor, explains what they’re looking at in plain English, and puts the guarantee in writing before anyone lifts a trowel.
Our reputation in Ewing is built on that transparency. The 90-Day Done Right Promise - Krafted right, Every time, Your home first, Standing behind it - means if it’s not right, we make it right. No paperwork to dig up. No arguing. We answer the phone with a live person 24 hours a day, 7 days a week, because chimney problems don’t wait for business hours. Our technicians are background-checked, uniformed, and trained to complete most liner and rebuild jobs in a single visit with no-hassle upfront pricing. The number on the estimate is the number on the invoice.
We don’t chase every job. We chase every job done right. In Ewing, that means understanding the township’s specific housing stock - the shared flue chases, the coal-era conversions, the Delaware River moisture cycle - before we ever set a ladder against your brick.
Our Chimney Liner & Rebuild Services in Ewing
Stainless Steel Liner Installation
A stainless steel liner is the standard for Ewing’s gas and oil conversions - and for good reason. The original clay-tile flues in Ewing’s 1950s-1970s ranches and Capes were sized for furnace outputs that bear no resemblance to modern appliances. A stainless liner from DuraFlex or Olympia Chimney, correctly sized to your BTU load and dropped with a proper top plate and insulation, brings the flue into compliance with NJ Uniform Construction Code and eliminates the carbon monoxide backdraft risk that unlined or oversized flues create. In Ewing, where so many homes converted to gas in the 1980s and 1990s without relining, this is the most common fix we quote. And we quote it only after you see the camera footage yourself.
Flexible Liner Installation
Not every Ewing chimney runs straight. The older masonry in neighborhoods near the Trenton border - pre-1950 homes with offset flues or settled construction - sometimes needs a flexible liner that can navigate bends without breaking the draft. We use professional-grade flexible products from trusted manufacturers, sized to the appliance and installed with proper insulation to prevent condensation. Flexible liners are not a shortcut. They’re the right tool when the chimney geometry demands it. We scope first, measure second, and recommend third.
Liner Replacement
Ewing has its share of “already relined” chimneys that were relined wrong. We see this constantly: a furnace liner dropped in the 1990s at 5-inch diameter, then a wood-burning insert added in the 2000s without resizing, or a gas conversion that never updated the liner spec. The liner looks intact on a casual glance. It’s not. It’s the wrong liner for the wrong appliance, and it’s creating a code violation and a safety hazard simultaneously. Our camera inspection catches these mismatches. We document the diameter, the condition, and the appliance connection, then quote replacement with the correct specification - typically a stainless liner from Gelco or Copperfield, properly insulated and capped.
Partial Chimney Rebuild
The Delaware River valley moisture that Ewing sits in accelerates what Central New Jersey’s freeze-thaw cycle already does to mortar joints. Spalling brick faces. Cracked crowns. Failed flashing. A partial rebuild addresses the damage from the roofline up - new crown, rebuilt courses, proper counter-flashing, and a cap system that sheds water instead of trapping it. We don’t rebuild what doesn’t need rebuilding. The camera shows us what’s happening inside the flue; a physical inspection shows us what’s happening to the masonry. Both inform the scope. Both are documented with photos you keep.
Full Chimney Rebuild
When the stack is compromised below the roofline - structural cracking, leaning, or extensive spalling from years of water intrusion - a full rebuild is the only safe option. In Ewing’s older neighborhoods, particularly near the river and in the pre-1950 pockets near Trenton, we’ve rebuilt chimneys from the attic floor up, preserving the fireplace and firebox where possible and reconstructing the flue system with modern materials and proper clearances. It’s major work. We don’t minimize that. But we also don’t quote it unless the evidence supports it, and you’ll see that evidence before we talk numbers.

Trusted Brands We Service in Ewing
We don’t use builder-grade substitutes. Our Ewing jobs are built with professional-grade materials from manufacturers we trust: DuraFlex and Gelco for stainless and flexible liners, Olympia Chimney for caps and flashing systems, Famco for termination fittings, and Copperfield for specialty rebuild components. We stock common liner diameters and crown-forming materials locally, which means faster turnaround for Ewing homeowners and no waiting on back-ordered parts for standard installations. Every component is spec’d to the appliance, the flue, and the NJ code - not to what we happen to have on the truck.
Common Chimney Liner & Rebuild Problems We See in Ewing Homes
- Shared-chase cross-contamination. Ewing’s 1950s-1970s ranches and Capes were framed around a single masonry chase holding two flues - one fireplace, one furnace - so a shared stack is the township norm and cross-contamination between them is a routine diagnostic, not an exotic one. We scope both flues every time, because fixing one while ignoring the other leaves the problem intact.
- Clay-tile flues relined at furnace diameter, then an insert added without resizing. The liner is intact but wrong. The mismatch never shows without a camera. We find these in Ewing homes where owners installed wood-burning inserts into flues that were never designed or relined for solid-fuel appliances - a combination that is both a fire hazard and a near-automatic NJ code deficiency flag on home inspection reports.
- Third-degree creosote glazed inside a shared-chase fireplace flue, sold as “just needs a sweep.” No brush will touch glazed creosote. The fix is a liner, not a brushing. We’ve seen Ewing homeowners pay for three “sweeps” before someone finally scoped the flue and showed them the truth on camera.
- Mortar joint spalling and cracked brick faces from Delaware valley freeze-thaw. Ewing sits adjacent to the Delaware River valley, and the added atmospheric moisture from the river corridor intensifies Central New Jersey’s already punishing freeze-thaw cycle, accelerating mortar joint spalling and brick face deterioration on the older masonry chimneys that define the township’s housing stock. Dismissed as cosmetic until the crown and flashing fail and water starts tracking down the flue.
On a 1962 brick ranch off Lower Ferry Road, our tech scoped a shared chase and found the furnace flue venting into the same crown as a fireplace flue running a factory-built insert - heavy glazed, third-degree creosote on the tile, spalling mortar at the cap, and a smoke chamber never parged. We documented it all on camera with the homeowner watching the monitor, then rebuilt the crown, dropped a DuraFlex stainless liner sized to the insert, and wrapped the furnace flue with a correctly sized liner and new cap and flashing. Done right - and we stand behind it.

FAQs - Chimney Liner & Rebuild in Ewing
No. Each flue is a separate system with separate sizing, separate clearances, and often separate appliance connections. In Ewing’s shared-chase ranches and Capes, we quote each flue individually because one may need a liner while the other needs only a cap and crown repair. We scope both and explain what each requires. Call (856) 388-5580 for an exact quote - estimates are free.
Because the last sweep may not have run a camera, may have sized the liner to the wrong appliance, or may have been looking at a different problem entirely. We find mismatched liners in Ewing constantly - intact but wrong for the current appliance. Our recommendation is based on what the camera shows, what the appliance manual specifies, and what NJ code requires. Nothing less. If you want a second opinion on any written estimate, we’ll provide one at no charge.
Third-degree glazed creosote cannot be brushed out. No sweep can. In Ewing’s older fireplace flues, particularly where inserts were added to unlined clay tile, we find glazed deposits that have become part of the flue surface. Chemical treatment can sometimes loosen it, but the underlying problem - an unlined or improperly sized flue - remains. The permanent fix is a correctly sized stainless liner. We’ll show you the glaze on camera and explain why.
It depends on what the flag is for. In Ewing, inspection reports typically cite unlined flues, deteriorated mortar, or spalling brick - all visible from the exterior or detectable with a camera. A rebuild can mean anything from a new crown and top courses (partial) to reconstruction from the attic floor up (full). We review your inspection report, scope the flue ourselves, and tell you exactly what work addresses the specific deficiency. No more, no less. Photos you can see, a plain-English verdict.
Yes. Ewing’s proximity to the Delaware River valley adds atmospheric moisture that intensifies freeze-thaw damage to masonry. Water enters hairline cracks in summer, freezes and expands in winter, and spalls brick faces or opens mortar joints by spring. It’s not theoretical - we see it on Ewing chimneys every March. The moisture also accelerates corrosion on metal components and can worsen condensation in gas flues. Proper crowns, caps, and correctly lined flues are the defense. Call (856) 388-5580 and we’ll assess what your stack needs.
