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.
Trusted Chimney Liner & Rebuild for Ewing Homeowners
A chimney liner and rebuild in Ewing typically costs between $2,800 and $8,500 depending on whether you need a stainless steel liner replacement or a full masonry rebuild, and most jobs are completed in a single visit. Hearthstone Chimney Co. has been serving Ewing and surrounding Mercer County communities for over 42 years, and our Level-2 camera inspections give you photos you can see and a plain-English verdict before any work begins. Call (856) 388-5580 to speak with a live person, 24 hours a day, 7 days a week.
We’ve rebuilt chimneys in Ewing’s Parkside, Glendale, and Braeburn Heights neighborhoods, and we’ve replaced liners in the historic homes near The College of New Jersey and the newer construction off Scotch Road. The freeze-thaw cycles in Ewing’s climate, with temperatures swinging from single digits to the 90s across the seasons, take a toll on masonry that other regions simply don’t see. When mortar crumbles and liners crack, smoke and carbon monoxide can leak into living spaces. That’s not a scare tactic. That’s building science, and we’ve documented it hundreds of times with our camera systems.
Our background-checked, uniformed technicians arrive with professional-grade materials from DuraFlex, HeatShield, Gelco, Olympia Chimney, Famco, and Copperfield. We don’t use builder-grade substitutes, and we don’t recommend work you don’t need. Every estimate includes no-hassle upfront pricing - the number you see is the number on the invoice. And every job is backed by our 90-Day Done Right Promise in writing, no arguing: if it’s not right, we come back and make it right.
What Our Chimney Liner & Rebuild Service Includes
Stainless Steel Liner
A stainless steel liner is a corrugated or smooth metal tube inserted inside your existing flue to contain combustion gases and protect the masonry from heat and corrosion. In Ewing, we install stainless steel liners most often in homes built before 1940 with unlined brick chimneys, or where clay tile liners have cracked from decades of thermal cycling. Our technicians measure the flue precisely, select the correct gauge and alloy for your fuel type - wood, gas, or oil - and install the liner with proper insulation and top connections using Olympia Chimney and DuraFlex components rated for the application.

Flexible Liner
Flexible liners are corrugated stainless steel tubes that can navigate offset flues, chimney bends, and other irregularities that rigid liners cannot accommodate. We recommend flexible liners in Ewing’s older homes, particularly in the Hillwood Manor and Mountainview sections near Chimney Liner & Rebuild - Plainsboro territory, where chimneys often shift slightly over decades and no longer run perfectly straight. Our team sizes the liner using video inspection footage, pulls it through with controlled tension, and seals the top with a Gelco or Famco termination fitting that keeps water and animals out while maintaining proper draft.

Liner Replacement
Liner replacement becomes necessary when clay tiles flake, crack, or separate at the joints, creating gaps where heat and creosote can reach combustible framing. In Ewing, we see this most in homes that converted from oil to gas without updating the liner, since gas exhaust is more acidic and condenses at lower temperatures. We remove the damaged liner entirely, inspect the surrounding masonry with our camera system, and install a new stainless steel or HeatShield cerfractory liner sized to current NFPA 211 standards for your appliance.

Partial Rebuild
A partial rebuild addresses damaged sections of the chimney - typically the crown, several courses of brick above the roofline, or a deteriorated smoke chamber - without reconstructing the entire structure. Ewing’s exposure to nor’easter moisture and summer humidity accelerates spalling and mortar decay at the top, where the chimney takes the worst weather. We match existing brick and mortar color where possible, pour a new concrete crown with proper drip edges and slope, and seal the work with breathable water repellent so the repair lasts.

Full Chimney Rebuild
A full rebuild is required when the chimney structure is compromised through multiple elevations - leaning, extensive spalling, missing mortar, or internal collapse that threatens the stack’s stability. We’ve completed full rebuilds in Ewing on homes in the Parkway Village area and near Chimney Liner & Rebuild - Delaware River communities, where age and groundwater exposure combined to undermine foundations. Our masons dismantle the chimney course by course, salvage usable brick when appropriate, and rebuild to current code with proper footings, flue sizing, and clearances to combustibles, documented with photos at every stage.

Liner Repair
Liner repair with HeatShield cerfractory foam or similar systems can restore minor cracks and gaps in clay tile liners without full replacement, provided the damage is localized and the surrounding tiles are sound. We use this approach in Ewing when camera inspection shows hairline cracks or eroded mortar joints but no tile displacement or spalling. The process involves cleaning the flue, applying the cerfractory mixture with specialized foam plugs, and curing it to form a smooth, insulated surface that meets UL 1777 standards for zero-clearance applications.

Brands We Service for Chimney Liner & Rebuild
We’ve installed and serviced hundreds of Olympia Chimney stainless steel liner systems across Mercer County, including Ewing, Lawrence, and our Chimney Liner & Rebuild in Princeton and nearby Delaware River communities. Their smooth-wall liners and flex products handle the venting demands of modern high-efficiency appliances particularly well, and we stock common diameters and adapters so most installations don’t wait on parts.
Gelco termination caps and Famco top-sealing dampers are standard on our Ewing rebuilds and liner replacements. Gelco’s multi-flue caps with proper screen height keep raccoons and squirrels out while allowing sufficient airflow, and Famco’s cast-aluminum and stainless dampers seal tighter than original throat dampers, saving measurable heat loss in winter. Copperfield supplies many of our specialty firestop components, insulation sleeves, and access doors for chase enclosures. Whether your chimney currently has one of these brands or another make entirely, we can inspect it, source the correct parts, and complete the repair or rebuild to manufacturer specifications.
Signs You Need Chimney Liner & Rebuild Right Now
- White staining or efflorescence on exterior brick indicates water is moving through the masonry and dissolving salts, which means your liner or crown is no longer protecting the structure. In Ewing, we see this frequently on north-facing chimneys that stay damp through winter, and it always precedes spalling and mortar failure if not addressed.
- Flakes of clay tile in the firebox or cleanout mean your liner is deteriorating from the inside, creating gaps where combustion gases can escape into wall cavities. This is not a maintenance item you can defer - a compromised liner is a code violation and a documented fire hazard under NFPA 211.
- Smoke or odors entering the house during use suggests liner damage, improper sizing, or masonry leaks that are reversing draft under certain conditions. Ewing’s tight, energy-efficient homes are particularly susceptible to negative pressure problems that expose liner deficiencies you might not notice in a draftier structure.
- Visible cracks in the chimney crown or missing mortar joints allow water directly into the stack, where freeze-thaw cycling destroys brick from the inside out. A crown crack in October becomes a partial rebuild by March in our climate, and we’ve tracked this progression repeatedly in Ewing inspections.
- Rust stains on the chimney face or damper assembly signal that exhaust gases are condensing inside the flue instead of venting properly, usually because the liner is incorrectly sized for the appliance or has failed entirely. Gas appliances with oversized flues are especially prone to this, and the condensation contains acids that accelerate masonry decay.

How Much Does Chimney Liner & Rebuild Cost in Ewing?
A typical stainless steel liner installation in Ewing runs $2,800-$4,500 for a straightforward single-flue application, while a full chimney rebuild generally falls between $6,500 and $8,500 depending on height, accessibility, and whether the foundation requires repair - you can read more about how much Chimney Liner & Rebuild costs for your specific setup. Partial rebuilds and liner repairs with HeatShield cerfractory foam usually land in the $1,800-$3,200 range, and flexible liner installations for offset flues add $400-$800 to the base cost for the additional labor and specialized fittings.
Several factors move these numbers. The fuel type matters - oil and wood appliances require higher-grade alloys and more insulation than gas. The flue’s condition matters - a chimney with significant mortar loss or offset requires more preparation before the liner can be installed safely. Roof pitch and access matter; steep roofs in Ewing’s older neighborhoods like Wilburtha and Prospect Heights require additional safety setup. And the appliance itself matters - a fireplace insert with a direct connect needs different components than a freestanding wood stove or central furnace.
To avoid overpaying, get a Level-2 inspection with video documentation before accepting any major repair. We’ve provided free second opinions on written estimates from other companies in Ewing, and we’ve found cases where a full rebuild was recommended when a liner replacement would have solved the problem, or where a cheap liner was quoted that wouldn’t last five years in this climate. Our estimates include every component, all labor, and disposal - no line-item surprises when the invoice arrives.
Current standing offers include $50 off any repair over $250, a $89 Seasonal Tune-Up, and a permanent 5% Senior and Veteran discount. Call (856) 388-5580 for an exact quote - estimates are free, and you’ll speak with a live person, not a voicemail system.

Frequently Asked Questions - Chimney Liner & Rebuild in Ewing
Chimney liner and rebuild work restores the internal flue passage and external masonry structure that safely vent smoke and combustion gases from your fireplace, stove, or furnace to the outside. A liner is the protective sleeve inside the flue; a rebuild addresses damaged brick, mortar, crown, or foundation that threatens the chimney’s stability. Hearthstone Chimney Co. handles both, from single-flue liner replacement to complete masonry reconstruction, always starting with a camera inspection so you see exactly what needs attention.
Most liner installations and partial rebuilds are completed in a single day; full chimney rebuilds typically require two to three days depending on weather and curing times for mortar and crown concrete. Our background-checked, uniformed technicians arrive with the materials and tools needed for the scope, and we don’t leave until the work is finished and tested.
