Fast, Reliable Chimney Liner & Rebuild Across Union
Chimney liner replacement and rebuild work in Union, NJ typically runs $1,800-$4,500 depending on scope, and most jobs are completed in a single day with no-hassle upfront pricing. If your chimney was built between the 1940s and 1970s - which describes most homes in Union - the original clay-tile liner is likely deteriorating from decades of gas-condensation exposure, and waiting only raises the repair cost.
We’ve been working on chimneys along Morris Avenue, Stuyvesant Avenue, and the residential streets off Vauxhall Road for over 42 years. Union’s housing stock is familiar territory for our technicians. We know the Cape Cods near Connecticut Farms, the colonials tucked behind Kean University, and the brick masonry chimneys that vent everything from original oil-conversion furnaces to modern gas inserts. When you call (844) 803-1545, a live person answers - day or night - and we can usually have a uniformed technician at your door within 24 hours.
Why Hearthstone Chimney Co. Is Union’s Preferred Chimney Liner & Rebuild Company
Union homeowners tend to stay put. They’ve raised families in the same post-war colonial for thirty years, and they’re not interested in a contractor who treats their chimney like a commodity. Our reputation here was built one job at a time - documented with photos, explained in plain English, and backed by the 90-Day Done Right Promise in writing.
We’ve completed liner replacements and partial rebuilds from the quiet streets near Union Village to the busier corridors around Route 22. Our customers in 07083 call back when they need us again, and they recommend us to neighbors. That’s how a local business survives 42 years.
Response time matters when you’re smelling smoke in the living room or seeing brick flakes in the driveway. From our dispatch, Union is a straight shot - we’re typically on-site within hours for urgent calls, and we schedule routine inspections within a day or two. No callback queues, no app-based scheduling, no wondering if someone will show.
Our technicians carry the brands Union chimneys actually need - HeatShield, Gelco, Olympia Chimney - and they know the local code requirements for Essex and Union County multi-appliance venting. When a chimney on Salem Road needs a liner sized for both a furnace and a fireplace, or when a Vauxhall Road homeowner discovers their abandoned flue was never properly capped after a direct-vent upgrade, our Chimney Cap & Crown in Union team has handled it before. We’ll be there when we say.
Our Chimney Liner & Rebuild Services in Union
Stainless Steel Liner Installation
A stainless steel liner is the right choice for most Union chimneys that vent gas or oil appliances, and our Fireplace Services in Union include expert sizing and installation. The original clay tiles in these 1940s-1960s homes were never designed to handle the acidic condensation produced by modern high-efficiency equipment. We install DuraFlex and Olympia Chimney stainless liners sized precisely for your appliance combination, whether you’re venting a furnace, water heater, or both through the same flue. Most stainless installations in Union run $2,200-$3,800 and are completed in one day with the firebox fully protected and the work area cleaned before we leave.
Flexible Liner Installation
Union’s older chimneys often have offset flues, hidden bends, or narrow passages that rigid pipe simply won’t navigate - especially in the Cape Cods near Connecticut Farms where construction shortcuts were common. A flexible liner from our Chimney Liner & Rebuild team threads through these obstacles without dismantling the chimney structure. We see this need frequently on homes where a previous owner installed a wood stove insert without proper venting. Flexible liner jobs in Union typically range from $1,800-$3,200.
Liner Replacement
When a clay-tile liner has cracked, shifted, or deteriorated to the point of leaking combustion gases into the home, replacement is not optional - it’s a safety issue. In Union’s freeze-thaw climate, water infiltration through damaged mortar joints accelerates liner failure every winter. Our Level-2 camera inspection documents the damage with photos you can see, and we provide a plain-English verdict: repairable, or needs replacement. Liner replacement in Union generally costs $2,500-$4,200 depending on flue height and appliance count. We also handle Chimney Repair in Union when the surrounding masonry requires attention.
Partial Chimney Rebuild
Union’s position in New Jersey’s freeze-thaw belt means winter temperatures repeatedly cross 32°F, causing cyclical expansion and contraction that spalls brick faces and opens mortar joints on mid-century chimneys. A partial rebuild addresses the damage - typically the top few courses, the crown, and sometimes one face of the chimney - without the cost of full reconstruction. We’ve rebuilt chimney tops on homes near Kean University where decades of water infiltration had reduced the crown to gravel. Partial rebuilds in Union run $3,500-$6,500, and we match existing brick where possible for a clean appearance from the street.

Common Chimney Liner & Rebuild Problems We See in Union Homes
- Oversized flues from fuel conversions. Most Union chimneys were originally sized for coal or oil and later converted to gas, leaving flue liners too large for proper draft. The result is acidic condensation that eats clay tiles from the inside out - a failure mode we diagnose regularly on inspections along Morris Avenue and Stuyvesant Avenue.
- Abandoned flues left open after direct-vent upgrades. Technicians working Union frequently find chimneys where the furnace was upgraded to direct-vent and the old flue connection was simply removed, never capped. Water, birds, and debris pour straight into the firebox. We cap these properly or reline for continued use.
- Freeze-thaw damage to brick and mortar. Union’s winter temperatures swing across the freezing point repeatedly, accelerating spalling and joint deterioration on the township’s aging brick chimneys. This water infiltration destroys liners from the outside in and often necessitates partial rebuilds sooner than in milder climates.
- Multi-appliance venting through single flues. Many Union colonials were built with one chimney serving furnace, water heater, and fireplace. When appliances are added or changed without proper relining, the flue becomes undersized or improperly configured - a common finding in our Level-2 inspections near Connecticut Farms.

Union’s pricing for liner and rebuild work is generally comparable to Cranford and slightly below some Essex County markets, but the specific cost depends on your chimney’s condition rather than your address. Union’s older housing stock - with its common fuel-conversion history and multi-appliance venting - often requires more extensive liner work than newer-construction suburbs, which can raise the total. Our free estimate gives you the exact number for your specific chimney.
Every liner installation and rebuild is covered by our 90-Day Done Right Promise in writing - if it’s not right, we make it right with no paperwork and no arguing. Manufacturer warranties on HeatShield, Gelco, and Olympia Chimney materials apply as well. We’ve been serving local communities since 1984, and we plan to be here when you need us again.
