Flue Repair in New Jersey
Cracked tiles, corroded flue pipes, post-fire damage — we find it with a camera and fix it right. CSIA certified, same-day pricing.
Chimney Flue Repair in New Jersey
The flue is the interior passageway that carries smoke, heat, and combustion gases out of your home. When it's damaged — cracked tiles, corroded metal, gaps in the joints — those gases can leak into your living space. That includes carbon monoxide, which you can't see or smell.
We repair and restore chimney flues for homes across New Jersey. Whether the damage was caused by age, a chimney fire, thermal shock, or a heating system that was never properly matched to the flue, we find the problem and fix it. Every repair starts with a camera inspection so we know exactly what we're dealing with before any work begins.

How Flue Repair Works
You Call
Tell us what prompted the call — failed inspection, draft problems, smell from the fireplace, heating tech flagged an issue. We'll set up a visit.
Camera Goes In
We run a specialized camera down the entire length of the flue. Every crack, gap, and corroded section shows up on screen. You see it with us.
Diagnosis & Price
Based on what the camera shows, we recommend repair or relining and give you a price on the spot. Clear explanation, no jargon.
Repair or Reline
We fix what's broken. That could mean patching isolated damage, replacing a section of flue pipe, or installing a full new liner if the damage is widespread.
Post-Repair Camera Check
Camera goes back in to confirm the repair is right. You see the finished interior before we pack up. No surprises.
Cleared & Safe
Your flue is repaired, your chimney is safe to use, and you have the camera footage to prove it. We walk you through everything before we leave.
Flue Repair: What Homeowners Need to Know
Cracked Clay Tiles
Clay tile liners are what most older NJ homes have. They do a solid job when they're intact, but over decades of use, thermal shock takes a toll. Every time you light a fire, the interior of the flue heats up rapidly while the exterior stays cold. That temperature difference stresses the clay and eventually causes it to crack.
A cracked clay tile isn't just an imperfection — it's a breach in the barrier between combustion gases and your home's structure. Heat and carbon monoxide can escape through those cracks and reach the framing, insulation, and living spaces around the chimney. You can't see this damage from the firebox or from the ground. It only shows up on a camera inspection.
If the cracking is limited to a small section, a targeted repair can sometimes seal it. If the damage runs through multiple tiles or the tiles have shifted and separated, a new lining system is the safer path. We'll show you the camera footage and walk through the options honestly.
Corroded Metal Flue
Metal flue pipes — the kind that connect furnaces, water heaters, and boilers to the chimney — corrode over time. Moisture in the exhaust, acidic condensation from gas appliances, and simple age all eat away at the metal. A corroded flue pipe can develop holes or separations at the joints, letting exhaust gases leak into the basement, utility room, or walls.
This is especially common in homes that have converted from oil to gas heat without updating the flue. Gas appliances produce cooler, wetter exhaust that accelerates corrosion in pipes that were originally sized and built for oil. If your HVAC tech has mentioned the flue pipe during a service call, that's a sign it needs a closer look.
We inspect the full flue run — not just the visible connector pipe in the basement, but the entire path up through the chimney. Replacing corroded sections and reconnecting everything properly ensures your heating system vents safely. If the chimney's interior liner is also damaged, we can coordinate a full relining as part of the same project.
After a Chimney Fire
A chimney fire — even a small one that burns itself out — does serious damage to the flue interior. The intense heat can crack clay tiles, warp metal liners, and compromise the mortar joints between tiles. Even if the exterior of the chimney looks fine afterward, the interior may be severely damaged.
After any chimney fire, a Level 2 inspection with a camera is required before the chimney can be used again. This isn't optional — it's a safety issue and a code requirement. The camera will reveal the full extent of the damage: cracked tiles, displaced sections, heat damage to the mortar, and any structural compromises that aren't visible from the outside.
Depending on what we find, the repair could range from sealing a few cracks to a full relining of the flue. In severe cases, the chimney may need a full rebuild if the fire damaged the masonry structure itself. We'll give you a clear picture and a straight recommendation. For more on what to watch for, check our maintenance guide.
Flue vs. Liner
People use "flue" and "liner" interchangeably, but they're slightly different things. The flue is the overall interior passage of the chimney — the space where gases travel. The liner is the material that lines that passage — clay tile, metal, or a cast-in-place product. Think of the flue as the hallway and the liner as the walls of that hallway.
A flue repair might involve fixing the liner, replacing flue pipe connectors, sealing joints, or addressing damage to the chimney's interior structure. A full relining — installing a completely new lining system — is the more extensive version, usually needed when the existing liner has failed beyond what a patch can fix.
The distinction matters because the repair approach is different. A localized crack might need a sealant or a short section replaced. Widespread deterioration calls for a new liner. We use the camera to determine exactly which situation you're in, and we explain the difference in plain language — not trade jargon.
Draft & Performance Issues
If your fireplace smokes back into the room, if you smell something off when the furnace runs, or if the chimney doesn't seem to draw the way it used to — the flue is a likely culprit. Draft issues can come from a cracked or collapsed liner that's partially blocking the airflow, from a flue that's the wrong size for the appliance, or from buildup and obstructions inside the chimney.
A camera inspection shows us exactly what's going on. Sometimes it's a simple blockage — animal nests, fallen mortar, debris from a deteriorating liner. Other times, the flue itself has structural damage that's restricting airflow. And in some cases, the flue was never properly sized for the appliance it's venting, which means it's worked poorly since day one.
We fix the root cause, not just the symptom. If the flue needs to be cleared, we clear it. If it needs repair, we repair it. If it needs to be resized with a new liner, we handle that too. The goal is a chimney that drafts properly and vents safely — every time you use it. For seasonal maintenance tips that help prevent draft issues, see our blog.
When Relining Is the Answer
Not every flue problem can be fixed with a targeted repair. When the damage is extensive — multiple cracked tiles, widespread corrosion, a liner that's collapsed or shifted — patching individual spots doesn't solve the underlying problem. You'd be putting band-aids on a system that's fundamentally compromised.
In those cases, a full chimney relining is the right move. The old liner comes out (or gets bypassed) and a new system goes in — properly sized for your appliance, properly insulated, and backed by a lifetime warranty. It's a bigger job than a spot repair, but it solves the problem permanently.
We'll always try to repair first if it's the right call. But we won't recommend a repair that we know won't hold. If the camera shows damage that's beyond patching, we'll tell you — and we'll show you the footage so you can see it yourself. Honest assessment, clear options, pricing on the spot. That's been our approach since 2012, and it's why homeowners across NJ keep calling us back. Exterior repairs can be bundled into the same project if the masonry needs work too.
Flue Repair Questions Homeowners Ask
Most flue damage is invisible from inside the house. Warning signs include pieces of clay tile in the firebox, a strong smell from the fireplace when it's not in use, smoke coming back into the room, moisture or staining inside the chimney, or a failed annual inspection. The only way to confirm is a camera inspection — we run it down the full length of the flue and show you everything on screen.
A flue repair addresses specific, localized damage — a cracked tile, a corroded pipe section, a separated joint. A full relining replaces the entire interior lining of the chimney with a new lining system. Which one you need depends on how extensive the damage is. The camera inspection tells us that.
No — a cracked flue is a safety hazard. Carbon monoxide can leak through cracks in the liner and enter your home. Heat can reach combustible materials in the walls and framing. If you know or suspect your flue is cracked, stop using the fireplace and any connected heating appliances until it's been inspected and repaired.
Most targeted flue repairs — patching cracks, replacing a section of pipe, sealing joints — can be completed in a single visit. If the repair turns into a full relining, that's typically a one-day job as well, depending on the chimney. We'll give you a clear timeline when we provide the quote.
Yes — take that seriously. HVAC technicians see the flue connector and sometimes the base of the chimney during routine service. If they flagged something, it's worth getting a full camera inspection to see the whole picture. They're seeing one small section; we check the entire flue from top to bottom. Better to know now than to find out when something fails.
Almost certainly. Even a small chimney fire generates enough heat to crack tiles, warp metal, and damage mortar. A Level 2 camera inspection is required before the chimney can be used again after a fire. Based on what we find, the repair could range from sealing a few cracks to installing a full new liner or, in serious cases, a complete rebuild.
If the damage was caused by a covered event — a chimney fire, storm, lightning strike — your homeowner's policy may cover the repair. Damage from normal wear and tear is typically not covered. We recommend contacting your insurance provider before the inspection. We're happy to document the damage with camera footage and a detailed scope of work if you need it for a claim.
