Chimney Liner Installation & Replacement in New Jersey
AM Chimney Sweep installs and repairs chimney liners for homeowners throughout New Jersey. A damaged liner can let heat, smoke and creosote reach the surrounding masonry. We inspect, repair or replace liners so your chimney vents safely.
Why chimney liners matter
- Protect the surrounding masonry from heat and combustion byproducts
- Help keep smoke and carbon monoxide from entering your home
- Stop water and moisture damage from a cracked or deteriorated liner
- Keep the chimney venting safely and meeting current code requirements
- Reduce fire risk from an unlined or deteriorated flue
- Extend the life of your chimney system
Fire safety: A cracked, corroded or missing liner lets heat and combustion gases reach nearby wood framing, increasing fire risk. Most liner damage is not visible without an inspection. Tip: If you notice white staining on the outside masonry, cracked or missing flue tiles or a smoky smell, your liner may need repair or replacement.
Our chimney liner process
- Inspect the existing liner and flue with a camera
- Measure the flue and appliance to size the new liner
- Remove the damaged or outdated liner
- Install the new liner, sized for your heating appliance
- Seal and insulate the liner as needed
- Reinstall the chimney cap and verify proper draft
- Final safety check and report
Tip: A properly sized liner keeps your chimney venting safely and helps it meet current code. See a finished liner job in Jersey City and more in Our Work.
Signs you need a new chimney liner
- White or gray staining on the outside masonry (efflorescence)
- Rusted, cracked or missing flue tiles
- Chunks of tile debris in the fireplace or firebox
- Smoke smell or backdrafting when the fireplace is in use
- Visible gaps, cracks or crumbling inside the flue
- A prior chimney fire, or scorch marks near the flue
Safety note: A deteriorated liner can let carbon monoxide and heat escape where they should not. If you suspect liner damage, stop using the fireplace and schedule an inspection.
