Chimney Liner Replacement in Hamilton, NJ
Hamilton Chimney Repair relines masonry chimneys in Hamilton and the surrounding Mercer County towns: cracked clay tile, flues sized wrong for a new appliance, and liners that failed a Level 2 inspection. The work is done from the top down, in one visit where the flue allows it.
A liner is the part of the chimney that keeps combustion gases inside the chimney. When the clay tile cracks or the joints open up, heat and carbon monoxide reach the brick, the framing, and eventually the house. It is not a repair to defer over a winter.
When a chimney needs a new liner
Cracked or shifted clay flue tile
Clay tile fails at the joints first, usually after a chimney fire or years of condensing flue gases. Once the joints open, the liner is no longer a liner. A camera scan settles it in ten minutes.
A flue sized wrong for a new appliance
High-efficiency furnaces and water heaters put out cooler, wetter exhaust than the chimney was built for. An oversized masonry flue condenses that moisture and eats itself from the inside.
A liner called out on inspection
If a Level 2 report lists the liner as compromised, the appliance should not be run until it is relined. We work from the report and re-scope the flue after installation.
How we reline a chimney in Hamilton
- Camera-scope the full flue and measure the appliance outlet and connector run.
- Size the liner to the appliance, not to stock, and confirm whether insulation is required.
- Break the crown or remove the cap for access, then drop and set the liner from the top.
- Connect at the appliance with a listed tee or appliance connector, and support at the top plate.
- Rebuild or re-seal the crown, fit a stainless cap, and re-scope the finished flue for the file.
Materials and sizing
316Ti stainless for gas and oil appliances, 316L or heavy-wall 304 for wood, sized to the appliance outlet and the connector run, not to whatever is on the truck. Insulation wrap or vermiculite mix where the flue is oversized or runs up an exterior wall. Clay tile relining stays on the table when the chimney is sound and the homeowner wants like-for-like.
What liner replacement costs in Hamilton
Price follows flue height, diameter, whether the chimney has offsets, whether insulation is required, and how the roof is accessed. A three-storey slate roof needs staging that a ranch does not. We look at it, then send a written line-item price that names the liner being installed and its listing. No deposit before you have seen that.
