Relining installs a new, correctly sized liner inside your chimney so heat and gases vent safely instead of leaking into your walls. It is the fix when a clay-tile liner has cracked, when you change appliances, or when a chimney was built with no liner at all.

When you need a chimney relined

• A camera inspection shows cracked or spalled clay tiles
• You had a chimney fire, which commonly cracks the liner
• You are switching fuels or installing a new stove or insert that needs a different flue size
• The chimney has no liner (common in older Fox Valley homes)
• Heavy creosote glazing or corrosion has damaged the existing liner

Why a good liner matters

The liner is what keeps flue gases and intense heat inside the chimney and out of the wood framing around it. A cracked or missing liner lets heat reach combustibles and lets carbon monoxide seep into living space. It also protects the masonry from acidic condensation that eats brick and mortar from the inside.

The liners we install

We install stainless-steel liners — flexible for offset chimneys, rigid for straight runs — and add insulation where the code and appliance call for it. Stainless is rated for wood, gas, and oil, and a quality liner is built to last decades. For gas conversions we install the correct aluminum or stainless liner for that appliance.

What relining costs

Cost depends on the liner type, length, and whether insulation is needed, so we quote after an inspection as a flat up-front price. See our pricing page for starting ranges.
