Stainless-steel liners restore safety and draft when flue tiles crack, gaps open, or appliances change. We size and install liners for long-term performance in New England weather.

When to Reline
Tile-lined flues can fracture from thermal shock or settlement, creating gaps that allow heat and byproducts to escape into the chimney structure. Video inspection may also reveal missing mortar between tiles, offsets, or a flue that’s oversized or undersized for the connected appliance. A stainless-steel liner re-establishes a continuous, code-compliant vent path that improves draft, contains byproducts, and helps prevent carbon monoxide issues.
Liner Types & Sizing
We install stainless-steel liners in smooth-wall or corrugated configurations depending on height, offsets, and appliance needs. Proper sizing is essential: too large and draft suffers; too small and you risk smoke and overheating. We calculate liner dimensions based on venting charts, appliance output, and chimney height, then pair with insulation wraps or pours to stabilize temperatures and reduce condensation.
Installation Approach
After protecting work areas, we sweep the flue, verify dimensions, and prep the crown opening. The liner is lowered, connected to an appropriate top plate and cap, and secured to the appliance or connector below. We seal transitions, address thimbles, and test draft. You receive photos of key stages and a summary of materials and warranties.
Benefits
Relining restores a continuous vent path, improves draft for easier starts and steadier burns, and enables appliance updates without rebuilding the entire stack. In Danbury, CT’s climate, insulated stainless systems reduce condensation and creosote formation, extending the life of your chimney.

Ask About Liner SizingFAQ
How long do stainless liners last?
Quality stainless liners are designed for decades of service when properly installed and maintained.
Will a liner fix draft issues?
Often, especially when the existing flue is oversized or damaged. We also review smoke chamber and cap details for a complete solution.
Is insulation required?
Insulation improves performance, reduces condensation, and is often required by code or manufacturer specs—especially in exterior chimneys.
Do you provide documentation?
Yes—photos, materials list, and workmanship details for your records and future real estate needs.
