When does my chimney need a new liner?
When the existing clay tile liner is cracked, broken, or missing. When you're changing fuel type (e.g. converting to gas). When the flue is oversized for a new high-efficiency appliance. When an inspection finds spalled liner pieces on the smoke shelf. Or when insurance requires it after a chimney fire.
What's the difference between rigid and flex liners?
Rigid (smooth-wall) stainless liners offer better draft and easier cleaning — ideal for straight flues. Flex liners bend through offsets and curves where rigid won't fit. Both are UL-listed and equally safe; we recommend based on your chimney's actual geometry.
Do I need insulation around my liner?
In most cases, yes. Insulation keeps flue gases hot enough to vent properly, prevents corrosive condensation, and is required for many appliance manufacturers' warranty coverage. We always quote with and without insulation so you can see the value.
How long does a liner install take?
A standard single-flue stainless liner install with insulation takes 4–6 hours. Flex liners through complex offsets can take a full day. Multi-flue or large commercial liners may require two days. We always provide a written timeline before booking.
What's the warranty on your liner installs?
Every UL-listed stainless liner we install carries a manufacturer lifetime warranty against defect or failure. Our workmanship is also backed by a lifetime guarantee — if anything we install fails to perform, we make it right.
How much does a chimney liner install cost?
Standard residential stainless liner installs typically run $1,800–$4,500 depending on chimney height, flue diameter, insulation, and roof access. Flex liners and complex offsets cost more. Free written quote within 24 hours of inspection.
Will you handle the permits and inspection sign-off?
Yes. We pull all required permits, file the install paperwork with your municipality, and coordinate with the inspector for sign-off. You receive copies of everything for your records.
Can a chimney liner be installed in winter?
Yes — liners can be installed year-round. We work in any weather conditions Connecticut throws at us. Off-season installs (spring/summer) typically have shorter lead times and may be slightly cheaper.
