When Is a New Chimney Liner Needed?
Chimney liners fail for several reasons: age, chimney fires, moisture intrusion, acidic exhaust from modern heating appliances, and simple mismatch between the flue and the appliance it serves. Clay tile liners can crack and separate at the joints; metal liners can corrode; unlined chimneys simply aren’t safe. If you’re converting fuel types, replacing a furnace or boiler, or you see signs of damage during an inspection, relining is often the correct fix.
Our Stamford team assesses the full venting system—appliance input, connector size, chimney height, offsets, and existing flue condition—to design a liner that drafts properly, resists condensation, and meets modern standards. The result is safer operation and better performance from your fireplace or heating system.
Why Stainless Steel?
Stainless steel liners deliver outstanding durability and adaptability. They can be insulated to improve draft and reduce creosote, shaped for chimneys with offsets, and precisely sized for the appliance they serve. In coastal Connecticut, stainless resists the corrosion that salt-laden air and condensation can accelerate. With proper installation and a quality cap and crown, a stainless liner is a long-term solution for both masonry and manufactured chimneys.
We install both flex and rigid stainless systems. Flex is ideal for navigating offsets or irregular flues; rigid sections provide ultra-smooth interiors for excellent draft on straighter stacks. We’ll recommend the right approach after a camera scan and measurement.
