Cast-in-Place
Chimney Liners
Did you know? Cast-in-Place is the only lining system tested and approved for safety after multiple chimney fires? Chimney Savers is the only company in Vermont and New Hampshire that gives you the option of a “cast-in-place” – also known as a “poured-in-place” – chimney lining system.
Cast in Place Chimney Liners stand out as the premium choice for homeowners seeking durability, safety, and ease of maintenance. They are installed by pumping a concrete-like material around a former, which is inserted down the full length of the chimney. After the lining sets, the former is removed, giving you a smooth, seamless, and extremely well-insulated chimney liner.
Benefits of Cast in
Place Chimney Liners
Cast‑in‑place liners do more than cover a problem—they strengthen your chimney from the inside out. They bond to existing masonry, handle extreme heat, and insulate the flue to help cut creosote and moisture. They’re approved even after multiple chimney fires, safe at zero clearance to combustibles, and made from durable, eco‑friendly materials that resist acidic corrosion.
Below are the key benefits and what they mean for your home.
Safety and Durability
One of the main reasons homeowners choose cast-in-place liners is their remarkable resistance to high heat and chimney fires (up to 2100°F). Our liners are the only type approved for use after multiple chimney fires, ensuring long-lasting safety for your home.
Structural Integrity
These liners bond with the existing masonry, sealing cracks and gaps, thus significantly enhancing the structural integrity of your chimney. They are particularly valuable for older, deteriorated chimneys that need reinforcement.
Temperature Resistance
With superior insulation properties, cast-in-place liners maintain higher flue gas temperatures, reducing the potential for creosote buildup and water condensation—common causes of chimney issues.
Zero Clearance to Combustibles
Our cast-in-place liners allow for zero clearance to combustible materials, meaning wood or insulation can be positioned right against the chimney without risk, providing added flexibility in home construction and renovation.
Environmental Benefits
Made from natural, environmentally friendly materials, our chimney liners do not emit harmful substances and resist corrosion from acids found in gas and oil applications.

I hired Chimney Savers to install a wood stove insert and a stainless steel liner for the chimney - not trivial. These guys did a great job. Responsive, good price and they showed up on time, got the job done early. I would totally recommend them.

How Cast in Place
Chimney Liners Are Installed
The installation process begins with the removal of existing clay tiles and any deteriorated masonry. We then install a temporary chimney former that defines the flue's shape and size. As we pump the cast-in-place material around this former, it fills all voids, cracks, and gaps, creating a solid, insulated lining. After a curing period, the former is removed, leaving behind a durable, seamless liner.
Proper installation is crucial to achieving the long-term benefits of your cast-in-place chimney liner. That’s why we emphasize the importance of having skilled technicians perform this service.
