Chimney liner installation in Mansfield typically costs between $2,500 and $5,000, depending on the type of liner and complexity of your chimney system. Stainless steel liners, which we recommend for most applications, usually range from $900 to $3,800 for materials and installation. The final cost depends on your chimney height, diameter, and whether we need to remove an old liner first. Furnace and boiler liner installations are often less expensive than fireplace liners because they require smaller diameters and fewer components. We provide detailed estimates after inspecting your specific chimney system. This ensures you get accurate pricing based on your actual needs, not generic estimates that might not apply to your situation.
