Most homeowners underestimate liner costs because they focus only on material pricing. The full project scope includes labor, roof access, insulation, and potential masonry corrections. In 2026, stainless steel liner installations in Brooklyn may range from $2,500 to $7,500. Heavily deteriorated chimneys requiring tile removal or structural relining with cast-in-place systems can exceed $10,000. Aluminum liners for basic gas appliances may start lower, often between $1,800 and $3,500, depending on height. Primary cost factors include:
- Site complexity such as roof pitch, height, and scaffold requirements
- Material costs including stainless steel grade and insulation type
- Total scope, such as crown repair, damper replacement, or flue tile removal
One homeowner attempted to install a budget liner purchased online without insulation. Draft problems caused persistent smoke backflow, and the liner had to be removed and replaced. The second installation cost more because creosote buildup required additional cleaning. Most standard liner projects take one full day, while complex restorations may extend to two or three days. These figures are preliminary benchmarks for informational purposes only and do not constitute a binding quote. An on-site evaluation is required for a final proposal.
