  "summary": "Liner material, chimney height, and labor cost for a relined chimney flue.",
  "description": "Chimney liner replacement or installation is priced mainly by chimney height (which determines liner length needed) and liner material — stainless steel is the most common modern choice for wood or oil-burning appliances, while aluminum liners are cheaper but only rated for certain gas appliances. This calculator prices the job using a per-linear-foot material-and-labor rate for the chosen liner type, plus a flat cost for the top plate, cap, and insulation wrap that keeps flue gases at proper temperature to maintain draft and reduce creosote buildup. 2026 US national averages run about $2,500-$5,000 for a standard stainless steel liner installation in a typical two-story home's chimney (roughly 25-35 feet), with rigid stainless liners costing somewhat more than flexible ones but performing better in chimneys with offsets or bends. Aluminum liners, suitable only for certain gas appliances, run cheaper at $1,000-$2,500 installed. Always have a certified chimney sweep inspect the flue's condition first — a liner that's cracked, deteriorated, or wrong-sized for the connected appliance is both a fire and carbon monoxide safety hazard.",

  "faq": [
    {
      "q": "Why is stainless steel the standard choice for most liners?",
      "a": "Stainless steel liners handle the higher temperatures and corrosive byproducts of wood and oil combustion far better than aluminum, and most carry a lifetime warranty when properly installed — aluminum is only rated for the cooler flue temperatures of certain gas appliances and shouldn't be used for wood-burning fireplaces or stoves."
    },
    {
      "q": "Flexible or rigid stainless liner — which is better?",
      "a": "Rigid liners offer smoother interior walls for slightly better draft and are more durable, but flexible liners are easier to install around bends and offsets common in older chimneys — most residential jobs use flexible liners for exactly that installation flexibility, while rigid is preferred for straight, accessible flues."
    },
    {
      "q": "How do I know if my chimney needs a new liner?",
      "a": "A certified chimney sweep's inspection is the only reliable way to know — warning signs include visible cracks or gaps in an existing clay tile liner, excessive creosote buildup, a chimney fire in the flue's history, or an appliance being newly installed that's incompatible with the existing liner's size or material rating."
    },
    {
      "q": "Does chimney liner installation require a permit?",
      "a": "Requirements vary by jurisdiction, but many areas require a permit for chimney liner work, especially when it's tied to installing a new heating appliance — check with your local building department, and always use a certified installer (CSIA certification is a common credential) for safety-critical venting work."
