Expert Chimney Relining Services in Florida
Your chimney's flue liner is its most critical safety component. This inner lining contains combustion products, protects the chimney structure from heat and corrosion, and most importantly—keeps toxic gases like carbon monoxide from entering your living space. A damaged or missing liner puts your family at serious risk.
Chimney Repair Group has installed hundreds of chimney liners throughout Florida, from Miami stucco homes to Fort Lauderdale waterfront estates to Coral Gables Mediterranean-style villas. Our CSIA-certified technicians evaluate your specific situation and recommend the best liner system for your needs, budget, and appliance type.
When Does a Chimney Need Relining?
Several situations require new liner installation: cracked or deteriorated clay tile liners, unlined chimneys (common in homes built before 1940), changing from oil to gas heating, installing a wood stove insert, after a chimney fire, or when inspection reveals liner damage. Many homeowners discover liner problems during real estate inspections or insurance reviews.
Stainless Steel Liner Systems
Stainless steel liners are the most popular choice for relining, offering excellent durability, versatility, and value. We exclusively use 316Ti alloy stainless steel—the premium grade designed to resist corrosion from all fuel types including wood, gas, oil, and coal. Lesser 304 alloy liners (used by some competitors) corrode faster, especially with wood burning.
Stainless steel liners come in flexible (corrugated) or rigid configurations. Flexible liners work for chimneys with offsets, while rigid liners provide maximum draft efficiency. We assess your chimney geometry and recommend the appropriate type. All our stainless liner installations include a lifetime warranty when installed with our insulation systems.
Aluminum Liners for Gas Appliances
For gas-only applications (furnaces, water heaters, gas fireplaces), aluminum liners offer a cost-effective solution. These liners handle the lower temperatures and different combustion products of natural gas. However, if there's any chance you'll burn wood in the future, we recommend stainless steel for its versatility.
Cast-in-Place Liner Systems
Cast-in-place (or "poured-in-place") liners create a seamless, insulated flue by pumping a cement-like material around a form inside your chimney. This system is ideal for irregularly shaped flues, chimneys with significant offsets, or when preserving maximum flue size is important. Cast liners also reinforce weakened chimney structures. While more expensive upfront, cast-in-place liners can last 50+ years.
The Importance of Proper Sizing
A liner that's too large won't draft properly, causing smoke problems and increased creosote buildup. A liner that's too small restricts airflow and can overheat. Our technicians calculate the correct liner size based on your appliance BTU output, chimney height, and configuration. Proper sizing ensures safe, efficient operation.
Insulation: The Critical Addition
We strongly recommend insulating stainless steel liners in most applications. Insulation maintains higher flue gas temperatures, improving draft and reducing creosote formation. For wood-burning applications, insulation is essential. We use high-temperature vermiculite blankets that wrap around the liner before installation.
Code Compliance and Insurance
Florida building codes require properly lined chimneys for all fuel-burning appliances. Insurance companies can deny claims—or cancel policies—when chimney liner deficiencies are discovered. Our installations meet or exceed all applicable codes, and we provide documentation for your insurance records.

How long does chimney relining take?
Most stainless steel liner installations are completed in 4-6 hours—you can use your fireplace the same evening. Cast-in-place liners require 2-3 days for installation and curing. We work efficiently while maintaining our quality standards.
How long do chimney liners last?
316Ti stainless steel liners typically last 25-50 years with proper maintenance. Our lifetime warranty covers materials for as long as you own your home. Aluminum liners last 10-15 years. Cast-in-place liners can last 50+ years. Regular cleaning and inspection extends liner life significantly.
Can I use my fireplace immediately after relining?
With stainless steel or aluminum liners, yes—you can use your fireplace as soon as installation is complete. Cast-in-place liners require 24-72 hours of curing time before first use. Your technician will provide specific guidance.
Does my chimney need a liner?
Yes! Building codes require liners for all fuel-burning appliances. Unlined chimneys allow heat to transfer to combustible materials in your home, creating fire risk. They also permit carbon monoxide and other toxic gases to leak through mortar joints into living spaces. If your chimney is unlined, relining is urgent.
How much does chimney relining cost?
Liner costs depend on chimney height, liner type, and complexity. Typical ranges: aluminum liners $800-$1,500, stainless steel liners $1,500-$3,500, cast-in-place liners $3,000-$7,000. We provide detailed written estimates and explain all options so you can make an informed decision.
Can a damaged liner be repaired instead of replaced?
Sometimes. Minor cracks in clay tile liners can be sealed with specialized products. However, extensive damage, separated sections, or liners with multiple cracks typically require full relining. Attempting to repair severely damaged liners often wastes money and leaves hazards unaddressed.
What liner do I need for a wood stove insert?
Wood stove inserts require properly sized stainless steel liners with insulation. The liner must match your insert's outlet size—typically 6" for most stoves, though some require 8". We ensure your liner, insert, and chimney work together as an efficient, safe system.
Will relining improve my fireplace's draft?
Often, yes! Oversized flues (common in older homes) draft poorly because gases cool before reaching the top. A properly sized liner maintains gas temperature for better draft. Insulation further improves performance. Many customers notice dramatically better fireplace performance after relining.
Is the installation process messy?
We take extensive precautions to protect your home. Work is primarily done from the roof and at the firebox, with drop cloths and dust barriers in place. Our crews clean up thoroughly—you'll never know we were there except for your new, safe chimney liner.
Can I install a chimney liner myself?
While DIY kits exist, we strongly recommend professional installation. Improper sizing causes performance and safety problems. Incorrect installation can void warranties, violate codes, and create hazards. The cost difference between DIY and professional installation is minimal compared to the risks of getting it wrong.
