What Is Chimney Relining and Why Does It Matter?
Your chimney liner is the inner lining of your chimney flue. It serves three critical purposes: it protects the walls of your home from the extreme heat produced by your fireplace or heating appliance, it channels combustion gases (including carbon monoxide) safely out of your home, and it protects the chimney masonry from the corrosive byproducts of combustion.
When a chimney liner is cracked, deteriorated, or missing entirely, your home is at risk. Heat can transfer through the chimney walls to nearby combustible materials, potentially causing a house fire. Dangerous gases can leak into your living spaces. And without a liner, the acidic flue gases will rapidly deteriorate the chimney masonry from the inside out.
Many older homes in Pittsburgh were built with clay tile liners, which can crack over time due to thermal shock and the freeze-thaw cycles that Pittsburgh is known for. Some very old homes, particularly those built before the 1940s in neighborhoods like Shadyside, Point Breeze, and the South Side, may not have liners at all. In either case, chimney relining is the solution.
Types of Chimney Liners We Install
Stainless Steel Liners
Stainless steel is the most popular and versatile chimney liner material. It works with all fuel types (wood, gas, oil) and all appliance types (fireplaces, furnaces, stoves, inserts). Stainless steel liners are durable, corrosion-resistant, and come with excellent warranties. We use only high-quality, UL-listed stainless steel liners.
Aluminum Liners
Aluminum liners are a cost-effective option specifically designed for gas appliances. They are lighter than stainless steel and work well for gas fireplaces and furnaces. However, they are not suitable for wood-burning applications.
Signs You Need a New Chimney Liner
Your chimney liner may need replacement if you notice any of the following:
- Pieces of clay tile falling into the firebox or found during a chimney inspection
- A chimney inspection reveals cracks, gaps, or deterioration in the existing liner
- Your home is older and has never had a liner installed
- You are converting from one fuel type to another (for example, from oil to gas)
- You are installing a new fireplace insert or woodstove
- You have experienced a chimney fire, which can damage clay tile liners
- Water is entering your chimney system
- You smell smoke or gas inside your home when the fireplace or furnace is running
Our Chimney Relining Process
When you call The Chimney Xperts for chimney relining, here is what to expect:
- Inspection: We start with a thorough chimney inspection to assess the condition of your existing liner and determine the right solution for your situation.
- Sizing: We measure your chimney and appliance to select the correct liner size. Proper sizing is critical for safe and efficient operation.
- Installation: We install the new liner from top to bottom, connecting it securely to your appliance and sealing the top with a proper rain cap and storm collar.
- Insulation: When required, we add insulation around the liner to improve draft, reduce condensation, and maintain proper flue temperatures.
- Final check: We verify everything is connected properly and functioning safely before we consider the job complete.
Why Pittsburgh Homes Need Proper Chimney Liners
Pittsburgh's older housing stock means that thousands of homes in the area have chimneys that predate modern building codes. Many of these chimneys have clay tile liners that have cracked or deteriorated over the decades, or no liners at all. Combine this with Pittsburgh's aggressive winter weather, and you have a recipe for chimney problems.
A properly installed stainless steel chimney liner is one of the best investments you can make in your home's safety and efficiency. It protects against fire, carbon monoxide exposure, and chimney deterioration for years to come.
