Delivering Peace of Mind: Installing a Stainless Steel Chimney Liner in Chester County, PA

Beautiful stone fireplace with a new flue installed.

There’s something timeless about a stone fireplace – the way it anchors a room with its rustic charm and provides warmth and ambiance through every season. The fireplace we worked on recently in Kennett Square, PA, was no exception. Nestled in a cozy room, this gorgeous stone masterpiece had been faithfully serving its home for decades, creating countless memories around crackling fires.

But like all well-loved fireplaces, years of use had taken a toll on the chimney system. To keep it safe and efficient for many more winters to come, we gave it the care it deserved. Our team relined the fireplace flue with a durable stainless steel liner system, insulated it with Thermix, installed a damper cap combo, and coated the smoke chamber with Chamber Safe for added protection.

Here’s how we did it – and why these upgrades are essential for any well-used fireplace.

What is a Fireplace Flue Liner and Why Does It Matter?

A fireplace flue liner is a crucial component of any chimney system. It guides smoke and dangerous gases safely out of your home while protecting the chimney walls from heat and corrosion. In older fireplaces, like the beautiful stone one we worked on, liners can deteriorate over time due to high temperatures, moisture, and creosote buildup.

 

This deterioration can put the safety of a home and loved ones at risk. These risks include chimney fires, carbon monoxide leaks, and structural damage. 

In this case, by relining the flue, we restored the safety and efficiency of this beloved stone fireplace, ensuring it can continue to provide warmth and ambiance for years to come.

The Benefits of A Stainless Steel Chimney Liner

For this project, we encouraged the property owners to install a stainless steel liner system. Stainless steel is one of the most durable and reliable materials for chimney relining. It offers:

  • Exceptional Durability: Resistant to rust, corrosion, and high temperatures, stainless steel liners can last a lifetime.
  • Versatility: Compatible with all types of fuel, including wood, gas, and oil, making it a great choice for any fireplace.
  • Enhanced Safety and Efficiency: A properly fitted stainless steel liner improves draft, reducing creosote buildup and preventing dangerous backdrafts.

In this home, the stainless steel liner not only provided a safer pathway for smoke and gases but also improved the fireplace’s heating efficiency. It was the perfect upgrade to preserve the charm and functionality of this stunning stone centerpiece.

Insulating with TherMix

After installing the stainless steel liner, the next crucial step was insulating it with TherMix. Insulation is often overlooked, but it plays a vital role in the safety and efficiency of a chimney system, especially in older stone fireplaces like this one.

TherMix is a Vermiculite-based masonry material. Once cured, it forms a lightweight, semi-hard barrier that insulates the chimney, keeping flue gases warm while maintaining safe temperatures on the exterior chimney surface. When poured into the chimney structure, TherMix fills any gaps and cracks, preventing airflow and moisture buildup between the new liner and the chimney walls.

Damper Cap Combo Installation

After insulating the liner, we installed a damper cap combo at the top of the chimney. This innovative device serves two essential purposes: it acts as a chimney cap and a damper all in one.

Why Install a Damper Cap Combo?

  • Energy Efficiency: Unlike traditional dampers located at the base of the chimney, a top-sealing damper prevents warm air from escaping when the fireplace isn’t in use. This helps lower heating costs and keeps cold drafts out.
  • Protection from the Elements: The cap shields the chimney from rain, snow, and debris, preventing moisture damage and blockages.
  • Pest Prevention: It also keeps out birds, squirrels, and other critters looking for a cozy nesting spot.
  • Convenience and Durability: Controlled with a simple pull chain inside the fireplace, this stainless steel damper cap is built to last and requires minimal maintenance.

The damper cap combo was the perfect addition to enhance energy efficiency and protect the newly relined chimney. It also complemented the rustic charm of the stone fireplace without compromising its appearance.

Finishing Touches: Applying a Coat of Chamber Safe

To complete the project, we applied Chamber Safe to the smoke chamber, a critical area that directs smoke from the firebox into the flue. Over time, smoke chambers can develop cracks and gaps, leading to poor draft and potential fire hazards.

Chamber Safe is a specialized fire-resistant coating that smooths out rough surfaces, filling any cracks or gaps in the smoke chamber. This improves airflow, ensuring smoke rises smoothly up the flue. By sealing vulnerable areas, it prevents heat from escaping to surrounding masonry, reducing the risk of chimney fires.

This fireplace relining project wasn’t just about fixing an old flue – it was about preserving the heart of a home. Now, with yearly cleanings, this chimney will be safe for years to come.
