What You Need to Know About Chimney Resurfacing with FireGuard

Chimney relining and resurfacing is an important service that not only helps preserve the structural integrity of your chimney, but also reduces the risks associated with carbon monoxide leaks and potential house fires.

As your chimney liner naturally deteriorates over time due to the continuous use of your fireplace, it can create hazardous situations, like carbon monoxide leaking into your home or opportunities for flammable creosote to accumulate – should it ignite, you could find yourself with a dangerous chimney fire.

What Is Chimney Relining and Resurfacing?

The bad news about chimney liner damage is that it is not easy to spot with the naked eye. Most of the time, people are only made aware of chimney liner damage after it has already led to potentially hazardous situations or costly repairs. This is why organizations like the Chimney Safety Institute of America (CSIA) recommend annual chimney inspections and sweeps completed by a professional technician who knows what to look for.

So, what’s the difference between relining and resurfacing?

Simply put, chimney relining is the process of adding a new liner or replacing an existing one within the flue of the chimney. Chimney resurfacing, on the other hand, involves restoring or reinforcing the interior of the chimney’s flue with a ceramic material.

Why Are Chimney Liners Important?

The chimney liner is an important component of a chimney system because it provides a protective barrier between the inside of the chimney and the surrounding structure of your home.

In fact, the National Fire Protection Agency (NFPA) 211 states, “If the flue liner in a chimney has softened, cracked or otherwise deteriorated so that it no longer has the continued ability to contain the products of combustion (i.e., heat, moisture, creosote, and flue gases), it shall be either removed and replaced, repaired, or relined.”

That’s because chimney liners serve multiple purposes including:

  • Improved Safety: Lining the flue with a strong and durable barrier reduces your risk of fire hazards. As previously mentioned, it also protects the health and well-being of your household by preventing carbon monoxide and other dangerous gases from leaking into your home.
  • Enhanced Efficiency: By helping increase the draft and airflow within your chimney, this in turn allows for more efficient combustion – meaning you’ll enjoy better heat output from your fireplace, while using less fuel.
  • Extend Chimney Lifespan: Relining not only reinforces the chimney structure, but helps prevent moisture intrusion that would only cause even more significant damage over time. When a chimney can better withstand the stress of regular use and exposure to weather, you are able to extend the lifespan of your chimney all together.
  • Cost Effective: By addressing the issues of cracks and deterioration early on, you can avoid costly repairs or even rebuilds later on down the line. Trust us – without a proper liner in place, your chimney is eventually going to face some serious damage.

Why Choose FireGuard?

When it comes to chimney relining and resurfacing, there are a few different options to consider based on the extent of the damage, the type of liner, and your specific needs and budget.

One of the most popular methods we offer is FireGuard. It is a patented system designed to correct mortar joints, misaligned flue liner sections, and fractures and cracks within flue liners. The system uses a military grade vibrator installed within the applicator to penetrate mortar joints and fractures, as well as to help distribute a consistent ceramic coat for resurfacing.

The best parts?

  • It can be installed in any size or shape flue liner.
  • It can repair open joints in the flue.
  • It has a temperature rating of 3,205 F, which is the highest rating in the industry.
  • The process typically costs less than relining.
  • The process does not appreciably decrease the area of the original flue, so the performance of the fireplace or appliance will not change.
  • The process is quick and usually completed in less than a day.
  • There are fewer disturbances to the inside of the home since the flue liners are not removed.
  • It’s been around since 2003.
  • A limited, lifetime factory guarantee against material failure is provided with every FireGuard mortar joint repair.
  • A 20-year limited factory guarantee against material failure is provided with every FireGuard resurfacing repair.

It’s only been in the last few decades that this type of restoration to a ceramic flue was available. Before, all you could do was demolish the current flue structure and replace it with a stainless steel flue. This is considered relining the flue. This may still be the only option if the liner has so much damage it cannot be restored. However, if at all possible, we use the FireGuard System.
