Garden State Chimney Is a Trained & Qualified HeatShield® Resurfacing Provider

It’s a nice cool autumn evening. Right outside your window, bright vibrant colors swirl about in the breeze as the leaves fall from their branches. Sparked with sudden inspiration to enjoy a nice cozy fire, you approach the hearth and notice flecks of what appear to be hardened clay, almost like a small plant pot fell to its demise in your firebox. When you shine a light up into the flue, you find what must be your chimney liner, cracked and flaking off in pieces. No fire for you tonight.

While chimney liner damage is not always that obvious, operating a fireplace system with any level of liner inefficiencies is extremely dangerous. Fortunately, just because it’s damaged, doesn’t always mean that the only option is to tear out your chimney’s existing liner in order to replace it with something new.

Enter: HeatShield® repair systems – a restorative alternative for terracotta lined chimneys.

Here at Garden State Chimney, our chimney technicians are experts on all things chimney and fireplace. From HeatShield® installation to full masonry rebuilds, annual preventive services like chimney cleanings and level 1 and 2 inspections, our team is equipped to handle it all.

How Does HeatShield® Resurfacing Work?

Honestly, that is a great question. It’s crazy, right? The way in which a deteriorating clay liner can be revitalized and restored with the application of a specifically designed and uniquely derived material… The result of combining a high-fire ceramic with a high heat- resistant refractory cement…

There’s no doubt about it – HeatShield® is a powerful sealant that not only repairs existing liner damage, but reinforces the strength of the entire structure. What’s even more incredible is the range of damage that can be repaired thanks to HeatShield®, based on the way in which it’s applied. Bill Nye was right, science absolutely does rule.

In order to understand how this product works, we must first understand when and what it is used for. That’s where the level of sustained damage comes in and determines which of the three HeatShield® resurfacing methods would be most appropriate.

For Mild Damage In Mortar Joints…

Considering the reliability of clay chimney liners – they are, after all, still one of the most commonly used materials – it’s possible that only the mortar joints have suffered damages. Nearly impossible to tell without first having your annual chimney inspection or sweeping service, if you’ve been informed that your liner’s mortar is beginning to crack and crumble, the HeatShield® Joint Repair service might be just the perfect one for you.

When doing a Joint Repair service, we create a special applicator blade to the exact dimensions of your chimney’s flue, and utilizing a pulley-type system from the top of the chimney, ensure that each and every mortar joint is sealed by the HeatShield® “Cerfractory®” material. This service ensures that every gap between tiles is completely filled so flue gases and the harmful exhaust created during combustion can’t leak out of the liner and waft back into your living space.

For Cracked and Spalling Flue Tiles…

The next level up, so to speak, is the HeatShield® Resurfacing System. Designed for liners that might have sustained a bit more damage and, as a result, have cracks and spalling happening within the tiles themselves (as opposed to between them), this method requires the entire flue to be coated, not just the mortar joints. Application is relatively similar to that of the Joint Repair, but also a bit more intense, since we have to be sure the chimney is properly cleaned and prepared before applying the actual sealant.

For a Resurfacing service, we set up the specially-made applicator and use it to apply a material meant to remove any remaining dust and other particles from the walls of the flue, so that when we go in with the actual sealant, it adheres properly. After we’re done, we use a special camera to ensure everything is properly repaired and laying smoothly.

For Intense Damage or Unlined Chimneys…

The third and final HeatShield® repair method is used when a liner has suffered serious damage and trauma or in the case of an unlined chimney. This application is called the CeCure Sleeve Relining System and, like the name suggests, it is more of a relining than a repair. Utilizing a combination of HeatShield®’s patented “Cerfractory®” sealant and a thin sleeve of ceramic-insulated stainless steel, this system creates that extra support for a weakened chimney.

The most intense by far, this application process requires several steps and a whole lot of patience to ensure everything is done correctly. Essentially, this CeCure sleeve is sandwiched between two layers of the traditional HeatShield® sealant, which enforces the system much more holistically. And, of course, at the end, we’re sure to check it over using a camera, so we know that everything is properly sealed and ready to be safely operated.

This is a good time to note that just because you have a terracotta liner, doesn’t mean that your system inherently qualifies for a HeatShield® repair service. While they have the various methods to accommodate for a range in liner damage, some terracotta liners are too far gone for any restoration service and must instead be replaced by a liner alternative, like a stainless steel tube.

Are There Alternative Resurfacing Options To HeatShield®?

No, when it comes to having your chimney liner resurfaced, the only option out there is HeatShield®. However, there really isn’t any reason for there to be any resurfacing alternatives because HeatShield® products do such a great job. Look at it this way – if your chimney liner is eligible for a resurfacing service, HeatShield® is everything you need and then some.

It’s important to not confuse “resurfacing” with “relining,” though. If we’re talking about chimney relining options, then HeatShield® is not the only one. Clay liners might be one of the most common, but they are far from the only option when it comes to materials used to appropriately line a chimney. Metal is another commonly seen chimney liner because it is so easy to install and comes in many different kinds and alloys. Stainless steel is an excellent relining option, regardless of whether you have a prefab or traditional chimney system.

How Much Does It Cost to Resurface My Chimney With HeatShield®?

Do I Have To Have My HeatShield® Repair Inspected & Maintained?

Absolutely. Just because it is no longer damaged and vulnerable does not mean regular maintenance is no longer required. HeatShield® may be inimitable in its overall quality and flue protecting properties, but as with any other chimney system, annual chimney sweeping and inspection services are necessary to ensure that everything continues to function as it should.

Remember, we’re still talking about a chimney here. And where there’s a chimney, there is fire. No matter what is lining your flue or how frequently or infrequently you use your fireplace, in order to ensure that your system is as safe as possible, it’s important to stay up to date on your regular, preventive services. Plain and simple.
