If it's broken, we can fix it.
THE FLUE LINER
One of the most common and most important findings during an inspection is a damaged, deteriorating or missing flue liner. For decades, chimneys were constructed without flue liners, which is now known to be incredibly dangerous. Flue liners are designed to restand the temperatures of a fire and contain the byproducts of combustibles, protecting the masonry and walls of your home. In addition to offering protection and reducing fire risks, the chimney flue is also responsible for removing smoke, carbon monoxide and other byproducts from the home without allowing any of it to leak back into your air supply.
For many years, flue liners were solely made from clay tiles. Nowadays, we also frequently install aluminum or stainless steel liners. The type of flue liner you need will depend upon your fuel type.
MY FLUE IS CRACKED, WHAT NOW?
If your flue liner is damaged, we will be able to clearly see what is going on after a video scan is performed. The good news is no matter what we see, you have options. Depending on the level of decay, we may be able to simply resurface your existing clay liner with CeCure’s HeatShield® product. The process is relatively quick and can restore your liner to safe use once more.
TELL ME MORE ABOUT THIS HEATSHIELD®
HeatShield® is a cerfractory sealant made by CeCure Chimney Systems that is designed to restore or reline clay flues. There are a few ways in which HeatShield® can be used, and each method is chosen based upon the level of flue degradation:
1. Joint Repair Method – The joints of your clay liner can undergo some pretty serious damage from moisture and heat. When this happens, the safety of the chimney system is compromised and repairs need to be made. To repair these joints, we can apply the HeatShield® product, smoothing it over with a foam applicator. The result? A flue that’s safe for use!
2. Flue Resurfacing – Sometimes, a clay flue liner needs more than just a few patches here and there. If your flue is extensively damaged, but your chimney itself is still in reputable condition, we may simply opt to resurface your flue liner with HeatShield®. We start out by creating a custom foam applicator, applying a prep coat to your entire flue, and then pouring the HeatShield® product down into the flue once the prep coat dries. Next, we use the foam applicator to ensure that the product is smooth and has filled every gap and crack. What are you left with? A smoke-tight flue, without the cost of a rebuild!
3. CeCure Sleeve Relining Method – If your masonry chimney is unlined, we can use that very same HeatShield® product to fully line your system! We start out with a custom foam applicator and a prep coat, just as we do when resurfacing a flue liner. Next, we apply a layer of HeatShield®, slip a “sleeve” down into the chimney flue, and then apply another layer of HeatShield®. What you end up with is a durable new flue liner that is able to withstand even the most extreme temperatures.
WHAT IF MY FLUE LINER IS MISSING?
If your liner is missing or beyond repair, we will most likely opt to install a new stainless steel or aluminum flue liner. Although aluminum is less expensive than stainless steel, stainless steel liners are safe for use with all fuel types (which is good to know, if you’re considering a switch in the future), and they are also corrosion-resistant and often come with a lifetime warranty.
