HeatShield Is a Great Option for Relining Your Chimney

Do you live in an older home with a masonry chimney? If so, it probably has a clay tile flue liner. Clay tiles have been used to line chimney flues since the beginning of the 20th century, and there are excellent reasons why. These tiles can withstand extremely high temperatures, and they hold up well against the corrosive byproducts of combustion that pass through the flue on their way out of the chimney. Once installed, clay liners will stay in good shape up to 50 years. However, when the clay tiles become cracked and chipped over time, it can be costly to repair them or to replace the liner as it is a very difficult and time-consuming task. When the HeatShield Chimney Repair and Resurfacing System was developed around 20 years ago in Europe, repairing and relining a clay tile liner became so much easier and less costly. At Weststar Chimney Sweeps, our technicians are experienced with using HeatShield, and our customers who have had their clay flue liners repaired or replaced with this product have all been very satisfied. We would like to tell you more about HeatShield and what it can do for your clay tile-lined chimney.

HeatShield Chimney Relining - San Diego CA

What exactly is HeatShield?

Made from a specially formulated “Cerfractory” sealant material, HeatShield can restore the integrity of your chimney’s flue to vent out toxic gases from your home. Eliminating the dangers in your flue caused by cracks, gaps, and spalling, HeatShield will make your chimney as safe and as efficient as it originally was when first built. Depending on the condition of your clay tile liner, the Joint Repair system or the Resurfacing System will be used.

What does the Joint Repair system do?

If our chimney inspectors at Weststar Chimney Sweeps only find mortar joints in your clay tile liner that are deficient, we will use the Joint Repair system. First we will make a custom-made foam applicator blade to fit your chimney. Once this tool has been inserted into your chimney and positioned below each gap or void, we will then add the HeatShield Cerfractory Flue Sealant mixture. Each void and gap will be filled, and when we pull out the foam applicator blade, it will smooth the filled gaps and voids as it comes out of your chimney. Then we scan the repair with a special video camera to be sure the repairs have been done correctly.

What does the Resurfacing System do?

If your chimney liner has a flue that is spalled, but is also structurally still sound, we will use the Resurfacing System. We will pull a custom-fit foam applicator from the bottom of the flue up through top by way of a wench attached to the top of the chimney. We then prime and clean your old liner with a “tie coat” material, which is applied to the flue walls by pulling the plug upwards with the winch. After this coat dries, we then apply the HeatShield mixture with the foam plug in the same way we applied the primer. This method is called “slip casting” or “slip cast extrusion.” After this is applied, we will look at the scanned video to be sure your entire chimney is sealed and smoke-tight.

Your Spring Cleaning Should Include Your Chimney

Schedule a chimney sweeping and inspection as part of your spring cleaning!

Schedule a chimney sweeping and inspection as part of your spring cleaning!

March is upon us, which means spring is finally here. For homeowners, the arrival of spring means it is time to get started on annual spring cleaning chores. If you have a fireplace or wood stove in your house, that means your chimney should also be included. Weststar Chimney Sweeps is ready to help you with your chimney cleaning chores, and we would like to tell you more about our chimney sweeping process.

Why should I have my chimney cleaned and inspected in the spring?

It makes sense to have your annual sweeping done in the spring because most people schedule their annual chimney inspections in the fall, so you will not have a problem getting the appointment you want. Also, the sooner you have your chimney looked at after the heating season, the better. If there are problems that need repairing, you need to get them repaired quickly so no more costly structural damage occurs. The Chimney Safety Institute of America (CSIA) recommends homeowners have their chimneys inspected annually, so why not get into the habit of scheduling this appointment in the spring?

What should I expect from a chimney sweeping and inspection from Weststar Chimney Sweeps?

When you schedule a chimney sweeping and inspection with Weststar Chimney Sweeps, one of our licensed and certified technicians will come to your home and begin the inspection and cleaning process. Using modern technology, we use video cameras to allow us to closely examine the interior of your chimney and decide which type of cleaning technique we will need to do, based on the type of creosote build-up in your chimney and what kind of chimney you have. We use a few different chimney sweeping techniques, which include:

Standard Sweeping

Using the typical rotating brushes on long handles, along with a high-powered vacuum with a HEPA filter to keep debris and soot from getting in your home, this technique is effective for getting rid of average creosote deposits; however, if you have any major creosote build-up, as in 3rd stage, you will need a heavier-duty sweeping.

Mechanical Cleaning

In order to remove hard or glazed creosote deposits, high-speed rotating wire brushes, plastic cables, or specials chains are used to do the sweeping.

Chemical Cleaning

Sometimes mechanical cleaning is not enough, and chemicals may have to be used along with the high-speed rotating power tools to get rid of big deposits of glazed creosote.

What happens after the chimney inspection and sweeping is completed?

Once we do your sweeping and inspection, we will assess our findings and determine whether or not you need any repairs done to your chimney. Other than creosote build-up, the most common damage to chimneys seen after winter is water damage from leaks. If left unrepaired, this can lead to further, more costly structural damage. Weststar Chimney Sweeps can handle all of your chimney repair needs, if repair is necessary.

Do not forget your chimney when you are spring cleaning. Contact Weststar Chimney Sweeps to make an appointment for your annual chimney sweep and inspection.
