Is Your Chimney Liner In Need Of Repair?

Every time you enjoy a fire in your fireplace or appliance, your chimney is working hard to contain the heat and byproducts of combustion, and to quickly remove these byproducts from the home. But over time, your chimney liner – be it clay tile or metal – can deteriorate or develop cracks and holes. When this happens, the heat of a fire can damage the brick and mortar of your chimney, accelerating the decay of your entire system. These cracks and gaps can also allow dangerous gases to escape the chimney system and seep back into your family’s air supply. In addition to shortening the lifespan of your chimney and polluting your air supply, a damaged chimney liner can allow the heat from a fire to ignite nearby combustibles, causing a house fire. If you haven’t had your chimney liner inspected recently, give us a call! Here at Northeastern Masonry & Chimney, we have the skills and materials to properly repair or reline your chimney, so that it can provide you with years of warmth and enjoyment.

Oil-Fired Appliances

The chimneys of oil-fired appliances are especially prone to decay, due to the acidic nature of oil combustion byproducts, like water vapor. In many cases, the liner walls will begin to spall or flake over time, greatly reducing the safety and efficiency of the entire system. In addition to the usual wear and tear that inevitably occurs in oil-burning chimneys, the newer high-efficiency appliances tend to require smaller flue sizes. Many homeowners are unaware of this and use their new appliance with the same flue liner they used with their previous unit. This can lead to all sorts of problems, allowing byproducts to remain in the chimney longer, where they can settle on the walls in the form of creosote or leak back into the home in the form of carbon monoxide. If your oil-fired appliance is in need of a new liner, we can install a quality stainless steel or cast-in-place liner that is designed for use with oil fuel. For more information, please refer to our Oil-Fired Appliances page!

Gas Appliances In A Masonry Chimney

Many people value gas appliances for their low maintenance and clean burn – but what many homeowners don’t know is that like other fuels, gas produces acidic byproducts and water vapor that can eat away at the masonry of your chimney if the liner is damaged or missing altogether. This not only destroys the chimney structure, it can also allow dangerous carbon monoxide back into your home and your air supply. Not all liner materials are approved for use with gas appliances, so make sure you have your system inspected and relined (if necessary) by one of the experts at Northeastern Masonry & Chimney.

Thermocrete Ceramic Sealant

If your chimney was built before 1922, it’s highly likely that your chimney lacks a flue liner altogether. Not only is this incredibly dangerous, it is also inefficient and incredibly destructive to your home and chimney system. At Northeastern Masonry & Chimney, we have extensive experience lining older, unlined chimneys using Thermocrete Ceramic Flue Sealant. This product was designed to seal and line masonry chimneys, without drastically altering the size of the flue. For more information on this process, please click here.

Smoke Chamber Sealant

The smoke chamber is the part of your chimney system that is shaped like an upside-down funnel and connects the firebox to the flue. It is this area of the system that ushers the smoke and other byproducts of combustion up into the flue and out of the home. Unfortunately, many times the smoke chamber doesn’t swiftly encourage smoke up and out, due to cracks, holes and other damage that often occur over time. If your smoke chamber has holes, cracks or is not parged smooth, it is important that you have it professionally-parged smooth and sealed. This will encourage smoke and gases out of the home, protecting your family from poor air quality and the inhalation of dangerous gases and fumes.
