How To Fix a Cracked Chimney Flue?
A flue is present in any home that has a chimney. For the protection of your health and safety, you should at most have a flue. Chimney flues shield your home from potential heat transfer-related combustion, guard your masonry from creosote, a fire’s waste, and boost the overall efficiency of your fireplace.
These days, cast-in-place or metal chimney liners and flues are popular. They provide an incredible amount of protection and are built to last a long time. They won’t, however, endure indefinitely. Stress and frequent usage may eventually wear down your flue and may require repairs. That’s our role here!
In this blog, we will cover, what is chimney flues, how they crack, how to fix it and how professionals can help you with this. Let’s delve inside together:
How does the chimney flue crack?
Due to their low installation costs, clay flue liners are found in a large number of chimneys across the nation. They are not as durable as cast-in-place or metal liners, though.
The uneven distribution of heat through the chimney is the most common cause of broken clay tiles. The tiles buckle and break due to uneven absorption of heat because clay cannot take in heat as well as other substances do.
These clay liner cracks have the ability to eventually cause hazardous conditions, like dangerous gas leaks into the house or an increased likelihood of chimney fires. For this reason, to detect broken liners early on and avoid expensive repairs or possible risks, routine inspections and suitable maintenance are essential.
Does my chimney flue need to be lined?
Your property may already have a lined chimney if it was constructed after 1965. Flue liners aren’t required by Building Regulations, but if you plan to install a wood-burning stove, for example, your current chimney must pass a test for smoke to verify that it is solid in structure. In this scenario, the most likely reaction is that you must line your chimney flue. It also needs to pass Building Regulations, have the right diameter to fit your stove, and fulfil the specifications set out by the stove manufacturer.
What Can Go Wrong with My Flue?
Your chimney flue may have a number of problems, especially if it isn’t serviced on a regular basis. Hazardous gases like carbon monoxide may get into your home through fractures or damage to the flue liner, which is frequently brought on by ageing or heat stress. This increases the possibility of chimney fires and poses significant health dangers.
Another frequent problem is blockages, which usually come on by garbage, bird nests, or creosote buildup. These obstacles may prevent adequate ventilation, which could result in low-quality air or the back drafting of hazardous gases and smoke into residential neighbourhoods.
Finally, an inefficiently installed flue liner or deteriorating flue liner may reduce heat loss unevenly. Higher energy bills and possible harm to the chimney’s structural integrity could arise from this. Frequent cleaning and inspections may help in avoiding any of these issues.
How to Fix a Cracked Chimney Flue?
If you find damage or cracks in your chimney flue, you must fix it right away to avoid more issues. The nature and scope of the damage will influence the repair strategy. These are the most commonly used techniques for fixing a broken chimney flue:
- Replacement of Clay Tiles: If the damage is minor, you can replace individual tiles if the chimney has a clay liner. In this process, the broken tile is taken out and a new one is fitted. But if the cracks are extensive, an additional repair might be required.
- Relining the Chimney: This is usually the best course of action for greater damage. To build a fresh, seamless flue, a cast-in-place or stainless steel liner can be set up. Metal liners are more durable and remain intact in the presence of high temperatures.
- Cast-in-Place Liner: With this method, a substance that resembles cement is poured straight into the chimney and hardens to form an insulated flue that is sturdy. This strengthens the chimney’s structural integrity alongside fixing any existing damage.
- Flue Sealant: A heat-resistant sealant can be utilized to fill in the gaps that result from small cracks. This is a temporary measure that can delay a more comprehensive repair while preventing additional harm.
How Professionals Can Help?
Chimney flue repair is not a do-it-yourself activity, it is not an activity that does not require any skills. In order to make sure that everything gets done safely and correctly, particular tools, expertise, and knowledge are needed. Professionals in chimney service areas can assess the severity of the damage or the risk associated with it and propose the best course of action, which may include flue sealing, relining the chimney, or replacing individual tiles.
You may be sure your chimney is secure and functioning properly by hiring a professional chimney technician. Professionals can provide you with peace of mind and avoid potential problems by doing smoke tests, cleaning up creosote buildup, and checking your chimney for any concerns.
