Chimney repair is an intricate task. Repairing and maintaining chimneys involves more than just scraping and brushing off the old mortar and stucco that line the flue. There are many things that damage masonry materials in chimneys. A small crack or fracture can allow cold air and particles from outdoors to enter and freeze in the flue making it difficult to heat the house. This can cause significant damage to the roof, attic and foundation if not repaired quickly.
Carbon monoxide, otherwise known as carbon monoxide, is the result of fuel burning in a fireplace. If this happens to the chimney, your home’s occupants could experience symptoms such as disorientation, headaches, nausea, upset stomach and confusion. The high level of carbon monoxide in the flue can also be deadly. Chimney fires are a leading cause of accidental deaths in North America. To ensure that you protect your family and reduce risks of accidental fires, chimney repair and maintenance is a critical step towards safe chimney operation.
Two types of chimney repairs exist: exterior chimney repairs and interior chimney repairs. Exterior chimney repairs include fixing damage to the exterior of your home. These repairs may include repairing cracks or holes. They also may include putting down a chimney cap to seal against rain, snow, hail and ice, as well as sealing loose seams on the exterior and inside the flue. In some cases, the chimney repair may require that the mortar be removed entirely, although this is not generally done.
Interior chimney repairs include fixing a problem with creosote buildup inside the chimney. Creosote buildup can occur due to age, weathering and/or misuse of the flue. Some chimney fires may result in creosote buildup around the firebox. If this creosote buildup is allowed to build up and harden, it will cause your chimney fires to be more damaging to your home. You may need to get a chimney cap to cover the fireplace so that the creosote does not gather and harden inside. A chimney repair will often involve some type of penetration or excavation.
In some cases, a chimney repair may also involve removing masonry bricks from around the outside of the flue. This masonry bricks are made out of cement and are part of the brick lining the inside of the chimney. These bricks are known as creosote premix and if they become wet, they can be very difficult to remove. If the bricks are removed and the creosote buildup is allowed to harden, you can end up with a brick wall inside the fireplace. This wall can be very dangerous because it can catch fire easily.
Chimney repairs can be performed by licensed contractors who are experienced at repairing masonry chimneys. The cost of such repairs can be significantly reduced if you have a contractor that can perform the repairs at a reasonable price. It is important to discuss your needs with the contractor before you begin any work. There are many different types of repairs that can be made and it is important that you understand what type of repairs will be needed in your case.
