What To Expect From A Minneapolis Chimney Repair

By Lelia Hall


A chimney sweep is not enough to keep your smoke extraction system in good operating form. There are defects, which will arise as the structure is exposed to environmental elements such as snow, UV light, rainfall, and wind. If you are under the impression that what you need is a chimney sweep, then you might want to reevaluate your thinking. You cannot do without repairs of chimneys. A Minneapolis chimney repair contractor can help bring sanity in these structures.

Things like the mortar and bricks, capping, and crown will become defective with time. The capping structure is found on top of chimneys and is not part of the masonry work. It is the cover that you see at the top and it may be made of metal such as copper, steel, galvanized steel, or aluminum.

But the capping can be damaged due to action of weather elements. If damaged or missing, you should have it replaced or repaired. The capping structure helps prevent water from entering chimneys. When there is water penetrating inside chimneys, it brings many problems. The water causes the structures to deteriorate including the flues and bricks or mortar.

Well, there are things that can help you know if you need to have repairs on chimneys. You can check for the capping structure. The purpose of the cap is to keep away rainwater from entering chimneys. Capping may also help in preventing the entry of birds and other creatures like squirrels into the flues.

It causes rotting, growth of molds, freeze-thaw cycles, and moss growth- all of which wreak havoc to buildings and other structures. Therefore, if your building does not have the capping for chimneys, you should have them done or replaced. If the caps have damages, they can be repaired by a contractor. Another part of chimneys, which you need to check is the crown.

Any area where it feels soft needs to be repaired. Tuckpointing is only carried out to partially damaged mortar. If the mortar joints are left unchecked for a long time, they will fail completely and the bricks may become loose and exposed. Whenever this occurs, it means that you have to rebuild the structure and tuckpointing may not be applicable anymore.

If rainwater finds its way inside chimneys, it may cause the masonry work to deteriorate. The metallic flues may also corrode and develop weakness or holes that allow smoke and other gases to spread to a house. Capping can help in preventing the water from getting inside the chimneys.

Almost, all chimneys masonry will need tuckpointing in every 30 to 50 years. Because chimneys are half above the roofing structure and half below the roofing line, they may deteriorate at different rates. Usually, the structure above is exposed to harsher weather conditions such as wind, rainfall, snow, ice, and cold temperatures. It is likely to deteriorate fast. Such parts should be inspected and repaired if they are damaged.
