When You Do Need To Services Of Minneapolis Chimney Repair Contractors

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.

Moisture is probably the number one form of destructive forces that you have watch out for in chimneys. Damaged caps will allow water to enter in flues and cause a lot of damage. While the interior part may be exposed to extreme heat more than the upper part, it is most shielded from the harsh weather and the rate of deteriorating may be slow.

The part that is below the roof remains much protected. It is important to check the mortar joints on the section above the roofing. You can check for separations, cracks, and spalling. Separations between brick and mortar may occur due to the weather elements. You can use a screwdriver to try to scrape the mortar or the bricks to see if they are soft and beginning to flake away.

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.

A majority of the repairs in chimneys consist of caps. When the caps are damaged, they will allow moisture to enter in chimneys. This is among the destructive forces in chimneys after the heat. Heat from the fireplaces as well as the moisture and water from rainfall will take a tall on chimneys. If these elements are not checked properly, it could spell disasters to the chimneys.

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.

The salts are brought to surface and when the water evaporates, the white marks are left out. While you may do away with the stains using warm soapy water, it may not solve the moisture problem. You will need to identify what is causing the moisture and then have the right remedy provided. In most cases, a chimney cap or a missing crown may be the cause of moisture. Moisture may also be brought about by damaged mortar joints.
