When You Contact A Minneapolis Chimney Repair Contractor

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.

If you have capping structures that are missing or defective, you should have them repaired or replaced. The capping structure is found at the top of chimneys and helps in preventing moisture from penetrating inside. If you have moisture that is entering chimneys, you will be encouraging many problems.

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.

Any good mortar does not leave a mark when you run a screwdriver across it. However, bad mortar falls away and leaves a gouge or a small depression where the screwdriver crosses as it peels or flakes away and falls. After checking the mortar outside, you may want to make sure that you check the mortar just below the roofline.

The crown of your chimneys offers a second line of defense against water. Usually, a crown is that concrete or mortar slab which is poured on top of every chimney. It is about 2 by 3 inches. It is this crown that covers the upper most courses of bricks making your chimneys and it surrounds the flue tiles at the top. A crown is needed not only for aesthetic appeal but also for protective purposes.

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.
