If your chimney is leaking in Marietta, GA, you need to fix the problem as soon as possible. A leak could lead to structural damage, mold growth, and a number of other problems. Watch for the following 5 signs that you may have a leak that needs to be taken care of as soon as possible:

Cracks in Mortar

Check the mortar joints and bricks for any signs of cracks. The cracks will allow water into the chimney. If your chimney is located in a shaded area, you’ll have trouble drying it out so the moisture will stay around and continue to damage your chimney. If you’re wondering about whether your mortar has cracks in it or if there is a lot of moisture in it, you can perform a Masonry Absorption Test (MAT). This test will tell you how much water has been absorbed into the masonry material.

Damaged Wood Siding

If you have wood siding along the exterior of your home, you need to look for signs that it’s deteriorating. Over time, any loose knots will come off the side of your home, making it easy for moisture to seep into your home. Some wood siding will even split as it gets older. If you notice any of these issues, you should replace your siding as quickly as possible.

Cracked Chimney Crown

The chimney crown is placed on top of your chimney to prevent water from getting into your chimney. If it gets cracked, it will have a hard time keeping water out. Look for signs of cracks, which could be the cause of your leak. The cracks should be filled or the chimney crown repaired or replaced to remedy the problem.

Cracked Fireplace Flashing

The fireplace flashing is typically made from aluminum. It surrounds the chimney and prevents water from getting inside. If there are any cracks in your fireplace flashing, similar to the chimney crown, it could be letting in water. Have the flashing repaired or replaced as soon as possible.

Lacking Chimney Cover

A chimney cover goes on top of your chimney to prevent birds, water, debris, and other things from getting inside. If you don’t have a chimney cover, rain can pour into your chimney. Purchase a chimney cover and have it properly installed to start taking advantage of all that it has to offer you.
