SPOT THESE 4 SIGNS YOU NEED CHIMNEY MASONRY REPAIR

Chimney masonry repair helps to correct damage and restore the structure to the bricks and mortar of your best chimney. While masonry repair is an essential task to keep your chimney safe, many homeowners don’t know how to recognize the signs that a chimney masonry repair is due. Here we look at 4 key signs that you need a chimney masonry repair.

Mortar Worn Away From Between Chimney Bricks

Weather and wear can first affect the softer mortar that fills the space between each brick or stone. Signs of deteriorating mortar joints include mortar crumbling and eroding from the mortar joints or a complete lack of mortar where it’s worn away between the bricks. Mortar repairs, also known as chimney repointing, involve replacing and filling in the joints of brickwork with new mortar. Chimney masonry repair and repointing should be done in warmer months when the mortar can set up correctly, however small repairs can be made using an accelerant mixed in the mortar during winter months.

Cracks In The Masonry And Mortar

Another sign of chimney masonry damage is visible cracks in the bricks or mortar. This can be caused by prolonged weather damage or wear. It’s important to repair chimney cracks rapidly as a cracked chimney can accelerate damage to the remaining bricks and mortar as well as increasing the risk of chimney collapse. Repointing the chimney may help to replace cracked mortar, but larger repairs such as the removal and replacement of bad bricks or a complete or partial tear down may be necessary depending on the damage.

Spalling Bricks

Spalling bricks are caused when moisture and the freeze/thaw cycle disrupt the structure of the bricks and causes them to fail. This causes the brick faces to pop off when water inside the brick freezes in the winter and expands pushing the brick structure outwards. Many chimneys are built with soft style breaks that absorb moisture out more readily and are more prone to spalling. If you notice spalling bricks on your chimney it’s a sign that your chimney needs masonry repair as soon as possible to prevent further deterioration or collapse.

Leaning or Crumbling Chimney

A leaning chimney can either mean that the foundation of the chimney is not right or that there has been movement between the house and the chimney. This can be a difficult problem to diagnose as the foundation of the chimney must be inspected for stability and safety. In many cases this can lead to the need for the chimney to be torn down and rebuilt. A crumbling chimney can be due to cracked bricks or a cracked crown that hasn’t been repaired. If a chimney has already started to significantly crumble or bricks have fallen, it’s essential to have the chimney inspected as soon as possible. The chimney may need to be removed or rebuilt to prevent further damage to your chimney or home.

While many homeowners can ignore a damaged chimney, particularly if it’s not being used, that doesn’t mean that an unstable chimney doesn’t pose a threat to your home. If your chimney shows any signs of needing masonry repair contact your local chimney sweep or chimney inspections in concord as soon as possible to provide a thorough inspection and diagnosis.
