Chimney Repair

Chimney deterioration is a natural process occuring due to exposure to rain, snow, ice, wind, freezing and thawing, age, and more. Over time, the bricks and mortar joints in most masonry chimneys will deteriorate. Chimney Crowns that keep water out of the top of the chimney will crack, and some bricks absorb more water than others. There are a number of reasons your chimney exterior may be in need of repair.

Tuckpointing focuses on just the mortar joints that hold the chimney’s bricks together. The mortar that has started to crumble must be addressed before serious structural compromise happens. Tuckpointing involves scraping or grinding away old, decayed mortar and replacing it with fresh new mortar. It doesn’t require disassembling and then reassembling the chimney or sections of it. When performed by an experienced chimney services professional, tuckpointing will restore your chimney’s strength and give it more years of life and performance.

The National Fire Protection Agency (NFPA) recommends getting your chimney inspected and cleaned by a certified professional at least once a year. Flammable elements called creosote deposits can accumulate in your chimney over time, making it prone to chimney fires (burning uncontrollably at 2000° F)! Thankfully, timely cleaning of the fireplace and chimney flue can help avoid this hazard.

Any time your chimney structure is weakened or compromised, some level of rebuilding may be necessary. If your chimney is missing mortar in spots and the bricks are loose, you probably need at least a partial rebuild. Many times a clay chimney flue that is not in use (dummy flue) is filled in with concrete which causes major damage to the crown and chimney over time. Or if the crown of the chimney does not overhang, water and ice can destroy your chimney. Another problem is an unlined chimney or cracked flue tiles.

In some cases, you may notice that the surface layer of the bricks in your chimney have begun to flake off. This type of deterioration is known as spalling and typically occurs as the result of moisture in the bricks freezing and thawing. The bricks in the chimney may become saturated with moisture from rain or snow, and the water inside the bricks often freezes during the winter months. The frozen water inside the brick expands slightly and the brick begins to crack. The bricks freeze and thaw repeatedly, continuing the process until the front of the brick begins to flake off. To prevent spalling, the bricks used on the outside of a chimney are usually harder and less likely to absorb moisture. However, in some cases, a softer brick is accidentally placed on the outside where it is vulnerable to moisture issues. A brick chimney may also experience spalling if a severe problem with water intrusion occurs.

Waterproofing is another way to prolong the life of your chimney. And when we rebuild, we shop for the bricks close to the original color and texture. You can even come shopping with us!
