Most homeowners never think about masonry chimney maintenance beyond the usual annual flue cleaning. Unfortunately, ignoring your chimney can cost you big! Problems that are addressed early on can prevent bigger issues down the road; small repairs are far less costly than larger ones. The certified pros at Old Hat Chimney Service are here to handle all of your masonry repair needs.
Is Crumbling Mortar a Problem for You?
Your chimney is exposed to the elements on the outside and the heat from your firebox on the inside. As a result of this two-front attack, the weathering process is sped up. As such, it isn’t atypical for your mortar to begin to crumble and/or break away. This leaves open areas between the bricks, which exposes even more surface area to these weathering agents and processes. Repointing your chimney might be recommended. During this process, the damaged, old and loose mortar on your chimney is removed from the joints between the bricks and replaced with new mortar.
Has your Chimney’s Crown Seen Its Better Days?
Your chimney crown is a reinforced concrete cap placed over the top of your brick and mortar chimney. A properly constructed crown sheds water and serves as a protective covering for your chimney against harsh weather. Your chimney crown is exposed to the same elements that wreak havoc on your chimney itself. As such, it can eventually crack or break and need to be replaced. The replacement will either be cast-in-place (a form is placed on the top of your chimney and filled with cement to the exact specifications required by your particular chimney) or precast (a prefabricated unit that is placed atop your chimney).
Are the Bricks in Your Chimney Cracking or Spalling?
When chimneys spall, it’s a sign of severe moisture penetration. Spalling—the flaking off of a brick surface—is evident when the face of the masonry is missing. Pieces of bricks may be found on the ground or on your roof. Damage can be increased if your crown isn’t poured with an overhang/drip edge, as water that is diverted is allowed to flow straight down the face of your chimney. Spalled bricks can’t be repaired and must be replaced.
