Evidence that a Durham home’s chimney requires repairs isn’t difficult to spot.
Bricks, or chips from bricks, on the ground next to the chimney. Staining of remaining bricks in the structure. Evident gaps between bricks. Efflorescence – a white, chalky powder – coating your Durham chimney’s exterior.
Inside a house, staining or efflorescence inside the fireplace is a red flag, too.
Each sign might have a different cause. Hesitating to act isn’t recommended, though. Issues can rapidly worsen. The initial step is a chimney and fireplace inspection by Butler Chimneys, the top chimney sweep company in Durham.
The underlying reason in nearly every chimney issue is water. Sometimes the cause is cracked or damaged flue tiles inside the chimney, which allow moisture to escape into the chimney cavity. If a water heater vents into the chimney, the situation can be far worse. Either way, problems start when moisture has direct contact with masonry.
Gaps in a chimney – from absent bricks, or compromised mortar joints – are major red flags. Durham rains can directly penetrate inside the chimney cavity, making a bad scenario far worse.
The initial step is to address root causes. If flue tiles have lost their structural integrity, putting in a stainless steel chimney liner typically stops internal moisture issues. The damage to the chimney remains, though.
Tuckpointing - grinding out and replacing deteriorated mortar – is occasionally all that’s required. Adding optional ChimneySaver water repellent tacks five years onto Butler Chimneys’ regular five-year warranty, guaranteeing a decade of protection from the elements.
If the source of water leakage is a cracked chimney crown, two options exist. A stainless steel chimney cap can be mounted atop the crown, creating an “umbrella” over the chimney. Or, if the crown is too damaged, a new one is poured.
If a chimney is beyond recovery, a full or partial rebuild is in order. A masonry project takes three to five days; for appliance chimneys, usually one day. You and your Durham neighbors can expect scaffolding to be put up, or a temporary rooftop construction station built.
The chimney is rebuilt with fresh bricks and new mortar to building code height. Butler Chimneys works to match colors of new bricks to originals; bricks can be stained, if needed.
A new 5-inch-thick concrete crown is poured on top. The crown employs a 2-inch overhang to keep water off the new chimney beneath. Your new chimney is as attractive as it is functional!
If you detect indicators of a failing chimney, what’s the issue … and the remedy? Only inspection by a qualified chimney company can find the answers. Time, though, is of the essence – contact Butler Chimneys before additional (or worse) symptoms appear!
