Durham Chimney Repairs Needed? It’s Not Difficult to Identify the Warnings

Evidence that a Durham home’s chimney needs repairs isn’t difficult to identify.

Bricks, or chips from bricks, on the ground next to the chimney. Discoloration of remaining bricks in the structure. Obvious gaps between bricks. Efflorescence – a white, chalky powder – lining your Durham chimney’s exterior.

Inside the house, staining or efflorescence inside the fireplace is a warning, too.

Each indicator might have a different cause. Hesitating to act isn’t recommended, though. Issues can quickly worsen. The first 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 problem can be far worse. Either way, problems start once moisture has direct contact with masonry.

Gaps in a chimney – from missing bricks, or failed mortar joints – are serious warnings. Durham rains can directly penetrate inside the chimney cavity, making a bad scenario far worse.

The first step is to confront root causes. If flue tiles have lost their structural integrity, installing a stainless steel chimney liner usually stops internal moisture problems. The damage to the chimney remains, though.

Tuckpointing - grinding out and replacing deteriorated mortar – is sometimes 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 damaged chimney crown, two options are available. A stainless steel chimney cap can be mounted atop the crown, forming an “umbrella” above the chimney. Or, if the crown is too damaged, a new one is poured.

If a chimney is beyond restoration, a full or partial rebuild is in order. A masonry project runs three to five days; for appliance chimneys, usually one day. You and your Durham neighbors can expect scaffolding to be erected, or a temporary rooftop construction station built.

The chimney is reconstructed 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 beautiful as it is functional!

If you detect symptoms of a deteriorating 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 show up!
