Bethesda Chimney Repairs Needed? It’s Not Hard to Spot the Warnings

Proof that a Bethesda home’s chimney requires 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 – on your Bethesda chimney’s exterior.

Inside the home, discoloration or efflorescence inside the fireplace is a red flag, too.

Each sign might have a different cause. Waiting 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 Bethesda.

The underlying reason in nearly every chimney issue is water. Often the culprit is cracked or damaged flue tiles inside the chimney, which allow moisture to seep into the chimney cavity. If a water heater vents into the chimney, the problem can be far worse. Either way, problems start when moisture has direct contact with masonry.

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

The first step is to address root causes. If flue tiles have lost their structural integrity, installing a stainless steel chimney liner generally stops internal moisture problems. The harm 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’ standard five-year warranty, guaranteeing a decade of protection from the elements.

If the source of water leakage is a damaged chimney crown, two options exist. A stainless steel chimney cap can be mounted atop the crown, creating 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 line. A masonry project runs three to five days; for appliance chimneys, usually one day. You and your Bethesda neighbors can expect scaffolding to be erected, 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 features a 2-inch overhang to keep water off the new chimney beneath. Your new chimney is as attractive as it is functional!

If you identify indicators of a failing chimney, what’s the issue … and the remedy? Only inspection by a qualified chimney company can tell. Time, though, is of the essence – contact Butler Chimneys before more (or worse) symptoms show up!
