Indication that a Saint Martins home’s chimney needs repairs isn’t hard to identify.
Bricks, or chips from bricks, on the ground next to the chimney. Discoloration of remaining bricks in the structure. Visible gaps between bricks. Efflorescence – a white, chalky powder – on your Saint Martins chimney’s exterior.
Inside a house, staining or efflorescence inside the fireplace is a warning, too.
Each symptom might have a different cause. Waiting to act isn’t wise, though. Issues can rapidly worsen. The initial step is a chimney and fireplace inspection by Butler Chimneys, the top chimney sweep company in Saint Martins.
The underlying source in almost every chimney issue is water. Often the culprit 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 when moisture has direct contact with masonry.
Gaps in a chimney – from missing bricks, or failed mortar joints – are major warnings. Saint Martins rains can directly leak inside the chimney cavity, making a bad situation far worse.
The first step is to confront root causes. If flue tiles have lost their structural integrity, installing a stainless steel chimney liner generally 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’ standard five-year warranty, promising a decade of protection from the elements.
If the source of water leakage is a cracked chimney crown, two options are available. A stainless steel chimney cap can be mounted atop the crown, creating an “umbrella” over the chimney. Or, if the crown is too weakened, a new one is poured.
If a chimney is beyond restoration, 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 Saint Martins neighbors can expect scaffolding to be put up, 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 below. Your new chimney is as beautiful as it is functional!
If you identify indicators of a deteriorating chimney, what’s the issue … and the fix? 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!
