Saint Lawrence Chimney Repairs Needed? It’s Not Difficult to Find the Symptoms

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

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 – lining your Saint Lawrence chimney’s exterior.

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

Each symptom might have a different cause. Hesitating to act isn’t recommended, though. Complications can quickly worsen. The initial step is a chimney and fireplace inspection by Butler Chimneys, the top chimney sweep company in Saint Lawrence.

The commonality 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 issue 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. Saint Lawrence rains can directly leak 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, putting in a stainless steel chimney liner usually stops internal moisture issues. The harm to the chimney remains, though.

Tuckpointing - grinding out and replacing deteriorated mortar – is sometimes all that’s needed. 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” over the chimney. Or, if the crown is too weakened, 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 Saint Lawrence 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 problem … and the remedy? Only inspection by a qualified chimney company can tell. Time, though, is of the essence – contact Butler Chimneys before additional (or worse) symptoms show up!
