Proof that a Ottawa home’s chimney needs repairs isn’t difficult to spot.
Bricks, or chips from bricks, on the ground next to the chimney. Discoloration of remaining bricks in the structure. Evident gaps between bricks. Efflorescence – a white, chalky powder – on your Ottawa chimney’s exterior.
Inside a home, staining or efflorescence inside the fireplace is a warning, too.
Each indicator might have a different cause. Hesitating to act isn’t smart, though. Issues can rapidly worsen. The initial step is a chimney and fireplace inspection by Butler Chimneys, the top chimney sweep company in Ottawa.
The common factor in nearly every chimney problem is water. Sometimes the cause is cracked or damaged flue tiles inside the chimney, which permit moisture to seep into the chimney cavity. If a water heater vents into the chimney, the issue can be far worse. Either way, problems begin when moisture has direct contact with masonry.
Gaps in a chimney – from absent bricks, or compromised mortar joints – are major red flags. Ottawa rains can directly penetrate inside the chimney cavity, making a bad situation far worse.
The first 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 problems. The harm to the chimney remains, though.
Tuckpointing - grinding out and replacing deteriorated mortar – is sometimes all that’s involved. 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 damaged chimney crown, two options are available. 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 recovery, 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 Ottawa 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 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 notice 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!
