Proof that a Merton home’s chimney needs repairs isn’t hard to find.
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 Merton 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 smart, though. Issues can rapidly worsen. The first step is a chimney and fireplace inspection by Butler Chimneys, the top chimney sweep company in Merton.
The underlying reason in almost 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 absent bricks, or compromised mortar joints – are major warnings. Merton rains can directly leak inside the chimney cavity, making a bad scenario far worse.
The initial step is to address root causes. If flue tiles have lost their structural integrity, putting in 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 occasionally all that’s involved. Adding optional ChimneySaver water repellent tacks five years onto Butler Chimneys’ regular five-year warranty, promising 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, forming an “umbrella” over the chimney. Or, if the crown is too deteriorated, a new one is poured.
If a chimney is beyond saving, a full or partial rebuild is in line. A masonry project takes three to five days; for appliance chimneys, usually one day. You and your Merton 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 below. Your new chimney is as attractive as it is functional!
If you spot 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 additional (or worse) symptoms show up!
