Proof that a Cambridge 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 – coating your Cambridge chimney’s exterior.
Inside a home, staining or efflorescence inside the fireplace is a red flag, too.
Each indicator might have a different cause. Hesitating to act isn’t advisable, though. Problems can quickly worsen. The first step is a chimney and fireplace inspection by Butler Chimneys, the top chimney sweep company in Cambridge.
The underlying source in nearly every chimney issue is water. Often the cause 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 situation can be far worse. Either way, problems start once moisture has direct contact with masonry.
Gaps in a chimney – from absent bricks, or failed mortar joints – are major red flags. Cambridge rains can directly leak 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 generally stops internal moisture issues. 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, guaranteeing 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 damaged, a new one is poured.
If a chimney is beyond restoration, 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 Cambridge neighbors can expect scaffolding to be put up, 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 beautiful as it is functional!
If you spot indicators of a deteriorating chimney, what’s the problem … and the remedy? Only inspection by a qualified chimney company can find the answers. Time, though, is of the essence – contact Butler Chimneys before more (or worse) symptoms appear!
