Chimney Repair in Boca Raton

Chimney Repair

Chimneys are constructed using wood framing, wire lath and a stucco covering. Sometimes they can be concrete, but not often. Small cracks can form in the stucco finish over time. Water rusts the wire lath. Rusting wire lath in turn swells and pops the stucco, making even bigger cracks. When stucco exhibits these characteristics it is called spalling. It allows more and more water in and causes the wood framing to rot as well. So, a chimney repair can become a little complex. Lets walk through the process.

Chimney Repair Explained

Spalling Chimney in Boca Raton

Spalling

In the image to the left, you can see that the stucco has completely fallen off of the wire lath. Rusting wire lath has resiulted. Wood behind is rotten and completely missing. Unfortunately, this is a very common occurrence. In this case, the homeowner paid several contractors to repair it but the problem persisted because they simply tried to seal the stucco instead of replacing it.

Rotten Wood

The next image shows the rotten wood behind the wire lath and stucco. In many cases the wood is completely missing. We use pressure treated lumber when repairing chimney structures to ensure the rotten wood can’t come back.  We recommend painting the chimney every three or four years after we have completed repairs. This prevents small  cracks from forming in the stucco again and cause a repeat of the problem.

Applying Stucco on a Chimney Repair

New stucco application begins when the rotten wood and rusted wire lath is completely replaced. There are three coats for stucco application. These are scratch, brown and finish coats.  Each layer of stucco needs ample drying time between each coats . As a result, these repairs can span several days and trips.

Painting New Stucco

We call new stucco  “thirsty”. The first coat of paint soaks in like water to a sponge. It takes several coats of paint to get a good finished look.  It takes stucco somewhere between 45 and 60 days to cure. During this time the PH stabilizes. Paint should not be applied until this takes place.

Chimney Caps, Flues and Spark Arrestors

The chimney "flue" is the pipe within the chimney that carries the smoke from the the fireplace up and out. On the top of the flues or square cap. This "flue cap" can bee seen at the very, very top of the chimney. The flue cap has two functions. First, the flue cap prevents rainwater from entering in to your home. Second, the flue cap serves as a "spark arrestor", preventing fire embers to rain down outside of your home and causing a potential fire.

The chimney cap is the metal cap flashing on top of the chimney structure. We make our chimney and flue caps with aluminum. Aluminum does not and lasts much longer than galvanized metal caps
