Chimney Repair in Boca Raton

Chimney Repair

Most chimneys are constructed using wood framing, wire lath and a stucco covering. Over time, small cracks can form in the stucco finish allowing water in and begin rusting the wire lath. Rusting wire lath in turn swells and pops the stucco, making even bigger cracks. This condition is called spalling and it allows more and more water in and causes the wood framing to rot. So, a chimney repair can become a little complex. lets walk through the process.

Chimney Repair Explained

Spalling Chimney in Boca Raton


In the image to the left, you can see that the stucco has completely fallen off of the wire lath. The wire lath is very rusted and the wood structure behind is rotted 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. After we rebuild chimneys, we recommend the stucco be painted every three or four years in order to make sure no small cracks form in the stucco again and cause a repeat of the problem.



Applying Stucco on a Chimney Repair

Once all of the rotten wood and rusted wire lath is completely replaced, the process of applying new stucco begins. There are three coats of stucco to be applied on chimneys. There is a scratch, brown and finish coat. There needs to be ample drying time between each layer and so these repairs can span several days and trips. When it comes time to paint the new stucco we refer to it as “thirsty” because the first coat of paint soaks in the stucco like its a sponge. It takes several coats of paint to get a good finished look.


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
