California is known for having earthquakes that can damage your chimney

As residents of California, we are familiar with dealing with earthquakes and the property damage they can cause. Did you know the most common earthquake property damage is chimney collapse? Not only is this true in our state, but also in other areas that suffer earthquakes in this country. The number of chimneys lost every year to earthquake damage is staggering. One reason for this great structural loss is chimneys are often ignored when preparing for earthquakes and the damage they can cause. Weststar Chimney Sweeps would like to tell you more about the effect of earthquakes on chimneys.

How do earthquakes cause a chimney to collapse?

It goes without saying that earthquakes cause the ground to shake resulting in buildings enduring forces to which they are not normally subjected toward. These forces lead to a deterioration of the brickwork and can cause a chimney to collapse. Even minor seismic events can cause this to happen to your chimney, so it’s important to have your chimney routinely checked – especially in seismic hotbeds.

What is the best prevention against chimney collapse during seismic activity?

The chimneys that are most commonly damaged are un-reinforced chimneys, according to InspectAPedia, an online encyclopedia of building and environmental inspection, testing, diagnosis, and repair topics.

What are the dangers of a chimney collapse?

No one can predict which way a chimney will collapse. If a chimney were to collapse on the house, it could be deadly. People have even become trapped inside by a collapsed chimney. Even if the chimney does not fall onto the house, it could fall on a neighbor’s home or on someone outside.

What can I do to prepare my un-reinforced chimney for an earthquake?

You can have your chimney braced, but this does not guarantee it will not collapse. You can also remove the masonry and use a metal flue that is surrounded by a wooden box. This box can be covered with brick veneer above the roof line.

What is the best thing I can do to be sure my chimney is sturdy enough to withstand seismic activity?

The best way to ensure your chimney is safe from earthquake damage is to have it inspected every year by Weststar Chimney Sweeps. We have experience in knowing where earthquake damage can occur and exactly what to look for to be certain your chimney is safe during seismic activity.
