Keeping Your Chimney Protected from Soot, Lightning, and Moisture

Though your chimney seems solid and strong, factors like weather, age and use will take a toll on even the most well-made chimneys. It is very important that you maintain it on a regular basis and have it checked by a professional to repair any issue quickly.


The interior of the chimney is often a bigger concern than the exposed side, particularly if the insulation becomes saturated with soot and stops working. Chimneys are supposed to help retain heat on cold nights but with too much soot, there is a risk that they will not keep cold air out and prevent smoke buildup in the home.

Do not wait for soot to narrow the airways. Hire a professional chimney sweep regularly to remove it, as well as any creosote buildup, which is a by-product of incomplete combustion. In very high temperature exceeding 3,000 degrees, it can burst into flames and endanger your property.


Many masonry chimneys are grounded to protect against lightning strikes, meaning it can conduct lightning without significant danger to your home. Metal chimneys are also very good conductors of electricity and may carry electric current without damaging the surrounding structure. They will still need grounding, though, so it’s important to talk to a chimney expert and make sure your home is safe.


Water from rain and snow can weather and decay many types of chimneys. Masonry chimneys are water absorbent and may expand during cold season, contracting as the weather becomes dry again. When the cement starts to show off erosion, pockmarks, cracks and moss, frozen water can penetrate through these openings and put your home and your roof at risk. Be sure to have an experienced chimney repairman come and fix any potential signs of erosion before it poses a danger to your home.

Metal chimneys or stovepipe may be less prone to water damages, but will always be a threat because of the potential for corrosion. You can prevent rust through paint or other steel coating and regular maintenance and upkeep.

Another way to keep moisture out is by sealing the chimney’s exposed side with a one-way moisture barrier. It also helps to install a metal chimney cap to keep birds and rain from entering through chimney hole.

The chimney is important in many ways and protecting it is crucial. For the safety of your property, have your chimney inspected and get the protection it needs. Contact us for professional chimney cleaning and maintenance. We will be there whenever you need our assistance.
