It’s technically possible in some areas to install your own fire suppression system, but it’s usually not a good idea. Your system must conform to the fire code in your area and will need to pass a rigorous inspection before being activated and deemed safe. Installing a fire suppression system is a complicated job, and making mistakes as a DIYer is likely. Those mistakes can cause you to fail your inspection, which means you’ll have to spend more time fixing the issues or money to have a certified plumber do the work for you. It’s best to hire a professional.

Chimney caps are necessary both from a building safety standpoint in most municipalities and to keep your home protected from a variety of issues. Chimney caps are not only mandated by building code in most areas, but they also serve to keep squirrels, raccoons, and other pests out of your home, as well as snow and rain. Therefore, they help to avoid property damage, making them a worthwhile investment.

You should never block both the top and bottom of your chimney. Proper airflow is essential because the temperature inside the chimney will still fluctuate as your house warms and cools. Moisture can build up without ventilation, leading to dampness in your walls over time. Blocking the top prevents debris and animals from entering, but the chimney still needs air circulation to avoid condensation issues. Allowing the chimney to breathe maintains the health of your home and prevents long-term damage.

Regular professional chimney cleaning and a well-fitting chimney cap are two of the most effective measures to help prevent flue blockages. Annual cleaning keeps the flue from developing a thick layer of creosote. The chimney cap keeps debris out and stops critters from going down your flue for shelter while carrying clog-worthy nesting material.
