How is air from the chimney getting into my home in the first place?

When people weatherize their homes by sealing windows, doors, and any other source of outside air flow, it can create negative air pressure inside the house, which will pull air from the chimney inside your home. No matter what the source of the bad smell in your chimney may be, that odor can come inside your living space as that chimney air flows into the house. Kitchen and bathroom exhaust fans and clothes dryers can also lead to negative air pressure. To solve this problem, you can simply crack a window, close your fireplace damper, install glass fireplace doors, or have a top-mounted damper installed at the top of your chimney. Our experienced chimney sweeps can help you find the best solution for your situation.

What are the causes of smelly chimneys?

  • Creosote: According to the CSIA, the strong, acrid smell of creosote deposits that have accumulated within your chimney gets much worse in the summer when the humidity is high and your air conditioning is being used. If you have noticed the unpleasant odor get worse after a heavy rain, you can be certain that creosote is the culprit behind that stinky smell. Magic Sweep can take care of creosote odors by sweeping your chimney to remove all of the creosote deposits from its walls. Removing the creosote can also prevent hazardous situations such as a chimney fire as this natural compound is extremely flammable.
  • Birds and animals: If you do not have a good chimney cap installed correctly on the top of your chimney, birds and animals can easily go inside to nest. When they leave the nest, birds and animals leave all the materials behind, and this debris can create bad smells inside your chimney. Sometimes a bird or an animal like a raccoon or a squirrel can get trapped inside your chimney and die. If this happens, you can be in for a horribly unpleasant odor. If you suspect birds or animals have gotten into your chimney, call Magic Sweep for our assistance. We can help you pick out the perfect chimney cap to keep this from occurring again and properly install the cap for you to prevent animal invasions and water leaks.
