While a hot fire can help heat up and loosen tar within your chimney, making it a recommended step before using a creosote log, it will not burn off significant existing buildup on its own. Attempting to remove built-up creosote with a hot fire is dangerous and can cause a chimney fire. For safe and effective removal of caked-on creosote, the best approach is to hire a professional chimney sweep.

No. Removing the cause of concern will only lead to deeper concern. You cannot use any fire-powered appliance like a fireplace or furnace without an escape route for the smoke and fumes. If you remove the flue intending to repair or replace it, you should only use the fireplace, wood stove, or furnace once the flue is in working order. If you cannot replace the flue you have removed, call a chimney repair professional immediately.

Certain fireplace repairs will require that your contractor is licensed, including anything that involves moving, installing, or repairing gas lines. In that case, your professional will need to be a certified plumber. You can use Angi’s licensing lookup tool to confirm that the company you’re hiring is properly licensed. Most states don’t have specific license requirements for other fireplace repairs, but most demand at least a general contractor’s license. It’s also a good idea to look for companies certified by the National Fireplace Institute, as those pros tend to be more qualified to carry out the repair.

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.
