Yes, you can close off a fireplace both temporarily and permanently with extremely wide price ranges. Temporary solutions involve fireplace plugs that can be inflated to block air and deflated to open the fireplace, covers, and boards. Permanent methods of shutting off fireplaces usually involve bricking up the fireplace or covering it with drywall. No matter the method, it’s probably best to hire a professional.

A chimney requires both a cover and a cap, but these parts often get confused with one another. A chimney cover seals the top of the chimney around the flue pipe to prevent water from entering the chimney. A chimney cap is a piece that sits above the flue to prevent animals, debris, and water from entering the flue.

When a carbon monoxide alarm goes off, you should always take it seriously. Infrequent and occasional chirps often point to a low battery, a faulty device, or dust buildup (this usually affects smoke detectors and not standalone CO detectors). A continuous alarm signals an emergency, and you should immediately evacuate and call 911. When it comes to carbon monoxide in your home, it’s better safe than sorry.

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.
