Chimney fireplace sealing

The way you must seal your chimney fireplace depends on the problems that you have related to it. Inefficient dampers, drafty flues, are common issues of masonry chimneys. Older chimneys also have draft problems.

The hot air that comes from the fireplace is sucked through the chimney and out instead of entering the house and in some situations, central heating is lost due to a poorly sealed fireplace.

Stopping drafts

You can use weatherstripping or high temperature-resistant caulk so seal off any gaps around the fireplace doors that may affect the heat distribution. Also, to properly prevent hot air from escaping, place an inflatable plug in the flue when you don’t use the fireplace, or other draft stoppers and tightly rolled batt insulation.
