The cost to replace a chimney damper ranges from $160 to $520, depending on the type of damper and the complexity of the installation. If you're looking to repair an existing damper, expect to pay around $100 and $225, depending on the extent of the damage and your location. Hiring a professional ensures proper installation or repair, which can help maintain energy efficiency and prevent drafts, making it a worthwhile investment for long-term savings.

You can close up a chimney instead of demolishing it. Homeowners often go this route because the cost of removing a chimney, especially a structurally important chimney, can be expensive.

Properly closing up a chimney involves closing and sealing the damper, installing a chimney cap damper, and sealing the fireplace opening with a door or bricks. The cost to seal and cap a chimney is around $500 to $650—significantly less than the average chimney removal cost.

Some disadvantages of a wood-burning stove include the heating time, which can take about an hour before a cold stove is warm enough to feel any heat, and fuel sourcing. Homeowners with wood stoves must chop or buy their firewood and store it properly to fuel the wood stove.

In addition to flashing, a roof cricket can help divert water around your chimney so that it drains properly off your roof. It’s shaped like a double triangle and is installed behind the chimney so that falling water spills evenly down each side. This helps prevent water from accumulating behind your chimney, which can increase water damage and the risk of leaks. 

The International Building Code (IBC) requires cricket installation if a chimney built after 2012 measures over 30 inches in width. Chimneys constructed before that date are typically grandfathered in and aren’t required to have crickets installed.
