Chimney cap can help prevent smoky rooms

Q. I want to know how to prevent a fireplace from sending smoke back into the house. The chimney was extended, but the problem still exists.

A. There are a number of chimney caps that you may want to consider. They are usually available at your local hardware store or from a fireplace and stove shop. They are designed in several configurations, each to address different down-draft situations. It may be best to visit a local shop, and describe the details of you geographic location, surrounding factors such as tall trees, other structures and wind direction to help determine the fix.
