Cold Weather Season and Your Fireplace

Cold Weather Season and Your Fireplace

Colder Weather in Gainesville may finally be here to stay for the winter season.  And for me, that means regular use of my wood burning fireplace! Here’s a great tidbit about Cold Weather Season and Your Fireplace.

I received a great newsletter from Housemaster today.  Thanks Matt Peck, our Housemaster Home Inspector for Gainesville Florida area, for sending these great newsletters to me each month!  One of the articles was about taking care of your home’s fireplace.  I wanted to share this great information!    And if it’s time for you to have your fireplace checked or inspected, you may want to read my previous post about Chimney Sweep Services in Gainesville.

Do you have a Smokey Fireplace? 

The first step in most cases is to arrange for an inspection or cleaning of the chimney flue. A certified chimney sweep is usually the appropriate professional to contact for chimney cleaning or investigation of fireplace or chimney problems. Many sweeps now have equipment to take a video of the chimney flue so that you can see exactly what problems may lie within, as well as to confirm it was cleaned properly.

Here are some possible practical solutions to aggravating smoke problems:

1. Raise the hearth. A fireplace opening that is too large compared to the opening of the chimney flue can lead to poor drafting (the movement of the gases that result from the burning wood up the chimney). By building up the base of the fireplace, the opening will be decreased. To experiment with this approach, a sheet metal hearth can be supported on bricks placed on the existing hearth. If this change improves the draft, the hearth can be raised using firebrick masonry. The hearth extension can also be built up to the same level.

2. Add a canopy hood. An experimental model of a canopy hood can be made of sheet metal and temporarily attached over the top of the fireplace opening. Try various designs and sizes. If the hood works well, a permanent metal hood can be installed.

3. Extend the chimney. The higher the chimney, the better the draft. A good draft is usually provided by a chimney which is 20 feet or more higher than the hearth. If the existing chimney is short a good draft may just not be able to develop. One or more metal chimney sections can be temporarily installed on top of an existing chimney to test whether the draft is improved before a more permanent (and expensive) fix is tried.

4. Trim surrounding trees. Wavering smoke patterns above the chimney may indicate that tall trees are causing a downdraft (air forced down the chimney by the wind). The surrounding trees should be trimmed and/or the chimney flue height extended to prevent this condition.

5. Add a chimney cap or flueguard. If a downdraft appears to affect the exhaust gases, adding a chimney cap or flueguard of metal or stone may help deflect the air before it entering the chimney.

These suggestions for correcting smoking fireplace conditions may be only the first step in some situations. If there are major fireplace deficiencies or the chimney is deteriorated, more drastic measures will be needed. The only practical options in severe cases may be to rebuild the fireplace and/or chimney. A less expensive option would be to retrofit a masonry fireplace or chimney with a gas-fired fireplace coupled with a new metal flue inside the defective chimney – or to use an electric fireplace and seal off the old chimney. Simply maintaining a small fire may help as well.

Note: These tips are only general guidelines. Since each situation is different, contact a professional if you have questions about a specific issue. More home safety and maintenance information is available online at www.housemaster.com.
