Is your fireplace damper open or closed??

With summer time just get ready to start thinking about your fireplace is the LAST thing you are doing this time of year.

More likely you’re thinking about grilling, going to the beach and other fun summer stuff so why are we talking about the fireplace again??

Well something we see with too much frequently is the damper is left open after the last fire of the season or, in some cases, left open during entire heating season.

How can you tell if your damper is open or closed and why knowing is important?

in the picture above you see an open masonry chimney damper and the picture below shows it closed.

Just a bit of FYI.. if you home is 2 story and you leave the damper open and don’t have glass doors the flow through the damper, and this is with fireplace at room temp, can be over 500 feet per Minute.  The means all the heated air in your home, especially the lower part, can be dumped outside every 4-5 hrs.

Now if you have glass doors and they are closed that number is much smaller.

Some folks have commented about how the room with the fireplace as always cold or had cold drafts and sure enough they had not checked the damper and it was open.

Now if you have a warm/hot fireplace the number up the flue is higher by a factor of 3.

I tell folks to get the damper closed soon as possible after a fire. With most dampers you can adjust the handle to where it not open as much. This is not true for every fireplace some, especially pre-fab type, the damper is either open or closed.. no middle ground.

Give yours a check to see open or closed it can help save money during winter keeping it closed when not in use.

.. have a good summer and see you in the future.

Don’t forget we do gas log repairs adn service for you.

    Well a new year is upon us and during this time in late Jan the temps are running above normal. This will end I hear the middle of Feb with temps coming back to normal and COLD..

    We still get a lot of folks calling to ask for a second opinion where another local company was call and they found a LOT of stuff wrong with your 20 plus year old chimney most of the time with a quote of 4-5K or more.

    A lot of the things they "recommend" are to bring your chimney up to 2018/2019 code standards which is not necessary unless you are doing major repairs on the chimney or it is being torn down and rebuilt.

    Chimneys built in the 60 and 70's had different code requirement than a chimney built in 2018/2019.


    PS, If you have gotten a quote for chimney repairs, ie.. you need a chimney liner -liner work, parging smoke chamber etc. or you have been told "you might burn your house down" or "this could create a problem" stuff, that seem HIGH give us a call and let see what we can do for you.
