A Top Mount Damper is installed on top of your chimney flue. It locks shut, keeping your fireplace warm, dry and secure, and it is a low-cost solution to replacing rusted, worn-out throat dampers. It reduces the load on heat and air-conditioners and dramatically reduces noise from the outside.

Fireplace performance improves, and cleaner burns reduce pollution. We have installed many Top Mount Dampers and have gotten great results. Modern houses are more weathertight with better sealing around doors and windows. Clothes dryers, bathroom vent fans, and range hoods all pull air out of your home, creating negative pressure inside your home. The easiest place for outside air to enter is down the chimney.

That smoky smell is coming from the chimney along with the cold air. A Top Mount Damper is made to seal the chimney at the top to help prevent air from entering. This helps make the area around the fireplace more comfortable and reduces smells.

Installation of Top Mount Dampers is generally $45.00-65.00 (Raleigh, NC-area only).
Call Chimney Keepers at 919-772-8110 for more information.

Each damper kit comes with a 50-ft. stainless steel cable, chimney top adhesive, mounting bracket for the firebox and lifetime warranty to the original owner.

    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.

  • Woodburning and gas burning fireplaces. Are they ready for winter.

    Is your Fireplace or Gas Logs ready to go.. If not or for a service give us a call.

    In a power outage a fireplace or gas logs may be your only form of heat so make sure they are working in top form. Give us a call to set up appt 919-772-8110

    have a good week

    PS: if you do NOT have a Carbon Monoxide detector and you have gas logs.. GET ONE.. NOW... I recommend the combo CO / Smoke battery powered detectors at Lowe's Home depot or most hardware stores..

    If yours are over 10 yrs old replace it.. (there's a date on back) If there is not a date of manf on back GET rid of it.
