Installing Spider Damper in Prefab chimney

Recently we installed a top mount damper in a prefab fireplace chimney called the Spider Damper.  This is used to replace a damaged or rusted damper part in most prefabs.


First we remove the cap on the chimney to check for installation issues. Then we pull the inner sheve up and out of chimney pipe you see on the right sitting beside cap.

Here we are looking down the chimney and you can see my work light below.  (it about a 24 ft chimney)

Here we have inserted the Spider damper into the chimney liner pipe.  Its called a Spider Damper due to it hanging on the chimney pipe. It hangs down about 10″.

We did have to modify the part that slips into the pipe as it was too long with the spider damper in place.

After we get every thing back together we put top back on and head down the ladder to do inside part.

    Thanksgiving and Christmas holidays are a time for family and friends to get together eat, drink and make merry..

    ALso, if you had another chimney sweep company come out to clean or check your chimney and leave you with a report that says you need thousands of dollars worth of repairs please give us a call.

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


    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" 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

    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.
