How can I tell if my Chimney/Fireplace is Masonry (brick) or a Prefab?

We have people calling the office speaking with Karen to set up a time to clean their chimney. One of the questions we ask during the conversation:  “Is your chimney brick or prefab?”

I can only imagine the expression on the other end of the phone as some are not sure. To help, we have put together this guide on the difference between brick and prefab chimneys.

If your house has siding, either wood, hardyplank or vinyl that extends up the chimney as well, you most likely have a prefab fireplace.

In the picture on the left the house has siding and brick and the chimney is made of brick.. This unit is a brick or masonry chimney.

In the picture to the right it appears to be the same siding with brick chimney, at least until you look to the top.



2014-09-11 12.20.34In this picture you see the top of the chimney which is covered in metal and has a round pipe coming out.. This is a prefab fireplace with metal flue pipe inside a brick veneer on the unit. Now this chimney is at a condo complex and this is the end unit.. this is somewhat common to do while the units on interior part of the block with be siding unit like this

Most brick chimneys have flue liners sticking out the top like this. (this

    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.
