Question DetailsAsked on 1/6/2017

Is it possible to flatten a diagonal fireplace in a rowhome?

I just bought a 100 year old rowhome that has a diagonal fireplace that's built in the back left corner of the living room towards the center of the house. I believe that the chimney goes straight upwards to the roof. I want an open concept, but leaving the fireplace in it's current position kills the flow. I was wondering if anyone has ever flatten out their fireplace and what would be the estimated cost of having it flattened out? Thanks!

You would need to have it looked at by a Fireplace Repair mason - though moving it away from the current location (as opposed to maybe just flattening it to one wall but still in the corner) is a MAJOR change. Even assuming your chimney only serves that one fireplace, I would guess $1000 minimum and maybe much more - and if it services multiple fireplaces or units then possibly about as much as a new chimney - several thousands minimum.

One other alternative would be eliminating the fireplace (with or without taking the chimney out as well), and putting a new "ready-set" type fireplace where you want it - uses a "fake" chimney with metal ducting inside as the flue. Or go with a direct-vent fireplace (wood or gas) or free-standing fireplace venting directly outside. Course, if you do that, unless you are a SERIOUS wood burner in a large fireplace, just go with gas unit and save a lot of energy, because basically speaking and in row houses especially, fireplaces commonly actually consume more energy fro the house (in heated air drawn up the chimney) than they produce.

My recommendation - even though they are available (though in my opinion should be outlawed) do NOT use a gas fireplace/stove which does not have fresh air intake from and venting to the outdoors - both for energy efficiency reasons, and also because venting into the house dumps a LOT of combustion moisture (as well as odors) into the living space.
