Question DetailsAsked on 7/28/2016

How much will it cost to remove a whole chimney

The chimney is located on the right side of a 2 story house. Its falling in and I would like it removed. The house is heated by oil, so there is a oil furnace. I will be converting it to central air and heat.

Cost depends a LOT on whether the chimney is a "bolt-on" on the face of the house or the house wall framing ties into it or it is interior to the house, whether all brick or reinforced concrete with brick facing, etc - and of course the type and fanciness of the interior finishes that will be covering the holes in the floors and the ceilings and walls where the chimney and fireplaces and hearths used to be.

And a major factor, primarily in pre-WWII houses but some later ones too, is whether the chimney provided the end support for structural framing for the house - in some cases floor beams and walls and such are supported on the chimney wherre they intersect it, so of course removing the chimney and re-supporting or replacing framing can greatly increase cost - especially if the removal means floor beams are now too short to reach the outer wall so have to be spliced or replaced.

Commonly - $1000-1500 rough ballpark will handle the actual removal part - more into the $1500-2000 range if it extends clear into the basement as a mass structure that also has to be removed, and even more if it forms part of the foundation so removing it (like to frees up room for a vinished basement) means replacing with new foundation and wall.

Then the rehab work to fill in the holes - commonly at least a couple thousand, and for situations where the holes in the floor where the chimney and hearth used to be cannot readily be filled with matching material because matching material cannot be found, so the entire floor covering has to be replaced in those rooms, can run into the $6,000-10,000 total job range without extreme trouble - especially in houses with multiple or interior (central to house) fireplaces feeding to one chimney and hardwood floors.

While some Masons and Demolition companies will do the demo, you invariably have structural issues to put in place as it is taken out, so you need a Remodeling - General Contractor to handle the demo (which may be done by a sub), the reframing, new interior finishes, filling in wall gaps with wall and insulation and siding, etc.

Be prepared in your mind whether you want continuity in the floor, wall, and siding surfaces - or if you can accept an accent contrast there if not readily matched.

One other sometimes cheaper alternative with exterior wall chimneys that do not support the house framing - replace the deteriorated brick/concrete fireplace with a "ready-set" type unit, which can have wood-burning fireplace, or a wood or pellet or gas insert in it. Is a wood-framed blockout or "chase" on the side of the house which is sided like the house, and has a double-walled flue inside it - can even have fake brick put it on entire surface or only on above-roof part to make it look like a real chimney from a distance. Can be made to take up basically the same wall space as the chimney so greatly reduces the amount of rehab work needed to fill in the old chimney space, and gives you a wood stove or gas fireplace in the house potentially significantly cheaper in cases where matching interior finishes is difficult. Cann also retain the added value of a fireplace to the house at resale time, in areas where fireplaces raise house values.
