    Case Study: Chimney Damper Removal

 
        Before and After

   

 
    The Assignment:
        Remove enough of the fireplace that the wall can be flat.
        Remove the mantle, brick veneer, remaining plaster, damper.
        Carefully remove supports and install new supports.
        Keep the environment clean, protect the floor.
        Prepare the wall for dry-walling to hide the old fireplace.

 
Starting
Before starting demolition, the floor is protected with impermeable nylon tarps,
heavy canvas drop sheets, and thick moving blankets are laid on top.
The room is sealed with plastic, and a wet/dry vac is used frequently.
Debris is bagged and taken to a dump bin outside

 
Damper-MantleOff
The mantle is carefully removed, to be used in a cottage.
The brick veneer surround is being removed, bagged.

 
Progress
We remove surround bricks, exposing support bricks, blocks, inside.

Plaster Chiselled Off
Wire mesh, cement and plaster had covered the wall.
We need clearance for new dry wall to cover this space.

Damper Exposed
The chimney stack above the fireplace depends on lower bricks, blocks.
We carefully remove enough bricks to allow the damper`s removal.
New bricks and blocks are inserted after to rebuild the upper load point.

Front Columns Being Removed
The final bricks and supports are being removed to make the wall flat.
You can see new blocks inserted in the far side to rebuild the support.
Bench Built, Insert Installed
The damper is out, enough bricks and blocks removed.
The new drywall can now fit within the existing crown molding.
