Learn how to safely demolish a wall with this free DIY guide. These are step by step instructions for easily removing conventionally framed walls.
Concerning All Walls
By nature walls are primarirly used for supporting overhead loads. It is absolutley necessary to temporarily support these loads. For example, to demolish an exterior house wall, first prop up the load of the ceiling and roof with by tacking up a two by four parallel with the wall and about two feet away. Do the same on the floor then put studs in about two feet apart. Do not assume the floor is rock solid. Framed floors have in them special beams to support the load of walls. Typically a framed floor will not properly support the load of an overhead story by itself. If their are any concerns, then build another temporary wall under the floor itself. Better safe than sorry. These temporary supports are worth the effort. They will support the ceiling and roof until the wall is reserructed.
Mold is an issue of serious concern. If mold is present, then adequate safety gear must be worn. Reduce the danger of the the airborne particles by first killing the mold with a solution of bleach and water. Mold is very dangerous. If it is visible, then it is being inhaled.
Disconnect power and water supplies travelling through the wall. Just because no outlets, light switches, or plumbing fixtures are mounted on the wall, does not mean there are no wires or pipes unseen.
Demolishing a Framed Wall
Remove any switch or outlet covers. Score any caulked joints on trim and baseboard with a utility knife. Carefully remove the trim and baseboard with a flat bar. Remove any doors or windows.
Remove the drywall or other wall covering. This is messy. Keep as clean of a work area as possible. Do not sink a reciprocating saw in blindly hoping there are no wires or pipes behind the drywall. It is not that big of a deal just to knock a hole in the drywall and pull it off a little peice at a time.
Assuming that any loads supported by the wall are properly supported and all wiring and pipes are removed, then take out the studs one at a time. Keep an eye overhead for any sign of the building falling down!
Rebuild the wall as soon as possible. Those temporary supports are just that; temporary. Check on them from time to time with attention on the straightness of the studs. They will bend when overloaded.
