Knocking Out A Wall Instructions

  • Wall Demolition

    You can often expand your living space by removing non-weight barring walls. While demolishing walls can be tricky, a little pre-planning and the right home protection and safety equipment can help you avoid the pit falls of dust irritation, ruining moulding, trim, floors and doors, and other expenses and aggravation.

  • Overview

    The basic steps to completing this project are to first remove furniture and protect floors, doors, moulding and trim where you plan to work. Determine if you're tearing down a load-bearing wall and properly support it if you are. Tear down the wall slowly and carefully and in the reverse process that it was constructed. Then, clean up and make necessary repairs to the floors, walls and ceiling.

  • Prepare the Room

    Prepare the room to minimize risks and expenses. Before demolishing walls that contains wiring, always shut off the electrically first. There will be plenty of construction dust and debris so remove or cover up furniture, and cover the doors with plastic and masking tape. Open the windows to exhaust some of the dust. And consider protecting easily damaged floors with drywall, it's not that expensive and it does a better a job than plastic sheeting in protecting against sharp objects.

  • Wear Safety Equipment

    Dress for the job at hand. Plaster dust is irritating to the eyes and lungs so wear safety goggles and a dust mask. Heavy boots or shoes will protect you from nails and other sharp debris.

  • Determine Whether It's Load-bearing Wall

    It is critically important that you know beforehand whether you are planning to demolish a load-bearing wall. To find out, remove a small portion of wall and ceiling and to see if there are double top plate on the wall, or if the joists above meet over wall, or take note of the joists sizes above and their loads and consult span tables which are available at your local building department to see if the joists need a barring wall. If they do, you will have to make up for the wall's supporting function by installing a temporally support while you are working and a replacement wall or header when the job is completed.

  • Remove Trim

    To demolish a wall, you basically reverse the construction process. First you remove the trim or molding, but try to preserve it for future projects. Use a nail puller or reciprocating saw with a metal cutting blade to cut through the nails from behind the molding to avoid harming the finish. Doorjambs can be removed the same way after the casing is removed.

  • Remove Fixtures

    To remove wall fixtures, first turn off the power if you haven’t already done so. Then unscrew wall fasteners and disconnect the attached wires. Be sure to put electrical tape or wire nuts over the bare ends of the wire before turning the power back on.

  • Remove Plaster

    To remove plaster cut along the corners of the wall with your reciprocating saw so plaster from other walls and ceilings will not be affected. If the corners are reinforced with wire mesh, cut with a metal cutting blade in your reciprocating saw.

  • Remove Plaster (cont.)

    If your wall is covered by button board with a plaster coat or standard drywall, pound a hole in the wall from which you can leverage a crowbar for pulling off the plaster or drywall. For lathe and plaster, first knock the plaster off the lathe with a small sledgehammer. Be careful to rap only hard enough to break the plaster, not the lathe. After the plaster is removed, take a claw hammer or crowbar and pull the lathe off. Doing these two operations separately makes the debris much easier to handle.

  • Reroute Plumbing

    Next, take out any plumbing lines. Freshwater pipes in the wall will have to be cut and capped out of the way or rerouted. Since proper draining is so critical in the case of wastewater, you should hire a professional plumber to reroute wastewater pipes.

  • Reroute Electrical

    If there are electrical lines or boxes in the wall, they must also be taken out and remove any conduit to the point that it is no longer in the wall. Next, reinstall boxes out of the wall of the wall and reroute electrical lines. Finally, put wire nuts over the ends of the conductors and the cover over the boxes. For details on how to make new electrical connections or how to install switches and plugs, please see our electrical tutorials.

  • Remove Studs

    To bring the studs down, knockout any blocking and cut along the joint between the stud and the plate with a reciprocating saw. It may also be possible to knock the studs loose by hitting them at the base parallel to the wall and pulling them off the nails on the top plate. Finally, pry up the top and bottom plate with a crow bar. To avoid damaging the floor with your crowbar, first slip a piece of scrap wood under the bar.

  • Finish Room

    Finish the room by using skills described in other tutorials, including those for electrical work, floor finishing and the installation of new drywall on wall and ceiling. The clean up can be as tough to tackle as the job itself. While an industrial strength shop vacuum can come in handy, don't try to clean up plaster dust and debris with an ordinary household vacuum, they're just not built to handle such heavy duty.
