Demolition looks simple: take out what you do not want. In practice, it is where most remodels either set themselves up for success or lose a week. The difference is planning what comes out, how it leaves the house, and where it goes.
Before anything is removed, the utilities in the work area need to be shut off and capped: water lines to the old sink or tub, circuits feeding the old lights and outlets, and any gas lines. Walls that might be load-bearing need to be confirmed before they are touched.
Next, protect what stays. Floors along the path out of the house, door frames, stair treads, and neighboring rooms all take a beating during a tear-out. Plastic sheeting, floor protection, and a closed-off work area keep dust and damage contained.
Then think about where the debris goes. A rented dumpster can sit on your driveway for weeks and leaves the loading to you. When the same crew that does the demolition also hauls it away, debris leaves as the work happens and your driveway stays usable.
