There are countless reasons you may need to cut into a ceiling.
If your home was built properly, you likely have insulation between the ceiling and the floor located above the ceiling. This insulation helps keep the house warm in the winter and cool in the summer. Having insulation above the ceiling does not make it more difficult to cut an access hole for installing light fixtures or for gaining access to electrical lines or plumbing.
Instructions
1. Locate the breaker that controls the section of the house where you plan to complete the work. Turn the breaker off. Doing this will protect you in the event you cut into an electrical wire buried in the ceiling.
2. Scribe the outline of the access hole you plan to cut onto the ceiling with a pencil. If you plan to install a junction box or electrical box, place the box against the ceiling and trace around that.
3. Shove the tip of a keyhole saw straight into the ceiling on the line you scribed.
4. Saw through the drywall. Press the saw into the ceiling as shallowly as possible to avoid disturbing electrical lines or pulling out excess insulation.
