Step 1: Use Protection
Every project is different, but step one should be protecting the surfaces that are finished.
It is often a balancing act utilizing the right amount of surface protection, without interfering with work progress or the continuing use of the space for the homeowner.
In this example kitchen where removal of the damaged drywall was necessary, we hung plastic over the cupboards to control dust, and used ram board on the new counter surfaces and floor. In other situations, drop cloths or carpet runners make more sense. Also, some protection may have a risk of damaging the surface they are intended to protect, such as masking tape pulling paint/plaster off of surfaces or discoloring stained wood.
When we are doing our free estimates, we are noting what surfaces need protection from the likely entry point to the work space.
Does the installer you are considering include this? Maybe its worth asking.
