What is the first thing you need to do in post-construction cleaning?

The first thing you need to do in post-construction cleaning is to remove debris. This includes removing any construction materials such as lumber, drywall, and insulation that may be present. Removing debris is an important step in the post-construction cleaning process as it allows you to have a clear view of the surfaces that need to be cleaned and it eliminates potential hazards such as sharp edges, exposed wiring and heavy equipment.
Removing debris can be done by hand or with the use of a debris removal service. It's important to have a clear plan on how to remove debris and where to dispose it properly. Once debris has been removed, you can then proceed with the cleaning of surfaces such as walls, floors, and ceilings, and the cleaning of windows, mirrors and other fixtures.
