The answer to 'how often to clean post-construction cleaning' is that it should be done as soon as possible after the construction or renovation project is completed. Post-construction cleaning is essential to remove all the dust, debris, and residue left behind from the construction work. This cleaning should be done before the homeowners move in or start using the space.
Typically, post-construction cleaning should be done within 1-2 weeks of the project's completion. The longer you wait, the more difficult the cleaning will be. Dust and debris can settle into crevices and become harder to remove over time. It's best to schedule the post-construction cleaning as soon as the construction crew is finished with their work.
