The answer to 'my post-construction cleaning is filthy' is that post-construction cleaning can be extremely challenging due to the extensive debris, dust, and grime left behind from the construction process. Common causes include drywall dust, sawdust, adhesive residue, and caked-on dirt and mud. Symptoms include surfaces that feel gritty, floors that are difficult to clean, and a general sense of dirtiness throughout the home.
In many cases, a thorough professional post-construction cleaning is recommended to fully restore the home to a livable condition. Homeowners may be able to handle some light cleaning themselves, but deep cleaning of every nook and cranny is best left to experienced professionals with the right tools and expertise.
