Do I need a hazardous materials survey before refurbishment or demolition?

Yes, absolutely. Before any refurbishment or demolition work, a hazardous materials survey is normally required to keep workers and the environment safe. These activities are far more disruptive than normal building use, meaning any hidden hazardous materials are much more likely to be disturbed.

Contractors will also expect this information upfront. Without it, they may refuse to begin work or insist on delays until a survey is completed. Not having one can create real safety risks and even legal problems, especially in commercial settings.
