Excess materials are common byproducts of renovation projects, but with strategic handling, these leftovers need not go to waste. Stockpiling surplus tiles, paint, or lumber for future repairs or small projects ensures you have matching materials on hand, reducing the need to buy more later. For inherently excessive materials, consider donating usable items to community organizations, schools, or nonprofit building centers. Proactive coordination with suppliers to return full, unopened packages also trims waste and recoups some costs, contributing further to responsible resource management.
