What Pros Include That You Don’t See
Professional bids bake in supervision, warranties, scheduling efficiency, and access to trade-only pricing. They own specialized tools, insurance, and relationships that reduce delay risk. A tile contractor, for example, arrives with leveling systems, wet saws, and dust control, delivering speed and consistency you might underestimate. When you see the line items for mobilization, protection, and cleanup, the premium often reflects real value. Understanding these inclusions lets you negotiate scope responsibly rather than chasing dangerously low, incomplete numbers.
