Ask what the allowance actually includes.
Two quotes can both say "tile allowance," but one may include only the tile material while the other includes setting materials, waste, delivery, tax, and contractor markup.
- Product: Which item, quality level, quantity, and vendor is the allowance based on?
- Labor: Is installation included elsewhere, included in the allowance, or excluded?
- Waste and delivery: Does the allowance include overage, shipping, freight, storage, or damage replacement?
- Markup and tax: Are contractor markup, sales tax, and procurement time included?
- Overages: What happens if the selected item costs more than the allowance?
