How to Compare Contractor Quotes
The lowest number is rarely the whole story. Compare quotes line by line so you know what is included.

Compare contractor quotes by scope first and price second. Two quotes only compare cleanly when they cover the same work, materials, and conditions. Otherwise you are comparing different projects.
Step by step
- Give every contractor the same written scope.
- Compare line items, not just totals.
- Check allowances, which are placeholder amounts that can rise later.
- Look for exclusions such as patching, painting, or cleanup.
- Verify licensing and insurance where required.
- Compare timelines, since a cheaper bid that takes much longer may not be better value.
- Ask clarifying questions and get answers in writing.
What to compare, side by side
- Scope of work and quantity
- Materials and product specifications
- Allowances and who chooses the products
- Exclusions and assumptions
- Permits, disposal, and cleanup
- Timeline and start date
- Payment schedule and change order terms
- Warranty on labor and materials
Estimating quantities helps you spot a quote that is too thin. Run the flooring calculator or paint calculator.
The cheapest bid has a cost too
Bids far below the others often omit scope, use lower-grade materials, or rely on change orders to recover the difference later. Ask why before you celebrate a low number.

Frequently asked questions
- How many quotes should I get?
- At least three itemized quotes is a common approach. It gives you a sense of the going range and reveals when one bid is unusually low or missing scope.
- Should I choose the lowest quote?
- Not automatically. A low bid may exclude work, use lower-grade materials, or rely on allowances that increase later. Compare scope, materials, timeline, and references.
- How do I check a contractor?
- Ask for references and proof of licensing and insurance where required, then verify those details with the relevant local authority or insurer.
