Compare contractor estimates by aligning the scope, materials, allowances, exclusions, permit responsibility, payment schedule, warranty and timing. If proposals describe different projects, their bottom-line prices cannot be compared fairly.
Key takeaways
- Normalize the scope first
- List every allowance and exclusion
- Compare payment milestones
- Resolve ambiguous language in writing
Create a side-by-side scope
List each major task and mark whether it is included, excluded or unclear in every proposal. This exposes differences hidden inside a single total.
Review financial assumptions
Compare allowances, unit prices, deposits, progress payments, retainage if applicable and the method for pricing changes. A low allowance can make an estimate appear artificially attractive.
Compare accountability and execution
Identify who supervises, who obtains permits, the expected schedule, communication process, cleanup obligations and warranty response. These factors materially affect the homeowner experience.
Frequently asked questions
Why can contractor estimates differ so much?
They may reflect different scopes, materials, assumptions, supervision, insurance, overhead, scheduling or levels of completeness.
What should I do with an unclear estimate?
Ask for written clarification or a revised proposal before making a selection or paying a deposit.
