Homeowner checklist

How to Compare Home-Service Estimates

A consistent way to compare diagnosis, included work, exclusions, permits, cleanup, warranties, and payment terms.

Why this checklist matters

Two totals are comparable only when the diagnosis, quantities, access, permits, cleanup, restoration, warranty, and exclusions are visible. Rebuild the comparison around scope, not price alone.

Checklist

written diagnosis and supporting tests
materials, model numbers, and quantities
labor, permits, disposal, and cleanup
access, patching, and restoration exclusions
warranty provider and claim process
deposit, milestones, and change-order terms

Questions before authorizing work

Do both estimates solve the same diagnosed problem?
Are models, materials, and quantities named?
Who owns access and finish restoration?
Are permits, cleanup, and disposal included?
What triggers a change order?

Build the written record

Keep the diagnosis, estimates, model numbers, permits, photographs, change orders, invoices, test results, warranty terms, and owner instructions together. Record which provider owns access, cleanup, and finish restoration.
