A contractor checklist you can use during every estimate. Here’s a straightforward place to start, with the questions and details worth checking before you make a decision.
Ask for the exact product
A quote should identify manufacturer, window model, frame type, glass package, relevant efficiency ratings, and any hardware or finish upgrades. Make sure you are comparing equivalent features.
Clarify installation and surprises
Ask whether the job is insert or full-frame replacement. Confirm how hidden rot, damaged trim, drywall, stucco, or other repairs are priced if discovered. Discuss required permits and inspections.
Verify the business
Check relevant licensing, insurance, references, recent work, and complaint history using official sources available in your state. Request a written schedule and scope before providing a deposit.
Understand the payment terms
Review deposit requirements, milestones, financing terms, warranty coverage, and cancellation rights under applicable law. Be especially careful with urgent, today-only pressure.
Use the same written checklist with at least two or three contractors.
