What Questions Should I Ask Before Signing a Window or Door Contract?

Before any contract is signed, get clear answers on:

• Who pulls the permit — you or the contractor? (A reputable pro handles this for you)
• What brands and materials do you recommend, and why? — a good installer explains trade-offs, not just upsells
• What is the project timeline, start to finish?
• Is cleanup and haul-away of old windows/doors included?
• What's the warranty — on both product and labor?
• What triggers extra charges, and how are those communicated before work begins?

A detailed written estimate prevents financial surprises later. Be wary of bids that are significantly lower than others — this often means lower-quality materials or corners being cut on installation. Payment schedules should be transparent: a deposit to order materials is reasonable, but never pay the full amount upfront.
