Before you sign, ask to see completed work and speak to past clients. A good contractor is happy to show you.
Ask for a written quote that lists what is included and what is not. Check that it matches your drawings.
Agree the payment stages in writing. Payment should follow progress on site, not time.
Ask who will supervise the work day to day, how changes are handled and priced, and how long the project will take.
Make sure the contract states the start date, the completion date and what happens if either slips. Clear answers now prevent arguments later.
