Questions to ask before you sign
- What is in the price? A written quote split into labour, materials, equipment and permits.
- Who pulls the permit, and how long is approval taking?
- What warranty comes from you, and what from the manufacturer?
- What is your license number? Then check it yourself.
Red flags: a large deposit before any permit, no written contract, a license that doesn't match the company name.
