Before You Hire

Typical lead time is several weeks, due to custom order lead times. Ask:

  • What is your license number, and which state or city issued it?
  • Can you send a current certificate of liability insurance and proof of workers’ compensation?
  • Will the contract list the scope, materials, price, start and finish dates and payment schedule?
  • Who pulls the permits, and are they included in the price?
  • Who will run the job day to day, and will you use subcontractors?
