Typical lead time is same day to a week; longer in peak season. 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?

Delaware Rules

Delaware requires contractors to register with the state. Threshold: No project-dollar floor for the contractor business license. Read the Delaware license summary.

  • A proper load calculation matters more than matching the old unit’s size.
  • Compare the same size and efficiency across quotes.
