Before you hire on Long Island
- Check the license number with the county that issued it. Nassau and Suffolk each license home improvement contractors separately.
- Ask for proof of insurance: general liability, plus workers' compensation if they have employees.
- Get a written contract with the price, payment schedule, start and finish dates, and the work described in detail.
- Confirm permits with your town or village building department before work starts.
