Homeowner Guidance
Contractor Standards
Before hiring a contractor for drainage work, homeowners should confirm applicable licensing, insurance, written scope, pricing, permits and excavation requirements.
Applicable Suffolk County licensing
Confirm the contractor holds the applicable Suffolk County home-improvement contractor license for the work being offered.
Current insurance coverage
Ask the contractor to confirm current insurance coverage before authorizing any work.
New York 811 safe-digging responsibility
For excavation and trenching, the contractor or excavator is responsible for the New York 811 locate request and must follow the required waiting and marking process before mechanized digging begins.
Project-specific permit review
Drainage work can involve grading, site work, dewatering, road-opening, wetland, or other requirements depending on the property and scope. Ask the contractor to identify and address requirements that apply to the proposed work.
Clear scope and homeowner approval
Homeowners should receive a written scope and pricing from the contractor and review the contractor's credentials, insurance, terms, and proposed drainage plan before authorizing work.
