Tips for Hiring a Waterproofing Contractor in Nassau County
Understand the difference: interior French drains with a sump pump manage water that enters, while exterior waterproofing and foundation coating prevents entry. Ask which approach fits your situation and why.
Ask whether the system includes a sump pump with battery backup. Power outages during storms are when you need the pump most — a backup prevents flooding when the grid goes down.
Ask about lifetime warranties and whether they transfer to new owners. Get the warranty terms in writing and clarify what's covered — cracks, pump failure, and re-flooding.
