Crown Heights' Trusted Basement Waterproofing Specialists
If you’re searching for basement waterproofing in Crown Heights, you’ve probably already dealt with a damp basement wall, standing water after a storm, or a musty smell that keeps coming back. Bobby Contracts has spent more than 20 years fixing exactly this kind of water intrusion across Crown Heights’ varied building stock — from Renaissance Revival and Neo-Grec rowhouses to the grand freestanding mansions near Eastern Parkway and the pre-war apartment buildings throughout the neighborhood.
Our local waterproofing contractors understand how foundation type changes the right approach — a rowhouse basement with shared party walls needs a different plan than a standalone mansion foundation or a multi-unit apartment building’s cellar. We combine interior French drain systems, high-capacity sump pumps, and exterior membrane waterproofing to fix water problems at the source, whatever your building type.
Every Crown Heights basement waterproofing project starts with a full foundation inspection and a written, itemized plan, so you know exactly what’s being done, why, and what it costs before any work begins.

Crown Heights Basement Waterproofing FAQs
What causes basement water problems in Crown Heights?
Crown Heights’ housing stock spans century-old rowhouses, freestanding mansions, and pre-war apartment buildings, each with its own foundation type. As mortar joints age and settle, groundwater and surface runoff work their way in through cove joints, masonry pores, and foundation cracks — the most common cause of Crown Heights basement leaks.
How much does basement waterproofing cost in Crown Heights?
Cost depends on your basement’s square footage, the severity of water intrusion, your building type, and the system required — anything from a single crack injection to a full interior French drain with dual sump pumps. Bobby Contracts provides a written, itemized estimate after an on-site inspection of your Crown Heights property.
Is interior or exterior waterproofing better for Crown Heights buildings?
It depends on your property type. Attached rowhouses with no side-yard access typically do best with interior French drain systems and vapor barrier membranes. Freestanding mansions and homes with rear-yard or side access are often good candidates for exterior excavation and membrane waterproofing for longer-term protection.
How long does a basement waterproofing job take?
Most residential projects in Crown Heights wrap up in 2 to 4 business days, depending on basement access and whether the job requires concrete excavation or a new sump pump basin. Larger apartment buildings may take longer.
Do you work on residential and commercial properties?
Yes. We provide basement waterproofing services for homes, brownstones, apartment buildings, co-ops, condos, mixed-use properties, and commercial buildings throughout Brooklyn.
