We'll walk you through the biggest threats, help you assess your home, and equip you with actionable solutions that can save you time, money, and stress.

Understanding the Risks

Types of Flooding Common in Brooklyn

Brooklyn experiences several types of flooding, including:

• Coastal flooding from storm surges and rising tides.

• Urban flooding due to overwhelmed sewer systems.

• Basement flooding from poor drainage or foundation cracks.

Certain neighborhoods—like Red Hook, Gowanus, and Canarsie—are especially vulnerable due to their proximity to water bodies and outdated drainage infrastructure.

Impact of Flooding on Homes and Businesses

Flood damage can compromise structural integrity, ruin interiors, and create long-term health risks like mold growth. Businesses may face property loss, inventory damage, and operational downtime. Homeowners are often left with repair bills running into tens of thousands of dollars.

Assessing Your Property

Identifying Vulnerable Areas in Your Home

Start by checking common entry points for water:

• Basement floors and walls

• Ground-level windows and doors

• Crawlspaces and foundation cracks

Look for signs of past flooding like water stains, musty odors, or rust around pipes.

Conducting a Professional Waterproofing Assessment

Hire a licensed waterproofing expert to perform a full inspection. They’ll use thermal imaging, moisture meters, and visual checks to assess risk areas and recommend targeted solutions.

Essential Waterproofing Tips

Sealing Windows and Doors

Use weatherproof caulk or silicone sealant around window and door frames. Install window well covers and door sweeps to keep water from seeping in.

Installing Sump Pumps and Proper Drainage Systems

A sump pump helps divert water away from your basement during heavy rains. Combine it with:

• A battery backup system

• Interior and exterior French drains

• Downspout extensions

These systems work together to direct water away from your foundation.

Waterproofing Materials and Techniques

Selecting Appropriate Waterproofing Materials

Depending on the severity of risk, you may need:

• Waterproof paints and coatings for interior basement walls

• Concrete sealers for floors and foundations

• Sheet membranes or vapor barriers

Applying Waterproof Coatings and Sealants

Apply coatings in dry conditions for best results. Follow manufacturer instructions and allow ample curing time. For foundation walls, consider a two-layer system: one for adhesion and another for water resistance.

This is where professional Waterproofing Services in Brooklyn come into play, especially when dealing with complex or large-scale applications.

Emergency Preparedness

Creating an Emergency Plan

Every household should have a flood emergency plan. This includes:

• Knowing your evacuation routes

• Listing emergency contacts

• Protecting important documents in waterproof containers

Assembling an Emergency Waterproofing Kit

Be ready to act fast. Your kit should include:

• Sandbags or water-activated barriers

• Plastic sheeting and duct tape

• Portable sump pump

• Flashlights and batteries

• First aid supplies

Long-term Solutions for Reducing Flood Risk

Elevating Vulnerable Structures

Raise electrical systems, HVAC units, and major appliances above potential flood levels. For severe cases, consider elevating your entire home structure on piers or stilts.

Landscaping Strategies to Improve Drainage

Smart landscaping can divert water away from your home:

• Install swales or berms

• Use permeable pavers

• Maintain clean gutters and downspouts

Native plants and rain gardens also help absorb excess rainwater.

• NYC’s FloodHelpNY risk assessment tool
