Why Do Basements in Gerritsen Beach Take On Water?
The peninsula is low and surrounded by water, so groundwater sits close to the surface and rises after rain or high tides. Water finds its way through cracks, joints between wall and floor, window wells and porous block. A dry basement here needs a plan, not just a coat of paint.
Gerritsen Beach was heavily flooded during Hurricane Sandy in 2012, and it is one of the low lying coastal areas of Brooklyn near FEMA flood zones. No basement can be guaranteed against a storm surge. What waterproofing can do is deal with the ordinary problems: seepage, damp walls, groundwater and rain that runs toward the house.
Many houses in the neighborhood have shallow basements, crawl spaces or raised first floors. A crawl space collects moisture just as a basement does, and it often goes ignored until mold smells or soft floors show up.
What Waterproofing Methods Suit a Coastal Lot?
Interior drainage with a sump pump is the most common answer on a high water table lot. It collects water at the footing and pumps it out. Crack injection, wall coatings and exterior work can add protection depending on how the water enters.
An interior system runs a channel along the base of the wall, leads water to a sump pit and pushes it out through a pump. It works from inside the house, so it avoids digging up the yard on a small lot. Exterior membranes go on the outside of the wall and need excavation, which is hard on tight lots but sometimes worth it.
Grading and downspouts matter too. Roof water dumped next to the foundation ends up in the basement. Extending downspouts and correcting the slope of the ground are among the cheaper fixes, and we check them first.
How Do We Choose the Right Fix?
We find where the water comes from, then match the method to it. A single leaking crack needs sealing, water at the floor joint needs drainage, and rising groundwater needs a pump. Guessing wastes money, so we trace the source before we quote.
| Where the water shows | Likely fix |
|---|---|
| Leaking wall crack | Inject or seal the crack, then check the outside |
| Water at the floor and wall joint | Interior drainage channel to a sump |
| Damp block walls | Wall coating, with drainage where needed |
| Standing water after storms | Sump pump with a proper discharge line |
| Wet or musty crawl space | Drainage, sealing and better ground cover |
Sump pumps depend on power and on a good discharge path. We talk through what happens in a power outage and where the water should go once it leaves the pit, because a pump that empties next to the house only makes the loop shorter.
Water on the Basement Floor After Rain?
Tell us the address and where it shows up. We will check the walls, floor and yard on a free visit.
What About Flood Insurance and Storm Surge?
Waterproofing manages groundwater and seepage. It does not make a house flood proof, and it does not replace flood insurance. In a storm surge, water can enter through doors, vents and walls in ways drainage cannot stop. Owners should talk to their insurer about coverage.
We are careful not to promise more than the work can do. What we can promise is a clear scope: what we will install, what it should handle and what it will not. That scope is in the written estimate.
We do not say any specific address is or is not in a flood zone. To check your property, use the city's flood maps or ask your insurer, and confirm current rules with the city if you plan major changes.
Can a Crawl Space Be Waterproofed Too?
Yes. A crawl space is treated like a small basement: we look for where water enters, add drainage or a pump if needed, seal cracks and cover bare ground. Keeping it dry protects the floor above and cuts down on musty smells.
Crawl spaces are common in the neighborhood, and most owners do not look under the house until a floor feels soft. Water that stands there for weeks feeds mold and can rot wood framing.
We can inspect the space, show you photos of what we find and recommend the least invasive fix. Access is often tight, which affects how long the work takes.
Are Permits Needed for Waterproofing Work?
Interior drainage and sealing often need no sidewalk permit, but plumbing connections, structural repairs and excavation can involve city filings. A sump discharge also has to go somewhere allowed. Confirm current requirements with the city, and we will point out where they may apply.
We explain each of these at the visit so nothing surprises you after work begins. If the job touches the public sidewalk, we file the DOT permit for our work.

Crack sealing can be finished in a day. An interior drainage and sump system usually takes a few days on site, depending on the size of the basement. Exterior work takes longer because of excavation. We give a schedule with the written price.

FAQ
Gerritsen Beach Waterproofing Questions
We cannot promise that on a low coastal lot. We can manage groundwater and seepage with drainage and a sump, and we explain what a system will and will not handle.
Often yes on a high water table lot. If water only enters at one crack, sealing may be enough. We decide after we see where the water comes from.
Crawl spaces hold moisture and can cause odors and rot. We look at drainage, sealing and ground cover to keep them dry.
No. Waterproofing handles groundwater and seepage. A storm surge is a different problem, and flood insurance is the tool for that risk.
Yes. We inspect the space and give a written price at no cost. Call (718) 468-8803 to book a visit.
Extend downspouts away from the wall, keep the ground sloped away from the foundation and keep window wells clear. Those simple steps help every basement.
