Waterproofing Contractors in Brooklyn
Basement, foundation, roof and facade waterproofing that stops leaks at the source and keeps your property dry. Grace General Construction Corp has provided waterproofing in Brooklyn since 2008 as a licensed, bonded and insured contractor based in the Bronx.
Brooklyn row houses typically have flat roofs shared along the block, so a neighbor’s roof edge and the parapet between buildings matter. Low-lying areas near Gowanus, Red Hook, Canarsie and Sheepshead Bay see more groundwater and flood-related basement problems.
Our waterproofing services in Brooklyn include:
- Crack injection
- Interior drainage and sump systems
- Facade and parapet waterproofing
- Roof coatings
- Breathable masonry coatings
- Basement and foundation waterproofing
Signs you need waterproofing
Call us for a free inspection in Brooklyn if you notice any of these:
- Water at the floor-wall joint
- Efflorescence on foundation walls
- Peeling paint on exterior walls
- Leaks during heavy rain
- Damp or musty basement
Catching problems early usually means a smaller repair instead of a bigger rebuild.
How we work in Brooklyn
Many Brooklyn blocks are in historic districts — exterior work there may need Landmarks Preservation Commission approval before DOB permits. We flag it at the first visit and plan the schedule around it.

The work, then a walkthrough
Our crew completes the job, cleans up, and walks it with you before we call it done.
Shared roofs and garden-level water in Brooklyn
Brooklyn row houses share flat roofs and parapet walls along the block, so a neighbor’s failing roof edge can show up as a leak in your top floor. Garden apartments and cellars in low-lying areas like Gowanus, Red Hook, Canarsie and Sheepshead Bay see more groundwater, so we pair roof work with drainage and waterproofing below grade when needed.

We provide waterproofing throughout Brooklyn, including Park Slope, Bed-Stuy, Crown Heights, Flatbush, Bay Ridge, Bensonhurst, Sunset Park, Williamsburg, Greenpoint, Clinton Hill, Fort Greene, Prospect Heights, Canarsie, Sheepshead Bay, Dyker Heights and Carroll Gardens.

What clients say about our waterproofing work
Our results speak loud — but our clients speak louder. Rated 4.9 out of 5 from 66 reviews on Google.
We hired Grace General Construction Corp for a roofing job after dealing with leaks for a while, and I’m really glad we chose them. From the start, they were easy to work with and explained everything in a way that made sense.
The crew showed up on time, worked efficiently, and kept the area clean. The new roof looks great, and we haven’t had any issues since. Overall, a smooth experience and fair pricing.
I’d definitely recommend them to anyone looking for a reliable contractor in the Bronx.
We had a persistent leak that several contractors tried to patch, but the problem kept coming back. It was frustrating and costly. Grace General Construction Corp carefully inspected the issue and performed a proper roof repair instead of just a quick fix. They explained the problem clearly and fixed it the right way. Since then, no more leaks, even during heavy rain. Very satisfied with their honest and professional service.
We own a property with a flat roof, and pooling water was becoming a serious issue. It was starting to cause interior moisture problems. Grace General Construction Corp assessed the drainage issue and installed a proper flat roof solution to prevent standing water. The difference is incredible, no more ponding, no more stress. Their expertise and fair pricing made the whole process smooth. Highly satisfied with their roofing services.

Can you waterproof my basement from inside?
Many leaks can be stopped from inside with crack injection and drainage; some need exterior excavation. We tell you which.
Do you work on landmarked buildings in Brooklyn?
Yes. We match historic materials and details, and we flag Landmarks Preservation Commission requirements early so approvals are in place before exterior work begins.
Why does my Brooklyn basement leak only in heavy rain?
Usually from saturated soil, poor grading, failed drains or open cracks. We trace the water path before quoting.
Do you waterproof walls above ground?
Yes — facade, parapet and roof waterproofing are part of what we do.
Do you serve all of Brooklyn?
Yes — we work across Brooklyn, including Park Slope, Bed-Stuy, Crown Heights, Flatbush, Bay Ridge, Bensonhurst and every other neighborhood in the borough.
