Local Conditions
Why Do Alphabet City Cellars Get Wet?
The eastern part of the neighborhood sits low, close to the East River. Groundwater rises after heavy rain, and the area near Avenue C and Avenue D flooded in Hurricane Sandy. Old stone and brick cellar walls let that water in through cracks, joints and floor edges.
Cellar doors and basement stair openings on tenement blocks add more paths. Water runs down the stairwell, collects at the door and seeps under the sill. A clogged stair drain turns the stairwell into a bathtub.
Wet cellars are not only a problem in storm years. Many Alphabet City basements hold shops, storage or tenant space. Moisture there brings mold, rotting wood and ruined stock. The city is raising East River Park for flood protection, but that does not fix a leak in your wall today.
Not every wet cellar has the same source. Surface water, groundwater, a leaking pipe and a sewer backup each need a different fix.
How Is a Wet Basement Waterproofed?
We start by finding where the water comes from. Fixes include sealing cracks, repointing walls, parging, interior drains that lead water to a sump, and exterior work that keeps water off the wall. The right mix depends on the building and the source.
Outside, we repair sidewalk and areaway concrete so water pitches away from the building. Inside, we seal walls and set drain channels along the floor edge. A sump pump moves collected water out.
If water comes up through floor drains or toilets, the cause may be the sewer. A sewer backup is plumbing work, so a licensed plumber is involved and a backwater valve is often part of the answer. We work with your plumber when that is the cause.
Permits and approvals
Sidewalk and areaway work on the public walk generally needs a DOT permit. Structural changes can involve the Department of Buildings. The East 10th Street Historic District faces Tompkins Square Park, so landmark review may apply to exterior work there. Confirm current rules with the city.
If foundation walls are cracking or moving, an engineer may need to look at them. We promise no outcomes, and we tell you plainly what we find.
Cost Factors
What Affects the Cost of Waterproofing Here?
Source of the water
A cellar door leak is a smaller job than groundwater pushing through the full wall.
Size of the cellar
More wall and floor to treat means more labor and material.
Interior or exterior method
Exterior digging in a tight tenement lot is harder than interior drainage work.
Pump and drainage
Low ground may call for a sump pump and a reliable discharge path.
