Why Do Hillside Basements in Fordham Heights Get Wet?
Runoff from the slope above is the main reason. Fordham Heights is on higher ground that falls steeply toward the Harlem River, and rain moves downhill fast, pressing against uphill walls and pooling at the base of downhill ones. Old foundation walls give water many ways in.
The residential blocks are on high ground, and the area has no particular flood exposure beyond heavy rain sewer backups. So the water that reaches a basement here comes from surface runoff, groundwater in the hill and aging drains rather than from flooding.
- Seepage through the uphill wall
- Water at the floor and wall joint
- Damp, white deposits on masonry
- Peeling paint and a musty smell
- Floor drain that backs up in storms
- Moisture behind a retaining wall
Pre war apartment buildings and walk ups here have stone or brick basements with mortar that has weakened. Walls cut into the slope sit against soil, and soil holds water.
Buildings on the steepest lots often have a rear or side wall that is fully below grade, and those are the walls to watch.

How We Fix It
How Is a Wet Basement Fixed on a Slope?
The fix follows the source. Cracks and joints are sealed, surface water is redirected with grading and gutters, and groundwater is collected with an interior drain and, where needed, a sump pump. On hillsides, intercepting water above the wall often helps most. Sewer backups go to a licensed plumber.
Old masonry needs repair before any coating. Sealers over damp, crumbling mortar peel off, so the wall is repointed or patched first and the finish goes on last.
We look at the whole slope. Downspouts, retaining walls, paved areas and neighbors' runoff all affect how much water reaches your wall. A plan that handles only the wall misses half the problem.
In occupied buildings, we protect finished areas, control dust and clean up each day.
What Rules and Limits Apply to Waterproofing in Fordham Heights?
Sealing and interior drains often need no special filing, but structural repairs and retaining walls can need an engineer and DOB permits. Digging at the sidewalk generally needs a DOT permit. No historic district is confirmed here. Confirm current rules with the city.
If water rises through the floor drain in storms, that is a sewer backup. A licensed plumber handles it, and a backwater valve can help keep the sewer from pushing water into the building.
A sump discharge needs a safe outlet. We plan it so it does not flood the sidewalk or a neighbor, and the plan is in the estimate. See our sidewalk violations guide for sidewalk rules that may apply.
Will waterproofing make the basement bone dry?
It reduces and controls water, but we do not promise a perfectly dry space. Humidity may remain in old cellars, and a dehumidifier can help.
