Yonkers
Yonkers basement waterproofing questions often come down to steep hillside lots, shallow bedrock and the flash flooding that hit Westchester during Ida. Typical work here includes interior drainage on rock-bound foundations, sump pumps, exterior regrading and window-well drainage.
Ground and groundwater in Yonkers
Yonkers climbs from the Hudson River up steep ridges with shallow bedrock, so water running downhill and perched on rock often ends up against foundation walls.
The Saw Mill River, partly daylighted in downtown Yonkers, and steep streets carry fast runoff during cloudbursts.
Climate, freeze–thaw and flood history
The remnants of Hurricane Ida in September 2021 flooded basements across southern Westchester.
Water that reaches a foundation wall finds cracks, cold joints and the joint between wall and floor first, so the right fix depends on where the water is coming in and how high the groundwater rises.
Local authorities and codes
City of Yonkers Department of Housing and Buildings handles permits; Westchester County publishes flood and stormwater resources.
In New York State, basement and foundation work falls under the Uniform Fire Prevention and Building Code administered locally; New York City applies its own NYC Construction Codes through the Department of Buildings.

Check the official flood map for your address, keep gutters and downspouts clear and pointed away from the house, and photograph any water, damp patches or cracks before the visit.
