Wet basements in Ardsley
Ardsley is a village in the Town of Greenburgh crossed by the Saw Mill River and Sprain Brook. The Saw Mill flooded downtown Ardsley during Hurricane Agnes in 1972 and again in 1980, 1984 and September 1999, and the Army Corps of Engineers has since completed flood control projects there.
Homes near the river and the brook face the most groundwater. Up the hills, wet basements are more often a matter of runoff, grading and old foundation joints.
A contractor who serves Ardsley will contact you, inspect the basement and the outside of the house, and give you a written proposal. Look for one that names where the water gets in and why, then recommends a fix that matches: sealing a crack, extending downspouts and regrading, adding a sump pump, or installing an interior drain.
Before the visit, note which walls get wet, how soon after rain it starts and if you have a sump pump. Check that gutters are clear and downspouts discharge away from the house. Those two steps alone fix some basements and help the contractor see what is left.
Ask any contractor working in Ardsley for their Westchester County home improvement license number, proof of insurance, the warranty in writing and where any pumped water will be discharged. If the walls show long horizontal cracks or bowing, ask for foundation crack repair advice and consider a structural engineer before any waterproofing goes in.

What is the most common cause of basement leaks?
Water pressing against the foundation after heavy rain, made worse by downspouts and grading that put roof water right at the wall. The joint between the floor and the wall is the most common entry point.
