Basement water in Sleepy Hollow
Sleepy Hollow is a village in the Town of Mount Pleasant on the Hudson, at the mouth of the Pocantico River. Formerly North Tarrytown, it includes the Philipse Manor neighborhood and Sleepy Hollow Manor, where tree-lined streets have houses from the 1920s and 1930s. Part of the waterfront sits on fill where the Pocantico Bay once was.
Homes here range from older village houses on steep streets to the riverside development on the former plant site. Hillside houses see groundwater on uphill walls, and lower areas near the river and fill can have a high water table.

The contractor who follows up will look at the basement and walk the property, paying attention to slope, downspouts, window wells and any low spots. Then they give you a written proposal. In this part of Westchester, common fixes include French drains and curtain drains, sump pumps with battery backups and outside work like rerouting downspouts and regrading.
Help them help you: note which walls get wet and how soon after rain, take photos when it happens, and check that gutters are clear. If your house sits on a slope, mention it, along with any stone or block foundation. Walk the yard in a heavy rain if you can do it safely and watch where the water runs, because that is often the best clue to where it ends up.
Ask any contractor working in Sleepy Hollow for a Westchester County home improvement license number, proof of insurance, a written warranty and a clear plan for where drained water will go. Leave electrical work for pumps to licensed trades.

Questions homeowners ask
What does basement waterproofing cost in Sleepy Hollow?
This Old House puts interior waterproofing at about $3,000 on average and exterior work at roughly $7,000 or more. Slopes, rock and long walls raise the price, so get written estimates.
Who will inspect my basement in Sleepy Hollow?
A local waterproofing contractor who works in Sleepy Hollow and the surrounding area. They contact you and give you their own price.
Is a sump pump enough?
A pump only removes water that reaches the pit. Without a drain to collect water along the walls, or outside fixes to reduce the water, a pump alone may not keep the basement dry.
Should I start with gutters and grading?
Yes. Clearing gutters, extending downspouts and making sure soil slopes away cost little and can solve runoff problems on their own.
