Why Westchester basements get wet
Many Westchester homes sit on sloped lots, ledge and clay-rich or saturated soils, and a lot of the housing stock predates modern waterproofing, with older stone, brick or early block foundations. Heavy storms, high water tables near the Sound and rivers, and gutters or grading that send water toward the house all add up. Our advice: fix the water source first, starting with gutters, downspouts and grading, then price drainage and a pump with backup power.
Check the license before you sign
Westchester County requires home improvement contractors, including waterproofing contractors, to hold a county license, and the county publishes a search. Every home improvement company listed here was looked up in that search, and each profile says when. Mold firms are checked in the state's mold-license data instead. Mold assessors and remediators are licensed separately by the state. How to check a license or open the county search.
