Mold Removal in Hastings-on-Hudson, Where the Water Comes Up
Water rising through a Hastings slab and water arriving off the roof look the same on the wall and are fixed by completely different work, so the diagnosis is worth getting right before the money goes out. Hastings-on-Hudson is the one village on this site whose residents named groundwater and runoff flooding as its own category, at Nepperhan Avenue and North End Place, alongside the creek that floods the street around Branford Road, Fenwick Road and Ravensdale Avenue.

Damp slab, sound roof, no plumbing fault?
That combination points at groundwater and it is fixed differently. Tell us where it appears and what the weather was doing.
Groundwater, gutters and which office signs off in Hastings
Groundwater pushing up through a slab is not a gutter problem and no amount of work on the roofline will touch it, which is why the first job in this village is telling the two apart. The village expects the problem to grow: it named aging stormwater conveyance and climate change as reasons to expect more flooding, reported that some homes flood regularly, and noted that its own public works facility sits in the special flood hazard area and floods in large storms. So a sump or a perimeter drain specified here should be sized for worse than the last ten years. The recorded loss is real but contained, 40 paid claims against 29 policies in force with 4 repetitive loss properties, and 63 claim records in the 10706 ZIP code, 7 of them from the first days of September 2021, which is why the question is about your specific address rather than about the village. Getting that history is the awkward part. Hastings uses a commercial flood risk website to identify flood prone homes but keeps no list of private properties actually damaged, so a risk score is not a history and the owner's county disclosure form is. On permissions, an address inside the village is in the Town of Greenburgh for tax purposes but gets its building permit from village hall, and Hastings is one of only two municipalities here whose Building Inspector holds the floodplain manager credential, so an early conversation with that office is unusually worth having. Two practical constraints on the work: 2,916 of the village's 3,272 homes were built in 1969 or earlier and 2,524 of 3,164 occupied homes are owner occupied, so lead safe practice is the norm and the decision sits with the household, and no licensed mold firm of either kind is based in the village, so both halves of a lawful job are coordinated from outside it.
