Six short questions about the water and the house, then your details. Under a minute.

Question 1What brought you here?
Question 2Where does the house sit?

In Westchester this is the question that most often decides what kind of job it is. A house on the Hudson or the Sound can take tidal or surge water, a house in a stream valley takes river water, and a house on higher ground mostly takes groundwater or runoff. The county's own hazard plan puts only about one building in forty inside the mapped flood area, so most wet basements here are outside it.

Question 3Where did the water come from?

Clean water from a supply pipe, rainwater through a wall, and water that rose out of a river, the Sound or a drain are graded differently by the water damage trade's own standard, and the grade decides whether soaked materials can be dried or have to be cut out. Guessing wrong in either direction costs money, so an honest not sure is better than a confident guess.

Question 4How long has it been wet?

Federal guidance says material dried within 24 to 48 hours of a leak will in most cases not grow mold. Past that window the question moves from drying to finding out what has already grown, which is why this changes who we send first.

Question 5What was in the space that got wet?

What has to be removed depends on the materials as much as on the water. Carpet, pad, drywall and insulation that soaked up contaminated water usually come out. Concrete, block and framing are usually cleaned and dried where they are.

Question 6Why look into it now?

This decides what order things happen in. A closing date or a health worry moves the assessment to the front of the queue.

Tarrytown's backflow warning and its waterfront acres

A quiet tree-lined Westchester street of colonial and Tudor houses

Tarrytown's annex lists as a vulnerability that "With the rise of sea levels/storm surge/storm rainwater increasing, culverts and sewers may require protection to prevent damaging backflow", and records an April 13, 2020 wind storm with trees down and sewer back up.

The Village of Tarrytown told the county that "Nearly 60 acres of land along the north-west portion of the Hudson River is prone to flooding", that the Loh Park area was improved by 2019 to reduce flooding to the 100-year storm event through stormwater detention and rerouted and upsized culverts, and that it keeps a list of flood-damaged properties in the Building Department for Loh Park.

Local Context

What the assessor records in a Tarrytown basement

The report gives you three things you cannot get from looking: where the moisture actually reaches, what it is growing on, and what kind of water put it there. That third item decides the scope, because a waste line backflow from beyond a trap is graded as the trade's most contaminated water regardless of how clean it looks, while a supply line leak is not. The Village itself flags backflow as a vulnerability, noting that rising seas and heavier storm rain may push damaging backflow through its culverts and sewers.

Deciding

Buying or owning in Tarrytown: when to book

Owners should book when water came up through a drain, when it reached finished space, or when growth has returned after cleaning. Buyers looking at a house in the low areas near the river have a reason of their own: the Village says nearly 60 acres along the north-west Hudson shore are prone to flooding, and its Building Department at 1 Depot Plaza keeps a list of flood damaged properties for the Loh Park area. Ask about that list first. If the only issue is a musty closet on an outside wall, a dehumidifier may settle it.

  1. Drain or pipe

    Tell the assessor exactly where water first appeared. Up through a floor drain points one way; down from a ceiling points another.

  2. Ask the Village first

    For a Loh Park address, the Building Department's list of flood damaged properties costs nothing to ask about.

  3. Old paint in the removal area

    Three quarters of Tarrytown homes predate 1980. Ask whether the plan's removal areas include painted surfaces, which in a pre-1978 house bring lead-safe rules.

Questions

Tarrytown questions about inspecting for backflow

The water from the drain looked clear. Is it still backflow?

It can be. The standard grades waste line backflow from beyond a trap as its most contaminated class regardless of visible content or color. The assessor looks at where the water came from, not just how it looks.

Can a buyer book an assessment before closing?

Yes, with the seller's permission to enter. The report is written for whoever pays for it, and it describes the condition on the day of the visit.

Next Step

Owner or buyer, tell us what you have seen. A person reads it and says whether an assessment is worth it.
