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.

The house, the water, and how to reach you

Who should we ask for?

How can we reach you?

Where is the property?

The contractor match is by property, not by person, so the street line matters.

Deciding

What to settle before a Tarrytown removal begins

Sewage is a professional job at any size: EPA advises calling in someone experienced with contaminated water rather than cleaning it yourself, even where a small patch of ordinary mold would be a homeowner task. Beyond that, compare the bid to the plan, ask whether the crew works lead-safe in a house built before 1978, and ask the Village Building Department at 1 Depot Plaza whether the rebuild needs a permit. A plumber, not the removal firm, deals with why the drain backed up.

  1. Not a do-it-yourself job

    Sewage changes the rule of thumb. Even a small area goes to a firm equipped for contaminated water.

  2. Plumber for the cause

    The removal firm takes out what the water reached. Why it backed up, and whether a backwater valve makes sense, is a plumber's question.

  3. Village permit

    Ask the Tarrytown Building Department about permits for the rebuild before walls go back.

Tarrytown's sewer back up record and the removal order

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 S500 text quoted in the consensus body's statement says that if the water is Category 1 the restorer can proceed without contamination controls, but "With regard to Category 2 or 3 water intrusions, remediation should occur prior to restorative drying and restorers shall use contamination controls and appropriate worker protection."

EPA advises that if the moldy area is less than about 10 square feet, "in most cases, you can handle the job yourself", but "If the water and/or mold damage was caused by sewage or other contaminated water, then call in a professional who has experience cleaning and fixing buildings damaged by contaminated water." It also warns: "Do not run the HVAC system if you know or suspect that it is contaminated with mold."

What mold remediation involves in Tarrytown

Local Context

Removing what sewer water reached in Tarrytown

After a backflow the job is removal first and drying second, done by a crew in protective gear. Everything porous the water touched, drywall, insulation, carpet, boxes on the floor, comes out and is bagged under containment; hard surfaces and framing are cleaned to the plan; and only then does drying begin. The standard's text is explicit that after contaminated water, remediation occurs before restorative drying, with contamination controls and worker protection. Tarrytown's hazard history records a 2020 wind storm that brought a sewer back up, so this is not only a flood scenario.

Questions

Tarrytown questions about sewage cleanup and removal

Can I keep things that were stored on the basement floor?

Hard items that can be washed and disinfected often can. Porous things that soaked up sewage, like cardboard, upholstery and rugs, are usually discarded. The plan and the firm will say which is which.

Should I run the heat or air conditioning while the basement is contaminated?

Not if the system may have drawn in contaminated air. EPA warns against running HVAC you suspect is contaminated with mold, so have it checked before turning it back on.
