Mold Removal in Garden City, NY, a Village With Almost No Flood Record

In Garden City, an assessment usually settles the flood question quickly and points to the part of the house that is actually letting water in, which is where the money should go. The Village reports that it sits in an area of minimal flood hazard on FEMA's maps, and since 1978 flood insurance has paid just 6 claims totaling $4,849 across the whole village.

Tell us the town, the lowest level of the house and where the damp is showing. In Nassau that is usually enough to say whether the water is coming up from the ground or out of the house, and which licensed trade the job needs.

Six quick questions about the house and where the damp is showing, then your details. It takes about a minute.

Question 1What are you dealing with?
Question 2Which part of the county is the house in?

How far down the water sits under a Nassau house changes a great deal from the South Shore to the North Shore hills. Near the bays and harbors it can be close to the surface. Under much of the middle of the island and the hills it is far below the floor, so damp there usually comes from the house itself. The town is enough, and not sure is a fine answer.

Question 3What is the lowest level of the house?

A house built on a concrete slab, a house with a basement and a house over a crawl space get wet in different ways, and the fix is different for each. Many homes in this county were built on slabs with no basement at all.

Question 4Where is it showing up?

Where the damp appears is the first clue to which way the water came. Damp that starts low and spreads up points one way, and damp around a fixture, a window or a ceiling points another.

Question 5How long has this been going on?

Something that got wet in the last day or two can often still be dried. Something that has stayed damp for weeks usually cannot, and the job changes.

Question 6What would you like to happen next?

In New York the company that assesses mold and the company that removes it cannot be the same company on one job, so it helps to know where you want to start.

What a Garden City owner should check first

Garden City is an incorporated village with its own building department. Its houses are older than the county's, with 35.5 percent built in 1939 or earlier, and only 6.3 percent of homes are rented, so the owner is nearly always the one deciding. With the water table about 25 feet down at the USGS well in the village and almost no flood history, water in a Garden City lower level is coming from the house: an aging roof or gutter, a foundation crack, a slow plumbing leak, or damp air meeting a cold wall. The Village does note that its roads can flood in heavy rain because of drainage capacity, so if the water reached you during a storm, tell us. That is surface water arriving at the house, which is still a different job from groundwater.

A booking service, not the contractorWe arrange the job and a separately licensed New York firm carries it out, sets its own price and signs its own agreement with you.
The firm that assesses never removesState law keeps the company that writes the mold plan apart from the company that carries it out, and bars one owner from holding a stake in both on your property.
Every trade licensed and insuredEvery firm we book holds the New York license its part of the work calls for, and you can look any mold license up on the state's own open register.
