Mold Inspection in Elmont, NY, Using When the Damp Appears

An independent assessor uses when your Elmont damp appears and disappears to tell a leak or condensation from the ground, and writes down the source and the scope.

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.

Local Context

How an Elmont assessor uses the pattern of the damp

An Elmont assessment turns your observations into a finding: the assessor measures the growth and the wet material, matches when the damp shows against how each possible source behaves, and writes the source and the repair trade into a plan. Groundwater has a signature here, and it is stillness. USGS well N 9979 in Elmont read the water table 35.96 feet down in March, 35.80 in April and 36.10 in June 2016, a spread of about a third of a foot over a season.

What mold inspection involves in Elmont

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.
Deciding

Keeping a damp diary before the Elmont visit

Before you book, spend a week or two noting when the damp is worse and when it eases. A patch that darkens after rain and fades in dry weather is surface water or a gutter. One that shows up on muggy days on cold walls and pipes is condensation, and the EPA's ceiling for indoor humidity is 60 percent. One that never changes may be a steady leak. None of those behaves like a table that moved a few inches in three months. If the patch is small and the cause is obvious, you may be able to deal with it yourself.

  1. Dates and weather

    Jot down the date, whether it rained and how the spot looked. Two weeks of notes beat a single visit.

  2. A humidity reading

    An inexpensive meter from a hardware store tells you whether the air is above 60 percent.

  3. Which walls

    Damp on an outside wall after rain points outside; damp near a bathroom points at plumbing.

Elmont's water table, three readings in one spring

USGS well N 9979, inside Elmont, measured the water table 35.96 feet down on March 17, 35.80 feet on April 18 and 36.10 feet on June 6, 2016.

EPA recommends keeping indoor relative humidity below 60 percent, ideally between 30 and 50 percent, and notes that it can be checked with an inexpensive moisture or humidity meter sold at hardware stores.

New York Labor Law section 945 requires the mold assessment licensee to prepare a written remediation plan before work starts, covering the work areas, quantities of material, methods, protective equipment, clearance procedures and criteria, occupant notices, an estimate of cost and time and, where possible, the underlying sources of moisture with the type of contractor who should fix them.

Questions

What Elmont owners ask before the assessor reads their notes

Does waterproofing help if the damp comes and goes?

Rarely. Waterproofing is aimed at water pressing in from the ground, and the Elmont well shows groundwater sitting about 36 feet down and barely moving. Damp that comes and goes is a surface, leak or air problem, each with a cheaper fix.

Will the assessor want my notes?

They are the most useful thing you can hand over. They let the assessor test the likeliest source first instead of opening walls to find it.
