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.

Deciding

Massapequa owners: permit office, source and what went back

With 97.0 percent of Massapequa homes standing as detached houses and 3.2 percent rented, the job almost always belongs to the owner. Check the government first: the hamlet of Massapequa files with the Town of Oyster Bay, while Massapequa Park is a separate village with its own building department. Then confirm the plan's source repair is done, whether that is a plumber or a drainage trade. Removing growth while low-ground water is still reaching the floor means removing it twice.

  1. Town or village

    Massapequa hamlet goes to the Town of Oyster Bay; Massapequa Park has its own village hall.

  2. What was rebuilt

    Tell the firms which walls and floors went back after a flood. Those are the ones the plan may open.

  3. Drainage done first

    If the plan names a drainage contractor, that work comes before containment.

The New York State Department of Labor lists among a mold assessor's main duties identifying, when possible, the underlying source of moisture causing the growth, and says the remediation plan should state that source and how to remedy it, adding that the water source should always be corrected before cleanup or the mold will likely grow back.

New York Labor Law section 936 bars any licensee from performing both the mold assessment and the mold remediation on the same property, bars any person from owning an interest in both licensees on that property, and requires the assessment licensee to give a written report to each client it assesses for pay.

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.

What mold remediation involves in Massapequa

Local Context

Removing mold from a Massapequa house that has been rebuilt

A Massapequa remediation follows the plan: containment, removal of the drywall, insulation, flooring and pad with growth, cleaning of framing and concrete that can stay, and a room left ready for independent clearance. Some of the material coming out here was itself a repair. Across the whole Town of Oyster Bay, 60 properties were substantially damaged in recent floods, the town reports, and a house rebuilt after water can carry new finishes over framing that was never fully dried.

Questions

Massapequa questions about removal after an earlier flood

We rebuilt after a flood. Why is there mold now?

Often because something was closed up before it was dry, or because water is still reaching the same spot. The assessment tells you which, and the removal follows from it.

Can the removal firm install a sump while it is there?

Not as part of the mold work. The plan names the drainage trade separately, and New York keeps the scope with an independent assessor, not with the firm doing the removal.
