Mold Removal in Mineola, NY, When Storm Runoff Reaches the House

When water shows up in a Mineola home after a storm, an assessment tells you whether it came across the ground outside or from somewhere inside, so the repair goes to the right place. NOAA's Mineola station averages 11.0 days a year with an inch of rain or more, and the Village reports that homes in its low-lying parts are prone to flooding from stormwater runoff.

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.

Planning

Runoff, a leak or the air: sorting a Mineola job

Mineola is an incorporated village with its own building department, and the county seat. A quarter of its housing, 25.3 percent, is in buildings of twenty or more units, and 32.0 percent of homes are rented, so check first whether the problem is yours to fix or the building's. For a house, runoff is the Mineola pattern to rule out. Water moving across the surface in a hard rain finds the low points of a house, such as a window well, a door at the foot of a driveway or a foundation wall set below the ground outside, and the fix for that is on the outside: grading, drainage or gutters. Groundwater rising under a Mineola home is the least likely source, and nothing should be sealed or pumped until the direction is known.

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.
