Five quick questions, then your details. It takes about half a minute.

Question 1What are you dealing with?
Question 2Which part of the city is the property in?

This is the question that decides the job here. Jersey City runs from about 13 feet above sea level at the waterfront to about 148 feet on the Heights, roughly two miles apart, and the two ends fail in completely different ways. Down at the waterfront the water usually arrives up through a drain from a combined sewer, which is treated as contaminated, so soaked drywall and insulation come out rather than being dried. Up on the ridge it usually arrives sideways through a foundation wall, which is a drainage problem and not a contamination one. If you are not sure, pick the nearest.

Question 3Is anything still wet?

Wet material can start growing inside roughly a day to two days, so this one answer sets the pace of everything after it.

Question 4What is your position at the property?

About 72 percent of homes in this city are rented, and in a condo or a tower the wet wall is often the association's rather than yours. Who holds the duty to fix dampness changes who we talk to, what has to be put in writing, and who ends up paying for it.

Question 5How soon do you want someone out?

Deciding

The order of a Harrison job, and who signs off each step

Weigh the sequence, because doing it out of order is what costs money here. The water route closes first, the material comes out second, and the rebuild happens only once readings say the cavity is dry. Where the wall is a common element the association is the party that repairs it and the party with a right of access to do so, so a unit owner who commissions the cut can end up carrying a bill the building would have paid. Weigh the older north side separately, because not all of Harrison is new: in a pre-1978 building the paint rule applies in full, and demolition of painted surfaces is covered whatever the square footage.

  1. Whether the building predates 1978 at all

    45.1 percent of Harrison units were built in 2000 or later and 38.8 percent since 2010. The federal paint rule reaches pre-1978 housing only, so most of this stock sits outside it.

  2. Who the repair legally belongs to

    Main walls, foundations, roofs and basements are common elements under the Condominium Act. The association repairs them, and it holds the right of access to do it.

  3. Whether the water route is actually closed

    Harrison's six combined sewer outfalls all discharge to the Passaic, five of them active. A removal booked while the route is open is a removal booked twice.

The federal Renovation, Repair and Painting Rule requires anyone paid to perform work that disturbs painted surfaces in housing built before 1978 to hold EPA firm certification, and states that firms cannot advertise or perform renovation activities covered by the rule in pre-1978 homes without that certification. It applies to all firms, including sole proprietorships.

The New Jersey Condominium Act defines common elements to include, as to any improvement, the foundations, structural and bearing parts, supports, main walls, roofs, basements, halls, corridors, lobbies, stairways, elevators, entrances and exits, excluding anything specifically reserved or limited to a particular unit. Limited common elements are those common elements reserved for the use of one or more specified units.

What mold removal involves in Harrison

Local Context

What Harrison's post-2000 stock changes about a removal

A Harrison removal usually stalls on permission rather than on price. Forty five percent of the town's 10,062 units were built in 2000 or later and 38.8 percent since 2010, so the wall being opened is generally a modern assembly inside a building whose structure the association owns. That cuts both ways for you. The federal Renovation, Repair and Painting Rule only reaches housing built before 1978, so across most of this stock it does not apply and the job is simpler and cheaper. The Condominium Act, by contrast, reaches every one of those buildings.

Questions

Harrison questions to put to a removal contractor

The building wants to use its own contractor. Can I insist on mine?

Where the wet wall is a common element you usually cannot, and that is not a bad outcome. The Condominium Act makes foundations, main walls, roofs and basements common elements and gives the association access to the unit to repair them. What you can reasonably insist on is that the finding driving the scope came from somebody other than the firm carrying out the work, which is what the Department of Health recommends.

Is lead paint a concern in a 2010 building?

Very unlikely by date. The federal rule applies to housing built before 1978, and 45.1 percent of Harrison units went up in 2000 or later with 38.8 percent since 2010. On the older north side it matters a great deal, and there demolition of painted surfaces is covered by the rule regardless of how small the area is.

Next Step

The removal is arranged with a different firm from the one that wrote the report.
