Which of the three is your block?
Give us the street and the floor you are on. We will name the likely water path before anyone talks about scope, which is how you tell a sound quote from a sales pitch.
Which Jersey City office to call, and which pipe is yours
Two city offices handle the two halves of a damp problem here, and sending it to the wrong one is the usual reason nothing happens. The Division of Housing Preservation runs the Office of Landlord Tenant Relations and the rental registries, while the Division of the Construction Code Official handles the building itself and registers every non state licensed contractor working in the city. Mold work is not a state licensed trade, so that registration is the thing to ask a company for, not just a state home improvement license. On the repair side the city publishes its own ordinary maintenance list, and painting, wall covering, replacing flooring, interior trim, insulation other than foam plastic, and gutters and leaders all need no permit at all. On a Heights hillside new leaders are often the highest value moisture repair available and nothing is holding it up. Ownership decides the rest. About 72 percent of Jersey City households rent, so for most people the first move is a dated written notice of the water source rather than a contractor. In a condominium the New Jersey Condominium Act puts foundations, main walls, roofs and basements among the common elements, which means the wet wall is usually the association's to open and paying to do it yourself can cost you the claim. Rent control is worth checking too, because properties of one to four units are exempt from it and a substantial moisture repair in a controlled building turns into a capital improvement argument later.
