Mold Removal in Caldwell Borough, Which Has No Flood Record
A wet Caldwell basement nearly always has a findable cause, and usually a cheap one. The borough has no repeat flooded properties and four paid flood claims in the entire history of the federal program, so what you are looking at is almost certainly something on the property itself or in the culvert beside it rather than a flood problem you cannot fix. We work out which, and if the answer is that you do not need a contractor at all, we will tell you that.

Tell us what you can see or smell, roughly where in the house it is, and which side of the building that wall is on. Direction usually tells us more than the size of the patch does, because it points at where the water arrived rather than where it ended up.

Renters are the majority here, so start with written notice
This is Caldwell borough specifically, not West Caldwell and not North Caldwell, and it is the only municipality in this area where renters are the majority at 58 percent of occupied homes, with barely a quarter of the stock single family detached. So most damp complaints here begin with a tenant, and the useful first move is written notice to the landlord rather than a quote. Be clear about what that notice rests on: there is no 72 hour landlord duty in New Jersey today, only a bill that has not passed, so what you actually have is the written notice, the implied warranty of habitability and the borough's property maintenance office. Permits come from the borough under Chapter 81 of its own code, no staff hold a formal floodplain credential, and there is no formal flood history process, although the borough says the information sits inside its incident reports, which is worth asking for. The other Caldwell specific point is the culverts. The borough has reported that Pine Brook along the Bloomfield Avenue corridor is obstructed by vegetation and debris, and that many of the culverts run through private property where it has no jurisdiction. If one crosses your lot, clearing it is yours to do, and it is probably the cheapest flood work you will ever pay for.

Senate Bill 760 of the 222nd Legislature, the Mold Safe Housing Act, was pre-filed for introduction in the 2026 session. It would require a landlord notified in writing by a tenant of a believed substantial mold hazard to investigate the condition within 72 hours, to clean and remove any visible mold from surfaces, and to fix in an expedited manner any leaking pipes, roofing or walls contributing to the wet condition. A tenant whose landlord does not comply could ask the Commissioner of Community Affairs for referral to a relocation program. The bill has not been enacted.
