Water where it shouldn't be, a sewer backup or mold you can smell? Say what happened and where, and one call connects you with a restoration company that serves your Bergen County town.
Number for Water Damage, Fire, Mold & Sewage
Calls answered 24/7. No obligation to book.
Undercroft Restoration is a free referral service, not a restoration company. Calls are connected to independent local service providers that serve your area, and calls may be recorded. The work is done by those providers, not by this site.
Different problems need different kinds of companies. Find the line that matches what you're looking at, and follow it for what to do first.
Water spreading across a floor or coming through a ceiling needs to come out fast, before it soaks into walls and the floor below. Stay away from outlets and the panel if the water is near them. If you need an emergency restoration company tonight, start with emergency water removal.
A burst supply line, a water heater that let go, a dishwasher, or water coming down from the apartment above. Shut off the water, photograph everything, then see water damage restoration for the whole job from drying to rebuild.
Groundwater at the floor joint, a window well that filled, a sump pump that quit in the storm. Pumping, tear-out and drying are on flooded basement cleanup. Pump replacement and backups are on sump pump.
River, brook or street water is contaminated and insured differently from a pipe leak. Photograph before anything goes to the curb, then see storm and flood damage.
Dark water from a floor drain or a toilet overflowing on its own is a sewage backup. Stop using water, keep kids and pets away, and see sewage cleanup.
Spots on a wall, a musty closet, or a smell with nothing visible. For removal and fixing the moisture, see mold remediation. If you can't find it, or you're buying or selling, see mold inspection and testing.
If you clean up the same basement after every heavy rain, the problem is groundwater, and cleanup alone won't fix it. See basement waterproofing.
Here's the straight version, because you should know who you're calling.
Undercroft Restoration is a referral service. When you call (201) 409-9820 and give your town and what happened, your call is connected to an independent, third-party company that serves your area and handles that kind of job. That company comes out, inspects, gives you a written scope and does the work.
Undercroft Restoration doesn't do the work, doesn't set prices, and doesn't hold contractor licenses or certifications or show anyone's registration number as its own. What the line does is get you through to the right kind of company, any hour, with one call instead of ten.
When the company calls back or arrives, ask them for:
Every page on this site is written to help you ask those questions, whoever ends up doing the job.
You can't judge a crew by its website, but you can judge it by how it handles the job. A good restoration company:
Hold whoever you're connected with to that list.
Calls cover three kinds of work: property damage restoration after water gets in, water damage and mold remediation once growth has started, and waterproofing to keep it from happening again.
Emergency water removal and water damage restoration (see the guide above), plus water mitigation for drying with daily readings and water damage repair for drywall, floors and paint after it's dry. Flooded basements, storm and flood damage, and sewage cleanup are in the guide above too.
Mold remediation and inspection (above), plus black mold removal for dark growth in bathrooms and on wet drywall, and basement and attic mold for the spaces that stay damp longest.
Basement waterproofing and sump pumps (above), plus french drains, crawl space encapsulation and foundation crack repair.
What your policy likely covers, what to photograph, and New Jersey's claim deadlines are on insurance claims help.
Every service page follows the same approach: what goes wrong in Bergen County homes, what a proper job looks like step by step, the questions to ask before anyone starts, and honest answers to the questions people actually search. None of them quote prices, because no honest company can price water or mold damage without seeing it.
The tidal Hackensack River runs down the middle of the county and along Hackensack's eastern edge. River towns have flooded in Sandy, Ida and as recently as April 2022, when the river crested at 8.57 feet at New Milford.
Parts of Hackensack west of the railroad, and parts of Fort Lee and Ridgefield Park, still have combined sewers, where rainwater and wastewater share one pipe. In heavy rain, that pipe fills and sewage can come back up basement drains.
About half of Hackensack's homes were built before 1970, and much of the county was built out in the postwar boom. Block foundations, original sump pits and old footing drains are why so many basements take on water.
Along the Palisades and on Hackensack's Prospect Avenue, most water damage is a leak from one unit into the ones below. A supply line on the 18th floor can put water in three apartments, and the super, the condo board and several insurers all get involved.
On July 27 and 28, 2026, River Edge recorded 6.06 inches of rain. Six weeks later, on Sunday, September 13, 2026, more than 5 inches fell in about three hours in Paramus and nearby towns. Storms like those overwhelm drains everywhere, not just near rivers.
This site started with Hackensack, the county seat, and was built outward from there. Hackensack has a bit of everything that goes wrong with water in North Jersey: a tidal river on its east side, brooks that flood around Johnson Avenue, combined sewers west of the railroad, pre-war houses in the Fairmount section and high-rises on Prospect Avenue. If a page on this site explains something, it was usually learned there first.
The detailed town guides cover Hackensack, Teaneck across the river, Paramus along the Saddle River, and the Fort Lee high-rises on the Palisades. The county guide lists all 70 towns and where their water problems tend to come from. Calls from every one of those towns are connected the same way, from Mahwah and Montvale in the north to Lyndhurst and North Arlington in the south. Other New Jersey counties will follow.
You'll see both words, and people use them interchangeably. They aren't quite the same. Remediation means removing something harmful: mold, sewage, contaminated floodwater. It involves containment, removing what can't be cleaned and disinfecting what's left. Restoration puts the home back: drying, rebuilding drywall and floors, repainting. Many companies do both, and many jobs need both, usually in that order. You don't need to know which one to ask for. Say what happened, and your call goes to a company that handles it.
About 64 percent of Hackensack households rent, and much of the county lives in condos, co-ops and apartments. The call works the same for everyone, but the first step is different:
Calls answered 24/7. Pick the number for your problem, then say your town and what happened.
No. Undercroft Restoration is a referral service. When you call, you're connected with an independent company that serves your town, and that company does the work.
No. There's no charge to call and no obligation to book anything. If the company you're connected with comes out and you decide not to go ahead, that's your call.
An independent, third-party company that serves your area and handles your kind of problem. Ask them for their NJ home improvement registration number, proof of insurance and a written scope.
All 70 towns in Bergen County, from Hackensack, Teaneck, Paramus and Fort Lee to Mahwah, Ridgewood, Englewood and Lyndhurst. Which companies are available can vary by area and time of day.
Yes. Calls are answered 24/7, including nights, weekends and holidays.
No. Every job depends on what got wet, how much and what kind of water. The company you're connected with will look at the damage and give you a written scope before any work starts.
It depends on where the water came from. Sudden pipe bursts are usually covered; floods need a flood policy; sewer backups usually need an endorsement. Photograph everything before it's moved or thrown out, and tell your insurer promptly. The insurance claims help page walks through what to keep and New Jersey's claim deadlines.
Call your landlord or super first so they can stop the water and handle the building. You can call this line too, especially to get your unit and belongings documented.
All three. Calls about mold, waterproofing, sump pumps, French drains, crawl spaces and foundation cracks are connected the same way as water damage calls. Often they're connected problems: a leak that wasn't dried becomes mold, and a basement that floods every storm needs waterproofing after the cleanup.
Calls answered 24/7. Have your town and what happened ready when you call.
