Sewage Cleanup and Sanitization in Hillside

When Tropical Storm Ida pushed the Elizabeth River over its banks in 2021, dozens of Hillside basements filled with a mix of stormwater and raw sewage — and many of those homes were already working with aging cast-iron drains and galvanized supply lines that had been quietly corroding since the Truman administration. That combination of old infrastructure and low-lying ground makes sewage backup a recurring reality in this township, not a freak event. If you’re dealing with it now in the 07205 ZIP code, the clock matters: raw sewage introduces Category 3 water — the most contaminated classification — and the IICRC S500 standard treats it as a biohazard from the moment it enters the structure.

Why Hillside Properties See Sewage Backup More Than Most

Hillside’s housing stock tells the story. The colonials, two-families, and postwar capes that line streets through neighborhoods like Saybrook and Winans were built between roughly 1925 and 1955, which means their original cast-iron drain stacks and clay sewer laterals are now 70 to 100 years old. Cast iron corrodes from the inside out; clay laterals crack under root intrusion and soil shift. When a heavy summer downpour overwhelms the municipal combined sewer system — and Union County’s older combined systems do surcharge during intense rain — that pressure has nowhere to go except back up through floor drains and basement toilets.

The Elizabeth River’s eastern corridor through town amplifies the problem. Properties on low ground near Evergreen Cemetery and the Conant Street area sit at elevations where even a modest river rise can push groundwater into foundation walls faster than a sump pump can keep up. Sump-pump failures during summer downpours are among the most common calls we receive from this part of the township, and when the pump fails during a surcharging sewer event, the backup is rarely clean water.

Our Sewage Cleanup and Sanitization Process in Hillside

Sewage cleanup in an older Hillside home requires a different approach than a newer build. The finished and semi-finished basements common here often have wood-framed walls, drop ceilings, and carpet or laminate over concrete — materials that wick contaminated water quickly and cannot be dried in place once Category 3 exposure is confirmed.

Our process moves in a deliberate sequence:

1. Containment and PPE staging — We establish a contamination boundary before any equipment enters the affected area to prevent cross-contamination to upper floors.
2. Extraction — Truck-mounted and portable extraction units remove standing sewage. In tight basement stairwells common to 1940s capes, portable units often have to do the heavy lifting.
3. Controlled demolition — Saturated drywall, insulation, and flooring below the contamination line come out. In homes with original plaster-and-lath walls — still present in some Hillside Center properties — we assess carefully, because plaster can hold contamination in the lath cavity even when the surface looks dry.
4. Antimicrobial treatment — EPA-registered disinfectants are applied to all affected structural surfaces, not just the floor.
5. Drying and monitoring — Industrial dehumidifiers and air movers run until moisture readings return to pre-loss baselines, verified with thermal imaging and pin meters.
6. Post-remediation documentation — We photograph and document every step for your insurance carrier.

Reaching Hillside from Kenilworth

Our team operates out of Kenilworth, which puts us a short drive from Hillside via Route 22 or North Avenue depending on traffic. We’re available 24/7, so whether the backup surfaces at 2 a.m. or during a weekend storm, you can reach us at (855) 650-7422. The Route 22 corridor also means we’re regularly working commercial losses in Hillside’s retail and warehouse properties — sprinkler discharges, roof leaks, and overnight flooding in the Conant Street industrial zone are a consistent part of our work here, and that familiarity with the area helps us move fast when a residential call comes in.

Hillside Insurance Coordination

Sewage backup coverage is a policy endorsement, not a standard homeowner’s policy inclusion — and many Hillside homeowners discover that gap only after the event. We document the loss thoroughly from the first hour on-site: photos of standing sewage levels, moisture readings, contaminated materials before removal, and a written scope of work. That documentation is what your adjuster needs to process the claim. We bill carriers directly and work with most major insurers. If your policy doesn’t include sewage backup coverage, we’ll walk you through the out-of-pocket scope so there are no surprises.

Local Note

In Hillside’s older two-family homes — particularly the side-by-side configurations common through Winans and Coe’s Corner — the drain stacks for both units often share a single lateral to the street. When one unit backs up, the other unit’s plumbing can be affected too, even if the second tenant sees no visible sewage. We scope both units when we’re called to a two-family, because treating only the visible side and missing active contamination in the shared wall cavity is how mold problems develop three weeks later.

If sewage has reached your Hillside basement, don’t wait to see whether the smell clears on its own. Call (855) 650-7422 — we’re available around the clock and can begin the extraction and sanitization process before secondary damage compounds the loss.
