Paterson's housing stock is old, and older buildings leak in places that newer construction does not: parapet flashing on flat-roof row homes, mortar joints in unreinforced masonry, brick-cavity walls that funnel rain to the interior face of the backup wythe. Mold follows moisture wherever it settles, and in a basement apartment on Oliver Street or a third-floor walk-up near Eastside Park, the colony is often well established before anyone sees it on the surface. Paterson Water Repair builds a negative-pressure containment barrier before any material is removed, runs HEPA-filtered air scrubbers through the remediation, and verifies clearance with post-work testing rather than a visual sign-off.

Why Bleach Does Not Kill Mold (And What Actually Does)
The single most common mold-remediation myth: bleach kills mold. It does not. Bleach is mostly water plus sodium hypochlorite. It can lighten surface staining (which is why people think it worked) but the chlorine evaporates while the water soaks into porous material, feeding the fungal growth underneath. Within weeks the visible mold returns.
What actually works: physical removal of the contaminated substrate. If mold is on porous material (drywall, insulation, untreated wood, carpet pad), remove the material. If mold is on hard non-porous surfaces (sealed concrete, finished wood, ceramic tile), HEPA vacuum + wipe with EPA-registered antimicrobial. Either way, the source moisture has to be eliminated first or the mold returns regardless of what cleaning was done.
Antimicrobial chemicals have a place in our protocol โ applied AFTER source removal, on remaining hard surfaces, as a final step before reconstruction. They do not substitute for source removal. A Paterson restorer who promises to "spray and seal" without removing contaminated substrate is selling a treatment that fails predictably.
IICRC S520 Protocol โ What Proper Mold Remediation Looks Like
The IICRC S520 standard defines the protocol for safe, effective mold remediation. It is not legally required in NJ but it is what good restorers follow because it is the only approach that actually works long-term. The shortcut versions (spray bleach on it, paint over it, fog with antimicrobial, leave the source moisture in place) all fail within months.
The protocol has five phases: assessment (where is the mold, how extensive, what species, source moisture identified and stopped), containment (negative-air pressure differential between affected and unaffected spaces, plastic sheeting, HEPA-filtered air scrubbers running continuously), source removal (porous materials with growth get removed and bagged for disposal โ drywall to documented flood line, insulation, untreated wood), HEPA cleaning (all hard surfaces in the containment), and verification (visual inspection + optional third-party air sampling to confirm the contamination has been removed).
Reconstruction only starts AFTER verification clears. New material does not go up against contaminated substrate. Skipping verification is how you end up with mold returning behind a freshly-painted wall.
Mold Remediation and the rest of your recovery
A property loss in Paterson rarely stays in one lane โ mold remediation often overlaps with burst pipe response, post-fire restoration, storm cleanup, sewage cleanup, rebuild and restoration, and our crew handles all of it under one contract. We dispatch the same standard to Mold Remediation in Clifton, Passaic mold remediation, Garfield mold remediation, Elmwood Park mold remediation and everywhere else across Passaic County.
