Biohazard and hoarding work in New Jersey runs about $3,000 to $12,000 for cleanup alone in 2026, and $12,000 to $30,000 when the floor, walls and systems underneath have to be rebuilt. Here is how it works, said plainly: contaminated material — blood, sewage, needles, animal waste, medical sharps — is handled by certified biohazard technicians we bring in and stand behind. Then our own crew does everything after that: the tear-out, the subfloor, the framing, the wiring, the drywall, the floors and the paint. One number to call, one written price, and unmarked trucks at the curb if that's what you want.

Blood and body fluids, sewage and heavy animal waste all carry things you can't see. Kids, pets and anyone with a weak immune system stay out of the whole area. Don't run the central heat or AC through it. If it's sewage, stop using every drain, toilet and washing machine in the house — anything you send down goes right back into that room.
A household vacuum aerosolizes what's on the floor and a mop just spreads it into the grout. Bleach doesn't reach into carpet pad, drywall or subfloor. In a hoarded house, moving stacks can collapse them, and there are almost always sharps, spoiled food, rodent nests or exposed wiring in the layers. If there's a medical or police matter, leave it exactly as it is until you're told otherwise.
A real person answers, day or night, and won't make you explain it twice. Tell us roughly what's in the room and how big it is. We'll tell you on the phone what the certified techs have to handle, what our crew handles after, and when we can be there — often the same day, and in an unmarked truck if you ask.
We are a general contractor, not a biohazard company, and we're not going to pretend otherwise. Anything contaminated — blood and body fluids, sewage, sharps, heavy animal waste, medical waste — is handled by certified biohazard technicians we bring in on the job. They do the removal, the decontamination and the regulated-waste disposal with the paperwork that comes with it. We coordinate them, we're on site, and their work is on your one written price.
Then our crew takes over, and that's the bigger half of most jobs. Contaminated flooring, subfloor and drywall come out. Rotted joists and sill plates get sisters or get replaced. The wiring a rodent chewed through gets redone by our electricians. The drain the sewage came out of gets fixed by our plumber. Then insulation, drywall, trim, floors and paint, and the room is a room again.
One phone number, one foreman, one price. You don't get handed off to a rebuild contractor when the hard part is done.
Sewage is what the trade calls Category 3 water: it carries bacteria, and it turns porous material into waste the moment it touches it. That rule decides most of the job. Carpet and pad, particleboard furniture, upholstered pieces, mattresses, drywall from the floor up to about two feet above the high-water line, and any insulation it reached all come out and go in the dumpster. Tile, sealed concrete, solid wood framing, plastic and metal can be cleaned and disinfected and usually stay.
Then we deal with why it happened. A main line full of roots, a collapsed clay or cast-iron section, a failed ejector pump, or a town main that surcharged during a storm — our camera tells us which, and our plumber fixes it. If the town line backs up into your basement more than once, a backwater valve is the permanent answer and we'll price it on the same sheet.
A hoarding job is a people job with a dumpster attached. We work at the family's pace and by the rules you set before we start: what's sorted, what's saved, what goes straight out. Every crew member knows to stop and hand over anything that looks like money, jewelry, photographs, military papers, deeds, titles or a bank statement — it goes in a marked find box that you go through with us at the end of every day, not into a bag.
The house underneath is almost always its own project. Under two feet of material we usually find rotted subfloor and joists from long-forgotten leaks, urine-saturated flooring, chewed wiring, dead or dangerous appliances, a furnace that hasn't been serviced in fifteen years, and windows and doors blocked so badly that there's no legal way out of a bedroom. We photograph it, price the repairs separately so you can choose what to do now and what to do later, and we tell you honestly if the house is worth the rebuild or if it's a sell-as-is.
For estates, executors and landlords we can run the whole thing on a deadline: cleanout, repairs, paint and floors, back on the market. Most of our hoarding jobs start with an adult child who lives out of state and has one week off. That works.

typical fixed-price range — your exact number goes in writing after a free visit
A small, contained biohazard cleanup — one room, certified technicians, disinfection and regulated disposal — starts at $695 and usually lands between $1.5K and $5K. A trauma scene with material through a floor and into a subfloor runs $4K – $10K. A finished-basement sewage backup runs $2.5K – $9K for cleanup and removal. A hoarding cleanout is priced by volume and by how much sorting you want: a single room is $1.5K – $4K, a full house with dumpsters, labor and disposal is $8K – $20K. The rebuild after any of it — subfloor, drywall, floors, paint, sometimes wiring and plumbing — is quoted on its own lines and typically adds $4K – $20K.
How we beat the big chains: National franchises sell the cleanup and then hand you a phone number for the rebuild, so you pay two markups and manage two companies through the worst week of your year. No franchise fees, no commissioned salesmen, no rented subcontractors — that's typically 15–30% under national-brand quotes for the same or better spec. Bring us any written quote and we'll match the scope line by line.
“The cleanup company took the mess out and left me with a hole in the floor and bare studs. Then nobody wanted the rebuild job because it was 'too small'.”
“Three trucks with a giant logo sat outside my mother's house for four days. The whole street knew her business.”
“They cleaned out my father's house and his wedding ring and his discharge papers went out in a dumpster.”

A small contained biohazard cleanup starts around $695 and usually lands between $1,500 and $5,000. A trauma scene that soaked into flooring runs $4,000 to $10,000. A hoarding cleanout is $1,500 to $4,000 for one room and $8,000 to $20,000 for a full house. The rebuild afterward typically adds $4,000 to $20,000 and is priced on its own lines.
No, and we'll say so up front. Contaminated material is removed and decontaminated by certified biohazard technicians we bring in and coordinate, with proper regulated-waste disposal. Our own crew does the demolition, the structural repairs and the full rebuild. It's one price and one foreman, but two sets of hands with two different specialties.
Not from us. Unmarked trucks on request, dumpsters staged out of sight or in and out on the same day, crews briefed not to talk about the job outside the house, and early or weekend starts if the street is busy. We've done this on blocks where nobody found out.
Sewage backup is usually covered only if you carry the sewer and drain backup rider — check the policy before you file. Trauma scene cleanup is often covered under dwelling coverage. Hoarding cleanouts are essentially never covered, though the water damage, rot or rodent damage found underneath sometimes is. We document all of it either way.
One heavy room with sorting is one to two days. A full single-family house is usually four days to two weeks depending on how much gets sorted versus discarded, and how many dumpster pulls the driveway allows. Repairs underneath add on top of that, and we'll give you a written timeline before we start.
Usually yes, and we'll tell you honestly if it isn't. After the contaminated material is gone and the structure is dry and disinfected, the questions are the boring ones: is the subfloor sound, does the wiring pass, does the heat work, is there a real way out of every bedroom. We check all of that, photograph it, and price what it takes to fix.
