Biohazard Cleanup Hanover NH
Certified remediation of unattended death, blood, trauma scenes, hoarding and sewage across Hanover - in family homes, sublet and seasonally empty property, and the rural houses out toward Etna and Lyme.
Hanover has a lot of houses that are empty on purpose. People leave for a term, a sabbatical year or a posting somewhere else, and the house is either locked up or handed to a sub-tenant who has no particular relationship with the building. Both arrangements mean small problems go unnoticed for a long time, and they mean the person who finally finds something is often not the owner and is not sure whether it is their business. If that is you: it is, and calling is the right thing to do. We will deal with the building and we will help you reach whoever needs to know.
What We Do
We remediate scenes that are not safe to clean with household products and a mop - blood, decomposition, sewage, animal waste and infectious material. Containment goes up first, the contaminated material comes out, the structure is disinfected and verified, and the waste leaves under manifest.
A death discovered days or weeks later. Fluids reach through flooring into subfloor and framing, and odour travels through the whole building, so the work goes as deep as the contamination does rather than as deep as it looks.
Quiet, fast and complete, usually for a family who has just lost someone. We work behind closed doors, in unmarked vehicles, and nobody who lives there has to look at the room again before it is finished.
Once police release the property, what investigators leave behind becomes yours to deal with - blood, fingerprint powder, evidence cuts in the drywall, chemical residue. We take all of it.
After an accident, a fall, a medical event or an injury at work. Blood is treated as potentially infectious whoever it came from, and that is what separates a remediation from a wipe-down.
Years of accumulation, often with animal waste, spoiled food and pest activity underneath it. We work at the occupant's pace and nothing is thrown away that they have not agreed to.
A backed-up main, a failed septic line or a flooded basement. Black water carries the same pathogens as raw waste, so porous material that has absorbed it comes out rather than being dried in place.
Droppings, urine, nesting material and carcasses in attics, basements, crawl spaces and camps. Dried rodent waste becomes a respiratory hazard the moment it is disturbed, which is why it is not a shop-vac job.
Homes, offices, schools and vehicles after a confirmed illness - C. diff, MRSA, norovirus, hepatitis, influenza. EPA-registered product, applied for the dwell time the label actually requires.
What We Clean
Two rooms can look identical and need completely different work. What matters is which material is contaminated, how porous it is and how long it has been there - because fluid on a sealed tile floor is a day's work, and the same fluid in old pine boards is a floor coming out.
Potentially infectious
Treated as infectious regardless of source. The visible pool is rarely the extent of it: blood wicks under baseboard, along floor seams and down through subfloor joints, so the area we open up is larger than the area you can see.
How we handle it: Containment, porous material out, disinfect, verify
Fluid, gas and insect activity
Decomposition produces fluid, gas and insect activity, and all three move. Odour is not a smell sitting in the air; it is residue on and inside materials, and it comes back if the source is only masked.
How we handle it: Deep demolition, source removal, odour treatment
Category 3 water
Raw sewage and any flood water that has contacted it. Carpet, pad, drywall below the water line and anything particleboard has absorbed it and is not salvageable, whatever a drying company tells you.
How we handle it: Extract, remove porous material, antimicrobial, dry
Airborne when disturbed
Dried droppings and urine become airborne the moment somebody sweeps them, which is the one thing nobody should do. Common in northern New Hampshire attics, barns, camps and any building left closed for a season.
How we handle it: HEPA containment, wet removal, insulation out
Mixed hazard
Rarely one hazard. Under the accumulation there is usually some mix of animal waste, spoiled food, pests and sometimes human waste, and the biohazard layer has to be separated out and handled on its own terms.
How we handle it: Sort with the occupant, biohazard layer separately
Surface contamination
A confirmed illness in a household or workplace, or the residue first responders and investigators leave behind - fingerprint powder, tear gas, extinguisher chemical. Surface work, but it needs the right product and the right dwell time.
How we handle it: EPA-registered product, labelled dwell time, wipe-down
How It Works
Nothing here is improvised on the day. The questions on the phone decide the crew and the equipment, and the work on site follows the same order whether it is one room in a city three-decker or a lake camp that has been closed since October.
What happened, where, who owns the property, whether police or the medical examiner has released it, and whether there is an insurance claim. That is enough to dispatch.
We walk the scene, find the real extent of the contamination rather than its visible edge, and give you a written scope and price before anything is touched. No charge for this.
Plastic barriers across the openings, negative air machines running, HEPA filtration, and the crew in full PPE. This is what keeps the contamination inside the one room it is already in.
Contaminated porous material comes out - flooring, subfloor, drywall, insulation, furniture - into sealed, labelled containers. We cut back to material that is clean, not to material that looks clean.
Hospital-grade disinfectant on every affected surface for its full dwell time, then odour treatment at the source. Fogging and ozone are finishing steps, never the fix.
Surface testing where the job calls for it, waste manifests and photographs for your file, and a written scope your insurer can read. We tell you plainly what needs rebuilding.
Standards and Compliance
Biohazard remediation is not an unregulated trade. A crew that cannot name the standard it works to, or tell you where your waste went, is a liability you inherit as the property owner. These are the six things worth asking any company you call, including us.
Local Notes
High-value property, a lot of it standing empty by arrangement, with owners who may be on another continent when something goes wrong.
A property shut for a term or a year accumulates the same problems a seasonal camp does - failed lines, rodent activity, and anything that happened early going unnoticed until the end. Time is the main cost driver and it runs long here.
The person on site often has no authority to approve work and no contact details beyond an email address. We will assess and document immediately and hold the quote while the owner is reached.
Approval by email with photographs and a written scope, at whatever hour suits. Nothing begins until the person responsible for the property has agreed it.
Hardwood, stone and built-in work where replacement costs real money and rarely matches. We assess what can be saved before scoping what has to go.
Outside the center it is long drives, septic, wells and serious winter. Access is stated in the quote rather than absorbed into it.
Cost
Priced per job, by what has to come out and how far the contamination reached, rather than by the hour. Here is where our work usually lands - and on most covered claims this is your insurer's bill rather than yours.
Most jobs land in a predictable band. A single-room blood or trauma cleanup typically runs $1,500 to $5,500; an unattended death found within a few days is usually $3,000 to $7,500; hoarding and advanced decomposition go higher, because far more has to come out.
| Type of cleanup | What it usually runs |
|---|---|
| Blood or bodily fluid cleanup, one room | $1,500 - $3,500 |
| Suicide or trauma scene, one room | $2,500 - $5,500 |
| Crime scene cleanup | $2,500 - $7,500 |
| Unattended death, found within days | $3,000 - $7,500 |
| Unattended death, advanced decomposition | $7,500 - $20,000 |
| Hoarding and gross filth cleanup | $5,000 - $25,000 |
| Sewage backup, Category 3 water | $2,500 - $10,000 |
| Rodent or animal waste remediation | $1,200 - $5,000 |
| Infectious disease disinfection | $600 - $3,000 |
These are the ranges we work in, not a quote. Where your job lands inside one comes down to the seven factors below - and on a covered claim most of it is your insurer's bill, not yours. Tell us what happened and we will price the actual job.
What Moves the Number
Nothing on this list is a surprise charge. They are the things we assess on site, and they are the reason an honest price cannot be given down the phone without seeing the scene.
| What we assess | How it moves the quote |
|---|---|
| How long it was there | The single biggest factor. Hours means a surface job; weeks means subfloor, framing and sometimes structure. |
| What the material is | Sealed tile and concrete clean up. Old pine boards, carpet pad, particleboard and insulation absorb, and come out. |
| How far it spread | Fluid travels under baseboard and down through floor seams, and odour travels through the whole air volume. |
| Volume to remove | One room of flooring is a different disposal weight from a hoarded three-bedroom house. |
| Access and the route out | A third-floor walk-up, no parking, a camp at the end of an unplowed road. All of it adds crew hours. |
| Odour work needed | Source removal is the fix; sealing and treating what cannot be removed is extra time on top of it. |
| Testing and documentation | Surface verification, clearance testing, and the written scope an insurer or a court will want. |
Insurance and Billing
People put off calling because they think they are about to pay twenty thousand dollars. Usually they are not. Standard homeowner and commercial property policies treat trauma and biohazard remediation as a covered loss, and several carriers have a specific allowance for it.
You pay your deductible and we invoice the insurer for the rest. The scope, the photographs, the product records and the disposal manifests go into the file in the form adjusters expect to see.
A property loss does not have to be authorised before it is made safe. We document everything from the first photograph so the claim stands up afterwards, and we can speak to your adjuster directly.
Where a death or a violent crime is involved, New Hampshire's victims' assistance program may cover cleanup costs for the family. We will tell you whether your situation is likely to qualify and what has to be filed.
Why a Remediation Firm
The reason this is not a cleaning job is that the hazard is invisible, it is infectious, and the law has an opinion about where the waste goes. Here is what actually differs.
| What differs | Certified biohazard crew | Janitorial or cleaning service | Doing it yourself |
|---|---|---|---|
| Bloodborne pathogen training | Required and current | Rarely | No |
| Containment and negative air | Standard | No | No |
| Fit-tested respirators | Every technician | No | No |
| Finds what you cannot see | Opens up to clean material | No | No |
| Waste disposal | Licensed, under manifest | Household trash, usually illegal | Household trash |
| Odour outcome | Source removed | Masked, returns | Returns |
| Insurance documentation | Scope, photos, manifests | An invoice | None |
| Who carries the exposure risk | Us, insured | Unclear | You and your family |
The part that catches people out is disposal. Putting regulated waste into a household bin or a rented dumpster is not a shortcut, it is a violation that follows the property owner - and the odour almost always comes back anyway, because the source is still under the floor.
Why Us in Hanover
The difficulty with an empty house is rarely the remediation. It is that the person standing in it cannot authorise anything, and the person who can is asleep in another hemisphere. Firms that insist on an immediate signature either lose the job or push a sub-tenant into committing somebody else's money.
We do it the other way round: assess at no charge, document everything so the clock stops, and hold the scope and price until the owner has seen it and said yes.
No charge to assess the scene, and nothing is touched before you agree the price.
We will look, photograph and write it up for whoever is on site. Nothing is committed and nothing is charged.
Scope and price by email with photographs, approved from anywhere. We do not need anyone to be in the building.
On high-value finishes we establish what can genuinely be kept before we price removal, and we document both.
Unmarked vehicles, no branding, containment inside. In a town where professional and personal circles overlap entirely, this matters.
Hanover Questions
Some of these come from owners and some from whoever is currently in the house. Both are the right person to call.
(866) 786-3078Single-room trauma and blood work falls between $1,500 and $5,500; a death found within a few days, between $3,000 and $7,500.
What tends to move a Hanover quote is not the remediation but the replacement. High-end flooring and built-in work cost considerably more to put back, which is why we spend real time establishing what can be saved.
Call us. We will come out, assess and document at no charge, and we will not ask you to authorise or pay for anything.
We then hold the written scope and price until the owner has seen it and approved it, however long that takes. Your part is making the call, which is genuinely the most useful thing you can do.
Most commonly rodent activity and nesting, or a line that failed over winter and has been standing or running since. Occasionally something more serious in a house that was supposed to be unoccupied.
Whatever it is, do not sweep, vacuum or start clearing. Dried rodent waste in particular is hazardous specifically when disturbed, and the first ten minutes of tidying is the part that puts it into the air.
Same day in normal conditions. We come up via I-89, which is a clear run outside serious winter weather.
It is a longer drive than the southern part of the state and we will give you an honest window rather than a flattering one. We arrive equipped to finish rather than to look and come back.
Yes. From Hanover we cover Etna, Lebanon, Lyme, West Lebanon, Enfield, Canaan, Plainfield and Orford, and the rest of the Upper Valley on the New Hampshire side.
For property across the river in Vermont, call and ask rather than assuming either way.
Yes, where the manager has authority to approve work. Tell us at the first call what their limit is, because it decides whether we can start or need to wait for the owner.
Either way, we document from the first photograph so no time is lost while approval is arranged.
There is no public register of remediation and we do not report jobs anywhere. What matters at sale is that the work was done properly and that you can show it.
Keep the scope, the photographs, the verification and the disposal manifests. That package answers a buyer's question far better than a conversation does.
Not from us. Unmarked vehicles, no branding on the crew, containment built inside the house and nothing left outside that explains itself.
In a small town where work and social circles are the same circles, we treat discretion as a working requirement rather than a courtesy.
One phone call, day or night. You do not need to describe it well, and you do not need to have decided anything yet. We will tell you what is involved and what it costs.
