Restoration services
Sewage cleanup is the removal, disposal and decontamination that follows category 3 water — grossly contaminated water from a sewer line, a backed-up drain or water that came in from outside. It is a contamination problem before it is a drying problem, most porous material it touched comes out rather than being cleaned, and it is not a homeowner job at any scale.
HyreRestore is not a restoration contractor and not an insurance adjuster. We dry nothing, remediate nothing and rebuild nothing. This page explains the work so you can read a scope, judge the company that wrote it, and follow your own claim.
If this is happening right now. Keep people and pets out of the affected area and everything downstream of it. Do not walk through it and then through the rest of the house — that is how a contained problem becomes a whole-building one. Switch off the HVAC if it serves the area. Do not run water or flush anything until you know where the backup is. Then call a restoration company and your insurer, in that order. Once the property is safe and the source is stopped, you can reach HyreRestore on (866) 582-8523 — but we are a research desk, not an emergency line, and a local company will always be faster.
The short version
Source, not smell or appearance, is what classifies water. Clear water from a sewer line is still category 3.
Two questions dominate: is it still flowing, and how far did it go.
The plumbing problem is cleared or isolated; the area is closed to people and pets, including everything downstream of it. Nothing useful happens while it is still flowing.
Photographs and video of every affected area and every affected item. Contents in a sewage loss are largely non-salvageable, so the record is the claim.
Sealed barriers around the work area with air extracted through HEPA filtration, so removal work does not push contaminated aerosols into clean parts of the building.
Systems serving the area are shut down and returns and supplies sealed, so nothing is distributed while the work runs.
Respiratory protection, eye protection, gloves and boots appropriate to the scope, with a defined route in and out. The CDC’s sewage guidance is about barriers and hygiene, and it applies to everyone entering.
Solids and standing liquid extracted and disposed of under the applicable rules. This happens before any cleaning, because cleaning over soil achieves nothing.
Carpet, pad, drywall above the wicking line, wet insulation, affected particleboard and non-salvageable contents, bagged at the point of removal and taken out through the containment.
Physical cleaning of hard surfaces first — soil removal is what actually reduces contamination — then application of an appropriate antimicrobial to cleaned surfaces. Cleaning first, product second, never the reverse.
The same discipline as any water loss: a dry standard from unaffected material, air movers and dehumidifiers sized to volume and class, daily readings per location. Decontaminated but wet is not finished.
Ductwork and equipment, because a cleaned house on a contaminated system does not stay clean past the first time the fan runs.
Documented confirmation that the scope was completed and the structure reached its drying goal, before anything is closed up. Reconstruction is a separate scope, separately priced.
The dividing line is porosity. Contamination that sits on a surface can be removed; contamination absorbed into a material cannot be reliably removed from it, and the cost of trying exceeds the value of most of what is affected.
| Carpet and carpet pad | Pad is removed without exception. Carpet affected by category 3 water is normally removed too — it is porous, it is backed by more porous material, and it sits on a floor that also needs decontaminating. |
|---|---|
| Drywall and insulation | Both wick water upward and absorb what is in it. Drywall is cut back above the wicking line and wet insulation in the cavity comes out with it. |
| Particleboard, MDF and laminate | Swell, delaminate and hold contamination. Cabinetry with a particleboard carcass caught in a sewage loss is usually a replacement rather than a cleaning job. |
| Upholstered and soft contents | Furniture, mattresses, soft toys and similar are generally non-salvageable. Some textiles can be professionally laundered; that decision belongs to a contents specialist, not to optimism. |
| Hard non-porous surfaces | Concrete, tile, metal, glass, sealed and solid hardwood and finished framing are generally cleanable: physical removal of soil first, then cleaning, then drying to a measured goal. |
| Subfloor | Depends on what it is. Plywood and solid sheathing can often be cleaned and dried; OSB and particleboard that absorbed contaminated water usually cannot. |
| Ductwork and HVAC equipment | If the system was running or ducts are below the affected level, the system is part of the scope. Cleaning the rooms and leaving the ducts recontaminates the rooms. |
| Food, medicines and anything consumable | Anything in contact with the water, and anything porous nearby, is discarded. This is not a judgement call. |
Sewage work costs more per square foot than clean water for three structural reasons: more material is removed, disposal is regulated differently, and containment and protective equipment are mandatory rather than optional.
| Factor | Why it changes the number |
|---|---|
| Area affected | The base variable, and one that routinely exceeds the visible edge once wicking and tracking are mapped. |
| How much has to come out | Category 3 removes where category 1 dries. Removal is demolition plus disposal plus the rebuild that follows, so the same square footage costs several times as much. |
| Disposal | Contaminated waste follows different rules from ordinary construction debris, and requirements vary by locality. This is a real line item and a fair thing to ask about. |
| Containment and negative air | Barriers, HEPA air scrubbers and the labour to build and maintain them. |
| Protective equipment and decontamination | Consumed on every entry, and a genuine ongoing cost rather than a one-off. |
| Contents | Inventory and disposal of non-salvageable belongings, plus specialist cleaning for the minority that can be saved. |
| HVAC cleaning | Where the system was running or ducts sit at or below the affected level. |
| Structural drying | The full equipment-days arithmetic, after decontamination, on whatever is left in place. |
| The plumbing repair | Usually a separate trade and a separate invoice. Clearing a blockage is one number; replacing a collapsed line under a slab is another entirely. |
| Reconstruction | Replacing everything that was removed, priced like any other building work and driven by the finishes involved. |
HyreRestore publishes no average price for this work. Category of loss, affected area, how long equipment runs and local rebuild costs move the number far enough that a single figure would mislead more than it helped.
Sewer backup cover is the gap people discover at the worst possible moment. What follows is how standard homeowners policies commonly work, not what your policy says — check your declarations page today.
| Sewer backup is commonly excluded | Standard homeowners policies frequently exclude water that backs up through sewers or drains. It is one of the most common gaps in residential cover. |
|---|---|
| It is usually available as an endorsement | Most insurers sell sewer and drain backup coverage as an add-on, often with its own limit that may be lower than you expect. Find out whether you have it, and what the limit is, before you need it. |
| Flood is separate again | Contaminated water that entered by rising from outside is generally treated as flood, outside the homeowners policy, and covered only under a separate flood policy. |
| Cause matters | A sudden blockage is treated differently from a line that has been failing for years, and from a municipal system problem. Maintenance and gradual-damage exclusions apply here as elsewhere. |
| The failed pipe versus the damage | Policies generally cover the damage water causes rather than repairing the pipe that failed. The plumbing invoice is frequently yours. |
| Municipal responsibility | Where the backup originated in the public system, the municipality may have a claims process of its own, frequently with a short notice deadline. Ask early — the deadline can be measured in days. |
| Contents | Non-salvageable belongings are a separate part of the claim with a separate limit. The inventory and the photographs are what support it, and in a sewage loss the disposal happens fast. |
| Documentation | Photograph everything before removal begins. In this kind of loss material leaves the building quickly and for good reasons, and what you did not record is gone. |
Coverage is decided by your own policy and the peril, not by what is typical. Read the declarations page, and where the answer matters, put the question to your insurer in writing.
There is no scale at which this is a DIY job. People reasonably assume a small backup is a mop-and-bleach problem. The reason it is not: the contamination is in the water, so it is in everything porous the water reached, and bleach on a surface does nothing about what is inside the pad, the drywall or the particleboard. Meanwhile the cleanup itself aerosolises and tracks material through the rest of the house. Keep out, keep the HVAC off, and get someone with containment.
The full ten-point checklist is on choosing a restoration company.
The instinct is understandable and the logic does not hold. Contamination is carried in the water, so it is inside every porous material the water reached; disinfecting a surface does nothing about what is in the pad, the drywall or the cabinet carcass. Worse, the cleanup itself aerosolises material and tracks it through the house on shoes and equipment.
This is the most common way a contained problem becomes a whole-building one, and it usually happens in the first ten minutes before anyone has thought about it. Establish one route in, keep everyone else out, and take shoes off at the boundary.
A system serving the affected area distributes contamination to every room it reaches, including rooms that were never touched. Switch it off before you do anything else, and leave it off until someone has assessed it.
Sentiment is understandable and the answer is still no. These items are porous, backed by porous material, and cannot be reliably decontaminated. Photograph and inventory them for the claim, then let them go.
Antimicrobials work on cleaned surfaces. Sprayed over gross contamination they do very little, and they give a false sense that the area has been dealt with. Physical removal first, cleaning second, product third — in that order, every time.
A structure can be thoroughly cleaned and still be wet inside the assemblies. Closing it up at that point produces a mould problem on top of a sewage one. The drying goal and the daily log apply here exactly as in any water loss.
We would not, and the reason is not squeamishness. The contamination is carried in the water, so it is inside every porous material the water reached — carpet pad, drywall, insulation, particleboard — and no amount of surface disinfectant addresses what is inside them. The cleanup itself also aerosolises material and tracks it around on shoes and equipment, which is how a problem confined to one room ends up everywhere. Keep people and pets out, switch the HVAC off, and get someone with containment and protective equipment.
The source and the degree of contamination, not the volume or the appearance. Under the industry standard, category 3 is grossly contaminated water: sewage, water from beyond the toilet trap, and water that rose in from outside carrying whatever it crossed. Clear-looking water from a sewer line is still category 3. Category also degrades with time — clean water sitting in contact with building materials, soil and contents for days deteriorates into a higher category, which is why response speed matters so much.
Generally everything porous that the water touched: carpet and pad, affected drywall and the insulation behind it, particleboard and MDF including most cabinet carcasses, upholstered furniture, mattresses, soft toys, and all food, medicines and consumables in the area. Hard non-porous surfaces — concrete, tile, metal, glass, finished framing, solid hardwood — can generally be cleaned and kept. Some textiles can be professionally laundered, which is a contents specialist’s call rather than a hopeful one.
Public health agencies treat sewage as a source of exposure to bacteria, viruses and parasites, and the CDC’s practical guidance is about barriers and hygiene: protective equipment for anyone who has to be in it, no eating, drinking or smoking in the area, cover any cuts, and wash thoroughly afterwards. What we cannot do is tell you what any particular exposure means for you — that is a question for a doctor, and if anyone in the household develops symptoms after exposure, that is the call to make. Any contractor offering a health assessment is outside their competence.
Frequently not under the base policy. Standard homeowners policies commonly exclude water that backs up through sewers or drains, and coverage is sold separately as an endorsement — often with its own limit, and often a lower one than people expect. It is one of the most common gaps in residential cover and one of the cheapest to close. Check your declarations page for a sewer and drain backup endorsement now, while nothing is happening.
Where the problem originated in the public system, the municipality may have its own claims process, and these frequently carry short notice deadlines — sometimes measured in days rather than weeks. Report it to the municipality immediately as well as to your insurer, ask specifically about the notice deadline, and keep everything: photographs, dates, who you spoke to. Whether the municipality accepts responsibility is a separate question from whether you should notify it promptly. You should.
The decontamination and removal phase is usually faster than people expect, because so much material simply leaves rather than being treated — often a matter of days for a contained residential backup. The drying that follows takes as long as the readings take to reach goal, exactly as in any water loss. The reconstruction afterwards is a building job on its own timeline. The variable that stretches everything is the plumbing repair, which can be trivial or can involve excavating a line under a slab.
They are part of it and not the main part. Antimicrobials work on surfaces that have already been physically cleaned — removing the soil is what actually reduces contamination, and product applied over it does very little while looking like it did something. They also do nothing about contamination inside porous material, which is why removal rather than treatment is the strategy for anything absorbent. If a proposal is built around fogging or spraying rather than removing, ask what is coming out.
If it was running while the water was there, or if any ductwork sits at or below the affected level, yes. A forced-air system moves whatever it draws in to every room it serves, including rooms the water never reached. Switching it off early limits the problem considerably. Where it did run, duct and equipment cleaning belongs in the scope — otherwise the cleaned house recontaminates itself the first time the fan starts.
Sometimes, depending on the layout, the size of the affected area, whether the containment can isolate it from where you live, and whether the bathrooms and kitchen are usable. Ask before the work is scheduled, and ask specifically which areas are off limits and how you will move around the house. If the property is genuinely uninhabitable, many policies cover the extra cost of living elsewhere — keep receipts from the first night.
Technically they overlap heavily: floodwater that crossed ground, roads and sewers is treated as category 3 and the decontamination work looks much the same. The difference that matters to you is the insurance. A sewer backup may be covered by a homeowners endorsement; floodwater rising from outside is generally covered only under a separate flood policy. Same water classification, same work, entirely different paperwork — which is why establishing where the water came from is the first thing anyone should pin down.
