Sewage backup is a health emergency. Not a cleaning project.

Black water - what the restoration industry calls Category 3 - contains bacteria, viruses (including hepatitis), and parasites. Bleach does not handle it. DIY cleanup spreads contamination and can land you in the hospital. This is one of the few situations where the right answer is always: stop, leave the area, call a professional.

Our team holds biohazard and bloodborne pathogen training in addition to our IICRC, OSHA, and AHERA certifications. We have the containment equipment, PPE, and IICRC-standard protocols to handle Category 3 contamination safely.

Our Full Cat 3 Process

Containment first. Then removal. Then restoration.

Every step follows IICRC Category 3 water damage protocols. Done right, your home comes back safe to occupy and odor-free.

See the full step-by-step process

Day 1 — Hour 0

Emergency call & immediate guidance

You call 253-553-6435. The first thing we do, before dispatching, is get everyone out of the affected area - including pets. We give you immediate safety guidance on the phone: do not flush, do not run water, shut off the water main if safe to do so, do not run HVAC.

Then a crew is dispatched with biohazard PPE and Cat 3 containment materials.

Day 1 — Hours 1-2

Containment construction

Before any cleanup begins, the affected area gets fully isolated. Plastic barriers seal off doorways. Negative air pressure with HEPA filtration ensures contaminated air stays in the work zone. HVAC vents in the affected area get sealed.

Crew suits up in full PPE - tyvek suits, respirators, gloves, eye protection. This is not "cleaning gear" - it is biohazard response gear.

Day 1 — Hours 2-4

Source stop & assessment

If sewage is still actively backing up, that gets stopped first - shutoff valves, blocked drains, whatever is needed. For municipal main backups, that may mean coordinating with the city water/sewer department.

Then we assess the full extent of contamination. Cat 3 water travels along the same paths as clean water but the cleanup standard is much higher.

Day 1 — Hours 3-8

Removal & biohazard disposal

Contaminated water is extracted. Porous materials that were exposed - drywall, carpet, carpet padding, insulation, baseboards - get removed. Cat 3 standards mean these materials cannot be safely decontaminated; they have to be removed.

All removed materials are bagged inside the containment zone as biohazard waste and disposed of through approved channels. Not into your regular trash, not staged in your driveway.

Day 2 — Treatment

HEPA filtration & biocide treatment

Air inside containment continues running through HEPA scrubbers throughout the process. Once gross contamination is removed, every remaining surface gets treated with EPA-registered antimicrobials rated for Category 3 contamination.

This is not bleach. These are commercial biocides designed for the specific pathogens present in sewage water. Multiple passes, with dwell time for the products to work.

Days 2-4 — Drying

Structural drying

Once the area is decontaminated, structural drying begins. Same equipment and process as water damage drying - air movers, dehumidifiers, daily moisture monitoring - inside the containment zone.

Containment stays up throughout drying. Equipment is cleaned and decontaminated when removed.

Day 4-5 — Final Sanitization

Sanitization & odor removal

Final sanitization pass on all surfaces. Thermal fogging or ozone treatment for any residual odor in structural cavities. Verification of air quality.

Optional third-party clearance testing for higher-end jobs or when health concerns are involved.

Required by Washington State Law

Asbestos testing comes first — here's how we keep it moving.

Before we demolish anything, Washington State law requires an asbestos survey - on every home, whether yours was built in 1906 or yesterday. It is out of our hands, so we built our process around it instead of letting it hold up your job. Here is how it actually goes:

We collect the samples

Before any demolition, we take small samples from everywhere we plan to work - drywall, vinyl flooring, the mastic underneath, anything that will be disturbed - and drop them at the lab. Washington State law requires this on every home, new or old, so we just build it into the job.

We rush the lab and wait on results

Once the samples are at the lab, we put a rush on them. We will always work to get the results turned around as fast as possible, so the job keeps flowing smoothly.

Meanwhile, we prep the home

While the samples are at the lab, we get your home ready for demolition - setting up containment, laying floor protection, staging equipment - and start your insurance paperwork if that applies. The moment results are in, we are already set up and ready to go, so no time is lost.

One clarification: we are a mitigation company, not an asbestos abatement firm. Asbestos can show up randomly, and you will never know it is there until it is tested for. We take the necessary precautions to protect your home the right way, from start to finish. If a sample comes back positive, we schedule the abatement team to take care of it. This goes through your insurance as well, at no extra cost to you.

What to do before we arrive

Get everyone out of the affected area, including pets. No exceptions.
Do not flush toilets, run water, or use anything that drains to the affected system.
If safe, shut off water to the home at the main.
Do not attempt to clean it yourself. Photo-document for your insurance, then stay out.
Do not run your HVAC system - it can spread contaminated air throughout the home.

What causes sewage backups

The most common causes we see:

Main sewer line blockages (tree roots, accumulated debris, structural collapse)
Municipal sewer backups during heavy rain events
Septic system failures (full tank, drain field saturation, mechanical failure)
Toilet or drain overflow due to a clog downstream
Foundation cracks allowing groundwater + sewage mixing during high water table events

Insurance coverage for sewage backups

Standard homeowners policies typically exclude sewage backup unless you have a specific rider added. Many homeowners find out about this exclusion the hard way. We document the loss completely regardless of coverage, and we are honest with you up front about what is likely to be covered before work begins.

Containment & Protection

Tight containment. A clean, livable home.

Restoration is messy work - but your home should never feel like a construction zone. Before we touch anything, we build clean, professional containment around the affected area so the rest of your house stays exactly that: the rest of your house.

Sealed, professional barriers

Poly sheeting and zipper-door entries seal the work zone off from your living space. Dust, debris, and contaminants stay inside the containment - not drifting through your home.

Protected pathways

We lay floor and surface protection along every path we use, so you can move through your home safely and cleanly - whether we are on site or not.

Air kept under control

Where it is needed, we run negative-air control and air scrubbers so airborne particles are captured and filtered, keeping your air clean while we work.

Clean enough to leave standing

Our containment is tight, organized, and something we are proud to leave up overnight. Your home stays livable - kids, pets, and daily life keep moving around our work.

FAQs

Frequently Asked Questions

How dangerous is sewage backup, really?

Very. It contains bacteria, viruses (including hepatitis), and parasites. Even brief skin contact carries infection risk. Do not enter the area; call us. This is the one situation where the right answer is always stop, leave, call a pro.

Will my homeowners insurance cover sewage backup?

Only if you have a specific sewage backup rider - most basic policies do not include it. We help you document the loss regardless and are upfront about what is likely covered before work starts.

Can the contaminated materials be saved?

Hard surfaces (tile, sealed concrete, metal) can be cleaned and disinfected. Porous materials (drywall, carpet, padding, insulation) almost always have to be removed and replaced. We explain why for everything we remove.

How long does sewage cleanup take?

Typically 2 to 4 days for cleanup and sanitation, plus drying time and any repairs. Larger jobs go longer. We give you a realistic timeline upfront.

Will the smell go away?

Yes, completely - when done right. Sewage odor lives in porous materials and structural cavities. We remove what is saturated, sanitize the rest, deodorize the air, and verify before we close out.

Why can't I just clean it with bleach?

Bleach is a surface disinfectant, not a sanitization protocol. It does not penetrate porous materials, it does not kill all the relevant pathogens, and it does not address contamination wicking into your subfloor or behind your baseboards.
