Typical cleanout crew
Standard Cleaning
Standard cleaning only treats visible surfaces, leaving hidden pathogens and odors trapped deep within.
Remnant
Drug Decontamination
We eliminate biohazards at the molecular level, using advanced ATP testing to guarantee 100% decontamination.
Whether the call comes from Seattle, Seattle Valley, Liberty Lake, Cheney, Airway Heights, or Mead, a technician is close by.
What Drug Contamination Means for Seattle Property Owners
King County recorded 1,338 overdose deaths in 2023, with fentanyl the leading cause, and most of those deaths happened inside private residences. For property owners in Seattle, that context is relevant because contamination after an overdose, an arrest, or long-term use does not present visually. Fentanyl and methamphetamine residues work into carpet, bond to drywall, and settle into HVAC systems. Seattle's persistent humidity can accelerate the spread of residue into porous building materials, making the contamination harder to fully extract the longer the property sits untreated.
Washington state requires properties identified as former meth labs to be decontaminated by a certified contractor and cleared by testing before legal reoccupancy. Selling, renting, or returning to the property without completing that process exposes the owner to legal liability and the next occupant to real health risk. Remnant holds the certifications Washington requires and produces the documentation that closes the process.
Our Step-by-Step Drug Cleanup Process
Site Assessment
A technician evaluates the property, reviews any law enforcement documentation, and identifies the type and scope of contamination.
Containment Setup
Sheeting and air filtration close off the affected space so airborne particles and residues stay contained during the work.
Soft Good Removal
Mattresses, upholstery, carpet, padding, and porous items that have absorbed residue are extracted and bagged for disposal.
Surface Decontamination
Walls, ceilings, hard flooring, and fixtures are washed with chemistry suited to the specific drug residue present.
HVAC and Air Treatment
Ductwork is cleaned or replaced where needed, and HEPA scrubbers run until airborne contamination is cleared.
Clearance Testing
Surface samples are pulled and analyzed to confirm levels meet Washington decontamination standards.
How We Test and Clean Drug-Contaminated Properties in Seattle
Fentanyl residue is an absorption risk through skin and inhalation, which means Tyvek coveralls, full-face respirators rated for chemical vapor, double-layered nitrile gloves, and sealed boot covers are on before any surface is approached. The affected area is contained from the rest of the property before testing begins. In Seattle properties where humidity has driven residue deeper into porous materials, sampling covers a wider area than a visual assessment would suggest.
Chemistry is matched to the substance involved. Fentanyl and methamphetamine require different products, and using the wrong one on either produces a result that fails retesting. Post-cleanup sampling confirms levels meet Washington reoccupancy standards. All results are documented and provided to the property owner. Meth lab clearances are completed to the certification standard Washington uses for legal reoccupancy.

Cleanup Success Rate
"Found out one of our rentals had been used as a meth lab. Remnant was certified for the work and got us through clearance testing. They knew exactly what the state required."
Still Have Questions?
Are you qualified to handle drug cleanup in Washington?
Our crews are trained in OSHA bloodborne pathogen and hazardous materials protocols, follow EPA and Washington DOH guidance, and work to the same 1.5 µg/100 cm² standard the state uses.
How much does drug cleanup cost?
It varies with the size of the property and how far the residue spread, but most jobs run from a few thousand to the low five figures. We provide a written estimate after testing.
How long does the cleanup take?
A smoking-only apartment usually clears in two to three days including lab turnaround. A full lab cleanup on a house generally runs one to two weeks.
Will my insurance cover it?
Often, especially when the contamination came from a tenant, a crime, or vandalism rather than the policyholder's own use. We document everything and work directly with your adjuster.
