Drug Decontamination in Denver, CO

What Is Drug Decontamination?

Drug decontamination is the removal of residue left by drug use, handling, or production. Residue can settle on surfaces, get into porous materials, or reach ductwork. 



The substance involved and where it may have spread determine what can be cleaned, what needs to be removed, and whether independent testing is needed.

Our Drug Decontamination Process

We explain the scope of work before cleanup begins, including where independent assessment or clearance testing fits into the plan.

24/7 Response & On-Site Safety Check

Call us anytime. On site, we check where residue may have spread, identify areas that need to stay closed, and explain whether an independent assessment is needed before cleanup.

Surface & Duct Cleaning

We clean and treat affected walls, floors, and other surfaces using methods suited to the residue and materials. We include vents and ductwork in the cleanup when the assessment shows they were affected.

Containment & HEPA Air Filtration

We seal off the work area with barriers and use HEPA air scrubbers as appropriate to help keep airborne particles from spreading into unaffected rooms or units.

Third-Party Clearance Testing

When needed, an independent professional collects samples after cleanup and compares lab results with applicable Colorado standards and other cleanup criteria. We complete any additional cleaning before retesting.

Material Removal & Safe Disposal

We remove affected materials that can’t be safely cleaned, such as damaged drywall or carpet. We handle and dispose of those materials according to the requirements for the contamination involved.

Repairs & Rebuilding

Once cleanup and any required clearance testing are complete, our in-house general construction team can replace removed materials, repair finishes, and rebuild affected areas.

Drug Decontamination FAQs

  • What is drug decontamination?

    It’s a cleanup process for property affected by drug residue. Depending on the situation, it can include isolating rooms, removing materials that can’t be safely cleaned, treating surfaces and ductwork, and having an independent professional test the area afterward.

  • Who cleans up fentanyl and meth in Denver?

    4PRO provides fentanyl residue cleanup in Denver. For suspected meth contamination, a Colorado-certified consultant can assess and test the property. 


    When cleanup is required under Colorado’s methamphetamine rules, it must be performed by a contractor approved by the Colorado Department of Public Health and Environment.


  • Does insurance cover drug cleanup?

    It depends on your policy and the circumstances of the loss. Your insurer can confirm what applies to your property. We can document the damage, share cleanup records, and communicate with your adjuster.

  • How long does drug decontamination take?

    The timeline depends on how far the residue spread, which materials need to be removed, and whether the job requires lab testing or repairs. After the on-site assessment, we can outline the expected timeline and explain which steps may affect it.

  • Can landlords rent a unit again after drug use?

    Before renting the unit again, complete any needed cleanup and repairs and follow applicable reoccupancy requirements. Keep the written scope of work, cleanup records, and any required clearance results. 


    If meth contamination is suspected, ask a Colorado-certified consultant which assessment and clearance requirements apply to the unit.


  • What Is clearance testing?

    Clearance testing checks whether an affected area meets the applicable cleanup criteria after the work is complete. An independent environmental professional collects samples, often by wiping selected surfaces, and reviews the lab results to determine whether more cleaning is needed.
