Proven Leaders in Drug Cleanup & Biohazard Remediation for Over Two Decades
Certified Forensic Operator David Hart, Founder and Owner of Guarantee Biohazard Remediation, has spent more than two decades advancing safe, effective methods for illicit drug residue and chemical decontamination. His work helped shape many of the standards used in the industry today.
Guarantee Biohazard Remediation continues that legacy by delivering precise, fully documented decontamination for properties impacted by illicit drugs, chemical contamination, tear gas, and environmental hazards — restoring spaces with measurable, defensible results.
For Conditions That Demand More Than “Clean”
Our specialized team and equipment ensure every cleanup is performed to the highest safety standards. We coordinate closely with all relevant authorities to guarantee full compliance with required safety protocols at every stage of the process.
Defining Industry Standards in Forensic Restoration
Our remediation process is built on forensic science and contamination‑specific analysis, backed by decades of field experience. We determine the true scope of illicit drug and chemical residue, apply precisely targeted decontamination protocols, and document every stage with defensible clarity. The result isn’t a space that simply meets minimum thresholds, rather, an environment restored as close as possible to its pre‑contamination condition through verified, technically exacting methods.
