Our Process, The McMahon Way
From the first call to the final clearance, McMahon Services handles every phase of biohazard remediation in Chicago — no gaps, no handoffs, no surprises:
- Rapid response and scene assessment — a certified technician arrives at your Chicago property within 30–60 minutes to evaluate the scope and contain the hazard immediately
- Containment and hazard control — we establish proper containment zones and deploy full PPE protocols before any remediation begins, protecting the surrounding property
- Biohazard removal and disposal — all biohazardous materials are safely removed and transported to a licensed disposal facility in full compliance with OSHA and Illinois regulations
- Deep decontamination and disinfection — we apply EPA-approved hospital-grade disinfectants throughout the affected area, eliminating bloodborne pathogens and harmful microorganisms at the source
- Odor elimination — specialized deodorization equipment removes biological odors completely, not just masking them
- Full structural restoration — if materials like drywall, flooring, or subfloor need to be removed and replaced, our in-house construction team handles it — returning the property to pre-incident condition

What does professional biohazard cleanup involve?
Will my insurance cover biohazard cleanup?
In many cases, yes. Biohazard cleanup is frequently covered under homeowners insurance or commercial property policies, depending on the circumstances of the incident. McMahon Services is a preferred contractor with major insurance carriers including Allstate, Travelers, Liberty Mutual, Farmers, and USAA. We work directly with your adjuster, handle all required documentation, and manage the claims process on your behalf — so you’re not navigating paperwork during an already difficult situation.
How long does biohazard remediation typically take?
The timeline depends on the size of the affected area, the type of biohazard, and whether any structural materials need to be removed and replaced. A contained scene in a single room may be fully remediated within a few hours. Larger or more complex situations — such as an undiscovered death, extensive sewage contamination, or multi-room affected areas — can take one to several days. McMahon Services provides a clear assessment and realistic timeline from the initial visit so you always know what to expect.
Is it safe to be inside the property during biohazard cleanup?
No — it is not safe for occupants to be inside a property during active biohazard remediation. McMahon Services establishes containment zones and uses specialized equipment and chemical agents that require the area to be vacated during the process. We work as quickly as possible to complete the remediation so the property can be safely re-occupied, and we provide clearance documentation once the scene has been fully decontaminated and verified safe.
