Professional biohazard cleanup goes well beyond standard cleaning. It includes scene assessment and containment, removal of all biohazardous material using proper PPE, deep decontamination with EPA-approved hospital-grade disinfectants, complete odor elimination, and structural restoration if flooring, drywall, or subfloor needs to be removed. All biohazardous waste is disposed of through a licensed facility in compliance with OSHA and Illinois state regulations. McMahon Services handles the entire process in-house, from first call to final clearance.

In many cases, yes. Biohazard cleanup is often covered under a homeowners, condo, or commercial property policy, depending on the specifics of the incident. McMahon Services is a preferred contractor with major carriers including Allstate, Travelers, Liberty Mutual, Farmers, and USAA. We coordinate directly with your adjuster and handle the required documentation, so you’re not managing paperwork on top of an already difficult situation.

Timeline depends on the size of the affected area, the type of biohazard, and whether structural materials need to be removed and replaced. A single contained room can often be fully remediated within a few hours. Larger or more complex jobs — an undiscovered death, extensive sewage contamination, or damage across multiple rooms or a shared condo hallway — can take one to several days. McMahon Services gives you a clear, honest timeline at the initial visit, so you know what to expect before work begins.

No — occupants should not be inside a property during active biohazard remediation. McMahon Services sets up containment zones and uses equipment and chemical agents that require the space to be vacated while the work is underway. We move efficiently to complete the job so the property can be safely re-occupied, and we provide clearance documentation once the scene has been fully decontaminated and verified safe.

Standard cleaning addresses visible dirt and surface debris. Biohazard cleanup is a regulated, specialized process that deals with bloodborne pathogens, bodily fluids, and other biological hazards — many of which aren’t visible at all. It requires OSHA-trained technicians, EPA-approved disinfectants, full PPE, and licensed disposal of all biohazardous waste. Attempting a biohazard scene without the right training and equipment puts anyone involved at real risk of exposure to infectious disease.

Yes — once McMahon Services has completed remediation and confirmed the area is safe, occupants can return. We provide documentation verifying the property has been properly decontaminated, which also serves as a legal record for Palatine landlords, condo boards, and property managers. Our goal is always to get the property back to safe, habitable condition as quickly as possible, so families and tenants aren’t displaced longer than necessary.

McMahon Services handles the full range of biohazard scenarios in Palatine — unattended and undiscovered deaths, trauma and crime scene cleanup, suicide remediation, sewage and black water contamination, hoarding situations, infectious disease decontamination, and workplace or accident scenes. Palatine’s mix of single-family neighborhoods, condo and townhome associations near downtown and the Metra line, and commercial properties along Rand Road and Northwest Highway means these calls come from a wide range of property types. Our team responds around the clock with the discretion every situation requires.

Yes — rental and condo biohazard calls are common in Palatine given how many multi-unit buildings and townhome communities sit near downtown and the Harper College area. When a resident passes away unexpectedly or a unit is left in a biohazardous condition, landlords and condo boards face both a health hazard and a legal obligation to remediate before the space can be re-occupied. McMahon Services responds immediately, documents all work thoroughly for insurance and legal purposes, and restores the unit or common area to safe, habitable condition as quickly as possible — so you can meet your obligations and limit vacancy time.
