Virus and COVID disinfection goes beyond wiping down surfaces. It involves a systematic, step-by-step process aimed at reducing the viral load in an indoor environment to a level that is safe for re-entry. The work begins with a thorough assessment of the affected area, identifying all high-touch surfaces such as doorknobs, light switches, countertops, remote controls, and bathroom fixtures. Every surface that may have been contaminated is treated, not just those that are visibly soiled. The process uses EPA-registered disinfectants that are specifically effective against enveloped viruses like SARS-CoV-2, applied according to the manufacturer’s dwell time — meaning the disinfectant must remain wet on the surface for a specified period to kill the virus. This is not a quick spray-and-wipe job; it requires careful timing and coverage. For Ontario properties — whether they are single-family homes, apartment units, or commercial spaces — the goal is to restore a healthy environment while minimizing disruption. The disinfection team wears appropriate personal protective equipment, including respirators, gloves, and gowns, to prevent cross-contamination and to protect themselves during the work. Soft surfaces like upholstery, carpets, and curtains may require specialized treatment, such as steam cleaning or fogging with a disinfectant mist. Electronic devices, which are often handled frequently, are cleaned with alcohol-based wipes that are safe for screens and keyboards. The entire process is documented, and the property is left ready for normal use after the disinfection is complete. This level of thoroughness matters because viruses can linger on surfaces for hours or days, and a missed spot can lead to reinfection. For Ontario residents and business owners, proper disinfection means peace of mind that the space is truly clean. ## Areas We Cover in Ontario We provide virus and COVID disinfection services throughout Ontario and its surrounding neighborhoods.
