Deep sanitizing and disinfection is usually the step that happens after the bulk of a hoard has been cleared out. Removing furniture, trash, and clutter gets a space empty, but it doesn't deal with what's left behind: mold on baseboards, pest droppings, urine or feces from animals, bodily fluids, or months of trapped odor soaked into drywall, subflooring, and insulation. This service targets those hazards directly, using hospital-grade or EPA-registered disinfectants, enzyme treatments for odor at the source, HEPA-filtered air scrubbers, and sometimes ozone or fogging equipment for spaces that need a full atmospheric treatment.
We're tracking 14 companies in Ottawa that offer this work, and the gap between the best and the rest is significant. Some crews show up with all-purpose cleaner and a mop. Others come with biohazard training, proper PPE, and a documented process for testing air quality and surfaces before they call a job finished.
When you're comparing providers, ask about their disinfectant products (look for EPA/Health Canada-registered options, not generic store-bought sprays), whether they handle odor removal as a separate specialized step, if they carry biohazard or trauma cleanup certification, and whether they document the work with before-and-after photos. Our scoring weighs these factors along with response time, licensing, and verified customer feedback, so you're not left guessing from a company's own marketing copy.
