Deep sanitizing and disinfection is the stage of a hoarding cleanup that comes after the bulk removal of clutter, debris, and unsalvageable belongings. Once floors and surfaces are exposed, crews treat the space for biohazards, mold, pest residue, odor-causing bacteria, and other contamination that builds up in a home over months or years of heavy clutter. This can include enzymatic cleaning, HEPA vacuuming, hard surface disinfection, deodorizing treatments (ozone or thermal fogging), and sometimes limited mold remediation before a home is safe to occupy, sell, or hand back to a landlord. There are 5 businesses offering this service in Mississauga, and the difference between a mediocre job and a thorough one usually comes down to process and equipment, not just price.
When comparing providers, ask what disinfectants they use and whether they're hospital-grade or EPA/Health Canada registered, whether they test for odor and biological hazards after treatment (not just by smell), and whether they carry insurance for biohazard work. Crews that document their process with photos and give a written scope tend to deliver more consistent results than those quoting a flat number over the phone.
Our ranking weighs licensing, equipment, documented process, and how each company handles the sanitizing step specifically, not just the haul-away work.
