How much does deep sanitizing after a hoarding cleanup cost in Ottawa?

It depends heavily on square footage and contamination level. A single contaminated room with odor treatment might run a few hundred dollars, while a full-house job involving mold remediation, subfloor treatment, and biohazard disposal can run into the thousands. Most companies quote after an in-person or photo-based assessment rather than a flat rate, since the amount of organic waste and material affected varies so much case to case.

Is deep sanitizing a one-time treatment or does it need to be repeated?

For most hoarding situations, a thorough sanitizing pass after the bulk cleanout is meant to be a one-time fix, provided the underlying moisture, pest, or clutter issue doesn't return. If mold was extensive or the home sat in poor conditions for years, some companies recommend a follow-up inspection a few weeks later to confirm odor and mold haven't come back before floors or walls are resealed.

What should I expect the crew to actually do on-site?

Expect them to remove remaining debris and soiled materials first, then apply enzymatic or antimicrobial treatments to affected surfaces, run air scrubbers or HEPA filtration, and disinfect hard surfaces last. Porous materials like carpet, drywall, or subflooring that are too contaminated to treat are usually flagged for removal rather than just sprayed over.

How can I tell if a company did a good job?

A clean sanitizing job should leave no lingering odor once the space has aired out, and any mold-affected material should have been removed rather than painted over or masked with fragrance. Ask for before-and-after documentation and, for serious mold or biohazard cases, a clearance check. If a company can't describe what product they used or why, that's a red flag.

Deep Sanitizing & Disinfection in Ottawa

Deep Sanitizing & Disinfection in Ontario

Deep sanitizing and disinfection is usually the last stage of a hoarding cleanup, after bulk debris and belongings have been sorted and removed. It covers what the removal crew leaves behind: surfaces contaminated by mold, pest activity, rodent droppings, biohazards, or months of trapped odor. In Ottawa, the 7 companies working in this space handle jobs ranging from a single bedroom that needs an odor treatment to a full home requiring subfloor sanitizing after severe animal or pest infestation.

The actual work can include enzymatic cleaning to break down organic waste and urine, HEPA vacuuming and air scrubbing to pull allergens and mold spores out of the air, hospital-grade disinfectant application on floors and walls, and in some cases ozone or thermal fogging to neutralize smoke or decomposition odor. It is a different skill set from general junk removal, and not every hauling company does it well.

When comparing providers, ask what disinfectant products they use, whether they test for mold or just spray over it, whether they carry biohazard handling training, and how they document the job (before/after photos, air quality readings). A company that can explain its process step by step is usually more reliable than one that just quotes a flat price over the phone.
