Smoke. Pets. Urine. Fire. Gone In 24 Hours.
A tenant who smoked for ten years. A dog that lived on the carpet. A small kitchen fire. A unit that sat closed for a summer. Paint and cleaning only hide those smells for a few weeks. We seal the space and treat it with a professional ozone generator fed by an oxygen concentrator — the smell is oxidized out of the walls, floors and ceilings, not covered up. Most units are done in 24 hours; the worst cases take up to 3 days.
What We Remove
Every one of these has soaked into the materials of the room — drywall, paint, carpet, subfloor, closets, ducts. That is why cleaning, airing out and repainting bring it back the first warm week. Ozone reaches the same places the smell did.
The most common call. Years of smoking leave a yellow film on every surface and a smell inside the paint and the drywall itself. Washing the walls helps; painting helps for a while; ozone is what actually ends it. Do it before the new paint goes on, not after.
Dog and cat odour, litter boxes, urine that has gone through the carpet into the underlay and the subfloor. Once the damaged flooring is out, ozone deals with what is left in the concrete, the baseboards and the walls, so the new floor does not pick the smell back up.
A pot left on the stove, a space heater, a balcony fire next door. Once the restoration cleaning is done, the smoke smell is still in everything the cleaners could not take out. Ozone treatment is the standard last step — and the one that decides whether the unit can be rented again.
Cooking grease, body odour, a unit that was never aired out, mould and mildew from a damp bathroom, a sewage backup that has been cleaned up but still announces itself. The turnover smell, in short. One treatment, and the next showing starts with a unit that smells like nothing at all.
Decomposition odour after a death in a unit, long-term hoarding, heavy animal contamination. These are the jobs where we treat for up to three days with the space sealed, with ventilation and re-treatment between cycles. They are difficult, they are not pleasant, and they are exactly the cases ozone was made for.
The same equipment handles a work van that smells of fuel and cigarettes, a basement with a musty smell that has outlasted the dehumidifier, a storage room, a restaurant back-of-house after a grease problem. If it has a door that closes, it can be treated.
How It Works
Ozone is O3 — oxygen with a third atom that it badly wants to give away. It gives it to the molecules that cause the smell, oxidizing them into something that does not smell, and then turns back into the ordinary O2 you breathe. It is the same chemistry that makes the air smell clean after a thunderstorm, done on purpose and at strength.
Ozone handles what has soaked in; it does not handle a full litter box or a wet underlay. We look at the unit first, tell you what has to come out before treatment — sometimes nothing, sometimes a carpet — and give you one fixed price for the job.
Doors closed, vents and gaps taped, closets and cabinets open so the ozone reaches inside them, and a warning sign on the door. Nobody — no people, no pets, no plants — is inside for the whole treatment. This is the part that matters, and it is why this is not a machine to rent and run yourself.
A consumer ozone machine makes ozone from room air and produces a small amount. Ours runs on a medical-grade oxygen concentrator, so it generates several times the concentration and keeps it up for hours. That is the difference between a treatment that takes a day and one that is still not finished after a week.
When the cycle is done we open the unit up, run the air through, and check that the ozone has broken back down before anyone goes in. You walk in and smell nothing — which, on a turnover, is the whole point.
For Landlords & Property Managers
A unit that smells of the last tenant shows badly, rents slowly, and gets the first complaint from the new tenant before the ink is dry. One day of ozone between the move-out and the paint changes all three.
Paint over a smoker’s unit and the smell comes through the new coat by summer. Treat first and the paint seals a clean wall. Same money for the paint; completely different result.
The treatment runs while the unit is already empty and already being worked on. On a renovation turnover it costs no calendar days at all — we run it overnight between trades.
“The unit smelled of smoke when I moved in” is a complaint that turns into a rent-reduction request. A treated unit removes the argument before it starts, and the invoice documents that it was done.
Garbage rooms, stairwells, a hallway after a sewer backup, the laundry room, a locker area with a musty smell. Same treatment, scheduled overnight so residents are not inconvenienced.
Already a client? Ask for ozone to be added to the next turnover or renovation quote — it is a line item, not a separate visit. New to us? Here is what we do for buildings, or request a quote.
Transparent Pricing
No hidden fees — you'll always know the cost before we start.
Covers travel to your door and the first hour of labour.
Billed per additional hour beyond the first, in clear increments. The rate is per technician — if a job needs two of us, we tell you before we start.
Clearing the main sewer line of a single-family home with an accessible cleanout.
Half price when added to the same visit — there is no second trip to pay for. You keep the recorded video and a written condition report.
Drain prices are for a single-family home with an accessible cleanout, with the camera run from the house to the property line. Priced separately: access through a pulled toilet or roof vent when there is no cleanout, sonde locating of the line, and any excavation.
Larger jobs — renovations, installs, backwater valves, sump pumps — are quoted as a fixed price upfront after a quick assessment, not billed hourly. Request a free estimate. Inspections are different: camera work, leak detection and pre-purchase reports are billed at the rates above, because what you get is the findings and the footage, not a quote. If you go ahead with the repair, the inspection fee comes off your invoice.
Questions
Ozone (O3) is an unstable form of oxygen. Our generator, fed by an oxygen concentrator, fills the sealed space with it; the ozone oxidizes the molecules that cause the smell — in the air, in fabrics, in drywall and in flooring — and then breaks back down into ordinary oxygen. Nothing is masked and nothing is left behind.
Most apartments and houses — smoke, pets, cooking, a tenant who smoked for years — are done within 24 hours including ventilation. Severe cases such as fire smoke or decomposition odour can take up to 3 days of treatment.
Yes, when it is done by someone who knows the equipment. The space must be empty — no people, pets or plants — for the whole treatment, it is sealed and posted, and afterwards we ventilate it and check the air before anyone goes back in. You should not run a rented ozone machine in an occupied home.
Cigarette and cannabis smoke, pet odour and urine, cooking and grease, mould and mildew smell, sewage backup odour, smoke after a small fire, and decomposition odour. It works on the whole room at once — walls, floors, ceilings, closets and ductwork — not just the air.
Yes — it is the most common job we do it for. Years of smoking soak into paint, drywall and carpet; painting over it only holds the smell back for a few months. Ozone oxidizes the residue in the materials themselves. Done before the new paint, it is the difference between a turnover that smells new and one that gets a complaint in the first warm week.
A fixed price per unit, quoted upfront after a quick look at the space and the source of the smell. For landlords and property managers it is usually bundled with the turnover or renovation we are already doing, which keeps the cost down because the unit is already empty. Request a quote.

About Us
Ankor Ltd. has been working across Toronto since 2013. The company started when our founder left the firm he worked for and the residential buildings he had been maintaining asked him to keep looking after them — which is why a family-sized crew ended up servicing apartment buildings alongside houses. In Toronto that mix is exactly right: the same week can take us from a century home on the Danforth to a mechanical room downtown.
It is still a family business. Calls are answered by our office rather than a call centre, the plumber who quotes the job is the one who does it, and the price is agreed before anything is opened up. Every plumber is licensed and insured, we carry WSIB coverage, and we take out the permits and meet the inspectors on the work that needs them.
