The real problem
Why the smell keeps coming back
You tried sprays, little trees, maybe a shampoo. A few days later the smell was back, because it was never just on the surface.

Seat foam
The smell soaks into the foam under the fabric or leather.
Headliner
The roof lining holds smoke like a sponge.
Carpet and padding
Trapped deep, where a vacuum can’t reach.
A/C and vents
The smell recirculates every time the fan runs.
It’s always worse on a hot day, or in the morning after the car sat closed all night: heat pushes the trapped smell back out. Until it’s treated at the source, it keeps coming back.
How it works
We treat the source, not just the air
A fragrance covers a smell for a few days. We find where it comes from, clean what holds it, then treat the air and the fabric.
Is ozone alone enough?
For a light, recent smell, often yes. Soaked-in smoke also lives in the foam, the headliner and the A/C, and ozone alone won’t clear it. That’s why a full restoration cleans the source first.

01 Diagnosis
- We find the source: smoke, pets, mould or the A/C
- We check how deep the smell goes
- The option and the price are confirmed before we start
02 Clean the source
Full restoration
- Deep cleaning of what absorbed the smell: seats, carpets, headliner
- Only the affected surfaces, based on the diagnosis
- Cabin filter replaced if needed
03 Treat the air and fabric
- Ozone treatment in the closed, empty car
- Air-system and vent treatment
- Odour neutralization on restorations
04 Air out and check
- About an hour of airing out before pickup
- We check the result before handing the car back
- An extra cycle if needed
Used car
Just bought a used car that smells like smoke?
We see it often: the smell didn’t show on the test drive, then it comes back with the heat or the fan. Two of the reviews below tell exactly that story.
- Smoke that has soaked in for years needs a full restoration: we clean what holds the smell, then treat the air and the fabric.
- The diagnosis tells you what your car needs before we start.
- The 60-day odour guarantee applies, as long as nobody smokes or vapes in the car.
- Bought it from a dealer? After the diagnosis, you get an itemized invoice with our findings to show the dealer. Some of our clients have had the cost covered that way.

“Amazing service! We bought a new to us used vehicle, only to find out previous owner had smoked in the vehicle. The smoke smell wasn’t apparent at first from the dealer and we liked the vehicle much, didn’t want to get rid of it. So, I reached out to Psycho Detailing, they tackled the job to rid of the smoke smell throughout the inside..deep cleaned leather, thoroughly washed the headliner […] the works! Immediately the difference was day and night!!”

The final price is confirmed at the diagnosis, before any work. The service is done only at the Terrebonne studio, for clients from Terrebonne, Laval, Montreal and the North Shore.
Smoke and odour removal: frequently asked questions
The questions clients from Montreal, Laval and the North Shore ask us most.
Ozone odour treatment starts at $179 for a light or recent smell. Full restoration, for soaked-in smoke or a deeper smell, starts at $449 and comes with the 60-day odour guarantee. The final price depends on the source and severity of the smell, how long it’s been there, the vehicle size and how far the contamination goes. We confirm it at the diagnosis, before we start. Taxes extra.
Ozone is a gas that oxidizes odour molecules in the air and fabric, so it neutralizes the smell instead of masking it. For a light, recent smell it’s often enough. Soaked-in smoke also lives in the seats, the headliner and the A/C, so ozone alone won’t clear it. Those cases need deep interior detailing of the affected surfaces and an air-system treatment, which is what a full restoration includes.
Yes. We treat the source of the smell instead of covering it with a fragrance. A light or recent smell often clears with an ozone treatment. Smoke that has soaked in over years needs a full restoration: we clean what absorbed the smell, then treat the air system and the cabin. It comes with the 60-day odour guarantee, as long as nobody smokes or vapes in the car again.
Often, yes. A smell comes back when it was masked or only treated on the surface: it stays in the foam, the headliner or the air system. At the diagnosis we find where it’s still trapped and explain why the first treatment didn’t hold. Those cars usually need a full restoration, with the 60-day odour guarantee; the price is confirmed at the diagnosis.
Ozone is a strong oxidizing gas: that’s what lets it break down odour molecules, and it’s why we only use it in the closed, empty car, at the studio. Nobody is in the car during the treatment. Afterwards, the car is aired out for about an hour before we hand it back. Our products are used according to the manufacturer’s directions.
Yes. Pet, urine and other organic smells are treated at the source: the affected fabric is deep-cleaned, then the cabin is treated. It’s different from smoke, so we assess it separately and adapt the treatment. If your car also has pet hair, see our pet hair removal.
A musty smell can come from the air system or from a water leak. For the air system, we treat it along with the vents and replace the cabin filter if needed. If it’s a leak, the leak has to be fixed first, or the smell comes back. We tell you at the diagnosis.
An ozone treatment is done the same day: plan for half a day at the studio, airing out included. Pickup time is confirmed at the diagnosis. A full restoration usually takes one day, up to two for difficult cases. A 20% deposit reserves your date. You get the timeline with your quote.
It comes with every full restoration. If the treated smell comes back within 60 days of pickup, we redo the treatment once at the studio, at no charge: message us within the 60 days and bring the car in. It doesn’t cover a smell that comes back because someone smokes or vapes in the car again, a new source of smell (pet, spill, food, water leak, mould) or a mechanical cause, such as a heater core or exhaust leak. The ozone treatment has no guarantee, but its price is deducted if you book a full restoration within 30 days.
For a light, recent smell, sometimes: airing the car out, cleaning the surfaces, washing the mats and changing the cabin filter can be enough. Smoke that has soaked in for months is in the foam, the headliner and the vents: sprays and little trees cover it for a few days, then it comes back. That’s where treating the source makes the difference.
Only at our climate-controlled studio in Terrebonne: odour removal isn’t offered as a mobile service. The work needs the studio’s equipment and a closed, controlled space.
