Every smoke situation is different. A home where someone smoked indoors for a decade is a different job than a kitchen fire or a vehicle with lingering cigarette smell. The type of smoke matters too. Cigarette and cigar smoke leave behind tar and nicotine residue that bonds to surfaces over time. Fire smoke contains soot and combustion byproducts that penetrate insulation, framing, and HVAC systems differently than tobacco smoke. Marijuana smoke tends to be less persistent but still embeds in carpet, fabric, and soft surfaces.
The treatment plan, prep work, and number of sessions all depend on the severity and how deeply the smoke has penetrated. A single room with light exposure might need one treatment. A whole-house cigarette smoke situation where someone smoked indoors for years may need multiple sessions with surface prep in between. We'll be upfront about what your situation actually requires so you know exactly what you're getting into before we start.
Common Smoke Odor Situations We Handle
We regularly treat homes where tenants or previous owners smoked indoors for years, rental properties that need smoke odor eliminated before the next tenant, houses with fire or kitchen smoke damage after restoration is complete, vehicles purchased from smokers or at auction, and estate or inherited homes being prepared for sale where cigarette smell is keeping buyers away.
What Happens After You Submit
We'll reach out by phone or email, usually within a few hours, to ask a few follow-up questions about the space and the smoke exposure. From there, we'll give you a clear estimate with no hidden fees and schedule your treatment. Most smoke odor removal jobs can be scheduled within 24 to 48 hours.

Cigarette and Tobacco Smoke Removal
Years of cigarette or cigar smoking leaves tar and nicotine residue embedded in drywall, ceiling texture, carpet, padding, HVAC ductwork, and subfloor. This residue bonds to surfaces and continues to off-gas odor long after the smoking stops. Surface cleaning, fresh paint, and air fresheners don't reach it. Our ozone treatment penetrates every surface in the space, breaking down tar and nicotine compounds at the molecular level. For homes with heavy long-term smoking, we may recommend sealing or priming walls and ceilings before treatment, followed by one or more ozone sessions for full elimination.
Marijuana Smoke Odor Removal
Marijuana smoke is less persistent than cigarette smoke but still embeds in carpet, upholstery, curtains, and soft surfaces. In rental properties and apartments, marijuana odor is one of the most common complaints from new tenants and property managers. Ozone treatment eliminates marijuana smoke odor without the need for deep surface remediation in most cases. A single treatment is usually sufficient for light to moderate exposure. For grow house situations or heavy long-term use, multiple sessions may be needed.
Cooking and Food Smoke Odor Removal
Grease fires, burnt food, heavy oil cooking, and years of kitchen smoke leave odors that ventilation alone can't clear. The smell settles into cabinets, walls, ceiling texture, and flooring around the kitchen and spreads into adjacent rooms over time. This is especially common in multi-unit buildings, rental properties, and homes where heavy frying or charring was routine. Our ozone treatment reaches every surface the smoke reached, including inside cabinets and behind appliances. For kitchens with heavy grease buildup on surfaces, we recommend a thorough degreasing and cleaning before treatment so the ozone can work on the embedded odor rather than surface residue.
Rental and Apartment Smoke Odor Removal
Turning over a rental unit where a tenant smoked indoors is one of the most common calls we get from landlords and property managers across St. Louis. The smell keeps new tenants away, triggers complaints, and can reduce what you can charge in rent. Our set-and-leave ozone treatment is built for this situation. We place the equipment, seal the unit, and the treatment runs while the property is vacant. Most apartment and rental treatments can be completed in a single session with next-day turnaround, getting your unit back on the market fast.
Vehicle Smoke Odor Removal
Cigarette smoke in cars, trucks, SUVs, and RVs embeds in seat foam, headliner fabric, carpet, and the HVAC system. Detailing and air fresheners can reduce the smell temporarily, but the odor returns because the source is still trapped in the materials. We place our ozone generator inside the sealed vehicle and run it for several hours, reaching every surface, vent, and cavity that the smoke reached. This service is popular with car dealerships, used car buyers, and anyone who purchased a vehicle with an existing smoke smell.
Fire and Smoke Damage Odor Removal
House fires, kitchen fires, and electrical fires leave behind soot and combustion byproducts that penetrate walls, insulation, HVAC systems, and structural framing. Even after fire restoration crews remove the damaged materials and clean the surfaces, the burnt smell often lingers for months. Our ozone treatment is designed to be the final step after restoration work is complete. Once damaged materials are removed and surfaces are cleaned, we treat the entire space to eliminate the smoke odor that restoration alone can't reach. If your restoration company finished the job but the smell is still there, that's exactly when to call us.
Why Smoke Odor Is So Hard to Remove
Most people try air fresheners, candles, baking soda, vinegar, or odor-neutralizing sprays first. Some repaint. Some shampoo the carpets. The smell comes back every time, and here's why.
Smoke particles are microscopic. When someone smokes indoors or a fire occurs, those particles travel through the entire space and settle into every porous surface they contact. Drywall absorbs them. Ceiling texture traps them. Carpet fibers and padding hold them. Smoke enters HVAC ductwork and circulates through the system, depositing residue on every surface the air touches. Over time, tar and nicotine compounds bond chemically to these materials.
Surface cleaning only reaches what you can see and touch. The smoke odor isn't coming from the surface. It's coming from inside the walls, inside the carpet pad, inside the ducts, and inside the subfloor. That's why the smell comes back after painting, cleaning, or airing out the space. You're treating the symptom while the source stays embedded in the structure.
This is why professional ozone treatment works when nothing else does. Ozone is a gas. It fills the entire space the same way smoke did, reaching into walls, carpet fibers, ductwork, and every crack and crevice that surface treatments can't touch. Instead of masking the odor, ozone breaks down the compounds causing it at the molecular level. Once those compounds are destroyed, the smell is gone permanently.
How Much Does Smoke Odor Removal Cost?
The cost of professional smoke odor removal depends on three factors: the size of the space, the type of smoke, and how long the exposure lasted.
Most residential smoke odor treatments in the St. Louis area run between $200 and $500 for a standard home. Vehicles typically cost less. Severe cases like whole-house cigarette smoke from years of indoor smoking or significant fire damage may require multiple treatments, which increases the total cost.
Here's what affects your price:
Size of the space. A single room or vehicle costs less than a full house treatment. Larger homes with multiple levels and finished basements require more ozone output and longer treatment times.
Type and severity of smoke. Light marijuana smoke in an apartment is a quicker job than a home where someone smoked two packs a day for 15 years. Fire smoke with soot damage requires more preparation and may need multiple sessions.

FAQs

Can smoke smell be permanently removed from a house?
Yes, but only if the source is properly addressed. Ozone destroys the tar, nicotine, and combustion compounds that cause smoke odor at the molecular level. Once those compounds are eliminated, the smell is gone for good. However, if smoke-damaged materials like saturated carpet pad, contaminated insulation, or heavily stained drywall aren't removed or sealed before treatment, the odor can persist. That's why we assess the space before every job and tell you exactly what prep work needs to happen first. When the source is handled and the ozone treatment is complete, the results are permanent.
How many ozone treatments does it take to remove cigarette smoke?
It depends on the severity. A home with light to moderate smoke exposure typically needs one treatment. Heavy smoker homes where someone smoked indoors daily for years may require two or three sessions with surface prep in between. We'll give you an honest assessment during your free estimate. We'd rather tell you upfront that it's a multi-session job than have you disappointed after a single treatment.
Does ozone remove smoke smell from a car?
Yes. We place the ozone generator inside the sealed vehicle and run it for several hours. The ozone reaches seat foam, headliner fabric, carpet, and the HVAC system, all the places smoke particles embed that detailing can't reach. One treatment is typically enough for moderate smoke exposure. Heavy smoker vehicles may need a second session.
How long does a smoke odor removal treatment take?
Most residential treatments run between 8 and 10 hours depending on the size of the space and severity of the smoke. Vehicle treatments are typically 2 to 4 hours. The space must be unoccupied during treatment, including pets and plants. After treatment, the ozone converts back to regular oxygen within 30 to 60 minutes, and the space is safe to re-enter.
Is ozone treatment safe after the smoke smell is removed?
Yes. During treatment, the space must be completely unoccupied. No people, pets, or plants. Once the machine is turned off, the ozone converts back to regular oxygen within 30 to 60 minutes. There are no chemicals sprayed on surfaces, no residue left behind, and nothing toxic remaining in the space. We'll tell you exactly when it's safe to return.
How do I remove smoke smell from my house before selling?
If you're preparing a home for sale, odor removal should be one of the last steps before listing. First, address the physical sources: remove or replace contaminated carpet and pad, prime or seal smoke-stained walls and ceilings, and have the HVAC ducts cleaned. Once that prep work is done, schedule an ozone treatment to eliminate any remaining smoke odor from the air and surfaces. As a licensed St. Louis real estate agent, Kyle Weindel built this business specifically for this situation. We work directly with listing agents, sellers, and investors to get homes market-ready fast.
