Professional Odor Removal in St. Louis
We eliminate smoke, pet, mold, musty, and vehicle odors using commercial-grade ozone technology. No sprays. No masking. No chemicals left behind. Just permanent results.
Tell Us What You're Dealing With
Every odor problem is different. Cigarette smoke in a rental property, pet urine in a home about to hit the market, a musty basement that won't air out, a used car that still smells like the last owner. The fix depends on the source, the severity, and the materials involved.
Some odors can be eliminated with a single ozone treatment. Others require source remediation first, like pulling contaminated carpet, sealing stained subfloor, or priming smoke-damaged drywall before we treat. We'll tell you exactly what needs to happen and in what order so you don't waste money on steps that won't solve the problem.
That's why we start every job with a free estimate. Tell us what odor you're dealing with, where it is, and how long it's been a problem. We'll let you know whether ozone treatment is the right solution, what prep work may need to happen before treatment, and what to expect on cost and timeline.
Most estimates are returned within a few hours. No pressure, no upselling, no unnecessary services. If ozone isn't the right fix for your situation, we'll tell you. If the source needs to be addressed before we can treat, we'll walk you through exactly what to do.
Common Situations We Handle
We regularly treat homes where tenants smoked indoors for years, rental properties with pet damage between tenants, estates and inherited homes being prepared for sale, vehicles purchased at auction or from private sellers, basements with persistent musty or mildew smells after water damage, and commercial spaces that need a fresh start between occupants.
If you're a real estate agent preparing a listing, a landlord turning over a unit, or a homeowner who has tried everything else and the smell won't go away, you're in the right place. We've handled hundreds of these situations across the St. Louis area since 2019.

Smoke Odor Removal
Cigarette, cigar, marijuana, and fire smoke are the most persistent odors we treat. Smoke particles are microscopic and embed in drywall, ceiling texture, carpet fibers, padding, HVAC ductwork, and subfloor over months or years of exposure. Surface cleaning, repainting, and air fresheners can't reach what's trapped in those materials.Our ozone treatment floods the entire space at 80,000 mg/h, breaking down tar and nicotine compounds at the molecular level. For heavy smoker homes or fire damage, we may recommend multiple treatments for full elimination. This is our most requested service and one of the most common reasons homes lose value or sit on the market.
Pet Odor Removal
Dog urine, cat urine, dander, and animal odors build up in carpet, padding, subfloor, baseboards, and furniture. The challenge with pet odor is that contamination sits beneath the surface. You can shampoo carpet repeatedly and still smell it because urine has soaked through to the pad or subfloor underneath.Before ozone treatment, contaminated materials need to be addressed: pulling saturated carpet and pad, sealing or replacing stained subfloor, or cleaning hard surfaces with an enzyme treatment. Once the physical source is handled, our ozone eliminates any remaining odor from the air and every surface in the space.
Mold and Musty Odor Removal
Musty smells in basements, crawl spaces, bathrooms, and water-damaged areas almost always point to a moisture problem. Mold and mildew produce volatile organic compounds that create that distinct damp, earthy smell. Until the moisture source is resolved and any mold remediation is complete, no odor treatment will fix it permanently.
Once the underlying issues are addressed, our ozone treatment eliminates the lingering musty odor from walls, carpet, wood framing, and furniture. If you've had mold remediation done but the space still smells, that's exactly when to call us. We handle the odor that remediation leaves behind.
Home Sale Odor Removal
Odor is the number one invisible deal-killer in real estate. Buyers form an opinion within seconds of walking through the front door. Smoke smell, pet odor, cooking odors, and musty basements cause price reductions, failed showings, and lost contracts. Staging and candles can't cover what's embedded in the structure of the home.
As a licensed St. Louis real estate agent, Kyle Weindel founded this business after watching odor kill two deals. Both homes were treated with ozone and sold the following weekend. We work directly with listing agents, sellers, and investors to get homes market-ready. Most jobs can be scheduled within 24 to 48 hours.
Car and Vehicle Odor Removal
Smoke, pet, mold, food, and spill odors in cars, trucks, SUVs, boats, and RVs are difficult to eliminate with detailing alone. Odor embeds in seat foam, headliners, carpet, and the HVAC system. Our ozone generator is placed inside the sealed vehicle and run for several hours, reaching every surface and vent that the odor reached.
This service is popular with car dealerships, used car buyers, and anyone who purchased a vehicle with an existing smell. One treatment typically handles the problem. For severe cases like heavy smoker vehicles, a second treatment may be recommended.
Fire Odor Removal
House fires, kitchen fires, and electrical fires leave behind smoke damage that goes far beyond what you can see. Soot and smoke residue penetrate walls, insulation, HVAC systems, and structural framing. Even after restoration work is complete, the burnt smell can linger for months if the air and porous surfaces aren't treated.
Our ozone treatment is used after fire restoration crews have finished their work. Once damaged materials are removed and surfaces are cleaned, we treat the space to eliminate the remaining smoke odor from the air, walls, and any materials that were kept. If your restoration company hasn't addressed the lingering smell, that's where we come in.
Our Story
We use the Bio3Blaster VH Tornado, a commercial-grade ozone generator with 80,000 mg/h verified ozone output and a 1,850 CFM industrial blower. This is restoration-contractor equipment, hand-built in Elyria, Ohio. It is significantly more powerful than the portable ozone machines sold online or used by general cleaning companies.
Our process is straightforward. We assess the space, advise on any source remediation that needs to happen first, then schedule the treatment. On treatment day, we place the equipment, seal the space, and let the ozone do the work. 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, leaving zero chemical residue.
We also work with property managers, landlords, and commercial property owners who need odor treatment for apartment turnovers, office spaces, and multi-unit buildings. Our set-and-leave process means minimal disruption. Most commercial jobs can be completed overnight or on weekends.
