How is this different from an air freshener or getting the carpets cleaned?

Air fresheners and surface cleaning mask or partly reduce a smell, but the odor molecules behind it usually stay in porous materials and the air, so the smell comes back. We find the actual source, often the subfloor, ductwork, or inside cabinets, then neutralize those molecules with the right green, non-toxic tool for the job, like enzymatic and oxidizing treatment for urine, thermal fogging for smoke, hydroxyl generators for occupied rooms, and carbon scrubbing for the air. That's why the result is permanent instead of temporary.

Is the treatment safe for my kids, pets, and electronics?

Yes. We use eco-friendly, non-toxic treatments chosen to be safe around children, pets, and electronics, and we're fully insured. We don't use ozone or chlorine gas, because ozone is a respiratory irritant and chlorine is harsh and risky. Instead we rely on people-safe options like hydroxyl generators and air scrubbing, along with source removal, enzymatic treatments, and thermal fogging, and we'll explain exactly what's running during your visit.

How quickly can you come out, and how long does it take?

We offer same-day and next-day appointments, and many jobs are finished in one to four hours. The exact time depends on how strong the odor is and how deeply it has set in, so a cooking smell clears fast while heavy smoke saturation can take longer or a second pass. We'll give you an honest assessment, including whether anything needs replacing rather than treating, before we start.

Why Choose Odor Removal Experts? Our Guaranteed, Green Process

Cost & Methods · By Odor Removal Experts · Updated June 2026 · Cleveland and Northeast Ohio

A bad smell is rarely just annoying. It can drag down a home's sale price, kill a used-car deal, or get an Airbnb listing pulled. The problem with most quick fixes is that they don't fix anything. Air fresheners, scented candles, and a carpet shampoo cover the smell for a few hours or a few days, but the source is still sitting there at the molecular level. Once the masking fades, the odor is right back.

That is where odor removal done properly looks completely different. Odor Removal Experts permanently eliminate odors at the source instead of perfuming over them, and we do it with green, non-toxic methods, never ozone or chlorine. We back the result with a 100% guarantee. This guide walks through what we actually do on a job, which method fits which smell, and why people across Greater Cleveland and Northeast Ohio bring us in when they need the smell gone for good.

The short answer

Odor Removal Experts remove smells permanently at the source instead of masking them, using green, non-toxic methods and never ozone or chlorine. We find where the odor is trapped, match the right treatment to the material, and back every job with a 100% guarantee. Most jobs finish in one to four hours, with same-day or next-day service across Cleveland and Northeast Ohio.

Permanent odor removal, not a cover-up

Odors are physical. They come from real molecules that cling to surfaces, soak into porous materials, and float in the air. As long as those molecules are present, the smell returns no matter how much fragrance you spray over it. Everything we do is built around finding and neutralizing them, not hiding them.

On most jobs, the smell is worse than it looks. The spot people miss is almost always behind or underneath something. With pet urine it's cat urine soaked into the subfloor, not just the carpet you can see. With smoke it's the inside of cabinets, the top of door frames, and smoke smell in the HVAC ducts the air pulled it through. We find the source first, because treating the air without treating the source just buys you a few clean-smelling days.

The right method depends on the odor and the material it's living in. We don't use one blanket fix, and we never reach for ozone or chlorine gas. For protein-based smells like urine and decay, enzymatic and oxidizing treatments break the compounds down so they can't keep off-gassing. For smoke that traveled through a space, thermal fogging is the workhorse, because the fog follows the exact same paths the smoke did and reaches the cracks a sprayer can't. Hydroxyl generators are our go-to because they're safe to run in rooms people are still using. HEPA and activated-carbon scrubbing pulls particulate and gas out of the air, and when a material is too saturated to save, we'll tell you straight that removal or sealing is the honest answer.

Green and safe around people, pets, and electronics

Solving one problem shouldn't create another. We use eco-friendly, non-toxic treatments chosen to be safe around children, pets, and sensitive electronics. You shouldn't have to trade a healthy room for a clean-smelling one.

No ozone or chlorine, ever

Ozone is a respiratory irritant and chlorine is harsh and risky, and neither fits how we work. Instead we rely on people-safe options like hydroxyl generators and activated-carbon scrubbing, which can run while life goes on, alongside source removal, enzymatic and oxidizing treatments, thermal fogging, and sealing.

Whatever's running, we'll tell you what it is and what, if anything, you need to do during the visit. And because we're fully insured, you're covered before we ever start.

Fast results and same or next-day service

Most odor problems are urgent. A buyer is coming to look at the car, a guest checks in tomorrow, or you just can't take it another night. Many of our jobs wrap in one to four hours, and we offer same-day or next-day appointments so you're not waiting a week with the windows open.

How long it takes depends on how strong the odor is and how deep it has set in. A lingering cooking smell clears fast. Years of heavy smoke saturation soaked into drywall and framing takes longer and sometimes more than one pass. When we're on site we'll give you a straight read on what to expect, including whether anything needs to be replaced rather than treated, instead of selling you an inflated promise.

What you can try yourself, and when to bring in a pro

Plenty of small smells are worth a DIY shot first. There's no reason to pay anyone for these:

Fresh spills cleaned up right away
A fridge freshened with baking soda
A load of laundry for smoky fabrics
Good ventilation to air out everyday odors

The store-bought ozone mistake

A common mistake we get brought in to fix is a store-bought ozone machine run by someone who didn't seal or ventilate the space, which can damage materials and leave the smell anyway. That's exactly why we don't touch ozone and stick to green, non-toxic methods.

Bring in a pro when the smell keeps coming back after you clean, when it has soaked into carpet padding, subfloor, drywall, or upholstery, or when it's smoke, biological, or a mystery you can't trace. If you've cleaned twice and it's still there, the source is deeper than the surface, and that's our cue.

Backed by a 100% guarantee

The standard is simple. If it's not gone, we're not done. We back every job with a 100% guarantee on odor elimination, and the only reason we can stand behind that is because we treat the source instead of masking it. If an odor isn't fully resolved, we come back and finish the work.

To be straight with you, this guarantee covers odor removal, not health outcomes, and we don't make medical claims. We focus on what we can actually deliver, which is a space that smells clean because the odor-causing molecules are gone, achieved with green, non-toxic methods and never a cover-up. We also won't promise an exact price sight unseen. Cost depends on the size of the space, the type of odor, and how deep it has set, and we'll give you the factors plainly before any work starts.

Every property type, Cleveland and Northeast Ohio

We handle a lot more than houses. Our technicians work on used and personal vehicles, yachts, private jets, apartments and condos, offices and commercial spaces, hotels, and short-term rentals. Each one has its own materials and airflow, and a sealed car cabin gets treated very differently from an open office, so we adjust the approach to fit.

We serve Greater Cleveland and Northeast Ohio. Our technicians are fully insured, show up in uniform, and work discreetly, which matters when the visit is to a private home, a guest-facing business, or a vehicle you're about to sell.
