How much can odor lower my home's value?

Quite a lot for smoke. A 2013 Pfizer Canada survey of Ontario agents found indoor smoking can cut resale value by up to 29 percent, and the Thirdhand Smoke Resource Center reports lingering tobacco residue can lower value by as much as 30 percent, roughly 150,000 dollars on a 500,000 dollar home. One agent estimated pet history can drop value by around 30,000 dollars.

Will an air freshener or candle be enough to sell my home?

No. Fresheners and candles only add a scent on top of the old one, and buyers notice the mix. A strong floral smell at the door often reads as a cover-up and raises suspicion. The odor has to be removed at the source. We treat the cause and never mask it, so the home smells clean rather than perfumed.

How fast can you treat a home before a showing?

Most jobs are gone in 1 to 4 hours, and we offer same or next-day scheduling, so we can usually fit the work in before your listing goes live or before a weekend of showings. We are fully insured and back every job with a 100 percent guarantee. If the smell is not gone, we are not done.

Does Odor Removal Increase a Home's Sale Price and Speed?

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

Does odor removal increase home value? In most cases, yes. A clean-smelling home tends to sell faster and hold its asking price, while a lingering smoke or pet smell pushes buyers away and invites lowball offers. Real estate agents and home stagers repeat the adage, if I can smell it, I cannot sell it. The smell is often the first thing a buyer reacts to, before they ever look at the kitchen or the yard.

Buyers form an impression within the first few minutes of a showing. A bad smell makes them assume hidden problems, even when the home is sound. That assumption shows up as a lower offer, a longer time on the market, or no offer at all. If you are listing a home in Greater Cleveland, Akron, Canton, Mansfield, Youngstown, or Northeast Ohio, removing the odor at the source is one of the cheaper moves you can make before you list.

The short answer

Yes. A clean-smelling home sells faster and holds its asking price, while lingering smoke or pet odor invites lowball offers and a longer time on the market. Indoor smoking can cut resale value by up to 29 percent, and pet history can drop it by around 30,000 dollars. Removing the odor at the source before you list is a cheap move that protects both price and timeline.

Does odor removal increase home value, and by how much

The numbers around tobacco smoke are the clearest of any odor, and speed of sale suffers alongside price. On a 500,000 dollar home, a 30 percent hit is roughly 150,000 dollars.

More than half of agents say buyers are much less likely to consider a smoked-in home
Pet history can drop value by around 30,000 dollars, by one agent's estimate

The pet figure is one agent's estimate rather than a hard market study, but it lines up with what stagers see. Buyers smell pets, then start looking for stains, scratched doors, and worn carpet, and that suspicion comes off the offer. A home that fewer buyers will even tour is a home that sits longer and slides in price.

Why buyers react to smell before anything else

Smell reaches a buyer before any room does. They open the door, take a breath, and decide how they feel about the place before they have looked at a single feature. A musty basement, stale smoke, or a litter box tells them the home was not cared for, and that story is hard to undo during a 20 minute showing.

The problem is that a bad smell reads as a warning sign. Buyers cannot always name what they are smelling, so they assume the worst, hidden water, a problem in the walls, something the seller is covering up. Even if the home is in good shape, the doubt is enough to lower an offer or kill interest.

Do not mask the smell

Plug-in fresheners and scented candles only stack a new scent on top of the old one, and buyers notice that too. A heavy floral cloud the moment you walk in is its own red flag. The smell has to be gone at the source, not covered.

What to do before you list

Handle the odor in the tight window before your listing goes live, working from the biggest sources down.

Treat before the first showing. Deal with the odor before the offers come in low, not after.
Start with the obvious sources. Carpet and padding hold smoke and pet residue, along with soft furnishings and the HVAC system, which can circulate a smell through the whole house.
Clean and seal hard surfaces. Hard surfaces can be cleaned and sealed, while some materials are past saving and are cheaper to replace than to keep fighting.
Bring in professional treatment where it soaked deep. Where the smell has soaked into a home, professional treatment pays for itself against the price drop you are trying to avoid.

We use green, non-toxic methods only, source removal, enzymatic and oxidizing treatments, thermal fogging, hydroxyl generators that are safe in occupied spaces, and HEPA with activated-carbon scrubbing. We never use ozone or chlorine, and we never mask the smell to get you through a weekend of showings.

Most jobs are gone in 1 to 4 hours, with same or next-day scheduling, which fits the tight window before a listing goes live. We are fully insured and back the work with a 100 percent guarantee. If it is not gone, we are not done. Our job is to get the smell out so the home shows the way it should.

The math usually favors fixing the smell

Compare the cost of treating an odor against the discount it invites. If thirdhand smoke can knock as much as 30 percent off a home, that is a six-figure swing on a mid-priced house, and an odor treatment is a small fraction of it. Even the lower end of the smoke estimate, up to 29 percent, dwarfs the cost of getting the smell out before you list.

Time on the market is its own cost. Every extra month carries a mortgage payment, taxes, utilities, and the quiet pressure that makes sellers accept a weaker offer. If more than half of buyers will skip a home that smells of smoke, clearing the odor widens your buyer pool and keeps the sale moving.

You do not need a number for every decision here. A home that smells clean simply shows better, draws stronger offers, and closes sooner. Removing the odor is one of the few pre-listing moves that protects both your price and your timeline at the same time.
