Pre-listing odor removal is one of the highest-ROI recommendations a realtor can make to a seller — and one of the most frequently overlooked.

When to Recommend Pre-Listing Odor Treatment

The easy cases: you walk in and immediately detect pet or smoke odor, the seller mentions pets or smokers have lived in the home, or the home has been vacant for an extended period and smells musty. The less obvious cases: the seller has nose blind and cannot smell the odor but buyers will, the home has older carpet with multiple pets even without visible staining, or a previous listing of the same property had odor-related buyer feedback.

How to Frame the Recommendation to Sellers

• "Buyers who smell an odor make lower offers. The treatment cost is typically 10-20% of the negotiating concession we would face if we listed without it."
• "Professional documentation of the treatment also protects you in the disclosure process."
• "Same-day service is available — we can have this done before listing photos."

What to Expect from a Professional Treatment

• Source assessment — UV inspection for pet odor, visual inspection for smoke
• Honest scope — the vendor should tell you upfront if carpet needs replacement vs treatment is sufficient
• Professional treatment with ozone or hydroxyl plus enzyme for pet source
• Written before-and-after air quality report for your disclosure file
• Timeline that fits your listing schedule — ideally before photography
