Agents who call us before they need us

★★★★★

"I am a Broker and used BioSweep on a listing I had. My listing was a very large home that received many comments on how beautiful it was but smelled of cigar smoke. We tried everything. As a last ditch effort I contacted BioSweep. They came out right away. The smell of the cigar smoke was gone. My second showing after the BioSweep service purchased the house. I will use on another listing if needed."

"I am a Realtor and used BioSweep for a listing where a smoker lived. It was amazing. They came in and when they finished it was a smoker-free home."

"Collin was resourceful and listened to what I needed to get a Hanover Park, Illinois condo ready for sale. There was a strong animal odor that he removed with two available processes. The listing sold after a few days. I highly recommend this service."

Realtor FAQs

The questions agents ask before the first call

How fast can you treat a listing before it goes live?
All in, the BioSweep treatment usually takes about 24 hours. If we treat your listing today, you can show it tomorrow afternoon.
Who pays, seller or agent?
Almost always the seller, on the agent's recommendation. The math makes the conversation easy: $1,000-$3,500 treatment vs. $30,000-$60,000 price reduction risk. We can give you an estimate over the phone so you have a number to show the seller. Sometimes when the BioSweep Treatment is requested by the buyer, our invoice is credited to the sale of the home.
What documentation do I give the buyer?
We deliver a professional Treatment Certificate within 24 hours of completing the job. The certificate includes the property address, treatment date, BIOSWEEP process summary, and the terms of the transferable warranty. It goes directly into the disclosure package. Some agents include it in the listing photos as a trust signal before showing.
Does the buyer inherit the warranty?
Yes. The BioSweep warranty is transferable to the buyer at closing. If any odor of the treated type returns after the original source is resolved, we provide a secondary treatment at no charge. For the seller before closing, or the buyer after. The warranty transfers automatically with the certificate. No additional enrollment or paperwork required.
Will a buyer's inspector still flag it at inspection?
If the treatment is complete and effective, there is nothing for an inspector to flag, because there is no odor present. Buyers with concerns can review the Treatment Certificate and warranty before the inspection phase. Our 5.0 stars across 30 Google reviews over 13 years is the track record behind that claim.
