If any of these sound familiar

If you've already tried everything else, this is your next call.

Those aren't failures on your part. Ozone and masking agents cannot destroy embedded odor residues in walls, fabric, and the HVAC. BIOSWEEP can.
How it works

What BIOSWEEP actually does

BIOSWEEP is a five-stage photocatalytic oxidation process. It generates hydroxyl radicals, hydrogen peroxide vapor, and singlet oxygen — a combination 10 times more oxidizing than ozone alone. These agents react with and break down the organic compounds that cause odor at the molecular level. When the source is resolved and the compounds are gone, the odor cannot return.

Ozone / Thermal fog / Primer
Masks
Creates a counter-odor that fades within days or weeks. Embedded smoke residues in walls, fabrics, and HVAC ductwork remain untouched. The smell returns on the first humid day or when the AC kicks in. These remedies waste time and money.
BIOSWEEP
Destroys
Reaches into wall cavities, HVAC ducts, and fabric fibers. Breaks down odor-causing molecules through oxidation. No masking, no sealing, no residue on surfaces. Safe on all materials. GUARANTEED results.

What does it cost?

We publish our prices because hiding them doesn't serve you. A range gives you enough to decide if a call makes sense. Every phone estimate is free and takes about 5 minutes. Please have square footage (including basement) and odor source ready.

From Chicagoland homeowners who called after trying everything else

★★★★★

"I purchased a home that had been smoked in for 10 years. I tried HVAC cleaning, professional wall cleaning, even Killz primer. Nothing worked. Grant was honest up front that he couldn't guarantee 100% removal because we had painted, but he did an overnight treatment of my whole house. The next day my home smelled fresh and there was no trace of the foul odors at all. I am beyond ecstatic with the results."

"Previous users had a cat urine smell in the basement. I ripped up the carpet and tried EVERY cleaning product on the market. Nothing worked. Less than 24 hours after BioSweep, the smell was COMPLETELY gone and the entire home was fresh for my family to move in."

"We were selling my childhood home and one portion smelled from cigarette smoke. After trying deep clean and ozone treatment, it was BioSweep that saved the day. The price was commensurate with the high level of service, transparency, and guarantee."

"Grant and his office staff coordinated the process with the insurance company and removed 100 percent of the smoke smell from the house fire. Extremely professional and genuinely concerned about the customer."

The treatment

What happens from the moment you call to the moment you re-enter

1
Assess and Schedule
Phone estimate in 5 min. No site visit required for a rough estimate. Find a 16-24 hour window to leave your home.
2
Prep
Vacate the home. NO people, pets, or plants can be present during treatment.
3
Treat
BIOSWEEP runs for about 10-15 hours. No access during treatment. Most projects run overnight.
4
Air-out
Carbon filtration and air-out process. BIOSWEEP gases decay to oxygen and water vapor.
5
Re-enter
Safely re-enter when our team confirms the treatment is complete. Typically the morning after treatment.
Pet and child safety
Yes. Pets and children return safely once our team confirms the treatment is complete.

BIOSWEEP uses no liquid chemicals. The gases generated (hydroxyl radicals and hydrogen peroxide vapor) return to oxygen and water vapor after the treatment ends and the space is properly aired out. No chemical residue remains on floors, fabrics, or surfaces.

Permanent.

The guarantee is simple: if odor of the treated type returns after the BioSweep Treatment and the original source has been resolved, we come back at no charge.
