Permanent Odor Removal Service for Chicagoland Homeowners

The smell isn't going away.
It can.

PHOCATOX destroys smoke, pet, and embedded odor at the molecular level. I don't mask it. If anything comes back after treatment, I re-treat at no charge.

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 HVAC. PHOCATOX can.
How it works

What PHOCATOX actually does

PHOCATOX 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
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. You are not fixing anything - you are buying time.
PHOCATOX (BioSweep)
Destroys
Reaches into wall cavities, HVAC ducts, and fabric fibers. Breaks down odor-causing molecules through oxidation - not masking, not sealing. No residue on surfaces. Safe to re-enter one hour after treatment ends. Nothing left to come back.

From Chicagoland homeowners who called after trying everything else

★★★★★

"Three years ago a different company ozone-treated this house. I could still smell it in the bedrooms. BioSweep did it once. It's been two years - completely gone."

Dan K.
Naperville homeowner
★★★★★

"We moved into a house that smelled like cigarettes. The seller said they didn't smoke. Grant walked through, gave us an honest scope, and treated it for a fair price. My kids' rooms don't smell anymore."

Jennifer L.
Wheaton homeowner
★★★★★

"I was skeptical. I'd already tried two other companies. Grant explained the science without condescending. The price on the phone matched the invoice. The smell is gone - 18 months and counting."

Robert T.
Oak Park homeowner
★★★★★

"Pet odor in hardwood floors. I was told I'd need to rip everything out. Grant said let him try first. One treatment. The smell is gone and the floors are fine."

Full treatment FAQ: How long does smoke odor removal take? →
Pet and child safety
Yes - pets and children can return one hour after treatment ends.

PHOCATOX uses no liquid chemicals. The gases generated - hydroxyl radicals, hydrogen peroxide vapor - decay back to oxygen and water vapor within 30-45 minutes after treatment ends. No chemical residue remains on floors, fabrics, or food surfaces. Birds and aquariums should be covered and moved during treatment. Re-entry protocol for all pets is one hour post-treatment.
