Guaranteed Odor Removal & Air Purification Services in Portland, OR

Lingering odors from smoke, mold, pets, sewage, or decomposition can permeate structural materials and contents, rendering a property uninhabitable even after the source has been cleaned. These smells are caused by microscopic volatile organic compounds (VOCs) that ventilation cannot eliminate. Traditional methods like masking sprays or candles are ineffective and only provide temporary relief.

Our Guaranteed Odor Removal & Air Purification service provides a permanent solution by neutralizing the odor molecules at their source. After the physical source of the odor is removed, we utilize advanced chemical and atmospheric treatments. We apply penetrative chemical deodorizers (via fogging or injection) to structural elements and run high-output ozone or hydroxyl generators to neutralize airborne and embedded VOCs. This multi-stage process guarantees the permanent elimination of the most stubborn and pervasive odors.

Our 3-Step Odor Removal Process

STEP
1

Source Identification and Deep Cleaning

We precisely locate the embedded source of the odor (e.g., deep carpet fibers, structural wood, HVAC ducts). The source material is cleaned, treated, or safely removed to eliminate the physical contaminant.

STEP
2

Atmospheric and Penetrative Neutralization

We use specialized equipment (thermal foggers, vapor systems) to apply neutralizing chemicals deep into porous materials. Simultaneously, we run high-output ozone or hydroxyl generators to break down airborne VOCs.

STEP
3

Verification, Ventilation, and Testing

The property is professionally ventilated to remove all traces of treatment chemicals. We verify the odor is completely neutralized, often using a “sniff test” or air quality testing before clearance is issued.

Q&A

What is the difference between ozone and hydroxyl generation for odor removal?

Both are powerful oxidizers that break down odor molecules. Ozone ($O_3$) is stronger and highly effective but must be used in an uninhabited, sealed area. Hydroxyl generators create hydroxyl radicals, which are safer for use in spaces with remaining contents or materials, but are generally less powerful than ozone. We choose the appropriate technology based on the loss.

Pet urine deeply crystallizes in porous concrete. We treat this by aggressively cleaning the surface and then applying specialized enzyme-based deodorizers that break down the urine crystals (salts) into manageable, odorless compounds. This often requires repeated treatments, followed by concrete sealing or encapsulation to prevent odor off-gassing.

No. Both processes require the property to be vacated of all humans, pets, and plants during the treatment period. Once the process is complete, the area is thoroughly ventilated until ozone levels return to normal ambient concentrations, which we verify before allowing re-entry.

Yes, with the caveat that the physical source is entirely removed first. Once the source is eliminated (e.g., all burnt materials, contaminated drywall, or decomposition waste), our multi-stage neutralization process provides a guarantee that the embedded VOCs causing the odor will be permanently eliminated, restoring the property’s air quality.

We take careful steps to protect sensitive items. We may pack out high-value or highly porous items for off-site treatment if needed. While ozone/hydroxyl generators are safe when used properly, their use requires a controlled environment, and we always follow strict manufacturer guidelines to prevent any adverse reactions to materials.
