Orange County, CA
Smoke odor is one of the most difficult indoor air quality problems to resolve because it doesn't just linger in the air — it penetrates walls, ceilings, HVAC systems, and porous materials throughout a property. OC Refresh specializes in permanent smoke odor elimination in Orange County homes, rental units, and commercial properties.
Tobacco and cigarette smoke leaves behind a sticky residue called third-hand smoke, which coats every surface in a room — walls, ceilings, window treatments, carpet, and furniture. This residue contains hundreds of chemical compounds including nicotine, which binds tightly to surfaces and continues releasing VOCs for months or years.
The HVAC system is one of the biggest challenges in smoke-contaminated properties. Every time the system runs, it circulates smoke-saturated air through the ductwork and redistributes residue throughout the entire property. Treating a room without addressing the HVAC system guarantees the odor will return.
Porous building materials absorb smoke deeply. Drywall, insulation, wood framing, and concrete can hold smoke compounds for years. In properties with heavy or long-term smoking, the contamination extends into the structure of the walls themselves — not just the surface.
Cannabis smoke presents similar challenges to tobacco but with a stronger, more distinctive odor profile. It leaves behind the same sticky resin residue and penetrates materials just as aggressively.
Painting over smoke-stained walls is the most common mistake property owners make. Standard paint does not seal in smoke compounds — the odor bleaches through within weeks. Only stain-blocking, odor-sealing primers specifically formulated for smoke can lock in residue before repainting.
Air fresheners and ozone generators from a hardware store provide temporary relief at best. Consumer-grade ozone machines lack the output needed to treat a full room properly, and air fresheners simply add fragrance on top of the contamination.
Cleaning walls with vinegar or cleaning products removes surface residue but cannot address the smoke compounds absorbed into the drywall and insulation behind the surface. The odor continues to off-gas from the structure itself.
Replacing carpet without treating the subfloor, walls, and HVAC system is an expensive fix that leaves the root cause untreated. The smoke residue in the remaining materials continues to contaminate the new carpet within weeks.
We measure baseline VOC levels, odor index, and particulate matter throughout the property and inspect the HVAC system, walls, and materials.
We clean all accessible hard surfaces to remove third-hand smoke residue before air treatment begins.
Hydroxyl or ozone treatment penetrates walls, ductwork, and materials to break down smoke molecules at the molecular level throughout the entire space.
Before-and-after air quality readings with a written report — ideal for landlords, realtors, and property managers needing documented proof.

If the treatment reaches the source contamination — including HVAC systems and wall surfaces — the odor will not return. We use air quality meters to confirm the result before we leave.
Yes. Wildfire smoke creates similar third-hand smoke contamination in homes and can be especially severe due to the intensity of the smoke and the variety of materials burned. We treat wildfire smoke the same way we treat cigarette smoke.
Absolutely. Realtors and sellers regularly call us when a property has smoke odor issues before listing. We provide same-day service and before-and-after documentation that can be used for seller disclosures.
Most residential smoke odor removal jobs in Orange County range from $200 to $800 depending on the size of the property and severity of contamination. Commercial or whole-home jobs can range higher. We provide a written quote before any work begins.
It depends on the treatment method. Hydroxyl treatment is safe for occupied spaces. Ozone treatment requires vacating the property for a few hours. We recommend the right method for your situation during the assessment.
