Orange County, CA
Whether from pets, elderly residents, or other sources, urine odor is one of the most persistent and unpleasant indoor air quality problems a property can have. OC Refresh uses professional enzyme treatments, UV detection technology, and air treatment to permanently eliminate urine odors in Orange County homes, rentals, senior living facilities, and commercial properties.
Fresh urine has a relatively mild smell — it's what happens over time that creates the persistent, difficult-to-remove odor. As urine dries, bacteria break down the urea and other compounds, producing ammonia and other strongly-scented byproducts.
The uric acid component of urine is the main long-term problem. Uric acid crystallizes as it dries and binds tightly to whatever surface it contacts. These crystals are highly stable — they resist most standard cleaning products and can remain active in materials for years.
Humidity causes uric acid crystals to reactivate and release odor again. This is why a room that smells acceptable in dry weather can become overwhelming after rain or on a humid day — the moisture is reactivating dormant crystals throughout the space.
In properties with elderly residents or heavy pet use, urine can penetrate through multiple layers of flooring — carpet, padding, subfloor, and even into the concrete slab below. At this level of contamination, surface treatment alone is never sufficient.
Standard cleaning products — even those labeled for odor removal — work by masking or neutralizing surface odors. They cannot reach uric acid crystals embedded in carpet padding, subflooring, or concrete. Within a few days, the odor returns as the crystals continue off-gassing.
Enzyme-based cleaners available at pet stores are effective for fresh accidents on carpet surfaces. For old, deeply-embedded urine or contamination that has reached the padding and subfloor, retail enzyme products simply don't have the concentration or volume to do the job.
Steam cleaning is one of the most common and counterproductive approaches to urine odor. The heat from steam reactivates uric acid crystals and drives moisture — and the crystals — deeper into the materials below. The odor often worsens immediately after steam cleaning.
For senior living facilities or rental units with long-term contamination, replacing carpet without treating the subfloor, walls, and air is an expensive fix that fails quickly. The underlying contamination continues to work its way into new materials.
We use ultraviolet light to map every urine contamination spot in the space, including hidden areas behind baseboards and under furniture.
Professional-grade enzyme solution applied at the right concentration to penetrate through carpet into padding and subfloor, breaking down uric acid crystals at the source.
Hydroxyl or ozone treatment clears airborne urine odor molecules and neutralizes secondary bacterial odors throughout the space.
Before-and-after air quality readings confirm the odor has been eliminated. Written report provided for your records.

Final price depends on space size and severity
Yes, with the right treatment. The key is reaching the uric acid crystals in the padding, subfloor, or other porous materials where they live. Professional enzyme treatment at the right concentration, combined with air treatment, permanently eliminates the source.
Yes. Urine odor in senior living and assisted care facilities is a significant challenge and one of our most common commercial requests. We work discreetly, professionally, and around facility schedules. COI documentation is provided same-day.
We use professional UV (ultraviolet) light, which causes urine deposits to fluoresce in low light, revealing contamination that is invisible to the naked eye — including spots under furniture, behind baseboards, and in corners.
Most residential urine odor jobs range from $150 to $500. Commercial or whole-home jobs with heavy contamination can cost more. We always provide a written quote before starting.
Yes. The enzyme treatments we use are non-toxic and biodegradable. If we use ozone treatment for heavy contamination, we recommend vacating the space for a few hours, but the space is safe to return to after airing out.
