Do I need to replace urine-saturated carpet?
Not in most cases. Enzymatic treatment of the carpet, pad, and subfloor followed by Aero Machine deployment reaches surfaces a cleaning crew can't.
Why it happens
Urine odor persists because uric acid crystals embed in the carpet, pad, and subfloor. Surface cleaning often rehydrates these crystals, reactivating and worsening the smell. The source is the entire flooring system, not just the visible carpet pile. Complete odor elimination requires neutralizing these crystals where they have soaked in, which is often beyond the reach of standard janitorial methods.
What to check
First, check the subfloor for structural damage like swelling or rot; this damage may require replacement. If the subfloor is sound, ensure the cleaning method saturates the carpet, pad, and subfloor with a targeted enzymatic solution. Avoid using only water or standard carpet shampoo, as this can intensify the odor. Ensure the area dries completely to prevent mold growth.
When to call a professional
Call a professional if the subfloor is compromised (rotted wood, crumbling concrete) or if multiple in-house deep cleaning attempts fail to remove the odor. A specialist has the diagnostic tools to assess saturation levels and equipment to treat the deeper layers of the flooring system that standard cleaning crews cannot access.
How Luften handles it
Luften uses a combined process. First, an enzymatic treatment penetrates the carpet, pad, and subfloor to break down the uric acid crystals causing the odor. We then deploy Aero Machines. These units emit a dry vapor that bonds with and neutralizes any residual airborne ammonia and uric acid on all exposed surfaces. This approach eliminates the odor at its source and in the air.
