Pet Urine Stain and Odor in Carpet? Here's Who to Call

Pet urine that soaks through carpet fibers into the pad and subfloor creates a persistent stain and ammonia-like odor that surface cleaning cannot eliminate. Uric-acid crystals bond to the fibers and reactivate with humidity, causing the smell to return repeatedly. A professional carpet cleaner uses enzymatic pre-treatments to break down uric acid, performs hot-water extraction that reaches deep into the pad, and can apply encapsulation sealants to the subfloor when contamination is severe, fully neutralizing the stain and odor at their source.
