Carpet smells bad? Here's Who to Call
Persistent carpet odor — musty, sour, or pet-related — usually means bacteria, mold, or organic matter trapped in the carpet pad or fibers. Regular vacuuming and air fresheners mask but don't eliminate the source. Professional carpet cleaning with enzyme-based pre-treatment ($120–$300) breaks down odor-causing bacteria at the molecular level. For severe pet odor, the pad may need replacement ($2–$4/sq ft) since urine crystals reactivate with humidity. Mildew smell often indicates moisture trapped under the carpet, which requires both drying and antimicrobial treatment to prevent health issues.
