Professional cleaning delivers measurable ROI through reduced employee sick days (saving $2,000-5,000 annually per avoided illness), extended life of carpets and furnishings (preventing premature replacement costs), and improved customer retention rates from positive facility impressions. Studies show that businesses with professionally maintained facilities see 15-20% higher customer satisfaction scores and experience fewer liability claims related to slips, falls, or health issues. When clients see a spotless, well-maintained facility, they instinctively trust your attention to detail in your core business services.
