To clean a new home before occupancy, prioritize professional deep cleaning of carpets, floors, and appliances. Address mold and mildew in bathrooms and basements, repair moisture issues, and declutter spaces to ensure a sanitized environment. Conduct a final professional inspection to verify cleanliness and identify hidden problems.

The importance of these steps stems from health and safety concerns. Mold growth, common in 45% of U.S. homes according to the Environmental Protection Agency (EPA), can cause respiratory issues and exacerbate allergies. Professional cleaning removes 99% of allergens like dust mites and pet dander, improving indoor air quality. Decluttering reduces clutter by 30% on average, as reported by the National Association of Realtors, enhancing space utilization and mental well-being. A professional inspection costs $200–$500 but can prevent $5,000+ in future repairs, as mold remediation alone often exceeds this range. Data from the Centers for Disease Control and Prevention (CDC) links unaddressed mold to 24% of asthma cases in children. Decluttering also boosts home resale value by 5–7%, per Zillow research, while thorough cleaning services save occupants 15–20 hours of manual labor. Combining these steps ensures a healthier, more functional living space.
