Commercial carpet cleaning costs $40 to $90+ per room or $0.25 to $0.50 per square foot on average, though many cleaning companies charge less per room or square foot for larger jobs and commercial settings. Other factors that influence the cost are the location, carpet type, and cleaning method.

Tips aren't expected for commercial carpet cleaning, but a general guideline for excellent service is to add 10% to 20% to the total bill.

Allow 20 minutes per room on average for commercial carpet cleaning if the rooms are in the 250 square foot range. Carpet cleaning time can vary significantly depending on the type of business and the size of each room. The setup process takes an additional 10 to 20 minutes. Cleaning time also varies based on furniture moving, carpet soilage, and spot treatments needed.

Carpets in commercial spaces should be professionally deep cleaned every 12 to 18 months for areas with low to moderate traffic. Commercial spaces with heavy foot traffic should be cleaned every 6 months.

Professional carpet cleaning is a worthwhile investment to remove dirt, stains, bacteria, dust, pollen, pet hair, and odors. It reduces allergens and mold while increasing indoor air quality and extending the life of the carpet, saving your business money over the long term. The best cleaning methods are:

• Steam cleaning: Hot water under high pressure extracts debris and revives matted fibers.
• Dry cleaning: Detergent is worked into the carpet then extracted along with trapped dirt.
• Carpet shampoo: Detergents loosen debris then get removed by steam extraction.
• Foam cleaning: Expanding foam encapsulates dirt before steam extraction.
• Bonnet cleaning: A machine with towel scrubs and extracts surface dirt.

Most commercial carpet cleaning companies will move small or basic furniture at no extra cost, while others may charge a small fee or decline to move anything at all. Be sure to ask up front before hiring and get a detailed estimate in writing.

Allow 6 to 24 hours for carpets to fully dry after commercial carpet cleaning. Drying time depends on the carpet material, cleaning method, humidity, circulation, and temperature. Use fans, open windows, and turn on AC to speed up the drying process.
