Janitorial Services

The 63,000 janitorial service providers in the US clean building interiors, windows, and the interiors of transportation equipment, such as aircrafts. Specialized services include disaster recovery, medical cleaning, and mold clean up. Some companies provide outdoor services, such as snow removal and lawn maintenance. Non-residential customers, such as those in institutional, office, and commercial buildings, account for 80% of industry revenue.

Immigration Laws

Most janitorial jobs do not require workers with English-speaking skills, and tend to attract both legal and undocumented immigrants.

Green Cleaning

Growing concern with the environment and sustainability issues has led to increased demand for the use of eco-friendly cleaning products and methods.

Oct 19, 2026 - Janitorial Contractors Double Plans for Robotic Cleaning Equipment

• The share of US building service contractors planning to adopt robotic floor cleaning equipment doubled from 16% in 2025 to 32% in 2026, according to a market study highlighted in a report by the Building Service Contractors Association International (BSCAI). Planned use of artificial intelligence for administrative and marketing functions increased from 29% to 41%, while 38% of contractors anticipated greater customer demand for automation and technology, up from 25% in 2025. The findings reflect growing interest in technology as janitorial businesses contend with labor shortages, higher wages, and rising customer expectations. Automation could help cleaning contractors improve productivity, reduce repetitive tasks, and strengthen service consistency. However, equipment costs, training requirements, and uncertain investment returns remain potential obstacles.
• ABM Industries reported a 4.2% year-over-year revenue increase to a record $2.3 billion for its fiscal third quarter ended July 31, 2026, according to results released September 8. Growth included 2.1% from existing operations and 2.1% from acquisitions. However, revenue in its Business & Industry segment declined 2.6%, reflecting the loss of a major UK customer and continued softness on the US West Coast. Manufacturing & Distribution and Aviation revenue increased 17.6% and 12.5%, respectively. The results illustrate uneven demand for commercial facility services, including janitorial operations. For US cleaning contractors, stronger activity in manufacturing and transportation facilities could create growth opportunities, while weakness among commercial property customers may increase competition for contracts and pressure pricing.
• Rapid data-center expansion is opening a specialized growth market for US janitorial services, with 4,998 US data centers operating as of August 2026, according to a CleanLink report. These facilities require cleaning methods that control dust and contamination without damaging sensitive electronics, creating demand for trained contractors, antistatic products, and tightly controlled cleaning protocols. The opportunity comes as 42% of building service contractors already report intentionally using AI in their operations, suggesting the industry is increasingly equipped to serve technology-intensive facilities. Data-center cleaning may require more specialized expertise than conventional office work because improper wipes or materials can cause electrostatic discharge and pose equipment risks. For janitorial firms, continued AI-driven data-center construction could diversify customer portfolios and create higher-value contracts, but success will require specialized training, products and strict quality controls.
• US janitorial services face a tougher profitability outlook as wage, chemical, and equipment costs rise faster than operators can easily pass them through to customers, according to a recent ISSA report. Because contracts are highly price-sensitive, cutting service quality or sharply raising prices risks client losses, putting more pressure on building service contractors to improve productivity. Labor-saving equipment can materially change unit economics: backpack vacuums can increase cleaning productivity from about 2,500 to 7,000 square feet per hour. Automated chemical-dilution systems, preventive maintenance, and multifunction equipment can also reduce supply waste, downtime, and capital costs. Looking ahead, IoT-based cleaning schedules could further improve margins by matching labor and chemical use to actual building traffic rather than fixed routines.
