The US carpet cleaning industry has faced significant volatility due to turbulent changes in disposable income and consumer confidence. Additional issues have arisen from substantial changes in consumer preferences in the industry. Despite this, the industry has maintained a steady performance in recent years, establishing itself as an essential service for households and businesses. Generating steady revenue over the past five years and home to a remarkably fragmented operator landscape, the industry thrives on routine demand from homeowners seeking healthier living environments and businesses needing spotless spaces. However, competition is fierce, barriers to entry are low and operators, even large franchises like Stanley Steemer, struggle to command a 5 to 6% market share, making local reputation and word-of-mouth recommendations crucial for success. Industry revenue has been expanding at a CAGR of 2.7% over the past five years and is expected to reach $6.9 billion in 2025, when revenue will rise by an estimated 1.1%. Despite revenue growth over the past five years, analysis reveals a slowdown and decline in profit margin. Profit has dropped from 10.1% in 2020 to 9.6% in 2025, impacted by rising costs and intensifying competition, especially from DIY cleaning solutions and substitute flooring options like hardwood. Demand for eco-friendly and non-toxic cleaning methods has shifted the playing field, as more companies adopt green practices to meet consumer preference shifts. However, this squeezes the margin even more, leading to higher supply and certification expenses. To stay competitive, many operators have added specialized services such as tile, upholstery and air duct cleaning, but the proliferation of DIY cleaning gadgets and online gig platforms has kept traditional carpet cleaning jobs under pressure. In the next five years, forecasts suggest moderate growth, with the profit margin stabilizing near 9.7%. Companies will continue streamlining operations by embracing energy-efficient equipment and mobile business models. Through 2030, operators will invest in digital marketing, automation and training to meet stricter regulations and evolving health standards, especially in urban and eco-conscious markets. As competition and substitutes continue to challenge the traditional market, businesses that diversify services, scale up green offerings and strengthen local relationships will be best positioned to overcome a maturing, increasingly competitive market. Revenue is forecast to rise at a CAGR of 2.0% over the next five years, reaching $7.6 billion in 2030.
