Commercial Cleaning Services, Connecticut

Connecticut’s Trusted Commercial Cleaning & Janitorial Partner

Redefining clean across the Constitution State.

Founded in 1978, 4M Building Solutions expanded into Connecticut with the April 2024 acquisition of Horizon Services. By combining Horizon’s decades-long local presence with our 45+ years of precision-grade expertise, we’ve raised the bar for commercial cleaning services statewide, serving Hartford, New Haven, Stamford, Bridgeport, Waterbury, and beyond.

We’re the cleaning company built for Connecticut’s facility realities: staff turnover, rising costs, inconsistent results, and limited oversight. Our local management and regional support in Hartford deliver fast response with national-scale resources.
