JTS Cleaning Services is a full-service building service contractor that provides cleaning services to Class A and Class B office buildings. In the past our customers have had to deal with inexperienced contractors who make a lot of promises, yet fail to follow through. Our customers appreciate the value of partnering with experienced, knowledgeable cleaning contractors who provide “healthy” cleaning solutions for their buildings, reliable service, and attention to detail.
