Our outstanding team is committed to the STS process, and we boast one of the lowest employee turnover rates in the industry. Many employees have been with STS for 10 or 15 years or more—some since our founding in 2000—drawn by an excellent benefits package and a company culture that prioritizes family/work balance.

Maintaining this high standard of customer care requires hiring, training, and keeping exceptional employees who share this passion. While other companies subcontract most of their work, we perform almost every trade with our highly trained workforce—from estimators and project managers to drywallers, painters, electricians, and plumbers.
