What Sterling Builds

• Acquired Professional Plumbing Group in 2023 to expand residential services in the Dallas-Fort Worth area.
• Began a strategic downsizing of the Texas heavy highway business in early 2025 to focus on higher-margin work.

Operational Strengths

The company maintains a flexible business model that allows it to bid on mid-sized projects that are often too small for international firms but too large for local contractors. Sterling focuses on mission-critical projects where schedule assurance and specialized technical skills are required by large customers.
