About Us

Founded in May 2026 and headquartered in Lewisville, Texas, CMS Supply Group LLC is an independent, hyper-focused building envelope distributor built to solve supply chain delays for commercial, multi-family, and data center contractors across the Dallas-Fort Worth metroplex and northern growth corridors.

Unlike traditional, broad-catalog supply yards that dilute their inventory across thousands of unrelated SKUs, CMS Supply Group specializes exclusively in high-performance building envelope protection. We focus directly on what matters most to structural exterior contractors: premium self-adhering flashing tapes, weather-resistive air and vapor barrier membranes, and liquid flashing systems. By mastering a single product category, we offer deep technical expertise and guaranteed product compatibility.

We understand that waiting 2 to 3 days for standard freight can stall a commercial framing or window installation crew and destroy project margins. That is why we operate an agile, direct-to-jobsite delivery fleet utilizing dedicated mobile transport out of Lewisville. When your crew runs short on self-adhering flashing tape or window seals mid-installation, we drop materials straight to your project box within hours.

CMS Supply Group bridges the gap between major manufacturers and local trade contractors. We provide code-compliant, specification-grade materials designed to pass rigorous building inspections the first time, every time.
