Flashing is one of the most important components of a commercial building envelope. It directs water away from vulnerable transitions, openings, and penetrations, helping protect the structure from moisture intrusion and the costly damage that can result when water finds its way behind exterior materials.
Division 7 Waterproofing installs commercial flashing systems that work together with waterproofing, air barriers, masonry, and exterior wall assemblies to create a continuous defense against water intrusion. Our experienced crews understand that successful flashing installation is all about the details.
The Details Matter
Even the highest-quality building materials can fail if water is allowed to bypass critical transitions. Proper flashing protects windows, doors, wall openings, expansion joints, roof-to-wall connections, and other areas where moisture is most likely to enter the building.
Our crews focus on correct sequencing, material compatibility, and precise installation to help ensure every flashing system performs as intended throughout the life of the structure.
