Custom Architectural Surfaces & Enclosure Systems
Since 1985, M G McGrath, Inc. has been an award-winning leader in the design, fabrication, and installation of architectural surfaces in the commercial construction industry. Performing work in the 48 contiguous United States, we specialize in custom architectural exterior enclosure systems. Known for creative solutions and master craftsmanship, we self-perform much of our own work to ensure smooth communication and transitions as a project moves through its lifecycle. MG McGrath Inc. has successfully completed some of the most complex architectural designs, all while maintaining the highest levels of safety and quality in our shop and field. We pride ourselves on being true partners and having a passion for excellence from concept to completion all backed up by proactive management and innovative solutions. Our collaborative approach to design assist is centered around adding value and ensuring open communication so everyone on the project team is on the same page.We have been at the forefront of the shift to prefabricated systems, like modular construction, for a project execution that is faster and safer. From rainscreens to curtain wall and punched windows, as well as manufactured brands to custom fab, we have been installing stick-built enclosure systems for over 35 years. Our in-house finishing team has combined chemistry and artistry to create our own line of custom, pre-patinated finishes on a variety of metal substrates. Whether it's perforated imagery, wall art, or ornamental cladding, we have the craftsmanship and artistic character to meet your vision. Our proactive and holistic approach ensures safety and quality-driven practices from concept to completion.

Services
Custom Metal Finishes
Our in-house finishing team combines chemistry and artistry to create proprietary pre-patinated metal finishes. We offer zinc, bronze, copper, and steel options with natural weathering effects, including Everest (zinc), Gunnison (copper), and Rainier (steel) finishes. These custom surfaces enhance architectural designs with lasting visual appeal and durability.
Rainscreen Systems
We design and install high-performance rainscreen systems that protect buildings while delivering aesthetic value. Our solutions include flat lock, h-seam, and s-slip panels made from metal, composite materials, and ultra-high-performance concrete. These systems provide weather resistance and modern architectural styling for commercial structures.
Unitized Curtain Wall
Our patented unitized curtain wall systems combine glass and panel components prefabricated in controlled shop environments. This approach ensures precision manufacturing and faster field installation. The systems meet high-performance requirements for thermal efficiency, structural integrity, and design flexibility in commercial buildings.
Modular Facades
We specialize in volumetric modular facade systems that streamline construction timelines. Our prefabricated components include cladding support frames and panel assemblies manufactured to exact specifications. This method reduces on-site labor while maintaining quality control through controlled environment fabrication.
Retrofit & Renovation
We revitalize existing structures with modern enclosure systems while preserving historical authenticity. Using laser scanning technology, we assess existing conditions to develop retrofit solutions that meet current codes. Our services enhance building performance, aesthetics, and commercial value without full-scale reconstruction.
