Lyon & Associates is a full-service building envelope consulting firm based out of the Columbia South Carolina area. 


We began business in 2008 with a commitment to deliver practical solutions and an unmatchable level of service to its clients. Every year since its establishment we have experienced significant growth by embracing the simple philosophy of "working hard to work again". We believe, if done well, each project leads to the next project. There is simply no better testament regarding our client's level of satisfaction than the fact that they rehire us. 


Since our inception, we have worked closely with a wide variety of clients in a number of different capacities. Our list of clients includes Fortune 500 companies, non-profits, healthcare facilities, the federal government, public universities, public school districts, and city and county governments. We perform investigative work, develop roofing databases for multiple facility clients, provide guidance for short and long-range planning, help our clients maintain their existing roofing assets, design and manage roofing and waterproofing projects from inception to completion.


In the event that it is determined a project requires the expertise of other disciplines, Lyon & Associates has developed strategic relationships with other firms so that we can deliver "holistic" building envelope solutions that provide the best long term results for their clients.


We believe in earning the clients' business by working steadily to build our credibility and gain their trust.  To that end we strive to outwork other firms and to provide unparalleled support to those that choose to work with us.

We are interested in your problem regardless of size and complexity.  We welcome the opportunity to demonstrate how hard we'll work for you!
