At EDS, we’re committed to building lasting and valuable business relationships with our clients by consistently providing the value and service that keeps EDS at the forefront of our industry. This commitment makes EDS the premier provider for quality commercial waterproofing, restoration, and exterior maintenance.

Our mission is to enable property owners to overcome the waterproofing and exterior maintenance challenges they inevitably face. Our services are performed by licensed and highly qualified technicians who are trained to provide you with the best service using cutting-edge techniques and technology.


Our Story

Exterior Diagnostic Services, LLC (EDS) was founded in 2002 by Michael MacDonagh, IV following his retirement from the military after 20 years of service. Starting with just one truck and two men, Mr. MacDonagh IV grew EDS into a thriving waterproofing and restoration business. From the beginning, EDS emphasized quality and setting high standards by utilizing the best materials, highly trained craftsmen, and focusing on delivering the “best of the best” service.

In 2005, Michael MacDonagh, V joined EDS while still attending East Carolina University. He quickly grew to love the industry and the people, working his way up from laborer, to project management, to sales, to now his current role as President. Throughout his career, Michael V has been actively involved in the industry serving as the Past President of the Sealant, Waterproofing, and Restoration Institute (SWRI) and earning the 2023 SWR Institute NextGen Leaders Under 40’ Award.

The commitment to being “The Industry Best” by delivering value and quality while building lasting relationships with our clients has never faltered throughout the years. This commitment is what still drives EDS— a Valcourt Company, today.
