About Us



Madexco was founded in 1961 by John D. Madden. Madden Excavating Corporation began with a dozer for basic dirt work and creating ponds for livestock. The shortened name of Madexco was created in the late 1970s, adding an expansion into pipeline services and trucking.

After John's passing in May 2016, his grandsons Mark and Johnny Jr., started Madexco Drafting Services, Inc. to carry on the service legacy started by their grandfather.


Madexco Drafting Services, Inc. specializes in customer and fabrication drawings for complex engineered products. The staff is comprised of decades of experience in power generation auxiliary equipment, process skid systems and structural steel drawing packages that have been delivered across the world. We have the ability to take an engineered concept and finalize the steps needed to take an idea to the production floor.


Collectively our designers have 100 + years of experience.
