About Us



Madexco was founded in 1961 by John D. Madden. Madden Excavating Company 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 Services, Inc. to carry on the service legacy started by their grandfather. Madexco incorporated in 2017 and began with two drafting resources. 



Madexco Services, Inc. specializes in customer and fabrication drawings for complex engineered products, field leadership for retrofit and installation teams and can provide multiple types of filters to meet any filtration need.
