General Contracting and Excavating

About Us


Wilmco was built on the basis of honesty, pride in workmanship and quality materials for a fair price while always putting the visions of the customer as a top priority to a successful project. The company was established in 1991 when it's founder, James R. Wilmering, (Randy) decided he wanted to spend more time around his family. Prior to this decision he had spent six years traveling the country building stores and mall buildouts for C.DS Mestel out of New York. The previous two years were spent with Knoebel Construction, Inc out of St. Louis working on commercial accounts such as the Galleria and West County mall. Before signing on with Knoebel he worked  on Union Station with the C. Rallo Contracting Co. as a journeyman. Randy's union career began in 1979 as a trade school apprentice with Missouri Builders, primarily building custom homes for the general public, until the company closed. Before beginning his apprenticeship he worked as a painter and handyman for Joe Clark . During high school Randy took on part time work as a laborer with a rehab company mostly in the field of demolition.


During his career working for other companies Randy supplemented his income by taking on small side jobs under the name Wilmering Custom Builders and Remodelers. When the decision was made to focus on his own company the lengthy name was changed to Wilmco. The company's origin was in residential and commercial construction, building, remodeling and renovating all types of projects for all kinds of property owners. Projects included work on the Stonewolf subdivision and St. Clair Mall in Illinois as well as Helzberg Diamonds and Life Uniform in Missouri and Illinois. After several years, the work load from one commercial company as well as renovations and rehab for a few customers including the company's own properties, Wilmco needed to limit its residential work with the general population.


In the past few years the decision was made to return Wilmco to its roots (and Randy's true love) of making the dreams of the general public come to life.  Whether it is new construction, remodeling, renovation, custom woodworking or cabinets, residential or commercial, if our clients can envision it we can build it or fix it. In 2009 an excavation and landscaping division was added to better serve our customers by offering an even wider variety of services.

Master Carpentry:

Randy's years of experience and skill in every aspect of  construction and carpentry, has earned him the title of Master Carpenter. With the field becoming so specialized in the past several years many carpenters are experienced and skilled in only a particular portion of construction such as framing or finishing. When you work with Wilmco you can feel confident that the person overseeing your project has the knowledge and skill to make sure that every aspect of the job is done with the highest degree of quality and pride.


To grow every division of Wilmco by earning the trust and confidence of everyone we work for by offering quality work, fair prices and a genuine concern for the needs of the people who hire us.
