From small projects to big dreams... COS Construction has been serving the Illinois Metro East and the city of St. Louis since 2007. We began as a small company doing small projects, but as demand for our remodeling services grew, so did our company. In two short years, we have added several master craftsmen; have a fleet of service vehicles, and we now the capability of taking on projects large and small thanks to the combined knowledge and experience of our team.We can handle smaller jobs such as residential roofing, gutters, siding, window replacement and landscaping quickly and cost efficiently.Our crews also demonstrate expert craftsmanship in larger projects, such as second story additions, kitchen and bath remodels, and new home construction.
