DeJean Companies
General contractors for the industrial market.

Industrial Construction & Maintenance

DeJean, an industrial general contractor, offers the best of both worlds — the expertise and reputation of a large company and the personal, hands-on approach of a Deer Park based local business.

We provide contractor services for new construction and revamp projects as well as small capital maintenance work.

Our one stop shop allows us to take projects from site preparation through project start-up using direct hire DeJean personnel and strategic partnerships with specialty contractors.

Using our in-house software, we have the ability to effectively manage projects by providing weekly cost updates, productivity reports based on the man-hours worked, progress reports and CPM schedules on a project-by-project basis. We track time and material projects against a pre-established budget to account for production, just as if they were part of a lump sum contract. Taking advantage of two week look ahead schedules, we review work that was completed the previous week and look ahead two weeks at a time towards actions that need to take place to maintain project progress.


DeJean is authorized to use the ASME "R" stamp symbol in accordance with the applicable rules of the ASME Boiler and Pressure Vessel Code.
