What our customers say:

“DePatco has completed numerous pipe installation projects including water and sewer projects. We have never had problems with their scheduling, project management, construction work, required paper work and other aspects of complicated construction projects. They are not change order driven and have always maintained a workable and professional attitude during and after construction.”
