Our History

Gradient Construction was originally founded in 1992 by John Riffe with the goal of supporting residential construction projects in the largely rural Southern Maryland area. Initially, we specialized in installing residential septic systems, underground tanks, utilities, plumbing, and HVAC systems. As development began to increase in the area, the demand for our services grew, and we turned our focus to commercial work. Today, we have served a wide variety of commercial and government clients and have built water/sewage treatment facilities, pipelines, and pump stations throughout Southern Maryland. Our skilled workforce of 40 employees is dedicated to the company ideals of efficiency and quality-oriented work.
