Who we are
One licensed team for plumbing, gas, remodeling and construction
Most projects stall because three different contractors are waiting on each other. GPIS keeps plumbing, gas, remodeling and general construction under one roof, so permits, trades and inspections move on a single schedule.
We work across Maryland, Washington DC and northern Virginia for both homeowners and commercial property managers — from a single water heater swap to a full building rough-in.
