Project Description

WSDOT Water Conservation Project 

Water efficient plumbing and aerator replacement for WSDOT.  The work is taking place at 79 sites across the state and many sites have multiple buildings per site.

I have had the privilege of working with Stewart Plumbing on serval projects over the last 6 years. Their craftsmanship and attention to detail is first-rate. The majority of the projects that we have worked on together are energy retrofit projects. It takes experience and problem solving skills to install new mechanical system within existing old buildings. Time and time again Stewart Plumbing’s ownership and their employees have proven that they have the problem solving skills to complete the most difficult of projects. They have also been able to provide the manpower to perform the work and meet the schedules on every project, while exceeding the owner’s expectations. This is the kind of professionalism we look for when partnering with a mechanical contractors and I would recommend Stewart Plumbing wholeheartedly.
