Company History

Founded in 1982, the company started as a single outlet supplying plumbing parts to Cape contractors. Over time it grew into four locations to meet seasonal demand and the needs of older coastal homes. The business expanded its inventory to include heating and excavation products and trained its staff to assist both do-it-yourself homeowners and commercial clients.

Being based on the Cape means staff are familiar with common local issues — salt air corrosion, older cast-iron piping, and homes that shift with the seasons. The inventory reflects that local knowledge.

Leadership

Leadership includes long-time industry professionals and managers who live and work in the area. The team brings decades of trade experience to daily operations and works with contractors, property managers, and homeowners.

Leaders keep close ties to local trade groups and suppliers and stay involved with community projects that affect housing and utilities on the Cape.
