Treadwell Pump house re-roofing begins

Chris Diamond hands materials up to Tim Crondahl as the North Pacific Erectors crew prepares to start work on the Treadwell Mine Pump House in Douglas on Thursday.

Chris Dimond remembers spending his childhood playing at Sandy Beach with the Treadwell pump house always just offshore, and, as he grew, the iconic landmark continued to be part of his life.


First, it served as the backdrop for many of his wedding pictures. Later it became the focus of his home’s art collection.

Thursday it became part of his job.

Dimond is one of two foremen from North Pacific Erectors working to replace the deteriorating roof on the old pump house.

The duo’s first task is installing a new floor that will support an interior frame designed to hold up the new roof. It’s a routine procedure compounded by the tides — at high tide the pump house is only accessible by boat.

To complete the task, Dimond and coworker Tim Crondahl, are using a ladder attached to the building to carry supplies from the boat inside. The process will likely take about two weeks, but it is possible it could take a month.

The workers are using pressure-treated wood for the flooring and interior frame. The roof will be constructed of red metal.

Aside from the new building, Dimond and Crondahl will be sealing off access to inside the building to prevent animals or people from getting in and threatening the iconic landmark’s structural security.

The building’s supporting materials are in fine condition, but the upper portion above the waterline has deteriorated extensively in recent years — likely due to the weather, Dimond said.
