About Mountaintop Mechanics

Practical DPF support for the Columbia River Gorge

Mountaintop Mechanics is preparing a professional off-truck diesel particulate filter cleaning service for the people and businesses that keep Gorge equipment moving.

What we are building

The planned service is centered on careful intake, filter inspection, measured cleaning, and post-clean verification. The goal is to give diesel owners, repair shops, owner-operators, and fleet teams clear information before they decide whether a filter should be cleaned or replaced.

Where we plan to serve

  • White Salmon, Washington
  • Hood River, Oregon
  • The Dalles, Oregon
  • Columbia River Gorge

The facility and opening schedule are still being finalized. We are not accepting service appointments yet.
