Generator Enclosure Repair or Replacement

In coastal areas, where generators are exposed to humid salty air, their enclosures tend to wear out fast due to corrosion. Often the generator and engine are in good condition, but rust has destroyed most of the enclosure, chassis, and base.

In these kinds of circumstances we recommend that you replace the enclosure rather than discard the entire generator. This procedure can save you thousands of dollars in generator replacement costs.

Contact us if your generator needs to have the enclosure replaced.
