Pressure Washer Repair in Gaithersburg

Our shop repairs cold water and hot water pressure washers, including belt drive and direct drive machines, burner systems, and trailer rigs. Common repairs we handle:

  • Pump rebuilds and replacements (CAT, General Pump, AR, Comet, Udor, Giant)
  • Unloader valve diagnosis and replacement
  • Hot water burner service: ignitors, coils, fuel nozzles, electrodes
  • Engine service for Honda-powered machines

Most contractors can't afford a week of downtime. Tell us what the machine is doing (no pressure, pulsing, won't fire, leaking oil) and we'll tell you honestly whether it's a $20 part or a shop visit.

Why Contractors Buy From Us Instead of Amazon

Anyone can ship you a box. We answer the phone, tell you which unloader actually fits your 8 GPM machine, and warn you when the cheap part will cost you more in downtime. We've been supplying the pressure washing trade in Maryland since 1994, and our own family has run cleaning equipment in this county for decades. When you call, you talk to someone who has held the part in their hands.
