Why Contractors Bring Their Rigs Here

We've been in the pressure washing business for over 30 years, and the same techs who build and service our rental fleet work on customer machines. We stock the parts on site, which means most common repairs don't wait on shipping. And because we sell everything from pumps to repair parts, you'll get honest advice on repair versus replace.

Common Questions

Do I need an appointment?

No. Drop your machine off Mon-Fri 7:30-4. Call (301) 519-9274 first if you want a heads up on current turnaround time.

My machine runs but has no pressure. What's wrong?

Nine times out of ten it's the unloader, a nozzle worn out of spec, or pump valves. That's usually a quick, affordable fix - not a new machine.

Do you work on homeowner machines or just commercial?

Both. Commercial units are our specialty, but we repair residential pressure washers and small engines too. We'll tell you up front if a repair costs more than the machine is worth.

Do you sell the parts if I want to fix it myself?

Yes. Pumps, seals, unloaders, engine parts, guns and hoses are stocked at the counter, and we're happy to point you at the right part.
