Options for repair vs replacement
We’ll help you decide whether fixing your machine is worth it based on age, condition, and parts availability.
Pressure washer performance depends on two systems working together: the engine and the pump. That’s why our repair process in Denver includes a full inspection of both. Most machines that won’t start, lose power, or fail to build pressure have underlying issues such as clogged carburetors, fuel contamination, worn pump seals, faulty valves, or overheating pumps.
We provide complete pressure washer restoration through carb cleaning, oil replacement, spark plug service, pump flushing, seal replacement, and unloader valve inspection. We test the machine under load to measure PSI output, identify cavitation issues, locate internal pump damage, and verify stable operation across different spray tips.
Contractors and homeowners trust us because we provide clear diagnostics, honest recommendations, and efficient turnaround times. Our goal is always to repair the machine affordably and correctly — without unnecessary part replacements or guesswork.
This is usually caused by worn pump seals, faulty unloader valves, clogged nozzles, or engine performance issues. We diagnose the exact cause.
Most starting issues come from stale fuel, clogged carburetors, bad spark plugs, or ignition problems. A complete tune-up typically fixes the issue.
Yes. We inspect and service pumps, including seals, unloader valves, cavitation issues, and PSI output testing.
We repair Honda, Simpson, DeWalt, Generac, Predator, Briggs & Stratton, Troy-Bilt, and most gas-powered units.
