New service customers: first diagnostic hour half off — mention it at drop-off.
Service rates — simple and flat
| Work | Rate | Notes |
|---|---|---|
| Maintenance, repairs & diagnostics | $100/hour | $100 minimum on all service |
| Hot water system work | $120/hour | Coils, burners, igniters, fuel systems |
| Welding & fabrication | $120/hour | Rigs, trailers, mounts, repairs |
No mystery line items: you pay for the hours it takes, quoted before we start. Diagnostics count toward the $100 minimum — if the fix takes the hour, the look-over was free.
Maintenance
Tune-ups, oil and plugs, carb cleans, pump oil changes, seasonal service and winterization — the stuff that keeps breakdowns rare.
Repairs
Engines, pumps, unloaders, valves and plumbing — pressure-tested before pickup. Most common repairs are back in 2–3 days because we stock the parts wall we wrench with.
Hot water & burner work
Coils, igniters, fuel pumps, thermostats — the finicky systems most shops won't touch. $120/hour, quoted same day.
Welding & fabrication
Cracked trailer frames, reel mounts, tank cradles, custom rig work — welded here, $120/hour.

What we work on
If it runs on a small engine or moves water, bring it in: pressure washers (cold and hot water), soft wash rigs and 12V systems, surface cleaners, pumps of every brand we sell — General Pump, Comet, AR, Udor — and small engines across the board, Honda GX-series above all. Trailers and rigs too, welding included. We stock the parts we wrench with, so most repairs don't wait on shipping.
Landscaping & commercial equipment
Landscaping crews and contractors: we service the machines your schedule depends on — commercial mowers and zero-turns, blowers and trimmers, generators, and compaction equipment like plate compactors. Same flat rates, same same-day diagnosis, and drop-off that works around your route. Bring one machine or the truck-bed's worth.
Honda Engines authorized dealer. We stock genuine Honda GX-series replacement engines, so when a repair isn't worth it, the swap happens the same visit instead of waiting a week on shipping. Call 540-300-3122 for the size you need. Equipment engines only — we don't work on cars.
