Mile High Food Trucks repairs food trucks and food trailers at our shop at 3895 E 45th Ave in Denver. We build food trucks for a living, so we work on both halves of the truck: the vehicle underneath and the commercial kitchen inside. Call 720-209-2653, tell us what the truck is doing, and we will book you in.
Most mechanics will not touch a fryer or a suppression system, and most appliance techs will not crawl under a step van. That is why Denver operators end up with a truck sitting for two weeks while three different shops point at each other. We diagnose the whole truck in one visit and give you a written estimate, with parts and labor separated, before any work starts.
What we repair
- Power: generators that surge or stall under load, inverters and shore power inlets, breakers that trip when the fryer and the fridge cycle together, battery banks on all electric trucks
- Propane: regulators, leaking fittings, worn flex lines, appliances that burn yellow or will not hold a flame, high altitude orifice changes
- Water and plumbing: pumps, water heaters, fresh and grey tanks, three compartment and hand sinks, split lines after a freeze
- Refrigeration: reach ins and prep tables that cannot hold 41 degrees in July, condensers, poor airflow, undersized units
- Hood and fire suppression: exhaust fans, baffles, fusible links, nozzle coverage after the cook line has been rearranged, expired tags
- Cooking equipment: griddles, fryers, ranges, ovens and steam tables
- The vehicle: brakes, suspension, cooling and exhaust on step vans and box trucks
- Trailers: frames, axles, bearings, couplers, jacks, brakes and lights
Inspection and compliance work, same visit
Most trucks that come in for a repair also need paperwork before they can work again, so we do both at once. An LP gas pressure test is $350, with the documentation the fire inspector wants to see. A fire suppression inspection is $300: we check nozzle coverage against your current cook line, replace fusible links and retag the system, or tell you plainly if it is an older system that needs replacing rather than servicing. Hood cleaning is quoted by hood size.
Since 1 January 2026, a Colorado fire permit issued under the current fire code by a certified inspector is valid statewide, as long as you send a copy to each local fire authority before you operate there. That makes getting the truck right once, with clean paperwork, worth more than it used to be.
What Denver does to a food truck
At 5,280 feet, gas appliances lose output and generators derate, so a truck built for Texas or California often runs cool and trips breakers here until it is adjusted. Refrigeration works harder in thin air, especially in a truck with no airflow behind the units. Winter is the other half: water lines split and pumps crack on trucks parked with water in them, and road salt and magnesium chloride from I-70 work on brake lines and frames. We can add tank heaters and insulate exposed lines, which costs far less than replacing a pump and a water heater every spring.
Denver’s propane rules are stricter than the national code, so trucks moving here from other cities often need gas work before they can get a Denver permit. If you are bringing a used truck in from out of state, have it looked over before you book your first event.
When a repair becomes a rebuild
Some trucks come in with a list of small problems that are really one big one: the truck was never built to code. Hand sinks fed by a foot pump, water jugs instead of tanks, no suppression over the cook line, propane cylinders inside the kitchen. Those are not repairs, and we will not pretend they are. We will price a proper refit of the systems that fail, using the same parts we put in a new build, or tell you straight if the vehicle is not worth that money.
How a repair visit works
Call 720-209-2653 and describe what the truck is doing, when it started and whether an inspector has flagged it. If we can talk you through it on the phone, we will. If not, we book a time, look the truck over at the shop and give you a written estimate before we start. Trucks that will not start and trailers that cannot be towed are handled case by case, so tell us on the call.
Frequently asked questions
Where is your food truck repair shop in Denver?
3895 E 45th Ave, Suite E, Denver, CO 80216. We are open Monday to Friday 9:30 am to 5:30 pm and Saturday 9:30 am to 3:30 pm. Call 720-209-2653 to book a time so the right technician and parts are here when you arrive.
Do you repair food trucks you did not build?
Yes. A lot of our repair work is on trucks and trailers built by other shops, including trucks bought used from out of state. Every food truck is the same handful of systems, and we build all of them from scratch every week.
Can you fix the reason my truck failed a Denver inspection?
Usually, yes. Bring the inspector’s report. The most common failures we see are propane, hood and suppression, and hand sink plumbing, and we handle all three in house.
How much is an LP gas pressure test in Denver?
$350. We test the system at operating pressure, check every joint, and give you the documentation Denver Fire and other departments ask for. A fire suppression inspection is $300.
Do you repair food trailers too?
Yes: frames, axles, bearings, couplers, jacks, brakes and lights, plus everything in the kitchen.
Do you repair the vehicle as well as the kitchen?
Yes. Brakes, suspension, cooling and exhaust on step vans and box trucks, and the generator, electrical, plumbing, propane, refrigeration and cooking equipment in the kitchen, so you are not running between a mechanic and an appliance tech.
