About East Coast Diesel & MarineSomebody willing to come to the machine.
We are a mobile heavy equipment, diesel and marine repair outfit working out of St Johns,
Florida. Field service across fifteen towns, shop work when a job needs a roof, and a phone that gets
answered at 2am.
The machine stays where it is, if we can manage it.
Most repair businesses are built around a building. You bring them the machine,
they work on it when they get to it, you collect it. That works fine for a pickup truck and badly for a
thirty ton excavator sitting in the middle of a job that has a completion date on it.
So we built this the other way round. The truck goes to the machine with diagnostic gear, hose and
fittings, a welder, compressor, tooling, fluids and the parts that fail most often. Hydraulics, electrical,
cooling, fuel, brakes and a large share of engine work all get done where the machine sits.
There is shop capability for the jobs that genuinely need it, and this is where we are different from
outfits that will attempt anything anywhere: head gaskets, in frame rebuilds and full teardowns belong
under a roof on a clean bench. Doing that work in the sand produces a repair that fails twice, and we
would rather tell you no than sell you that.
Admitting a limit is the point. If we cannot get to you fast enough to do
any good, or the job is not one that should be done in the field, you will hear it on the first call.
That is worth more to you than an optimistic yes.
The shop, for the jobs that really do need a roof.
Whether we can help, roughly when, and whether the job belongs in the field or under a roof. Before anybody gets in a truck.
02
Diagnosis before parts
Pressures, codes, readings and live data. Buying parts on a hunch with somebody else's money is not diagnosis, it is gambling.
03
A number before the work
You get the cause and the cost before the repair starts, including the version where the honest answer is that it is not worth fixing.
04
Real parts and real torque specs
Assembled properly, to spec, with the fluids and filters the machine actually calls for.
05
Tested under load
A machine that idles fine in the yard is not repaired. It gets worked and watched before the truck leaves.
06
Told what failed and why
So you can watch for it, change how the machine gets run, or plan the next repair instead of being surprised by it.
How a call goes
How mobile equipment repair works.
STEP 01
You call
Tell us the machine, the symptom and where it sits. We ask a few questions so the right parts come with us.
STEP 02
We tell you straight
Field job or shop job, and roughly when we can be there. If we are too far out to help today, you hear it on the first call.
STEP 03
We diagnose on site
Pressures, codes, readings. You get the actual cause and a number before a wrench turns on the repair.
STEP 04
Back to work
We fix it, test it under load and clean up. You get told what failed and what to watch so it does not happen twice.
Questions we get
About the business.
Who is East Coast Diesel & Marine?
A mobile heavy equipment, diesel and marine repair business registered in Florida as East Coast Diesel & Marine, LLC and based in St Johns, on the St. Johns and Duval county line.
Are you a shop or a mobile service?
Both. Field service is the main thing we do, and there is shop capability for the jobs that genuinely need a roof and a lift. We tell you which one your job is before we start.
Why does the name say Marine?
Because we do marine diesel as well as land equipment. It is the same engine with raw water cooling and a wet exhaust, and boats around here get poorly served by shops that only do one or the other.
What areas do you cover?
Fifteen towns across eleven counties in Northeast Florida and Southeast Georgia. The service areas page lists all of them.
Do you publish your rates?
We give you the call out charge on the phone and the repair number before the work starts. Printing rates on a web page is how people end up quoted for a job nobody has looked at.
How do I get hold of you?
Call (904) 496-2937. The phone is answered around the clock. Email works for anything that is not urgent.
Machine down
Call it in and get a truck rolling.
Tell us the machine, the symptom and where it sits. If we can help, you will know on the first call. If we cannot get to you in time to do any good, we will say that too.
