Alle englischen Vorschläge im LEO für "Mechaniker"? Hilft Dir das vielleicht?

http://www.thefreedictionary.com/artisan

Artisan - A skilled manual worker; a craftsperson.

Dazu fällt mir nur noch
workmen
ein.. und dann hast du wieder das Problem mit "man"

If you can't use the actual profession (plumbers, carpenters etc) then maybe you could use
contractor, workers, workmen (although this has men - are there workpeople??)
Sympathies - this is one of those terms I hate trying to translate

maintenance workers?

Blue collar worker/employee???

Dictionary: arbeitskraft

just a thought ;)

And possibly a little less known...

Artificer
- A skilled worker; a craftsperson.
- One that contrives, devises, or constructs something:

if it's to do with revamping your house, where in German you'd say "wir haben die nächsten 4 Wochen die Handwerker im Haus", wouldn't the English just say "builders", even if there might be plumbers, carpenters, electricians and decorators amongst them, too?

*grummel* One of these days I'm going to learn to read the context.
:(

jack of all trades - a man skilled in various odd jobs and other small tasks
Maybe ?

Yes, we do tend to say 'we had the builders in', and other equally vague comments :-) Probably as the 'builders' are not necessarily properly trained in anything!

In this case I'm doing a website for a company that makes and sells tools for DIY enthusiasts and handymen. Maybe artisans and craftspeople go there, too, but there's a big picture of a meaty bloke in an overall which would clash with any artsy description. One "Handwerker" I'm having special trouble with is actually a "Handwerkertheke" you can go to if you have questions about the tools. Maybe I'll just go for "workman" after all - I just like to avoid using these words ending in "man" if possible. Useless language, English!

have you checked the B&Q website for how they put it? Or any other British DYI chains - such as there are?

expert counter?

Perhaps professionals would work in some cases, eg
Our amazing range of tools will delight professionals and DIY enthusiasts alike 
or whatever.

Would help desk be too simple for your "Handwerkertheke"?
