I know of a good contractor in Johor Bahru. My girlfriend's dad is a developer and even they use them for minor renovations. So PM me if you are interested.

Hi all Johorean,
I'm new here ... just want to gather some information and exchange experience .
is there anybody who owns a property in Setia Eco Garden ?

If yes do you have  got good Contractor to introduce ?
I'm currently in the midst of surveying ...

generally avoid calling contractors who put their namecard / pamplet in your letterbox.
As for those who approach u in person, 50% are vultures, 50% are sincere,
if u mean a polite person selling their services to you, try to check for recommendations
online. if dun have, u may rather rely on actual recommendation from ppl like relatives,
best frens, or even lowyat.

But take recommendation at a pinch of salt. contractors sometimes have mood swing also.

setia eco garden is rather nice, but very far 
i can introduce you contractor, quite a few lowyat guys already approach him, and i think
2-3 ppl already engaged him to do work already. Always rem, if you don't like the contractor
way of presenting to you, avoid them then.
