We used JD about 5 or 6 years ago. We found them to be very punctual, to quote quite low rates relative to other providers, and to get the job done fairly quickly. The downside was that some of the contractors were a little bit sloppy with their work - leaving holes in the wall, failing to provide a proper base for an external airconditioning unit, and over time it has become apparent that some of the wiring was a little bit dodgy because we get some strange problems with our lights and light switches (there is no evidence to say that this is poor electrician work - it could be that crappy components were used). However, with appropriate oversight, I think these guys are very good value and this is a real bonus considering how expensive large electrical contracts can be.

Approximate cost: $3000
