No offense but I find that hard to believe since you keep posting your website.
Mine still looks good and I've only painted one side using a thin cheap fence paint. Mind you it's only four years old so far.
That's a load of crap. You should get 20 years out of a paling fence. I got 25 years out of my Hwd back fence and I could have gotten a few more if I'd replaced a few palings, whacked in a couple of star pegs, and thrown a coat of sump oil on it to make it look uniform again. The neighbour had to go halves so I thought it would be better just to get him to spring for most of the gear and do the labour myself, then not worry about it for another 20 years. ;)
20 years ago timber fencing was made from much thicker palings and they were made from hardwood, todays fencing is made from young pine and is only 10mm thick. this is why you dont get as long a life. Grant you some fencing may last longer than 7-10 years they may also be in the shade most of the time. We ourselves have pulled down fencing that is only 7 year old because it hadnt been looked after, things such as letting water pool around posts and painting one side contributed to the short life span. more realistically you should see 15 years, again it would also depend on if you have either redgum/pine or even concrete or steel posts for your timber fence. just a note we install colorbond fencing for $58.00 a meter and timber 6 for $49.00 a meter. no where near double the price. The $70.00 was probabily for 2.1m high colorbond fencing.
we keep posting the site as we have a lot of valuable information on it, such as tips on how to look after your fence, pool fence regulations, and installation downloads as well as colour charts and help if you have problems with neigbours. We only install locally to Western Melbourne and we already have extensive advertising so the occasional one or 2 people from this website wont make me rich by any means.

Also from your website, starting @ $70/m colorbond is over double the price of a 6' paling jobbie.
