Some wooden fences may take a year or two before they warp and twist. With
others it can happen inside a few months. The fact is, sooner or later New
Zealand's weather will warp and twist out of shape timber post and rail
fences.
The good news is this won't happen with Fencing Around Same-Both-Sides steel
fences. You and your neighbours can be assured of a fence that with little
or no maintenance will stay straight and true and keep its stylish good
looks for years and years. Another negative about wooden fences! Instead of
adding value, warps and twists are a real put off for potential homebuyers.
