Fencing and decking are one of those jobs that can look great when it's new, but the true test is will it withstand winds and extreme moisture. At Buildtec-X we make sure only exterior certified grade timber is used. Most certified timber has a warranty for 15 years. It's not long, but with concrete posts and gravel boards you can push you fencing structure up to 25years; you only have to replace panels. All our posts are concreted into the ground.
