We've recently moved and would like to increase the height of one side of our fence to 6 foot panels for more privacy - they are currently 5 feet panels (it's our fence). Obviously the existing concrete posts will be shorter with the new panels - I'm aware that you can buy post extenders but do these look a bit naff? Has anyone done this? I assume you'd then need to repaint the lot so it all blends in. We don't want to pay out for new taller posts. Thanks
