Repair wood fences and gates

Task: Cycles of cold and wet weather cause wood to move, twist, and warp. That can make garden gates fall out of alignment, and can cause fence pickets to loosen or fall off. Check for signs of loose fencing, and fix sagging gates.

Shortcuts: A cordless battery-powered nail gun ($250) makes quick work of refastening pickets and fence supports. Use only galvanized nails for outdoor work. Use a power drill fitted with a screw tip or a hex driver to remove or tighten loose screws and bolts in gates.
