Picket Fence Costs & Cost of Installation. You might want to start by considering the material you use for your fencing. For a traditional white picket fence, wood is the most obvious choice, but vinyl is growing in popularity. Wood costs less, with a wood picket fence price of $10-$14 per linear foot installed. The vinyl picket fence price will be closer to $20 per linear foot installed. For a painted fence, you can find it pre-painted in white or you can paint it yourself.
