This depends mainly on how well the posts were installed and what type of wood was used to build the gate in the first place. Softwoods have a life expectancy of up to 15 years but can last slightly longer with regular maintenance and waterproofing treatments. By contrast, hardwoods can last up to 30 years with little care, so you may avoid costly replacements by spending a little more upfront.

Do you need a permit to build a fence if you are simply replacing an existing fence? Whether you need a permit in this case depends on your local laws and regulations. Most municipalities consider a fence replacement project as being equal to building a new fence, so you likely will need a permit. Check with your local building inspection department or zoning department to see if you need a permit. If you hire a local fence contractor, this pro can take care of obtaining all permits for you.

The lifespan of a picket fence largely depends on its material. Wooden picket fences typically last 10 to 15 years with regular maintenance, while vinyl and composite picket fences can last 20 to 30 years or more due to their resistance to weather, rot, and pests. Metal picket fences often exceed 30 years, especially when properly coated to prevent rust or corrosion.

You should stain both sides of your fence to get the full benefits. Fences often fall along property lines, so you may want to save a buck by leaving your neighbor’s side in the dust. If you do that, all you get is a slightly better view. Moisture and UV rays can still sneak in through the side that’s unpainted or worn down and damage your fence. Rot and rust will spread, even if you can’t see it from your side of the lawn.
