Fencing questions, answered by experts

A fence post set in concrete lasts anywhere from five to over 25 years, depending on how well the concrete was applied and the fence post’s material. Untreated wood posts in concrete could last less than 10 years, but a durable, treated wood set in properly applied concrete could last a few decades. However, all fence posts will wear out eventually, so expect to need to replace your fence post every five to 15 years.

There are many pros and cons to vinyl and composite fencing. Both fencing types offer longer lifespans than wood fencing, with some notable advantages. Whether one is better for you will depend on a few factors. Composite is better if you prefer recycled materials, while vinyl is extremely easy to clean. 

Also, consider the disadvantages: vinyl can be more expensive, while composite fencing fades during the first six months.

While power washing isn't a requirement before you stain a fence, it can make the job much easier and faster while reducing manual labor requirements. The stain will not work if the wood is full of dirt and dust, so power washing, sometimes called pressure washing, is a fast and effective way to prepare the wood for staining. Remember that you need to stain or repaint relatively soon after the wood has dried so that there isn’t time for dust and dirt to build up again. 

Silt fences are very effective when installed correctly and used in proper locations. However, there are places where they don’t work as well. This includes property with a concentrated water flow, where runoff could pool or cause a flooding hazard. You’ll also want to use caution when installing in areas susceptible to landslides. Your contractor will follow state guidelines and know when an alternate solution is more effective.

While most homeowners aren't required to tell their neighbors that they’re putting up a fence, it's certainly a good idea to do so. Not only is it considerate to give neighbors a heads up about construction noise, but building a fence may limit your neighbors' access to their own backyards while building is taking place.
