When your rolls of silt fence join together, you’ll want to overlap them to make sure they’re still as effective at keeping water out without requiring fastening together. Overlap two sections of the silt fencing so that two sheets of fabric cover the span of two posts. If you want to fasten them together, you can staple them or use a zip tie, depending on whether your posts are metal or wood. 

In most cases, you will need a building permit to put up a vinyl fence, especially if the fence is sitting on or close to your property line. You can ask your local building department or  fence installation company if your fence project will require a permit. If so, you can expect it to cost between $20 and $60. Your fence installer should pull the permit for you. Building without a permit could eventually require you to pay again to remove the fence and reinstall it after getting the job approved.

Since wood is weaker when installed horizontally versus vertically, a horizontal fence is prone to sagging. You can prevent this drooping from happening by building a sturdier fence. Use softwoods that are more stable, such as cedar and redwood, or denser hardwoods for your fence materials. If you can’t afford these pricey materials, use thicker two-by-six pressure-treated pine boards or shorten the span the fence boards have to cover by installing more posts.

A high-quality wrought iron fence is one of the most durable options available and can last a lifetime, or even centuries, with proper care. However, wrought iron is susceptible to rust and corrosion if not maintained.

To maximize its lifespan, regular maintenance is required. This includes:

• Cleaning the fence with soapy water every six months.

• Scrubbing away any rust or corrosion as soon as it appears.

• Applying a new coat of paint or refinishing the fence every few years to protect the metal from moisture and oxygen. The recommended frequency varies, with sources suggesting anywhere from every 1 to 10 years.

If significant rust develops, it's wise to hire a professional fence repair company to clean the rust and reseal the fence. The cost to refinish a fence is typically between $5 and $12 per square foot, a worthwhile investment to ensure its longevity.
