When considering how much of a gap should be under a fence or gate, a good rule of thumb is to keep gaps between 2 and 5 inches tall. This allows for some ground clearance for the gate but still provides safety for children and pets, who shouldn’t be able to squeeze through a gap of that size.

Galvanized metal, vinyl, and composite fences are known to be the longest-lasting options, often surviving for over 30 years with proper care. Metal fences, including galvanized chain link and aluminum, can look great for decades because the galvanization process adds a protective coating that resists weather and pests. Similarly, vinyl and composite materials are resistant to pests and can withstand harsh weather for many years. In comparison, a typical wood fence lasts about 15 years, and a standard vinyl fence has a lifespan of 20 to 30 years.

Glass has one of the longest lifespans of any fencing materials, lasting anywhere from 10 to 30 years on average. Just how long your glass fence lasts depends on several factors, including how well you maintain your fence, the climate, and the type of glass you use. 

If you live somewhere with severe weather like hail, tornadoes, or hurricanes, expect your glass to have a shorter lifespan. Pool glass is one of the thickest tempered glass materials and may last longer than other options—especially compared to laminated glass.

Regular maintenance for wire fencing includes annual inspections for rust or damage, tension adjustments every two to three years, and immediate repair of any breaks or loose sections. You should also regularly check the fence posts for stability, particularly after severe weather, and make sure to remove any vegetation growing along the fence line.
