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.

Generally, the height of your dog fence should be 3 times the distance from the ground to your dog’s shoulder. For most small breeds, a 4-foot high fence will be more than enough to keep them from jumping out. Medium-sized breeds like Golden Retrievers, Labradors, and German Shepherds will need at least a 5-6 foot fence to stay contained. Large breeds that are also excellent jumpers, such as Greyhounds, may need a 7-foot high fence. 

How long a fence lasts, including a split rail fence, will depend on the material from which it’s made. The average lifespan of a wood fence is about 15 to 20 years. However, split rail fences made out of premium materials, like composite, vinyl, steel, or aluminum, can last for 25 to 30 years or more, especially if you take good care of the material and carry out necessary maintenance.

The average cost to install a wrought iron fence is around $3,150, with typical project costs ranging from $470 to $10,500. The final price can vary significantly based on several factors, including the fence's total length and height, design complexity, metal thickness, and your property's topography.

For materials alone, you can expect to pay around $25 to $35 per linear foot. When including installation, the cost is typically between $50 and $70 per linear foot.

Additional factors that can influence the total cost include:

• Custom designs, decorative flourishes, gates, and columns

• Labor costs in your area

• The need for permits

• Land preparation, such as old fence removal, tree or bush clearing, and land grading

For an accurate estimate, it is best to consult a professional fence installer with the specific measurements and design requirements for your project.
