Naples weather is hard on a fence. Coastal wind, salt air, and summer rain all find a weak build fast, so we set posts deep, keep the runs straight, and fasten everything the way the manufacturer says to. Our own crew does the work, not a sub we met last week. Most vinyl privacy fences run about 125 feet and land around $3,500, with 3 to 5 weeks from signing, depending on how fast your HOA and the county move. Financing through Wells Fargo is available, including 0% interest.
