Why vinyl
Vinyl (PVC) fencing doesn't rot, doesn't need painting, and cleans up with a hose. It comes in privacy, semi-privacy, picket and ranch-rail styles, in several colors and textures. For homeowners who want a clean look with little maintenance, it's a popular choice.
Quality differences
Not all vinyl fencing is the same. Better products have thicker walls, UV inhibitors to resist yellowing and brittleness, and reinforced rails. Thin, low-quality vinyl can sag, crack or blow out in wind. Ask the installer about the product's wall thickness, whether rails are reinforced, and what the manufacturer's warranty covers.
Posts and reinforcement
Vinyl posts are hollow. They're typically set in concrete, and gate posts and posts in windy areas are often reinforced with a steel or aluminum insert or filled with concrete. Gates need especially sturdy posts, because vinyl gates can sag if the hinge post moves. Bottom rails on long sections may have aluminum stiffeners to prevent sagging.
Heat and cold
Vinyl expands in heat and contracts in cold. Rails are designed to slide in post holes to allow movement; an installation that locks everything tight can buckle. In very cold weather, vinyl becomes more brittle and can crack if hit, for example by a lawnmower, a thrown ball or a vehicle. Dark-colored vinyl absorbs more heat and may be more prone to distortion in very hot, sunny spots.
Wind
Solid vinyl privacy fences catch the wind like a sail. In windy areas, ask about semi-privacy styles that let some air through, reinforced posts, and closer post spacing. A properly installed fence should handle typical local winds.
Cleaning and repairs
Clean vinyl with a garden hose, soft brush and mild soap. Avoid abrasive cleaners that dull the finish. Damaged panels or rails can usually be replaced individually, but colors can fade over time, so a new piece may not match exactly. Ask whether the manufacturer offers replacement parts for the style you choose.
Property lines and permits
Confirm property lines before building; a survey helps if markers are unclear. Check height limits and permit requirements with your city or county, and any homeowners association rules.
Questions to ask
- What brand and product line will you install, and what's the wall thickness?
- Will gate posts and posts in windy spots be reinforced?
- How do you allow for expansion and contraction?
- What does the manufacturer's warranty cover, and is it transferable?
- Will you call in a utility locate before digging?
- Is a permit required, and who obtains it?
Slopes and uneven ground
Vinyl panels are rigid, so on sloped yards they're usually stepped: each panel sits level and steps down from the one above, leaving a triangular gap underneath at the low end. Some products can be racked to follow gentle slopes. If you need the bottom closed for pets, ask how the installer will handle gaps on a slope.
Gates
Vinyl gates should have a metal frame or internal reinforcement, heavy-duty self-closing hinges and a latch rated for outdoor use. Wide gates may need a wheel or a drop rod to hold them in place. Ask what the gate warranty covers, since gates see the most wear.
Color choices
White, tan and gray are common, and textured wood-grain finishes are available. Lighter colors stay cooler in the sun and show less fading. Darker colors look rich but can show heat distortion in very sunny spots on some products.
Neighbors and the good side
Many vinyl privacy styles look the same on both sides, which avoids the question of which neighbor gets the good side. Talk to neighbors before building on a shared line.
