What this covers
Composite fencing uses boards made of wood fiber and plastic, the same material as composite decking, usually set between aluminum or steel posts. It does not rot, splinter or need staining, and it is often installed horizontally for a modern look. The installer sets the posts in concrete at the manufacturer's spacing, fits the bottom rail or channel, slides the boards in with the recommended expansion gaps, and finishes with a top cap. Composite is heavier than wood and moves with temperature, so posts must be plumb and well-footed and the boards left room to expand. Clean work shows in level courses and even gaps along the whole run.
When to call
- A contemporary home or backyard that wants horizontal lines and a dark finish.

Questions people ask
Does composite fencing fade?
Capped composite boards resist fading and staining well. Uncapped boards weather slightly in the first months and then hold their color.
Why metal posts instead of wood?
Composite boards are heavy and posts carry the load. Aluminum or steel posts stay straight, do not rot at the ground and give a consistent look with the boards.
Can composite be used for gates?
Yes, on a metal frame so the gate stays square. Composite alone sags, so the installer builds a welded or bolted frame and clads it.
