When it comes down to wood, composite, or vinyl post caps, Vinyl Solutions Unlimited stands by vinyl! Why?

Wood has obvious downsides, like rotting and having to stain every year to keep your deck or decks looking brand new. Composites are good until you scratch the vinyl outside layer of your deck board, fence post, railing post, or vinyl cap. Since many composite posts, deck boards, and post caps have wood filler, that scratch can then lead to moisture getting in the material and slowly rotting, and reducing the strength and looks of the product that will later need to be replaced over time.

Products with 100% vinyl will not rot! These vinyl posts, deck boards, and post caps do not have a wood filler, so rotting is not an issue. We have vinyl fences and decks that we installed our first year in business, in 1997, that still look great! Vinyl is the choice in today's market!
