Durable, Maintenance-Free Style
If you love the classic look of wood but want to skip the upkeep, our Azek composite post caps are the perfect solution. Crafted from 100% genuine Azek material, these caps are built to last for decades without rotting, splitting, or attracting insects. Azek is completely impervious to water and pests, eliminating the two biggest causes of wood post deterioration.
Every Azek post cap is cut and milled just like our premium wood post caps, giving them the same authentic profile and style. In fact, most people can’t tell the difference by sight—they look just like freshly painted white wood caps, but without the need for sanding, sealing, or constant repainting.
Custom Sizes at No Extra Cost
We stock standard sizes in nominal and true 4x4, 5x5, 6x6, 7x7, and 8x8 dimensions. Larger sizes, such as 10x10 or more, are also available by request. Simply choose the next size up from your post, then note your exact measurements at checkout—we’ll custom cut your cap with an additional 1/8" opening for a perfect fit.
Paintable for a Personalized Look
Azek post caps arrive in their natural white finish but can be painted any color using high-quality latex paint. This not only seals the precision-cut edges but also ensures maximum longevity. Unlike wood, Azek holds paint exceptionally well—you won’t need to touch it up for years, if ever.
Whether you’re topping deck posts, fence posts, or porch columns, Azek composite post caps provide a timeless design, unbeatable weather resistance, and true maintenance-free performance. If you want to add nighttime curb appeal, consider pairing them with our solar post caps for a perfect combination of style and function.
