Wood Deck Post Caps
Nantucket wood post cedar caps are decorative and protective wooden covers designed to fit over the tops of fence or deck posts. They’re commonly used in outdoor building projects to enhance the look of railings, pergolas, fences, and other structures while helping protect the end grain of the posts from water damage. Here’s a breakdown of what they are and what to consider:

Material: Cedar
- Western Red Cedar is a popular choice for post caps because it’s naturally rot-resistant, lightweight, and stable.
- Cedar holds up well outdoors, resisting moisture and pests better than many other softwoods.
- Over time cedar weathers to a natural gray if left unfinished, giving a classic coastal look.
Style & Function
- Finial Caps: Some cedar post caps, like the one in your image, have a rounded or sculpted finial on top — decorative and traditional in style.
- Flat or Pyramid Caps: Other styles include simple flat tops or pitched/pyramid shapes that help shed water.
- Sizes: Many available to sizes that will fit most posts.
Purpose
Protection:
- Post caps shield the top of a vertical post from rain soaking directly into the end grain, which is particularly vulnerable to rot.
Aesthetics:
- Adds a finished, polished look to decks, fences, and railings.
- Finials and decorative shapes contribute to architectural style — from classic to contemporary.
Finishes
- Unfinished Cedar: Natural look that ages gracefully to gray.
- Stained or Sealed: Enhances color and extends service life — recommended if you want long-term durability.
- Painted: Can be painted any color to match trim or railing — as you asked earlier about making it white.
Maintenance Tips
- Apply a sealer or exterior stain soon after installation to slow graying and protect the wood.
- Reapply finish every 1–3 years depending on exposure and desired appearance.
- Replace cracked or severely weathered caps to protect the posts.
