Why YOUR Trim Board Decision Matters
Trim boards do more than frame a window or polish off a porch post. They’re part of the first impression your project makes. The wrong material can lead to early failure, warped boards, or a look that just doesn’t fit the style you’re going for. The right material stands the test of time, resisting the elements, holding paint, and staying straight so your craftsmanship shines for decades.

PVC Trim Boards – The Good, the Bad, and the Plastic
PVC trim boards have earned a spot in the market for certain applications, especially where moisture is a major concern. But it’s not all smooth sailing. Let’s take a closer look.
PVC Pros
- Low Maintenance – No frequent repainting.
- 100% Waterproof – Ideal for ground contact or extreme moisture conditions.
- Lightweight – Easier to handle, especially on tall installs.
- Insect Proof – Bugs aren’t interested in chewing on it.
PVC Cons
- Thermal Expansion & Contraction – Changes in temperature cause the material to expand and contract, which can lead to gaps or buckling if not installed to manufacturer’s instructions.
- Higher Cost – Expect to pay more up front.
- Workability Issues – Doesn’t cut, shape, or fasten like wood; requires different tools and techniques.
- Environmental Concerns – PVC isn’t biodegradable and has a bigger environmental footprint.
- Aesthetic Limitations – It often looks like plastic, which can clash with the natural wood look many projects demand.

As wood cannot sit in water, and proper moisture management is key, the following clearances need to be used for exterior installation: INSTALL 6″ ABOVE GRADE, Trim should be installed always at least 6” from ground. INSTALL 2″ ABOVE FLAT SURFACES, 2” breaks are crucial on the roof and flat surfaces (porches, decks, etc.) INSTALL 1/4″ ABOVE FLASHING, Flashing is an imperative; and always maintain a 1/4” gap for a capillary break.
The Real-World Considerations
While PVC is a solid choice for certain applications like docks, direct ground contact, or areas with extreme moisture. Many builders prefer WindsorONE for most exterior and interior trim work because of its authentic look, workability, and long-term stability.
PVC might save you a step in waterproofing, but WindsorONE offers a better return on investment when you factor in performance, aesthetics, and installation ease.
