What Are the Best Materials for Exterior Trim in Wilmington’s Climate?

calander Aug 21 , 2025 user-iconAnderson Painting

Wilmington has a unique coastal climate. During the summer, the weather becomes hot and humid, often resulting in thunderstorms. Winters tend to be mild, with the occasional cold front. What this means for your Wilmington home is that you must ensure the exterior trim can handle the temperature fluctuations. It must also be able to withstand constant moisture, intense UV rays, and salt air.

Fortunately, there are several options available for exterior trim materials that suit Wilmington homes.

Best Wilmington Weather-Ready Exterior Trim

When choosing an updated trim for your house, consider the following:

1. Fiber Cement Trim

This type of material can protect your home against moisture, rot, pests, and even fire. Fiber cement mimics the look of wood but stays much stronger in humid coastal conditions. Builders throughout North Carolina utilize fiber cement due to its durability and low maintenance requirements.

In Wilmington, fiber cement is at the top of the list of best exterior trim materials because of its stability and long lifespan.

2. Cellular PVC Trim

Another great option for exterior trim is cellular PVC. This material can help your home eliminate excess moisture and resist insects. It is also very durable, requiring almost no maintenance. Cellular PVC may expand slightly when exposed to high temperatures, but it is easy to work with and paint on.

Even though Wilmington can get very hot in the summer, this trim option is a smart and reliable choice.

3. Engineered Wood Trim

Engineered wood trim consists of wood fibers and resin. The result is an exterior trim material that resembles real wood but costs less. However, while this is a beautiful option, it requires regular maintenance. If you are willing to check your trim for damage and reapply sealant frequently, it may be a good choice. Engineered wood trim can swell if not properly sealed, so keeping up with maintenance is crucial.

4. Traditional Wood Trim

Wood trim is a popular choice for historic homes. It provides a classic, charming look that appeals to many. The problem with traditional wood is that it requires significant maintenance, especially when used in coastal areas. Salt and dampness can cause considerable wood damage if not regularly maintained.

5. PVC-Aluminum or Vinyl Capping

You can add aluminum or vinyl cladding over wood trim (window capping). Doing this helps protect against the weather while hiding aging paint. It also reduces the need for frequent repainting. This option works well for exterior window trim material, especially if you want to preserve heritage wood underneath.
