How to Achieve Low-Maintenance Garage Bucks

Garage bucks, the trim along which the garage door runs, are essential to proper garage door installation. With a thermal stop over the top with a rubber flange, the buck helps form the door’s seal. It’s also one of the most moisture-prone areas of the exterior and therefore requires special attention to materials and installation.

When installing the garage buck, it’s ideal for the trim to be flush with the ground to help minimize air intrusion and bugs. However, many trim materials, such as engineered wood, fiber cement, or wood, cannot be used in ground-contact applications due to moisture absorption.

This is evident in the replacement project pictured here. The original garage bucks were painted pine, which proved problematic. As shown in the image below, the bottom of the trim is nearly rotted away due to the wood wicking moisture from the ground. The homeowner also had to paint the trim each year, as moisture and movement caused the paint to flake off. In addition, the wood was more vulnerable to insects.

To remedy the issue, the installer removed the pine trim and added TruExterior 1×6 trimboards in its place. In an area this prone to moisture, TruExterior offers a reliable solution: It can be installed in contact with the ground, it is dimensionally stable, and it won’t crack, warp, or split. Made with a proprietary blend of polymers and fly ash, TruExterior Trim is also low maintenance and can be painted any color, including dark hues, while offering the authentic look of wood.
