How to Attach a Trellis Fence Topper

A fence topper trellis is a panel installed on a fence at the top panels to enhance its design. Often featuring a lattice or grid-like pattern, a trellis topper is designed to allow light and air through while adding a decorative and functional element. It can improve privacy by reducing visibility over the fence, supporting climbing plants, and adding architectural interest to an outdoor space. 

Trellis fence toppers are versatile and are generally available in various materials, such as wood, metal, and plastic. Plastic trellis toppers, like those from EnviroBuild, are particularly popular because they are durable and low-maintenance, making them ideal for long-lasting installations.

Before attaching your trellis topper, ensure that your composite fence is correctly installed and level. EnviroBuild’s composite fence posts are durable and resistant to rot, making them a stable base for trellis attachments. Clear the work area around the fence and gather necessary tools such as a drill, screws, and post caps and confirm that your trellis panel fits the dimensions of the fence you’re working with.

1. Follow the standard EnviroBuild

fencing installation guide up to the point where you would begin sliding fence panels into the posts.

2. Insert ten fence panels between the posts.

3. Place the cap on top of the tenth panel, making sure to attach the fence clips at the cap’s ends.

4. With the cap secured, simply slide the trellis into place on top of the fence panels.

5. If using composite posts, add post caps as directed in the fencing installation guide.

Attaching a trellis fence topper to your EnviroBuild composite fence is an excellent way to elevate your outdoor space’s appearance and functionality. By following the steps above, you can achieve a sturdy and aesthetically pleasing setup. Regular maintenance will ensure that your trellis remains a beautiful and lasting feature in your garden.

EnviroBuild products require minimal maintenance, but occasional care can keep them looking their best over time. To keep EnviroBuild composite products free of dirt, grime, and mildew, it’s best to maintain a clean, dry surface with regular cleaning. Although EnviroBuild products are designed to resist mildew and staining, mildew may still form in areas exposed to moisture, dirt, or pollen. Periodic cleaning will help keep surfaces looking fresh and reduce build-up.

For cleaning EnviroBuild composite fencing and plastic trellis toppers, use soapy water with a soft-bristled brush or a power washer set to a maximum of 1500 psi. Be sure to spray along the grain direction of the fence and keep the nozzle at least 6 inches from the surface. A fan tip nozzle and appropriate cleaning products will help ensure effective, gentle cleaning.

Surface scratches and scuffs on EnviroBuild composite fence products typically fade over time as the material weathers. For immediate scratch removal, use a wire brush or coarse sandpaper (60-80 grit) on the Pioneer range, brushing in the direction of the grain until the mark is removed. The sanded area should blend naturally within 8–10 weeks as it weathers with exposure.

EnviroBuild trellis fence toppers are made from plastic, so there is no need to worry about them staining. All our trellis toppers are also black, so in the unlikely event that something is spilled on them, it won’t be evident at all.
