How Much Does It Cost to Build a Trellis?

A trellis costs between $60 and $350 per linear foot, with most people paying around $200 per linear foot, including installation. The price per foot varies a lot based on the height of the trellis panel, the material, shape, and design you choose, and whether you choose prefabricated or custom models.

Average Cost to Build a Trellis

The cost of materials makes up about 75% of the total project cost, assuming you're using prefabricated trellis panels. The cost of materials varies significantly, from $45 to $260 per linear foot. Metal trellises usually fall at the lower end of the cost range, with high-quality vinyl and wooden models being at the upper end.

Trellis Installation Costs

Labor accounts for around 25% of a trellis installation project. If you hire a local handyperson to install your trellis, you'll pay around $60 to $125 per hour. If you hire a nearby landscaper, expect to pay $50 to $150 per hour for landscaping costs. Typically, it takes up to 2 hours per 8-foot trellis section, although this will vary based on trellis material, accessibility, and ease of installation.

Trellis Cost by Size

The price you pay for trellis installation is significantly impacted by the size of trellis you choose. Although generally measured in linear feet, like in the table below, trellises also vary in price based on their height, hence the extensive cost range for each panel size listed below.

Cost to Build a Trellis by Material

The price of materials ranges from $44 to $144 per linear foot and determines your trellis project price. Metals, like stainless steel and iron tend to be the least expensive. At the upper end of the range, you'll find vinyl and wood trellises. Take a look at some common trellis materials and their typical costs.

Trellis Cost by Shape

With costs ranging from $150 to $950, the shape of your trellis plays a role in how much you'll pay based on the complexity of the shape and the amount of material used to create it. Simpler shapes with straight lines tend to be less expensive than complex, curved, and arched designs. The table below shows you some popular trellis shapes and their typical costs.

Factors That Impact the Cost of Trellis Installation

Aside from the type of trellis, what it's made from, and where you're installing it, there are a number of other factors that influence the final project price. 

Plants

Most homeowners use a trellis to support plant growth, regardless of other functions. And many people like to have the area planted at the same time as the trellis is installed. Alternatively, you can hire a local gardener to plant up the trellis for you after installation. Remember to budget for planting when planning your project. Common plants for trellises include:

• Honeysuckle:  $10–$15

• Mandevilla: $10–$18

• Bittersweet: $10–$20

• Climbing rose: $15–$30

• Bougainvillea: $15–$30

• Morning glory: $15–$30

• Boston ivy: $25–$40

• Dutchman's pipe: $30–$60

Painting or Sealing

Painting or sealing a trellis costs between $40 and $100, including tools, equipment, and paint. Over time, constant exposure to the weather can cause fading, rot, rust, and other damage to your trellis if you don't provide some regular maintenance. Painting or sealing it is the best way to keep it in tip-top condition. 

Trellis Upgrades

Trellis upgrades enhance the appearance of your outdoor space but will cost you extra. Installing a water feature, for example, enhances the aesthetic of your garden and attracts birds and small animals. To combine a trellis and a water feature, you'll also need to carefully consider what plants will thrive in the wetter conditions.

Other enhancements can include adding stained glass to the spaces between the trellis lattice and adding accent lighting.

Adding an Arbor

If you want to add a cover or roof to your trellis, an arbor is the way to go. Remember to budget $300 to $1,000 to cover the cost to build an arbor. Arbors provide shade, shelter, and an interesting design aesthetic. It also creates a beautiful green and floral canopy as your plants grow and mature. 

DIY vs. Professional Trellis Installation

If you're investing a significant amount of money in a high-quality trellis that requires anchoring securely, it makes sense to hire a professional. However, if you have all the necessary tools and the right skillset, installing a trellis is something you can do yourself. 

However, for the sake of safety and longevity, it's often better to leave it to the pros.
