Pergolas vs Wooden Gazebos, Trellises & Arbors

In the consumer world, pergolas are often mistakenly referred to as gazebos, trellises and arbors. At O’Neill’s Green Services, our knowledgeable staff will take the time to make sure that you know exactly what you are purchasing, so that you are 100% satisfied with your investment.


Free standing structures that have been historically built of wood, although aluminum products like Alumawood are quickly rising in popularity, due to their durability and classic cedar wood appearance. Pergola designs vary, however they all have posts or columns that generally support flat roofs with slats or beams (also known as lattice) running across them, which allow filtered sunlight to shine through. Aluminum pergolas can have a lattice or a solid roof that will provide full protection from the elements, which allows for year-round use. They are most commonly built over walkways where partial shade is desired, but are also used to create transition zones and eye-catching entryways to garden areas. At O’Neill’s Green Services, we only install Elitewood’s Classic Cedar aluminum products, to ensure you get the longest enjoyment from your investment, with little to no maintenance!

Wooden GazeboWooden structures that are usually floored, with solid roofs and support pillars, and have a porch-like appearance. They often have short fenced in sides, which can be used for growing plants upon, although sometimes are left completely open. Wooden gazebos can be freestanding over patios or attached to garden walls, and are generally installed in areas where a full 360 degree view is desired. Because they are made of wood, which requires regular maintenance to keep it looking nice, O’Neill’s Green Services recommends installing an aluminum pergola or patio cover to enhance your outdoor living space.

Arbors are small framed structures that are often arched, and commonly made of wood. They are usually decorated with a variety of climbing plants and placed over a path or gate to be used as a passageway.

Wire trellis with red flowers


Wood or designed wire frames that are used to support vines and plants. They are most often placed along blank walls to add decor, but can also be used to add height to a fence, or to add privacy to outdoor areas.



Aluminum Patio Covers

These attached structures provide shade and/or rain protection for a patio or deck, creating an enjoyable outdoor space that can be used for anything from the basic family BBQ to an elegantly decorated entertainment area. Most homeowners choose a solid roof for their patio canopy to allow for year round use, although lattice roofs are also an option. Undecided on which option would best fit your home and family lifestyle? O’Neill’s Green Services can help! Our experienced professional installers can give you the best of both worlds by giving you a combination of the two.

Why Choose Aluminum Over Wood?

When it comes to building patio covers and pergolas, there are many reasons why O’Neill’s Green Services recommends installing aluminum products, rather than wood. Besides requiring little to no maintenance, their appearance stays looking like new longer. Aluminum does not fade, warp or crack due to weather conditions, the way that wood does. This means that it never needs to be sealed or painted, saving customers the high costs of materials and labor. They never rust, and can be cleaned easily with water and a cloth or sponge. Unlike wood, aluminum patio covers and pergolas will never be damaged by termites, resulting in longer enjoyment. They are designed to have the appearance and feel of real wood, while providing the durability to withstand all types of weather.
