Trex Decking Specialists

At Green Side Up, we specialize in installing Trex composite decking in Toronto and York Region. Our contractors know how to maximize your home’s value, starting with quality wood-alternative materials.


Our Deck Construction Process

1. Discovery Call

Before choosing your deck boards and colours, you’ll receive a free discovery call with our founder, Jay Saveall. This is your opportunity to learn more about our custom services, costs, timelines and materials, and ask any burning questions.

2. Deck Design

The next step is an on-site consultation with our architectural team. During your consultation, they’ll measure your yard, create a deck design, and prepare the technical drawings required for your permit. Whether you have a cedar or trex deck design, we work with you to make your dream deck a reality.

3. Materials

Choosing the right material for your new deck will set the tone for your upkeep and maintenance year over year. Your deck designer will go over your wood and composite deck options and help you determine which material is best suited to your space.

4. Custom Deck Installation

Once you settle on your deck design and materials, it’s time for us to get to work. We will provide custom deck installation services efficiently and to your specifications. 

We believe in using the best construction practices at Green Side Up Contracting. We use Helical Piles: seven-foot galvanized screws that are installed by the machine, and set to a torque level that will never fail. Long gone are the days of concrete footers!

Our Decking Materials

Trex Decking

Trex decking is an engineered deck material that’s designed to last. This sustainable solution can help you get the most out of your deck without staining, scratching or fading.

Cedar Decking

When it comes to building a deck, the right wood makes all the difference. Cedar decking is a durable material preserved naturally to prevent rot, decay, or insect damage.

Pressure-Treated Decking

Pressure treatments are designed to extend and preserve the life of wood. Our pressure-treated decks are moisture-resistant, low-maintenance, affordable, and long-lasting.
