The building of a deck is one of the best home improvement projects that can add value to your property while providing a comfortable and enjoyable outdoor living space for relaxation and entertainment. However, building a deck is not an easy task and requires careful planning, design and execution to ensure that your deck is safe, durable and aesthetically pleasing. We understand the importance of building a deck that fits your needs and budget while exceeding your expectations. That’s why we take a detailed approach to pricing, considering all aspects of the design, including the size of your deck, shape, height, decking type, and overall appearance. This ensures transparency in building the cost of the deck every step of the way. To make sure your deck stands the test of time, we use only the best materials for the job. Our decking cost process includes a number of steps that take into account every detail of your project, from the foundation to the railing. Let’s take a look at each aspect of our decking cost estimating process.


The foundation is the most critical aspect of any deck, and choosing the right foundation is important to ensure that your deck is stable, safe and durable. We use two types of deck foundations: concrete or helical piers.

Concrete is the classic and most commonly selected foundation. When it is done right, it can be an excellent choice in many cases. Concrete foundations are among the least expensive and have been used for decades as deck foundations.

Helical pile systems are more expensive than concrete foundations, but look less bulky. They have a greater load capacity, allowing the number of columns to be reduced. Helical is a permanent foundation solution that lasts a lifetime. These foundations are used in the construction industry to provide support for everything from tiny lighthouses to massive engineering projects.

Choosing the right type of foundation is critical to the longevity of your deck, and our experts can help you make the right choice based on your needs and budget.

The structural frame of your deck is the backbone of your entire deck. It holds everything in place and supports the weight of the deck. There are two main types of structural frames: wood and metal.

Wood is the most common material for a deck’s structural frame, and for good reason. It’s reliable, affordable and has a long history of use. The wood frame has a long history and has established itself as a reliable and affordable material.

Metal framing is the next evolution in deck framing. It’s weather-resistant, fire-resistant and moisture-resistant. The metal frame is very durable and can last up to 60 years. Our deck experts can help you choose the best material for your deck structure frame based on your preferences and budget.

The right deck flooring is essential to the overall look and feel of your deck. There are many deck flooring options to choose from, each with different lifespans and installation systems that work for different styles and types of applications. Our deck experts can help you make the right choice for your preferences and budget. Pressure-treated decking is the more affordable choice. It’s resistant to insect attack and rot, so it lasts a lot longer than untreated wood. Cedar is a durable wood that is innately resistant to decay, insect attack and moisture absorption. It’s an excellent choice for people who prefer to avoid chemical treatments. Composite decking is virtually low-maintenance and is made of wood fiber and plastic film. PVC or vinyl decking is made entirely of synthetic materials and has the highest rating for durability. Exotic wood decking, such as IPE, offers a natural, stunningly luxurious look, extreme durability and longevity. Our decking experts will help you choose the best decking option for your preferences and budget. They will also explain the benefits and drawbacks of each type of flooring so you can make an informed decision.

Railings can come in different types and materials such as wood, iron or aluminum, glass, composite or PVC railings. Our experts will help you choose the railing that meets your needs while being easy to maintain and clean. We want to make sure that your deck is not only beautiful, but also safe and sustainable.

Our deck building cost process involves a series of steps that take into account every detail of your project. We work with you to select the best deck foundation, structural frame, decking and railing options for your preferences and budget. We understand that every project is unique, and we will make sure that your deck reflects your style and personality. Every part of the deck can be made of different materials and different qualities of those materials. In each case, it is an individual customer’s choice based on budget, design, personal preference, or driven by the city’s building code.

As you have learned, calculating the cost of a deck requires a project inspection or asking the homeowner for details (if they can provide them) to understand the types of materials to be used and the construction time. Because of this, estimating a project without a professional inspection or based on average prices will not be accurate. And the difference can be thousands of dollars. Rest assured that Demex Decks will provide you with the best recommendations for materials and design. You can also view initial deck prices or request a quote for your project.

To sum up, building a Deck is a significant investment, but one worth making. It’s a project that can add value to your property, enhance the quality of outdoor spaces, and provide a place for you and your family to relax and unwind. At our Toronto-based company, we are committed to providing quality projects and expert deck building. Contact us today to find out how we can help you build the deck of your dreams.
