- Size and Shape: Larger decks naturally cost more due to increased material and labour requirements. Complex shapes or multi-level designs will also increase the price.

- Foundation and Support: The complexity of the foundation, especially for elevated decks or those on sloped terrain, will add to the overall cost. This includes the number and depth of footings required.
- Additional Features: Incorporating features like built-in seating, custom railings, integrated lighting, privacy screens, or pergolas will increase the project's budget.
- Seasonal Demand in Spring 2026: As mentioned, Spring 2026 is a peak season for outdoor projects in Ajax. The surge in demand means contractors are in high demand, which can lead to slightly higher pricing compared to the off-season. Booking early is key to managing costs and availability.
