Deck Builder FAQ — Whitby
How much does a custom deck cost in Whitby?
Most Whitby decks fall between $45–$90 per square foot for pressure-treated builds and $85–$160 per square foot for composite decking including framing, footings, railings, and finishing. We provide a fixed written quote after a free on-site consultation.
How long does deck construction take in Whitby?
A typical Whitby single-level deck takes 5–10 working days once permits are approved. Larger multi-level or composite builds run 2–3 weeks. Weather can shift timelines slightly, but we always give a realistic schedule up front.
Do I need a permit to build a deck in Whitby?
Usually yes — decks attached to the house or over 24 inches off grade require a municipal building permit in Whitby. We prepare drawings and submit the permit application as part of your project.
What's the best deck material for Whitby winters?
Capped composite (Trex, TimberTech, Fiberon) and western red cedar both perform excellently through Ontario winters. Composite offers 25+ year warranties with no staining; cedar delivers classic wood aesthetics and natural rot resistance.
