FAQ’S | Decking Newcastle
Do you build both timber & composite decks?
Yes. We construct both hardwood / treated pine timber decks and low-maintenance composite decking. We’ll walk you through the pros and cons of each option during your site meeting to help you choose what best suits your space and budget.
Is composite decking low maintenance?
Yes. Composite decking requires far less maintenance than traditional timber. It doesn’t need regular staining or oiling and is designed to resist fading, moisture and insect damage.
How long does it take to build a deck?
Most standard residential decks take between 1–3 weeks depending on size, height and access. Larger or elevated decks may require additional time for structural preparation.
Where is your service area?
We build decks across Newcastle, Lake Macquarie, Port Stephens & Maitland
Can you replace or upgrade an existing deck?
Absolutely. We can assess your current deck and advise whether repairs, structural upgrades or a full replacement is the best solution.
How do I get started?
Simply fill in our website form to request a quote or book a site meeting. We’ll inspect the area, discuss design options, and provide a clear, transparent quote before construction begins.
