Who is Retaining Walls Sydney?
Retaining Walls Sydney is a referral service, not a construction company. Enquiries made through this site are routed to independent, third-party retaining wall contractors working across Sydney — the contractor quotes the job, builds the wall, and is responsible for the work. That distinction is stated plainly here because it matters: you should always know who you're actually hiring. Ask the contractor to see licence and insurance certificates before work starts.
What the service stands behind is the process around the build: fixed written quotes before any work begins, honest advice on council and engineering requirements — the contractor can advise, but council decides, and nobody should promise approval — and drainage treated as part of the wall rather than an optional extra bolted on at the end.
How does the quote and referral process work?
Three steps. First, describe the job — wall type, rough length and height, and where the block is — by phone on 02 5137 7616 or through the contact page. Second, the enquiry is passed to an independent contractor working in your part of Sydney, who inspects the site and provides a fixed written quote. Third, you decide: there's no obligation, and the cost guide gives you dated 2026 price bands to sanity-check any quote against.
If the wall is tall enough to need an engineer or certifier — generally past the 600mm mark under NSW planning rules — the contractor can walk you through the likely approval path before you commit. The engineered walls page explains those thresholds in detail.
