What changes the quote?
Wall height and length, access, excavation, soil and slope, spoil removal, drainage, sleeper finish, and any engineering or permit requirements.
Guide prices do not replace a site quotation. The wall design, posts, footings, drainage and any approvals must match the actual site conditions.
Uneven yards and larger outdoor projects
Plan retaining levels before finalising the deck.
Where a retaining wall changes the usable ground level, its position, height and drainage can affect the deck frame, finished surface, steps and connection to the rest of the yard. Assessing both areas together helps define a practical sequence without treating every sloped property as the same job.
The site assessment considers where water can move, how air can circulate below the deck, the distance between the wall and deck, access for excavation and materials, and transitions to doors, paths, fencing, gates, turf and garden beds.
Send yard measurements and photosHow a combined retaining-wall and decking quote is planned
1. Record the existing levels
Show the high and low sides of the yard, door thresholds, boundaries, pits and the approximate wall and deck locations.
2. Confirm drainage and access
Identify where water currently travels and how soil, sleepers, posts, framing and waste can move through the property.
3. Choose the visible materials
Confirm timber or concrete sleepers for the wall and Merbau or composite boards for the deck. The construction underneath is assessed for the actual site.
4. Coordinate adjoining work
Include planned fencing, gates, concrete, turf or garden beds so finished heights and edges can be considered before the quotation is finalised.
For board comparisons and current decking guide rates, see Merbau and composite decking in Melbourne. For wall drainage and site-assessment guidance, see the Melbourne retaining-wall service page.
Choosing timber or concrete sleepers
Timber can suit customers who prefer a natural garden finish. Concrete sleepers are a practical choice when durability and a consistent finish are priorities. The right option depends on the wall height, surrounding structures, drainage and the look you want to achieve.
Retaining work can also be coordinated with fencing and gates, landscaping or decking and other quoted outdoor work.

Frequently asked questions
How much does a retaining wall cost?
Current timber sleeper wall guide rates are $255/m + GST for 400mm, $270/m + GST for 600mm, $350/m + GST for 800mm and $425/m + GST for 1m. Plain concrete sleeper walls are $290/m + GST for 400mm, $330/m + GST for 600mm, $450/m + GST for 800mm and $550/m + GST for 1m.
Can a retaining wall and deck be planned as one project?
Yes. Evergreen Exteriors Care can assess the retaining wall, drainage, deck area, levels and access together when both services are included in the requested scope. Each item is measured and confirmed in the written quotation.
Should the retaining wall or deck be built first?
The sequence depends on the site. Where a retaining wall controls ground levels or drainage, its layout normally needs to be resolved before the deck frame and finished height are confirmed.
What affects the final retaining-wall and decking quotation?
The quotation can be affected by wall length and height, sleeper material, deck size and board choice, access, excavation, ground levels, spoil removal, drainage, frame and support requirements, stairs, and any engineering or permit requirements.
What should I send for a combined quote?
Send the property suburb, approximate retaining-wall length and height, approximate deck length and width, the intended deck height, clear photos of the yard and access, and your preferred wall and decking materials.
See the backyard planning guide for the recommended order of retaining walls, fencing, concrete, decking and turf.
