Reviews

What Adelaide Hills homeowners say.

★★★★★
“Three quotes, and Tierline was the only one that gave us a real by-the-face-metre price before they even came out, and the only one that put the drainage on the quote as its own line. The concrete-sleeper wall is dead straight along a sloping block, raked to follow the fall, and the number on the day matched the estimate.”

★★★★★
“Our old wall was bulging and over a metre, so it needed doing properly. Marco brought the engineer, sorted the council development approval and itemised exactly what the over-a-metre line cost instead of folding it into a round number. Signed off, certified, and no chasing the council ourselves.”

Local questions

Retaining walls in Balhannah, answered.

Do you charge extra to come to Balhannah?
No. Balhannah is within 35km of our Stirling base, so there is no travel surcharge. The free site assessment and the by-the-face-metre quote are the same whether you are around the corner or at the edge of the radius.
How soon can you build my wall in Balhannah?
We aim to be on site for a free assessment within 48 hours and to have the written quote back to you within two business days of measuring the fall. The dig itself depends on the wall, the material lead time, and whether the height needs an engineer’s design and council approval first. A straightforward garden wall under a metre is often a two to four day job once we start, while a tall engineered wall takes longer, and weather can move concrete days.
Is access a problem for a retaining wall on a steep Balhannah block?
It can be, and it is exactly what we check on the assessment. A steep or tight block can mean the excavator and the materials are harder to get in, which adds excavation and machine-access cost, and the fall changes how the footing and the wall are set out. We confirm the access on site and put any access line on the quote, never sprung on you at the end. We build on the sloped blocks the Hills are full of every week.
Who pays for a boundary retaining wall in Balhannah?
A retaining wall is not a 50/50 shared boundary divider. As a general rule in South Australia, the wall is the responsibility of the owner whose land it holds up, that is, whoever cut or filled the ground, and the cost follows who benefits, under the Planning, Development and Infrastructure Act. We give you a clear, itemised quote you can put in front of the neighbour, plus a plain-English note on how the responsibility usually falls, so the conversation next door is the easy part. This is general guidance, not legal advice.
