Excavation in St Helens Park
Excavation done properly
Excavation in St Helens Park ranges from detailed digging next to an existing house to opening up a rear yard for a new slab. In both cases the levels, set out and service locations are confirmed before work starts.
Before any digging in St Helens Park, underground services are located through Before You Dig Australia, and where needed by a service locator. This protects the services and keeps the job on program.

Local considerations
Planning excavation in St Helens Park
What we check first
Flood and bushfire mapping can set minimum floor levels or material requirements, so we check the planning certificate first.
Homes in the area
Homes across Macarthur include newer estates and established family homes on larger blocks, plus semi-rural acreage. We look at the existing structure, site access and levels in St Helens Park before pricing, so the quote reflects the actual house.
Council approval
Excavation is usually approved as part of the building work it supports. Deep cuts near boundaries can need engineering, shoring and notice to neighbours. We confirm the approval pathway for your St Helens Park property during the site visit.
Questions
Excavation in St Helens Park, answered
Can you build the slab or footings as well?
Yes. We carry out concreting and carpentry, so excavation, footings, slabs and framing can be delivered by one team.
What happens if you hit rock?
Rock and poor ground cannot always be seen before digging. Our quotes state how rock is allowed for, so any extra cost is clear before work continues.
