⭐⭐⭐⭐⭐


Five stars for Sam and his team (Lewis and Justin). They turned up each and every day exactly when they said they would and kept me well informed about the work and the process.

They worked hard in wet, difficult conditions and left the property and the job clean and tidy.

Most importantly for me they were personable and genuinely nice people to work with who didn't treat me like an idiot just because I am a woman and showed and explained their work to me as it progressed.

Highly recommended

Why homeowners call us

Underpinning is for homes with failed strip footings supporting brick walls, not stumps or slabs. Where restumping replaces failed timber or steel stumps, underpinning repairs a strip footing that's cracking or sinking. We dig new support pins deep beneath the existing footing, concrete them in, then lift the house and lower it onto the new pins for a stable, level foundation.

Frequently Asked Questions

How do I know if I need underpinning or restumping?

If your home has brick walls on strip footings rather than being raised on stumps, underpinning is the right fix. Not sure? We're happy to inspect your property and let you know.

Can I stay living in the house while the work is done?

Yes.

How much does underpinning cost?

It depends on the size of your slab and the extent of movement, so every job gets a free on-site inspection first. Give Sam a call on 0423 461 053 for an estimate.
