Underpinning
Sydney
Affordable house underpinning and foundation repairs across Greater Sydney
Strong, stable foundations keep your home safe and your biggest asset protected.
When cracks spread through walls, doors stop closing properly and floors feel uneven, you need an underpinning specialist who knows Sydney soils and moves fast on quotes and repairs.
At Underpinning Sydney, the focus stays on structural stability, clear communication and tidy work from first site visit to final clean up.
You get a straight explanation of what is going on under your home and a plan to fix it in the most practical way.
Underpinning Services Sydney
Targeted underpinning for brick and block houses with sinking or moving foundations.
We work with engineers where required, dig in staged sections, and pour new footings to re support your home and reduce further movement.
Re levelling for concrete slabs, garage floors and extensions that have dropped or tilted.
Resin or concrete based solutions depend on soil conditions, access and the extent of movement.
Structural repairs for cracked brickwork, lintels and masonry where movement has already occurred.
The goal is to stabilise the structure first, then repair visible damage in a way that lasts.
Underpinning and strengthening for retaining walls and subfloor piers that show signs of failure.
Important on sloping sites where movement affects both your home and neighbouring properties.

Why Choose Underpinning Sydney
Underpinning specialists only
The focus is on underpinning and related structural remedial work, not general handyman jobs.
That keeps the process tight and efficient.
Sydney soil experience
Many Sydney homes sit on reactive clays and fill that move with dry and wet seasons.
Working with these conditions every day helps the crew spot causes quickly and design the right repair approach.
Clear, upfront pricing
You receive a written scope that explains what work is needed, how long it is likely to take, and what it should cost before work starts.
No vague jargon and no surprise line items at the end.
Minimal disruption to your life
Work areas stay contained, access is planned with you, and the team cleans up as they go.
The aim is to keep your home as liveable as possible during structural work.
Local and responsive
Underpinning Sydney serves the whole metro area, from the North Shore and Inner West through to Western Sydney and the Sutherland Shire.
You deal with someone who understands local councils, local builders and local conditions.

Underpinning Sydney Reviews

Sara L.
Cracks had spread across three rooms and one sliding door stopped working. Underpinning Sydney walked me through the options, handled the engineer and finished on time. The house feels solid again and they left everything tidy.
— Inner West
David R.
I worried the whole back of the house would need rebuilding. The team inspected, explained the movement and underpinned only the sections that needed it. The result looks great and the doors now close properly.

Our Process
Step 1 – Site inspection and assessment
We visit your property, check cracks, doors, windows, subfloor and drainage, and listen to your concerns.
Where needed, we recommend an engineer to confirm the structural design.
Step 2 – Proposal and fixed scope
You receive a written proposal outlining the underpinning method, access points, expected depth, timing and a clear price guide.
We answer your questions before any commitment.
Step 3 – Underpinning and clean up
The crew completes digging, underpinning and concrete pours in stages to keep your home supported.
Once works are finished, we backfill, tidy the site and walk you through what was done.
Frequently asked questions
Here, we’ve answered some of the most common questions about our fast, affordable, and all-inclusive underpinning process.
What are the common signs that a house in Sydney needs underpinning?
Typical signs include stepped cracks in brickwork, gaps around window and door frames, doors or windows that stick, and floors that slope or bounce.
If you see more than one of these in the same area, it is time to book an inspection.
How much does underpinning a house in Sydney cost?
Pricing depends on how many underpinning pins are required, how deep they need to go and how easy it is to access the work zones.
Some small jobs sit in the low tens of thousands, while larger projects cost more.
The only way to know is to have the site assessed and a tailored quote prepared.
How long does underpinning take?
Most residential underpinning projects are staged over several days to several weeks, depending on house size, soil depth and weather.
During the quote process, we outline the expected time frame so you know what to expect.
Do I need to move out while underpinning is done
For many houses, owners stay in place while work happens, with some areas of the home blocked off during the day.
In more complex cases, or where access is tight, a short temporary move might be more comfortable.
We talk this through with you before work starts.
Will underpinning stop all future movement?
Underpinning aims to stabilise the foundation in the affected areas and reduce further movement.
Soil conditions, drainage and future works on or near your property still play a role.
We discuss drainage or other preventative steps if they are relevant for your site.
