There are many reasons why you might need to replace your brick piers. If the piers are cracking or crumbling, they may no longer be able to support the weight of your home.

If you suspect that you may need to replace your brick piers, contact us and we will assess the condition of your piers and recommend the best course of action.

Concrete Crack Repairs

Concrete Crack Repairs

Concrete cracks are inevitable and can happen for a variety of reasons. Whether it’s due to settling, tree roots, freezing temperatures, or simply wear and tear, cracks in your concrete can create serious problems if left unaddressed. Not only can they be unsightly, but they can also lead to water infiltration, which can cause further damage to your foundation, walls or slab. Call for a quote.

Jammed Door Repair

Jammed Door Repairs

If your door becomes stuck or jammed, it can be a sign of underlying issues with your structure. Not being able to open or close your doors or windows can make it difficult to get in or out of your home and can pose a serious security risk. In most cases, jammed doors can be a sign of more serious issues with your foundation, especially if your building is old or your building is built on unstable ground.

Client Testimonials

Mark came out on time to provide a quote for a floor levelling and brick pier replacement work. He took his time to explain how the situation may have occurred and options to remedy. Certainly seems to know his stuff. Was able to talk about the modifications that were done to the house from what he was seeing in the foundations. We haven’t proceeded with the works yet, but I know where I’d be heading.

Manish Gupta

Mark and his team have done two projects at my house. They fixed the sinking floor and helped to fix a disaster project by another tradie. These guys are fantastic! Their quote is reasonable, always comes on time, does a great job and keeps the place clean after themselves. Very professional and experienced, give honest advice and suggest the best approach. I am very happy with the results and will gladly work with them again.

Evgeny Novikov

Thanks to Mark & his team for an extremely professional job!!
We were really impressed (as were our neighbours) at the level of care taken especially with regard to access, the tricky nature of the site and for the clean up afterwards. They definitely live up to their name and we would have no hesitation in recommending A1 Underpinning.

Underpinning & Foundation Repairs FAQs

We’ve taken the liberty to answer some of the most common yet critical questions pertaining to Sydney underpinning, foundation repairs and structrucal restorations.

1. What is underpinning?

Underpinning is the process of strengthening and stabilising the foundation of an existing home building or commercial structure. This is done by excavating around the perimeter of the foundation, and then installing support beams or posts to reinforce the original foundation.

2. Why would I need underpinning?

There are several reasons why you might need underpinning. Perhaps the foundation of your home is settling, or cracking due to age or wear and tear. Or, you might be planning an extension to your home, which would require additional support for the new structure.

3. How much does underpinning cost?

The cost of underpinning depends on a number of factors, including the size and condition of your existing foundation, the type of underpinning you need, and the difficulty of access to your property. Generally speaking, underpinning can cost from $5,000 up.

4. How long does underpinning take?

Again, this depends on a number of factors, including the size and condition of your existing foundation, the type of underpinning you need, and the difficulty of access to your property. Generally speaking, underpinning can take anywhere from a few days to a few weeks to complete.

5. Will I need planning permission for underpinning?

You might need planning permission for underpinning, depending on the type of work you are planning to carry out. It is always best to check with your local council before starting any work on your property. At A1 Underpinning, we can help you on this aspect. Contact us today if you need our help.

6. Do I need a building permit for underpinning?

You will need a building permit for underpinning if the work you are planning to carry out is classed as ‘building work’. This includes excavation work, and the installation of support beams or posts. Building permits are generally issued by your local council.

At A1 Underpinning, we will work closely with you from start to finish. Contact us today if you need help.

7. Are there any risks associated with underpinning?

Underpinning is a complex process, and there are always risks associated with any building work. However, these risks can be minimised by choosing a reputable and experienced contractor like A1 Underpinning. We’re licensed and insured to carry out all facets of underpinning, foundation repairs, structural restorations, drainage repairs and all sorts of house relevelling. Contact us today if you need our help.

There are many benefits to underpinning, which include:

1. Improving the stability of a building: This is the most obvious benefit of underpinning, and is the reason why many people choose to undertake this process. Underpinning can help to stabilise a building that has been damaged by subsidence, or that is at risk of collapsing. Staying in a secure home gives you peace of mind, and this is always what we aim for our Sydney clients.

2. Extending the life of a building: By improving the stability of a building, underpinning can help extend its life. This is particularly beneficial for historic buildings, which may be at risk of collapsing if foundations are not repaired or supported.

3. Preventing further damage: Underpinning can help prevent further damage to a building, by stabilising it and preventing it from moving. This can help prevent cracks from appearing in walls or floors, and can also stop doors and windows from misaligning.

4. Improving the appearance of a building: Underpinning can help improve any home or structure’s appearance. This is because underpins level out a building that has been damaged by subsidence. Underpins also straighten walls that have become crooked.

5. Increasing the value of a building: It increases the value of a building, because underpinning makes a structure more stable, durable and safe for use.

If you want to enjoy the benefits of underpinned home, contact A1 Underpinning today.
