Sarkis successfully repaired my leaning pier under the house. His expertise was evident throughout the job. He finished the job in record time. To my amazement! He is brilliant!!! I had been worrying about the pier for some time b4 I called him. Don’t bother calling anyone else! Satisfied customer 100 per cent.

Sarkis from Substructure Solutions recently completed a sizeable repair job for me. He was professional and easy to work with starting from the initial assessment and quoting, through to completion of the job. It was completed on time and on budget, and he was always quick to address my many questions and concerns along the way. I should also mention that he went above and beyond when he helped to secure a shed that threatened to blow away in a mini-gale – quite unrelated to the contracted job. I am very happy to recommend Sarkis and his team.

Top bloke, transparent with the pricing. Came early, did the job (added three support stumps) and finished early. Easy to work with. Definitely would work with again in the future.

Why Invest in a Basement Construction?

A basement extension offers way beyond just extra space. Getting one enhances your home’s value, functionality, and energy efficiency. Our basement construction process provides a durable, long-lasting structure that meets your specific needs.

With a foundation excavation, you can maximise your space by extending your home’s underground footprint without altering its footprint. This naturally insulates, which makes you comfortable no matter the weather. 

A well-designed basement extension under the garden adds significant market appeal. Convert your basement into a personal hideaway, guest suite, wine cellar, gym and more. Reimagine your property’s possibilities.
