Piers are a critical part of your home's foundation, supporting the structure and helping prevent movement over time. Factors such as moisture, salt exposure, poor construction, and shifting soil can all contribute to pier deterioration, leading to costly structural issues if left untreated.

At Billcorp, we provide expert pier repair and replacement services tailored to your home's specific needs. With over 30 years of experience, our team identifies the root cause of foundation movement and delivers reliable, long-term solutions to restore stability and protect your property's value.

Throwback to this lintel replacement project in Woonona 🧱

The lintel above the front window had rusted and failed, compromising the structural integrity of the brickwork. Our team came in, propped the existing brickwork, removed the deteriorated lintel, and installed a new galvanised steel lintel at approximately 2,500mm wide.

Once secured with non-shrink grout, we matched the mortar to the existing brickwork and finished with an acid wash for a clean, professional result. You'd barely know we were there, except the house is now structurally sound and looking great!

It's not always the most obvious repairs that matter the most, but get them wrong and they cause serious problems down the line. This is exactly the kind of work we love doing.

If you've noticed cracking or movement around your windows or door frames, it might be worth getting it looked at. We service Sydney, Wollongong, and Newcastle, and we're always happy to have a chat. 📲

Job done in Thirroul! 🔧

We’ve just wrapped up a pier replacement project in Thirroul and couldn’t be happier with how it turned out. What was an unstable, ageing foundation is now solid, safe, and built to last well into the future.

This is exactly why we do what we do, giving homeowners the confidence that their property is in good hands. No cutting corners, no rushing the job. Just quality work, done properly.

A big thanks to our client for trusting us with their home. If you’re in the Wollongong area and have been putting off a foundation issue, now’s the time to act. We’d love to help. 💪

We’re particular about the products we use and there’s a reason we choose Unipier. 🏗️

When it comes to pier systems, not all products are created equal. We’ve tried plenty over the years, and Unipier consistently comes out on top. It’s engineered specifically for Australian conditions, it installs with minimal disruption to your property, and most importantly it lasts.

A lot of cheaper alternatives look fine on paper but don’t hold up when the soil moves or moisture gets in. We won’t put our name on work we don’t believe in, so we only use products we trust completely.

Your home deserves the best foundation and so does the repair.
