Pipes don’t last forever—and when they start showing signs of wear, it’s important to act before a minor issue becomes a major mess. At Curran, we’ve been helping homeowners across Wollongong, the Illawarra, Shoalhaven, and the Sutherland Shire replace everything from aging copper and clay pipes to stormwater and sewer lines. If you’re seeing discoloured water, hearing strange gurgles, or noticing repeated blockages, it could be a sign your pipes are deteriorating or collapsing.
Sometimes repairs aren’t enough. If your pipes are corroded, sagging, or riddled with cracks from ground movement or tree roots, a full or partial replacement may be the safest and most reliable option. We’ll inspect your system with CCTV technology, explain what’s happening underground, and help you make a smart call based on the actual condition of your pipes—not guesswork.
Over time, even the strongest pipes can fail. Ground movement, shifting soil, and expanding tree roots all place stress on underground plumbing. Add in the natural corrosion of metal pipes or the fragility of old clay lines, and you’ve got a recipe for damage that builds up slowly until it turns into an emergency. Many older homes in our region still rely on outdated piping materials that simply weren’t built to last.
At Curran, we see it all: cracked pipes from heavy rainfall and erosion, backfall issues from poor installation, or long-term blockages that weaken the pipe walls. If you’ve got foul smells, water pooling, or your drains keep backing up, it’s worth investigating whether the issue is more than surface-level. Our goal is to identify the true cause—not just patch the symptoms—and give you a lasting fix.
Whether you need to replace a single section or an entire plumbing line, Curran has a solution that fits. We offer both traditional excavation and modern trenchless pipe replacement methods, depending on your property’s layout, the pipe material, and the severity of damage. From stormwater pipes that overflow during heavy rains to sewer lines invaded by roots, we’ve got the tools and know-how to get it sorted.
We replace a range of pipe types including clay, cast iron, copper, and older PVC. Our team can advise on the best new materials for your situation—typically high-performance PVC or PEX piping that’s resistant to corrosion and root intrusion. And if your pipes are beyond relining, we’ll walk you through your options with no pressure, just honest advice and fixed pricing.
We start with a thorough assessment using high-resolution drain cameras to pinpoint the issue. If a replacement is necessary, we’ll outline exactly what needs to happen, from digging access points to installing new, long-life pipes that meet Australian standards. Depending on the job, we may use pipe bursting (where a new pipe is pulled through the old one) or traditional trenching, especially if access is limited.
We understand that replacing pipes sounds disruptive—but our experienced team makes the process smooth and efficient. We’ll protect your property, limit any mess, and keep you informed at every step. And if we can use trenchless techniques to avoid tearing up driveways, paving, or gardens, we absolutely will. It’s all part of how we deliver stress-free plumbing backed by decades of local trust.
Pipe replacement costs can vary depending on length, depth, pipe material, and how accessible the damaged section is. But one thing doesn’t vary at Curran—our commitment to transparency. We provide upfront quotes with clear pricing and no hidden extras, so you know what to expect before we begin.
If cost is a concern, talk to us about our 0% interest payment plans. We know pipe issues often come out of the blue, and we’re here to help you handle them without financial stress. Whether it’s a small replacement job or a full sewer line renewal, we’ll work with your budget and timeline to find a solution that gets the job done right.
With the right materials and proper installation, new plumbing pipes can last 50+ years. At Curran, we use only high-quality, water industry-approved products designed for Australian soil conditions and tough use. Once your new pipes are in, you can relax knowing they’re built to withstand tree root intrusion, shifting ground, and daily wear and tear.
To keep things flowing smoothly, we recommend regular drain maintenance, especially if your property is prone to blockages. Avoid flushing wipes, don’t pour grease down the sink, and keep large trees away from underground pipes. We also offer professional drain cleaning and inspection services to help catch early warning signs and extend the life of your new system.
Old or broken pipes don’t just cause inconvenience—they can impact your home’s safety and your family’s health. Leaking sewer lines can create mould, attract pests, and release harmful gases like methane. Meanwhile, stormwater pipes that fail can cause yard flooding or damage your foundations. That’s why it’s so important to act early when you notice signs of trouble.
At Curran, we prioritise not just fixing your pipes, but protecting your property for the long haul. Our expert team works cleanly, safely, and always complies with local codes and environmental regulations. Whether we’re digging or using trenchless tech, we treat your home with the same care we’d give our own—and we back our work with clear warranties and ongoing support.
