Frequently Asked Questions

How much does leak detection cost in Sydney?

Leak detection costs can vary depending on the type and location of the leak. At In House Plumbing, we provide transparent, upfront quotes so you’ll know exactly what to expect before we begin. Our pricing is designed to be fair, competitive, and reflective of the high-quality service we deliver.
The real value comes in preventing further damage — early detection saves thousands in potential repairs. By choosing our professional service, you get both cost-effective pricing and long-term protection for your property.

Do I need to dig up my yard or walls to find a leak?

Not usually. With today’s advanced technology, most leaks can be detected without invasive digging or tearing down walls. Our team uses thermal imaging cameras and acoustic leak detection to locate leaks quickly and accurately.
In some rare cases where leaks are buried deep or in hard-to-access areas, small access points may be needed. Even then, our approach focuses on minimising disruption while ensuring the problem is solved completely.

What are the signs of a hidden water leak?

Common signs include unexplained increases in your water bill, damp patches on walls or ceilings, mould growth, musty smells, or reduced water pressure. You may also hear running water when taps are turned off.
If you notice any of these symptoms, it’s best to call a professional plumber quickly. Early leak detection prevents serious property damage and helps keep repair costs under control.

Is leak detection covered by insurance?

Many insurance policies cover water damage caused by leaks but may require professional leak detection and reporting for claims. That’s why we provide insurance-approved reports to make the process smoother for homeowners and business clients.
It’s important to check your policy details, as coverage can differ. Our friendly team is happy to guide you on what information insurers typically require and ensure you have the right documentation.

How quickly can you respond to a leak?

We understand leaks are stressful and often urgent. That’s why our plumbers are available 24/7 for emergency leak detection across northwest Sydney. When you call, we prioritise fast response times so we can get to your property quickly and prevent further damage.
