Home » Slab Leak Detection in Sydney
For over 20 years, homeowners and businesses across Sydney have trusted us to find and fix hidden leaks with precision and care.
Are you noticing unusually high water bills or mysterious damp spots on your floors? A slab leak could be silently damaging your property from below. At In House Plumbing, we specialize in fast, non-invasive slab leak detection in Sydney—helping you uncover the source of the problem before it becomes a costly repair. Our experienced local plumbers use advanced tools to detect leaks under concrete without tearing up your floors, giving you peace of mind and protecting your home or business from further damage.
At In House Plumbing, we’re more than just a service—we’re part of the community. With over two decades of hands-on plumbing experience, we’ve built a strong reputation for delivering honest, efficient, and top-quality solutions. Our team is known across Sydney for showing up on time, getting the job done right the first time, and treating your property with the respect it deserves. Whether you’re in Blacktown, Castle Hill, Rouse Hill, or any of the surrounding suburbs, you can rely on us for slab leak detection you can trust.
We’re proud of our 5-star customer reviews and transparent pricing model, with no hidden fees or unexpected charges. When you call us, you’re getting more than a plumber—you’re getting a professional partner who genuinely cares.
Slab leaks can go undetected for weeks—sometimes even months—causing serious damage to your foundation and interior floors. Our team uses state-of-the-art technology, including thermal imaging and acoustic sensors, to detect the exact location of the leak without breaking through your concrete slab.
This service is ideal for residential and commercial properties showing signs of water leaks beneath the surface. If you’ve noticed damp floors, decreased water pressure, cracked tiles, or mold growth, don’t wait—early detection can save you thousands in repair costs. We make the process fast, clean, and accurate, helping you resolve the issue with minimal disruption.
Worried about messy or destructive leak investigations? Don’t be. Our non-invasive slab leak detection methods mean we can find the problem quickly—without tearing up your floors or guessing where to dig. We use pinpoint technology that ensures minimal impact and maximum accuracy.
Our tools allow us to identify even the smallest water leak under your slab before it spreads. This saves you from costly excavation, preserves your flooring, and speeds up the repair process significantly.
We’ve proudly served Sydney residents for more than two decades, and our results speak for themselves. Hundreds of local homeowners and business owners have relied on In House Plumbing to detect and resolve hidden leaks with professionalism and care.
We’re a family-run business built on integrity, transparency, and workmanship that lasts. When you choose us, you’re choosing a team that values long-term relationships, clear communication, and outstanding service from start to finish.
Time matters when there’s a slab leak. Left unchecked, it can cause serious foundation issues, lead to mold growth, or result in expensive water damage. That’s why we offer fast, responsive service across Sydney—including areas like Glenwood, North Kellyville, Cherrybrook, and Kings Langley.
Whether it’s a same-day inspection or 24/7 emergency assistance, we’re ready to act quickly and efficiently. Our licensed and insured plumbers arrive fully equipped, explain the process clearly, and ensure you know exactly what to expect.

Thank you so much Isaac for an excellent job. Replaced shower, bath, washing machine, laundry with ceramic quater turn taps. Also replaced shower head. Very professional indeed. Punctual, polite, humble and efficient. I'm very satisfied with the impressive work. I would recommend Isaac from In House Plumbing for any of your plumbing works.
Me and my extended family have been using their services for nearly 2 and half years . In-house-plumbing is very friendly and experienced team.Even when me and my family was out of the country I emailed him about the problem in my investment property he went and fixed the problem.He is very trustworthy and reliable. We recommend their services.
Issac is possibly the best Plumber I have ever met and known in Glenwood and surrounding areas such as Parklea, Stanhope Garden, Kellyville, Rouse Hill, Bella Vista, Castle Hill etc etc. and the suburb list will go on… I looked everywhere but when I came in contact with Issac I realised that there are still some nice guys out there doing the finest plumbing work and most importantly, ON TIME!! Very thorough, honest, humble, well spoken, he became just like our family. I wish there was a way to give him more than Five Star.
Isaac turned up on time and did a professional and thorough job. I would definitely recommend him to family and friends and use his services again
Friendly, courteous and knowledgeable plumber. Turned up on time and worked out the best solution for our needs. The turn around was within 24 hours which is everything when it comes to hot water and multiple kids in the home. Isaac the plumber, considered the best way to approach things noting some specific needs including pets in the back yard. Highly recommend this service. I'm a very happy customer. Thanks Isaac.
Isaac was amazing today. Couldn’t have asked for any better service. He got to our place in 15mins when he knew it was an emergency and nothing was to much to ask at all. If you are looking for a fantastic, reliable, honest plumber, he is your man. I would highly recommend him to anyone in a heartbeat
Great service! Isaac from In house plumbing came to fix my hot water and replace a shower head. Everything was sorted and fixed quickly and even worked through the rain to get it done before Christmas.Everything was done with great finish and service. Thanks for coming by Isaac, great experience.

I have been a customer of Issac for 4 years and he has replaced hotwater system, taps and done a bathroom renovatioon for me. All very high quality work to my satisfaction. My new kitchen tap was installed surpurbly.
Isaac is extremely knowledgeable in his domain, highly professional and above all - a very humble person. He did following jobs at our house - replacing the whole stromwater pipeline, installing a new toilet, tap replacement and leaking tap repair. Everything he did was done with best perfection possible! I would highly recommend Isaac for all the plumbing jobs.
