Frequently Asked Questions

How much does stormwater plumbing cost in Sydney?

Stormwater plumbing costs can vary depending on the size of your property and the complexity of the issue. For example, a simple stormwater pipe repair may be more affordable than installing a full stormwater pit or replacing large sections of underground drains.
At In House Plumbing, we provide clear, upfront quotes with no hidden fees so you know exactly what you’re paying for. Our goal is to offer solutions that fit your budget while ensuring long-term protection for your home or business.

Do I need council approval for stormwater drainage repairs?

In many cases, stormwater drainage repairs must comply with local council regulations. This is especially true for new installations, major upgrades, or commercial properties that require certification.
We handle the compliance process for you, ensuring all work meets council and strata requirements. This saves you time, prevents costly fines, and guarantees your property remains safe and compliant.

Why does my backyard flood after heavy rain?

Backyard flooding is often caused by blocked drains, broken stormwater pipes, or poor system design. Heavy rain can overwhelm your drainage, leading to water pooling around foundations and damaging gardens or outdoor spaces.
Our licensed plumbers can quickly diagnose the cause of flooding and provide practical solutions, from clearing blockages to installing new drainage systems. We’ll ensure your stormwater system can handle even the heaviest downpours.

Can a plumber fix stormwater drainage problems?

Yes, a licensed stormwater compliance plumber is the right professional to call for blocked or broken stormwater systems. Unlike general repairs, stormwater drainage work requires specialist knowledge to ensure compliance and long-lasting results.
At In House Plumbing, we use modern tools and techniques to repair stormwater pipes, clean drains, and install pits. We provide durable solutions that keep your system running effectively for years to come.

Will your solution prevent future blockages and flooding?

Absolutely. Our approach focuses on long-term stormwater plumbing solutions, not just temporary fixes. By addressing the root cause of stormwater issues — whether it’s tree roots, collapsed pipes, or poor design — we ensure your system works reliably.
We also offer ongoing stormwater system maintenance to keep your drains clear and compliant year-round. With regular checks, you can avoid unexpected flooding and enjoy peace of mind no matter the weather.
