If you’re concerned about overflow risk or water backing up, book an inspection and we’ll talk you through options and pricing on site.

Local Experience That Matches Sydney Conditions

Sydney storm events, leaf litter, and older drainage layouts can expose weak points fast. Our team works across Sydney and surrounding suburbs, so we’re used to the usual culprits: silt build-up, roots, broken sections, poor fall, crushed lines, and pit overflow in heavy rain. We focus on restoring safe flow first, then checking what caused the blockage so you’re not booking the same job again after the next downpour.

If there’s an urgent overflow or water entering the property, you can also route the job through our after-hours pathway via emergency support.

Practical Expertise For Stormwater Plumbing

Stormwater systems aren’t one-size-fits-all. The right fix depends on where the restriction is (pit, pipe run, junction, discharge point), what’s causing it (debris vs roots vs collapse), and how fragile the line is. We’ll explain what we’re seeing, what we recommend, and what we’d avoid, especially where aggressive clearing could damage older or already-cracked pipes.

If your symptoms overlap with indoor waste lines (slow internal drains, gurgling, recurring sink backups), it may be worth comparing with blocked drain plumbing so the right system gets treated.

Good company.
Were able to arrange tradesmen to come out at the time that suited us, which was next morning. We rang 4:00 pm the day prior.
Tradesman had ten years experience in domestic, industrial and high rise plumbing.
Excellent communication. Arrived on time promised .
Response from the owner:Thank you Robert for the great feedback! We’re glad we could arrange a time that suited you and that our tradesman met your expectations. We really appreciate you taking the time to share your experience.
Response from the owner:Thank you Daniel for the 5 Star review mate. We are a phone call way if needed. Cheers
Friendly staff and great service. Dealing with Suzie and Oscar to get a new hot water system was a breeze
Response from the owner:“Thanks for the great feedback! We’re glad we could help with your hot water service . Our goal is always fast, honest, and high-quality plumbing across Sydney. Appreciate your support!”
After several attempts at finding a good plumber that stands by their work I found the boys at Apex plumber in my letterbox via a fridge magnet.. We had several plumbers come out and charge us for keeping our toilet blocked.. Which I found appalling,however on the first attempt and at a reasonable price Oscar unblocked our toilet and have had no problems since.. I wish I found that fridge magnet earlier and saved myself some money from having unqualified,rogue plumbers charge us for work they could not complete.We also had a problem with drainage however Apex recommended that it was not necessary to outlay the money on that work at present . I thoroughly recommend Apex Plumbing with their experience and equipment to handle any job..
Response from the owner:Thank you for the review! We will ensure you that we will always do our best to provide you with the best service possible and make sure your plumbing issues are resolved in a timely manner.

Stormwater Drain Cleaning Options And When Each Makes Sense

Not every blockage should be attacked the same way. The right approach depends on how fragile the line is and what’s inside it. Typical pathways include:

If inspection suggests structural failure, long-term options may include repair or renewal. In some cases, trenchless solutions such as pipe relining may be worth discussing depending on access, pipe material, and damage pattern.

Problems we solve

Common Signs And Outcomes Of A Stormwater Blockage

Stormwater problems often look like “just a bit of water” until the system is overwhelmed. Common signs include:

Pit water staying high long after rain stops

Overflow near downpipes or along the lowest point of the yard

Water tracking toward garages, paths, or subfloor vents

Sediment build-up or leaf mats over grates

Recurring wet patches that never fully dry

Erosion or wash-out patterns after storms

Left unchecked, the outcomes can include soil movement, damage around footings, slippery surfaces, mould-prone damp areas, and repeated clean-up costs after each heavy rainfall event.

Authority Through Standards And Safe Work Practices

Stormwater work often sits alongside compliance expectations for plumbing and drainage work in NSW. We take a “do it properly once” approach: clear the immediate restriction, confirm the line is flowing as intended, and identify any structural or design issue that makes blockages more likely. Where the best long-term outcome needs repair rather than repeated clearing, we’ll outline the trade-offs in plain English.

What You Get With Our Storm Water Drainage Solutions

If your stormwater system is struggling, you want two things: a reliable clear and confidence it won’t immediately recur. Our service is built around both.

When needed, we can also coordinate complementary plumbing support such as targeted leak detection if water ingress symptoms suggest multiple sources.

Who This Service Is For

Stormwater issues don’t only show up in extreme weather. This service is suited to:

If you’re unsure whether it’s stormwater or wastewater, start with the symptoms and we’ll guide you from there.

Trust Built On Clear Scope And Transparent Pricing

You’ll know what’s included before the work proceeds. Apex Plumbing Services pricing is fixed and quoted on site once the problem is assessed, with straightforward communication about what we can resolve today and what may need follow-up. If the job indicates underlying pipe damage, we’ll show you the options and likely outcomes so you can choose based on budget, disruption, and risk tolerance.

3
Select the safest clearing method
based on pipe condition and blockage type.

Frequently Asked Questions

FAQs About Blocked Storm Water Drains in Sydney

What causes blocked stormwater drains most often?

Most stormwater blockages come from leaf litter, silt, and debris building up at pits, grates, and junction points—especially after wind and heavy rain. Over time, that build-up catches more debris and reduces flow. We’ll identify whether it’s a simple debris restriction or a sign of something deeper (like roots or pipe damage) before recommending the right fix.

How do I know if it’s stormwater or sewer drainage?

Stormwater issues usually show up outdoors: pit overflow, pooling water, soggy areas, or downpipe backups during rain. Sewer or wastewater problems often show indoors: slow sinks, gurgling, toilet issues, or smells. Sometimes both can coexist on older properties. If symptoms overlap, we’ll help confirm which system is affected so the right line gets cleared first.

Is a storm water drain blocked an emergency?

It can be, depending on overflow location and weather. If water is heading toward the home, garage, or subfloor vents, or if a pit is actively overflowing during storms, it’s worth treating as urgent. We can advise immediate safety steps and arrange attendance when required. For urgent issues, request help via our contact page.

Can I clear a blocked stormwater drain myself?

Light surface debris at grates can be safely removed in many cases, but deeper blockages can be risky without the right tools and know-how. Over-clearing can damage fragile pipes or push debris further into the line. If you’ve cleared visible debris and water still won’t drain properly, a professional assessment is the safer next step.

Do you offer after-hours help for stormwater problems?

Yes. Apex Plumbing Services can assist 24 hours if required, including after-hours call-outs when stormwater issues are creating immediate risk. Availability can vary with demand during major weather events, so it’s best to call early if you’re seeing overflow or water entry concerns.

How much does stormwater drain cleaning cost in Sydney?

Pricing depends on access, blockage severity, and whether the issue is a straightforward clear or linked to structural damage. Apex Plumbing Services provides fixed pricing that’s quoted on site once we assess the system. If follow-up repairs are recommended, we’ll explain options and likely outcomes so you can choose based on budget and disruption tolerance.

How long does it take to clear a stormwater blockage?

Some blockages can be resolved in a single visit, while others take longer if the line is heavily silted, root-affected, or damaged. We’ll give you a realistic timing expectation once we’ve seen access points and confirmed what’s causing the restriction. If additional work is needed, we’ll outline the staging rather than guessing upfront.

What if the blockage keeps coming back?

Repeat blockages usually mean the underlying cause wasn’t removed—common examples include root ingress, poor fall, crushed sections, or a pit that constantly collects debris. We’ll look for the “why” during the visit and talk through prevention steps. If there’s structural failure, we may recommend repair or renewal options instead of repeated clearing.

Can tree roots block stormwater pipes?

Yes. Roots can enter joints or cracks and create a net that traps debris, leading to recurring blockages. Clearing may restore flow temporarily, but if roots are actively intruding, a longer-term plan is usually needed. We’ll explain what we’re seeing and the practical next steps, including repair pathways where appropriate.

Do you work with strata and insurance-related plumbing?

Apex Plumbing Services regularly supports a range of property types and can communicate clearly for strata and managed properties. If documentation, access coordination, or staged work is needed, we’ll outline the process and scope so you can plan approvals and timing with fewer surprises.

What information do you need to start the job?

To book efficiently, it helps to share the address/suburb, what you’re seeing (overflow location, pooling, downpipe backup), when it happens (only during rain or all the time), and any recent changes (tree growth, landscaping, renovations). Photos of pits or pooling areas can also help, but they’re not required. You can start the process via booking and enquiries.

Can I switch plumbers mid-job in Sydney?

You can, but it’s best to get clarity on what’s already been done and what’s still pending so you don’t pay twice for the same diagnosis. If you’re taking over a partially completed stormwater job, we’ll review the site conditions, confirm the current status, and then quote the safest next steps based on what’s actually required.

What’s the difference between a licensed and unlicensed plumber?

A licensed plumber meets NSW licensing requirements for regulated plumbing and drainage work. Using an unlicensed provider can increase risk around compliance, workmanship, and accountability if issues arise later. If you ever want to verify credentials, you can check a contractor licence through official NSW channels before engaging a provider.

Do you service blocked stormwater drains near me?

If you’re in Sydney or surrounding suburbs, there’s a good chance we can help. The quickest way to confirm coverage and availability is to send your suburb and a brief description of the problem through our booking form, and we’ll advise the next best step.
