Stormwater Drainage Repairs Sutherland Shire
Water Should Drain, Not Pool..
Most stormwater systems only get noticed when they fail… a flooded yard, water pooling against the house, or a drain that can’t keep up during heavy rain. Monty’s Plumbing designs, installs and repairs stormwater drainage, rainwater systems, ag lines and absorption pits for homes and renovations right across the Sutherland Shire.
After 25 years working drainage across the Shire, we know which properties are prone to pooling, runoff and overflow and how to actually fix it, not just move the problem somewhere else.

Stormwater problems usually only show up properly when it rains, here’s what we get called out for most across the Shire.

Water Pooling in the Yard
If certain spots in your yard stay wet or pool for days after rain, your stormwater system likely isn’t draining the way it should, or wasn’t designed for how the property actually sits.
Water Pooling Against the House
Water collecting near your foundations or under the house is one we treat seriously, since it can lead to damp, mould or structural issues if it’s left unaddressed.
Overflowing Stormwater Pits or Drains
Pits and drains that overflow during heavy rain are usually a sign of a blockage, undersized pipe, or a system that’s no longer coping with runoff from the property.
Broken or Disconnected Downpipes

Stormwater Overflowing?

When heavy rain hits and your stormwater can’t keep up, it can’t wait for a quiet week. Monty’s Plumbing offers 24/7 emergency callouts across the Sutherland Shire, so if water’s pooling or overflowing where it shouldn’t be, we can get to you fast.

Why Trust Us With Your Stormwater Drainage
Done Right The First Time
Stormwater issues are rarely about just one pipe or pit. Here’s how we make sure the whole system actually works.
We Map How Water Moves on Your Property
Before we touch anything, we look at how water actually flows across your block, so the fix addresses the real problem, not just the spot where it's pooling.
Built for Real Rainfall, Not Just Compliance
We design and install drainage that's built to handle genuine heavy rain events across the Shire, not just the minimum needed to pass an inspection.
25 Years Solving Drainage Across the Shire
We've worked on stormwater systems across every type of block in the Sutherland Shire, from low lying properties to steep blocks with serious runoff.
Stormwater Services We Provide
Every Stormwater Job,
Handled Properly!
Every Stormwater Job, Handled Properly!
Leaves, dirt and debris build up over time and block stormwater pipes and pits. We clear these properly and check the line to prevent it happening again.
A disconnected or poorly positioned downpipe can undo the rest of your drainage system. We connect, repair and reroute downpipes so water actually goes where it should.
We install new stormwater pipework for renovations, extensions and new builds, designed to handle the property’s actual runoff, not just the minimum requirement.
Ag lines manage groundwater and subsurface moisture around your property. We install and repair these to keep water moving away from your home, not pooling underneath it.
Absorption pits help manage stormwater on properties where it can’t be discharged directly to the street. We install and maintain pits sized correctly for your block.
We plumb in rainwater tanks for household use, including overflow management, so excess water is directed safely rather than left to pool.

Blocked Drains In Sutherland
We Understand The Shires Stormwater
The Sutherland Shire isn’t flat, and that matters when it comes to stormwater. Sloped blocks, sandy soil in some areas, and heavy seasonal rain all affect how water moves across a property, and a system that works fine on one block can fail completely on another just down the road.
Monty’s Plumbing has designed, installed and repaired stormwater systems across the Shire for over 25 years, so we don’t just guess at how your property will handle the next downpour. We’ve already seen how the ground around here behaves.
Client Reviews
Happy Clients, Always.
Trustindex verifies that the original source of the review is Google. Ryan was professional, punctual and super efficient. Minor repairs sorted in less than 24 hours, as we didn't need same day service despite it being offered. I would trust Ryan and the team to give honest and reliable advice and service any day of the week. Thank you!Posted on Google Kimberley RawlingsTrustindex verifies that the original source of the review is Google. We had a drain blockage. Ryan turned up the next day, on time and charged exactly what he said he would. Communication was great throughout the job explaining what caused the blockage and showing the cleared pipes through his camera. We will definitely use Ryan again. Highly recommend.Posted on Google Clair SpicerTrustindex verifies that the original source of the review is Google. Absolutely outstanding service! ⭐⭐⭐⭐⭐ We had a serious emergency with sewage backing up through our bathroom drains and flooding towards the living room — it was a very stressful situation.

You can tell they know exactly what they’re doing. They not only fixed the issue but also prevented what could have been a much bigger disaster. Honestly, they saved us.

Thank you so much to Ryan and the team from Monty's Plumbing. We had Ryan and team get us a second quote for some plumbing services we needed to our house, and their quote was half the price of the initial quote. From start to finish, Ryan and team were professional, helpful, and fixed our plumbing issues completely. I wouldn't hesitate to recommend them. Thank you so much for all the work you did to our apartment.Posted on Google Mary KonstantopoulosTrustindex verifies that the original source of the review is Google. Ryan and his team have done an excellent job. This is the second time I have had to call on them. It is easy to do a good job. But of more importance is how to respond when there has been a "problem". Ryan has responded quickly and perfectly. This type of action is what sets Ryan apart from being good to being excellent. Well Done.Posted on Google Robert HillTrustindex verifies that the original source of the review is Google. I had Ryan from Monty’s plumbing replace some tap fittings in my home, he was very thorough and did the job to perfection and was very efficient. I would highly recommend him for any of your plumbing needs.Posted on Google jade lillingtonTrustindex verifies that the original source of the review is Google. I have used Monty's plumbing several times over the years, Ryan and his team are dedicated to carrying out high quality work which is why we use them. He and his team have carried out bathroom renovations, kitchen renovation works, maintenance jobs. Ryan and Jermaine got me out of a pickle last year when I uncovered a deck to find a boggy swamp, I called Ryan and he and Jermaine were there the next day to solve the problem. He installed a new drain with an electric pump to remove the water. If you are after a plumber, you would be hard pressed to find one as knowledgeable as Ryan.Posted on Google George SewellTrustindex verifies that the original source of the review is Google. Ryan and the team at Monty’s plumbing were nothing short of exceptional. They did all plumbing tasks for our home extension and renovation (kitchen, bathrooms, laundry etc). They were facilitating, provided good feedback and original ideas. I would not hesitate to use Ryan again. He is the Batman of plumbing!Posted on Google Dillon NarsiTrustindex verifies that the original source of the review is Google. Ryan was incredibly prompt, friendly and didn’t settle until the job was 110% done. He went over and above to make sure our issue was fixed and our ageing sewer was in good stead for years to come. Highly recommend Monty’s plumbing!Posted on Google Dave Standen
Stormwater Drainage FAQS
No Stormwater Question We Cant Answer!
Why does water keep pooling in the same spot in my yard?
This usually points to a drainage or grading issue rather than a one off blockage. We’ll assess how water is actually moving across your property to find the real cause.
What's the difference between an ag line and a stormwater pipe?
An ag line manages groundwater and moisture underground, while a stormwater pipe carries surface water away from your property. Many homes need both working properly together.
Do I need an absorption pit on my property?
It depends on your block and whether stormwater can be discharged directly to the street. We can assess your property and let you know what’s required.
Can you fix drainage issues without major excavation?
In many cases, yes. We’ll always explain what’s actually needed for your situation before any work begins, rather than assuming the worst case option.
