Karrinyup is an established suburb that has matured around the original 1960s and 1970s estate layout, with the Karrinyup Shopping Centre redevelopment and steady residential infill changing parts of the suburb significantly over the past decade. Drainage in Karrinyup reflects this mix of original infrastructure and newer additions. Drains Plus is a Perth drainage specialist with more than 20,000 jobs cleared across the metro, and this page covers how we approach drainage work in Karrinyup.
Karrinyup sits within the City of Stirling, which manages stormwater and kerbside drainage infrastructure. The original housing stock dates from the 1960s and 1970s, with mature street trees and established landscaping that has been growing alongside the original drain runs for fifty years or more. Recent years have brought significant infill activity, with original homes giving way to newer single and dual occupancy builds. Soils across Karrinyup are predominantly Spearwood sand. The original sewer lines on older homes are typically a mix of clay and early generation PVC, with newer homes and renovations using modern PVC throughout. Stormwater drainage runs to City of Stirling pits and gullies at the kerb.
Tree root intrusion is the dominant problem on older Karrinyup properties. The combination of mature street and yard trees, established public verges and aged clay or early PVC joints gives roots the access points they need to grow into the line. We see this most often as recurring blockages that return a few months after clearing. On newer infill builds, the problem profile is different. We see crushed or misaligned lines under driveways and paved areas where the original drain run was retained but works above it have changed the load on the ground. Stormwater issues tend to involve gullies and pits clogging with sand, leaves and bark mulch, particularly around mature verge trees through autumn. CCTV inspection is the right starting point on almost every recurring case, because it shows us not just where the obstruction is but what the line itself looks like.
Drains Plus operates from Greenwood, a short drive from Karrinyup. For most call outs we can have a plumber on site the same day, and emergency call outs are covered around the clock. We are a single location business with a single Google profile, so when you book through us you are dealing directly with the team that will arrive at your address. Most blocked drain work is covered by our fixed price guarantee, and a free plumbing health check is included on every job. If we cannot clear the drain, our service is free.
We service Karrinyup as part of our wider coverage of the Perth northern suburbs. Nearby suburbs we cover include:
If you are based outside these areas, our full service area covers the Perth northern suburbs across four local government areas.
Repeated blockages at the same location are almost always a sign of an underlying issue in the line itself, most often root intrusion or a section that has cracked or separated at a joint. Clearing solves the symptom but not the cause. A CCTV inspection identifies what is happening so we can talk about the right long term answer.
Yes, particularly if you are planning paving, decking, a pool, or any work over the existing drain runs. A pre renovation CCTV inspection gives you a clear baseline of what is in the ground, and it is far cheaper to deal with a marginal line before the works go in than after.
We provide a free quote before any work starts. Most blocked drain work is covered by our fixed price guarantee, so you know what the job will cost before we begin. A free plumbing health check is included on every visit.
Yes. General plumbers cover a broad range of work, from hot water units to bathroom renovations. We specialise in drainage. That means our team sees the same drainage problems repeatedly, and we carry CCTV camera and high pressure jetting equipment on every job. For drain specific work, a specialist is usually faster and more accurate than a general plumber.
