Downpipe Replacement in Illawarra
Professional downpipe replacement across Wollongong, Kiama, Shellharbour and the greater Illawarra region. New Colorbond downpipes, upsizing for better flow, old pipe removal and stormwater connection.
Downpipe replacement involves removing old, corroded or undersized downpipes and installing new ones — typically in Colorbond steel — to properly drain rainwater from gutters to ground-level stormwater. In Illawarra, downpipe replacement costs $200-$450 per downpipe installed, including removal of the old pipe, new Colorbond pipe, offsets at the eave, wall straps and connection to both the gutter outlet and stormwater drain. Upsizing from the older 75mm diameter to 90mm round improves capacity by approximately 40% and is recommended for Illawarra's heavy rainfall events — this adds $30-$50 per pipe. A typical home has 4-8 downpipes, putting full replacement at $1,000-$3,000. Where stormwater connections don't exist (common on older homes), new underground connections cost $200-$500 extra per downpipe. Downpipe replacement is often done alongside gutter replacement for a complete system upgrade, but can be done independently when gutters are still sound. Correctly sized and connected downpipes prevent gutter overflow, wall staining, foundation erosion and damp problems.

These are typical price ranges for the Illawarra and NSW, drawn from published 2026 industry pricing data — not a quote, and not our fixed prices. What your job actually costs depends on access, the age and condition of the plumbing, parts, and whether it is after hours. We give you a fixed price before we start work, so you are never guessing.
