Stormwater Repairs in Illawarra

Stormwater repairs involve fixing underground drainage systems that carry rainwater from roof downpipes, surface drains and paved areas to the council stormwater system or a legal point of discharge. In Illawarra, stormwater repairs cost $300-$5,000+ depending on the issue. Clearing a blocked stormwater drain using high-pressure jetting costs $200-$500. CCTV pipe inspection to locate the problem costs $200-$350. Pipe relining — inserting a resin liner to seal cracks, root entry points and joint failures without excavation — costs $150-$300 per lineal metre. Traditional excavation and section replacement costs $1,500-$4,000 depending on pipe depth, length, access and surface restoration (concrete, pavers, garden). New stormwater installation from downpipes to council connection costs $2,000-$6,000. Common stormwater problems in Illawarra include collapsed clay and concrete pipes from age and ground movement, tree root intrusion, blockages from silt, debris and construction waste, disconnected downpipes discharging onto the ground, and undersized drains overwhelmed by heavy coastal rainfall. Failing stormwater drainage causes foundation erosion, subsidence, damp subfloors, yard flooding and potential structural damage to the property.
