When drains collapse, crack, or become overrun with tree roots, sometimes the only effective fix is to expose the line and replace it. Open-trench excavation remains the most reliable way to repair severely damaged stormwater and sewer pipes, restoring full flow and long-term stability to your property.

At CS Plumbing & Drainage Services, we provide licensed excavation and repair services for homes, businesses, and strata-managed properties across Wollongong and the Illawarra.
