We recently attended a stormwater issue in Castle Hill after the client noticed water leaking into their living room whenever it rained.

Rather than guessing at the cause, we used a CCTV drain camera to trace the problem back to a section of pipe running under the garden bed. This let us dig in exactly the right spot instead of opening up more of the yard than necessary.

Once excavated, we found the real cause: an old clay stormwater pipe had cracked, and tree roots had grown into the crack, gradually blocking the pipe and forcing water back toward the house instead of away from it. It's a common but often hidden cause of leaks like this, especially in older clay pipework.

We removed the damaged, root-affected section and replaced it with new PVC pipe and an inspection point, before backfilling and reinstating the area. As requested by the customer, the surrounding stonework wasn't replaced — we reinstated with a concrete patch around the new inspection point instead.
