$0 call-out fee — any hour, any day · Available 24/7

Hornsby emergencies are shaped by the bush. Many homes back onto steep sandstone gullies under big eucalypts, so storms bring overflowing gutters and stormwater running where it shouldn't, and sewer lines often run through the back of the block towards the gully, under trees. Near the station, it is apartment work: shared services and strata.

Repairing a water pipe a demolition crew put through during a bathroom strip-out. Trade damage is one of the more common reasons we get called out mid-job.

A concealed leak found in a Sydney office. By the time it shows on the floor it has usually been running for weeks.

Eucalypts shed leaves and bark all year. A gutter that has filled overflows into the eaves in heavy rain, and debris washed into the downpipes blocks the stormwater line below.

On a steep block, water off the roof has to be carried down the slope in a controlled way. When a line breaks or its outlet scours out, the water can end up under the house instead.

Where the sewer runs away from the street through gardens and established trees, roots work into it and hard access slows everything down. A camera inspection after clearing shows where the damage is.

Common Questions

Check nothing electrical is near the water, then call us. On a sloping Hornsby block it is usually stormwater from above that is not being collected or is escaping a broken line. We trace where it is coming from before recommending anything.
