Excavation for sewer works at a country house

Plumbing and drainage

Pipework and drainage, from meter to street

What lies behind the wall and under the ground has to last for decades. We install it as if it will stay on view.

Plumbing and drainage

Our installers handle water supply, waste and heating pipework in renovation and new build. Every system is pressure-tested before it is closed in, and we record the route on drawings.

For drainage we excavate, lay and connect in-house: from a new sewer connection to separated rainwater drainage and infiltration. A camera survey maps existing pipes first.
