First fix pipework in copper or plastic, internal soil stacks replaced or rerouted, all to current building regulations.
Behind the wall is where bathrooms succeed or fail. Pipework run at the wrong gradient, joints buried that should be accessible, copper run too tight to a hot pipe - these are the problems that come back to bite a household three winters later. We run first fix to a standard the second fix can sit on top of without surprises.
Internal soil stacks are the most common rework on older Cardiff terraces. Cast-iron stacks have a working life and tend to need replacing in the renovation rather than after it. We replace in plastic with proper bracing, take the old cast iron out tidily, and reroute the boss connections so the new bathroom layout works.
New installs, full rip-outs of failed pipework, gradient corrections on slow-running wastes, soil stack replacement and reroutes, vent terminations through the roof.
Every job is run the same way: same team, same trades, same approach. The notes below are how we think about pipework & soil stacks specifically.
Copper for visible runs and where insurance specifies it, plastic for hidden under-floor runs. Always pressure-tested.
Cast iron taken out cleanly, plastic in with the right brackets and falls. Boss connections planned around new layout.
15mm fall per metre on a 40mm waste, no exceptions. Slow-running wastes after a renovation are almost always a gradient problem.
Through the roof, properly flashed, no air ingress at the joints. Some routes use AAVs internally where appropriate.
Pulled from the last few months across Cardiff, Newport and the boroughs. Hover for a one-line note on the project.
Call Simon for an initial chat, or send a couple of photos of the space and Sycamore will come back with a quote the same week.
A few photos and a sketch of the room is usually enough for a first quote. For anything structural or tricky, we come and look.
