This is a practical page about full property rewires on a victorian terrace in Mountain Ash — no stock photography claims, no invented statistics. Cable routing is planned around the front bay, the hallway and the ceiling voids — not the walls. Local housing here is largely Edwardian terraces in Penrhiwceiber with shared party walls, and that shapes both the likely findings and the realistic scope. Diary planned for the access is the part worth confirming rather than assuming.
A fair amount of this work is preparation: confirming cable routing planned around solid 9-inch brick with plaster-on-lath, planning the route, agreeing what happens if something unexpected appears behind the plaster. Which is why the price follows the test rather than the other way round. The Mountain Ash version of this job is shaped by the local housing: Edwardian terraces in Penrhiwceiber with shared party walls.
