Replacing risers without moving out: how it runs day by day
Risers are the most postponed repair in apartment buildings — for fear of intrusion into flats. In practice, replacing one shaft takes 3–5 days. Here's the real procedure.
Water and drainage risers from the sixties and seventies are past their service life. Yet their replacement is the most postponed repair of all — boards fear owners' reactions to work inside flats. Experience from dozens of buildings shows the worry is bigger than the reality.
A schedule per shaft, not per building
Work is planned shaft by shaft. In one riser (the vertical stack of flats), the complete replacement of water, drainage and possibly gas takes 3 to 5 working days. Water is shut off only during working hours and only in that shaft — the rest of the building runs normally.
What happens inside a flat
Day one, the installation shaft in the core is opened (usually bathroom or WC) and old pipes are removed. Days two and three, new risers and connections are installed. The last day brings the pressure test, closing up and cleaning. Residents only need to be home briefly — to open up and sign off.
Why combine it with bathroom renovation
An opened core is the perfect opportunity for owners planning a new bathroom — it saves demolishing twice. We offer individual bathroom renovations coordinated with the riser replacement; the building follows one schedule and each owner picks the scope for their flat.
