Water bubble forming on the ceilingDelft, South Holland

A sagging, paint-bubble on the ceiling that feels soft or squishy is trapped water pooling above the drywall. The source is almost always a plumbing leak, a roof leak, or condensation from HVAC ducts on the floor above. Left alone the bubble will grow, the drywall will collapse, and the water may damage wiring, insulation, and structural framing. A plumber can trace the leak, stop the water source, and coordinate drywall repair to get your ceiling back to normal.

Why this is common in Delft

Plumbers in Delft deal with hard-water limescale, ageing pipework in the older stock, and — on the wet Dutch subsoil — drainage, cellar pumps and damp. Gas and water work runs through recognised installers (InstallQ).
