Hull & East Yorkshire
A stain on the ceiling is the visible end of water that has already spread across the joists above. Whether the ceiling can stay depends on what it's made of and how wet it got.
Plasterboard, in most homes built or renovated since the 1960s, is light and cheap to replace. Once soaked it softens and sags, and it's usually replaced rather than dried.
Lath and plaster, in many pre-war Hull houses, is heavy: thick lime plaster pushed through timber laths. It can survive a small leak and dry in place, but once the plaster loses its key it can come down in large pieces without much warning. We check it before anyone works under it.
Replacing a ceiling without drying the joists and floor above it traps the damp, and the stain or mould comes back. We take readings in the void and the floor above, dry them first, and then repair the ceiling.
If the source isn't obvious, it's usually the bathroom or a tank above, a radiator pipe under the floor, or the roof. Our ceiling leak page covers tracing it, and roof leaks covers water from the top of the house.
To see what a leak like this usually costs to put right, and what you'd pay after your excess, use our water damage cost estimator.
Mould starts growing within 24 to 48 hours of a leak. The sooner drying starts, the less damage and the lower the cost.
Call 01482 736003Yes. It can come down suddenly with the weight of water. Keep people out of the room and ring us.
Small stains on a sound ceiling can be dried and painted with a stain blocker. Soaked plasterboard and loose lath and plaster usually need replacing.
Either the leak is still active, or the ceiling and void weren't fully dry. Fix the source and dry it properly first.
If a sudden leak caused it, usually yes, as escape of water. Slow leaks from worn seals may be excluded.
Ring us and we'll make it safe.
