Water damage plaster repairs in Woolwich flats and houses — damaged board cut out, replaced, taped and skimmed to match the rest of the ceiling.
A leak from the flat above is the single most common plastering job in Woolwich, and it is usually more urgent than it looks. Wet plasterboard loses its strength and stays weak even after it dries, so a stained ceiling that feels firm today can go later. It also needs to be genuinely dry before anything new goes up.
In the Royal Arsenal blocks and the newer riverside buildings, ceilings are often fire-rated board, so a repair is not just a patch: the replacement has to match the rating of what was there. In the older Plumstead and Charlton conversions a leak can also run along a joist and show up a room away from where it started.
Board that is still damp will blow the new skim off it. We check with a meter rather than by eye and will wait rather than come back.
Back to sound material and to the joists either side, so the patch is fixed to something rather than floating.
Jointed properly and the finish feathered out, so the repair does not read as a rectangle when the light crosses it.
Photographs and a written scope if it is going through insurance or to the freeholder. It costs us nothing and it saves you an argument.
Where the damaged ceiling is fire-rated board, the replacement is the same specification, so the repair does not quietly weaken the separation between flats.
The ceiling is checked well beyond the stain, because water spreads along joists and the softened board is often wider than the mark suggests.

Only if the ceiling was not properly dry or not sealed. Water stains carry tannins that bleed through emulsion indefinitely - we seal with a stain block before skimming or painting, which is the step most often skipped.
A patch is fine on a plasterboard ceiling and usually invisible once painted across. On a small room, or where the damage is in the middle of a plain ceiling, skimming the whole thing is sometimes only a little more and removes any risk of a shadow.
Usually their insurance or the freeholder, depending on the lease. We are not going to advise you on that, but we will give you a written scope and photographs that make the claim straightforward.
Once the leak is fixed and the board and timbers are dry, which can be days for a small drip or a few weeks after a big one. The ceiling is checked with a moisture meter rather than repaired on a guess.
A small dry stain on firm board usually is. A ceiling that has gone soft, sags, or still has water coming through should be kept clear underneath, with the water turned off at the source if you can find it.
