A guide for Hervey Bay homeowners on dealing with water-damaged plaster ceilings, from small stains to sagging sheets.
Summer storms and the odd blocked gutter mean water-stained ceilings are one of the most common plaster jobs we see around the Fraser Coast. Here's how to tell what your ceiling needs.
There's no point repairing plaster until the source is fixed. Check the roof, gutters, valleys and any plumbing above the ceiling. Once it's dry, the damage can be assessed properly.
If the plaster is still firm and flat, a stain can usually be sealed with a stain-blocking primer and repainted. Ordinary paint won't hide water marks for long, so the right primer matters.
If the sheet feels soft or the joints have opened up, the damaged section needs cutting out and replacing. A good patch is joined, set and sanded so you can't see it once painted. See our ceiling repairs page.
A sagging ceiling can come down without warning, especially if it has absorbed water. Keep people out of the room and get it looked at quickly. Older homes can also have sagging caused by failed adhesive rather than water. Our water damage plaster service covers both.
If the water came in through an external wall rather than the roof, check the outside too. On the outside of the house, cracked or tired masonry walls usually need rendering work rather than plaster, and sealing them stops the problem coming back.
