To avoid mould after a leak, stop the water source first, then dry the area within 24 to 48 hours using ventilation, fans and the AC, remove soaked materials like carpets and gypsum that cannot dry, clean surfaces with a suitable mould treatment and monitor moisture until readings return to normal before repainting.
Stop the source
No drying works while water is still arriving. Get the leak fixed first: water leak repair.
Dry fast
Mould can start within a day or two in warm conditions. Open cupboards, pull furniture away from walls, run fans and keep the AC on to reduce humidity. In Dubai's humid coastal months, a dehumidifier helps a lot.
Remove what will not dry
Soaked carpet underlay, swollen MDF cabinet bases and saturated gypsum board rarely recover. Replacing them is cheaper than living with hidden mould.
Clean and monitor
Clean hard surfaces with a mould-specific cleaner and wear gloves and a mask. Check moisture with a meter over the following weeks. Only repaint when it is dry, using a stain-blocking primer.
When mould keeps returning
Recurring mould means ongoing moisture: a second leak, seepage from a bathroom, or condensation. Book seepage leak detection.
Dubai homeowner checklist
- Run the AC and a dehumidifier to keep humidity down while drying.
- Never paint over damp plaster.
- Clean mould with a dedicated cleaner, gloves and a mask.
- Recheck moisture before redecorating.
