It’s not surprising that the worst effects of dampness are often seen in the bathroom. Hot water from the shower causes steam that condenses on walls, damp towels are left lying on the floor by overworked teenagers, and puddles of water are commonplace. Here we look at how to repair a water-damaged wall in the bathroom.
What causes water-damaged walls in the bathroom?
Apart from wet feet, steamy showers, and unruly teenagers – problems that can be reduced by bath mats, open windows, and a parenting strategy that has yet to be discovered – the most common causes of bathroom wall water-damage are:
- A poorly fitted shower doorjamb
- Improperly sealed edges on the bathtub
If left unchecked, you’ll find that the water eventually soaks into walls, trims, wall studs and floor plates. When this happens, a simple task of refitting tub seals or shower doors becomes a major job. You’ll need to replace drywall and wood before the mold starts spreading further.
The 5 step process to repair a water-damaged wall in the bathroom
- Where the wall is damaged, remove trim through to the nearest non-damaged stud. Now mark the area to be removed, by drawing a vertical line half way across the good stud and a horizontal line from this line toward the tub. The horizontal line must be above the water-damaged area of drywall.
- Cut along these lines, and remove the damaged area. Make sure you also remove any screws or nails that remain in place.
- If the studs or plates that are now exposed are damaged, you’ll need to remove and replace these, too. If the damage of these has spread further, which is very possible, you will need to remove more drywall to replace the damaged studs and plates.
- Cut new drywall (of the same thickness as the existing) to fit the open space, and fix with drywall screws. Make good all seams and screw holes by applying drywall mud and then taping over, before applying a final layer of drywall mud. Sand to a smooth finish when dry. Repeat two or three times until no joins or bumps are perceptible.
- Install new trim, and use silicon to seal the edge where the tub meets the drywall.
Make sure you treat the cause and not the symptom
A water-damaged wall in the bathroom is always a symptom of a bigger problem. To make sure your bathroom doesn’t suffer more water damage, you’ll need to fix the cause – that may require new silicon to properly seal the tub edges, or perhaps a vent needs cleaning or replacing to ensure good air flow that prevents condensation.
