This photo shows a recent shower repair. The bottom half of the shower cubicle was leaking.
This is because water was getting in behind the tile grout causing a leak.
Plasterboard was subsequently damaged and rotten.
The tiles and plasterboard was removed. The tiles were cleaned up ready for re-use to keep the project to a minimal cost for the customer.
New noggins (baton wood) were installed, new plasterboard was fitted.
The corners and joins to existing tiles were sealed with silicon.
This was then re-tiled with waterproof tile adhesive and re-grouted and resealed.
The end result was that it was a good as new!!
So if you are getting leaks from your shower it could be due to a similar problem and not a big project to fix.
This cost was only £280 including all labour and materials which is nothing compared to the costs involved in neglecting a small shower leak that causes a downstairs ceiling to collapse or need replacing.
The typical cost of replacing a ceiling downstairs from damage caused by an upstairs shower is usually at least twice as much!
