|Questions to ask
||Bath or shower, check rough size. Is there a leak?
can leak from a number of places. The most common is through a
damaged mastic seal, usually caused through movement of a bath
or shower tray. This can generally be put right through thoroughly
removing the existing mastic and replacing it. Shower trays, particularly
the older lightweight versions flex and damage the mastic seal
or sometimes crack, particularly around the drain point. Stone
cast or firmer resin trays are better. Showers can also sustain
pipe leaks and water can get behind tiles if grout becomes loose.
It is the removal of the old sealant which
takes the most time. When sealant has been replaced don't use
the bath or shower for 24 hours. It is worth mentioning three
- sealant is not a filler. If the gap
is more than a couple of millimetres then something needs adjusting
- if the bath or shower tray are not firmly
fixed then the seal will not be long lasting
- sealant which is discoloured can be
cleaned in many cases. Plain bleach soaked into a string of
toilet paper on the sealant and left over night works wonders
- test an area first though!
