Replacing bath sealant
HomeForce’s Edinburgh Handymen have replaced bath silicone in the homes of literally hundreds of customers in Edinburgh since our establishment in 2004. However, replacement of bath or shower silicone is not always the best way ahead.
Replacing bath sealant or shower sealant is something that most people can do if they have the right tools, some time and a little bit of patience.  
However, it’s not always necessary to remove old silicone and replace it with new. If the silicone (or tile grout) is discoloured with black mould (or has taken on an orange hue from soap residue) then it may be better (and cheaper) to clean it rather than replace it. 
If you are in doubt you can always call upon our Edinburgh Handyman Service to find someone with experience of replacing bathroom silicone.
The result of leaks caused by poorly applied silicon can be far more expensive and time consuming than the money saved by doing it yourself or paying someone who doesn’t know what they are doing.
When should silicone be replaced?

If silicone is old, becoming dry and cracked or if you can see it coming away from tiles, or the bath or shower edge. 

Leaks may not be apparent if you live on a ground floor or basement so it’s worth checking the silicone closely reasonably regularly (once or twice a year). 

When do you NOT need to replace silicone?

People often think that silicone needs to be replaced when there is a build up of black mould on the silicone and grout. This is not always the case. 

Often tile grout and silicone can be restored to pristine white by applying strong, thick bleach, leaving it for 15 – 20 mins and then wiping off with a warm cloth.  Don't scrub it with a brush and be sure to use a thick bleach that won't just run off.

If it doesn’t work first time try leaving the bleach on for longer. 

At the end of the day black mould is a bacteria and bleach is designed to kill bacteria


Preventing black mould on grout and silicone

Prevention is, of course, better than a cure so stopping black mould from forming in your bathroom is always good, not least because, if left unchecked, black mould can have detrimental effects on your or your family’s health. 

To stop the build up of black mould in your bathroom ensure the room is well ventilated. Install (and use) a good extractor fan or open a window during and after baths and showers. If you have a shower cubicle leave the door open after your shower and even wipe down the edge of the shower / bath. Finally, try to avoid leaving wet sponges and cloths in permanent contact with silicone. 

Tips for replacing bathroom silicone

  • Ensure old silicone is completely removed before applying new. Silicone removal products will help this but white spirit can also be used. 
  • Removing old silicone is the most time consuming aspect of the job but it’s important to get it right.
  • Dry the area fully before applying new silicone
  • Use a good quality bathroom silicone with a high level of mould resistance. We’re fans of Dow Corning silicones. They are more expensive but definitely worth the couple of extra pounds for a tube. 
  • Leave the silicone to dry (cure) for 24 hours before letting it get wet from the shower.
  • And as we say above, try to keep the area well ventilated when bathing or showering.

If you are replacing bath sealant or shower sealant with new silicone then there are a few things that are worth keeping in mind.

Replacing silicone in your bathroom (or kitchen) is certainly the type of job most people could do themselves if they have the right tools and a little time and patience but we are here to help if you would rather have a handyman carry out the work for you.
