    Leak under kitchen sink

    Kitchen Fitters

    I have a leak underneath my kitchen sink which seems to be due to the fitting (I.e. I think the sealant has worn away around the sink and it's a wooden worktop). It's 6 years since it was fitted. Is there a specific type of sealant I need or does the sink need refitting? I don't want the sealant to show and the gap isn't very big!

    "Any kitchen silicon sealant would do the job. Just check that the leak isn’t coming from taps or waste. Make sure before sealing that you remove as much of the old sealant as possible and that everything is dry!
    Many thanks"

    "If it's a stainless steel sink remove and replace the worktop will need to dry out and have a quick sand before reinstalling. If it's a ceramic sink just remove existing silicone and re silicone around the sink"

    "Remove old silicone with silicone remover chemical available at Screwfix. Apply new clear silicone just a neat thin bead I would recommend Dow Corning 785 with anti bacteria and mildew ideal for a kitchen application. Good luck 🤞

    "Clean the area and use a sanitary grade clear sealant. Clear sealant dies not show up much as white. Make the opening on the sealant small as well so it's not excessive when applied"

    Normally kitchen sinks have a foam gasket that sticks underneath and is hidden the inside of worktop where cut should be sealed too with a sealant to prevent rotting you may want to check they did this incase it’s got wet and damaged worktop
    Also a tiny bead of silicone can be applied around outside edge of worktop that will hardly be visable if you use a coloured silicone that is a match to sink and work top
    If you do not wish to remove the sink to re seal that is"

    You can purchase white or even clear silicone from any major DIY retailer.
    I hope it helps."

    "You can seal it back up but best to get it all replaced. That way another problem will not occur."
