Kitchen Fitting

Worktop has sunk slightly on all 4 corners of the sink.

Anonymous user 15/03/2024 - 2.52 PM

Worktop and sink have been installed for 12 months.(Chipboard laminate). Would the worktop sink inbetween corner to corner of the sink/drainer front and back (back of the sink to the window) and (front of the sink to the edge of the benchtop, even though the sink had a seal applied and the cutout for the sink has been sealed with a carpenters PVA (waterproof) which stops any penetration from any water that may get through the sink seal. When checking underneath the sink the cutout around the sink, the chipboard was still firm... But the sink corners had kinked up slightly. Why would this happen? Comments would be interested to see. Hi thanks for your feedback. The sink was completely sealed when installed and a pva was applied to the cut edge of the worktop, so no swelling of the worktop. Heights of the cabinets have been set to their standard height. Sink brackets were not overly tight. Would it be purely down to weight on/in the sink. A glass splash back was installed a couple of weeks later around the worktop, behind the sink the splashback is between the worktop and window sill. Theres not much worktop at the rear of the sink.

Are you a tradesperson and able to answer this question?

Hi Jase Sounds like an installation issue, maybe its not so much that the work top has dropped but rather the corners of the sink have risen due to excessive pressure of the fixings holding it down that are causing the sink to bend up in the corners where there is no fixings. The other thing it could be is that the unit underneath the sink is pressing hard up onto the worktop and due to limited worktop in that area due to the sink cut out its weaker than everywhere else. If that is the case then you could try releasing the pressure from the feet. Hope this helps. Frank

Hi jase definitely inastallation issue, as frank said there’s probably unwanted pressure being applied along with the weight of a full sink/water forcing down it’s starting to lift the corners. Hope you get this resolved Nathan

Hi from what you have said the fitter hasn't applied sealent in the corner properly which has created a spot which water can get to, it will get anywhere and once its lifted and swollen it needs replacing before it spreads, in my opinion that is what's happened

Hi If the units under the sink have had there cross braces cut out too much this will cause it to sag in the middle as this weakens the unit structure, also there sound be about 50-60mm of worktop top left at the front and the back, we usually cut the sinks in tight and install the sink into the worktop before the top goes into place to ensure all the sink brackets are fitted correctly and tight.
