trust me to do. However, it's started lifting very slightly as if water
has got into the chipboard worktop.

If I get him back in, is there anything he can do?

Is there anything I should/could do?

Have I been doing something wrong - shouldn't the join withstand water?


The big question is what did he do to waterproof it.

If it's properly sealed it should withstand water. I normally spread
some PVA wood glue acorss the surfaces. Any minor crevices can be
filled with a worktop repair filler to stop water sitting.
Dependent on the damage and pattern of the worktop you can try and
repair the damaged laminate with a filler.
