Howdens kitchen fitted 5 years ago by local builder.
Just noticed worktop has water damage. It's 15cm from the sink.
I feel like this shouldn't have happened but is it the worktop or the fitter at fault (he cocked loads up).
I'm worried it's going to be expensive to fix as the tiles are sat on the worktop.
Should I suck it up and pay for a new one, or try the builder or Howdens?
Advice appreciated
