After having numerous problems with our fitted kitchen due mainly to the "professional" installer, 12 months later we have discovered two slow leaks from the pipework under the sink. We had a problem with our washing machine, which meant pulling it out, only to find thick black mould on the walls and pipes and a wet floor and tiles. My husband has had to cut the unit around the pipes to tighten up the connections and stop the leak, and hopefully it will now be ok. Yet again the installer has proved us right-he was highly unprofessional and should not be allowed anywhere near people's new units and appliances! Do not let a Wickes installer near your new kitchen if you want a good job doing. We wish we had arranged a fitter ourselves abd would never use Wickes again.
