Hoping somebody can offer some advice here. I've had a kitchen professionally installed and am currently in dispute with the company over the quality of workmanship on the worktop fitting. I have a large breakfast bar section coming off a main sink section at right angles. The sections are not 100% perpendicular - although the installation manager is insisitng they have to be as the jig won't cut anything but..... I estimate that the brekafast bar is about 13 mm out of alignment at the extremity (1.9m length). Can anyone tell me if that's an acceptable or normal tolerance...... A small lip also appeared after about 4 weeks which the fitter has managed to re-adjust but I've been left with what I would describe as a minor warp/bubble. It's not siginficant, but definitely noticeable in certain light conditions and defintiely noticeable to touch. Any suggestions/advice gratefully received.
