I highly recommend Bohdan and Leo (BML). I contacted quite a few other Ikea cabinet installation specialists and Bohdan was the most responsive. In fact I called Bohdan from Ikea a few times and he was happy to advise me even though it was well past 5 PM.
It was clear that Bohdan and Leo had a lot of experience with Ikea and they offered great advice. For example, I bought cup pulls and handles from Restoration Hardware and Bohdan warned me that the screws that it came with would rip right through the MDF Adel doors during normal usage. Sure enough, I searched Internet forums and many people were having this problem and as a result they had ruined their cabinet doors. Thanks to Bohdan's experience and insight we avoided this problem by getting some nuts and bolts from the local hardware store.
Again I can't recommend these guys enough. They knew what they were doing, the result looks perfect, the job was done quickly and the price was right.
