Used JK Crown Moulding for our new house .Alexandr suggested to install foam crown moulding and we agreed. The installation was done very good with good quality and quickly. When I started painting it ( the moulding was primed and we were told that primer was not required) with Benjamin Moore water based paint for mouldings and ceilings one of the room cracked almost everywhere. I had to use oil based primer (two coats ) for the other rooms and it saved the moulding from cracking. Tried to contact Alexander several times.... Useless. Ignored phone calls and messages for 2 ,5 months. And only after I posted this review and forwarded a copy to Alexandr he finally replied saying that he doesn't make the moulding ,he only installs it. That's very upsetting that professionals don't stand behind their jobs. I will never use this company again and advise not to use them.
