Ki-Fix did the work for my 2 bath condo, but it was a rough journey to completion. Ki-Fix was selected by my condo corporation to complete all the ki-tec replacements.
In May, I contacted Ki-Fix for a quote, and it took a month for a quote to be received and signed on by both parties. I gave a deposit on July 3, and proceeded to start to chase Bob to actually come and do the work. Bob agreed to two separate dates, and no-showed both times! The first no-show came with an apology and explanation, but the second got no response at all.
My building concierge took pity on me, and gave me the number of the project manager, Susan - the work began on Aug 9th and was completed on Aug 16th. The entirety of this time I was staying at a friend's place.
Also, it's relatively small compared to everything else, but I found that the cleaning service provided wasn't particularly great or thorough.
