Keane's fitted secondary glazing for me in a city centre apartment building that already had good double glazing. The problem was city traffic and building noise. The advice on what needed to be done was excellent, and the the delivery and excution of the job could not be faulted. All the interactions were courteous, professional, pleasant and, most important, reliable. Things happened when they were promissed and so on. Installation took only about an hour per window and everything was cleaned up and tidied after the job was finished. The job/ service was a bit more expensive than I anticipated before seeking a quote. However, it was delivered within budget, and is well worth it. It has been very effective in eliminating the noises I was concerned about. Jim M. read more
