Ed installed several Milgard windows; as well, doors in my resident. I live very close to railroad tracks and specifically requested and relied on ELMs expertise to install windows which provide the best defense against train noise. This was the emphasis and objective to which windows I relied on and trusted his selection! Not only did I have to replace a large bedroom window within 60 days of his install; (with a quiet line series at a tremendous cost); but was informed that the several other windows Ed installed were done incorrectly! When confronting Ed of the situation, he stated he was not aware of the quiet line! Unfortunately, they have been out for years and he represents the Milgard window line. I would not use ELM in the future, not reputable and a costly and VERY BAD experience!
