We called Phil after we found about Fog Free Windows from a local ad booklet. We were replacing 35 panels - windows, door glasses, sidelites. He came the next day to take measurements, and provided his quote right away. His prices were by far the best of everybody else (at least 25%) who came to look. Before him, others were trying to convince us that glass panels can't be replaced, that we need to replace the entire window.
It is refresher to find out that there are still honest tradesmen.
I know where to go if I have anything to do with glass around house.
