This company charged us £17, 500 several years ago to double glaze and supply patio doors for the entire house. We have had consistent problems which they have persistently either refused to come out to look at or successfully repair/ replace. We have damp interior walls from windows, sticking patio doors and almost the enite supply of window handles are cracked or broken. They ignore phone calls and letters and have done an appalling job. We are honest people who paid their bill immediately and have been treated appallingly.
