Very knowledgable salesmen who advised us on style of window, how it should open to cater for the wind on our block right to what size of window would look the best from their experience. We chose the imported doors and windows and have been really impressed with the quality. Special mention to the installers who removed the old windows and put new ones in during the wet weather in June, with no mess at all. Especially as they had to chip out the tiled windowsill. thanks guys!
