  • Hi , I’ve been working in the Glazing / building industry continuously since leaving school in 1980 and initially being an apprentice carpenter ( basic and advanced city and guilds ) . Followed up with 4 years on site carpentry work before moving into the upvc window world in the mid-late 80’s . Moving naturally into fitting conservatories in the early 90’s when they were booming for around a solid 8 years before moving into installation management for 4 years . Having picked up al the relevant skills over the years I then went out building conservatories and small extensions working for myself which had continued to this day .
