Read moreGreat teams attended a job over 2 days to install fly screens on 1st floor apartment windows using a scissor lift. Very fiddly job with some complications including access from a busy, narrow laneway and hot weather. They were good humoured and cared about doing an excellent job. Which they did. Thanks, so much guys. Would highly recommend Glenco.
