Unfortunately not great service from the Window Hub. Delays in quoting, constantly chasing for admin reasons and had to chase my own installation date. Guy on the phone told me it could be done in 1 day so I arranged 1 day at home with work, installers left early because they had to get back to watch the football and came back the next day for a couple of hours. When I expressed my frustration with the admin guy on the phone he just said 'sorry about that' and moved on to asking me to pay my invoice in full, didnt seem to care at all. In addition to that, we've since had to reseal one of the windows due to a hole and an ants getting in. Not impressed, will not be using them again.
