We had our windows and doors installed last September and we have had to have installers and surveyors come out on numerous occasions to re-do the shoddy workmanship. They have no consideration for the interior or exterior. We have had our walls damaged, taken several days off work so they could come in and they left shattered glass from one of our old windows all over our lawn and rubbish in our back garden. When we mowed out lawn, it got damaged from the broken glass we couldn't see and they refused to send some one out to clear up the mess or compensate us for the mower. Great customer service guys, thanks for the added stress.
