I was going to give 5 stars but I can’t.....they “done” the job at my house 1.5 months ago however it’s still not completed. Still awaiting for my spy hole, door number, security lock and safety chain to be fitted.....they've given a date - 4 days after the installation but never turned up. When I’ve made a complaint -various problems have arisen with the windows/doors in the meantime anyway - I’ve got an another date but have been cancelled again.....have a third date, we’ll see what’s going to happen. I can understand, their are being busy and maybe working less staff due to recent circumstances but we can’t blame Covid 19 for everything. Need more better organization, seems very unprofessional. The only good thing was the professionalism of the two engineers who fitted the doors and windows. They were excellent and worked in harmony with each other. I would recommend self-adhesive house number/ knocker to use and not drill and damage the expensive guardian or even upvc doors. Also would be great to offer improved safety chain - again, this would only serve to protect the door against drill damages. Overall, I’m being very disappointed.....
