I genuinely can't warm you strongly enough not to use this company. I had Windows installed in June. You will have scaffolding for any Windows above ground floor, and they will be there for about a week before the installation, and then for around about two to three weeks afterwards. The scaffolders won't have been told what the job involves, so will have to come back twice, and argue with the fitters as it has be installed incorrectly. This means on the day of installation, the fitters won't start until the scaffolders return. The fitters meanwhile, will leave a mess in every room they go to. There will be expanding foam on walls, bedsheets and the carpet. You will have to repaint one room due to handprints in silicone on the walls, and replace a windowsill in another. All of this will not become apparent straight away as you will be too focused on the fact that the locks on several of the windows are incorrectly positioned and won't lock. This will handily focus you on the fact you now, thanks to safestyle, have a handy ladder to a now insecure window or three for easy burglar access. Just to ensure your home is now fully open to the elements, most of the trickle vents will be poorly fitted and stuck open. You have to hand it to safestyle, as for the sake of completeness, they will also ensure that one of your fire escape windows will not open without shoulder barging the lock, to ensure you really mean it when you need the window open. Fortunately, Safestyle will send an engineer to fix this minor failings. He will arrive pretty much at random and with no parts to fix anything. Expect them to disassemble one of the locks, making another window insecure, state its not their problem, it will have to be rebooked and leave. Never fear, Safestyle will leap to a speedy two month response time, and then ignore any and all contact as you try to tell them the day they have randomly assigned may not be suitable. Even asking for an afternoon appointment time is far too cheeky, as their engineer will eloquently point out when you say you can make 11am at a stretch. The excitement and adventure of attempting to hold Safestyle to their promised standard is truly something the courts alone may be able to quell. Honestly, I had used safestyle before and they were fine, but on the basis of this occasion, you will be better off with any other supplier. I do not know what has changed, but I will avoid them in the future and will tell any and all they would be better off never engaging with them.
