Absolutely shocking service. Came out to fit a new front door and 3 dormer windows. One of the windows had a broken hinge when they installed it - "Someone will be out next week to fix it" A second dormer broke the following day and wouldn't close. As for the front door, without asking they hacked off part of our skirting board and cut off part of the new doors plastic frame. They didn't measure it but filled in the bit they cut too short with a massive blob of silicone. Then they siliconed the bottom of the door frame to our door mat! The engineer came out the following week to fix the 3 problems, but was only allocated a 30min time slot. He fixed one window and then left and said he would be back in a MONTH to do the other two issues. The one he "fixed" broke again the following day. We then got a call to say the appointment to fix them in a month has been postponed a further week. We'll see if they ever come back and actually put it right. Really expected better from a big national company.
