I just had my old wooden door and door frame replaced with a new composite door. I have a very old stone built house, and I was surprised by the size of the gaps between the door frame and brickwork. The whole reason I’m getting new windows and doors is because I would like the house to be warmer and have better energy efficiency. I asked the guy installing the door if he was going to use any installation, and he said that that wouldn’t be necessary. He is coming back on Monday to finish the job by just covering the gap. Is that going to be okay?
Any advice would be greatly appreciated.
