Hello, hoping someone can help! We've just had a new garden door fitted (where there wasn't one before). There is now a big gap (2"+) between the internal wall of the house and the door. How do I bridge this gap so that it is secure (doesn't move around / squeak every time you tread on it) and looks OK when connected to the internal flooring (the black tiles)?
There is also a small height difference (approx 2cm) between the tiles and internal wall / threshold that can't be seen very well on this pic.
Any advice would be greatly appreciated!
