Hi all,Looking for some advice on fitting an external garage side door.The gap for where the door can go is too wide for an external door frame kit - not sure how best to fill those gaps? It’s a concrete garage which is in pretty poor shape, the door is as much a cosmetic wish rather than a security wish.I’m UK based and lots of DIY stores sell external door frames, but the size will obviously mean I need to add something in to fill the gap.Any advice/tips on how to approach? via /r/DIY http://bit.ly/2PQG3ew
