Right it is a 2 beds house, ground floor and first floor. At the top I have got a roof space which I would like to convert it. I was wondering I much it will cost me to strengthening a floor joists on the loft by a builder. I would like to make things right and properly. However, I am good at DIY and other things such plumbing, put the boards down, insulating, making partition walls, I can do myself without problems. I believe electricity I can do it but I cannot connect them as I need a professional electrician to do that, but doing the main job, like putting through wires, I can do it, am I right?
I just need to find out by a professional, how much does it cost to strengthening joists, also fit a small dormer window (already made, just need to add on the roof) and two velux window and a winding staircase. If someone is so kind to give us an idea so we know when we get some quotes we know we are on the right track.
Thank you.
