I'm interested in this too!
I've just had someone board up one part of my loft (its actually the side of a dormer) - can recommend Radek of London Capital Painters as they also do carpentry. His number is 07912891266. He even insulated it for me for free!
hi Neil and others
Did Radek do that work for you and did it go well? I've just asked him round to give a quote on Wednesday for the same type of job
We had Radek do a chunk of work in our house a few months back - he did a great job and was very trustworthy.
