Can anyone recommend a company in North London for sash window refurbs? A few rotten bits, some ropes/pulleys that need replacing, etc
Also, how is it normally done, are they renovated in situ or taken out and redone at a workshop or whatever? If taken out is it done from the inside, from the outside with a ladder, with scaffolding? (I don't have access to the back of the house so need to arrange with downstairs so the easier the better).
What are the options for glazing, some have stained glass which I'd obviously like to keep. Can some thin form of double glazing go in or is that too thick? Cheers
