Anyone know of a company who will give me an estimate for work to sash windows? Need to repair from inside as it's a 3rd floor flat and too high up for a reasonable price if they had to put up scaffolding. Problem is I'm still in the process of buying the flat and the window companies I have contacted appear to think I only want an estimate to beat down the price. I might ask for a price reduction if it's really expensive, but my main aim is to book to get the job done as soon as possible after I exchange contracts and get it repaired and serviced, if possible before I move in (owner has already moved away and it's empty). Any sash window companies you can recommend?
