Hello, We're looking for a builder who specialises in exterior repairs to older concrete window sills. We've got a Victorian upstairs flat and a few of ours are heavily eroded/blown and need some repair and restoration - as do the ones belonging to the flat below us. Has anyone had work like this done and if so can they recommend someone local who's familiar with this kind of thing? And it'd also be good to hear from anyone who does this kind of work themselves too! Thanks very much, Simon
