Black painted oak wood flooring downstairs was sanded clean. Primed and varnished with clear varnish (two coats). Upstairs, all floorboards were sanded and treated similarly. There was a one day over-run, but it was well worth it. The work was superbly done. The floors all look stunning. House was left spotlessly clean. Price paid was price quoted, even though we asked for a (relatively small) couple of extra areas to be treated. Very pleased indeed.
