For interior panes we damp-dress one cloth with a low-residue solution and finish with a dry, smooth-weave cloth in a single direction. No aerosol mist, no overspray onto curtains, joinery or radiators below the sill.
If a finished window shows a streak under daylight within seven days of the visit, send a photo and we'll redress it at no charge. Window finish work is the easiest of all our lines to keep this promise on.
