Any internal timberwork can be finished and treated in the same way as any other internal timberwork in your home. Where window boards (internal sill boards) have been replaced they can either be stained or painted, depending on your choice from room to room. Doors, for example, would regularly be finished internally with architraves and timber liners. Most people then paint these to match skirting boards and other architraves, but the choice is yours. It should be remembered that all such decoration is not part of the contract and is the responsibility of each individual homeowner.

To keep your Global windows and doors looking great, clean the PVC or Composite / Glass Reinforced Plastic (GRP) sections once a month or so with warm water and a squirt of washing up liquid, using a non-abrasive sponge or cloth. Glass can be cleaned in the same way, but we recommend drying the surface afterwards with an old newspaper to help remove streaks. Proprietary glass cleaning products may also be used, but please ensure the frames are washed down as described above to ensure no residues are left. Once or twice a year, lightly lubricate the handles and other hardware items using a product such as WD40. Open your windows and doors at least once a month to keep them operating at their best.
