mmm nice wallpaper on the right, transformed to hallway below right. A bit of an improvement I hope you agree.
In this case it was more than just stripping wallpaper, cleaning walls, undercoats & topcoats but great transformations can be made with a lot less effort. Just cleaning down the walls and putting on a new top coat of the same colour can freshen up a room and cost a lot less than more major works.
External woodwork must be regularly maintained if it isn't to rot. Rubbing down woodwork and giving it several protective coats will prevent a much more expensive bill in the long term & keep the outside of your house looking as good as the inside.
