goin g to get someone in to give us quotes soon, but need an idea wether it is even worth bothering.
terrace house, only windows on 2 stories so no scaffolding needed. 6 windows and 2 doors. want a much lighter colour than it is at present, will this make much difference.
also was thinking sage green and cream but also wonmdering about red and cream, any opinions? it is currently brown and cream, all the other houses on the road are blak and white.
