Which? Local Review
I Just felt i had to write a review of this decorating company. From the very start, the service and the work was impecable. very good value for money and many extras were thrown in for free. which is always a good thing. They offer many extras with the service including a free touch up service. The company was recommended to me by a friend which is always the best way.
