Good service

Found this company after a bit of digging and really happy I did. The wooden window board I ordered came very well wrapped and was of good quality. The grain looks great and now its fitted it really sets off our new windows. Much better than plastic or oak veneer MDF. Why not take a look on the web site yourself?

Great to hear that you decided to buy from us, and that we lived up to expectations Steve. It's always good to know when we're doing things right! Let me know should you ever need anything else.
