Julian Whittaker (Fulham)
Excellent Customer Service

This order was a replacement oak window sill for one that was previously sent which had a hairline crack, the seller replaced the original stating he wanted the customer to have a good experience, i cannot fault this man genuine and thoroughly recommended without hesitation

Thank you for the kind Julian, and my apologies for the initial issue with your original board. It's very rare to have any problems as we try to double check anything we send before packaging, but unfortunately this slipped through and wouldn't expect you to put up with something that was less than perfect.

The photo of the window board fitted looks fantastic, thank you for adding that to your review. It's great to see as well as read customer feedback, and you know where we are should you ever need anything else.


Friendly team who are helpful when resolving queries and great looking product
