Elegantly handcrafted solid oak window sills. Made from thick kiln-dried French oak and joined by our expert team.
We are able to cut bespoke oak window sills to the mm to fit any size alcove.
We join full-length solid oak boards to make the length of the window sill, this creates a more natural and beautiful finish.
Important - Please note the following before purchasing;
As our oak sills are a natural product, each piece may be different in appearance and vary slightly in colour.
If ordering widths generally over 150mm+ these will be made up of joined boards.
Make sure that the weight is properly supported and the boards are fixed correctly close to the delivery date to ensure that they do not bend or twist.
