Window boards

Needed some pieces of oak cut to size for 2 cast iron radiators to sit on. Ordered these window boards as there was no additional charges for been cut to size. Very impressed with the product and service and I will definitely use again. Thanks

Oak window board

Excellent product. Bought as window board but I'll actually be cutting in half and joining lengthways to make an oak top for a unit. The quality looks great so should have no trouble making a neat join. Price was good too.

Thank you David. Great to hear and I'm pleased that the Oak is what you were hoping for. You know where we are should you ever need anything else.
