The window sill is a beautiful piece of wood and finishes off our new build kitchen window perfectly. Well finished, well packed for delivery and a good looking piece.
I am building a home bar and wanted a decent piece of oak as the counter, most visible and needs to be solid. I scoured the internet looking for a decent price and found this site. Exactly what I was after and although should be a window sill, still perfect for sitting beer on I’m sure. Wood came really well packed, flawless and is a cracking piece. Highly recommended. Not built the bar as this is the only wood that’s come yet, wickes had a month lead time on the struts. Oh well.
Very pleased with purchase, delivered well packaged for protection, good communication, definitely use again and would have no hesitation recommending.
Was very pleased with both service and product many thanks
Great pieces of wood at a great price. They also gave me some great helpful advice. Thankyou
