Ordered 2 oak window sills from Essential Woodwork excellent quality and delivered on time will highly recommend and use again.
I've ordered a couple of times now and received the window sills and shelves in perfect condition, I would highly recommend Essential Woodwork Ltd to anyone who needs anything oak. Thank you Justin for putting up with me on the phone when I had lost my voice!
Nice piece of oak, well packaged and reasonable price. Postage is free which is a real bonus. Unfortunately delivery times are glacial. Altogether a good service, would use again.
Best value oak boards around. Quality graded oak. Perfectly finished - hardly any finishing required - just a light 120 grit sand over. Perfectly machined straight and true. No imperfections. No knots or splits. Nice tight grain. Absolutely superb product and service. Perfectly wrapped for safe delivery.
Arrived as expected and beautiful quality
Love my new window board after decorating my hallway. I will be replacing them all eventually! Just bought another one! 4* due to longer lead times than other places.
