Great Service , great product

A bit wary using a company that wasn't recommended as I do wìth most suppliers . Bit nervous after placing order as text comfirm came from a US number (just the type of web order system they use) and I messed up my email address ,which compounded the problem. But I needn't have worried . UK based company , nice helpful chap answered phone promptly ,put my mind at ease . Window boards arrived in good time via courier, robustly packed in perfect condition. Will definitely use these guys again .

Completely understandable about your hesitancy Tony, but glad you trusted us for your order! You're correct regarding the ordering system as our software isn't UK based, though thank you for highlighting the number origin as I may look at a way aroud this to save and worry or confusion with future orders.

I'm really glad I was able to help with your order and it looks great in situ. If and when you need anything else you know where we are.

Another quality sill from Essential Woodwork

I am currently renovating a house in the Scottish Borders, every sill in the property to date has been supplied by Essential Woodwork. There are another two in the system right now being prepared ! The quality is superb and dimensionally exact as to your order, I’ve been on with this house for 4 years and the previously fitted sills are perfect not one bit of twisting or movement, I finish them with Osmo Oil and that’s it; if you want quality wood products then use Essential Woodwork as they are outstanding you won’t be disappointed.

Thank you for such a great review Kevin, it's really appreciated! Fantastic to know that you're pleased with your oak window boards, and they look great in your photos. Thank you for taking the time to upload those for us also; it's really good to actually see our sills in situ.

Your other window boards have actually just been collected today and should be with you tomorrow! I hope that you're as happy with them as you are with the others :)

excellent piece of wood

very pleased good delivery and wood exactly as ordered fits and looks perfect

I’m glad that you’re pleased with the oak John. You know where I am should you need anything else.

Luke (Swindon)
Great Quality yet again :)

I rarely write reviews, and when I do its usually to warn potential customers of negative issues to avoid. I make an exception to Essential Woodwork. Ordering Oak online without seeing the piece is a very scary proposition. I have had 2 orders from them now and I and exceptionally happy with both of them.

I am positive I will be making orders in the future.

Thank you Luke :)

It’s great to have you return for further orders and really glad we could provide what you needed, and importantly are happy with the oak boards. Thanks for taking the time to provide a review, we really appreciate it.
