Nice product sensible price
Thanks Julian, we aim to please!
We were very happy with our oak window sills which were cut to size, beautifully finished, well packaged and delivered with a great courier. We spoke to Essential Woodwork as well as ordering online and the whole process was very friendly and easy.
That’s great, thanks Lee. Really good to know that you’re pleased with your oak window boards and we were able to help. You know where we are should you ever need anything else.
Quality piece. Had cut to size and it fits perfectly. Excellent packaging.
Would use this company again.
Thank you Cheryl. Always good to know when our cut to size window boards fit like they should! Thanks for the review.
Great service when quick delivery was requested
Thank you Lisa, I’m glad we could help :)
The wood is amazing quality and was cut to perfect size. We oiled/waxed them ourselves and the colour was amazing. Justin has amazing communication and chased up orders that were delayed without being prompted (greatly appreciated) - wait time for dispatch is my only advice on improvement, but they are 100% worth the wait! Highly recommend (ordered 6 in total)
Hi Charlie. Great to hear that you're pleased with the sills and thanks for taking the time to write a review. Dispatch time is something we have worked on recently and have introduced a quicker dispatch for those that choose it during checkout. Being custom made, often to exact customer dimensions, makes it more time consuming but we do try and get the turnaround as quick as possible. Let me know should you ever need anything else :)
First class product and service, I will be buying more.
Excelllent! We always like to see repeat customers and so glad that you're happy with your window boards :)
