Great custom made window sill

Very helpful service, quick dispatch, excellently wrapped and a beautiful finish.

I’m glad you’re pleased with the custom window board Roland and great to hear that you found our service helpful. Thanks for the feedback.

Perfect in every sense

Quality, price, delivery, customer service all spot on.
The website navigation was well thought out and the choices impressive.
I tried getting what I wanted, oak plank with routed edge for window cill at a local reputable major timber merchant but they could not offer me the dimensions I wanted. Essential Woodwork came up with just what I needed at 40% cheaper delivered including waxing.
I'll be recommending you to a builder friend of mine.

Thank you for the great review Paul. I’m really pleased that you were happy with our service and were able to buy the exact window board you needed at a price you were happy with. We always appreciate a personal recommendation and look forward to your builder friend hopefully getting in touch in the near future.

Thanks for the great review Bob. We actually have quite a few customers using our window boards as door sills and glad that you’re happy with yours. Get in touch should you need anything else, we’d be happy to help.
