Window sill

I am so pleased with this purchase. I wanted a finished wooden sill that I could just pop in and that is exactly what I got. The quality is exceptional, really heavy solid wood with bullnose edges and a waxed finish cut perfectly to size. I shall be using Essential Woodwork again, thank you so much.

Thanks for the great review Amanda. It's great to hear when customers are happy with their purchase :) Let me know should you ever need anything else.

Excellent delivery, very good packaging and good quality product. Very happy.

Thank you John. Always great to hear from satisfied customers and I'm glad the window board lived up to expectations.

Bullnose oak window sill

I wanted 2 x 1 metre lengths, you only sell it in 1.2 metre lengths so 0.4 metres was wasted. Otherwise the product was very good.

Hi Keith, thanks for the feedback. We have a 'trimmed to size' option for customers that want their window boards cut to a specific size, and price the increments (currently 0.3m) closely, so that customers aren't paying a huge price difference if for example they chose a 1.8m board to a 2.1m board. I'm glad that you are happy with the actual product though, and maybe get in touch with us if you need anything else at a specific size and I'll work out our best price on the dimensions rather than our standard sizes :)
