Our oak window boards won't be beaten.

It's our belief that our solid oak window boards are second to none. High quality craftmanship, unbeatable price and first-class service.

Choosing a window sill length

Our standard interior window sill lengths start at 0.6m (600mm) and increase in increments of 0.3m to save you paying costly wood waste. Our maximum length option currently stands at 2.4m, though custom orders are welcome if you need something that little bit different.

Wide variety of width options

All of our wooden window sills are available in several widths, including our pre-set options of 200mm, 225mm, 250mm, 275mm and 300mm, though as with our length options we can cater to bespoke size requirements, including wider and narrower window board widths.

Thicknesses to suit any requirement

The days are gone when the standard 22mm thick wood window sill was the only option, and we recognise that by offering all of our styles of internal window sills in 3 different thicknesses. Window sill replacement has never been so easy and as convenient as when buying from us.

Window sill sizes

Free 'cut to size' service on all oak window boards!

We can machine and cut your solid oak sill to the exact size you need. The perfect sill to fit precisely to your measurements, as soon as it arrives.

Need to know more?

Our wide range of length, width and thickness combinations makes us the leader in high quality solid oak window boards. Even with our extensive range of window sill profiles, we understand that not all window reveals are the same, meaning the exact width and length combinations that you need might not necessarily be as per our ordering options. Unlike our competitors we don’t like to leave you hanging, which is why we offer a free cut-to-size service no matter which style and size of hardwood window sill you would like.

Ordering is simple. Select the length and width of oak window board the next up to the size you need and add a note during checkout of the size you need the sills trimming to. It’s as easy as that, you’ll receive your newly machined wooden window sill board at the size you asked for within days.

Our bullnose, chamfer, and round-edge oak window boards can also be profiled on the ends (the returns), so that not only do we machine your chosen profile to the front leading edge of your sill, but also the left and right hand edges if you so choose. We have this option readily available when choosing any of these window board profiles.
