Did you know that at no additional cost, we'll trim your sill to the exact length and width that you need, saving you time and money.

The length you need.

No more costly wood waste! We don’t want to see you having to spend money on buying excessively long window sills, just to then have to cut the sill down to the correct length to fit your window reveal. Not only is it a waste of good oak, it's a waste of your money too. Instead, we provide the option to buy square window sills in increments of 0.3m (300mm), starting at 0.6m up to 2.4m in length.

The width you want.

Whether it’s a narrow or wide square edged window board that you’re after, we’ve got you covered. With pre-set options of 200mm, 225mm, 250mm, 275mm and 300mm we can meet the requirements of nearly everyone. But we don’t stop there! We can even handle narrower and wider window sills, all machined in one solid piece of oak if you’re after something a little bit different.

The thickness to suit.

Our square window sills can be machined to any thickness to meet your requirements. We have 3 pre-set options to choose from; 20mm, 25mm and 30mm, although we’re more than happy to cater to bespoke thicknesses if you require them. In fact, with your cut-to-size service it’s not only the thickness that you can have customised but also the length and width combinations too.
