Key Features

We pride ourselves on machining and supplying some of the best oak window sills that money can buy. Here are a few of the features that make your buying decision a whole lot easier.

We'll do the hard work

We go the extra mile to make sure that your oak window board is not only machined well, but sanded ready for you (or us) to wax, oil or varnish.

Trimming option

Don't want to trim the oak sill yourself? No problem, we offer a free 'trimming' option so that you can order the exact size sill you need.

Kiln dried solid oak

We only use the very best kiln dried solid Oak, which demonstrates beautiful grain detail, colour, and is made to last.

No costly waste

No need to order overly long or wide oak window boards. Our length options increase by 0.3m and width by 25mm so you can choose the most suitable size.


We understand you might have a few questions you'd like answering before ordering. Here we list a few of the most common one's, though you're welcome to contact us should you have something else to ask.

Would you trim the sills for me?

Yes we can. Use the size options to select the next size up to the dimensions you need and then enter the sizes you’d like the window boards trimmed to in the 'Trimmed to size' section of the ordering form above.

I guess the sills are heavy, is delivery expensive?

Solid oak is quite heavy but we’ve made it easy to understand delivery costs by providing all of our products with free delivery. The price you see on the product page is the exact price you’ll pay, no hidden costs added during the checkout.

Are the window sills smooth?

Yes, not only do we machine your window sill precisely, we also sand them before delivery so that you receive a high quality sill that’s smooth and free of any blemishes.
