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.

All the hard work done

We make sure that every oak window board that we send out is machined perfectly and sanded, ready to fit as soon as it arrives.

No excessive waste

We hate to waste beautiful natural Oak, and we wouldn't want you paying for it either. Our oak window boards are available in 300mm increments.

Very best solid oak

Every oak window board we produce uses only the best solid Oak, with fantastic grain detail and colour, along with durability that will last.

We'll trim to size

We understand that you might want your Oak window board made to the exact size they need, rather than trimming yourself. We'll trim at no cost.


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.

Can my window sills be cut to size?

Yes they can. Choose the next size up to the dimensions you need and then enter the sizes you’d like the window sills trimmed to in the appropriate section of the ordering options box.

How much will it cost to get my sills delivered?

We like to keep things simple which is why all of our products are provided with free delivery. The price you see when selecting the options on most of our items is the exact price you pay.

Can I choose to have my window sills sanded?

No need; all of our window sills are sanded after machining to ensure a perfect finish.

Beautifully finished!

It arrived extremely well packaged and the finish is just beautiful. I had it custom cut and it fits perfectly. Would highly recommend this company.

Your window board looks fantastic! Great to see the item fitted in all its glory! The light brown wax looks superb, and I'm glad to hear that it fitted easily after having your window board trimmed to size :)
