Solid kiln dried oak
No veneers or MDF here! We only use high quality kiln dried solid oak for our window boards, offering a beautiful finish and durable sill.
Trim to size option
If you want to fit your oak window board as soon as it arrives, we can trim to the exact length and width that you tell us to when ordering.
All of the hard work done
In addition to optionally trimming your window boards to size, we'll machine and sand every piece to ensure an excellent overall finish.
No costly wood waste
Using our ordering options, you're able to choose a window board that most suits your size requirements, from 0.3m length and 25mm width increments.
Do these sills need sanding?
We do that for you. After machining, we sand all of our window boards to ensure a perfect finish.
Would you trim the sills to size for me?
Yes. Simply select the next size option up to what you need and in the 'Trimmed to size' section of the ordering form add your dimensions.
What does delivery cost?
All of the prices you see on our website include free delivery. We like to make it easy so there aren't any unexpected costs sprung on you during checkout.
Best value oak boards around. Quality graded oak. Perfectly finished - hardly any finishing required - just a light 120 grit sand over. Perfectly machined straight and true. No imperfections. No knots or splits. Nice tight grain. Absolutely superb product and service. Perfectly wrapped for safe delivery.
Arrived as expected and beautiful quality
Love my new window board after decorating my hallway. I will be replacing them all eventually! Just bought another one! 4* due to longer lead times than other places.
Very competitive price for a perfect oak window sill, delivered on time, in a comprehensive protective wrapping. Great service throughout.
This is the second sill I've ordered from Essential Woodwork, extremely satisfied.
