I was invited to quote for the external redecoration of oak windows on a large converted coach house in rural Lincolnshire. All the oak windows had been handmade for the property during the refurbishment.
Unfortunately for me, at some point since, the windows had been painted in an unknown opaque stain. This totally concealed the grain and spoilt the natural beauty of the oak. Also the stain had failed in several places, allowing water to penetrate, which in turn discolours the oak, turning it black. I soon realised that the windows would have to be stripped back to bear wood and redecorated from scratch.
On a property of this size, a mammoth task !
