"2 x Internal window sill replacement. Windows are UPVC and the sills are wooden and rotten. Approx length of the sills - L:107cm x W:27cm. Possibly need one wooden window frame replaced too. Just sill/frame installation as I am happy to seal and paint them myself. To start ASAP please. Many thanks"
