These metal casement windows were severely corroded with the bottom rails completely dissentegrated. The glass and window furniture was removed so that the steel frames could be cleaned of all active corrosion.
New bottom sections were fabricated and welded into position whilst the handles and latches were cleared of corrosion build up and restored. The frames were then glazed, painted and the brass pivots polished to give a lovely finish. After they were tested and adjusted to open correctly, they were refitted in the stone summer house at the grounds of Penllyn Castle.
