We have received lots of calls from customers all with the same problem. Windows are rotten. Yes, English weather is too damp. This ruins everything made from wood. Because of this, we shoulden't forget about window maintenance. Very often, we replace sills, and always try to use sills from hardwood. Before fitting the sill, we prime, undercoat and paint once. After installation we fill all the joints, and then add another final coat of paint. Normally, we recommend our customers to do the maintenance for the windows every 4years. We charge normal sized windows around £300, for Carpentry maintenance and repainting. We thunk this doesnt cost that much to keep your windows in a good condition.
