Is it possible to restore old windows?

Many people own real estate, which has wooden windows.

At one time there was a decline in their popularity, but modern manufacturers have managed to prove that natural wood windows can indeed be of good quality. Practice shows that such windows require periodic maintenance, which significantly extends their operational life. Modern wooden windows from well-known manufacturers really have very good reliability and performance properties, but do not forget to take care of them. Only in this case the service life can reach several decades. Technologies for processing natural materials do not stand still, so windows made of natural wood can actually be useful and durable.
