Analyze and fill wooden windows

Damaged old windows can often still be rescued by thorough trowelling. Modern fillers can cover relatively large damages if they are kept by a healthy and stable substance. Anyone who trowels a wooden window will think best of the work of a dentist when filling tooth holes.

Looking for moisture

To make a comprehensive inventory, a dry day with outside temperatures between 15 and 25 degrees Celsius should be chosen. The casements are unhooked and examined separately. The first attention is possibly existing moisture in the window frame.

If there are crumbly and loose wood spots, they should be scratched on the surface in order to look for deeper, hidden moisture. Mold and water marks indicate hidden moisture. If the frame is damaged under window seals, the window seal must be replaced.
