7. Window sealing/windowsill repair

With time, the old window seals crumbled, resulting in water staining the inside of the building. For this job it was necessary to remove the old seals made of improper materials and apply new ones made of proper materials. The whole work was nicely finished without any unevenness. It looks as if nothing was done. ;) On the other window it was necessary to remove residues of damaged windowsill.
