Had new vinyl replacement windows installed in our house about 6 years ago. Low E, double pane and the type that tilts for easy cleaning. Well every window in our house leaks at the point where the insulation or seal is between the stationary part of the window and the part that tilts. It is ironic that all of the windows leak at those points. My question is if I can put a thicker seal or insulation between the two points or just install window kits? Is this normal for tilt windows to leak over a period of time. Very curious now. Thank you for any advice...Ray
They should not do that. Most windows have a 10 yr warranty for mechanical components, contact the manufacturer and the installer/seller. If a manufacturing defect they will fix it. If an installation defect, that is up to the installer, but the manufacturer can advise or help.
