Like most things on the inside and outside of your home, windows and doors do require maintenance. Most manufacturers provide care and cleaning instructions with their products, which should be followed. Here are a few key maintenance considerations.
Glass, sash and frame surfaces should be kept clean, but petroleum-based cleaners and solvents should not be used. Additional, you should not use a razor blade, putty knife or abrasive pad. Particular care should be given to sills and track areas. Keep free of dirt, dead insects and other debris. Most windows and doors use a water drainage or “weep” system in the frame to drain excess water from heavy rains to the outside. Care should be taken to keep weepholes clean without damaging weephole covers/baffles.
Weather-stripping and hardware should be cleaned and maintained periodically. If weather-stripping is excessively worn, windows and doors cannot seal properly. Hardware components, such as sash locks, operators and patio door rollers, must be operable for security and life safety purposes. If any of these components are no longer functional, they should be replaced.
