Window Care and Maintenance

Taking care of your investment

A little TLC will go a long way in prolonging the life of windows. Modern designs have reduced the requirements for homeowner maintenance, but there are still a few simple tune-ups you should do once or twice a year.

Remember to read your warranty to make sure you're not going to invalidate it by trying to fix a problem yourself. Get in touch with GMP if you have any doubts about maintenance of windows, doors or siding.

Seven steps to trouble-free windows

  • Sweep out and clean the tracks of slider windows.
  • Lubricate the slide tracks on the operators twice a year (after cleaning them, not before), using silicone spray from a home supply store. Do not use oil-based lubricants.
  • If you have wood windows: keep an eye on the paint because if the paint cracks or peels and the water gets in, the wood will start to deteriorate.
  • Interior of wood windows: excessive humidity inside the house can damage the stain or paint finish of a wood window.
  • Any condensation, which can form from time to time, should be wiped dry to remove the moisture from the window.
  • Inspect the caulking every couple years to ensure the seal is still intact.
  • Remove screens every winter to allow for increased airflow to the glass.
