How To Maintain Your Replacement Windows

Vinyl replacement windows and patio doors are known for being low maintenance, but they will need occasional cleaning to keep them in the best shape possible.  Proper replacement window maintenance will ensure your home windows and patio doors will look great, retain value, and reduce energy costs for years to come.

Frame Cleaning

  • Vacuum dirt from window sill and track areas before washing.
  • Clean window and door frames with a mixture of mild dish soap and water.
  • Abrasive or caustic cleaners or solvents are NEVER recommended.
  • Always rinse completely with clean water and wipe dry.

Drainage Systems

  • Check to make certain the drainage or “weep holes” are always clear of dirt, stucco, sand or building materials, both inside and outside the window or door in the bottom of the frame.
  • It’s normal for water to accumulate in the sill or track area with wind driven rain.  The water is intended to drain to the outside as water builds up or outside pressure subsides.
  • Keep sill or track areas clean of dirt or debris.
  • Use a small, soft bottle brush to clear openings.

Glass Care

  • Clean glass with mild dish soap and clean water.
  • Avoid washing glass in direct sunlight.
  • Never use any petroleum-based cleaners or caustic chemicals on your glass.
  • Never us a razor blade, putty knife, or abrasive pad to clean the glass.
  • Never us a high pressure spray nozzle when rinsing your windows and doors after washing.
  • Abrasive or caustic cleaners are NEVER recommended because they might cause permanent damage to the finish/coating or the glass.

Condensation & Mold

  • Condensation can be a natural occurrence in the home.
  • Check all windows and doors for airtight seals.
  • Open windows and doors whenever practical to allow interior moisture to escape.
  • Regularly use ceiling fans to circulate the air.
  • Use exhaust fans in rooms with high humidity (bathrooms/kitchen).
  • Use dehumidifiers to reduce the amount of moisture inside homes with high humidity.


Clean screens by first removing the screens, then washing on a flat, clean surface with mild dish soap and water and a very soft brush. Rinse, wipe dry and reinstall.


Maintaining your window caulking is the number one tip we can give replacement window customers.  Caulking may be necessary to seal the window frame or trim package against water and/or air filtration.  Many issues encountered by our customers can be prevented by proper caulking maintenance.
