Proper care for your replacement windows and door glass is important to gain the maximum effectiveness of insulating, Low-E or reflective glass. Any of the “Don’t” actions listed below can damage the glass surface or destroy the insulating glass seal.

  • DON’T: use any petroleum-based cleaners or caustic chemicals on your glass.
  • DON’T: use a razor blade, abrasive pad, or putty knife to clean the glass.
  • DON’T: use a high-pressure spray nozzle when rinsing your glass after washing.
  • DO: clean glass with mild dish soap and water. Rinse thoroughly with clean water and wipe dry with a soft cloth to avoid water spots. Homeowners are also allowed to use commercial glass cleaners as long as they are “Ammonia Free.”
  • Avoid washing glass in direct sunlight for best results.
  • DO: clean screens by first removing, then washing on a clean, flat surface with mild soap and water solution using a soft brush. Rinse, dry, and reinstall.

Water condensation can occur on your window and door interior surfaces if certain conditions exist. Often it’s a warning to you that excessive moisture exists in your home that may facilitate mold growth. Condensation on interior window surfaces results from higher moisture content in the air, contacting lower temperature surfaces on the glass or frames. The higher your home’s internal humidity and the lower the outside air temperature, the more condensation can occur.

  • DO: check all window sashes for smooth and regular operation. Increase interior home ventilation and air exchange devices if needed.
  • DO: use your exhaust fans, especially when showering.
  • DO: consider installing a dehumidifier. Use ceiling fans to improve air circulation.
  • DO: open windows and doors when practical to allow interior moisture to escape.


As with all painted finishes, natural weathering will occur over extended periods. Proper care of your painted surfaces is essential in maintaining the luster and color of the finish. Overextended periods of exposure to the elements, your windows may require professional touch up or re-application of the finish.

  • DO: Use a soft wet brush or absorbent cloth to remove debris stuck to the painted finish carefully.
  • DO: periodically wash the finishes using warm water, and a mild detergent on a soft absorbent cloth.
  • DON’T: use solvents or solvent-based cleaners of any kind on the finishes.
  • DON’T: use a dry cloth or hard bristle brush to clean the finishes.


  • DO: lubricate the moving parts of the window and door hardware if not operating smoothly. Use only a spray silicone product to lubricate moving parts, being careful not to apply excessive amounts. Wipe up any drips or spills. In salt-air environments, monthly cleaning and lubrication may be necessary to preserve function (see the text of warranty on the reverse side for the exclusion of warranty coverage for the functionality of hardware in corrosive environments).
  • DO: inspect weather stripping on operable windows and doors to be sure it seals evenly when closed.
  • DO: make sure that the track area is kept clean. Frequent vacuuming will clear any accumulated dirt and dust.


Windows and doors use a simple drainage system or ‘weep’ holes designed in the frame itself. These water drainage pathways must be kept clean and clear of any obstructions to operate effectively.

It’s normal for water to accumulate in the sill or track area during a period of wind-driven rain. The weep system is designed to allow the water to drain to the outside as water builds up, or outside wind pressure subsides. Clogged weep holes may prevent excess water from draining. Over time standing water can damage your window or door and lead to structural damage from mold, mildew, and wood rot if water enters your wall cavities.

  • DO: keep all sill or track surfaces clean of dirt and debris.
  • DO: make sure that exterior weep holes are clear of any debris, stucco, sand, or other obstructions.
  • DO: use a small, soft brush (such as an old toothbrush) to clear openings.
  • DO: regularly inspect the exterior perimeter of your window and door frames for any cracks or cracks in the adjacent siding material that can cause moisture to penetrate. If a crack appears, seal with a good grade of sealant according to the sealant manufacturer’s instructions.
