How can I get rid of the condensation that forms on my window/patio door glass panes?

The answer varies, depending upon whether the condensation is on the Exterior Pane, the Interior Pane or Between the Panes.

Exterior Pane

Condensation on the outside of your windows or patio doors may occur during spring and in the fall, usually when cool nights follow a warm day. It is a result of moisture in the air exceeding certain limits and the temperature of the glass falling below the dew point in the air. Condensation on the exterior glass panes is a natural phenomenon, especially for energy-efficient insulating which restricts the airflow between the panes of glass. This condensation will evaporate once the day warms.

Interior Pane

Condensation on the inside of a window indicates the humidity levels inside the room are higher inside than outside. Excess moisture on the inside of a window is unsightly and obstructs your view. Follow these easy steps to reduce the risk of excessive condensation.

  1. Check all windows and patio doors for smooth operation and airtight seals.
  2. Use exhaust fans regularly in rooms with high humidity (bathrooms, pool rooms, kitchens, etc.)
  3. Use a ceiling fan to continuously circulate air.
  4. Use dehumidifiers to reduce the amount of moisture inside homes with humidity problems.
  5. Open windows and doors when practical to reduce excessive moisture inside a home.

Between the Panes

When the seals along the outer perimeter of glass fail and allow moisture to penetrate the space between panes of insulated glass, your window or door will appear cloudy or fogged. Please check and make sure the glass does not have chemicals or pollutants on the outside surface. Once you confirm that the condensation is between the panes, the insulated glass unit will need to be replaced.

Can I paint my vinyl windows?

Painting your vinyl windows is considered an alteration to the vinyl finish and will result in the warranty being voided. Additionally, some paints, particularly dark colors, can cause heat buildup within leading to premature failure of the vinyl and possibly the insulated glass unit.

Can I apply a window tint to my products?

We do not suggest adding a tint to your window glass as this will void your warranty on the insulated glass unit. Applying tint can cause excessive heat to the insulated glass causing the unit to prematurely fail.

Can scratched glass be repaired?

Typically, scratches in glass are the result of debris during construction or dirt on the glass. If care is not taken to lightly flush and remove the debris it could etch the glass surface resulting in a scratch. Milgard does not manufacture a product to remove glass scratches but there are companies that manufacture polishing compounds that remove scuffs, light scratches and deposits on glass that can't be cleaned with regular washing. As a guideline, if the scratch is deep enough to catch the edge of a fingernail, it's too deep to remove.

The top sash of my double-hung window won't stay up. I put it up and then it slowly slides down. How can I keep the top sash in place?

Often times the top sash is not pushed completely in place to allow the retaining lip to engage the weather-stripping and hold it in place. Make sure the sash is completely raised to eliminate potential drifting.

Why aren't window screens part of the lifetime warranty?

Due to the fragile nature of window screens, a lifetime warranty is not provided. Milgard will replace any window or door screen frame and mesh that are defective in materials or workmanship at no charge to the Original Purchaser (including parts and labor) for the period of one (1) year after the date of purchase of the home for new construction or in other cases one (1) year from the installation of Milgard windows.

There was water on the inside of my window during a recent storm. Is this normal? How can I fix it?

Though this may be alarming at first, water on the inside of you window may be present during rain storms. Our windows and patio doors have a specially designed "weep" drainage system with vented slots on the exterior bottom of our frames to protect the inside of your home. Proper maintenance of your weep system is required to assure proper drainage.

  1. The weep system allows water to drain to the outside as it builds up. It's normal for water to build up on the sill or the outside track, which is why it's important to keep the sill or track clean of any dirt or debris.
  2. Periodically inspect the weep holes on the exterior bottom rails to make certain they are clear of any dirt or debris. Use a soft bottlebrush to clear openings, if necessary.
  3. A good time to inspect and clean weep holes is when excessive rain is anticipated. We recommend inspecting your weep system annually.
