Interior window condensation occurs when warm air from inside the house condenses on cold windows. This type of condensation is the most common and causes windows to become hazy. Exterior window condensation usually occurs from outside dew. This is natural and is easy to fix.

Condensation between the window panes can also occur if the window seal is no longer in tact. Another factor can be the “desiccant” is failing. This is the substance used to absorb moisture from the inner air space.

Window condensation can become a serious issue. If left untreated, condensation can cause wood rot, molding, and plaster damage. Luckily, we’re here to provide prevention tips to make window care easier.

How to Prevent Interior Window Condensation

Open Your Windows. Opening your windows may allow some of the trapped warm air out.

Buy Moisture Eliminators. Products, such as DampRid, help reduce damage by collecting moisture from the air.

Use Fans. You can use ceiling fans or powerful desktop fans when cooking or showering. These activities release moisture when done for long periods of time. Ceiling fans also help push air from the top to the bottom of the room.

Turn off or turn down Humidifiers. Humidifiers cause windows in rooms to accumulate moisture from constant use. Using this less can reduce the amount of moisture in the air. You can also buy a dehumidifier.

Apply Weather Stripping. Sealing your windows helps keep warm air from leaving your household. It also prevents cold air from coming inside. If your windows have been recently installed, your window dealer can apply weather stripping, if under warranty.

Move Plants. Moving plants that are near windows might help reduce condensation.

Buy A Window Insulation Kit. You can buy a window insulation kit from a local hardware store. These kits prevent interior condensation when installed on the inside. Additionally, these kits can add energy efficiency savings to your home.

How To Prevent Exterior Window Condensation

Rain X can help to reduce the amount of exterior window condensation by prohibiting water to gather on top of the glass. Additionally, you can wait for the sun to evaporate much of the water on the glass.

Water in Track Area

1. After heavy rain, water may begin to collect on the track. This can be because of weep hole clogging. Check weep holes towards the bottom corners of the window to ensure they are not clogged by debris or dirt.

2. Lock windows to create a tighter seal. This is most helpful during heavy rainfall. Locking windows creates a tighter seal than simply closing the window.

Windows that have proper drainage and locked shut will not experience water issue. If problem still persists, it may be due to leaks coming from the roof or wall.


Frame Cleaning – To clean your frames, vacuum dirt and debris from the track. Mild soap and warm water is best when cleaning window and door frames. Finally, rinse completely with clean water and wipe dry.

Glass Cleaning – Clean window glass with mild soap, warm water, and a soft towel. Specialty glass cleaners, such as Windex, works best. Never clean glass in direct sunlight. Cleaning during hot days may shatter the glass.

Locking Mechanisms – Operate locking mechanisms and make adjustments if loose or unsmooth. Check for any rust or corroded parts and replace if necessary.

Sash and Panel Inspection – This is the operable part of the window. When checking the sash, check the part of the window and frame around the glass. Make sure it still fits snug and does not move. Check for cracks or fogging between the glass panes.

Check Tracks – Use a non-oily lubricant, such as Paraffin Wax, if windows and doors are getting tough to open or close. Wax helps to not collect grime and dust.

Weather Stripping and Sealants – Inspect the seal and caulking around your windows and doors. Look for for any cracks or tears that are visible. Healthy weather-stripping and caulking will protect you from water and air leaks. Reattach any parts that have ripped or torn. Apply more caulking if necessary.

Weep Holes – Weep holes help drain moisture from your windows and patio doors. Check the exterior bottom corners of your windows to ensure holes are clear of dirt and debris.

Screens – You can remove a screen by pulling at an angle or pulling the screen tabs outward. Spray with water and brush with a soft bristle brush.
