There are so many reasons why your Phoenix, AZ windows might leak. The most common problem is faulty installation. But it could also mean the window is worn out or has worn-out parts. If a window is leaking, you need to take it seriously. If not addressed immediately, a small problem could end up damaging the substructures of the home. Here are some common causes of window leaks to help you figure out the problem and get things fixed.

1. Faulty Installation

When getting replacement windows, installation is such an important facet of the process. Window installation takes time, training, and the proper tools to get the job done right. Many homeowners try to DIY the project and in short order, they end up with leaky windows.

2. Windows Not Plumb or Level

Another common cause of leaks is a window that is not plumb or level. Again, this traces back to the installation and making sure measurements are exact. Otherwise, a window that is not properly leveled will begin to collect and accumulate water.

3. Poor Seals on Windows

Expanding foam is one of the most common ways to seal windows. If used correctly, the expanding foam helps avoid leaky windows. But too little foam could leave air channels that open between the window and the wall. These will eventually allow water to come through.

4. Unsecured Caulking

Caulking serves as the initial barrier against leaks. The material needs to be intact. But with time and weather exposure, caulking can wear out and break down. And you might start to notice it peeling away from the windows, leaving them unsecured. If the caulk is damaged, broken, or missing you should try to reseal the area as soon as possible.

5. Neglected Paint Seal

A paint seal is another way to enact an initial barrier against moisture leaks. This means the paint overlaps slightly onto the glass. The continuous membrane will create a seal to stop water penetration and ensure moisture protection. Professional painters know and practice this.

6. Poor Glass Seal

Have you noticed a collection of condensation between the panes of glass on your windows? This means the seals on the insulated glazing units have failed. The inert gas has likely leaked out and these windows are no longer working at peak performance. A bad glass sea is not something you can fix without getting a replacement window.

7. Lack of Proper Overhangs on the House

Home design can also contribute to window leaks. Windows need a proper overhang to protect against water draining off the roof.

8. Problematic Fascia Boards

Fascia boards are another aspect of home design that need to be properly angled to direct water away from the windows. If they are not angled right, this can cause leaks.

9. Defective Products

While less common, defective products can be a cause of window leaks and should not be disregarded. Nothing is more frustrating than getting new windows in place only to discover you already have cracked glass or a leaky frame.

10. Possible Wall Leaks

Have staining around your window? Maybe it isn’t a window leak, but a wall leak. Check the walls before sealing any cracks and gaps.

Do you have leaky Phoenix, AZ windows? This problem won’t solve itself. You need to figure out the cause of the leak and address it as soon as possible if you want to protect your home.
