When installed correctly, windows are often fixed with a nail flange placed flat against the wall framing. The window would also have a sealant behind it, further fortified with some flashing tape over the top. The window is finally sealed and will only need to be taken down if there's a problem and replacement is required.
There are many reasons leaking occurs - poor installation, wear, and tear, low-quality materials, etc. Here is all you need to know about leaking window features, what causes leaking windows, and how to install a leak-proof window.
Why Do Windows Leak?
Window leaks can be caused by several reasons, from poor window installations to old and worn windows. The basic process behind leaky windows is that the sealing components have broken down, and they can no longer withstand pressure as they should.
Having leaky bow windows can be inconvenient and hazardous. It could cause damage to your home from infiltrating harsh weather elements, mold, and mildew growth. Leaking windows could also lead to wood rot and significant foundation complications and deterioration! Common causes of window leaks include:
- Poor Installation
- Low-Quality Windows
- Poor Glass Seal
- Faulty Caulking - flexible substance used to seal gaps, cracks, and joints
How Can You Find Air Leaks In Your Home Windows?
The last thing you want to do is ignore leaky windows or delay window replacements. So, how can you identify window leaks? Here are some ways to spot leaking windows:
- When it's not raining, water and cloudiness in your glass show that your window has a bad seal and has lost all its insulating gas. This makes it less energy efficient than it might once have been.
- Water on the walls
- Cracks or gaps show that your window sealant has gone bad
- Stained glass and window frames
- Dripping water inside your home when it's raining outside
- Peeling or bubbling paint
- Rotting wood on the exterior and cracking around window sills
- Musty odors on the windows and surrounding walls.
How To Install Leak Proof Windows
The key to having leak-free windows is to have experts from a trusted window installations company like ours do the job. We take additional measures to prevent water intrusion and thoroughly execute all processes. Here are the basic steps to installing a leak-proof window:
- Take out the old window and prep the opening for installation
- Apply flashing tape on the windowsill beneath and vertically from 4 to 6 inches to overlap the horizontal flashing. Wrap the flashing tape around the sheathing prevents water from penetrating the flashings and prevents water from soaking through.
- Apply a large bead of caulk on the upper border of the window opening before flashing.
- Flash the overhead part of the window opening with metal flashing instead of tape where the has been laid; this prevents eventual loosening as water will drip down from above and weaken the adhesive.
- Apply another beat of caulk over the screwed-in metal flashing for extra security.
- Set the window properly and ensure that it's correctly aligned with no gaps
- Use high-quality expansion foam and caulk inside and out to guarantee years of unyielding protection, and just like that, you have your leak-free window installation all done!
