Leaky Windows? Here are Four Likely Reasons!

06 June 2019

From a beauty standpoint, your house windows offer panoramic views.  From a practical standpoint, they protect your home from nature’s elements.  When air and water infiltrate your windows, their ability, functionality and energy efficient properties are compromised.  Here are four reasons windows can leak air or water.

Inadequate Installation

Sadly, there are a lot of areas where home window replacement can go wrong.  These include caulking, insulation, and flashing.  Windows that are not correctly leveled will compile water and lead to accumulation.  Many of these window installation mistakes are not immediately detectable. However, if botched, window leaking and dry rot can ensue.  That’s why it’s so important to work with a company whose window installers specialize in that area, rather than toggling between specialties.  This allows them to encounter numerous scenarios and understand the correct window installation approach each time.window install

Attic Condensation

Frosty attics due to subpar insulation, ventilation, and air sealing can actually spell trouble for your home windows.  As temperatures warm, the frost melts.  In some instances, this can cause water to drip down the home’s walls and filter in between the window casing and extension jamb.

Window Seal Failure

Double and triple pane windows have glass packs that contain argon gas.  Should the argon gas leak out, the window’s energy efficient properties cease.  Once windows reach the end of their lifespan, window seal failure occurs.  This is why the best replacement windows are not builder grade.  The best replacement windows in Minnesota are built to handle the substantial temperature swings and often are locally manufactured.  It’s a red flag if you notice ice formation in between the window glass panes, as this often signals that window seal failure has occurred.

Poor Home Design

One of the functions of a home’s overhangs is to shelter torrential downpours from penetrating your home’s windows.  If overhangs are missing, lacking in size, or have an improper slope, there’s an opportunity for water to enter your home via the windows even if they are securely closed.
