Common Causes of Window Seal Failure

Not to mention, regulating the temperature will be more costly. Obviously, efficiency is one of the top priorities for most homeowners and eventually windows will break down and replacement windows in Portland, OR is inevitable. But knowing the causes of window seal failure can empower homeowners, allowing them to know what to watch for and how to prolong the life of their windows. Here are some of the most common causes of window seal failure:

Deferred Maintenance

Maintenance on windows is key. This doesn’t mean simply washing the glass every couple of months. Proper window maintenance involves cleaning and maintaining the frames, seals, and mechanical systems that keep the windows in peak condition. Unfortunately, very few homeowners get the chance to see the manufacturers’ guides on proper maintenance. And deferred care or improper maintenance can actually make things worse. There is no reason to ever use harsh chemicals, abrasives, or power washers on your windows. In fact, these will most certainly result in premature seal failure.

Natural Elements

Windows are meant to defend the interior of the home. This means they suffer the bulk of the natural elements like endless rain, hail, snow, and ice. And windows are meant to withstand even the toughest conditions, they are not invincible. The window seal material has its limits and prolonged exposure to the elements will predictably cause corrosion.

Moisture Damage and Mold Growth

The problem with window leaks is that what often starts as a small issue can quickly progress into a more serious one. This is the case with water damage. A small leak may not seem like much to worry about. And in fact, spotting a leak early can be almost impossible. But before long the leak will get worse and continue to cause issues with peeling paint, sagging drywall, and rot. Moisture damage can also lead to mold growth, which is dangerous for both the structure of the home as well as the health of the occupants.

Temperature Extremes

The building materials used to manufacture windows are rigid—not flexible. And these materials do not all have the same rate of thermal expansion and contraction. That means the materials shrink and expand differently due to temperature changes. Now ideally, the window seal is meant to take the brunt of the work. It will stretch and compress to keep the gaps between the materials airtight. But the pressure from prolonged exposure to extreme temperature changes will cause the material to wear out faster, disintegrate, and separate from the frame.

Faulty Installation

Window installation is not something you want to leave to a novice. The work is meticulous and one mistake could result in seal failure, or even worse, failure of the entire unit. If you want your windows installed right the first time, you need to leave to job to the professionals who get training directly from the manufacturers.

These are just five things that can cause window seal failure. But there are so many factors that could be causing a leaky window. If you have a leaky window and are ready for replacement windows in Portland, OR do not hesitate to call our professionals for an in-home consultation.
