Problems with Window Seals

It’s nice to enjoy high-quality windows, which don’t require any attention besides regular window cleaning. However, not all windows are created equal. Old and improperly installed windows often suffer from seal failure.

Each homeowner should know what window seal failure is and how to deal with it. Otherwise, it could lead to costly window replacement.

What are Window Seals?

The key purpose of your windows is to maintain a comfortable environment in your home while allowing sunlight to enter the rooms. Window manufacturers are constantly looking for new ways to improve the energy efficiency of windows to protect the environment.

These days, homeowners have a choice of double or even triple-pane windows that feature a seal around the perimeter for a tighter fit. Such windows usually have argon gas in between the panes to create better insulation. Seals keep the gas in and create a special barrier to prevent cool or hot air from entering your house.

Why do Seals Fail?

Different reasons for seal failure exist. If you know them all, you can prevent the problem from happening or turning into something serious.

If window seals fail when windows are new (less than five years old), it’s probably the manufacturer’s fault. A mistake could have been made during manufacturing or installation. Either the installation company or the shipper may have punctured the seal due to careless actions or an honest mishap.

Another reason for seal failure is the wrong choice of window frame materials. Depending on the climate you live in, you should choose appropriate frame materials. For example, wooden frames aren’t suitable for hot and humid environments.

Sometimes seals fail if you don’t take care of the condensation on the windows. Condensation could occur due to poor installation. As moisture settles on the windows, it causes mold and mildew formation. Eventually, it leads to seal failure.

How Can You Identify Seal Failure?

Even if nothing seems to be wrong with your windows, you should inspect them regularly to spot seal damage.

When the window seal starts failing, you may not notice the problem immediately. However, as the weather starts changing during the mid-season, seal failures will become worse due to the expansion and contraction of the materials.

Moisture will start appearing between the panes, and you won’t be able to get it out. The condensation will keep coming and going depending on the weather.

The more moisture appears between the panes, dirt and mineral deposits start settling inside and covering the glass. Eventually, you would have to replace the windows.
