What Are the Common Causes of Window Seal Failure?

Energy-efficient windows help reduce your heating and cooling costs. With these windows, your HVAC system doesn’t need to work as hard to keep your home comfortable. On the other hand, units with broken seals can allow drafts into your home.

Learn the common causes of window seal failure from a leading replacement window contractor.

Age

Older windows are more likely to experience seal failure. This is because outdated weather protection methods are more prone to damage.

Harsh Elements

While window seals are made to resist different elements, there’s only so much they can take. For instance, certain kinds of seals can allow water to seep behind it when constantly exposed to heavy rains. Rust can occur when water comes in contact with the metal components of certain types of weatherstripping.

Improper Installation

Even the best units can experience issues early when not installed properly, so make sure to hire a reputable contractor for residential window services. The window seal will not work properly when it has not been fitted correctly. It’s the same for weatherstripping. Your contractor should use the right tools and fasteners for fitting weatherstripping.

Temperature Changes

The location of window seals makes them more exposed to extreme temperatures. Constant exposure to sudden temperature changes can cause the seal to sag, shrink, or sag, making its weather protection less efficient.

Poor Maintenance

Weatherstripping usually comes with instructions that state what you should do to maintain it and keep it efficient. Manufacturers may mention products that can and can’t be used for cleaning the weatherstripping. Make sure to follow the manufacturer’s recommendations for maintenance to prevent damage and a voided warranty.
