Window Seal Failure: 3 Common Culprits to Blame

You’ll need to deal with seal failure in your windows at some point. And in order to determine the appropriate solution, you’ll need to first understand what’s causing window seal failure in the first place. Renewal by Andersen of Rapid City, a reliable replacement window contractor, shares more of what you need to know. 

Window Seal Failure: 3 Common Culprits to Blame

1. Old Age

Window seal failure is common in older windows, which don’t benefit from the same modern weather protection methods used in windows today. Because of this, older windows are more prone to damage, allowing for holes, cracks, and other openings in the frames, which in turn, compromise their seal. You can replace these windows’ weather stripping to keep them intact, but it may not work in the long term.

2. Inclement Weather

Different weather conditions can damage your windows in different ways. Blistering sunlight, for example, can warp the window frames, especially if they’re made of vinyl. Exposure to wind-driven rain may also cause certain types of seals to lift up and create gaps where air can leak through.

3. Poor Installation

Some contractors take shortcuts in window installation. Perhaps they’ve damaged the window seal during the job. Maybe they haven’t allowed the sealant enough time to set. Whatever it is, it can only lead to one thing – window seal failure.

The Best Solution

Most solutions to window seal failure are temporary at best. To actually deal with this issue and maintain the thermal comfort and energy efficiency of your home, you need to replace your old and failing windows with newer and better ones. As a leading window installation company, Renewal by Andersen of Rapid City can help you with this. With the quality replacement windows we offer, you won’t have to worry as much about seal failure.

Renewal by Andersen® windows uses revolutionary Fibrex® composite for sashes and frames. It combines the strength and insulating value of wood with the low-maintenance performance of vinyl. This allows for windows that are not only impervious to most types of damage but also create a durable and tight seal that prevents air leakage and significant energy loss. What’s more, their double-pane construction, plus the argon gas blend filling the space between the panes, provide an effective thermal barrier. As a result, you get to keep your home’s indoor environment consistent and comfortable, minus the high energy bills.
