  • What are the most common causes of leaks in window, storefront, or curtain wall systems?

    Leaks can originate from several points within a window or curtain wall assembly. The most common issues we encounter include:

    • Aged or deteriorated joint sealants that have reached the end of their service life
    • Improperly installed glazing gaskets that allow water to bypass the glass-to-frame interface
    • Missing or poorly designed subsill systems that fail to manage water drainage
    • Condensation in older window units manufactured before thermal breaks became standard
    • Improper through-wall flashings above the window—such as at masonry lintels—which can misdirect water into the wall cavity

    At R.E. Kelley, we don’t just repair the window system itself—we also evaluate and address the surrounding structural conditions to ensure a complete and lasting solution to water intrusion.
