‘uPVC’ (unplasticized polyvinyl chloride) windows have become increasingly famous due to their durability, energy efficiency, and low maintenance requirements. However, ‘uPVC’ windows can encounter issues over time like any other type of window. Understanding these common problems and knowing how to fix them can help homeowners ensure their windows remain in top condition for years to come. 

In this article, we will explore some of the most prevalent ‘uPVC’ window problems and provide effective solutions to address them.

  • Difficulty in Opening or Closing the Window

    One of the most common issues with ‘uPVC’ windows is difficulty in opening or closing them smoothly. Several factors, including dirt and debris buildup in the window tracks, misalignment of the window sash, or worn-out hardware, can cause this problem.

    Solution: Contact a reputable window repair company to inspect and address the issue. A professional technician will assess the window tracks, sash alignment, and hardware to identify the root cause of the problem. They will use specialized tools and expertise to realign the sash, replace worn-out hardware, and ensure the smooth operation of the ‘uPVC’ window.

  • Leaky ‘uPVC’ Windows

    Leaky windows can cause drafts, leading to energy loss and reduced indoor comfort. Leaks in ‘uPVC’ windows usually occur due to gaps or cracks in the window frame or seals, which can result from wear and tear over time or poor installation.

    Solution: Inspect the window frame and seals for any visible gaps or cracks. Contact a professional window repair company for larger cracks or gaps to address the issue adequately. Additionally, check the condition of the weather stripping and replace it if necessary.

  • Condensation Buildup

    Condensation forming on the interior surface of ‘uPVC’ windows can be a common problem, particularly during cold weather. It occurs when warm, moist air inside the house comes into contact with the cold surface of the window, leading to water droplet formation.

  • Cracked or Damaged ‘uPVC’ Window Frames

    Having cracked or damaged ‘uPVC’ window frames can be a concerning issue for homeowners. Over time, these frames might develop cracks due to extreme weather or accidental impacts. These cracks can worsen and compromise the window’s overall structural integrity when left unattended. Not only does it affect the window’s appearance, but it also reduces its effectiveness in providing insulation and security.
