Common UPVC Window Problems and How to Fix Them

UPVC windows have become increasingly popular due to their durability, energy efficiency, and low maintenance requirements. However, like any other type of window, UPVC windows may encounter occasional issues that require attention. In this blog post, we will discuss some common UPVC window problems and provide practical solutions to fix them. By understanding these problems and their remedies, homeowners can ensure their UPVC windows continue to function optimally, prolonging their lifespan and enhancing the overall comfort of their homes.

Sticking Windows 

Sticking windows are a prevalent problem with UPVC windows, often caused by changes in temperature and humidity. To address this issue, start by cleaning the window tracks and frames to remove any dirt or debris that may be hindering smooth operation. Apply a silicone-based lubricant or a specialized UPVC window cleaner to the tracks, ensuring all moving parts are adequately lubricated. If the problem persists, you may need to adjust the hinges or contact a professional to realign the window.

Drafts and Air Leakage 

Drafts and air leakage can compromise the energy efficiency of UPVC windows, leading to discomfort and increased energy bills. Inspect the window seals for any signs of wear or damage. If the seals are deteriorated, consider replacing them with new ones. In some cases, a simple adjustment of the window sash may be sufficient to eliminate drafts. Additionally, using weatherstripping tape around the window frame can provide an extra layer of insulation and prevent air leakage.


Condensation on the inside of UPVC windows is a common issue, especially during colder months. It occurs when warm, moisture-laden air comes into contact with the cooler window surface. To mitigate condensation, ensure proper ventilation in the room by using extractor fans or opening windows regularly. Additionally, using a dehumidifier can help reduce excess moisture in the air. Consider installing trickle vents, which allow controlled airflow and help prevent condensation buildup.

Broken or Faulty Locks 

Faulty locks compromise the security of UPVC windows, making them vulnerable to break-ins. If you encounter a broken or malfunctioning lock, first try cleaning and lubricating it to remove any debris or obstructions. If this doesn’t solve the problem, the lock mechanism may need to be replaced. Contact a professional locksmith or window manufacturer to obtain a suitable replacement lock and ensure it is installed correctly for optimal security.

Damaged or Foggy Double Glazing 

Over time, the double glazing in UPVC windows may develop cracks or become foggy due to moisture penetration. This not only affects the window’s aesthetic appeal but also reduces its insulating properties. In such cases, the entire double glazing unit may need to be replaced. Contact a reputable window specialist who can measure and install a new double glazing unit tailored to your specific window frame.

UPVC windows offer numerous advantages, but like any other component of a home, they can experience issues over time. By addressing common problems promptly and employing the suggested solutions discussed in this blog post, homeowners can maintain the functionality, energy efficiency, and security of their UPVC windows. However, it is essential to remember that some complex issues may require professional assistance. Regular maintenance and care are key to ensuring the longevity and optimal performance of UPVC windows, enhancing the comfort and value of your home for years to come.
